    DeKorver, Brittland K.

    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.

  2. EDITORIAL: Student undergraduate laboratory and project work

    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

    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.

    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.

    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.

    Alessio Gaspar

    2007-06-01

    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.

    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.

    2011-06-01

    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.

    2018-03-01

    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.

  20. Quality of Undergraduate Physics Students' Written Scientific Arguments: How to Promote Students' Appropriation of Scientific Discourse in Physics Laboratory Reports?

    Science.gov (United States)

    Aydeniz, Mehmet; Yeter-Aydeniz, Kubra

    2015-03-01

    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.

    2015-08-01

    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. Editor's Note:The ASM advocates that students must successfully demonstrate the ability to explain and practice safe

    2015-12-01

    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.

    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.

    1996-02-01

    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

    Walker, Joi Phelps

    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). There was

  12. Climate-Literacy Laboratory Exercises for Undergraduate Students in an Introductory Weather and Climate Course

    2012-12-01

    A suite of NASA-sponsored, Web-based exercises are in development for an introductory weather and climate course at Georgia State University (GSU) to improve climate literacy among undergraduate students. An extremely small percentage of the students are STEM majors. The exercises make extensive use of NASA resources and are guided in part by the concepts in Climate Literacy: The Essential Principles of Climate Science. At least two thousand undergraduate students have completed a majority of the exercises over the past two years. Nine of the twelve exercises in the course are connected strongly to climate literacy. The topics of those nine exercises are as follows: (1) Solar Irradiance, (2) Stratospheric Ozone, (3) Tropospheric Air, (4) The Carbon Cycle, (5) Global Surface Temperature, (6) Glacial-Interglacial Cycles, (7) Temperature Changes during the Past Millennium, (8) Climate & Ecosystems, and (9) Current & Future Climate Change. Two of the exercises (Tropospheric Air and The Carbon Cycle) make use of carbon dioxide (CO2) measurements made by students themselves and by a stationary CO2 monitor at GSU. The three remaining exercises, The Hadley Cell, Atlanta Weather, and Air Pollution, are less connected to multiple climate-literacy concepts; nonetheless, they provide a more complete experience for the students in the understanding of climate processes, differences between weather and climate, and human impacts on the atmosphere. All exercises are based on an inquiry-based learning cycle (i.e. 7 Es) and require substantial amounts of engagement, applied thinking, and critical thinking by the students. Not only do students become knowledgeable about the essential principles of climate change, especially global warming, but extensive use of geographical-information software and hand-held measurement devices has provided students with training in geography and technology. Student attitudes towards the labs were gathered via an on-line, anonymous survey from

    This study explored how undergraduate students in a new problem-centered General Chemistry Laboratory curriculum achieved cognitive growth. The new curriculum had three instructional segments: the highly-structured, semi-structured, and open-ended segments. The pedagogical approaches adopted were expository, guided-inquiry, and open-inquiry styles, respectively. Sixty-seven first-year undergraduate students who enrolled in the course in Spring semester, 2000, at Columbia University and three Ph.D.-level chemistry experts were included in the study. A qualitative approach was used including data collection through "think-aloud" problem solving; however, quantitative data such as test scores were also used. The findings from this study confirmed that chemistry experts possessed sophisticated and domain-specific conceptual knowledge structures; they mobilized and applied conceptual knowledge in conjunction with use of heuristics, tacit knowledge, and experience in authentic problem solving. They validated the new curriculum design in preparing students for inquiry-type of problem solving. For novices, solving of semi-structured before ill-structured problems had a positive effect on the solvers' chance of success in solving the latter type of problems as their abilities to mobilize and apply conceptual knowledge and use effective strategies appeared to be critical for successful problem solving. Students in the new course curriculum had grown cognitively as evidenced by their performance on the Case Study projects and Final Examination. High academic achievers were found to perform well independently while the medium and relatively low academic achievers should benefit from sustained and intensive instruction. It is proposed that ill-structured problems should be used to assess and identify the best from the better students. Finally, it was found that no significant change in students' attitudes had resulted from their curriculum experience. Gender and cognitive style

