Full Text Available This work examines the teaching approach for chemistry laboratory practicals for first year undergraduate students to determine if the underpinning pedagogical strategy meets the requirements for these students for the remainder of their undergraduate programme. This is based on the knowledge, skills, content and learning outcomes for undergraduate chemistry courses. This work aims to enhance the first year experience of chemistry education by facilitating greater student engagement and “deeper” learning of relevant content during practical laboratory experiences by focusing on the learners’ needs. During this research, a survey of undergraduate science students from 2nd, 3rd and 4th years was carried out to determine if first year chemistry practicals facilitated the development of skills needed in further science education. It concluded that overall there was a positive response to first year laboratory practicals, that students engaged with them and felt they assisted with skills required for subsequent years of undergraduate study. Participants were most satisfied with the organic chemistry experiments while, for the physical/analytical chemistry experiments, the results obtained reiterated difficulties with mathematical calculations that are accepted as an issue in other aspects of third level STEM (Science, Technology, Engineering and Mathematics subjects. As a result of these findings, modifications that were made to the laboratory practical element included a pre-populated workbook supplied to the students and the introduction of pre-laboratory questions to be completed by each student before each session to reduce cognitive load and improve the students’ knowledge and understanding of 2 the purpose and potential outcomes of each laboratory practical. Also, the total first year chemistry syllabus was re-organised, as was the scheduling of the experiments to synchronise the theory lectures with the experiments as far as was

Humans have a flexible motor ability to adapt their movements to changes in the internal/external environment. For example, using arm-reaching tasks, a number of studies experimentally showed that participants adapt to a novel visuomotor environment. These results helped develop computational models of motor learning implemented in the central nervous system. Despite the importance of such experimental paradigms for exploring the mechanisms of motor learning, because of the cost and preparation time, most students are unable to participate in such experiments. Therefore, in the current study, to help students better understand motor learning theories, we developed a simple finger-reaching experimental system using commonly used laptop PC components with an open-source programming language (Processing Motor Learning Toolkit: PMLT). We found that compared to a commercially available robotic arm-reaching device, our PMLT accomplished similar learning goals (difference in the error reduction between the devices, P = 0.10). In addition, consistent with previous reports from visuomotor learning studies, the participants showed after-effects indicating an adaptation of the motor learning system. The results suggest that PMLT can serve as a new experimental system for an undergraduate laboratory exercise of motor learning theories with minimal time and cost for instructors.

PIRATE is a 0.43m semi-autonomous research and teaching observatory owned by The Open University, UK. Since 2010, it has been reserved for several months of each year for teaching astronomy in the OU's undergraduate programme. As students in these courses operate PIRATE remotely rather than travelling to the observatory itself, we chose to investigate whether effective learning was adversely affected by the absence of a more traditional `hands on' experience. We discuss student perspectives on the technologies employed (i.e., remote and virtual investigations), the impact these had on perceived course outcomes, and consider implications for future teaching and outreach.

Surface science has developed into a multidisciplinary field of research with applications ranging from heterogeneous catalysis to semiconductor etching (1). Aspects of surface chemistry are now included in physical chemistry textbooks (2) and undergraduate curricula (3), but the perceived cost and complexity of equipment has deterred the introduction of surface science methods in undergraduate laboratories (4). Efforts to expose chemistry undergraduates to state-of-the-art surface instrumentation have just begun (5). To provide our undergraduates with hands-on experience in using standard techniques for characterizing surface morphology, adsorbates, kinetics, and reaction mechanisms, we have developed a set of surface science experiments for our physical chemistry laboratory sequence. The centerpiece of the laboratory is an ultrahigh vacuum (UHV) chamber for studies of single crystal surfaces. This instrument, shown in the figure, has surface analysis capabilities including low energy electron diffraction (LEED), Auger spectroscopy, and temperature-programmed desorption (TPD). The laboratory exercises involve experiments on the well-studied Pt(111) surface. Students prepare a previously mounted single crystal sample by sputtering it with an argon ion gun and heating it under O2. Electron diffraction patterns from the cleaned surface are then obtained with a reverse view LEED apparatus (Princeton Instruments). Images are captured by a charge-coupled device (CCD) camera interfaced to a personal computer for easy downloading and subsequent analysis. Although the LEED images from a Pt(111) surface can be readily interpreted using simple diffraction arguments, this lab provides an excellent context for introducing Miller indices and reciprocal lattices (6). The surface chemical composition can be investigated by Auger spectroscopy, using the LEED apparatus as a simple energy analyzer. The temperature programmed desorption experiment, which is nearly complete, will be
Luckenbaugh, Raymond W.
Each organic chemistry student should become familiar with the educational and governmental laboratory safety requirements. One method for teaching laboratory safety is to assign each student to locate safety resources for a specific class laboratory experiment. The student should obtain toxicity and hazardous information for all chemicals used or produced during the assigned experiment. For example, what is the LD50 or LC50 for each chemical? Are there any specific hazards for these chemicals, carcinogen, mutagen, teratogen, neurotixin, chronic toxin, corrosive, flammable, or explosive agent? The school's "Chemical Hygiene Plan", "Prudent Practices for Handling Hazardous Chemicals in the Laboratory" (National Academy Press), and "Laboratory Standards, Part 1910 - Occupational Safety and Health Standards" (Fed. Register 1/31/90, 55, 3227-3335) should be reviewed for laboratory safety requirements for the assigned experiment. For example, what are the procedures for safe handling of vacuum systems, if a vacuum distillation is used in the assigned experiment? The literature survey must be submitted to the laboratory instructor one week prior to the laboratory session for review and approval. The student should then give a short presentation to the class on the chemicals' toxicity and hazards and describe the safety precautions that must be followed. This procedure gives the student first-hand knowledge on how to find and evaluate information to meet laboartory safety requirements.

To address the need for reform in undergraduate science education a new instructional model called Argument-Driven Inquiry (ADI) was developed and then implemented in a undergraduate chemistry course at a community college in the southeastern United States (Sampson, Walker, & Grooms, 2009; Walker, Sampson, & Zimmerman, in press). The ADI instructional model is designed to give a more central place to argumentation and the role of argument in the social construction of scientific knowledge. This research investigated the growth in the quality of the student generated arguments and the scientific argumentation that took place over the course of a semester. Students enrolled in two sections of General Chemistry I laboratory at the community college participated in this study. The students worked in collaborative groups of three or four. The students were given a variation of the same performance task three times during the semester in order to measure individual ability to use evidence and justify their choice of evidence with appropriate rationale. Five ADI investigations took place during the semester and the laboratory reports for each were collected from each student and the argument section of each report was scored. All the student groups were video recorded five times during the semester as they generated and evaluated arguments and the quality of the group argumentation was assessed using an instrument called the Assessment of Scientific Argumentation in the Classroom (ASAC) observation protocol. As time was the independent variable in this study a repeated measure ANOVA was used to evaluate the significance of student improvement in each area (argumentation, written argument and performance task) over the course of the semester (Trochim, 1999). In addition, a multiple regression analysis was conducted to evaluate how well the ASAC scores predicted individual scores on both the performance task and the written arguments (Green & Salkind, 2005).

Clinical preparation for practice is a vital part of undergraduate education in nursing. This study explored contemporary constructions of clinical skills laboratories in two nursing undergraduate programs in Norway using qualitative collective case study methods. Data were gathered using individual and group interviews and observation during site visits. The data revealed slightly different ways of organizing teaching and experimenting with use of pedagogical methods to facilitate learning of technical skills as well as encouraging students to activate relevant theoretical knowledge. While there was a lively and striking enthusiasm among staff about the way learning was managed within the laboratories, the pedagogical underpinnings for their particular approaches were less certain amongst participants. The paper concludes with the necessity to provide evidence for the outcome of laboratories learning and investigate suitable pedagogical methods for effective teaching and learning of practice skills. Hence, a need for research on transfer of knowledge and skills between the different sites (academy, clinical settings, and laboratories) is identified.

At the Institute of Optics, University of Rochester (UR), we have adapted to the main challenge (the lack of space in the curriculum) by developing a series of modular 3-hour experiments and 20-min-demonstrations based on technical elective, 4-credit-hour laboratory course "Quantum Optics and Nano-Optics Laboratory" (OPT 253/OPT453/PHY434), that were incorporated into a number of required courses ranging from freshman to senior level. Rochester Monroe Community College (MCC) students also benefited from this facility that was supported by four NSF grants. MCC students carried out two 3-hour labs on photon quantum mechanics at the UR. Since 2006, total 566 students passed through the labs with lab reports submission (including 144 MCC students) and more than 250 students through lab demonstrations. In basic class OPT 253, four teaching labs were prepared on generation and characterization of entangled and single (antibunched) photons demonstrating the laws of quantum mechanics: (1) entanglement and Bell's inequalities, (2) single-photon interference (Young's double slit experiment and Mach-Zehnder interferometer), (3) confocal microscope imaging of single-emitter (colloidal nanocrystal quantum dots and NV-center nanodiamonds) fluorescence within photonic (liquid crystal photonic bandgap microcavities) or plasmonic (gold bowtie nanoantennas) nanostructures, (4) Hanbury Brown and Twiss setup. Fluorescence antibunching from nanoemitters. Students also carried out measurements of nanodiamond topography using atomic force microscopy and prepared photonic bandgap materials from cholesteric liquid crystals.

The undergraduate chemistry laboratory has been an essential component in chemistry education for over a century. The literature includes reports on investigations of singular aspects laboratory learning and attempts to measure the efficacy of reformed laboratory curriculum as well as faculty goals for laboratory learning which found common goals among instructors for students to learn laboratory skills, techniques, experimental design, and to develop critical thinking skills. These findings are important for improving teaching and learning in the undergraduate chemistry laboratory, but research is needed to connect the faculty goals to student perceptions. This study was designed to explore students' ideas about learning in the undergraduate chemistry laboratory. Novak's Theory of Meaningful Learning was used as a guide for the data collection and analysis choices for this research. Novak's theory states that in order for meaningful learning to occur the cognitive, affective, and psychomotor domains must be integrated. The psychomotor domain is inherent in the chemistry laboratory, but the extent to which the cognitive and affective domains are integrated is unknown. For meaningful learning to occur in the laboratory, students must actively integrate both the cognitive domain and the affective domains into the "doing" of their laboratory work. The Meaningful Learning in the Laboratory Instrument (MLLI) was designed to measure students' cognitive and affective expectations and experiences within the context of conducting experiments in the undergraduate chemistry laboratory. Evidence for the validity and reliability of the data generated by the MLLI were collected from multiple quantitative studies: a one semester study at one university, a one semester study at 15 colleges and universities across the United States, and a longitudinal study where the MLLI was administered 6 times during two years of general and organic chemistry laboratory courses.

Full Text Available The goal of an undergraduate laboratory course should be not only to introduce the students to biology methodologies and techniques, but also to teach them independent analytical thinking skills and proper experiment design. This is especially true for advanced biology laboratory courses that undergraduate students typically take as a junior or senior in college. Many courses achieve the goal of teaching techniques, but fail to approach the larger goal of teaching critical thinking, experimental design, and student independence. Here we describe a study examining the application of the scaffolding instructional philosophy in which students are taught molecular techniques with decreasing guidance to force the development of analytical thinking skills and prepare undergraduate students for independent laboratory research. This method was applied to our advanced molecular biology laboratory class and resulted in an increase of confidence among the undergraduate students in their abilities to perform independent research.
A large fraction of the potential graduate students in chemistry come from undergraduate colleges. The exposure of these students to the field of nuclear and radiochemistry is limited by the fact that few professionals actively involved in the field teach at these schools. There is also increasing competition for the limited number of chemistry students by other chemical specializations. Innovative approaches such as a short course to introduce students to nuclear and radiochemistry and some of the needs for undergraduate teaching are discussed. (author) 6 refs.; 2 figs

Chemistry laboratory coursework has the potential to offer many benefits to students, yet few of these learning goals are realized in practice. Therefore, this study seeks to characterize undergraduate students' learning goals for their chemistry laboratory coursework. Data were collected by recording video of students completing laboratory experiments and conducting interviews with the students about their experiences that were analyzed utilizing the frameworks of Human Constructivism and Self-Regulated Learning. A cross-sectional sampling of students allowed comparisons to be made among students with varying levels of chemistry experience and interest in chemistry. The student goals identified by this study were compared to previously described laboratory learning goals of the faculty who instruct these courses in an effort to identify potential avenues to improve laboratory learning.

While there are a variety of undergraduate laboratory experiments in the literature, they tend to focus on specific positron experiments and use specialized equipment that limit their flexibility. Here we present a positron spectroscopy experimental apparatus designed for the undergraduate lab. Rather than specialized pulse processing the apparatus utilizes a PC oscilloscope as its primary data acquisition utility with pulse processing happening in software instead of hardware. This allows the apparatus to explore a variety of physical phenomena with the positron annihilation including material science, 2 and 3 gamma annihilation properties, polarimetry via Compton scattering, QED tests, and local hidden variable theories. The supporting software is flexible and allows students to pursue these experiments through exploration rather than simply supporting data acquisition. St. Olaf College.

An experiment studying the physical principles of electrophoresis in liquids was developed for an undergraduate laboratory. We have improved upon the standard agarose gel electrophoresis experimental regime with a straightforward and cost-effective procedure, in which drops of widely available black food coloring were separated by electric field into their dye components on strips of chromatography paper soaked in a baking soda/water solution. Terminal velocities of seven student-safe dyes were measured as a function of the electric potential applied along the strips. The molecular mobility was introduced and calculated by analyzing data for a single dye. Sources of systematic and random errors were investigated.

Biomechanics education is a vital component of kinesiology, sports medicine, and physical education, as well as for many biomedical engineering and bioengineering undergraduate programmes. Little research exists regarding effective teaching strategies for biomechanics. However, prior work suggests that student learning in undergraduate physics courses has been aided by using the Just-in-Time Teaching (JiTT). As physics understanding plays a role in biomechanics understanding, the purpose of study was to evaluate the use of a JiTT framework in an undergraduate biomechanics course. This two-year action-based research study evaluated three JiTT frameworks: (1) no JiTT; (2) mathematics-based JiTT; and (3) concept-based JiTT. A pre- and post-course assessment of student learning used the biomechanics concept inventory and a biomechanics concept map. A general linear model assessed differences between the course assessments by JiTT framework in order to evaluate learning and teaching effectiveness. The results indicated significantly higher learning gains and better conceptual understanding in a concept-based JiTT course, relative to a mathematics-based JiTT or no JiTT course structure. These results suggest that a course structure involving concept-based questions using a JiTT strategy may be an effective method for engaging undergraduate students and promoting learning in biomechanics courses.
that new experiments which illustrate both fundamental physics and modern technology can be realized even with a small budget. Traditional labwork courses often provide a catalogue of well known experiments. The students must first learn the theoretical background. They then assemble the setup from specified equipment, collect the data and perform the default data processing. However, there is no way to learn to swim without water. In order to achieve a constructivist access to learning, 'project labs' are needed. In a project labwork course a small group of students works as a team on a mini research project. The students have to specify the question of research, develop a suitable experimental setup, conduct the experiment and find a suitable way to evaluate the data. Finally they must present their results e.g. in the framework of a public poster session. Three contributions refer to this approach, however they focus on different aspects: 'Project laboratory for first-year students' by Gorazd Planinšič, 'RealTime Physics: active learning laboratories' by David Sokoloff et al and 'Labs outside labs: miniprojects at a spring camp for future physics teachers' by Leos Dvorák. Is it possible to prepare the students specifically for project labwork? This question is answered by the contribution 'A new labwork course for physics students: devices, methods and research projects' by Knut Neumann and Manuela Welzel. The two main parts of the labwork course cover first experimental devices (e.g. multimeters, oscilloscopes, different sensors, operational amplifiers, step motors, AD/DA-converters). Then subjects such as data processing, consideration of measurement uncertainties, keeping records or using tools like LABVIEW etc are focused on. Another concrete proposal for a new curriculum is provided by James Sharp et al, in 'Computer based learning in an undergraduate physics laboratory: interfacing and instrument control using MATLAB'. One can well imagine that project labs

Scientists at universities across Iraq are actively working to report actual incidents and accidents occurring in their laboratories, as well as structural improvements made to improve safety and security, to raise awareness and encourage openness, leading to widespread adoption of robust Chemical Safety and Security (CSS) practices. The improvement of students’ understanding of concepts in science and its applications, practical scientific skills and understanding of how science and scientists work in laboratory experiences have been considered key aspects of education in science for over 100 years. Facility requirements for the necessary level of safety and security combined with specific requirements relevant to the course to be conducted dictate the structural design of a particular laboratory, and the design process must address both. This manuscript is the second in a series of five case studies describing laboratory incidents, accidents, and laboratory improvements. We summarize the process used to guide a major renovation of the chemistry instructional laboratory facilities at Al-Nahrain University and discuss lessons learned from the project.

Pharmacists in the UK are able to report spontaneous adverse drug reactions (ADRs) to the Medicines and Healthcare Products Regulatory Authority. The level of reporting by UK pharmacists remains low. This could be explained by poor knowledge of ADR reporting. The primary objective of this study was to investigate the level of pharmacovigilance education provided to pharmacy students on undergraduate pharmacy programmes in the UK. A cross-sectional survey was used to obtain data relating to the teaching of pharmacovigilance within schools of pharmacy. The survey was designed to reveal whether core elements pertinent to pharmacovigilance and specifically to spontaneous reporting were taught and to what extent. All of the respondents taught pharmacovigilance within an assessed compulsory module. A small number (23%) did not include pharmacovigilance law within their syllabus. In 54%, the amount of time devoted to teaching pharmacy students about their role in pharmacovigilance was less than 4 h in the 4-year course; only one respondent spent approximately 20 h, the remaining respondents (38%) spent between 4 and 8 h. The amount of time dedicated to the teaching of pharmacovigilance on pharmacy undergraduate degree programmes is low. Considering the importance of spontaneous reporting in drug safety and the shift in the role of the pharmacists, more time may need to be devoted to pharmacovigilance on pharmacy undergraduate courses. By doing so, new pharmacists would be more informed of the important role they play in drug safety and thereby potentially help enhance the level of ADR reporting.

Full Text Available Atomic force microscopy (AFM has been used extensively in nanoscience research since its invention. Recently, many teaching laboratories in colleges, undergraduate institutions, and even high schools incorporate AFM as an effective teaching tool for nanoscience education. This paper presents an optical beam deflection (OBD based atomic force microscope, designed specifically for the undergraduate engineering laboratory as a teaching instrument. An electronic module for signal conditioning was built with components that are commonly available in an undergraduate electronic laboratory. In addition to off-the-shelf mechanical parts and optics, the design of custom-built mechanical parts waskept as simple as possible. Hence, the overall cost for the setup is greatly reduced. The AFM controller was developed using National Instruments Educational Laboratory Virtual Instrumentation Suite (NI ELVIS, an integrated hardware and software platform which can be programmed in LabVIEW. A simple yet effective control algorithm for scanning and feedback control was developed. Despite the use of an educational platform and low-cost components from the undergraduate laboratory, the developed AFM is capable of performing imaging in constant-force mode with submicron resolution and at reasonable scanning speed (approximately 18 min per image. Therefore, the AFM is suitable to be used as an educational tool for nanoscience. Moreover, the construction of the system can be a valuable educational experience for electronic and mechanical engineering students.

A laboratory activity focusing on the topic of natural radioactivity is designed to develop the knowledge and understanding of undergraduate university students on the topic of radioactivity, to appreciate the importance of environmental radioactivity and familiarize them with the basic technology used in radioactivity measurements. The laboratory activity is divided into three parts: (i) measurements of the count rate with a Geiger-Muller counter of some granite samples and the ambient background radiation rate, (ii) measurement of one of the samples using gamma ray spectrometry with a NaI detector and identification of the radioactive elements of the sample, (iii) using already recorded 24 h gamma ray spectra of the samples from the first part (from the Granite Gamma-Ray Spectrum Library (GGRSL) of our laboratory) and analyzing selected peaks in the spectrum, students estimate the contribution of each radioactive element to the total specific activity of each sample. A brief description of the activity as well as some results and their interpretation are presented.
Kinetics is an important part of undergraduate environmental chemistry curricula and relevant laboratory exercises are helpful in assisting students to grasp concepts. Such exercises are also useful in general chemistry courses because students can see relevance to real-world issues. The laboratory exercise described here involves determination of…

Junior medical staff provides a large proportion of undergraduate student education. However, despite increasing numbers of resident-as-teacher training programs, junior doctors may still not be sufficiently prepared to teach medical students. Hence, medical schools should consider implementing formal teaching skills training into undergraduate curricula.

Approximately three years ago, Auburn University replaced its aging Dynamitron accelerator with a new 2MV tandem machine (Pelletron) manufactured by the National Electrostatics Corporation (NEC). This new machine is maintained and operated for the University by Physics Department personnel, and the accelerator supports a wide variety of materials modification/analysis studies. Computer software is available that allows the NEC Pelletron to be operated from a remote location, and an Internet link has been established between the Accelerator Laboratory and the Upper-Level Undergraduate Teaching Laboratory in the Physics Department. Additional software supplied by Canberra Industries has also been used to create a second Internet link that allows live-time data acquisition in the Teaching Laboratory. Our senior-level undergraduates and first-year graduate students perform a number of experiments related to radiation detection and measurement as well as several standard accelerator-based experiments that have been added recently. These laboratory exercises will be described, and the procedures used to establish the Internet links between our Teaching Laboratory and the Accelerator Laboratory will be discussed.

Full Text Available This study emanated from the Integrated Strategic Planning Framework for Teacher Education and Development in South Africa. This Framework proposes that teaching schools should be established in the country to improve the teaching practicum component of pre-service teacher education. A generic qualitative study was undertaken to explore the affordances of a teaching school to enable student teacher learning for the teaching profession. The overarching finding of the study is that a teaching school holds numerous affordances for enabling meaningful student teacher learning for the teaching profession. However, the full affordances of a teaching school will not be realised if a teaching school is viewed merely as a practicum site. Foregrounding a laboratory view of practice work in a teaching school could enable true research-oriented teacher education. A teaching school as a teacher education laboratory would imply a deliberate inclusion of cognitive apprenticeship and an inquiry orientation to learning in the schoo

"Visualization" of chemical phenomena often has been limited in the teaching laboratories to the sense of sight. We have developed chemistry experiments that rely on senses other than eyesight to investigate chemical concepts, make quantitative determinations, and familiarize students with chemical techniques traditionally designed using only eyesight. Multi-sensory learning can benefit all students by actively engaging them in learning through stimulation or an alternative way of experiencing a concept or ideas. Perception of events or concepts usually depends on the information from the different sensory systems combined. The use of multi-sensory learning can take advantage of all the senses to reinforce learning as each sense builds toward a more complete experience of scientific data. Research has shown that multi-sensory representations of scientific phenomena is a valuable tool for enhancing understanding of chemistry as well as displacing misconceptions through experience. Multi-sensory experiences have also been shown to enrich memory performance. There are few experiments published which utilize multiple senses in the teaching laboratory. The sensorial experiments chosen were conceptually similar to experiments currently performed in undergraduate laboratories; however students collect different types of data using multi-sensory observations. The experiments themselves were developed by using chemicals that would provide different sensory changes or capitalizing on sensory observations that were typically overlooked or ignored and obtain similar and precise results as in traditional experiments. Minimizing hazards and using safe practices are especially essential in these experiments as students utilize senses traditionally not allowed to be used in the laboratories. These sensorial experiments utilize typical equipment found in the teaching laboratories as well as inexpensive chemicals in order to aid implementation. All experiments are rigorously tested

Learning in general practice is an essential component of undergraduate medical education; currently, on average, 13% of clinical placements in the UK are in general practice. However, whether general practice can sustainably deliver more undergraduate placements is uncertain. To identify the geographical distribution of undergraduate teaching practices and their distance from the host medical school. National survey of all medical schools in the UK. All 33 UK medical schools were invited to provide the postcodes of their undergraduate teaching practices. These were collated, de-duplicated, and mapped. The distance in kilometres and journey times by car and public transport between each medical school and its teaching practices was estimated using Transport Direct (www.transportdirect.info). The postcodes of every practice in the UK were obtained from the UK's health departments. All 33 UK medical schools responded; 4392 practices contributed to teaching, with a median (minimum-maximum) of 142 (17-385) practices per school. The median (minimum-maximum) distance between a school and a teaching practice was 28 km (0-1421 km), 41 (0:00-23:26) minutes' travel by car and 1 hour 12 (0:00-17:29) minutes' travel by public transport. All teaching practices were accessible by public transport in one school and 90-99% were in a further four schools; 24 schools had >20% of practices that were inaccessible by public transport. The 4392 undergraduate teaching general practices are widely distributed and potentially any practice, no matter how isolated, could contribute to undergraduate education. However, this is, at the price of a considerable travel burden. © British Journal of General Practice 2014.
Full Text Available Kunj Patel, Omar El Tokhy Faculty of Medicine, Imperial College London, London, UKWe read with great interest the study by Frost et al1 which highlights the importance of scenario-based teaching (SBT of clinical communication in medical undergraduate pediatrics teaching. SBT involves students navigating a storyline based around a complex problem, running in parallel with case-based learning. We were impressed by the results of the SBT program at Cardiff University School of Medicine. As medical students currently on our pediatric rotation at Imperial College London, we have experienced at first hand the benefits of SBT. Throughout the placement, it continues to help us tackle the complexities which arise when communicating with children and their families. We have noted its particular benefit in breaking bad news to families. Without effective teaching on this particular scenario, a failure to grasp this skill could exacerbate patient and parent concerns. Much like the authors of this study highlight,1 we believe specific teaching on communication skills should be a mandatory part of medical undergraduate education at every institution. Imperial College School of Medicine has developed a similar teaching style which has been unparalleled in its benefit to us during our pediatric rotation. Although there is scant literature available specifically addressing communicating with children and parents at undergraduate level, the use of SBT throughout undergraduate medical teaching should not be underestimated.

Considering the heightened importance of evidence-based practice in healthcare settings, incorporating evidence-based practice into the nursing curriculum, especially in baccalaureate programs is essential because this is a first step to prepare students for their professional role as an RN, and the undergraduate nursing students are the ones who will spend the most time with patients at their bedside providing direct care. Teaching evidence-based practice at the undergraduate level, however, can be challenging. Creative and enjoyable teaching strategies are instrumental in order to promote students' engagement and learning about evidence-based practice. This paper describes useful strategies for teaching evidence-based practice in an undergraduate nursing research course. Copyright © 2017 Elsevier Inc. All rights reserved.

Medico-legal tasks are not exclusive to forensic medical experts -any physician may face medico-legal issues in his career. Hence, the practice of medicine requires education in legal issues. In Saudi Arabia, there are 30 universities with medical colleges, but we do not know how they teach undergraduate forensic medicine and medico-legal issues. The aim of this study was to discover undergraduate training courses in forensic medicine in Saudi universities. We conducted a cross-sectional study involving all colleges of medicine in Saudi Arabia. A structured, self-administered questionnaire containing 13 items relating to the undergraduate forensic medicine course was distributed. Out of a total of 30 universities, 27 universities responded. Of these 27 universities, 16 (59.26%) teach forensic medicine to undergraduate medical students, and 11 (40.74%) do not teach forensic medicine in their undergraduate curriculum. Of the 27 universities that responded, none has a department of forensic medicine. Eleven universities that do not teach forensic medicine have no forensic medicine unit/division or faculty at all. Forensic medicine belongs to the pathology department in 11 universities, while it belongs to different departments in five universities. There is variation in teaching methods, years where the course is taught and length of the course. Practical and morgue visits take place in 7/16 (43.8%) universities, while 9/16 (56.3%) universities only teach the theoretical aspects of forensic medicine. All 16 universities teach forensic medicine only to medical students and do not teach it to students in other colleges such as dentistry and nursing. © The Author(s) 2016.

This research project investigates communication between international teaching assistants and their undergraduate students in university-level chemistry labs. During the fall semester, introductory-level chemistry lab sections of three experienced non-native speaking teaching assistants and their undergraduate students were observed. Digital audio and video recordings documented fifteen hours of lab communication, focusing on the activities and interactions in the first hour of the chemistry laboratory sessions. In follow-up one-on-one semi-structured interviews, the participants (undergraduates, teaching assistants, and faculty member) reviewed interactions and responded to a 10-item, 7-point Likert-scaled interview. Interactions were classified into success categories based on participants' opinions. Quantitative and qualitative data from the observations and interviews guided the analysis of the laboratory interactions, which examined patterns of conversational listening. Analysis of laboratory communication reveals that undergraduates initiated nearly two-thirds of laboratory communication, with three-fourths of interactions less than 30 seconds in duration. Issues of gender and topics of interaction activity were also explored. Interview data identified that successful undergraduate-teaching assistant communication in interactive science labs depends on teaching assistant listening comprehension skills to interpret and respond successfully to undergraduate questions. Successful communication in the chemistry lab depended on the coordination of visual and verbal sources of information. Teaching assistant responses that included explanations and elaborations were also seen as positive features in the communicative exchanges. Interaction analysis focusing on the listening comprehension demands placed on international teaching assistants revealed that undergraduate-initiated questions often employ deixis (exophoric reference), requiring teaching assistants to

Graduate teaching assistants (GTAs) play a prominent role in chemistry laboratory instruction at research based universities. They teach almost all undergraduate chemistry laboratory courses. However, their role in laboratory instruction has often been overlooked in educational research. Interest in chemistry GTAs has been placed on training and their perceived expectations, but less attention has been paid to their experiences or their potential benefits from teaching. This work was designed to investigate GTAs' experiences in and benefits from laboratory instructional environments. This dissertation includes three related studies on GTAs' experiences teaching in general chemistry laboratories. Qualitative methods were used for each study. First, phenomenological analysis was used to explore GTAs' experiences in an expository laboratory program. Post-teaching interviews were the primary data source. GTAs experiences were described in three dimensions: doing, knowing, and transferring. Gains available to GTAs revolved around general teaching skills. However, no gains specifically related to scientific development were found in this laboratory format. Case-study methods were used to explore and illustrate ways GTAs develop a GTA self-image---the way they see themselves as instructors. Two general chemistry laboratory programs that represent two very different instructional frameworks were chosen for the context of this study. The first program used a cooperative project-based approach. The second program used weekly, verification-type activities. End of the semester interviews were collected and served as the primary data source. A follow-up case study of a new cohort of GTAs in the cooperative problem-based laboratory was undertaken to investigate changes in GTAs' self-images over the course of one semester. Pre-semester and post-semester interviews served as the primary data source. Findings suggest that GTAs' construction of their self-image is shaped through the

We developed a hands-on laboratory exercise for undergraduate students in which they can build and manipulate a neuron equivalent circuit. This exercise uses electrical circuit components that resemble neuron components and are easy to construct. We describe the methods for creating the equivalent circuit and how to observe different neuron properties through altering the structure of the equivalent circuit. We explain how this hands-on laboratory activity allows for the better understanding of this fundamental neuroscience concept. At the conclusion of this laboratory exercise, undergraduate students will be able to apply the principles of Ohm's law, cable theory with regards to neurons, and understand the functions of resistance and capacitance in a neuron.

Undergraduate students learn about mammalian cell culture applications in introductory biology courses. However, laboratory modules are rarely designed to provide hands-on experience with mammalian cells or teach cell culture techniques, such as trypsinization and cell counting. Students are more likely to learn about cell culture using bacteria or yeast, as they are typically easier to grow, culture, and manipulate given the equipment, tools, and environment of most undergraduate biology laboratories. In contrast, the utilization of mammalian cells requires a dedicated biological safety cabinet and rigorous antiseptic techniques. For this reason, we have devised a laboratory module and method herein that familiarizes students with common cell culture procedures, without the use of a sterile hood or large cell culture facility. Students design and perform a time-efficient inquiry-based cell viability experiment using HeLa cells and tools that are readily available in an undergraduate biology laboratory. Students will become familiar with common techniques such as trypsinizing cells, cell counting with a hemocytometer, performing serial dilutions, and determining cell viability using trypan blue dye. Additionally, students will work with graphing software to analyze their data and think critically about the mechanism of death on a cellular level. Two different adaptations of this inquiry-based lab are presented-one for non-biology majors and one for biology majors. Overall, these laboratories aim to expose students to mammalian cell culture and basic techniques and help them to conceptualize their application in scientific research.

Undergraduate courses in biopsychology, neuroscience, and physiology often include laboratory exercises that examine responses to stimulation of the sympathetic nervous system with measurements of heart rate, blood pressure, or galvanic skin levels (sweat response). A newer bioindicator of the sympathetic nervous system is salivary alpha-amylase (sAA) measured with a colorimetic enzyme assay. Undergraduate students successfully measured a rise in sAA due to the stress of giving a class presentation (n=13). Students were enthusiastic to measure a physiological response to a real-life anxiety-producing situation. We describe potential difficulties in the assay and our adaptations to the manufacturer's protocol to make it more feasible in the undergraduate setting.

Full Text Available Introduction: In India, medical undergraduates think that statistics is difficult to understand. Often, it is taught just before final assessment examination using didactic lectures, with little use of medical examples and less focus on application. Hence, we prepared interactive, participatory sessions for teaching biostatistics to medical undergraduate. Methods: The sessions were delivered by a facilitator. It had clearly specified objectives and teaching learning strategies. A needs assessment was done by interviewing the students who had undergone traditional biostatistics teaching methodology. Specific learning objectives for the sessions were finalized using the Delphi technique and review of University syllabus. Two trained Community Medicine faculties designed the lesson plans ‘backwards’ from desired outcome to content, teaching/learning strategies, assessment and evaluation process (Outcomes-based lesson planning. Forty, third-semester (Para-clinical phase of the second year medical undergraduates undertook these seven teaching sessions. The session followed adult learning principles and included group discussions, games and reflections. We evaluated the impact of the sessions using in-depth interviews, retrospective post-then-preself- assessment and a pre-announced written test. Results: With traditional statistics teaching methodology, students perceived it as a standalone subject and were not interested in statistics. Students who underwent the sessions commented that the sessions were enjoyable, interesting, and participatory and more than %90 of them felt they were engaged throughout the session. They also narrated various instances where they could apply the biostatistics learning. In the post-then-pre-assessment median post-session scores for all the objectives were significantly higher (p <0.050. Conclusion: Use of interactive, participatory sessions for teaching biostatistics to medical undergraduates resulted in a

Experiential learning is a useful teaching tool in the undergraduate community psychology classroom. In addition to improving student outcomes, experiential learning is particularly relevant for community psychology, as it aligns with several core values of the field and can prompt not only student learning, but also civic engagement, social justice, and community betterment. In this article, we provide an overview of the themed issue on "Experiential Teaching Practices in Undergraduate Community Psychology." The issue contains a variety of experiential teaching examples that fall into three clusters: (a) individual and group service-learning exercises; (b) using community experiences to augment in-class learning outside of a service-learning context; and (c) ways of having students draw on prior out-of-class or in-class community experiences to increase student understanding.
Multiple intelligences theory has only recently entered the teaching and learning dialogue in education and research. It is argued that despite the rhetoric of a student centred approach, nurse education remains wedded to conventional teaching approaches, which fail to engage with the individual and unwittingly silence the student's voice. This study examines the concept of Multiple Intelligences (MI) and outlines Gardner's contention that the brain functions using eight intelligences, which can be employed to improve learning at an individual level.

In physiological education, blended course formats (integration of face-to-face and online instruction) can facilitate increased student learning, performance, and satisfaction in classroom settings. There is limited evidence on the effectiveness of using blending course formats in laboratory settings. We evaluated the impact of blended learning on student performance and perceptions in an undergraduate exercise physiology laboratory. Using a randomized, crossover design, four laboratory topics were delivered in either a blended or traditional format. For blended laboratories, content was offloaded to self-paced video demonstrations (∼15 min). Laboratory section 1 (n = 16) completed blended laboratories for 1) neuromuscular power and 2) blood lactate, whereas section 2 (n = 17) completed blended laboratories for 1) maximal O2 consumption and 2) muscle electromyography. Both sections completed the same assignments (scored in a blinded manner using a standardized rubric) and practicum exams (evaluated by two independent investigators). Pre- and postcourse surveys were used to assess student perceptions. Most students (∼79%) watched videos for both blended laboratories. Assignment scores did not differ between blended and traditional laboratories (P = 0.62) or between sections (P = 0.91). Practicum scores did not differ between sections (both P > 0.05). At the end of the course, students' perceived value of the blended format increased (P physiology laboratories provided an alternative method for delivering content that was favorably perceived by students and did not compromise student performance.

Educating undergraduates about current genetic testing and genomics can involve novel and creative teaching practices. The higher education literature describes numerous pedagogical approaches in the laboratory designed to engage science and liberal arts students. Often these experiences involve students analyzing their own genes for various polymorphisms, some of which are associated with disease states such as an increased risk for developing cancer. While the literature acknowledges possible ethical ramifications of such laboratory exercises, authors do not present recommendations or rubrics for evaluating whether or not the testing is, in fact, ethical. In response, we developed a laboratory investigation and discussion which allowed undergraduate science students to explore current DNA manipulation techniques to isolate their p53 gene, followed by a dialogue probing the ethical implications of examining their sample for various polymorphisms. Students never conducted genotyping on their samples because of ethical concerns, so the discussion served to replace actual genetic testing in the class. A basic scientist led the laboratory portion of the assignment. A genetic counselor facilitated the discussion, which centered around existing ethical guidelines for clinical genetic testing and possible challenges of human genotyping outside the medical setting. In their final papers, students demonstrated an understanding of the practice guidelines established by the genetics community and acknowledged the ethical considerations inherent in p53 genotyping. Given the burgeoning market for personalized medicine, teaching undergraduates about the psychosocial and ethical dimensions of human gene testing seems important and timely, and introduces an additional role genetic counselors can play in educating consumers about genomics.

Since the early 1990s there has been a burgeoning interest in global health teaching in undergraduate medical curricula. In this article we trace the evolution of this teaching and present recommendations for how the discipline might develop in future years. Undergraduate global health teaching has seen a marked growth over the past ten years, partly as a response to student demand and partly due to increasing globalization, cross-border movement of pathogens and international migration of health care workers. This teaching has many different strands and types in terms of topic focus, disciplinary background, the point in medical studies in which it is taught and whether it is compulsory or optional. We carried out a survey of medical schools across the world in an effort to analyse their teaching of global health. Results indicate that this teaching is rising in prominence, particularly through global health elective/exchange programmes and increasing teaching of subjects such as globalization and health and international comparison of health systems. Our findings indicate that global health teaching is moving away from its previous focus on tropical medicine towards issues of more global relevance. We suggest that there are three types of doctor who may wish to work in global health - the 'globalised doctor', 'humanitarian doctor' and 'policy doctor' - and that each of these three types will require different teaching in order to meet the required competencies. This teaching needs to be inserted into medical curricula in different ways, notably into core curricula, a special overseas doctor track, optional student selected components, elective programmes, optional intercalated degrees and postgraduate study. We argue that teaching of global health in undergraduate medical curricula must respond to changing understandings of the term global health. In particular it must be taught from the perspective of more disciplines than just biomedicine, in order to reflect

Abstract Undergraduate biochemistry laboratory courses often do not provide students with an authentic research experience, particularly when the express purpose of the laboratory is purely instructional. However, an instructional laboratory course that is inquiry‐ and research‐based could simultaneously impart scientific knowledge and foster a student's research expertise and confidence. We have developed a year‐long undergraduate biochemistry laboratory curriculum wherein students determine, via experiment and computation, the function of a protein of known three‐dimensional structure. The first half of the course is inquiry‐based and modular in design; students learn general biochemical techniques while gaining preparation for research experiments in the second semester. Having learned standard biochemical methods in the first semester, students independently pursue their own (original) research projects in the second semester. This new curriculum has yielded an improvement in student performance and confidence as assessed by various metrics. To disseminate teaching resources to students and instructors alike, a freely accessible Biochemistry Laboratory Education resource is available at http://biochemlab.org. © 2015 The Authors Biochemistry and Molecular Biology Education published by Wiley Periodicals, Inc. on behalf of International Union of Biochemistry and Molecular Biology, 43(4):245–262, 2015.

A growing revolution is under way in the teaching of introductory science to undergraduates. It is driven by concerns about American competitiveness as well as results from recent educational research, which explains why traditional teaching approaches in large classes fail to reach many students and provides a basis for designing improved methods of instruction. Discipline-based educational research in the life sciences and other areas has identified several innovative promising practices and demonstrated their effectiveness for increasing student learning. Their widespread adoption could have a major impact on the introductory training of biology students.
Articles from the primary scientific literature can be a valuable teaching tool in undergraduate classrooms. At Colgate University, I emphasize selected research articles in an upper-level undergraduate course in planetary sciences. In addition to their value for conveying specific scientific content, I find that they also impart larger lessons which are especially apt in planetary sciences and allied fields. First, because of the interdisciplinary nature of planetary sciences, students discover that contributions to outstanding problems may arrive from unexpected directions, so they need to be aware of the multi-faceted nature of scientific problems. For instance, after millennia of astrometric attempts, the scale of the Solar System was determined with extraordinary precision with emerging radar technology in the 1960's. Second, students learn the importance of careful work, with due attention to detail. After all, the timescales of planetary formation are encoded in systematic isotopic variations of a few parts in 10,000; in students' own experiences with laboratory data they might well overlook such a small effect. Third, students identify the often-tortuous connections between measured and inferred quantities, which corrects a common student misconception that all quantities of interest (e.g., the age of a meteorite) can be measured directly. Fourth, research articles provide opportunities for students to practice the interpretation of graphical data, since figures often represent a large volume of data in succinct form. Fifth, and perhaps of greatest importance, by considering the uncertainties inherent in reported data, students come to recognize the limits of scientific understanding, the extent to which scientific conclusions are justified (or not), and the lengths to which working scientists go to mitigate their uncertainties. These larger lessons are best mediated by students' own encounters with the articles they read, but require instructors to make

Full Text Available From an analysis of a learning model based on the theory of information processing four hypothesis were developed for improving the design of laboratory courses. Three of these hypotheses concerned specific procedures to minimise the load on students' working memories (or working spaces and the fourth hypothesis was concerned with the value of mini-projects in enhancing meaningful learning of the knowledge and skills underpinning the set experiments. A three-year study of a first year undergraduate chemistry laboratory course at a Scottish university has been carried out to test these four hypotheses. This paper reports the results of the study relevant to the three hypotheses about the burden on students' working spaces. It was predicted from the learning model that the load on students working space should be reduced by appropriate changes to the written instructions and the laboratory organisation and by the introduction of prelab-work and prelab-training in laboratory techniques. It was concluded from research conducted over the three years period that all these hypothesised changes were effective both in reducing the load on students' working spaces and in improving their attitudes to the laboratory course.

Full Text Available Concerns persist regarding the lack of promotion of students’ scientific inquiry processes in undergraduate physics laboratories. The consensus in the literature is that, especially in the early years of undergraduate physics programs, students’ laboratory work is characterized by recipe type, step-by-step instructions for activities where the aim is often confirmation of an already well-established physics principle or concept. In response to evidence reflecting these concerns at their university, the authors successfully secured funding for this study. A mixed-method design was employed. In the 2011/2012 academic year baseline data were collected. A quantitative survey, the Undergraduate Physics Laboratory Learning Environment Scale (UPLLES was developed, validated, and used to explore students’ perceptions of their physics laboratory environments. Analysis of data from the UPLLES and from interviews confirmed the concerns evident in the literature and in a previous evaluation of laboratories undertaken in 2002. To address these concerns the activities that students were to perform in the laboratory section of the course/s were re/designed to engage students in more inquiry oriented thinking and activity. In Fall 2012, the newly developed laboratory activities and tutorials, were implemented for the first time in PHYS124; a first year course. These changes were accompanied by structured training of teaching assistants and changes to the structure of the evaluation of students’ laboratory performance. At the end of that term the UPLLES was administered (n = 266 and interviews with students conducted (n = 16 to explore their perceptions of their laboratory environments. Statistically significant differences (p<.001 between the students in the PHYS 124 classes of 2011/2012 and 2012/2013 across all dimensions were found. Effect sizes of 0.82 to 1.3, between the views of students in the first semester physics classes of 2011/2012 and 2012

Full Text Available Biochemistry learning demands skills to obtaining and interpreting the experimental data. In a classical model of teaching involve student’s hands-on participation. However this model is expensive, not safe and should be carried out in a short and limited time course. With utilization of educational software these disadvantages are overcome, since the virtual activity could be realized at free full access, and is a tool for individual study. The aim of the present work is to present educational software focused on a virtual for undergraduate student of biochemistry courses. The software development was performed with the help of concept maps, ISIS Draw, ADOBE Photoshop and FLASH MX Program applied on the subject salivary amylase. It was possible to present the basic methodologies for study of the kinetic of enzyme. The substrate (starch consumption was determinate by iodine reaction, while the products (reducing sugars formation was evaluated by cupper-alkaline reaction. The protocols of the virtual experiments are present verbally as well as a subtitle. A set of exercises are disposable, which allowed an auto evaluation and a review of the subject. The experimental treatment involved the presentation of this hypermedia for Nutrition and Dentistry/UFSC undergraduate students as a tool for better comprehension of the theme and promoted the understanding of the kinetic of enzyme.

in 2008, the British Geriatrics Society (BGS) developed the Recommended Undergraduate Curriculum in Geriatric Medicine. This was subsequently mapped to the second edition of Tomorrows' Doctors (TD2, 2003). Following the publication of the third edition of Tomorrow's Doctors in 2009 (TD3), the mapping exercise was repeated to verify the extent to which the updated General Medical Council recommendations supported teaching in ageing and geriatric medicine. we analysed TD3 and identified 48 aspects of its general guidance that were relevant to the teaching of medicine for older people. We then mapped these to the 2009 BGS curriculum. the BGS curriculum was supported in full by TD3. However, learning outcomes relating to the interpretation and conduct of research in TD3 had no corresponding outcomes in the BGS curriculum. the BGS curriculum for medical undergraduates continues to provide a specific and complete list of learning objectives, all of which could help to operationalise the general statements made in TD3 with relation to ageing and geriatric medicine. Learning outcomes in research in frail older patients have been added following this mapping exercise.

Peer assisted learning (PAL) has been shown in undergraduate programmes to be as effective as learning from instructors. PAL is a shared experience between two learners often with one being more senior to the other but usually both are studying within the same discipline. Interprofessional education occurs when two or more professionals learn with, from and about each other. Benefits of PAL in an interprofessional context have not been previously explored. As part of a final year education unit, midwifery students at Monash University developed workshops for second year undergraduate paramedic students. The workshops focused on care required during and after the birth of the baby. To investigate the benefits of an interprofessional PAL for both midwifery and paramedic students. Data for this project were obtained by both quantitative and qualitative methods. Questionnaires were distributed to both cohorts of students to explore experiences of peer teaching and learning. Results were analysed using Statistical Package for Social Sciences (SPSS). Focus groups were conducted separately with both cohorts of students and transcripts analysed using a thematic approach. Response rates from the midwifery and paramedic students were 64.9% and 44.0% respectively. The majority of students regardless of discipline enjoyed the interprofessional activity and wanted more opportunities in their curricula. After initial anxieties about teaching into another discipline, 97.3 (n = 36) of midwifery students thought the experience was worthwhile and personally rewarding. Of the paramedic students, 76.9% (n = 60) reported enjoying the interaction. The focus groups supported and added to the quantitative findings. Both midwifery and paramedic students had a new-found respect and understanding for each other's disciplines. Midwifery students were unaware of the limited knowledge paramedics had around childbirth. Paramedic students admired the depth of knowledge displayed by the midwifery

Clustered regularly interspaced short palindromic repeats (CRISPRs) represent a novel type of adaptive immune system found in eubacteria and archaebacteria. CRISPRs have recently generated a lot of attention due to their unique ability to catalog foreign nucleic acids, their ability to destroy foreign nucleic acids in a mechanism that shares some similarity to RNA interference, and the ability to utilize reconstituted CRISPR systems for genome editing in numerous organisms. In order to introduce CRISPR biology into an undergraduate upper-level laboratory, a five-week set of exercises was designed to allow students to examine the CRISPR status of uncharacterized Escherichia coli strains and to allow the discovery of new repeats and spacers. Students started the project by isolating genomic DNA from E. coli and amplifying the iap CRISPR locus using the polymerase chain reaction (PCR). The PCR products were analyzed by Sanger DNA sequencing, and the sequences were examined for the presence of CRISPR repeat sequences. The regions between the repeats, the spacers, were extracted and analyzed with BLASTN searches. Overall, CRISPR loci were sequenced from several previously uncharacterized E. coli strains and one E. coli K-12 strain. Sanger DNA sequencing resulted in the discovery of 36 spacer sequences and their corresponding surrounding repeat sequences. Five of the spacers were homologous to foreign (non-E. coli) DNA. Assessment of the laboratory indicates that improvements were made in the ability of students to answer questions relating to the structure and function of CRISPRs. Future directions of the laboratory are presented and discussed. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(3):262-269, 2017. © 2016 The International Union of Biochemistry and Molecular Biology.

Organ procurement and transplant improve health outcomes among patients with organ failure. Although many strategies have been developed to overcome the organ shortage, the worldwide rates of organ donation remain suboptimal. The lack of commitment to the health care mission of organ donation and the limited expertise of health care professionals reflect 2 major barriers to organ procurement and raise the need to teach organ procurement to health care professionals early during their undergraduate education. To accommodate the various available curricular models and to develop a homogeneous and equitable teaching methodology irrespective of the adopted design, an early step is to set clear goals and objectives for an organ procurement program. Outcomes should be matched to different academic levels and tailored to the duration of each medical and nursing curriculum. In all cases, hands-on experience leads to a better understanding of the topic, especially with the advent of simulation techniques that may be useful for training as well as testing purposes. An effective program finally requires that attainment of objectives and outcomes are systematically tested using proper evaluation tools that adequately pair with the curricular design. In conclusion, organ procurement teaching should adopt a systematic evidence-based approach that simultaneously contributes to medical and nursing education and improves organ donation rates.

With the aid of a National Science Foundation teaching equipment grant, replacement of dated equipment and the implementation of new experiments have upgraded the University of Michigan Department of Nuclear Engineering's 25-yr-old plasma laboratory course. The course teaches seniors and first-year graduate students methods of plasma production as well as plasma diagnostics. This paper describes four new experiments as well as the highlights of some of the equipment upgrades. The plasma lab course has introduced three new diagnostic techniques and one new plasma generation experiment in the past two years. They are (a) probe measurements of the electron energy distribution function, (b) laser/Schlieren photos of shock waves produced by a pulsed plasma, (c) a laser deflection technique for determining hot gas densities, and (d) capacitively coupled radio-frequency plasma generation
Diving education and diving science and technology may be a useful tool in teaching physics in non–physics-oriented High School courses. In this paper we present an activity which combines some simple theoretical aspects of fluid statics, fluid dynamics and gas behavior under pressure with diving experience, where the swimming pool and the sea are used as a laboratory. This topic had previously been approached in a pure experimental way in school laboratory, but some particular experiments became much more attractive and meaningful to the students when they could use their bodies to perform them directly in water. The activity was carried out with groups of students from Italian High School classes in different situations.

Many experiences in high school and undergraduate laboratories are well-tested cookbook recipes that have already been designed to yield optimal results; the well-known synthesis of aspirin is such an example. In this project for advanced placement or second-year high school chemistry students, students mimic the process development in industrial laboratories by investigating the effect of varying conditions in the synthesis of aspirin. The class decides on criteria that should be explored (quantity of catalyst, temperature of reaction, etc.). The class is then divided into several teams with each team assigned a variable to study. Each team must submit a proposal describing how they will explore the variable before they start their study. After data on yield and purity has been gathered and evaluated, students discuss which method is most desirable, based on their agreed-upon criteria. This exercise provides an opportunity for students to review many topics from the course (rate of reaction, limiting reagents, Beer's Law) while participating in a cooperative exercise designed to imitate industrial process development.

Three-dimensional models, photogrammetry and remote sensing are increasingly common techniques used in structural analysis. We have found that using drones and Lidar on undergraduate field trips has piqued interest in fieldwork, provided data for follow-up laboratory exercises, and inspired undergraduates to attempt 3D modelling in independent mapping projects. The scale of structures visible in cliff and sea shore exposures in South Wales is ideal for using drones to capture images for 3D models. Fault scarps in the South Wales coalfield were scanned by Lidar and drone. Our experience suggests that the drone data were much easier to acquire and process than the Lidar data, and adequate for most teaching purposes. In the lab, we used the models to show the structure in 3D, and as the basis for an introduction to geological modelling software. Now that tools for photogrammetry, drones, and processing software are widely available and affordable, they can be readily integrated into teaching. An additional benefit from the images and models is that they may be used for exercises that can be substituted for fieldwork to achieve some (but not all) of the learning outcomes in the case that field access is prevented.

BACKGROUND: International experience has demonstrated that the medical profession is becoming less dominated by men. This "feminization of medicine" has been a topic of much debate in the medical literature. As the gender ratio in the profession changes, it is likely that a greater proportion of undergraduate education will be provided by women. Whether this shift away from the male-dominated provision of medical education will have an effect on undergraduate education is unknown. PURPOSE: The aim of this research was to clarify whether there are differences between the attitudes and practices of male and female junior doctors regarding the practice of undergraduate teaching. METHOD: A survey methodology among a cohort of nonconsultant hospital doctors in a major Irish teaching hospital was utilized. The overall response rate was 93%. The cohort held a positive attitude toward teaching undergraduates, and the majority were actively engaged in this activity. Doctors of both genders expressed a willingness to undertake teacher training. RESULTS: There were no significant differences between the genders regarding the self-reported quantity of teaching provided to undergraduates. Male doctors perceived themselves as more confident educators when compared to female doctors, but this is likely to reflect cohort demographics in which a greater proportion of male doctors were more senior. CONCLUSIONS: This study demonstrates that male and female doctors have similar attitudes toward, and practices in, voluntary undergraduate teaching. As a result, any gender shift in medicine is unlikely to result in a significant change in junior doctors\\' attitudes toward undergraduate medical education.

This paper describes an exercise in a Systems and Behavioral Neuroscience with Laboratory class, an introductory laboratory class taken by Barnard College students majoring in a wide range of academic topics. The study took place over three weeks, allowing students to assess the effects of caffeine on motor stimulation in laboratory rats. The within-subject design involved injecting rats with three different caffeine doses and measuring five different motor outputs in a standard open field. Students completed four different assignments related to this study, demonstrating acquisition of the stated learning goals. This lab exercise allowed students to learn about basal ganglia neural circuitry and stimulant pharmacology, to work directly with an animal model, and to generate enough data to perform statistical analyses. Course evaluations suggest that students liked learning about caffeine, a stimulant many of them have personal experience consuming. They also expressed appreciation for working with rats and for learning how to analyze data. This study can easily be implemented at most undergraduate institutions under minimal cost. The wide-ranging effects of caffeine also permit for flexibility in experimental design, allowing instructors and students options for different avenues of investigation.

In this study we challenged 18 undergraduate physics students to develop four written scientific arguments across four physics labs: 1) gravity-driven acceleration, 2) conservation of mechanical energy, 3) conservation of linear momentum and 4) boyle's law, in a mechanics and thermodynamics laboratory course. We evaluated quality of the written scientific arguments developed by the participants using the Claim, Evidence, Reasoning and Rebuttal (CERR) rubric. The results indicate that while students developed adequate scientific explanations that summarized the findings of their experiments, they experienced unique difficulties in using a persuasive and critical discourse in their written arguments. Students experienced the most difficulty in considering alternative explanations in formulating their written scientific arguments. We elaborate on the implications of these findings for teaching physics laboratories and assessing students' learning in physics laboratories. We especially focus on the importance of framing in helping students to appropriate the epistemic norms of science in writing scientific arguments.

Full Text Available Synthetic biology offers an ideal opportunity to promote undergraduate laboratory courses with research-style projects, immersing students in an inquiry-based program that enhances the experience of the scientific process. We designed a semester-long, project-based laboratory curriculum using synthetic biology principles to develop a novel sensory device. Students develop subject matter knowledge of molecular genetics and practical skills relevant to molecular biology, recombinant DNA techniques, and information literacy. During the spring semesters of 2014 and 2015, the Synthetic Biology Laboratory Project was delivered to sophomore genetics courses. Using a cloning strategy based on standardized BioBrick genetic “parts,” students construct a “reporter plasmid” expressing a reporter gene (GFP controlled by a hybrid promoter regulated by the lac-repressor protein (lacI. In combination with a “sensor plasmid,” the production of the reporter phenotype is inhibited in the presence of a target environmental agent, arabinose. When arabinose is absent, constitutive GFP expression makes cells glow green. But the presence of arabinose activates a second promoter (pBAD to produce a lac-repressor protein that will inhibit GFP production. Student learning was assessed relative to five learning objectives, using a student survey administered at the beginning (pre-survey and end (post-survey of the course, and an additional 15 open-ended questions from five graded Progress Report assignments collected throughout the course. Students demonstrated significant learning gains (p < 0.05 for all learning outcomes. Ninety percent of students indicated that the Synthetic Biology Laboratory Project enhanced their understanding of molecular genetics. The laboratory project is highly adaptable for both introductory and advanced courses.