  14. Student-Driven Engagement: An Interdisciplinary-Team Research-Learning Renewable Energy Laboratory Experience for Undergraduates

    Science.gov (United States)

    Tuominen, Mark

    How does engagement and deep learning happen? Every science department seeks to cultivate an excellent level of scientific skills and knowledge in its undergraduate students. Yet, this is not sufficient to thrive as a professional. Engaging directly in real-world challenges can foster a professional attitude: a high level of self-efficacy, a genuine sense of relevance, and proactivity. This talk will describe pedagogical developments of a junior-year renewable energy laboratory course at the University of Massachusetts Amherst that is part of a four-year Integrated Concentration in Science (iCons) program. Over the four years, the interdisciplinary iCons students-from 24 various majors-work through case studies, selection and analysis of real-world problems, inception and development of potential solutions, integrative communication, experimental practice, and capstone research. The team dynamic is a central aspect of the experience, yielding significant educational and developmental benefits. The third-year energy course uses adopts a culture of a small vibrant R and D company (I3E - ``Energy, Powered By Intelligence''), in which every person in the course has a vital responsibility and creative resourcefulness must be employed in the project work. The course emphasizes the practice of using reflection and redesign, as a means of generating better solutions and embedding the practice of learning in a real-world context. This work is supported in part by NSF Grant DUE-1140805.

  15. Undergraduate Organic Chemistry Laboratory Safety

    Science.gov (United States)

    Luckenbaugh, Raymond W.

    1996-11-01

    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.

    2017-04-01

    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.

    2015-12-01

    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.

  10. Measuring meaningful learning in the undergraduate chemistry laboratory

    Science.gov (United States)

    Galloway, Kelli R.

    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.

    2013-01-01

    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.

    Healy, Frank G; Livingstone, Kevin D

    2010-09-01

    We report a thematic sequence of directed inquiry-based labs taking students from bacterial mutagenesis and phenotypic identification of their own self-created mutant, through identification of mutated genes by biochemical testing, to verification of mutant alleles by complementation, and finally to mutant allele characterization by DNA sequence analysis. The lab utilizes UV mutagenesis with wild-type Escherichia coli and a UV-sensitive isogenic derivative optimized for undergraduate use. The labs take advantage of the simplicity of E. coli in a realistic genetic investigation using safe UV irradiation methods for creation and characterization of novel mutants. Assessment data collected over three offerings of the course suggest that the labs, which combine original investigation in a scientifically realistic intellectual environment with learned techniques and concepts, were instrumental in improving students' learning in a number of areas. These include the development of critical thinking skills and understanding of concepts and methods. Student responses also suggest the labs were helpful in improving students' understanding of the scientific process as a rational series of experimental investigations and awareness of the interdisciplinary nature of scientific inquiry.

    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.

    2017-01-01

    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.

    Directory of Open Access Journals (Sweden)

    Vianna José F.

    1999-01-01

    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.

    Wilder, A.; Feeley, T.; Michelfelder, G.

    2011-12-01

    Traditionally, the roles of field experiences in geoscience teaching have come from experienced instructors and researchers with a dedicated interest in how students learn. In this presentation we provide the opposite perspective; that of an undergraduate student at the beginning of her research career. We discuss the benefits and challenges associated with the initial field work and extend our discussion to include subsequent analytical-based laboratory studies. At Montana State University we are addressing key questions related to magma generation and differentiation at three volcanoes in the Central Andes. These are Volcan Uturuncu in southwest Bolivia and the Lazufre system consisting of Lastarria volcano and Cordon del Azufre in Chile and Argentina. To address these issues students collected rock samples and mapped lava flows in the field during the past two Spring Semesters. Upon return to campus the students prepared the samples for whole rock and mineral analyses, followed by travel to and work in external laboratories analyzing and collecting high precision geochemical data. The benefits these experiences provide include the following. First, due to the localities of the field sites, students become familiar with the difficult logistics associated with planning and performing field work in remote localities. Second, in performing the field work, students gain an appreciation of scale and exposure; topics not typically addressed in standard course work. Third, through close interaction with internal and external faculty, graduate students, and professional geologists, undergraduate students build strong relationships with scientists in the area of their interests. Fourth, by acquiring and interpreting high quality field and analytical data, they learn in-depth about modern philosophies, technologies, and data in the geosciences, providing them with skills and experiences that will be of value in their future careers or graduate work. They also learn how to