Background Undergraduate orthodontic teaching has been focused on developing an understanding of occlusal development in an effort to equip practitioners to make appropriate referrals for specialist-delivered care. However, there is a growing interest among general dentists in delivering more specialised treatments, including short-term orthodontic alignment. This study aimed to assess the levels of knowledge of occlusal problems among final year undergraduate dental students, as well as their interest in various orthodontics techniques and training.Methods A 36-item electronic questionnaire was sent to all final year undergraduate students in four dental institutes in the UK (Barts and the London, Kings College London, Cardiff and Dundee). The questionnaire explored satisfaction with undergraduate orthodontic teaching; students' perception of knowledge, based on General Dental Council learning outcomes; perceptions of the need for specialist involvement in the management of dental problems; interest in further training in orthodontics; and potential barriers to undertaking specialist training.Results The overall response rate was 66% (239/362). The majority of students (84.1%) were aware of GDC guidance in terms of undergraduate teaching. Students reported a preference for case-based and practical teaching sessions in orthodontics, with less interest in lectures or problem-based learning approaches. A high percentage were interested in further teaching in interceptive orthodontics (60.3%) and fixed appliance therapy (55.7%). Further training including specialist orthodontic training (36.4%), Invisalign (59%) and Six Month Smiles (41%) courses appealed to undergraduates. Levels of student debt, course fees and geographical issues were seen as potential barriers to formal, specialist training pathways.Conclusions Satisfaction with undergraduate orthodontic teaching is high and interest in further training, including specialist training pathways, continues to be high

The development of Compton Scattering experiment, studied by undergraduate students of the Medical Physics course at the Universidade Estadual de Campinas (UNICAMP), takes place in the Medical Physics Teaching Laboratory, belonging to the Gleb Wataghin Physics Institute (IFGW/UNICAMP). The experiment consists of a fixed 137 Cs radioactive source, with current activity of 610.5 MBq and a scintillation detector that turns around the center of the system whose function is to detect the scattered photons spectrum by a scatter object (target). The 137 Cs source is stored in a lead shield with a collimating window for the gamma radiation emitted with energy of 0.662 MeV. This source is exposed only when an attenuation barrier protecting the collimating window is opened. The process of opening and closing the attenuation barrier may deliver a radiation dose to users when done manually. Considering the stochastic harmful effects of ionizing radiation, the goal of this project was to develop an automatic exposure system of the radioactive source, in order to reduce the radiation dose received during the Compton Scattering experiment. The developed system is micro controlled and performs standard operating routines, responding to emergencies. Furthermore, an electromagnetic lock enables quick closing of the barrier by gravity, in case of interruption of the electrical current circuit. Besides reducing the total dose to lab users, the system adds more security to the routine, since it limits the access to the radioactive source and prevents accidental exposure. (author)

It will always remain a goal of an undergraduate biochemistry laboratory course to engage students hands-on in a wide range of biochemistry laboratory experiences. In 2006, our research group initiated a project for in silico prediction of enzyme function based only on the 3D coordinates of the more than 3800 proteins "of unknown function" in the Protein Data Bank, many of which resulted from the Protein Structure Initiative. Students have used the ProMOL plugin to the PyMOL molecular graphics environment along with BLAST, Pfam, and Dali to predict protein functions. As young scientists, these undergraduate research students wanted to see if their predictions were correct and so they developed an approach for in vitro testing of predicted enzyme function that included literature exploration, selection of a suitable assay and the search for commercially available substrates. Over the past two years, a team of faculty members from seven different campuses (California Polytechnic San Luis Obispo, Hope College, Oral Roberts University, Rochester Institute of Technology, St. Mary's University, Ursinus College, and Purdue University) have transferred this approach to the undergraduate biochemistry teaching laboratory as a Course-based Undergraduate Research Experience. A series of ten course modules and eight instructional videos have been created (www.promol.org/home/basil-modules-1) and the group is now expanding these resources, creating assessments and evaluating how this approach helps student to grow as scientists. The focus of this manuscript will be the logistical implications of this transition on campuses that have different cultures, expectations, schedules, and student populations. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(5):426-436, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

Full Text Available The objective of this study was to investigate the reactions of undergraduate and graduate students to the teaching procedures used in semipresential classes. This exploratory study was performed with a quantitative approach at a public university, with undergraduate and graduate students who had completed semipresential classes on health promotion education. Among the 19 evaluated teaching procedures, 15 (78.9% did not show any statistically significant differences between the two academic levels. The means and medians for most variables, for both undergraduate (78.9% and graduate (89.5% students, were above 7 in a scale ranging between 0 (awful and 10 (excellent. Therefore, it is concluded that both groups showed similar reactions to the teaching procedures and gave satisfactory opinions in this regard. Understanding these aspects can support designing class disciplines that use teaching procedures that are adequate to university students.

The Reformed Teaching Observation Protocol (RTOP; Swada, et al., 2002) has been used by a trained team of On the Cutting Edge (CE) observers to characterize the degree of student-centered teaching in US college and university geoscience classrooms. Total RTOP scores are derived from scores on 25 rubric items used to characterize teaching practices in categories of lesson design, content delivery, student-instructor and student-student interactions. More than 200 classroom observations have been completed by the RTOP team in undergraduate courses at a variety of US institution types (e.g., community colleges, research universities). A balanced mix of early career, mid-career, and veteran faculty are included, and the study examines class sizes ranging from small (80 students). Observations are limited to one class session and do not include laboratories or field activities. Data include RTOP scores determined by a trained observer during the classroom observation and an online survey in which the observed instructors report on their teaching practices. RTOP scores indicate that the observed geoscience classes feature varying degrees of student-centered teaching, with 30% of observed classes categorized as teacher-centered (RTOP scores ≤30), 45% of observed classes categorized as transitional classrooms (RTOP scores 31-49) and 25% are student-centered (RTOP scores ≥ 50). Instructor self-report survey data and RTOP scores indicate that geoscience faculty who have participated in one or more CE professional development event and use the CE website have an average RTOP score of 49, which is significantly higher (> 15 points) than the average score of faculty who have not participated in CE events and have not used the website. Approximately 60% of student-centered classes (those with high RTOP scores) use some traditional lecture nearly every day, but are also are likely to include an in-class activity or group discussion (e.g. Think-Pair-Share). More than 50% of

Understanding instructors’ attitudes and approaches to teaching undergraduate-level quantum mechanics can be helpful in developing effective instructional tools to help students learn quantum mechanics. Here we discuss the findings from a survey in which 12 university faculty members reflected on various issues related to undergraduate-level quantum mechanics teaching and learning. Topics included faculty members’ thoughts on the goals of a college quantum mechanics course, general challenges in teaching the subject matter, students’ preparation for the course, views about foundational issues and the difficulty in teaching certain topics, reflection on their own learning of quantum mechanics when they were students versus how they teach it to their students and the extent to which they incorporate contemporary topics into their courses. The findings related to instructors’ attitudes and approaches discussed here can be useful in improving teaching and learning of quantum mechanics.

Full Text Available We report on the development of students’ ideas of probability and probability density in a University of Maine laboratory-based general education physics course called Intuitive Quantum Physics. Students in the course are generally math phobic with unfavorable expectations about the nature of physics and their ability to do it. We describe a set of activities used to teach concepts of probability and probability density. Rudimentary knowledge of mechanics is needed for one activity, but otherwise the material requires no additional preparation. Extensions of the activities include relating probability density to potential energy graphs for certain “touchstone” examples. Students have difficulties learning the target concepts, such as comparing the ratio of time in a region to total time in all regions. Instead, they often focus on edge effects, pattern match to previously studied situations, reason about necessary but incomplete macroscopic elements of the system, use the gambler’s fallacy, and use expectations about ensemble results rather than expectation values to predict future events. We map the development of their thinking to provide examples of problems rather than evidence of a curriculum’s success.

Selecting appropriate teaching and learning strategies within an overarching teaching philosophy is 1 way of influencing nursing students' self-directedness. We conducted research to compare the self-directed learning readiness and learning attributes in different years of study of undergraduate nursing students who are exposed to traditional, lecture-based learning and problem-based learning strategies. We found that readiness for self-directed learning is not dependent on the dominant teaching-learning strategy used in the nursing program.

Full Text Available We have developed and tested two linked but separable structured inquiry exercises using a set of Drosophila melanogaster GAL4 enhancer trap strains for an upper-level undergraduate laboratory methods course at Bucknell University. In the first, students learn to perform inverse PCR to identify the genomic location of the GAL4 insertion, using FlyBase to identify flanking sequences and the primary literature to synthesize current knowledge regarding the nearest gene. In the second, we cross each GAL4 strain to a UAS-CD8-GFP reporter strain, and students perform whole mount CNS dissection, immunohistochemistry, confocal imaging, and analysis of developmental expression patterns. We have found these exercises to be very effective in teaching the uses and limitations of PCR and antibody-based techniques as well as critical reading of the primary literature and scientific writing. Students appreciate the opportunity to apply what they learn by generating novel data of use to the wider research community.

Several studies have demonstrated that undergraduate students benefit from research experiences. Benefits of undergraduate research include 1) personal and intellectual development, 2) more and closer contact with faculty, 3) the use of active learning techniques, 4) creation of high expectations, 5) development of creative and problem-solving skills, 6) greater independence and intrinsic motivation to learn, and 7) exposure to practical skills. The scientific discipline also benefits, as studies have shown that undergraduates who engage in research experiences are more likely to remain science majors and finish their degree program (Lopatto, 2007). Research experiences come as close as possible to allowing undergraduates to experience what it is like to be an academic or research member of their profession working to advance their discipline. Soils form in the field, therefore, field experiences are very important in developing a complete and holistic understanding of soil science. Combining undergraduate research with field experiences can provide extremely beneficial outcomes to the undergraduate student, including increased understanding of and appreciation for detailed descriptions and data analysis as well as an enhanced ability to see how various parts of their undergraduate education come together to understand a complex problem. The experiences of the authors in working with undergraduate students on field-based research projects will be discussed, along with examples of some of the undergraduate research projects that have been undertaken. In addition, student impressions of their research experiences will be presented. Reference Lopatto, D. 2007. Undergraduate research experiences support science career decisions and active learning.

This study explores the literature in establishing the value of undergraduate peer-based healthcare ethics teaching as an educational methodology. A narrative review of the literature concerning peer-based ethics teaching was conducted. MEDLINE, EMBASE, CINAHL, SCOPUS databases, and the Cochrane Library, were systematically searched for studies of peer-based ethics or professionalism teaching. Selected studies related peer-based teaching to ethics education outcomes. Ten publications were identified. Selected studies were varied in their chosen intervention methodology and analysis. Collectively, the identified studies suggest peer-based ethics education is an effective and valued educational methodology in training healthcare professionals. One paper suggests peer-based ethics teaching has advantages over traditional didactic methods. Peer-based ethics teaching also receives positive feedback from student participants. However, the limited literature base demonstrates a clear need for more evaluation of this pedagogy. The current literature base suggests that undergraduate peer based healthcare ethics teaching is valuable in terms of efficacy and student satisfaction. We conclude that the medical community should invest in further study in order to capitalise upon the potential of peer-based ethics teaching in undergraduate healthcare education.
Full Text Available Introduction: Bedside teaching is defined as teaching in the presence of a patient, it is a vital component of medical education. The aim of this study was to evaluate the effectiveness of two methods of case based teaching (at the bedside and in the classroom in the teaching hospitals (for both undergraduates and residents of pediatrics. Methods: Thirty undergraduates and twenty pediatric residents were asked to study a topic of their curriculum from their text then pretest was taken from learners in the two levels; then either lecture with power point or case presentation or bed side discussion were conducted. One week later posttest was taken, and then evaluation of these three methods was done by a questionnaire from learners. Results: The majority of under-graduates and all of pediatric residents had evaluated case based teaching superior to bedside teaching and these two methods superior to lecture method. Conclusion: They believed that in the case based teaching they are more relaxed and have more self-esteem than at the bedside of the patients. Clinician teacher must involve patients and learners in the process of bedside teaching, by preparing a comfortable situation and by using available technolgy.

Today, more minority students are entering undergraduate programs than ever before, but they earn only 6% of all science or engineering PhDs awarded in the United States. Many studies suggest that hands-on research activities enhance students' interest in pursuing a research career. In this paper, we present a model for the implementation of laboratory research in the undergraduate teaching laboratory using a culturally relevant approach to engage students. Laboratory modules were implemented in upper-division genetics and cell biology courses using cassava as the central theme. Students were asked to bring cassava samples from their respective towns, which allowed them to compare their field-collected samples against known lineages from agricultural stations at the end of the implementation. Assessment of content and learning perceptions revealed that our novel approach allowed students to learn while engaged in characterizing Puerto Rican cassava. In two semesters, based on the percentage of students who answered correctly in the premodule assessment for content knowledge, there was an overall improvement of 66% and 55% at the end in the genetics course and 24% and 15% in the cell biology course. Our proposed pedagogical model enhances students' professional competitiveness by providing students with valuable research skills as they work on a problem to which they can relate.
As undergraduate laboratory research internships become more popular and universities devote considerable resources towards promoting them, it is important to clarify what students specifically gain through involvement in these experiences and it is important to understand their impact on the science pipeline. By examining recent findings describing the primary benefits of undergraduate research participation, along with self-efficacy theory, this study aims to provide more explanatory power to the anecdotal and descriptive accounts regarding the relationship between undergraduate research experiences and interest in continuing in science. Furthermore, this study characterizes practices that foster students' confidence in doing scientific work with detailed description and analysis of the interactions of researchers in a laboratory. Phase 1 of the study, a survey of undergraduate biology majors (n=71) at a major research university, investigates the relationships among participation in biology laboratory research internships, biology laboratory self-efficacy strength, and interest in persisting in science. Phase 2 of the study, a two-year investigation of a university biology research laboratory, investigates how scientific communities of practice develop self-efficacy beliefs. The findings suggest that participation in lab internships results in increased interest in continuing in life science/biology graduate school and careers. They also suggest that a significant proportion of that interest is related to the students' biology laboratory self-efficacy. The findings of this study point to two primary ways that undergraduate research participation might work to raise self-efficacy strength. First, university research laboratory communities can provide students with a variety of resources that scaffold them into biology laboratory mastery experiences. Second, university research laboratory communities can provide students with coping and mastery Discourse models

Anatomical education is a dynamic field where developments in the implementation of constructive, situated-learning show promise in improving student achievement. The purpose of this study was to examine the effectiveness of an individualized, technology heavy project in promoting student performance in a combined anatomy and physiology laboratory course. Mixed-methods research was used to compare two cohorts of anatomy laboratories separated by the adoption of a new laboratory atlas project, which were defined as preceding (PRE) and following the adoption of the Anatomical Teaching and Learning Assessment Study (ATLAS; POST). The ATLAS project required the creation of a student-generated, photographic atlas via acquisition of specimen images taken with tablet technology and digital microscope cameras throughout the semester. Images were transferred to laptops, digitally labeled and photo edited weekly, and compiled into a digital book using Internet publishing freeware for final project submission. An analysis of covariance confirmed that student final examination scores were improved (P project (PRE, n = 75; POST, n = 90; means ± SE; 74.9 ± 0.9 versus 78.1 ± 0.8, respectively) after controlling for cumulative student grade point average. Analysis of questionnaires collected (n = 68) from the post group suggested students identified with atlas objectives, appreciated the comprehensive value in final examination preparation, and the constructionism involved, but recommended alterations in assignment logistics and the format of the final version. Constructionist, comprehensive term-projects utilizing student-preferred technologies could be used to improve performance toward student learning outcomes. © 2014 American Association of Anatomists.

Full Text Available Undergraduate microbiology courses offer a perfect opportunity to introduce students to historical food preservation processes that are still in use today. The fermentation of vegetables, as occurs in the preparation of sauerkraut and kimchi, uses an enrichment step to select for the growth of naturally occurring lactic acid bacteria (LAB. This is an active learning exercise in which students learn a food preparation skill and basic microbiological terms such as selection and enrichment. When performed in conjunction with cultured fermentations, such as yogurt making, students can see the difference between fermentations by naturally occurring microorganisms versus inoculated microorganisms. Additionally, this exercise introduces students to concepts of food safety, intrinsic factors influencing microbial growth such as pH, and cultural uses of fermentation to preserve locally available foods.

Full Text Available Context: Undergraduate teaching in dermatology comprises didactic lectures and clinical classes. Integrated modular teaching is a novel approach, which integrates basic sciences with dermatology in the form of a module. Further the module also incorporates various teaching modalities, which facilitate active participation from students and promotes learning. The pre- and post-test values showed the effectiveness of the integrated module. The students feedback was encouraging. Aims: The aim of this study was to determine the acceptance and opinion of undergraduate students regarding integrated modular teaching as a new teaching aid in dermatology. Settings and Design: This was a descriptive study. Varied teaching methodologies involving multiple disciplines were undertaken in six major undergraduate topics in dermatology for seventh and eighth semester students. Materials and Methods: A total of six modules were conducted over a period of 12 months for students of seventh and eighth semesters. The topics for the various modules were sexually transmitted diseases, acquired immunodeficiency syndrome, oral ulcers, leprosy, connective tissue disorders and psoriasis. Faculty members from different disciplines participated. Pre- and post-test were conducted before and after the modules respectively to gauge the effectiveness of the modules. Results: It was found that almost every student had a better score on the posttest as compared to the pretest. General feedback obtained from the students showed that all of them felt that modular teaching was a more interesting and useful teaching learning experience than conventional teaching. Conclusions: Integrated modular teaching can be an effective adjunct in imparting theoretical and practical knowledge to the students. Further, various teaching methodologies can be used in integrated modules effectively with active student participation. Thus integrated modular teaching addresses two important issues in

This paper overviews the curricula of nuclear medicine (NM) undergraduate training in 34 Central and Eastern European (CEE) and 37 European Union (EU) medical faculties. The data show enormous variation in the number of hours devoted to nuclear medicine, varying between 1-2 to 40 hours and highly differentiated concepts/ideas of nuclear medicine training in particular countries. In most EU countries this teaching is integrated with that of radiology or clinical modules, also with training in clinical physiology. In many CEE countries teaching and testing of NM are independent, although integration with other teaching modules is frequent. The paper discusses the differences in particular approaches to nuclear medicine teaching. (author)

Background Patients make a crucial contribution to undergraduate medical education. Although a national resource is available for patients participating in research, none is as yet available for education. Aim This study aimed to explore what information patients would like about participation in general practice based undergraduate medical education, and how they would like to obtain this information. Design and setting Two focus groups were conducted in London-based practices involved in both undergraduate and postgraduate teaching. Method Patients both with and without teaching experience were recruited using leaflets, posters, and patient participation groups. An open-ended topic guide explored three areas: perceived barriers that participants anticipated or had experienced; patient roles in medical education; and what help would support participation. Focus groups were audiorecorded, transcribed, and analysed thematically. Results Patients suggested ways of professionalising the teaching process. These were: making information available to patients about confidentiality, iterative consent, and normalising teaching in the practice. Patients highlighted the importance of relationships, making information available about their GPs’ involvement in teaching, and initiating student–patient interactions. Participants emphasised educational principles to maximise exchange of information, including active participation of students, patient identification of student learner needs, and exchange of feedback. Conclusion This study will inform development of patient information resources to support their participation in teaching and access to information both before and during general practice based teaching encounters.

Reform agendas for practice in undergraduate chemistry are moving curriculum beyond traditional behaviorist teaching strategies to include constructivist approaches, for extending student learning beyond simple mastery of chemistry content (Bunce & Robinson, 1997; Lagowski, 1998; Herron & Nurrenburn, 1999). Yet implementing new strategies requires assessment of their benefit to learning. This study was undertaken to provide a formal and formative evaluation of the curricula in General and Organic chemistry laboratory courses, which are structured with both Traditional expository lab exercises, and a cooperative inquiry exercise called the Open Ended Project. Using a mixed-methodological case study framework, the primary goal of the research was to determine how the inclusion of these teaching strategies impacts student learning in the areas of Academic Achievement and Affective Learning from the perspective of the students enrolled in these lab classes. The findings suggest that the current curriculum structure of including both Traditional Instruction and the Open Ended Project does address students' Academic Achievement and Affective Learning. However, students perceived that these curriculum components each contributed differently to their learning. For Academic Achievement, Traditional Experiments and the Project had a positive impact on students' operational skills, such as how to use and choose lab techniques for performing or designing experiments, as well as their conceptual learning, such as understanding concepts, and relating those concepts during data analysis. Yet for Affective Learning, such as students' sense of confidence, accomplishment, and engagement, the Project, which has a cooperative learning element, had a positive impact on student learning, while Traditional Experiments, which do not have a cooperative learning element, had a moderate negative impact. The findings point to Cooperative Learning as the key element, which makes the positive
BACKGROUND AND OBJECTIVES: Teaching is an important responsibility of non-consultant hospital doctors. In Ireland, specialist registrars (SpRs) in anaesthesia are contractually obliged to teach medical students, other doctors and nurses. Both medical students and fellow non-consultant hospital doctors attribute between 30 and 40% of their knowledge gain to non-consultant hospital doctors. METHODS: We carried out a confidential telephone survey of anaesthetic SpRs in Ireland regarding their current teaching practices and the perceptions of their role as undergraduate teachers. All the SpRs currently working in clinical practice in Ireland were eligible. RESULTS: Fifty-five of the 79 (70%) SpRs responded to the questionnaire. Only 7 (12.7%) of the respondents said they had been well trained as a teacher. The majority of the respondents stated that they would attend a learning-to-teach course\\/workshop if one was available, and felt that such a course would improve their ability as a teacher. Only 8 (14.5%) agreed that adequate emphasis is placed on commitment to teaching in the assessment of SpRs, both by individual departments and by the College of Anaesthetists. Anaesthetic SpRs in Ireland spend a considerable amount of time each day teaching undergraduate medical students, the majority (68.9%) stated that they had inadequate time to prepare for teaching. CONCLUSION: The majority of the respondents stated that they enjoy teaching, feel that they play an important role in undergraduate teaching but have inadequate time to prepare for teaching. An adequate emphasis is not placed on their commitment to teaching.

Full Text Available Safety awareness in the laboratory is essential to reduce occupational risks. This study was conducted to determine the students’ safety awareness in a Physics laboratory. This study determined the student perception towards safety awareness by factors of gender and college from which students are enrolled. A sum of 324 students enrolled in Physics10 (Mechanics and Heat and Physics11 (Electricity and Magnetism in the Mindanao University of Science and Technology (MUST were randomly selected as survey respondents. A modified survey questionnaire was used as research instrument. The results show that the students had positive level of safety awareness and perceived positively on the preventive measures to reduce laboratory risk. Further, regardless of gender students enrolled in Physics 10 were more positively aware towards safety awareness than students enrolled in Physics 11. Similarly, a variation among the students perception towards safety awareness from the College of Engineering and Architecture (CEA and College of Industrial and Information Technology (CIIT occurred. Overall, present findings indicate a need to introduce laboratory safety awareness in Physics classes.

Haloperoxidase enzymes are of interest for basic and applied bioscientists because of their increasing importance in pharmaceutical industry and environmental cleanups. In a guided inquiry-based laboratory experiment for life-science, agricultural science, and health science undergraduates, the bromoperoxidase from a red seaweed was used to brominate bromophenol red, a novel starting substrate. Substrate and enzyme concentration dependence of this enzyme-catalyzed reaction as followed colorimetrically yielded initial rates of reaction that the students compared with those of their peers. The students worked as collaborative groups partially designing their own experiments and carrying them out. In performing the laboratory experiment, they were minimally guided by the instructor and teaching assistants. To engage the students before the laboratory, a short activity involving the enzyme-induced color change was carried out. At the end of the laboratory session, student groups discussed their results in front of the class and reached their own conclusions. Most students had better understanding of important concepts in enzyme kinetics and showed good attitude toward the overall student-centered laboratory exercise.

This study presents a review of the current state of research on teaching quantum mechanics in secondary and lower undergraduate education. A conceptual approach to quantum mechanics is being implemented in more and more introductory physics courses around the world. Because of the differences between the conceptual nature of quantum mechanics and classical physics, research on misconceptions, testing, and teaching strategies for introductory quantum mechanics is needed. For this review, 74 articles were selected and analyzed for the misconceptions, research tools, teaching strategies, and multimedia applications investigated. Outcomes were categorized according to their contribution to the various subtopics of quantum mechanics. Analysis shows that students have difficulty relating quantum physics to physical reality. It also shows that the teaching of complex quantum behavior, such as time dependence, superposition, and the measurement problem, has barely been investigated for the secondary and lower undergraduate level. At the secondary school level, this article shows a need to investigate student difficulties concerning wave functions and potential wells. Investigation of research tools shows the necessity for the development of assessment tools for secondary and lower undergraduate education, which cover all major topics and are suitable for statistical analysis. Furthermore, this article shows the existence of very diverse ideas concerning teaching strategies for quantum mechanics and a lack of research into which strategies promote understanding. This article underlines the need for more empirical research into student difficulties, teaching strategies, activities, and research tools intended for a conceptual approach for quantum mechanics.

We have designed a three-week experiment that can complement any microbiology course, to teach main geomicrobiology concepts for non-geology majors. One of the most difficult concepts for non-geology majors to comprehend is how bacteria serve as a platform for different mineralization reactions. In our three-week laboratory practice, students learn the main principles and conditions required for an induced bacterial mineralization. Upon completion of the laboratory experience, students will: 1) learn how microbial-induced mineralization (such as calcium carbonate formation) is affected by differential media and growth conditions; 2) understand how bacterial physiology affects any induced in situ or in vitro mineralization; 3) comprehend how growing conditions and bacterial physiologies interrelate, resulting in differential crystal formation. The teaching-learning process was assessed using a pre-/posttest with an increase from 26% to 76% in the number of positive answers from the students. We also measured the students' proficiency while conducting specific technical tasks, revealing no major difficulties while conducting the experiments. A final questionnaire was provided with satisfactory evaluations from the students regarding the organization and content of the practices. 84-86% of the students agreed that the exercises improved their knowledge in geomicrobiology and would like to attend similar laboratories in the future. Such response is the best indicator that the laboratory practice can be implemented in any undergraduate/graduate microbiology course to effectively teach basic geomicrobiology concepts to non-geology majors.

Full Text Available BACKGROUND: In Germany, family physicians (FPs are increasingly needed to participate in undergraduate medical education. Knowledge of FPs' motivation to teach medical students in their practices is lacking. PURPOSE: To describe a novel questionnaire that assesses the motivation of FPs to teach undergraduates in their practices and to show the results of a subsequent survey using this instrument. METHODS: The questionnaire was developed based on a review of the literature. Previously used empirical instruments assessing occupational values and motivation were included. A preliminary version was pretested in a pilot study. The resulting 68-item questionnaire was sent to 691 FPs involved in undergraduate medical education. Reliability was assessed and subgroups were analyzed with regard to differences in motivation. RESULTS: A total of 523 physicians in n = 458 teaching practices participated (response rate 75.7%. 'Helping others' and 'interest' were revealed as the predominant motives. Responses showed a predominantly intrinsic motivation of the participating FPs. Their main incentives were an ambition to work as a medical preceptor, to generally improve undergraduate education and to share knowledge. Material compensation was of minor importance. Time restraints were indicated as a barrier by some FPs, but were not a general concern. CONCLUSION: German FPs involved in medical education have altruistic attitudes towards teaching medical students in their practices. Motivational features give an important insight for the recruitment of FP preceptors as well as for their training in instructional methods.

Because content saturation is a growing concern, as reflected in the nursing literature, the content taught in undergraduate nursing curricula should be critically examined. The purpose of this descriptive cross-sectional research was to determine and analyze the physical assessment content currently taught in undergraduate nursing programs. A total of 198 individuals teaching in undergraduate nursing programs completed a Web-based survey. Of the 122 skills included on the survey, 81% were reportedly being taught in most of the nursing programs. Total scores for 18 systems-based assessment categories were significantly different among associate and baccalaureate nursing programs in all but three categories: assessment of integument, breast, and female genitals. Previous research has shown that nurses use less than 25% of these same skills regularly in clinical practice, regardless of their educational preparation. Findings from this research raise questions about the breadth to which physical examination content should be taught in undergraduate nursing education.
It is well known that several reports on the common educational problems of nuclear chemistry have been prepared by certain groups of experts from time to time. According to very important statements in these reports, nuclear chemistry and related courses generally do not take sufficient importance in undergraduate chemistry curricula and it was generally proposed that nuclear chemistry and related courses should be introduced into undergraduate chemistry curricula at universities worldwide. Starting from these statements, an ideal program in an undergraduate chemistry curriculum was proposed to be introduced into the undergraduate chemistry program at the Department of Chemistry, Ege University, in Izmir, Turkey during the regular updating of the chemistry curriculum. Thus, it has been believed that this Department of Chemistry has recently gained an ideal teaching program in the field of nuclear chemistry and its applications in scientific, industrial, and medical sectors. In this contribution, the details of this program will be discussed. (author)

The new French law about clinical laboratory medicine, the requirements of the ISO/CEI 15189 standard, the numerous abilities expected from the medical laboratory technologists and their involvement in blood bank management has led the working group "Recherche et démarche qualité" of the French Society of Blood Transfusion to initiate an inventory of blood transfusion teaching syllabus for medical laboratory technology students and to propose transfusion medicine teaching guidelines. Seven worksheets have been established for that purpose including red blood cell antigen typing and antibody screening, blood sampling in immunohaematology, automation, clinical practices, blood products, blood delivery and haemovigilance. These guidelines aim at contributing to the harmonization of transfusion medicine teaching and at providing objective elements to the medical laboratory managers regarding the practical and theoretical skills of theirs collaborators.

This study tests the hypothesis that undergraduates who peer teach genetics will have greater understanding of genetic and molecular biology concepts as a result of their teaching experiences. Undergraduates enrolled in a non-majors biology course participated in a service-learning program in which they led middle school (MS) or high school (HS) students through a case study curriculum to discover the cause of a green tomato variant. The curriculum explored plant reproduction and genetic principles, highlighting variation in heirloom tomato fruits to reinforce the concept of the genetic basis of phenotypic variation. HS students were taught additional activities related to mole-cular biology techniques not included in the MS curriculum. We measured undergraduates' learning outcomes using pre/postteaching content assessments and the course final exam. Undergraduates showed significant gains in understanding of topics related to the curriculum they taught, compared with other course content, on both types of assessments. Undergraduates who taught HS students scored higher on questions specific to the HS curriculum compared with undergraduates who taught MS students, despite identical lecture content, on both types of assessments. These results indicate the positive effect of service-learning peer-teaching experiences on undergraduates' content knowledge, even for non-science major students. © 2014 H. E. Chrispeels et al.

Capillary electrophoresis (CE), although a powerful analytical tool, has found only limited application in undergraduate laboratory study. In an effort to expose freshman and sophomore chemistry students to this technique, thereby giving them practical instrumental experience early in their careers, we propose to use CE in the analysis of student-synthesized acetylsalicylic acid (ASA). The synthesis of ASA from salicylic acid (SA) is a routine undergraduate laboratory, although students rarely have the opportunity to test the purity of their product. The CE method described herein provides students with a method to test purity and yield of their product and to determine the effect of aging on their sample. CE can accomplish this in a short period of time, with minimal disruption to the regular laboratory curriculum. Optimized separation conditions, limits of detection, and linear range for ASA and SA are also given.

computer-aided learning (CAL) is increasingly used to deliver teaching, but few studies have evaluated its impact on learning within geriatric medicine. We developed and implemented CAL packages on falls and continence, and evaluated their effect on student performance in two medical schools. traditional ward based and didactic teaching was replaced by blended learning (CAL package combined with traditional teaching methods). Examination scores were compared for cohorts of medical students receiving traditional learning and those receiving blended learning. Control questions were included to provide data on cohort differences. in both medical schools, there was a trend towards improved scores following blended learning, with a smaller number of students achieving low scores (P learning was associated with improvement in student examination performance, regardless of the setting or the methods adopted, and without increasing teaching time. Our findings support the use of CAL in teaching geriatric medicine, and this method has been adopted for teaching other topics in the undergraduate curriculum.

Personality assessment is a crucial component of clinical practice, and the training and proficiency criteria to develop competence are complex and multifaceted. Like many advanced topics, the field of personality assessment would benefit from early exposure in undergraduate classroom settings. This research evaluates how an undergraduate personality course can be enhanced through 2 enrichment activities (self-assessments and a personality project). Students completed several self-assessments of their personality and wrote a comprehensive and integrative personality assessment about themselves. Results demonstrated that these activities increased interest in personality assessment, deepened understanding of course material, and promoted student growth and self-exploration. We discuss the benefits of these enrichment activities for the student, instructor, and field of personality science.

The development and implementation of a scientific outreach activity comes with a number of challenges. A successful outreach event must match the sophistication of content to the audience, be engaging, expand the knowledge base for participants, and be inclusive for a diverse audience. Ideally, a successful event will also convey the importance of scientific outreach for future scientists and citizens. In this paper, we present a simple, hands-on guide to a scientific outreach event targeted to kindergarten learners. This activity also pursued a second goal: the inclusion of undergraduate students in the development and delivery of the event. We provided a detailed set of four activities, focusing on the blind Mexican cavefish, which were enthusiastically received by kindergarten audiences. The engagement of undergraduate students in the development of this activity encouraged public outreach involvement and fostered new scientific and communication skills. The format of the outreach event we describe is flexible. We provide a set of guidelines and suggestions for adapting this approach to other biological topics. The activity and approach we describe enables the implementation of effective scientific outreach, using active learning approaches, which benefits both elementary school learners and undergraduate students.

This article presents results of an exploratory qualitative study examining gains in empathy and social justice beliefs among undergraduate nursing students. As undergraduate nursing education provides the foundation for future forensic nurses, developing successful methods to increase beliefs and behaviors of social empathy and social justice among nursing students will have a beneficial effect on the specialty of forensic nursing. As such, a team of nursing researchers explored the effects of a poverty simulation on the social empathy and social justice beliefs held by undergraduate students. The research team conducted an exploratory qualitative study of student reflective journals. Using an inductive interpretive process, the researchers performed a content analysis of student responses. The researchers identified three constitutive patterns and eight supporting themes as reflected in the students' reflective journals after participation in poverty simulation sessions. This research study found that, when nursing students participate in poverty simulation experiences, they gain an increased understanding of the vulnerability and complexities of living in poverty and are motivated to both advocate for patients and become change agents. Such increases in social empathy and promotion of social justice will inevitably positively affect their future practice and inform their development as forensic nurses.

Field observations and laboratory measurements are great ways to engage students and spark students' interests in science. Typically these observations are separated from rigorous classroom teaching. Here we assessed the potential of integrating teaching and research in the field and laboratory setting in both US and abroad and worked with students without strong science background to utilize simple laboratory equipment and various environmental sensors to conduct innovative projects. We worked with students in Namibia and two local high school students in Indianapolis to conduct leaf potential measurements, soil nutrient extraction, soil infiltration measurements and isotope measurements. The experience showed us the potential of integrating teaching and research in the field setting and working with people with minimum exposure to modern scientific instrumentation to carry out creative projects.
Applied bioinformatics skills are becoming ever more indispensable for biologists, yet incorporation of these skills into the undergraduate biology curriculum is lagging behind, in part due to a lack of instructors willing and able to teach basic bioinformatics in classes that don't specifically focus on quantitative skill development, such as statistics or computer sciences. To help undergraduate course instructors who themselves did not learn bioinformatics as part of their own education and are hesitant to plunge into teaching big data analysis, a module was developed that is written in plain-enough language, using publicly available computing tools and data, to allow novice instructors to teach next-generation sequence analysis to upper-level undergraduate students. To determine if the module allowed students to develop a better understanding of and appreciation for applied bioinformatics, various tools were developed and employed to assess the impact of the module. This article describes both the module and its assessment. Students found the activity valuable for their education and, in focus group discussions, emphasized that they saw a need for more and earlier instruction of big data analysis as part of the undergraduate biology curriculum.

Full Text Available Bringing discovery-based research into undergraduate laboratory courses increases student motivation and learning gains over traditional exercises that merely teach technique or demonstrate well-documented phenomena. Laboratory experiences are further enhanced when they are designed to challenge student perspectives on topics relevant to their lives. To this end, a laboratory module on antibiotics and hormones, which are generally discussed in the context of human health, was developed for students to explore the multifaceted roles of antibiotics and hormones in nature (e.g. interspecies communication via reading primary scientific literature and performing discovery-based experiments. The main objective of this module was to increase the general biological literacy of students as determined by their ability to connect the Five Core Concepts of Biological Literacy (American Association for the Advancement of Science, Vision and Change in Undergraduate Education: A Call to Action, 2011 to the topics “hormones” and “antibiotics” in pre- and postmodule surveys. After discussing unpublished research findings, cell biology students performed experiments demonstrating that: 1 fungi may promote fern growth via hormone production, 2 novel bacterial isolates in the genus Streptomyces produce antifungal compounds, and 3 subinhibitory antibiotic concentrations may enhance soil bacterial growth. The third finding provided evidence supporting a hypothesis framed in a scientific article that students read and discussed. Student perspectives on premodule surveys focused on roles of hormones and antibiotics in the human body (e.g. development, fighting infection, but their broadened postmodule perspectives encompassed the roles of these molecules in organismal communication and possibly the evolution of multicellularity.

Western blotting is an important, modern technique for transferring proteins from a gel onto nitrocellulose or other suitable support and then detecting a protein of interest using antibodies. We have developed an experiment and optimized the conditions for the undergraduate laboratory. The experiment can be done quickly using an electrophoretic blotter or more cheaply using passive transfer. This experiment allows the student to learn valuable procedures currently used in biochemistry and other biological sciences.

In this article, the results of a mixed-methods study integrating the use of simulations in a nursing theory course in order to assess students' perceptions of self-efficacy for nursing practice are presented. Nursing students in an intervention group were exposed to a combination of lecture and simulation, and then asked to rate their perceptions of self-efficacy, satisfaction and effectiveness of this combined teaching and learning strategy. Based on Bandura's (1977, 1986) theory of self-efficacy, this study provides data to suggest that students' self-confidence for nursing practice may be increased through the use of simulation as a method of teaching and learning. Students also reported higher levels of satisfaction, effectiveness and consistency with their learning style when exposed to the combination of lecture and simulation than the control group, who were exposed to lecture as the only method of teaching and learning.

Bridging Geosciences to the future generations in interesting and interactive ways are challenging for lecturers and teachers. In the past, one-way 'classic' face-to-face teaching method has been used as the only alternative for undergraduate's Marine Geology class in Padjadjaran University, Indonesia. Currently, internet users in Indonesia have been increased significantly, among of them are young generations and students. The advantage of the internet as a teaching method in Geosciences topic in Indonesia is still limited. Here we have combined between the classic and the online method for undergraduate teaching. The case study was in Marine Geology class, Padjadjaran University, with 70 students as participants and 2 instructors. We used Edmodo platform as a primary tool in our teaching and Dropbox as cloud storage. All online teaching activities such as assignment, quiz, discussion and examination were done in concert with the classic one with proportion 60% and 40% respectively. We found that the students had the different experience in this hybrid teaching method as shown in their feedback through this platform. This hybrid method offers interactive ways not only between the lecturers and the students but also among students. Classroom meeting is still needed to expose their work and for general discussion.Nevertheless, the only problem was the lack of internet access in the campus when all our students accessing the platform at the same time.

Peer-assisted learning (PAL) has become increasingly popular over recent years with many medical schools now formally incorporating peer-teaching programs into the curriculum. PAL has a sound evidence base with benefit to both peer-teacher and peer-learner. Aside from in teaching delivery, empowering students to develop education in its broadest sense has been much less extensively documented. Five case studies with supportive evaluation evidence illustrate the success of a broad range of peer-led projects in the undergraduate medical curriculum, particularly where these have been embedded into formal teaching practices. These case studies identify five domains of teaching and support of learning where PAL works well: teaching and learning, resource development, peer-assessment, education research and evaluation and mentoring and support. Each case offers ways of engaging students in each domain. Medical students can contribute significantly to the design and delivery of the undergraduate medical program above and beyond the simple delivery of peer-assisted "teaching". In particular, they are in a prime position to develop resources and conduct research and evaluation within the program. Their participation in all stages enables them to feel involved in course development and education of their peers and ultimately leads to an increase in student satisfaction.
Full Text Available This paper discusses how Linux clustering and virtual machine technologies can improve undergraduate students' hands-on experience in operating systems laboratories. Like similar projects, SOFTICE relies on User Mode Linux (UML to provide students with privileged access to a Linux system without creating security breaches on the hosting network. We extend such approaches in two aspects. First, we propose to facilitate adoption of Linux-based laboratories by using a load-balancing cluster made of recycled classroom PCs to remotely serve access to virtual machines. Secondly, we propose a new approach for students to interact with the kernel code.

Caenorhabditis elegans is one of the most important model organisms in the study of biology. It is ideal for laboratory teaching due to its short life cycle and low cost. It enriches the teaching content and can motivate students' interest of learning. In this article, we have shown cased C. elegans for the observation of life cycle and mating, as well as the investigation of single nucleotide polymorphism (SNP) and RNA interfere. In addition, we also discuss the details of the experimental design, basic requirement, preparations and related information. We conclude that C. elegans can be used as the experimental materials for teaching college laboratory courses, such as genetic, cell biology, model biology and developmental biology.

Good communication skills are essential for an optimal doctor-patient relationship, and also contribute to improved health outcomes. Although the need for training in communication skills is stated as a requirement in the 1997 Graduate Medical Education Regulations of the Medical Council of India, formal training in these skills has been fragmentary and non-uniform in most Indian curricula. The Vision 2015 document of the Medical Council of India reaffirms the need to include training in communication skills in the MBBS curriculum. Training in communication skills needs approaches which are different from that of teaching other clinical subjects. It is also a challenge to ensure that students not only imbibe the nuances of communication and interpersonal skills, but adhere to them throughout their careers. This article addresses the possible ways of standardizing teaching and assessment of communication skills and integrating them into the existing curriculum.

To address the faculty shortage problem, schools of nursing are reexamining how they provide clinical education to undergraduate students to find ways to use faculty resources more efficiently and to maintain student enrollment. We describe a unique clinical teaching model implemented at the New York University College of Nursing. The new model currently being evaluated shifts from the traditional clinical education model, in which all clinical education is in a hospital or agency setting, to a model that substitutes high-fidelity human patient simulation for up to half of the clinical education experience. This article describes the clinical teaching model and its effects on nurse faculty capacity. Copyright 2012, SLACK Incorporated.

Practical skills are an essential part of physicians' daily routine. Nevertheless, medical graduates' performance of basic skills is often below the expected level. This review aims to identify and summarize teaching approaches of basic practical skills in undergraduate medical education which provide evidence with respect to effective students' learning of these skills. Basic practical skills were defined as basic physical examination skills, routine skills which get better with practice, and skills which are also performed by nurses. We searched PubMed with different terms describing these basic practical skills. In total, 3467 identified publications were screened and 205 articles were eventually reviewed for eligibility. 43 studies that included at least one basic practical skill, a comparison of two groups of undergraduate medical students and effects on students' performance were analyzed. Seven basic practical skills and 15 different teaching methods could be identified. The most consistent results with respect to effective teaching and acquisition of basic practical skills were found for structured skills training, feedback, and self-directed learning. Simulation was effective with specific teaching methods and in several studies no differences in teaching effects were detected between expert or peer instructors. Multimedia instruction, when used in the right setting, also showed beneficial effects for basic practical skills learning. A combination of voluntary or obligatory self-study with multimedia applications like video clips in combination with a structured program including the possibility for individual exercise with personal feedback by peers or teachers might provide a good learning opportunity for basic practical skills.

To compare the learning objectives proposed by the European Union of Medical Specialists Geriatric section (UEMS-GS) with those approved in Spain for undergraduate teaching. Learning objectives included in the European Undergraduate Curriculum in Geriatric Medicine developed by the UEMS-GS in 2013 were compared with those listed in different Spanish official documents: Boletín Oficial del Estado (BOE, Spanish State Gazette), white book on Medicine of the Spanish Accreditation Agency (ANECA), and list of learning objectives of Spanish Medical Schools. the European curriculum recommends to teach 42 competencies divided in 10 sections, while the BOE mentions 37 general competencies and some other specific competencies, and the ANECA mentions 23 generic and 34 specific competencies (similar to the 37 of the BOE), and a list of common contents in which Geriatrics is included. The BOE includes 38% of the European competencies (range 17-100% of competencies in different sections), while the ANECA includes 52% of them (range 17-100%). Spanish regulations include from one third to half of the European recommendations for Geriatrics teaching at undergraduate level. In the future, it seems advisable that official requirements in Spain should converge with European recommendations. This task should also be performed by Spanish Medical Schools.

Full Text Available Introduction: The purpose of this study was to improve communication skills and knowledge of bioethics of last year medical students doing clerkship and to evaluate the effectiveness of using workshops for this purpose from students’ point of view, in order to continue such programs in future. Methods: After Ethical approval for the study a two-day workshop on teaching effective communication skills and principles of medical ethics was planned and conducted by the department of Medical Education through multidisciplinary faculty of Foundation University Medical College, Pakistan. A total of 102 last year medical students participated in this workshop. The students were divided into 8 groups each containing 12 students. A team of pre trained facilitators for each group conducted the group activities. Teaching strategies including interactive discussions on basic principles of doctor-patient relationship, power point presentations, day to day case scenarios, video clips and presentations involving students in role plays were used. Pre and post workshop self evaluation proformas about knowledge and skills of communication and medical ethics were rated (0=none, 1=below average, 2=average, 3=above average, 4=very good, 5=excellent by the students. Results: 89 out of 102 participants returned the proformas. A significant percentage of students (%82 showed improvement in their knowledge and skills of appreciating bioethical issues like valid informed consent, patient confidentiality, end of life issues and breaking bad news by rating as “very good” after participation in the workshop. More than %70 students recommended this activity for other students. Conclusion: Teaching through interactive workshops was found to be an effective method as reflected by students’ feedback. Therefore, the program will be continued in future.

Producing qualified forensic pathological practitioners is a common difficulty around the world. In China, forensic pathology is one of the required major subspecialties for undergraduates majoring in forensic medicine, in contrast to forensic education in Western countries where forensic pathology is often optional. The enduring predicament is that the professional qualities and abilities of forensic students from different institutions vary due to the lack of an efficient forensic pedagogical model. The purpose of this article is to describe the new pedagogical model of forensic pathology at Zhongshan School of Medicine, Sun Yat-sen University, which is characterised by: (a) imparting a broad view of forensic pathology and basic knowledge of duties and tasks in future careers to students; (b) educating students in primary skills on legal and medical issues, as well as advanced forensic pathological techniques; (c) providing students with resources to broaden their professional minds, and opportunities to improve their professional qualities and abilities; and (d) mentoring students on occupational preparation and further forensic education. In the past few years, this model has resulted in numerous notable forensic students accomplishing achievements in forensic practice and forensic scientific research. We therefore expect this pedagogical model to establish the foundation for forensic pathological education and other subspecialties of forensic medicine in China and abroad.

To establish and evaluate a new approach to teach medical students how to assess brain death in patients. A total of 120 fourth-year medical students at Münster Medical School (Germany) participated in a 1-hour lecture on how to assess brain death in patients. After this lecture, students were assigned to 2 groups. One group attended an additional practical course on the evaluation of brain death and received training using a new high-fidelity simulation device. The other group did not participate in any additional training session. All students completed a questionnaire before the lecture and a second questionnaire at the conclusion of the study. For the group undergoing the additional training, the second questionnaire was completed after the additional training session. The additional practical training session significantly improved the students' performance in assessing brain death and promoted the self-assessment and motivation of the medical students. The establishment of a new practical teaching concept led to significant improvements in medical students' assessments of brain death in a practical session. These improvements in medical education could have significant implications for the clinical assessment of patients in the future. Copyright © 2015 Association of Program Directors in Surgery.

Chemistry education researchers have not adequately studied teaching and learning experiences at all levels in the undergraduate chemistry curriculum leaving gaps in discipline-based STEM education communities understanding about how the upper- division curricula works (National Research Council, 2012b; Towns, 2013). This study explored faculty approaches to teaching in upper-division physical chemistry course settings using an interview-based methodology. Two conceptualizations of approaches to teaching emerged from a phenomenographic analysis of interview transcripts: (1) faculty beliefs about the purposes for teaching physical chemistry and (2) their conceptions of their role as an instructor in these course settings. Faculty who reported beliefs predominantly centered on helping students develop conceptual knowledge and problem-solving skills in physical chemistry often worked with didactic models of teaching, which emphasized the transfer of expert knowledge to students. When faculty expressed beliefs that were more inclusive of conceptual, epistemic, and social learning goals in science education they often described more student-centered models of teaching and learning, which put more responsibilities on them to facilitate students' interactive engagement with the material and peers during regularly scheduled class time. Knowledge of faculty thinking, as evinced in a rich description of their accounts of their experience, provides researchers and professional developers with useful information about the potential opportunities or barriers that exist for helping faculty align their beliefs and goals for teaching with research-based instructional strategies.

The aim of this work was to determine the structure, mode of delivery, mode of assessment and staffing of the oral surgery undergraduate curriculum within UK dental schools. A questionnaire was distributed by e-mail in January 2006 to each of the 15 dental schools with undergraduate dental degree programmes in Ireland and the UK. Those providing feedback then met to clarify any areas as required. Thirteen completed questionnaires were returned. There were a total of 55 academics involved in the teaching of oral surgery at these 13 institutions. Over the three clinical years the mean number of clinical sessions was 51. The mean staff student ratio for supervision of forceps exodontia was 1:5. On average 51 teeth were extracted by each student in the clinical years. The mean staff student ratio for surgical extractions was 1:2. The mean number of surgical extractions for each student was 6. All schools formatively assessed competency in forceps exodontia and 9 of 13 assessed surgical extractions. Summative assessment of exodontia was done in six schools and surgical extractions in 4 of 13 schools. All 13 schools deliver teaching programmes designed to meet the requirements of the frameworks governing the central curriculum. There were, however, variations between individual schools in the content and delivery of the oral surgery clinical teaching programmes. There were dramatic variations in the numbers of academic staff involved and some institutions relied on their NHS colleagues to deliver the clinical teaching.

Ultrasonography is a non-invasive imaging modality that offers the opportunity to teach living cardiac anatomy and physiology. The objectives of this study were to assess the feasibility of integrating an ultrasound-based course into the conventional undergraduate medical teaching programme and to analyse student and teacher feedback. An ultrasound-based teaching course was implemented and proposed to all second-year medical students (n=348) at the end of the academic year, after all the conventional modules at our faculty. After a brief theoretical and practical demonstration, students were allowed to take the probe and use the ultrasound machine. Students and teachers were asked to complete a survey and were given the opportunity to provide open feedback. Two months were required to implement the entire module; 330 (95%) students (divided into 39 groups) and 37 teachers participated in the course. Student feedback was very positive: 98% of students agreed that the course was useful; 85% and 74% considered that their understanding of cardiac anatomy and physiology, respectively, was improved. The majority of the teachers (97%) felt that the students were interested, 81% agreed that the course was appropriate for second-year medical students and 84% were willing to participate to future sessions. Cardiac anatomy and physiology teaching using ultrasound is feasible for undergraduate medical students and enhances their motivation to improve their knowledge. Student and teacher feedback on the course was very positive. Copyright © 2013 Elsevier Masson SAS. All rights reserved.
Genetic drift is one of the difficulties in teaching genetics due to its randomness and probability which could easily cause conceptual misunderstanding. The “sampling error" in its definition is often misunderstood because of the research method of “sampling", which disturbs the results and causes the random changes in allele frequency. I analyzed and compared the definitions of genetic drift in domestic and international genetic textbooks, and found that the definitions containing “sampling error" are widely adopted but are interpreted correctly in only a few textbooks. Here, the history of research on genetic drift, i.e., the contributions of Wright, Fisher and Kimura, is introduced. Moreover, I particularly describe two representative articles recently published about genetic drift teaching of undergraduates, which point out that misconceptions are inevitable for undergraduates during the studying process and also provide a preliminary solution. Combined with my own teaching practice, I suggest that the definition of genetic drift containing “sampling error" can be adopted with further interpretation, i.e., “sampling error" is random sampling among gametes when generating the next generation of alleles which is equivalent to a random sampling of all gametes participating in mating in gamete pool and has no relationship with artificial sampling in general genetics studies. This article may provide some help in genetics teaching.
The author investigates relationships between instructor, peer, and self-evaluations. Undergraduate music education students each taught three micro-teaching segments. Immediately after teaching, they filled out an evaluation for themselves indicating four things they did well, one suggestion for improvement, and an effectiveness score from 1 to…

A recent forensic approach for identification of unknown biological samples is mitochondrial DNA (mtDNA) sequencing. We describe a laboratory exercise suitable for an undergraduate biochemistry course in which the polymerase chain reaction is used to amplify a 440 base pair hypervariable region of human mtDNA from a variety of "crime scene" samples (e.g., teeth, hair, nails, cigarettes, envelope flaps, toothbrushes, and chewing gum). Amplification is verified via agarose gel electrophoresis and then samples are subjected to cycle sequencing. Sequence alignments are made via the program CLUSTAL W, allowing students to compare samples and solve the "crime."

This paper presents a high accuracy method to measure gravitational acceleration in an undergraduate laboratory program. The experiment is based on water in a cylindrical vessel rotating about its vertical axis at a constant speed. The water surface forms a paraboloid whose focal length is related to rotational period and gravitational acceleration. This experimental setup avoids classical source errors in determining the local value of gravitational acceleration, so prevalent in the common simple pendulum and inclined plane experiments. The presented method combines multiple physics concepts such as kinematics, classical mechanics and geometric optics, offering the opportunity for lateral as well as project-based learning.

This document is the student manual for a third year undergraduate laboratory experiment at the University of Manchester. This project aims to measure a fundamental difference between the behaviour of matter and antimatter through the analysis of data collected by the LHCb experiment at the Large Hadron Collider. The three-body dmecays $B^\\pm \\rightarrow h^\\pm h^+ h^-$, where $h^\\pm$ is a $\\pi^\\pm$ or $K^\\pm$ are studied. The inclusive matter antimatter asymmetry is calculated, and larger asymmetries are searched for in localized regions of the phase-space.

Homologous recombination, a central concept in biology, is defined as the exchange of DNA strands between two similar or identical nucleotide sequences. Unfortunately, undergraduate students majoring in biotechnology often experience difficulties in understanding the molecular basis of homologous recombination. In this study, we developed and implemented a 12-week laboratory course for biotechnology undergraduates in which gene targeting in Streptococcus suis was used to facilitate their understanding of the basic concept and process of homologous recombination. Students worked in teams of two to select a gene of interest to create a knockout mutant using methods that relied on homologous recombination. By integrating abstract knowledge and practice in the process of scientific research, students gained hands-on experience in molecular biology techniques while learning about the principle and process of homologous recombination. The learning outcomes and survey-based assessment demonstrated that students substantially enhanced their understanding of how homologous recombination could be used to study gene function. Overall, the course was very effective for helping biotechnology undergraduates learn the theory and application of homologous recombination, while also yielding positive effects in developing confidence and scientific skills for future work in research. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(4):329-335, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

In this poster we present the main events occurred in the history of astronomy teaching in undergraduate courses existing in Brazil since the arrival of the Portuguese Royal Family in 1808 until the end of the monarchic period. In order to compose this historic outline, we mainly use didactic books, rules, decrees and laws that organized the contents offered and the careers of those in charge for the discipline. In the analyses of the used material, we searched for the presence of philosophical and scientific assumptions that may have oriented the contents of the disciplines. Comparisons with the teaching of astronomy in other countries haven't been made. We have ended showing that the teaching of astronomy, during the monarchic period, was more directed to forming engineers than astronomers. We would like to observe that the present poster doesn't aim to approach the subject in a complete and detailed way.

The breakup of a liquid jet into spherical droplets via the Rayleigh–Plateau instability is a common and fundamental part of fluid mechanics. However, teaching this instability in a laboratory setting is challenging, requiring sophisticated methods to generate and study the jet dynamics. Recently, toroidal droplets were shown to break into one or more spherical droplets in the thin-drop limit via the Rayleigh–Plateau instability. We propose a simple experimental setup to generate toroidal droplets that break up on the order of tens of seconds, allowing for easy video capture using a basic CCD camera. With this setup, it is possible to quantify the Rayleigh–Plateau instability in a pedagogical laboratory setting. In addition, the role of curvature on jet breakup can be explored using thick toroidal droplets. We envision this setup as a powerful teaching tool for one of the most fundamental fluid dynamics processes. (paper)
The apartheid ideology in South Africa had a pervasive influence on all levels of education including medical undergraduate training. The role of the health sector in human rights abuses during the apartheid era was highlighted in 1997 during the Truth and Reconciliation Commission hearings. The Health Professions Council of South Africa (HPCSA) subsequently realised the importance of medical ethics education and encouraged the introduction of such teaching in all medical schools in the country. Curricular reform at the University of Stellenbosch in 1999 presented an unparalleled opportunity to formally introduce ethics teaching to undergraduate students. This paper outlines the introduction of a medical ethics programme at the Faculty of Health Sciences from 2003 to 2006, with special emphasis on the challenges encountered. It remains one of the most comprehensive undergraduate medical ethics programmes in South Africa. However, there is scope for expanding the curricular time allocated to medical ethics. Integrating the curriculum both horizontally and vertically is imperative. Implementing a core curriculum for all medical schools in South Africa would significantly enhance the goals of medical education in the country.

Teaching and learning of forensic medicine and pathology in the undergraduate medical curriculum has been in decline for decades in the UK, and yet graduates are expected to be able to recognise, and protect, those who are most vulnerable in society - i.e. at risk of abuse or neglect - a matter highly relevant to the role of the forensic medical practitioner. When Cardiff University School of Medicine created a new 'learner-centred' undergraduate curriculum, championing case-based discussion in small groups, and earlier clinical contact, residual teaching on 'the pathology of trauma' disappeared. An opportunity to create a new course for the year 3 core curriculum, however, led to re-emergence of forensic medicine and pathology, with a focus on identification, and protection, of the 'vulnerable patient'. This paper describes the development process of the first two iterations of that course, and the influence of 'listening to the student voice'. Forensic medicine and pathology remain relevant in undergraduate medical education; effective, and ethical, safeguarding of the vulnerable is an essential 'core' skill of the modern medical graduate, and forensic medical practitioners can play an integral role in the preparation of medical students for their future clinical practice.