    Full Text Available The knowledge of scientific method provides stimulus and development of critical thinking and logical analysis of information besides the training of continuous formulation of hypothesis to be applied in formal scientific issues as well as in everyday facts. The scientific education, useful for all people, is indispensable for the experimental science students. Aiming at the possibility to offer a systematic learning of the scientific principles, we developed a undergraduate course designed to approximate the students to the procedures of scientific production and publication. The course was developed in a 40 hours, containing two modules: I. Introducing Scientific Articles (papers and II. Writing Research Project. The first module deals with: (1 the difference between scientific knowledge and common sense; (2 scientific methodology; (3 scientific publishing categories; (4 logical principles; (5 deduction and induction approach and (6 paper analysis. The second module includes (1 selection of problem to be solved by experimental procedures; (2 bibliography revision; (3 support agencies; (4 project writing and presentation and (5 critical analysis of experimental results. The course used a Collaborative Learning strategy with each topic being developed through activities performed by the students. Qualitative and quantitative (through Likert questionnaires evaluation were carried out in each step of the course, the results showing great appreciation by the students. This is also the opinion of the staff responsible for the planning and development of the course, which is now in its second and improved version.

    Rassool, Goolam Hussein; Rawaf, Salman

    To determine the predominant learning style preferences of undergraduate nursing students. A demographic questionnaire and Honey and Mumford's (2000a) learning styles questionnaire were administered to a purposive sample of 136 students. A response rate of 81% (110) was obtained. The results are congruent with U.K. studies, which show that the reflector is the preferred learning style of undergraduate nursing students. A 'dual' learning style category was also identified. A mismatch between teaching style and the learning styles of students has been found to have serious consequences. A variety of modes of teaching and learning should be used to meet the learning needs of students.

    George, Tracy P; DeCristofaro, Claire

    2016-07-01

    It is important for nursing students to become comfortable with accessing point-of-care technology to support provision of safe, evidence-based care to patients. Smartphone applications (apps) were introduced into community screening settings in a first-semester undergraduate nursing health assessment course. The apps provided information about body mass index, as well as United States Preventive Services Task Force-recommended preventive services using the Agency for Health Research and Quality electronic preventive services selector app. Classroom activities prepared students using mock cases and real data, and evidence-based guidelines were used when counseling patients about individual results. Smartphone apps were well accepted by students and allowed students to transfer learning from the classroom and laboratory to the community setting. Smartphone apps promote active learning and the long-term retention of knowledge. This community-based activity supports the validity of independent health promotion activities in nursing practice.

    Pham, Kara; Romeo, Russell D

    2012-01-01

    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.

    2017-01-01

    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.

  17. Practicing biology: Undergraduate laboratory research, persistence in science, and the impact of self-efficacy beliefs

    Science.gov (United States)

    Berkes, Elizabeth

    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

  18. Discovery of Escherichia coli CRISPR sequences in an undergraduate laboratory.

    Militello, Kevin T; Lazatin, Justine C

    2017-05-01

    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.

  19. Using Capillary Electrophoresis to Determine the Purity of Acetylsalicylic Acid Synthesized in the Undergraduate Laboratory

    Science.gov (United States)

    Welder, Frank; Colyer, Christa L.

    2001-11-01

    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.

  8. Development of sensorial experiments and their implementation into undergraduate laboratories

    Science.gov (United States)

    Bromfield Lee, Deborah Christina

    "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

    This study evaluates the self-esteem of undergraduate students of nursing, that through a workshop developed mechanisms for improving their self-esteem, considering that this is the most propitious time for students to multiply health care actions. the research was carried out with 156 undergraduate students of the third year. Socio-drama techniques of Neurolinguistics were used and the evaluation was done according to Minayo. It was possible to observe that students usually confuse self-esteem and self-image, and that both are stereotyped for for men and women. As nurses are always worried about the client/patient's life quality, they neglect themselves. In this case, the Workshops were essential for the students to rescue interior knowledge about themselves, and to realize that in order to take good care of clients/patients, they must be physically and psychologically healthy.