Development, Evaluation and Use of a Student Experience Survey in Undergraduate Science Laboratories: The Advancing Science by Enhancing Learning in the Laboratory Student Laboratory Learning Experience Survey
Barrie, Simon C.; Bucat, Robert B.; Buntine, Mark A.; Burke da Silva, Karen; Crisp, Geoffrey T.; George, Adrian V.; Jamie, Ian M.; Kable, Scott H.; Lim, Kieran F.; Pyke, Simon M.; Read, Justin R.; Sharma, Manjula D.; Yeung, Alexandra
Student experience surveys have become increasingly popular to probe various aspects of processes and outcomes in higher education, such as measuring student perceptions of the learning environment and identifying aspects that could be improved. This paper reports on a particular survey for evaluating individual experiments that has been developed over some 15 years as part of a large national Australian study pertaining to the area of undergraduate laboratories-Advancing Science by Enhancing Learning in the Laboratory. This paper reports on the development of the survey instrument and the evaluation of the survey using student responses to experiments from different institutions in Australia, New Zealand and the USA. A total of 3153 student responses have been analysed using factor analysis. Three factors, motivation, assessment and resources, have been identified as contributing to improved student attitudes to laboratory activities. A central focus of the survey is to provide feedback to practitioners to iteratively improve experiments. Implications for practitioners and researchers are also discussed.

In this paper, we propose a simple method of observing the collision-dominated Child-Langmuir law in the course of an undergraduate laboratory work devoted to studying the properties of gas discharges. To this end we employ the dc gas discharge whose properties are studied in sufficient detail. The undergraduate laboratory work itself is reduced to registering the voltage drop across the electrodes, the discharge current as well as the cathode sheath thickness. We can easily perform the measurements of all three quantities with sufficient accuracy in a laboratory equipped with vacuum pumps.

One objective was to identify and review studies on teaching medical ethics to psychiatry residents. In order to gain insights from other disciplines that have published research in this area, a second objective was to identify and review studies on teaching medical ethics to residents across all other specialties of training and on teaching medical students. PubMed, EMBASE, and PsycINFO were searched for controlled trials on teaching medical ethics with quantitative outcomes. Search terms included ethics, bioethics, medical ethics, medical students, residents/registrars, teaching, education, outcomes, and controlled trials. Nine studies were found that met inclusion criteria, including five randomized controlled trails and four controlled non-randomized trials. Subjects included medical students (5 studies), surgical residents (2 studies), internal medicine house officers (1 study), and family medicine preceptors and their medical students (1 study). Teaching methods, course content, and outcome measures varied considerably across studies. Common methodological issues included a lack of concealment of allocation, a lack of blinding, and generally low numbers of subjects as learners. One randomized controlled trial which taught surgical residents using a standardized patient was judged to be especially methodologically rigorous. None of the trials incorporated psychiatry residents. Ethics educators should undertake additional rigorously controlled trials in order to secure a strong evidence base for the design of medical ethics curricula. Psychiatry ethics educators can also benefit from the findings of trials in other disciplines and in undergraduate medical education.

Undergraduate laboratories expose students to a wide variety of topics and techniques in a limited amount of time. This can be a challenge and lead to less exposure to concepts and activities in bio-inorganic chemistry and analytical chemistry that are closely-related to biochemistry. To address this, we incorporated a new iron determination by atomic absorption spectroscopy exercise as part of a five-week long laboratory-based project on the purification of myoglobin from beef. Students were required to prepare samples for chemical analysis, operate an atomic absorption spectrophotometer, critically evaluate their iron data, and integrate these data into a study of myoglobin. © 2015 The International Union of Biochemistry and Molecular Biology.

Undergraduate Space Weather education is an important component of creating a society that is knowledgeable about space weather and its societal impacts. The space physics community has made great strides in providing academic education for students, typically physics and engineering majors, who are interested in pursuing a career in the space sciences or space weather. What is rarely addressed, however, is providing a broader space weather education to undergraduate students as a whole. To help address this gap, I have created an introductory space weather course for non-science majors, with the idea of expanding exposure to space weather beyond the typical physics and engineering students. The philosophy and methodologies used in this course will be presented, as well as the results of the first attempts to teach it. Using an approach more tailored to the non-scientist, courses such as this can be an effective means of broadening space weather education and outreach.

concerted efforts to affect policy, workload, tenure and promotion and resource issues, which are often core factors in any STEM education change process. Several systems are now connecting individual campus-based undergraduate research efforts more effectively, and tying undergraduate research to regional workforce and economic development programs. Many campus teams are moving their department and colleges toward curricular innovations that emphasize scaffolding undergraduate research throughout the undergraduate curriculum. An NSF EAGER/WIDER supplement to the CUR CCLI III award was received in October 2012 and expanded the scope of the project to include deeper study of the changes processes underway at each of the six systems and to tease out the factors that can either promote or retard expansion of undergraduate research as a teaching and learning paradigm. Lessons learned from one of the six systems, the University of Wisconsin, will be highlighted.

Full Text Available Chemotaxis, the directed movement of cells towards or away from a chemical, is both an exciting and complicated behavior observed in many bacterial species. Attempting to adequately visualize or demonstrate the chemotaxic response of bacteria in the classroom is difficult at best, with good models to illustrate the concept lacking. The BSL-1 marine bacterium Vibrio fischeri (a.k.a. Aliivibrio fischeri is easy to culture, making it an ideal candidate for experiments in an undergraduate microbiology course. A number of chemoattractants for V. fischeri have been identified, including a variety of sugars, nucleosides, and amino acids (1, 2. Below presents how the soft agar-based chemotaxis assay can be implemented in the undergraduate laboratory. As bacterial cells migrate towards one or more attractants in soft agar, students can directly observe the chemotaxic behavior of V. fischeri without the need to learn complicated techniques or use specialized equipment. Once the bands of bacterial cells are observed, the migration can then be disrupted by the addition of excess attractant to the soft agar, thereby visualizing what happens once cells are no longer in a gradient of attractant. In addition, soft agar plates lacking attractants can be used to visualize the random movements of bacterial cells that are non-chemotaxing. These exercises can be used in the microbiology laboratory to help students understand the complex behavior of bacterial chemotaxis.

Many pre-health professional programs require completion of an undergraduate anatomy course with a laboratory component, yet grades in these courses are often low. Many students perceive anatomy as a more challenging subject than other coursework, and the resulting anxiety surrounding this perception may be a significant contributor to poor performance. Well-planned and deliberate guidance from instructors, as well as thoughtful course design, may be necessary to assist students in finding the best approach to studying for anatomy. This article assesses which study habits are associated with course success and whether course design influences study habits. Surveys (n = 1,274) were administered to students enrolled in three undergraduate human anatomy laboratory courses with varying levels of cooperative learning and structured guidance. The surveys collected information on potential predictors of performance, including student demographics, educational background, self-assessment ability, and study methods (e.g., flashcards, textbooks, diagrams). Compared to low performers, high performers perceive studying in laboratory, asking the instructor questions, quizzing alone, and quizzing others as more effective for learning. Additionally, students co-enrolled in a flipped, active lecture anatomy course achieve higher grades and find active learning activities (e.g., quizzing alone and in groups) more helpful for their learning in the laboratory. These results strengthen previous research suggesting that student performance is more greatly enhanced by an active classroom environment that practices successful study strategies rather than one that simply encourages students to employ such strategies inside and outside the classroom.

Medical education and the process of teaching and learning, respectively, are constantly changing. This is induced by the pace at which knowledge, teaching methodology and its related tools are updated, the use of simulation, virtual depiction and the use of static and/or dynamic images. In this respect, X-ray images have been used in the understanding of macroanatomy ever since the beginning of the last century. Starting with the 1990s, when high-performing and relatively less costly equipment started to emerge, several experts in the field of education anticipated the huge resource that ultrasound could become in the field of medicine. The method is easy to understand, intuitive and available to anyone studying human anatomy and, subsequently, the major pathological issues during undergraduate medical studies. The present paper reviews the attempts made at using ultrasound as an educational support tool, from the first experiences in teaching anatomy (Hannover Medical School, 1996) until the recent development of an entire medical university curriculum integrating ultrasound (University of South Carolina, School of Medicine, 2006-2011). It is an exciting journey proving beyond any doubt that the method should be learned, understood and developed in medical schools from the undergraduate stage, together with the other clinical skills.

To provide oral healthcare for patients of all ages, dental welfare environments and technical aspects of dentistry have evolved and developed and dental education must also diversify. Student-centered voluntary education and establishment of a life-long self-learning environment are becoming increasingly important in the changing world of dental education. In this article, we introduce a new process for the construction of a web-mediated database containing internet-based teaching files on the normal radiological anatomy of panoramic radiographs and CT images of the oral and maxillofacial regions, as well as a system for the delivery of visual learning materials through an intra-faculty local network. This process was developed by our 5th-year undergraduate students. Animated CT scan images were produced using Macintosh Iphoto and Imovie animation software. Normal anatomical images of panoramic radiographs and CT scans were produced using Adobe Illustrator CS and Adobe Photoshop CS. The web database was constructed using Macromedia Dreamweaver MX and Microsoft Internet Explorer. This project was the basis of our participation in the Student Clinician Research Program (SCRP). At Kyushu Dental College, we developed a new series of teaching files on the web. Uploading these teaching files to the internet allowed many individuals to access the information. Viewers can easily select the area of study that they wish to examine. These processes suggest that our laboratory practice is a useful tool for promoting students' motivation and improving life-long self learning in dental radiology. We expect that many medical and dental students, practitioners and patients will be able to use our teaching files to learn about the normal radiological anatomy of the oral and maxillofacial regions.(author)

The aim of this study was to evaluate undergraduate medical student perceptions as to the value of different types of neurosurgical teaching to their general neuroscience education, delivered in the penultimate year of a U.K medical school. We surveyed penultimate-year medical students at St George's Hospital Medical School, University of London (SGUL), who were undertaking their clinical neuroscience attachment from August 2014 to July 2015. A questionnaire comprising closed Likert scale questions and an open question inviting participants to comment freely was used to assess student perception about the value of Neurosurgical sessions within their overall neuroscience education. Of the 316 students in the year we surveyed 247 (78.2%), of whom 201 responded (response rate 81.4%). On average, 82.8% of students either agreed or strongly agreed that neurosurgical teaching sessions made a valuable contribution to their learning. In particular, lectures by neurosurgeons, clinical teaching on the Glasgow Coma Scale in neuro-ITU, bedside teaching and neurosurgical clinics were considered the most beneficial. The majority of students felt the sessions improved their understanding of neurological examination, signs, and 'red-flags'. The sessions were also beneficial for learning neuro-imaging and understanding of neurosurgical emergencies. Over two thirds felt that theatre sessions were beneficial, significantly more so amongst students invited to 'scrub-in'. Students rated neurosurgical sessions highly and valued the contribution they made not only to their learning of neurosurgical conditions and emergencies, but also to their learning of general neurology and clinical neurosciences overall. Student perceived learning from theatre sessions was significantly correlated with whether or not the student had been invited to 'scrub-in'. Expert neurosurgical teaching can make a valuable, and arguably essential contribution to the undergraduate medical curriculum.
Full Text Available Abstract Background It has been proved that basic science knowledge learned in the context of a clinical case is actually better comprehended and more easily applied by medical students than basic science knowledge learned in isolation. The present study intended to validate the effectiveness of Clinically Oriented Physiology Teaching (COPT in undergraduate medical curriculum at Melaka Manipal Medical College (Manipal Campus, Manipal, India. Methods COPT was a teaching strategy wherein, students were taught physiology using cases and critical thinking questions. Three batches of undergraduate medical students (n = 434 served as the experimental groups to whom COPT was incorporated in the third block (teaching unit of Physiology curriculum and one batch (n = 149 served as the control group to whom COPT was not incorporated. The experimental group of students were trained to answer clinically oriented questions whereas the control group of students were not trained. Both the group of students undertook a block exam which consisted of clinically oriented questions and recall questions, at the end of each block. Results Comparison of pre-COPT and post-COPT essay exam scores of experimental group of students revealed that the post-COPT scores were significantly higher compared to the pre-COPT scores. Comparison of post-COPT essay exam scores of the experimental group and control group of students revealed that the experimental group of students performed better compared to the control group. Feedback from the students indicated that they preferred COPT to didactic lectures. Conclusion The study supports the fact that assessment and teaching patterns should fall in line with each other as proved by the better performance of the experimental group of students compared to the control group. COPT was also found to be a useful adjunct to didactic lectures in teaching physiology.
Full Text Available Objective: Practical skills are an essential part of physicians’ daily routine. Nevertheless, medical graduates’ performance of basic skills is often below the expected level. This review aims to identify and summarize teaching approaches of basic practical skills in undergraduate medical education which provide evidence with respect to effective students’ learning of these skills.Methods: Basic practical skills were defined as basic physical examination skills, routine skills which get better with practice, and skills which are also performed by nurses. We searched PubMed with different terms describing these basic practical skills. In total, 3467 identified publications were screened and 205 articles were eventually reviewed for eligibility. Results: 43 studies that included at least one basic practical skill, a comparison of two groups of undergraduate medical students and effects on students’ performance were analyzed. Seven basic practical skills and 15 different teaching methods could be identified. The most consistent results with respect to effective teaching and acquisition of basic practical skills were found for structured skills training, feedback, and self-directed learning. Simulation was effective with specific teaching methods and in several studies no differences in teaching effects were detected between expert or peer instructors. Multimedia instruction, when used in the right setting, also showed beneficial effects for basic practical skills learning.Conclusion: A combination of voluntary or obligatory self-study with multimedia applications like video clips in combination with a structured program including the possibility for individual exercise with personal feedback by peers or teachers might provide a good learning opportunity for basic practical skills.

In 2007, a first survey on undergraduate palliative care teaching in Switzerland has revealed major heterogeneity of palliative care content, allocation of hours and distribution throughout the 6 year curriculum in Swiss medical faculties. This second survey in 2012/13 has been initiated as part of the current Swiss national strategy in palliative care (2010 - 2015) to serve as a longitudinal monitoring instrument and as a basis for redefinition of palliative care learning objectives and curriculum planning in our country. As in 2007, a questionnaire was sent to the deans of all five medical faculties in Switzerland in 2012. It consisted of eight sections: basic background information, current content and hours in dedicated palliative care blocks, current palliative care content in other courses, topics related to palliative care presented in other courses, recent attempts at improving palliative care content, palliative care content in examinations, challenges, and overall summary. Content analysis was performed and the results matched with recommendations from the EAPC for undergraduate training in palliative medicine as well as with recommendations from overseas countries. There is a considerable increase in palliative care content, academic teaching staff and hours in all medical faculties compared to 2007. No Swiss medical faculty reaches the range of 40 h dedicated specifically to palliative care as recommended by the EAPC. Topics, teaching methods, distribution throughout different years and compulsory attendance still differ widely. Based on these results, the official Swiss Catalogue of Learning Objectives (SCLO) was complemented with 12 new learning objectives for palliative and end of life care (2013), and a national basic script for palliative care was published (2015). Performing periodic surveys of palliative care teaching at national medical faculties has proven to be a useful tool to adapt the national teaching framework and to improve the

An experimental study was performed with undergraduate nursing students in order to determine, between two methodologies, which is the best for learning standard precautions and precautions based on disease transmission mechanisms. Students in the sample are stratified by performance, with the experimental group (49 students) being exposed to self-instruction and clinical simulation on the topic of standard precautions and special precautions according to disease transmission mechanisms. Conventional classes on the same topics were provided to the control group (49 students). The experimental group showed the best performance in the multiple-choice post-test of knowledge (p=0.002) and in the assessment of essay questions (p=0.043), as well as in the evaluation of a simulated scenario, in relation to the control group. This study demonstrates that it is possible to transfer some teaching subjects on the prevention of Healthcare Associated Infections (HAIs) to self-learning by means of virtual teaching strategies with good results. This allows greater efficiency in the allocation of teachers to clinical simulation or learning situations in the laboratory, where students can apply what they have learned in the self-instruction module.

Advancing Space Sciences through Undergraduate Research Experiences at UC Berkeley's Space Sciences Laboratory - a novel approach to undergraduate internships for first generation community college students
Raftery, C. L.; Davis, H. B.; Peticolas, L. M.; Paglierani, R.
The Space Sciences Laboratory at UC Berkeley launched an NSF-funded Research Experience for Undergraduates (REU) program in the summer of 2015. The "Advancing Space Sciences through Undergraduate Research Experiences" (ASSURE) program recruited heavily from local community colleges and universities, and provided a multi-tiered mentorship program for students in the fields of space science and engineering. The program was focussed on providing a supportive environment for 2nd and 3rd year undergraduates, many of whom were first generation and underrepresented students. This model provides three levels of mentorship support for the participating interns: 1) the primary research advisor provides academic and professional support. 2) The program coordinator, who meets with the interns multiple times per week, provides personal support and helps the interns to assimilate into the highly competitive environment of the research laboratory. 3) Returning undergraduate interns provided peer support and guidance to the new cohort of students. The impacts of this program on the first generation students and the research mentors, as well as the lessons learned will be discussed.

Simulation has become a widely used and established pedagogy for teaching clinical nursing skills. Nevertheless, the evidence in favour of this pedagogical approach is weak, and more knowledge is needed in support of its use. The aim of this study was (a) to explore the experiences of undergraduate nursing students when examining knowledge, skills and competences in clinical simulation laboratories with high-fidelity patient simulators and (b) to analyse these students' learning experiences during the examination. A phenomenological approach was used, and qualitative interviews were conducted among 23 second-year undergraduate nursing students-17 women and 6 men. The findings revealed that, irrespective of whether they passed or failed the examination, it was experienced as a valuable assessment of the students' knowledge and skills. Even if the students felt that the examination was challenging, they described it as a learning opportunity. In the examination, the students were able to integrate theory with practice, and earlier established knowledge was scrutinised when reflecting on the scenarios. The examination added aspects to the students' learning that prepared them for the real world of nursing in a safe environment without risking patient safety. The study findings suggest that examinations in clinical simulation laboratories can be a useful teaching strategy in nursing education. The use of high-fidelity patient simulators made the examination authentic. The reflections and feedback on the scenario were described as significant for the students' learning. Undergraduate nursing students can improve their knowledge, understanding, competence and skills when such examinations are performed in the manner used in this study. Copyright © 2015 Elsevier Ltd.

As professionals, nurses are expected to engage in respectful relationships with clients, other health care professionals, and each other. Regulatory bodies set standards and codes of ethics for professional behavior in nursing that clearly communicate expectations for civility. However, the wealth of literature on incivility in the profession indicates that nurses often fall short of meeting these standards in their interactions with other nurses. Currently, few effective strategies exist for nurse educators to teach civility to nursing students and prepare them to engage in healthy relationships with their colleagues. This article argues for the use of virtue ethics as a philosophical framework for teaching civility to undergraduate nursing students. The pedagogical strategies proposed may help students contribute to the development of healthy workplaces. Copyright 2014, SLACK Incorporated.

It is often the case that good teachers just "intuitively" know how to teach. Whilst that may be true, there is now a greater need to understand the various processes that underpin both the ways in which a curriculum is delivered, and the way in which the students engage with learning; curricula need to be designed to meet the changing needs of our new graduates, providing new, and robust learning opportunities, and be communicated effectively to both staff and students. The aim of this document is to draw together robust and contemporaneous methods of teaching, learning and assessment that help to overcome some of the more traditional barriers within dental undergraduate programmes. The methods have been chosen to map specifically to The Graduating European Dentist, and should be considered in parallel with the benchmarking process that educators and institutions employ locally. © 2017 John Wiley & Sons A/S.

Paid summer REU experiences successfully engage undergraduate students in research and encourage them to continue to graduate school and scientific careers. However these programs only accommodate a limited number of students due to funding constraints, faculty time commitments, and limited access to needed instrumentation. At JMU, the Department of Geology and Environmental Science has embedded undergraduate research into the curriculum. Each student fulfilling a BS in Geology or a BA in Earth Science completes 3 credits of research, including a 1-credit course on scientific communication, 2 credits of research or internship, followed by a presentation of that research. Our department has successfully acquired many analytical instruments and now has an XRD, SEM/EDS, FTIR, handheld Raman, AA, ion chromatograph, and an IRMS. To give as many students as possible an overview to the scientific uses and operation methods for these instruments, we revived a laboratory methods course that includes theory and practical use of instrumentation at JMU, plus XRF sample preparation and analysis training at Virginia Tech during a 1-day field trip. In addition to practical training, projects included analytical concepts such as evaluating analytical vs. natural uncertainty, determining error on multiple measurements, signal-to-noise ratio, and evaluating data quality. State funding through the 4-VA program helped pay for analytical supplies and support for students to complete research projects over the summer or during the next academic year using instrumentation from the course. This course exemplifies an alternative path to broadening participation in undergraduate research and creating stronger partnerships between PUI's and research universities.

An online section of a face-to-face (F2F) undergraduate (bachelor's level) anatomy course with a prosection laboratory was offered in 2013-2014. Lectures for F2F students (353) were broadcast to online students (138) using Blackboard Collaborate (BBC) virtual classroom. Online laboratories were offered using BBC and three-dimensional (3D) anatomical computer models. This iteration of the course was modified from the previous year to improve online student-teacher and student-student interactions. Students were divided into laboratory groups that rotated through virtual breakout rooms, giving them the opportunity to interact with three instructors. The objectives were to assess student performance outcomes, perceptions of student-teacher and student-student interactions, methods of peer interaction, and helpfulness of the 3D computer models. Final grades were statistically identical between the online and F2F groups. There were strong, positive correlations between incoming grade average and final anatomy grade in both groups, suggesting prior academic performance, and not delivery format, predicts anatomy grades. Quantitative student perception surveys (273 F2F; 101 online) revealed that both groups agreed they were engaged by teachers, could interact socially with teachers and peers, and ask them questions in both the lecture and laboratory sessions, though agreement was significantly greater for the F2F students in most comparisons. The most common methods of peer communication were texting, Facebook, and meeting F2F. The perceived helpfulness of the 3D computer models improved from the previous year. While virtual breakout rooms can be used to adequately replace traditional prosection laboratories and improve interactions, they are not equivalent to F2F laboratories.

Near Peer teaching (NPT) is reported as an effective pedagogical approach to student learning and performance. Studies in medicine, nursing and health sciences have relied mainly on self-reports to describe its benefits, focusing on psychomotor and cognitive aspects of learning. Despite increasing research reports on peer teaching internationally, little is known about the various domains of learning used in assessment of performance and objective learning outcomes of NPT. To determine the domains of learning and assessment outcomes used in NPT in undergraduate health professional education. Quantitative systematic review was conducted in accord with the PRISMA protocol and the Joanna Briggs Institute processes. A wide literature search was conducted for the period 1990-November 2015 of fourteen databases. Grey literature was undertaken from all key research articles. Studies meeting the inclusion criteria were eligible for consideration, including measured learning outcomes of near-peer teaching in undergraduate education in nursing, medicine and health sciences. Set limitations included publications after 1990 (2015 inclusive), English language and objective learning outcomes. A quality appraisal process involving two independent reviewers was used to analyse the data. Of 212 selected articles, 26 were included in the review. Terminology was confusing and found to be a barrier to the review process. Although some studies demonstrated effective learning outcomes resulting from near-peer teaching, others were inconclusive. Studies focused on cognitive and psychomotor abilities of learners with none assessing metacognition, affective behaviours or learning outcomes from quality of understanding. The studies reviewed focused on cognitive and psychomotor abilities of learners. Even though evidence clearly indicates that metacognition and affective behaviours have direct influence on learning and performance, indicating more research around this topic is warranted

PROBLEM/PURPOSE: Baccalaureate graduates are expected to utilize research across a wide variety of practice settings. While the literature reports a variety of teaching approaches, few studies examine baccalaureate students' comprehension of research content. Teaching techniques that focus on a conceptual or theoretical approach may foster research comprehension. Therefore, the purpose of this paper is to evaluate teaching/learning outcomes of an undergraduate nursing research course designed from a conceptual or theoretical approach. Two classes of senior baccalaureate nursing students (n = 47) at a private institution, whose curriculum was based on the Roy adaptation model, were surveyed in 1990 and 1991 at the end of their undergraduate research course. The survey tool consisted of seven three-point Likert scale questions, four open-ended questions, and one unstructured comment. Findings showed that 72% strongly agreed that they would continue to read nursing articles in their practice field, 57% disagreed that they were intimidated by research language, and 55% agreed that they trusted their ability to use and utilize nursing research in practice. The most helpful learning activity was the research critique (34%) followed by group work (28%). The support of the teacher and Instructor's use of own research examples was also seen as most helpful (36%), while abstract cards (8%) were least helpful. Nonetheless, 23% requested more group activities, 13% wanted more class examples, and 11% asked for more time to comprehend definitions. Students who approached research from the perspective of a nursing conceptual framework indicated that they put the pieces of the research puzzle together by working in groups, being supported by the Instructor, and learning from a variety of teaching methods.
Full Text Available Why the need to change ? Substantial increase in the content of subject : The content of the subject has grown by at least 30 % from the time when I was an undergraduate student and we used to read the 7th edition of Preventive and Social Medicine by Park. At that time this book had only 686 pages (size of pages was at least 30 % less than now had only 16 chapters .The 21st edition of the same book has 868 pages and 23 chapters. This goes on to show that the content of subject has increased substantially. 12 weeks of clinical posting added : Medical Council of India has added 12 weeks of clinical posting to the teaching of Community Medicine similar to the postings in major clinical subjects, where in the students are available to us in small groups for approximately 3 hours everyday. In spite of the increase in subject content and the opportunity for small group teaching during postings, I personally feel that we have not been able to inspire students to learn Community Medicine with enthusiasm. Why the subject has not become much popular among under graduate students? Before going into the further details let us look at the following observations made by the WHO -SEARO expert group on “Improving the teaching of Public Health at undergraduate level in medical schools – suggested guidelines.” – Today most of the teaching in public health is carried out using didactic lectures within the ivory tower of an institution with limited exposure to the community .Public health education has to be an active process ,student centered , inquiry driven , evidence based and problem solving as well addressing the needs of the community .The role of the teacher should be to facilitate the student to acquire the competencies through field based experiential learning of public health competencies involving dedicated time for practice , receiving feedback and reflecting on its application in their future role as primary care doctors1.

Two methods of quantifying the spatial resolution of a camera are described, performed, and compared, with the objective of designing an imaging-system experiment for students in an undergraduate optics laboratory. With the goal of characterizing the resolution of a typical digital single-lens reflex (DSLR) camera, we motivate, introduce, and show agreement between traditional test-target contrast measurements and the technique of using Fourier analysis to obtain the modulation transfer function (MTF). The advantages and drawbacks of each method are compared. Finally, we explore the rich optical physics at work in the camera system by calculating the MTF as a function of wavelength and f-number. For example, we find that the Canon 40D demonstrates better spatial resolution at short wavelengths, in accordance with scalar diffraction theory, but is not diffraction-limited, being significantly affected by spherical aberration. The experiment and data analysis routines described here can be built and written in an undergraduate optics lab setting.

A major challenge in undergraduate life science curricula is the continual evaluation and development of courses that reflect the constantly shifting face of contemporary biological research. Synthetic biology offers an excellent framework within which students may participate in cutting-edge interdisciplinary research and is therefore an attractive addition to the undergraduate biology curriculum. This new discipline offers the promise of a deeper understanding of gene function, gene order, and chromosome structure through the de novo synthesis of genetic information, much as synthetic approaches informed organic chemistry. While considerable progress has been achieved in the synthesis of entire viral and prokaryotic genomes, fabrication of eukaryotic genomes requires synthesis on a scale that is orders of magnitude higher. These high-throughput but labor-intensive projects serve as an ideal way to introduce undergraduates to hands-on synthetic biology research. We are pursuing synthesis of Saccharomyces cerevisiae chromosomes in an undergraduate laboratory setting, the Build-a-Genome course, thereby exposing students to the engineering of biology on a genomewide scale while focusing on a limited region of the genome. A synthetic chromosome III sequence was designed, ordered from commercial suppliers in the form of oligonucleotides, and subsequently assembled by students into approximately 750-bp fragments. Once trained in assembly of such DNA "building blocks" by PCR, the students accomplish high-yield gene synthesis, becoming not only technically proficient but also constructively critical and capable of adapting their protocols as independent researchers. Regular "lab meeting" sessions help prepare them for future roles in laboratory science.
Full Text Available ABSTRACTThis paper reports findings from research into the benefits of integrating podcasts into a first year undergraduate module on English Language and Communication at Kingston University. As part of a Faculty teaching and learning support scheme for first year undergraduates, six podcasts were developed to improve students’ learning and study skills and to provide advice on portfolio development and presentation skills. Student learning experience through podcasts was evaluated through two focus groups, personal interviews (six students and an end of semester evaluation questionnaire (n=35. The paper describes the teaching and learning context and how the podcasts were integrated as part of the blended learning delivery. It discusses to what extent podcasts were able to achieve of the intended outcomes and the processes involved in achieving those outcomes. The findings led to development of a model for integrating podcasts in on-campus blended learning, and which can have potential applications in distance learning contexts. The model is based on three main features of podcasts identified as facilitating student learning: learner choice and flexibility offered by podcasts; tacit knowledge and experience of peers conveyed in discussions; and a sense of informality brought into formal learning.The research reported in the paper was carried out as part of a UK national research project entitled Informal Mobile Podcasting and Learning Adaptation (IMPALA with funding from the UK Higher Education Academy.

Full Text Available This article aims to be part of the ongoing discussion on the teaching of literature written in English (LWE in literature classes in undergraduate language programs. In order to do that, it shows the challenges posed by the Letras DCN (National Curriculum Guidelines for the undergraduate Language Teacher Education programs as well as the reality literature teachers face due to the reduced number of hours of literature classes assigned in course curricula and to students' limited knowledge of English. Based on the dialogical concept of language and on the possibility of cooperation between scientific trends, we present a cooperative work between DDA (Dialogical Discourse Analysis and Pragmatics, showing how consonant and dissonant they are. Besides, we present part of the analysis of Alice Walker's short story Her Sweet Jerome done by students, which, in this context of teaching LWE to students with limited knowledge of English, pointed to the possibility of Pragmatics being the first step towards a dialogical analysis of literary texts.

Behavioral assays in the undergraduate neuroscience laboratory are useful for illustrating a variety of physiological concepts. An example is homeostatic temperature regulation (thermoregulation). Many model organisms, from flies to mice, regulate internal temperatures in part by moving to suitable climates (thermotaxis). A particularly reliable method of quantifying temperature-dependent thermotactic behaviors is the two-temperature preference behavioral assay. In this preparation, an organism is free to move between two temperature-controlled surfaces, thus revealing its preferred thermal environment. Here we present the design and construction of a two-temperature preference assay chamber. The device uses Peltier-based thermoelectric modules (TECs) for heating and cooling, and is capable of precision control of temperatures from -5ºC to 60ºC. Our approach can be easily adapted for use in a variety of physiological and behavioral assays that require precise temperature control over a wide range of temperatures.

The phenomenon of electronic wave localization through disorder remains an important area of fundamental and applied research. Localization of all wave phenomena, including light, is thought to exist in a restricted one-dimensional geometry. We present here a series of experiments to illustrate, using a straightforward experimental arrangement and approach, the localization of light in a quasi-one-dimensional physical system. In the experiments, reflected and transmitted light from a stack of glass slides of varying thickness reveals an Ohm's law type behavior for small thicknesses, and evolution to exponential decay of the transmitted power for larger thicknesses. For larger stacks of slides, a weak departure from one-dimensional behavior is also observed. The experiment and analysis of the results, showing many of the essential features of wave localization, is relatively straightforward, economical, and suitable for laboratory experiments at an undergraduate level.

Wisdom tooth removal is one of the most common oral surgical procedures performed across the world. The aim of this study was to gauge the teaching and training of impacted wisdom teeth in undergraduate dental programmes across the UK. The objectives were to identify consistencies and variations in theoretical instructions and clinical training as well as approaches to management of impacted wisdom teeth. This was a cross-sectional survey utilising an online questionnaire. A purposefully designed pro forma with open- as well as closed-ended questions was used. The questionnaire was hosted online on the school's blackboard academic suite (Emily). Prior to conducting the study, approval was gained from the Research and Ethics Committee, and all the ethical principles pertaining to data protection were strictly followed. E-mail invitations were sent to oral surgery leads in all dental schools in the UK. The participants were provided with an information sheet, and an informed consent was obtained. The participants were invited by e-mail to complete the questionnaire online voluntarily. A total of 16 dental schools offering an undergraduate course in dentistry in the UK, 13 responded positively. (response rate = 81.25%). In majority of dental schools, this subject is taught in the 4th and 5th years. A pre-clinical competency on phantom heads is a requirement in six schools, whilst only one school requires the students to pass a clinical competency. The clinical exposure of students to wisdom tooth surgery is quite variable. Although the dental schools are fairly consistent in their teaching with regard to the indications for surgical intervention, diagnostic/treatment modalities as well as the post-operative care, interesting variations were also observed. This study, perhaps the first of its kind, provides useful insights into management of impacted wisdom teeth, as taught in the undergraduate dental programmes across the UK. © 2013 John Wiley & Sons A/S.

The objective is to identify and assess the effectiveness of tools and methods of teaching communication skills to health professional students in undergraduate and postgraduate programs, to facilitate communication in hospitals, nursing homes and mental health institutions.For this review, effective communication will be defined as that which enhances patient satisfaction, safety, symptom resolution, psychological status, or reduces the impact/burden of disease and/or improved communication skills within undergraduate or postgraduate studentsThe review question is: What is the best available evidence on strategies to effectively teach communication skills to undergraduate and postgraduate medical, nursing and allied health students (nutrition and dietetics, occupational therapy, physiotherapy, speech pathology etc)? Communication is a two-way interaction where information, meanings and feelings are shared both verbally and non-verbally. Effective communication is when the message being conveyed is understood as intended. Effective communication between the health professional and patient is increasingly being recognised as a core clinical skill. Research has identified the far reaching benefits of effective communication skills including enhanced patient satisfaction, patient safety, symptom resolution and improvements in functional and psychological status. Poor communication can result in omitted or misinterpretation of information resulting in declining health of the patient. Despite the importance of effective communication in ensuring positive outcomes for both the patient and health professional, there is concern that contemporary teaching and learning approaches do not always facilitate the development of a requisite level of communication skills, both verbal and written and a difficulty for the current generation of communication skills teachers is that many have not had the experience of being taught communication skills themselves.Studies have shown that

Abstract Medical leadership and management (MLM) skills are essential in preventing failings of healthcare; it is unknown how these attitudes can be developed during undergraduate medical education. This paper aims to quantify interest in MLM and recommends preferred methods of teaching and assessment at UK medical schools. Two questionnaires were developed, one sent to all UK medical school faculties, to assess executed and planned curriculum changes, and the other sent to medical students nationally to assess their preferences for teaching and assessment. Forty-eight percent of UK medical schools and 260 individual student responses were recorded. Student responses represented 60% of UK medical schools. 65% of schools valued or highly valued the importance of teaching MLM topics, compared with 93.2% of students. Students' favoured teaching methods were seminars or lectures (89.4%) and audit and quality improvement (QI) projects (77.8%). Medical schools preferred portfolio entries (55%) and presentations (35%) as assessment methods, whilst simulation exercises (76%) and audit reports (61%) were preferred by students. Preferred methods encompass experiential learning or simulation and a greater emphasis should be placed on encouraging student audit and QI projects. The curriculum changes necessary could be achieved via further integration into future editions of Tomorrow's Doctors.

Cross-disciplinary (CD) learning experiences benefit student understanding of concepts and curriculum by offering opportunities to explore topics from the perspectives of alternate fields of study. This report involves a qualitative evaluation of CD health sciences undergraduate laboratory experiences in which concepts and students from two distinct disciplines [chemistry (CHEM) and exercise physiology (EPHE)] combined to study exercise thermoregulation and sweat analysis. Twenty-eight senior BSc Kinesiology (EPHE) students and 42 senior BSc CHEM students participated as part of their mutually exclusive, respective courses. The effectiveness of this laboratory environment was evaluated qualitatively using written comments collected from all students as well as from formal focus groups conducted after the CD laboratory with a representative cohort from each class (n = 16 CHEM students and 9 EPHE students). An open coding strategy was used to analyze the data from written feedback and focus group transcripts. Coding topics were generated and used to develop five themes found to be consistent for both groups of students. These themes reflected the common student perceptions that the CD experience was valuable and that students enjoyed being able to apply academic concepts to practical situations as well as the opportunity to interact with students from another discipline of study. However, students also reported some challenges throughout this experience that stemmed from the combination of laboratory groups from different disciplines with limited modification to the design of the original, pre-CD, learning environments. The results indicate that this laboratory created an effective learning opportunity that fostered student interest and enthusiasm for learning. The findings also provide information that could inform subsequent design and implementation of similar CD experiences to enhance engagement of all students and improve instructor efficacy.

The creation of the European Higher Education Area provides a series of opportunities for far-reaching reform of medical education and changes in the way both students and teachers work. The Bologna process must be implemented before 2010 in signatory countries, which include Spain, and must allow education and academic titles to be homologated. Medical degrees must consist of 360 European Credit Transfer System (ECTS) credits, divided into six academic years (60 credits per academic year). The Faculty of Medicine of the Autonomous University of Barcelona has already put the finishing touches to a proposal for the distribution of subjects in the new curriculum. This proposal strengthens and reassesses the teaching of microbiology and parasitology compared with current curricula, giving these subjects appropriate weight in undergraduate medical education. The teaching of medical microbiology and parasitology is included as a core subject worth 8 ECTS in the third year and two free-choice modules of 2.5 and 3 ECTS to be taken in the first semesters of the fifth and sixth years as part of the minor in "Clinical and Experimental Laboratory"(30 ECTS). The teaching of microbiology will also play an important role in the Integrated Learning in Medicine (INTEL-M) course in the third, fourth and fifth years. INTEL-M is an innovation in the syllabus based on the joint planning, organization and evaluation of a series of subjects (24.5 ECTS) that are developed in small groups of students and in the form of problem-based learning.

in 2008, a UK national survey of undergraduate teaching about ageing and geriatric medicine identified deficiencies, including failure to adequately teach about elder abuse, pressure ulcers and bio- and social gerontology. We repeated the survey in 2013 to consider whether the situation had improved. the deans of all 31 UK medical schools were invited to nominate a respondent with an overview of their undergraduate curriculum. Nominees were invited by email and letter to complete an online questionnaire quantifying topics taught, type of teaching and assessment undertaken, and the amount of time spent on teaching. one school only taught pre-clinical medicine and declined to participate. Of the 30 remaining schools, 20 responded and 19 provided analysable data. The majority of the schools (95-100%) provided teaching in delirium, dementia, stroke, falls, osteoporosis, extra-pyramidal disorders, polypharmacy, incontinence, ethics and mental capacity. Only 68% of the schools taught about elder abuse. Thirty-seven per cent taught a recognised classification of the domains of health used in Comprehensive Geriatric Assessment (CGA). The median (range) total time spent on teaching in ageing and geriatric medicine was 55.5 (26-192) h. There was less reliance on informal teaching and improved assessment:teaching ratios compared with the 2008 survey. there was an improvement in teaching and assessment of learning outcomes in ageing and geriatric medicine for UK undergraduates between 2008 and 2013. However, further work is needed to increase the amount of teaching time devoted to ageing and to improve teaching around elder abuse and the domains of health used in CGA.

"Miracle Fruit" is a taste-altering berry that causes sour foods to be perceived as sweet. The present paper describes a laboratory exercise that uses Miracle Fruit to educate students about the sensation and perception of taste. This laboratory exercise reinforces course material pertaining to the function of sweet taste receptors covered in a Sensation and Perception course at Christopher Newport University. Here we provide a step-by-step explanation of the methodology, and an example of data collected and analyzed by one group of students who participated in this laboratory exercise. The origins of the Miracle Fruit, the structure and the physiological function of miraculin (the glycoprotein responsible for the taste-modifying effect found in the pulp of the Miracle Fruit) were discussed before the laboratory exercise. Students then sampled foods known to target different types of tastes (i.e., sweet, sour, bitter and salty) and rated their perception of taste intensity for each food item. Next, students each consumed Miracle Fruit berries, then resampled each original food item and again recorded their perception of taste intensity ratings for these foods. The data confirmed that the sour food items were perceived sweeter after the Miracle Fruit was consumed. The students also completed a written assignment to assess what they learned about the origins, structure, and physiological function of Miracle Fruit. This hands-on laboratory exercise received positive feedback from students. The exercise can be used by other neuroscience educators to teach concepts related to the sensory system of taste.

The study unit on 'The spiritual dimension in care'had a Judeo-Christian orientation. It was introduced to the Diploma nursing curriculum at the University of Malta in the academic year 2002-2003. The aim was to increase students' awareness about the essence of spirituality in care so as to enable them to implement holistic care. Spirituality may or may not incorporate religiosity. Thus, believers may have spiritual needs which may include religious needs whilst the atheists and agnostics may still have spiritual needs. While considering secularisation, the Christian culture of Malta was addressed in this study unit. This article describes the content structure of the study unit based on the ASSET model (Narayanasamy, A., 1999. ASSET: a model for actioning spirituality and spiritual care education and training in nursing. Nurse Education Today 19, 274-285) and outlines the various teaching methods used. Following feedback from the first and second cohort groups in 2003 and 2004, respectively, the reviewed study unit was delivered to the third cohort group of students (n=65) in Semester 2 in the academic year 2004-2005. Apart from the use of traditional teaching methods, such as lessons and a seminar, other methods were used constantly throughout the study unit, for example, self-reflection exercises, case-studies and small group discussions to enhance learning. Recommendations are proposed to review the content of this study unit and to introduce other teaching methods for effective learning.

We describe an integrated set of experiments for the undergraduate organic laboratory that allows students to compare and contrast biological and chemical means of introducing chirality into a molecule. The racemic reduction of ethyl acetoacetate with sodium borohydride and the same reduction in the presence of a tartaric acid ligand are described, and a capillary gas chromatography column packed with a chiral material for product analysis is introduced. The results of these two hydride reactions are compared with the results of a common undergraduate experiment, the baker's yeast reduction of ethyl acetoacetate.

Spatial visualization is an essential skill in the STEM disciplines, including the geological sciences. Undergraduate students, including geoscience majors in upper-level courses, bring a wide range of spatial skill levels to the classroom. Students with weak spatial skills may struggle to understand fundamental concepts and to solve geological problems with a spatial component. However, spatial thinking skills are malleable. Using strategies that have emerged from cognitive science research, we developed a set of curricular materials that improve undergraduate geology majors' abilities to reason about 3D concepts and to solve spatially complex geological problems. Cognitive science research on spatial thinking demonstrates that predictive sketching, making visual comparisons, gesturing, and the use of analogy can be used to develop students' spatial thinking skills. We conducted a three-year study of the efficacy of these strategies in strengthening the spatial skills of students in core geology courses at three universities. Our methodology is a quasi-experimental quantitative design, utilizing pre- and post-tests of spatial thinking skills, assessments of spatial problem-solving skills, and a control group comprised of students not exposed to our new curricular materials. Students taught using the new curricular materials show improvement in spatial thinking skills. Further analysis of our data, to be completed prior to AGU, will answer additional questions about the relationship between spatial skills and academic performance, spatial skills and gender, spatial skills and confidence, and the impact of our curricular materials on students who are struggling academically. Teaching spatial thinking in the context of discipline-based exercises has the potential to transform undergraduate education in the geological sciences by removing one significant barrier to success.

The Desert Research Institute operates a high elevation facility, Storm Peak Laboratory (SPL), located on the Steamboat Springs Ski Resort at an elevation 10,500 ft. SPL provides an ideal location for long-term atmospheric research. The SPL mission statement is to ensure that the laboratory will continue to integrate climate research and education by advancing discovery and understanding within the field of pollution, aerosol and cloud interactions. During the last year, SPL has created two successful outreach programs reaching very different audiences. First, to engage students from local elementary schools, SPL established a 5th grade climate education program. This program is based on a partnership between SPL and Yampatika's&penvironmental educators. Yampatika is a non-profit outdoor environmental education organization. The program spans three days for each school and includes five elementary schools. During the first day, educators from Yampatika visit each classroom to introduce the concepts of climate and weather as well as teach students how to use scientific equipment. During the field program on the second day, students measure and record information about temperature, pressure, relative humidity, wind speed, and particle concentration while they travel to SPL via the gondola (in winter) or Suburban (in fall). Once at the laboratory, students tour the facility, discuss SPL research activities, and explore application of these activities to their curriculum. Following the field trip, Yampatika educators and SPL scientists will visit the school for a follow-up to help children explore concepts, answer questions, and evaluate students" learning. The second program, Geoscience Research at Storm Peak (GRASP), was designed to engage students from underrepresented groups and created a partnership between three Minority Serving Institutions and the University of Nevada, Reno (UNR).

The Nuclear Engineering Teaching Laboratory (NETL) at the University of Texas at Austin performs a wide variety of educational activities for students at various levels. Regular on-site courses in the areas of health physics, radiochemistry, and reactor operations are offered for university credit. Along with on-site courses, access to the reactor facility via a remote console connection allows students in an off-site classroom to conduct experiments via a "virtual" control console. In addition to the regularly scheduled courses, other programs, such as the Nuclear Regulatory Commission Summer Nuclear Engineering Institute and Office of Naval Research partnerships with Historically Black Colleges and Universities, provide access to the facility for students from other universities both domestic and foreign. And NETL hosts professional development programs such as training programs for Nuclear Regulatory Commission personnel and International Atomic Energy Agency fellowships.

A modern undergraduate organic chemistry laboratory experiment involving the Suzuki-Miyaura coupling is reported. Although Suzuki-Miyaura couplings typically employ palladium catalysts in environmentally harmful solvents, this experiment features the use of inexpensive nickel catalysis, in addition to a "green" alcohol solvent. The experiment employs heterocyclic substrates, which are important pharmaceutical building blocks. Thus, this laboratory procedure exposes students to a variety of contemporary topics in organic chemistry, including transition metal-catalyzed cross-couplings, green chemistry, and the importance of heterocycles in drug discovery, none of which are well represented in typical undergraduate organic chemistry curricula. The experimental protocol uses commercially available reagents and is useful in both organic and inorganic instructional laboratories.

Historically, nursing students have questioned the value of a nursing research course and have not appreciated the research-practice link. These are important concerns in light of the increasing emphasis on evidence-based nursing practice. The purpose of this study was to develop innovative strategies for teaching undergraduate nursing research that engage millennial learners and emphasize the relationship between evidence-based practice and clinical outcomes. Innovative assignments were developed that included interactive learning, group work, and practical applications preferred by these learners. Using a Likert scale, students' perceived effectiveness of innovative assignments and more traditional assignments were compared. Results indicated a preference for active learning assignments, reading quizzes, clinical nurse researcher presentations, and collaboration with clinical course assignments. By combining traditional assignments with innovative strategies and nursing practice applications, millennial learners were engaged and able to clearly articulate the value of the research-practice link vital to evidence-based nursing practice.

Students in introductory biology courses frequently have misconceptions regarding natural selection. In this paper, we describe six activities that biology instructors can use to teach undergraduate students in introductory biology courses how natural selection causes evolution. These activities begin with a lesson introducing students to natural selection and also include discussions on sexual selection, molecular evolution, evolution of complex traits, and the evolution of behavior. The set of six topics gives students the opportunity to see how natural selection operates in a variety of contexts. Pre- and postinstruction testing showed students' understanding of natural selection increased substantially after completing this series of learning activities. Testing throughout this unit showed steadily increasing student understanding, and surveys indicated students enjoyed the activities.

Full Text Available How can we introduce more people to the concepts of commons and institutions earlier in their careers? Despite the wide variety of academic fields that contribute to commons research, there are few undergraduate university courses that center on this theme. This study describes how a study abroad program in Thailand uses guiding questions about institutional arrangements to teach North American undergraduate students about commons resource-dependent communities' control and access regarding coasts, forests, and rivers. Components that will enable students to transfer this learning to other, more familiar settings are built into the field-based courses. This paper outlines how students learn institution-focused questioning on history of local resource management groups, resource access and use, exclusionary mechanisms, strategic collaborations, and power relations in very unfamiliar contexts. Through the lens of political ecology, the paper describes how focusing on institutions has shaped students’ understanding of the commons, and how they have been able to transfer their newly acquired institutional perspective to a range of situations in their home contexts.

Undergraduate public health and global health studies are usually found at universities with graduate programs in the disciplines. Following the experience of teaching a short course in global health within the liberal arts, we reviewed global and public health offerings at 50 liberal arts colleges for the 2009-2010 academic year. Forty-two percent had a track, concentration, or program, and 30% had global or public health student organizations. All colleges listed at least one course in the fields, with the highest number in the social sciences. However, many colleges had not coordinated them into a theme. Values of a liberal arts education are found in the study of global and public health: social responsibility, critical thinking, ethical reasoning, and knowledge of the wider world. We propose identifying these programs within the undergraduate liberal arts as global public health. Capturing interest in global public health will enhance the curriculum and student experience.In this day and age, when the world is so fluid with regard to news and information, the knowledge that unnecessary deaths are occurring and that health care lags so far behind in some regions cannot be ignored. From the standpoint of basic human rights, suffering and inequity cannot be tolerated. Williams College student during a global health short course.
Although anthropogenic climate change is generally accepted in the scientific community, there is considerable skepticism among the general population and, therefore, in undergraduate students of all majors. Students are often asked by their peers, family members, and others, whether they ``believe'' climate change is occurring and what should be done about it (if anything). I will present my experiences and recommendations for teaching the physics of climate change to both physics and non-science majors. For non-science majors, the basic approach is to try to develop an appreciation for the scientific method (particularly peer-reviewed research) in a course on energy and the environment. For physics majors, the pertinent material is normally covered in their undergraduate courses in modern physics and thermodynamics. Nevertheless, it helps to review the basics, e.g. introductory quantum mechanics (discrete energy levels of atomic systems), molecular spectroscopy, and blackbody radiation. I have done this in a separate elective topics course, titled ``Physics of Climate Change,'' to help the students see how their knowledge gives them insight into a topic that is very volatile (socially and politically).

Recent experimental evidence indicates that the ability of adults to tolerate milk, cheese, and other lactose-containing dairy products is an autosomal dominant trait that co-evolved with dairy farming in Central Europe about 7,500 years ago. Among persons of European descent, this trait is strongly associated with a C to T substitution at a polymorphic site 13,910 bp upstream of the lactase gene. This mutation results in the persistent expression of lactase into adulthood enabling individuals carrying a T(-13,910) allele to digest lactose as adults. In this report, we describe a laboratory exercise for an undergraduate molecular biology course in which students determine their own genotype at the -13,910 polymorphic site and correlate this with their ability to tolerate dairy products. The exercise is used as a tool to teach basic molecular biology procedures such as agarose gel electrophoresis, PCR1, and DNA sequencing. Students are actively engaged in the learning process, not only by analyzing their own DNA but also by applying their knowledge and skills to answer an authentic question. The exercise is also integrated with lecture material on the control of gene expression at the transcriptional level, in particular, how transcription factors can influence the activity of a promoter by binding to cis-acting DNA regulatory elements located within the proximal promoter of a gene or distant enhancer regions.

Since 2010, second-year undergraduate students of an eight-year training program leading to a Doctor of Medicine degree or Doctor of Philosophy degree in Peking University Health Science Center (PKUHSC) have been required to enter the "Innovative talent training project." During that time, the students joined a research lab and participated in some original research work. There is a critical educational need to prepare these students for the increasing accessibility of research experience. The redesigned experimental curriculum of biochemistry and molecular biology was developed to fulfill such a requirement, which keeps two original biochemistry experiments (Gel filtration and Enzyme kinetics) and adds a new two-experiment component called "Analysis of anti-tumor drug induced apoptosis." The additional component, also known as the "project-oriented experiment" or the "comprehensive experiment," consists of Western blotting and a DNA laddering assay to assess the effects of etoposide (VP16) on the apoptosis signaling pathways. This reformed laboratory teaching system aims to enhance the participating students overall understanding of important biological research techniques and the instrumentation involved, and to foster a better understanding of the research process all within a classroom setting. Student feedback indicated that the updated curriculum helped them improve their operational and self-learning capability, and helped to increase their understanding of theoretical knowledge and actual research processes, which laid the groundwork for their future research work. © 2015 The International Union of Biochemistry and Molecular Biology.
Full Text Available Background: Medical colleges in India usually follow a traditional curriculum, characterized by "discipline wise model" which compelled Medical Council of India to recommend a teaching approach characterized by maximal efforts to encourage integrated teaching (IT between traditional subject areas. Objectives: To assess the feasibility of IT; to compare IT with traditional teaching (TT and to analyze the student′s feedback and faculty feedback about perception of IT. Materials and Methods: An interventional study was conducted among fifth semester students using pre- and post-test questionnaire and student and faculty feedback forms. Students were divided randomly into two groups. IT was introduced to Group I on the topic of tuberculosis (TB by faculties of different disciplines; using methods of didactic lectures, seminars, role play, clinical case presentation, demonstration of Ziehl-Neelsen stain, Bacillus Calmette-Guerin vaccination and visit to Directly Observed Treatment Centre. Group II were exposed to TT on TB by faculties of Community Medicine using method of didactic lectures. Paired and un-paired t-test and effect size were used as statistical tests. Results : Statistically significant results were obtained using pre- and post-test questionnaire of IT. Similarly, statistically significant results were obtained using posttest results of IT and TT. Effect size that is: Cohen′s d and Pearson correlation revealed large effect which indicates high influence on student achievement. The students and faculty showed a positive attitude about IT. Conclusion: The introduction of IT was found to be feasible and to be more effective and acceptable than TT.
Full Text Available Objectives: Evaluate the way the topics for the study of pain mechanisms in general, and Orofacial Pain (OFP and temporomandibular disorders (TMDs more specifically, are addressed in undergraduate courses curricula, and also to verify the existence of specialist OFP/TMD teachers in Brazilian dental schools. Methods: Between July 2010 and January 2011, course Coordinators/Directors of all dental schools duly registered at the Ministry of Education were invited to answer a questionnaire on topics related to OFP/TMD teaching in their institutions. Results: Fifty-three dental schools representatives answered the questionnaire. The study of pain mechanisms was found to cover an average of less than 10% of the courses' total time. Pharmacology, Endodontics and Physiology were identified as the departments usually responsible for addressing pain mechanisms in dental courses. Psychosocial aspects were found to occupy a very small proportion in the syllabi, while most of the content referred to biological or somatic aspects. OFP/TMD is addressed by a specific department in only 28.4% of the participating dental schools, while in most cases (46.3%, OFP/TMD is under the responsibility of the Prosthodontics department. Only 38.5% of respondents indicated that they had a specialist OFP/TMD teacher in their Schools. Conclusion: Among the Brazilian dental schools participating in the study, the teaching of OFP/TMD was found to be insufficient, segmented or with an extremely restricted focus. This initial assessment indicates that Curricular Guidelines for the study of OFP/TMD at undergraduate dental schools should be developed and implemented to facilitate their appropriate inclusion into the curricula and in specific pedagogical projects.

Beginning medical teachers often see themselves as doctors or researchers rather than as teachers. Using both figured worlds theory and dialogical self theory, this study explores how beginning teachers in the field of undergraduate medical education integrate the teacher role into their identity. A qualitative study was performed, involving 18 beginning medical teachers at a Dutch medical school. The teachers were interviewed twice and kept a logbook over a period of 7 months. The study shows that the integration of the teacher role into the teachers' identity was hampered by the idea that teaching is perceived by others as a low status occupation. Some teachers experienced significant tension because of this, while others showed resilience in resisting the negative associations that were thought to exist regarding teaching. The teachers used five different identity narratives in order to integrate the teacher role into their identity, in which the positions of teacher and doctor or researcher were found to be combined, adopted or rejected in diverse ways. The five identity narratives were: (1) coalition between the I-position of teacher and other I-positions; (2) no integration of the I-position of teacher: holding on to other I-positions; (3) construction of the I-position of teacher and other I-positions as opposites; (4) coalition between the I-position of teacher and a third position of coordinator; and (5) meta-position: trivialising the importance of status. These identity narratives offer starting points for supporting undergraduate teachers during their early professional years.

There is growing interest in methods of teaching critical appraisal skills at undergraduate and postgraduate levels. We describe an approach using a journal club and subsequent letter writing to teach critical appraisal and writing skills to medical undergraduates. The exercise occurs during a 3-week public health medicine attachment in the third year of the undergraduate curriculum. Students work in small groups to appraise a recently published research paper, present their findings to their peers in a journal club, and draft a letter to the journal editor. Evaluation took place through: informal and formal feedback from students; number of letters written, submitted and published, and a comparison of marks obtained by students submitting a literature review assignment with and without critical appraisal teaching during the public health attachment. Feedback from students was overwhelmingly positive. In the first 3(1/2) years, 26 letters have been published or accepted for publication, and 58 letters published on the Internet. There were no significant differences in overall marks or marks for the critical appraisal component of the literature review assignments between the two student groups. We believe our approach is an innovative and enjoyable method for teaching critical appraisal and writing skills to medical students. Lack of difference in marks in the literature review between the student groups may reflect its insensitivity as an outcome measure, contamination by other critical appraisal teaching, or true ineffectiveness.

Undergraduate otolaryngology teaching in the UK is generally limited primarily due to curriculum time constraints with traditional face-to-face (FtF) teaching being restrained by the limitations of time and location. Advances in network technology have opened up new doors for the delivery of teaching in the form of online learning. This study compares a traditional instructor-led lecture with synchronous e-learning (SeL) using otolaryngological emergencies teaching as an educational intervention. A randomised controlled trial was designed involving two groups of medical students attending an otolaryngology emergencies management lecture: one present FtF and the other viewing the streamed lecture online. The primary outcome measure was improvement between pre-and post-lecture test scores. Secondary outcomes comprised the students' ratings of the lecture on a Likert-type scale. Students in both groups had improved test scores following the lecture (p teaching in improving students' knowledge on the management of otolaryngological emergencies, and that it is generally positively perceived by medical undergraduates. This highlights the potential utility of e-learning technology in undergraduate otolaryngology training.

Motivated by the contracting nature of the Portuguese age pyramid, and thereby the ever increasing geriatric population, the aim of this study was to compare the number of European Credit Transfer and Accumulation System Credits dedicated to Geriatrics with Pediatrics in Portuguese Medical Schools. An observational, descriptive and cross-sectional study was conducted and included six Portuguese Medical Schools that have six years of training and a total of 360 credits. The study plans were obtained from the medical schools' websites or requested. Schools were grouped in modular/classic teaching methodology and the courses were categorized in mandatory/optional and specific/related. The credits of Geriatrics and Pediatrics were compared. Four schools had classical methodology and two had a modular one. Overall, they had more credits dedicated to Pediatrics than Geriatrics. Three schools offered mandatory courses specifically oriented to Geriatrics (1.5 - 8 credits) compared to all schools mandatory courses courses on Pediatrics (5.7 - 26.5 credits). The ratio of averages of mandatory specific courses (Pediatrics/Geriatrics) was 12.4 in the classical and 1.5 in the modular group. Pediatrics teaching has revealed to be superior to Geriatrics in all categories. Based on our results, we consider the Portuguese Geriatrics' undergraduate teaching sub-optimal. Nowadays, geriatric population is quantitatively similar to pediatric population. Efforts should be made to adequate Geriatrics teaching to our reality in order to provide a more adequate health care to this age group.

Full Text Available Background. The concept of peer-assisted teaching or peer-assisted learning (PAL has been receiving more attention in the teaching of medical and allied health students. Many advantages have been described in the literature, but much more research is needed. Challenges with the academic platform at a specific institution of higher learning necessitate investigation into the current literature on PAL, which can inform decisions in terms of teaching and learning of allied health professions students. Objective. To critically appraise evidence of the effectiveness and implementation of PAL during the professional clinical skills training of undergraduate students in allied health professions to make informed future decisions on teaching and learning. Methods. A literature search was conducted by an experienced librarian in the Faculty of Health Sciences, University of the Free State, Bloemfontein, South Africa and the researcher in multiple electronic databases (MEDLINE, CINAHL, Africa-Wide Information, ERIC and PubMed published from 2000 to 2014. Results. One hundred and seventy-five articles on PAL in health professions training were identified. The selected articles (n=20 were independently critically appraised by two researchers by means of the standardised critical appraisal skills programme (CASP and the Author Manuscript of the National Institutes of Health on Appraising Quantitative Research in Health Education. Nine articles were identified to be reviewed (two by the same author. Conclusion. The findings with regard to the limited number of articles reviewed suggested that PAL may address some of the needs of the new generation of students and may be beneficial to the student tutor, student tutee and clinical supervisor. More evidence is needed in terms of the questions arising from the review, especially with regard to occupational therapy, dietetics and nutrition, and optometry, to fully implement PAL.
Continuous advances in medical laboratory technology have driven major changes in the practice of laboratory medicine over the past two decades. The importance of the overall quality of a medical laboratory has been ever-increasing in order to improve and ensure the quality and safety of clinical practice by physicians in any type of medical facility. Laboratory physicians and professional staff should challenge themselves more than ever in various ways to cooperate and contribute with practicing physicians for the appropriate utilization of laboratory testing. This will certainly lead to a decrease in inappropriate or unnecessary laboratory testing, resulting in reducing medical costs. In addition, not only postgraduate, but also undergraduate medical education/training systems must be markedly innovated, considering recent rapid progress in electronic information and communication technologies.

Compton scattering phenomenon is experimentally studied during the medical physics laboratory course at the University of Campinas (UNICAMP). The Teaching Laboratory of Medical Physics from IFGW/UNICAMP has a structure for its development: a fixed 137 Cs sealed source with activity 610.5MBq, whose emitted radiation collides on a target, and a scintillation detector that turns around the target and detects scattered photons spectrum. 137 Cs source is stored in a lead shield with a collimating window for the gamma radiation emitted with energy of 0.662MeV. This source is exposed only when attenuation barrier protecting the collimating window is opened. The process of opening and closing the attenuation barrier may deliver radiation dose to users when done manually. Taking into account the stochastic harmful effects of ionizing radiation, the objective of this project was to develop an automatic exposure system of the radioactive source in order to reduce the dose during the Compton scattering experiment. The developed system is micro controlled and performs standard operating routines and responds to emergencies. Electromagnetic lock enables quick closing barrier by gravity in case of interruption of electrical current circuit. Besides reducing the total dose of lab users, the system adds more security in the routine since it limits access to the source and prevents accidental exposure. (author)

Adsorption laboratory experiment for undergraduate chemical engineering program is discussed. The experiment demonstrated adsorption of copper ions commonly found in wastewater using bio-sorbent, i.e. agricultural wastes. The adsorption was performed in a batch mode under various parameters: adsorption time (up to 120 min), initial pH (2 to 6), adsorbent dose (2.0 to 12.0 g L-1), adsorbent size (50 to 170 mesh), initial Cu2+ concentration (25 to 100 ppm) and temperatures (room temp to 40°C). The equilibrium and kinetic data of the experiments were calculated using the two commonly used isotherms: Langmuir and Lagergren pseudo-first-order kinetics. The maximum adsorption capacity for Cu2+ was found as 94.34 mg g-1. Thermodynamically, the adsorption process was spontaneous and endothermic. The calculated activation energy for the adsorption was observed as high as 127.94 kJ mol-1. Pedagogically, the experiment was assumed to be important in increasing student understanding of kinetic, equilibrium and thermodynamic concepts.

This study aimed to assess the effectiveness of a blended-teaching intervention using Internet-based tutorials coupled with traditional lectures in an introduction to research undergraduate nursing course. Effects of the intervention were compared with conventional, face-to-face classroom teaching on three outcomes: knowledge, satisfaction, and self-learning readiness. A two-group, randomized, controlled design was used, involving 112 participants. Descriptive statistics and analysis of covariance (ANCOVA) were performed. The teaching method was found to have no direct impact on knowledge acquisition, satisfaction, and self-learning readiness. However, motivation and teaching method had an interaction effect on knowledge acquisition by students. Among less motivated students, those in the intervention group performed better than those who received traditional training. These findings suggest that this blended-teaching method could better suit some students, depending on their degree of motivation and level of self-directed learning readiness.
This paper summarizes my experiences teaching a 28-hour course on the bacterial world for undergraduate students in the humanities and the social sciences at the Hebrew University of Jerusalem. This course was offered in the framework of a program in which students must obtain credit points for courses offered by other faculties to broaden their education. Most students had little biology in high school and had never been exposed to the basics of chemistry. Using a historical approach, highlighting the work of pioneers such as van Leeuwenhoek, Koch, Fleming, Pasteur, Winogradsky and Woese, I covered a broad area of general, medical, environmental and evolutionary microbiology. The lectures included basic concepts of organic and inorganic chemistry necessary to understand the principles of fermentations and chemoautotrophy, and basic molecular biology to explain biotechnology using transgenic microorganisms and molecular phylogeny. Teaching the basics of microbiology to intelligent students lacking any background in the natural sciences was a rewarding experience. Some students complained that, in spite of my efforts, basic concepts of chemistry remained beyond their understanding. But overall the students' evaluation showed that the course had achieved its goal. © FEMS 2015. All rights reserved. For permissions, please e-mail: email@example.com.

To find out the impact of teaching clinical pharmacology and rational therapeutics (CPT) to medical undergraduates (UGs) and interns. This cross-sectional, prospective study was conducted on three UGs batches and interns using two pretested validated structured questionnaires, modified from the work of Tobaiqy et al. The study was approved by the Institutional Ethics Committee. ANOVA and Chi-square test were used for statistical analysis. The value of P < 0.05 was considered statistically significant. A total of 379 UGs and 96 interns participated in this study. Mean knowledge score of interns was significantly reduced as compared to UGs (P < 0.0001). A significant increase in confidence for unsupervised prescribing of nonsteroidal anti-inflammatory drugs (99%), oral rehydration salt, iron salts was perceived among interns as compared to UGs (P < 0.05). However, 63.5% confessed problems in selection of drugs, drug-drug interactions, prescribing in special patient population. Although they were confident prescribing fixed dose combination for adult patients (89.5%), majority were hesitant to prescribe opioids (77%), steroids (76%), vaccines (75%), and antihypertensives (62%). The theoretical CPT teaching transfers knowledge to UGs; however, it is not retained in internship and does not adequately prepare interns to prescribe safe and rational drugs.

The urogenital physical examination is an important aspect of patient encounters in various clinical settings. Introductory clinical skills sessions are intended to provide support and alleviate students' anxiety when learning this sensitive exam. The techniques each Canadian medical school uses to guide their students through the initial urogenital examination has not been previously reported. This study surveyed pre-clerkship clinical skills program directors at the main campus of English-speaking Canadian medical schools regarding the curriculum they use to teach the urogenital examination. A response rate of 100% was achieved, providing information on resources and faculty available to students, as well as the manner in which students were evaluated. Surprisingly, over one-third of the Canadian medical schools surveyed failed to provide a setting in which students perform a urogenital examination on a patient in their pre-clinical years. Additionally, there was no formal evaluation of this skill set reported by almost 50% of Canadian medical schools prior to clinical training years. To ensure medical students are confident and accurate in performing a urogenital examination, it is vital they be provided the proper resources, teaching, and training. As we progress towards a competency-based curriculum, it is essential that increased focus be placed on patient encounters in undergraduate training. Further research to quantify students' exposure to the urogenital examination during clinical years would be of interest. Without this commitment by Canadian medical schools, we are doing a disservice not only to the medical students, but also to our patient population.

The classical didactic lecture has been the cornerstone of the theoretical undergraduate medical education. Their efficacy however reduces due to reduced interaction and short attention span of the students. It is hypothesized that the interactive response pad obviates some of these drawbacks. The aim of this study was to evaluate the effectiveness of an interactive response system by comparing it with conventional classroom teaching. A prospective comparative longitudinal study was conducted on 192 students who were exposed to either conventional or interactive teaching over 20 classes. Pre-test, Post-test and retentions test (post 8-12 weeks) scores were collated and statistically analysed. An independent observer measured number of student interactions in each class. Pre-test scores from both groups were similar (p = 0.71). There was significant improvement in both post test scores when compared to pre-test scores in either method (p Students taught with the interactive method were likely to score 8-10% higher (statistically significant) in the immediate post class time and 15-18% higher (statistically significant) after 8-12 weeks. The number of student-teacher interactions increases when using the interactive response pads.

Parasitic diseases are a major public health problem in the tropical and sub tropical countries including the subcontinent region. We aimed to assess methods of Parasitology education in medical schools of Karachi Pakistan. Ten medical schools in Karachi, Pakistan were sent a structured questionnaire collecting information on different aspects of Parasitology education. The collected data was analyzed using SPSS version 14.0. The response rate of this study was 90%. Majority of the schools in Karachi, Pakistan (78%) taught Parasitology concurrently with Microbiology, Pathology, Pharmacology and Forensic medicine in third and fourth year of undergraduate training. More than 20 hours were spent on teaching through didactic lectures (56%), interactive lectures (22%), problem based learning (PBL) (22%), clinical cases (11%) and small group discussions (89%). A Clinical Microbiologist or Parasitologist taught Parasitology by using transparencies, handouts and/or computer aids. Variation in education methods existed mainly in the private medical schools. Medical curricula were meeting the European standards for teaching of Parasitology. However, there is a need for revision and modification in the curricula owing to the high burden of parasitic diseases in the subcontinent region.

Hydrological sciences teaching always needs to make a link between the classroom and the outside world. This can be done with fieldwork and excursions, but the increasing availability of open educational resources gives more-and-more other options to make theory more understandable and applicable. In the undergraduate teaching of hydrology at the University of Birmingham we make use of a number of tools to enhance the hydrology 'experience' of students. Firstly, we add hydrological science videos available in the public domain to our explanations of theory. These are both visualisations of concepts and recorded demonstrations in the field or the lab. One example is the concept of catchments and travel times which has been excellently visualised by MetEd. Secondly, we use a number of mobile phone apps, which provide virtual reality information and real-time monitoring information. We use the MySoil App (by Natural Environment Research Council (NERC), British Geological Survey (BGS) and Centre for Ecology & Hydrology (CEH)) and iGeology / iGeology3D (by BGS) to let students explore soil properties and hydrogeology of an area of interest. And we use the River Levels App (by OGL based on Environment Agency real time data) for exploring real time river levels and investigating spatial variability. Finally, we developed small hands-on projects for students to apply the theory outside the classroom. We for instance let them do simple infiltration experiments and ask them to them design a measurement plan. Evaluations have shown that students enjoy these activities and that it helps their learning. In this presentation we hope to share our experience so that the options for using open (educational) resources for hydrology teaching become more used in linking the classroom to the outside world.

A number of studies have shown that the traditional lecture suffers from limitations in the development of many important competencies such as reasoning ability for nursing professionals. In view of this issue, the authors present a promising alternative to the traditional lecture: the Guided University Debate (GUD). With regard to this aim a teaching-learning sequence of schizophrenia is described based on the GUD. Next, the improvement in the argumentative and declarative knowledge of the students who have participated in the said methodology is demonstrated. Quasi-experimental study with pre-test and post-test design to measure differences in the improvement of declarative and argumentative knowledge. To determine if there is a statistically significant difference in the score obtained in the pre-test and in the post-test score a parametric t-tests was carried. 64 students participated in the study. Implementation of the study took place during the 2015-2016 academic year in the third year of the Nursing undergraduate degree course in the University of the Basque Country (UPV/EHU) as part of the Mental Health class. The results showed a statistically-significant improvement in the students' scores for all learning outcomes analysed: Identifies symptoms of schizophrenia (p≤0.001), identifies the nursing interventions (p≤0.001), provides a rationale for nursing interventions (p≤0.001) and provides evidence of nursing interventions (p≤0.001). That is, the declarative and argumentative capacity of the group improved significantly with the Guided University Debate methodology. Although the teaching design feasibility and outcomes may vary in different contexts, based on this studies' positive outcome, the authors call today's educators to be able to use GUD as a teaching method.

The purpose of this study was to develop and implement a blended course (a combined face-to-face and online instruction) on undergraduate oral radiology and evaluate it by comparing its educational effectiveness (derived from students' performance and answers to questionnaires) to a conventional course's. Students' attitudes concerning the blended methodology were also registered. An original course was developed and implemented, and its electronic version was uploaded to an e-learning educational platform. The course was attended by two groups of final-year students, who were taught by either the conventional face-to-face methodology or the blended learning methodology. Students answered a series of questionnaires, before and after following the course, regarding their perceptions, attitudes and evaluation of the course. Additionally, they completed knowledge assessment tests and their grades (before and after the course) were compared. Educational effectiveness of the course was determined by analysing the results of the questionnaires and the tests. Students in the blended group performed significantly better than their colleagues of the conventional group in the post-course knowledge test, and female students of the blended group performed better than male students. Students evaluated high the course content, organisation, educational material, and the blended group students additionally appreciated the course design and clarity of instructions. Students' attitudes towards elements of blended learning (effectiveness, motivation and active engagement) were very positive. Most of the blended group students, who attended the face-to-face meeting (approx. 91%), evaluated it as helpful for summarising the subject and clarifying difficult issues. Blended learning is effective and well evaluated by dental students and can be implemented in undergraduate curriculum for teaching oral radiology. © 2011 John Wiley & Sons A/S.

Anaesthesia encompasses a broad range of knowledge and skills of relevance to graduating doctors. For the majority of new doctors, an undergraduate clinical rotation is their only exposure to anaesthesia practice. However, the content and approach to undergraduate anaesthesia education varies between institutions. We explored our students' views and experiences, and teaching approaches and expectations of consultant anaesthetists during a clinical attachment in anaesthesia. Our mixed-method design included student and staff surveys, logbook analysis and student focus groups. Logbook analysis of all 202 students showed mean numbers of attempts for bag-mask ventilation, laryngeal mask insertion, tracheal intubation and IV cannulation were 6.8, 3.9, 3.3 and 4.5, respectively. Focus group responses (11 students, three groups) suggested a mismatch between students' expectations of performing clinical skills and the available opportunities, particularly for IV cannulation. Students often felt reluctant to ask anaesthetists to teach them, and appreciated clinician-led engagement in all aspects of learning patient management. Among the 78 anaesthetists (29.3%) responding to the survey, the five tasks most frequently identified as suitable for teaching to students all related to airway management. Our study found much unanticipated variability in student exposure, teaching practice and attitudes to teaching various skills or procedures between anaesthetists, and student opinion of their clinical attachment. The findings resulted in a review of many aspects of the attachment. It is likely that other institutions will have similar variability and we recommend they undertake similar exercises to optimise teaching and learning opportunities for undergraduate anaesthesia.

The aim of this study is to evaluate a teaching strategy designed to teach first-year undergraduate life sciences students at a research university how to learn to read authentic research articles. Our approach—based on the work done in the field of genre analysis and argumentation theory—means that we teach students to read research articles by teaching them which rhetorical moves occur in research articles and how they can identify these. Because research articles are persuasive by their very nature, we focused on the rhetorical moves that play an important role in authors’ arguments. We designed a teaching strategy using cognitive apprenticeship as the pedagogical approach. It was implemented in a first-year compulsory course in the life sciences undergraduate program. Comparison of the results of a pretest with those of the posttest showed that students’ ability to identify these moves had improved. Moreover, students themselves had also perceived that their ability to read and understand a research article had increased. The students’ evaluations demonstrated that they appreciated the pedagogical approach used and experienced the assignments as useful. On the basis of our results, we concluded that students had taken a first step toward becoming expert readers. PMID:26086657

To prepare students to understand a changing climate, it is imperative that we equip educators with the best possible tools and methods for reaching their audience. As part of the Climate Literacy and Energy Awareness Network (CLEAN) professional development efforts, two workshops for undergraduate faculty were held in 2012. These workshops used a variety of activities to help faculty learn about recent climate research, take part in demonstrations of successful activities for teaching climate topics, and collaborate to create new teaching materials. The workshops also facilitated professional networking among participants. Both workshops were held online, eliminating the need for travel, encouraging participants without travel funds to attend, and allowing international collaborations and presentations. To create an authentic experience, the workshop used several technologies such as the Blackboard Collaborate web conferencing platform, SERC's web-based collaboration tools and online discussion threads, and conference calls. The workshop Communicating Climate Science in the Classroom, held in April 2012, explored practices for communicating climate science and policy in the classroom and provided strategies to improve student understanding of this complex and sensitive topic. Workshop presentations featured public opinion research on Americans' perceptions of climate change, tactics for identifying and resolving student misconceptions, and methods to address various "backfire effects" that can result from attempts to correct misinformation. Demonstrations of teaching approaches included a role-playing simulation of emissions negotiations, Princeton's climate stabilization wedges game, and an activity that allows students to use scientific principles to tackle misinformation. The workshop Teaching Climate Complexity was held in May 2012. Teaching the complexities of climate science requires an understanding of many facets of the Earth system and a robust pedagogic

This study explored the impact of a novel inquiry-based astronomy laboratory curriculum designed using the Backwards Faded Scaffolding inquiry teaching framework on non-science majoring undergraduate students' views of the nature of scientific inquiry (NOSI). The study focused on two aspects of NOSI: The Distinction between Data and Evidence (DvE), and The Multiple Methods of Science (MMS). Participants were 220 predominately non-science majoring undergraduate students at a small, doctoral granting, research-extensive university in the Rocky Mountain region of the United States. The student participants were enrolled in an introductory astronomy survey course with an associated laboratory section and were selected in two samples over consecutive fall and spring semesters. The participants also included four of the graduate student instructors who taught the laboratory courses using the intervention curriculum. In the first stage, student participant views of NOSI were measured using the VOSI-4 research instrument before and after the intervention curriculum was administered. The responses were quantified, and the distributions of pre and posttest scores of both samples were separately analyzed to determine if there was a significant improvement in understanding of either of the two aspects of NOSI. The results from both samples were compared to evaluate the consistency of the results. In the second stage, the quantitative results were used to strategically design a qualitative investigation, in which the four lab instructors were interviewed about their observations of how the student participants interacted with the intervention curriculum as compared to traditional lab activities, as well as their suggestions as to how the curriculum may or may not have contributed to the results of the first stage. These interviews were summarized and analyzed for common themes as to how the intervention curriculum influenced the students' understandings of the two aspect of

Academic leagues have been consolidated as instruments of medical teaching and for the introducing of medical students to practice of specialties, including anesthesiology. As the role of leagues in the development process of competencies and learning of their students is not well known, the learning of members of an anesthesiology academic league was evaluated after participating in its activities for one year. Students of an anesthesiology academic league were followed up from March to December 2010 and evaluated through objective cognitive tests of multiple choice applied before the beginning of activities and after their conclusion. Attendance in activities and epidemiologic profile of students were correlated with the tests results. Twenty medical students from 3rd to 6th year were analyzed, with an average age of 22.8 (21-26) years. The average participation in the proposed activities was 10.4/13 (80%). The average of right answers on the first test was 8.1/17 (47.6%), and 3rd year students had lower grades (pgrades of different years of the medical undergraduation. A strong relationship between participation in activities and improved grades was found (r=0.719; p<0.001). Students who participated in the league had improvement in knowledge evaluation tests, suggesting that the league is a useful teaching instrument that can provide improved learning of anesthesiology. Participation in activities was connected with improved performance. Activities developed in leagues may have a positive role in students' academic education, more specifically in this article, in anesthesiology. Copyright © 2012 Elsevier Editora Ltda.

Cephalometry is important for orthodontic diagnosis and treatment planning and is part of the core curriculum for training dentists. Training involves identifying anatomical landmarks. The aim of this investigation was to assess whether e-learning improves learning efficiency; a programme specifically designed for this purpose was compared to commercially available software. Thirty undergraduate students underwent traditional training of cephalometry consisting of lectures and tutorials. Tracing skills were tested immediately afterwards (T0). The students were then randomly allocated to three groups: 10 students served as control (CF); they were asked to improve their skills using the material provided so far. Ten students were given a program specifically designed for this study that was based on a power point presentation (PPT). The last group was given a commercially available program that included teaching elements (SW). The groups were tested at the end the six week training (T1). The test consisted of tracing 30 points on two radiographs and a point score improvement was calculated. The students were interviewed after the second test. Both e-learning groups improved more than the traditional group. Improvement scores were four for CF; 8.6 for PPT and 2.8 for SW. For PPT all participants improved and the student feedback was the best compared to the other groups. For the other groups some candidates worsened. Blended learning produced better learning outcomes compared to using a traditional teaching method alone. The easy to use Power Point based custom software produced better results than the commercially available software. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To evaluate the effectiveness of a novel multimedia learning tool (MMLT) for teaching a method of approaching common ophthalmologic presentations. Randomized clinical study. 25 second-year medical students at Queen's University. We evaluated 2 MMLTs pertaining to common ophthalmologic presentations--acute visual loss and cataract--through the use of a randomized clinical study. Subjects were randomized either to watch a short-form video or to read a textbook excerpt for both cataract and acute visual loss. If randomized to one MMLT for the first module, the subject was allocated to the other modality for the second module. The main outcomes of interest were knowledge retention as measured by a short multiple-choice questionnaire, efficiency, and user preference. A trend was noted whereby subjects randomized to an MMLT had higher composite scores on multiple-choice questionnaires (mean score MMLT = 75.2% vs text = 67.5%; t test = 1.535; df = 22; p value = 0.139). Additionally, those who watched an MMLT spent 72% less time reviewing the education content (29 min vs 8 min; t test = 3.955, p value = 0.0003). Of the sample, 87% preferred the MMLT over the text. MMLTs can significantly reduce learning time without sacrificing knowledge retention in undergraduate students of ophthalmology. Copyright © 2012 Canadian Ophthalmological Society.

One of the most important aim of the geography and social science courses is to gain the ability of reading, analysing and understanding maps. There are a lot of themes related with maps and map concepts in social studies education. Geographical location is one of the most important theme. Geographical location is specified by geographical coordinates called latitude and longitude. The geographical coordinate system is the primary spatial reference system of the earth. It is always used in cartography, in geography, in basic location calculations such as navigation and surveying. It’s important to support teacher candidates, to teach maps and related concepts. Cartographers also have important missions and responsibilities in this context. The purpose of this study is to evaluate the knowledge of undergraduate students, about the geographical location. For this purpose, a research has been carried out on questions and activities related to geographical location and related concepts. The details and results of the research conducted by the students in the study are explained.

The Advanced Visual Quantum Mechanics project was conceived to provide computer-centered, activities-based instructional materials to upper-level undergraduate physics majors. This study implements one curriculum development cycle of research, development, and classroom testing for a single unit, The Shape and Behavior of the Wave Function, of these materials. It is designed to be a proof of concept pilot study for the project. The cycle began with an extensive review of existing research drawing on results from the general fields of cognitive science and educational research as well as more specific research regarding the use of computers in instruction and the teaching and learning of quantum mechanics. It continued with the development of written materials, a computer program, and assessment instruments all extensively based on this research. It concluded with a field test garnering an outcome of positive student and instructor attitudes and perceptions of learning gains as well as actual gains similar or superior to traditional instruction---even in the face of usage that diverged widely from that intended. Based on these results, we recommend the continuation of the Advanced Visual Quantum Mechanics project. This work would include further testing and revision of these materials, similar development and classroom testing of further materials, and new research within the context of that testing. Consideration should also be given to similar projects that address other physics subject areas.

Nurses play a pivotal role in responding to the changing needs of community health care. Therefore, nursing education must be relevant, responsive, and evidence based. We report a case study of curriculum development in a community nursing unit embedded within an undergraduate nursing degree. We used action research to develop, deliver, evaluate, and redesign the curriculum. Feedback was obtained through self-reflection, expert opinion from community stakeholders, formal student evaluation, and critical review. Changes made, especially in curriculum delivery, led to improved learner focus and more clearly linked theory and practice. The redesigned unit improved performance, measured with the university's student evaluation of feedback instrument (increased from 0.3 to 0.5 points below to 0.1 to 0.5 points above faculty mean in all domains), and was well received by teaching staff. The process confirmed that improved pedagogy can increase student engagement with content and perception of a unit as relevant to future practice. Copyright 2011, SLACK Incorporated.

In a large (250 registrants) general education lecture course, neuroscience principles were taught by two professors as co-instructors, starting with simple brain anatomy, chemistry, and function, proceeding to basic brain circuits of pleasure and pain, and progressing with fellow expert professors covering relevant philosophical, artistic, marketing, and anthropological issues. With this as a base, the course wove between fields of high relevance to psychology and neuroscience, such as food addiction and preferences, drug seeking and craving, analgesic pain-inhibitory systems activated by opiates and stress, neuroeconomics, unconscious decision-making, empathy, and modern neuroscientific techniques (functional magnetic resonance imaging and event-related potentials) presented by the co-instructors and other Psychology professors. With no formal assigned textbook, all lectures were PowerPoint-based, containing links to supplemental public-domain material. PowerPoints were available on Blackboard several days before the lecture. All lectures were also video-recorded and posted that evening. The course had a Facebook page for after-class conversation and one of the co-instructors communicated directly with students on Twitter in real time during lecture to provide momentary clarification and comment. In addition to graduate student Teaching Assistants (TAs), to allow for small group discussion, ten undergraduate students who performed well in a previous class were selected to serve as discussion leaders. The Discussion Leaders met four times at strategic points over the semester with groups of 20-25 current students, and received one credit of Independent Study, thus creating a course within a course. The course grade was based on weighted scores from two multiple-choice exams and a five-page writing assignment in which each student reviewed three unique, but brief original peer-review research articles (one page each) combined with expository writing on the first

Increasing retention of students in science, technology, engineering, or mathematics (STEM) programs of study is a priority for many colleges and universities. This study examines an undergraduate teaching assistant (UTA) program implemented in a general chemistry course for STEM majors to provide peer learning assistance to entrylevel students. This study measured the content knowledge growth of UTAs compared to traditional graduate teaching assistants (GTAs) over the semester, and described the development of peer learning assistance skills of the UTAs as an outcome of semesterlong training and support from both science education and STEM faculty. Impact of the UTA program on final exam grades, persistence of students to enroll in the next chemistry course required by their intended major, and STEM identity of students were estimated. The study sample comprised 284 students in 14 general chemistry recitation sections led by six UTAs and 310 students in 15 general chemistry recitation sections led by three traditional GTAs for comparison. Results suggested that both UTAs and GTAs made significant learning gains in general chemistry content knowledge, and there was no significant difference in content knowledge between UTA and GTA groups. Student evaluations, researcher observations, and chemistry faculty comments confirm UTAs were using the learning strategies discussed in the semester-long training program. UTA-led students rated their TAs significantly higher in teaching quality and student care and encouragement, which correlated with stronger STEM recognition by those students. The results of hierarchical linear model (HLM) analysis showed little variance in final exam grades explained by section-level variables; most variance was explained by student-level variables: mathematics ACT score, college GPA, and intention to enroll in the next general chemistry course. Students having higher college GPAs were helped more by having a UTA. Results from logistic

Full Text Available BACKGROUND This study was conducted to apply case based learning in undergraduate teaching of otorhinolaryngology at an Indian medical school and obtain the students’ perception on this approach of learning. METHODS Case based learning (CBL was introduced in otorhinolaryngology teaching on the current batch during final MBBS part I over a period of 3 months for 5 topics. Students’ perception was obtained, then after using a pre-validated questionnaire incorporating responses based on 1 to 5 Likert scale, which were analysed statistically in the form of percentages and proportions. RESULTS 145 students who had attended all the sessions of CBL participated in the study. More than half of the students enjoyed the CBL method and found it as interest generating with improved attention span. About two-thirds also felt that this method improved understanding, increased retention and were in favour of incorporation of this method in day-to-day teaching. CONCLUSION A balanced and well-planned collaboration of traditional and case based learning methods may prove an effective teaching methodology in Otorhinolaryngology at undergraduate level.

Based on reform practice of university education integration, this article gives a deepening research on the essence and implement methods of undergraduate tutorial system. To implement and strengthen the function of undergraduate tutorial system, we need to increase teachers’ comprehensive quality training, build a multiple-dimension, full-process and whole-staff-participation educational concept, absorb the enterprise mentors to give guidance on students’ career planning and implement the scientific and reasonable undergraduate administrative evaluation system. With continuous theory exploration and practice research, the quality of undergraduate talent training has been gradually improved.

To review the initial experience of blending a variety of online educational techniques with traditional face to face or contact-based teaching methods to deliver final year undergraduate radiology content at a UK Medical School. The Brighton and Sussex Medical School opened in 2003 and offers a 5-year undergraduate programme, with the final 5 spent in several regional centres. Year 5 involves several core clinical specialities with onsite radiology teaching provided at regional centres in the form of small-group tutorials, imaging seminars and also a one-day course. An online educational module was introduced in 2007 to facilitate equitable delivery of the year 5 curriculum between the regional centres and to support students on placement. This module had a strong radiological emphasis, with a combination of imaging integrated into clinical cases to reflect everyday practice and also dedicated radiology cases. For the second cohort of year 5 students in 2008 two additional online media-rich initiatives were introduced, to complement the online module, comprising imaging tutorials and an online case discussion room. In the first year for the 2007/2008 cohort, 490 cases were written, edited and delivered via the Medical School managed learning environment as part of the online module. 253 cases contained a form of image media, of which 195 cases had a radiological component with a total of 325 radiology images. Important aspects of radiology practice (e.g. consent, patient safety, contrast toxicity, ionising radiation) were also covered. There were 274,000 student hits on cases the first year, with students completing a mean of 169 cases each. High levels of student satisfaction were recorded in relation to the online module and also additional online radiology teaching initiatives. Online educational techniques can be effectively blended with other forms of teaching to allow successful undergraduate delivery of radiology. Efficient IT links and good image quality

Year 5 involves several core clinical specialities with onsite radiology teaching provided at regional centres in the form of small-group tutorials, imaging seminars and also a one-day course. An online educational module was introduced in 2007 to facilitate equitable delivery of the year 5 curriculum between the regional centres and to support students on placement. This module had a strong radiological emphasis, with a combination of imaging integrated into clinical cases to reflect everyday practice and also dedicated radiology cases. For the second cohort of year 5 students in 2008 two additional online media-rich initiatives were introduced, to complement the online module, comprising imaging tutorials and an online case discussion room. Results: In the first year for the 2007/2008 cohort, 490 cases were written, edited and delivered via the Medical School managed learning environment as part of the online module. 253 cases contained a form of image media, of which 195 cases had a radiological component with a total of 325 radiology images. Important aspects of radiology practice (e.g. consent, patient safety, contrast toxicity, ionising radiation) were also covered. There were 274,000 student hits on cases the first year, with students completing a mean of 169 cases each. High levels of student satisfaction were recorded in relation to the online module and also additional online radiology teaching initiatives. Conclusion: Online educational techniques can be effectively blended with other forms of teaching to allow successful undergraduate delivery of

to assess the outcomes and competencies of medical undergraduates regarding their learning abilities after introducing Clinical Presentation Curriculum (CPC) instead of Traditional Curriculum in Quaid-i-Azam Medical College, Bahawalpur. a cross-sectional comparative study. 3rd and 4th year MBBS class during session 2004-2005 at Quaid-i-Azam Medical College (QMC), Bahawalpur. Five hundred students of 3rd year and 4th year MBBS who were taught for 176 and 172 hours respectively, appeared in 20 tests during session 2004-2005, were included in the study. Students were taught pathology according to Traditional Curricular model for 88 and 86 hours, respectively during college hours. Ten class tests each of 3rd and 4th year MBBS were taken and scores recorded. In the next step, the same group of students were taught in accordance with CPC model for 88 and 86 hours respectively in college hours. Ten class tests each were taken and scores recorded. A standardized questionnaire was given to all 500 students after finishing with each curricular model and then the results were compared on SPSS 8.0 regarding their study trends, thinking abilities, intellectual skills and liking of CPC. Chi-square test was used to get significance values and percentages were used for the evaluation of differences. This study detected the positive effects of CPC model not only on study trends and thought process but also had the beneficial effects on learning potential of students in QMC where traditional curriculum was being followed for teaching students. When compared with traditional curricula, CPC model significantly ( p =methods to improve knowledge and intellectual skills e.g; group discussions, internet use, reading latest and relevant journals and visits to wards and concerned teachers.

Laboratory exercises are intended to illustrate concepts and add an active learning component to courses. Since 1980s, there has been a decline in animal laboratories in medical physiology courses. Other cost-effective non-aninmal alternatives are being sought. The present study was designed to find out the students' opinion regarding the animal versus computer lab and whether innovative teaching methodologies helped students achieve their goals. Opinions of 481 female in medical students of 2nd and 3rd year MBBS were included in the study. A questionnaire based on animal/computer based experiments and new teaching methodologies in physiology was voluntarily filled in by the students. Majority of students immensely benefited from both the animal lab and other teaching methodologies. Although computer based learning is considered effective in helping students acquire basic concepts, there is evidence that some students acquire a more thorough understanding of the material through more advanced and challenging experience of an animal laboratory. The fact that such labs as well various teaching methods offer distinct educational advantages should be taken into account when courses are designed.

Full Text Available Abstract OBJECTIVE To evaluate the effectiveness of teaching strategies used for development of critical thinking (CT in undergraduate nursing students. METHOD Systematic review with meta-analysis based on the recommendations of the Joanna Briggs Institute . Searches were conducted in the following databases: PubMed, CINAHL, EMBASE, Web of Science, SCOPUS, LILACS, Cochrane CENTRAL, PsycINFO, ERIC, and a database of theses from four continents. The initial selection and evaluation of studies and assessment of methodological quality was performed by two reviewers independently. RESULTS Twelve randomized clinical trials were included in the study. In the meta-analysis of the four studies included that evaluated the strategy of problem-based learning (PBL, compared to lectures, the effectiveness of PBL was demonstrated with statistical significance (SMD = 0.21 and 95% CI = 0.01 to 0.42; p = 0.0434 for the development of CT in undergraduate nursing students, and the studies were homogeneous (chi-square = 6.10, p = 0.106. CONCLUSION The effectiveness of PBL was demonstrated in the increase of overall CT scores. Further studies need to be conducted in order to develop, implement and evaluate teaching strategies that are guided in high methodological rigor, and supported in theoretical models of teaching and learning.

Assessment is a central component of course curriculums and is used to certify student learning, but it can also be used as a tool to improve teaching and learning. Many laboratory courses are structured such that there is only a grade for a particular laboratory, which limits the insights that can be gained in student learning. We developed a…

The aim of this study is to evaluate a teaching strategy designed to teach first-year undergraduate life sciences students at a research university how to learn to read authentic research articles. Our approach-based on the work done in the field of genre analysis and argumentation theory-means that we teach students to read research articles by teaching them which rhetorical moves occur in research articles and how they can identify these. Because research articles are persuasive by their very nature, we focused on the rhetorical moves that play an important role in authors' arguments. We designed a teaching strategy using cognitive apprenticeship as the pedagogical approach. It was implemented in a first-year compulsory course in the life sciences undergraduate program. Comparison of the results of a pretest with those of the posttest showed that students' ability to identify these moves had improved. Moreover, students themselves had also perceived that their ability to read and understand a research article had increased. The students' evaluations demonstrated that they appreciated the pedagogical approach used and experienced the assignments as useful. On the basis of our results, we concluded that students had taken a first step toward becoming expert readers. © 2014 E. B. Van Lacum et al.

Full Text Available Background: There is a worldwide shortage of qualified laboratory personnel to provide adequate testing for the detection and monitoring of diseases. In an effort to increase laboratory capacity in developing countries, new skills have been introduced into laboratory services. Curriculum revision with a focus on good laboratory practice is an important aspect of supplying entry-level graduates with the competencies needed to meet the current needs. Objectives: Gaps in application and problem-solving competencies of newly graduated laboratory personnel were discovered in Ethiopia, Tanzania and Kenya. New medical laboratory teaching content was developed in Ethiopia, Tanzania and Kenya using national instructors, tutors, and experts and consulting medical laboratory educators from the United States of America (USA. Method: Workshops were held in Ethiopia to create standardised biomedical laboratory science (BMLS lessons based on recently-revised course objectives with an emphasis on application of skills. In Tanzania, course-module teaching guides with objectives were developed based on established competency outcomes and tasks. In Kenya, example interactive presentations and lesson plans were developed by the USA medical laboratory educators prior to the workshop to serve as resources and templates for the development of lessons within the country itself. Results: The new teaching materials were implemented and faculty, students and other stakeholders reported successful outcomes. Conclusions: These approaches to updating curricula may be helpful as biomedical laboratory schools in other countries address gaps in the competencies of entry-level graduates.

To compare medical students' preference of smart phone television display (SPTD) to a slit-lamp teaching telescope (SLTT) in undergraduate clinical ophthalmology education. This is a randomized, crossover, comparative study. Pairs of medical students were randomly assigned to 2 teaching sessions using either SPTD first followed by SLTT or in reverse order. Students were asked to give feedback on the 2 teaching devices by answering 6 questions using a numeric rating score from 1 to 10. All participating students were sent the results of the study 1 month after the completion of the study and were asked to reflect upon the outcome. Thirty-eight students were recruited. The overall satisfaction scores were significantly higher for SPTD than SLTT (8.6 ± 1.4 vs 7.5 ± 1.0, p < 0.01). The students preferred SPTD compared with SLTT in terms of "visualization" (8.5 ± 1.4 vs 7.0 ± 1.3, p < 0.01), "ocular sign description" (8.4 ± 1.3 vs 7.2 ± 1.2, p < 0.01), "ocular anatomy understanding" (8.3 ± 1.2 vs 7.6 ± 1.2, p < 0.01), and "confidence in identifying clinical signs" (8.4 ± 1.2 vs 7.5 ± 1.2, p < 0.01). A larger proportion of the students gave higher scores to SPTD compared with SLTT in all questions. All students who responded to the follow-up questionnaire (n = 14) agreed with our interpretation of the data and would support the use of SPTD in undergraduate clinical ophthalmology teaching. Our study has demonstrated that the utility of SPTD as a teaching aid can significantly increase the satisfaction of undergraduate medical students during their ophthalmology attachment. It offers specific practical advantages in teaching medical students over the traditional SLTT. Copyright © 2017 Canadian Ophthalmological Society. Published by Elsevier Inc. All rights reserved.

The practice of RNA isolation in undergraduate experimental courses is rare because of the existence of robust, ubiquitous and stable ribonucleases. We reported here modifications to our original protocol for RNA isolation from plant tissues, including the recovery of nucleic acids by ethanol precipitation at 0 °C for 10 min and the assessment of RNA quality by visualizing the banding profile of the separated RNAs on a standard nondenaturing agarose gel to shorten the duration of the whole procedure and simplify the operation. As a result, the modified procedure, including RNA isolation and quality control analysis could be finished in 4 hr and divided into two sessions. Because endogenous ribonucleases released upon disruption of the organelles and vacuoles were effectively and quickly inactivated, measures were taken to protect RNA integrity throughout the whole procedure so that total RNA with high purity and integrity as well as an appropriate yield could be obtained by students. The RNA isolation protocol described here was simple, efficient, flexible, and low cost. Therefore, it is an ideal approach for undergraduates to learn about RNA techniques. The pedagogical approach of the correlation of experimental work with the rationale for the whole protocol described in this report is an effective way for undergraduates to improve their learning of the techniques of RNA isolation and analysis and the theories behind them, as well as experimental design and data analysis. © 2017 by The International Union of Biochemistry and Molecular Biology, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

While urban environments may lack the beauty of relatively pristine field sites, they can be used to deliver an effective demonstration of actual environmental damage. Students demanding applied field experiences from their undergraduate environmental science programs can be well served in urban settings. Here, we present strategies for integrating degraded urban systems into the undergraduate field experience. Urban locations provide an opportunity for a different type of local "field-work" than would otherwise be available. In the upper-level undergraduate Environmental Methods class, we relied on a National Park area located a 10-minute walk from campus for most field exercises. Activities included soil analysis, measuring stream flow and water quality parameters, dendrochronology, and aquatic microbe metabolism. In the non-majors class, we make use of our urban location to contrast water quality in parks and highly channelized urban streams. Students spend labs immersed in streams and wetlands heavily impacted by the urban runoff their city generates. Here we share lesson plans and budgets for field activities that can be completed during a class period of 2.5 hours with a $75 course fee, show how these activities help students gain quantitative competency.

Evaluation is an integral part of curriculum development in medical education. Given the peculiarities of bedside teaching, specific evaluation tools for this instructional format are needed. Development of these tools should be informed by appropriate frameworks. The purpose of this study was to develop a specific evaluation tool for bedside teaching based on the Stanford Faculty Development Program's clinical teaching framework. Based on a literature review yielding 47 evaluation items, an 18-item questionnaire was compiled and subsequently completed by undergraduate medical students at two German universities. Reliability and validity were assessed in an exploratory full information item factor analysis (study one) and a confirmatory factor analysis as well as a measurement invariance analysis (study two). The exploratory analysis involving 824 students revealed a three-factor structure. Reliability estimates of the subscales were satisfactory (α = 0.71-0.84). The model yielded satisfactory fit indices in the confirmatory factor analysis involving 1043 students. The new questionnaire is short and yet based on a widely-used framework for clinical teaching. The analyses presented here indicate good reliability and validity of the instrument. Future research needs to investigate whether feedback generated from this tool helps to improve teaching quality and student learning outcome.

Near-peer teaching involves more experienced students acting as tutors and has been widely used in anatomy education. This approach has many advantages for the learner due to the social and cognitive congruence they share with the teacher, however, the influence of distance between the teacher and learner on these congruences has yet to be explored. The aim of this study was to compare the attitudes and perceptions of the student learner towards neuroanatomy review sessions taught by either a senior medical student or a junior doctor. The students were randomly assigned to an allocated tutor. All tutors used standardized material and had access to identical resources. The type of allocated tutor was swapped between the two teaching sessions and 99 student feedback forms were collected in total. The rating for the overall quality of the teaching session was not significantly different between the junior doctors and senior medical students (P = 0.11). However, criteria closely relating to social and cognitive congruence such as "enjoyment of the session," "delivery of the teaching," and "was it a good use of time" were all rated significantly higher for the senior medical students (P distance along the near-peer teaching spectrum have an impact upon the student's perception of their learning experience. While all teachers were suitable role models it appears that junior doctors are too far removed from their own undergraduate experiences to share congruences with pre-clinical medical students. © 2013 American Association of Anatomists.

Because understanding the structure of biological macromolecules is critical to understanding their function, students of biochemistry should become familiar not only with viewing, but also with generating and manipulating structural representations. We report a strategy from a one-semester undergraduate biochemistry course to integrate use of structural representation tools into both laboratory and homework activities. First, early in the course we introduce the use of readily available open-source software for visualizing protein structure, coincident with modules on amino acid and peptide bond properties. Second, we use these same software tools in lectures and incorporate images and other structure representations in homework tasks. Third, we require a capstone project in which teams of students examine a protein-nucleic acid complex and then use the software tools to illustrate for their classmates the salient features of the structure, relating how the structure helps explain biological function. To ensure engagement with a range of software and database features, we generated a detailed template file that can be used to explore any structure, and that guides students through specific applications of many of the software tools. In presentations, students demonstrate that they are successfully interpreting structural information, and using representations to illustrate particular points relevant to function. Thus, over the semester students integrate information about structural features of biological macromolecules into the larger discussion of the chemical basis of function. Together these assignments provide an accessible introduction to structural representation tools, allowing students to add these methods to their biochemical toolboxes early in their scientific development. © 2013 by The International Union of Biochemistry and Molecular Biology.

The laboratory has been given a central role in physiology education, and teachers report that it is motivating for students to undertake experimental work on live animals or measuring physiological responses on the students themselves. Since motivation is a critical variable for academic learning and achievement, then we must concern ourselves with questions that examine how students engage in laboratory work and persist at such activities. The purpose of the present study was to investigate how laboratory work influences student motivation in physiology. We administered the Lab Motivation Scale to assess our students' levels of interest, willingness to engage (effort), and confidence in understanding (self-efficacy). We also asked students about the role of laboratory work for their own learning and their experience in the physiology laboratory. Our results documented high levels of interest, effort, and self-efficacy among the students. Correlation analyses were performed on the three motivation scales and exam results, yet a significant correlation was only found between self-efficacy in laboratory work and academic performance at the final exam. However, almost all students reported that laboratory work was very important for learning difficult concepts and physiological processes (e.g., action potential), as the hands-on experiences gave a more concrete idea of the learning content and made the content easier to remember. These results have implications for classroom practice as biology students find laboratory exercises highly motivating, despite their different personal interests and subject preferences. This highlights the importance of not replacing laboratory work by other nonpractical approaches, for example, video demonstrations or computer simulations.

Quiz-based and collaborative teaching strategies have previously been found to be efficient for the improving meaningful learning of physiology during lectures. These approaches have, however, not been investigated during laboratory exercises. In the present study, we compared the impact of solving quizzes individually and in groups with conventional teaching on the immediate learning during a laboratory exercise. We implemented two quizzes in a mandatory 4-h laboratory exercise on baroreflex physiology. A total of 155 second-year medical students were randomized to solve quizzes individually (intervention group I, n = 57), in groups of three to four students (intervention group II, n = 56), or not to perform any quizzes (control; intervention group III, n = 42). After the laboratory exercise, all students completed an individual test, which encompassed two recall questions, two intermediate questions, and two integrated questions. The integrated questions were of moderate and advanced difficulty, respectively. Finally, students completed an evaluation form. Intervention group I reached the highest total test scores and proved best at answering the integrated question of advanced difficulty. Moreover, there was an overall difference between groups for student evaluations of the quality of the teaching, which was highest for intervention group II. In conclusion, solving quizzes individually during a laboratory exercise may enhance learning, whereas solving quizzes in groups is associated with higher student satisfaction.
Background The aim of this study was to evaluate e-learning strategy in teaching Atraumatic Restorative Treatment (ART) to undergraduate and graduate students. The sample comprised 76 participants—38 dental students and 38 pediatric dentistry students—in a specialization course. To evaluate knowledge improvement, participants were subjected to a test performed before and after the course. Results A single researcher corrected the tests and intraexaminer reproducibility was calculated (CCI = 0.991; 95% IC = 0.975–0.996). All students improved their performances after the e-learning course (Paired t-tests p ART. Mature students perform better in this teaching modality when it is applied exclusively via distance learning. PMID:25034167

Regardless of discipline, a decades-long battle has ensued within nearly every classroom in higher education: instructors getting students to come to class prepared to learn. In response to this clash between teacher expectations and frequent student neglect, a group of four physics education researchers developed a reformed instructional strategy called Just-in-Time Teaching (JiTT). This dissertation investigates the following three areas: 1) the fidelity with which undergraduate physics instructors implement JiTT, 2) whether student performance predicts student perception of their instructor's fidelity of JiTT implementation, and 3) whether student perception of their instructor's fidelity of JiTT implementation correlates with student views of their physics course. A blend of quantitative data (e.g., students grades, inventory scores, and questionnaire responses) are integrated with qualitative data (e.g., individual faculty interviews, student focus group discussions, and classroom observations). This study revealed no statistically significant relationship between instructors who spent time on a predefined JiTT critical component and their designation as a JiTT user or non-user. While JiTT users implemented the pedagogy in accordance with the creators' intended ideal vision, many also had trouble reconciling personal concerns about their role as a JiTT adopter and the anticipated demand of the innovation. I recommend that this population of faculty members can serve as a JiTT model for other courses, disciplines, and/or institutions. Student performance was not a predictor of student perception instructor fidelity of JiTT implementation. Additionally, the majority of students in this study reported they read their textbook prior to class and that JiTT assignments helped them prepare for in-class learning. I found evidence that exposure to the JiTT strategy may correlate with a more favorable student view of their physics course. Finally, according to students

Exposure of undergraduate medical students to general practice and community healthcare services is common practice in the international medical curricula. Nevertheless, proponents of the hospital and biotechnology based paradigm, which is still dominant within the medical academic environment, question both the scope and the setting of this training procedure. Regarding the latter, the quality of teaching is often questioned in settings such as rural primary health centers, where health professionals have neither incentives nor accredited training skills. Therefore, the success of community based medical education depends substantially on the procedures implemented to involve non-academic staff as clinical teachers. This report describes the steps taken by the Aristotle University of Thessaloniki (AUTH) Medical School to establish and maintain a Rural Primary Health Care (PHC) Teaching Network in order to implement community oriented PHC and GP undergraduate medical education. A multi-professional teachers' network of healthcare staff, working in Rural Primary Health Centers, has been chosen, in order to expose students to the holistic approach of PHC. The enrollment of teachers to the Teaching Network was solely on a voluntary basis. The novelty of this procedure is that each professional is approached personally, instead through the Health Center (HC) that usually offers this service as a package in similar activities. In an attempt to attract health professionals committed to medical education, a self-selection procedure was adopted. Collaboration with the medical school was established but it was characterized by the School's inability to compensate teachers. A series of 'Training the Trainers' seminars were completed during the first implementation period in order to enhance the awareness of health professionals regarding undergraduate teaching in PHC; to present the educational needs of medical students; to expose them to the principles of medical teaching

The aim of this study was to evaluate e-learning strategy in teaching Atraumatic Restorative Treatment (ART) to undergraduate and graduate students. The sample comprised 76 participants-38 dental students and 38 pediatric dentistry students-in a specialization course. To evaluate knowledge improvement, participants were subjected to a test performed before and after the course. A single researcher corrected the tests and intraexaminer reproducibility was calculated (CCI = 0.991; 95% IC = 0.975-0.996). All students improved their performances after the e-learning course (Paired t-tests p < 0.001). The means of undergraduate students were 4.7 (initial) and 6.4 (final) and those of graduate students were 6.8 (initial) and 8.2 (final). The comparison of the final evaluation means showed a statistically significant difference (t-tests p < 0.0001). The e-learning strategy has the potential of improving students' knowledge in ART. Mature students perform better in this teaching modality when it is applied exclusively via distance learning.

Historically, different concepts of public health have influenced both the specific teaching in this field and its participation in general physician training. Starting from this assumption, the objective of this paper was to study how public health has been taught in undergraduate medical courses, focusing on structure and on how this has affected curriculum design in three universities in the State of Paraná, Brazil. Qualitative investigation developed at Universidade Federal do Paraná (UFPR), Universidade Estadual de Londrina (UEL) and Universidade Positivo (UnicenP). This study included a documentary analysis on pedagogical projects and on how these are actually experienced by those working on them. Eleven managers and 18 teachers were interviewed, as well as four groups of students that were formed in the three medical courses. Between 5 and 20% of Public Health topics were shown to be included in the curriculums, depending on the teaching strategies used. However, they were always set up within academic approaches that were strongly linked to healthcare services. This situation has been strengthened through the degree of progress made by the National Health System (Sistema Unico de Saúde, SUS) in both cities (Curitiba and Londrina). Regardless of the nature of the university, the administrative and academic setup of the course and of the different ways of incorporating teachers, Public Health is present and takes on considerable relevance for medical training, even if it does not constitute a linking thread within undergraduate medical courses.

The international world of higher education is changing with universities now offering students flexible delivery options that allow them to study away from campus and at a time convenient to them. Some students prefer on line learning while others prefer face to face contact offered through a traditional lecture and tutorial delivery modes. The response by many universities is to offer a blend of both. While online and blended mode of delivery may be suitable for some subjects there is little knowledge of the efficacy of blended learning models to teach evidence based practice and research (EBPR) to undergraduate midwifery students. EBPR is a challenging, threshold level subject upon which deeper knowledge and skills are built. This paper describes the design, delivery, and evaluation of an undergraduate EBPR course delivered in blended mode to first year midwifery students. Components of the blended learning innovation included: novel teaching strategies, engaging practical activities, role play, and e-learning strategies to maintain engagement. University-based course evaluation outcomes revealed very positive scores and the course was rated within the top ten percent of all courses offered within the Health Group at the host University.

Problem-based learning (PBL) is a pedagogical approach based on recent advances in cognitive science research on human learning. PBL has been used in medical schools for many years. This paper describes the application of PBL in undergraduate courses and discusses the specific needs of this environment. Practical information and guidance are given on how to develop a challenging problem, how to ensure coverage of syllabus topics, how to structure the discussions, and how to evaluate the progress of the course. The paper describes an implementation of PBL methodologies in an undergraduate science course. In this course, students work with a voluntary environmental advocacy group, the Upper Chattahoochee RiverKeeper, to monitor the quality of water in the Chattahoochee watershed. Students learn experimental analytical chemistry techniques and problem-solving skills in this context. A PBL classroom is organized around collaborative problem-solving activities, which provide a context for learning and discovery. Students show enthusiasm and motivation to learn, and they achieve a deeper understanding of the material because it is information they have learned in a context of an interesting problem. PBL also provides them with an opportunity to acquire effective problem-solving techniques and to improve their communication skills and their ability to work in cooperative groups.

Full Text Available This study aimed to analyze the teaching strategy development in undergraduate courses in HEI Management of Itajaí Valley from the perspective of students and teachers. Studies of strategy approaches have been reviewed, as well as methods and techniques of teaching strategy and the role of strategy teachers. A qualitative research has been performed based on a collective case study with students (focus groups and teachers (in depth interviews of a private and a public institution, in addition to a documentary research. Regarding the body of knowledge in strategy, it has been identified the presence of classical approaches. Both HEI use books from national and international classic authors. In relation to teaching methods, the HEI “A” uses the interaction between the theory of strategic planning and the application in a company, whereas the HEI “B” gives preference to theoretical discussions. Regarding the typification of conduct, it has been noticed a pattern of action of teachers regarding the collection of reading and on-time delivery of activities. The individuals (strategy teachers have specific actions, which are typified as forms of action, i.e. patterns collectively targeted to teach, to impart or disseminate knowledge of strategy.

Acid/base homeostasis is one of the most difficult subdisciplines of physiology for medical students to master. A different approach, where theory and practice are linked, might help students develop a deeper understanding of acid/base homeostasis. We therefore set out to develop a laboratory...... exercise in acid/base physiology that would provide students with unambiguous and reproducible data that clearly would illustrate the theory in practice. The laboratory exercise was developed to include both metabolic acidosis and respiratory alkalosis. Data were collected from 56 groups of medical...

Abstract A course-based undergraduate research experience (CURE) spanning three semesters was introduced into freshman and sophomore biology classes, with the hypothesis that participation in a CURE affects skills in research, communication, and collaboration, which may help students persist in science. Student research projects were centered on the hypothesis that nicotine and caffeine exposure during early development affects gastrulation and heart development in zebrafish. First, freshmen generated original data showing distinct effects of embryonic nicotine and caffeine exposure on zebrafish heart development and function. Next, Cell Biology laboratory students continued the CURE studies and identified novel teratogenic effects of nicotine and caffeine during gastrulation. Finally, new freshmen continued the CURE research, examining additional toxicant effects on development. Students designed new protocols, made measurements, presented results, and generated high-quality preliminary data that were studied in successive semesters. By implementing this project, the CURE extended faculty research and provided a scalable model to address national goals to involve more undergraduates in authentic scientific research. In addition, student survey results support the hypothesis that CUREs provide significant gains in student ability to (1) design experiments, (2) analyze data, and (3) make scientific presentations, translating into high student satisfaction and enhanced learning.