    Masters Students are major stakeholders in undergraduate medical education but their contribution has not been documented in Uganda. The aim of the study was to explore and document views and experiences of undergraduate students regarding the role of masters students as educators in four Ugandan medical schools. This was a cross-sectional descriptive study using qualitative data collection methods. Eight Focus Group Discussions were conducted among eighty one selected preclinical and clinical students in the consortium of four Ugandan medical schools: Mbarara University of Science and Technology, Makerere College of Health Sciences, Gulu University and Kampala International University, Western Campus. Data analysis was done using thematic analysis. Participants' privacy and confidentiality were respected and participant identifiers were not included in data analysis. Undergraduate students from all the medical schools viewed the involvement of master's students as very important. Frequent contact between masters and undergraduate students was reported as an important factor in undergraduate students' motivation and learning. Despite the useful contribution, master' students face numerous challenges like heavy workload and conflicting priorities. According to undergraduate students in Ugandan medical schools, involvement of master's students in the teaching and learning of undergraduate students is both useful and challenging to masters and undergraduate students. Masters students provide peer mentorship to the undergraduate students. The senior educators are still needed to do their work and also to support the master's students in their teaching role.

    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.

    2010-10-01

    Lessons learned during the first offering of a lab component of an intermediate astrophysics course at the University of Wisconsin-River Falls are discussed. The course enrolled students from a variety of majors. Students worked in mixed-gender, mixed-major collaborative groups. They explored cosmic rays through hands-on, inquiry-based activities that took them from classic, fundamental discoveries to open-ended questions of their own design. We find that students divided their labor and brought the various parts of their research project together with little or no discussion regarding the various pieces and how they inform each other. Aspects of the lab design helped disrupt some typical gender dynamics in that men did not dominate group discussions. However, men did dominate the hands-on activities of the lab.

    2004-01-01

    Although the literature on both academic dishonesty and scientific misconduct is extensive, research on academic dishonesty has focused on quizzes, exams, and papers, with the virtual exclusion of the classroom laboratory. This study examined the distinctions undergraduate chemistry majors made between academic dishonesty in the classroom laboratory and scientific misconduct in the research laboratory. Across the spectrum of undergraduate chemistry courses, from the introductory course for first-semester chemistry majors to the capstone course in instrumental analysis, we noted that students believe the classroom lab is fundamentally different from a research or industrial lab. This difference is so significant that it carries over into students' perceptions of dishonesty in these two environments.

  19. Undergraduate medical research: the student perspective

    2010-09-01

    Full Text Available Background: Research training is essential in a modern undergraduate medical curriculum. Our evaluation aimed to (a gauge students’ awareness of research activities, (b compare students’ perceptions of their transferable and research-specific skills competencies, (c determine students’ motivation for research and (d obtain students’ personal views on doing research. Methods: Undergraduate medical students (N=317 completed a research skills questionnaire developed by the Centre for Excellence in Teaching and Learning in Applied Undergraduate Research Skills (CETL-AURS at Reading University. The questionnaire assessed students’ transferable skills, research-specific skills (e.g., study design, data collection and data analysis, research experience and attitude and motivation towards doing research. Results: The majority of students are motivated to pursue research. Graduate entrants and male students appear to be the most confident regarding their research skills competencies. Although all students recognise the role of research in medical practice, many are unaware of the medical research activities or successes within their university. Of those who report no interest in a career incorporating research, a common perception was that researchers are isolated from patients and clinical practice. Discussion: Students have a narrow definition of research and what it entails. An explanation for why research competence does not align more closely with research motivation is derived from students’ lack of understanding of the concept of translational research, as well as a lack of awareness of the research activity being undertaken by their teachers and mentors. We plan to address this with specific research awareness initiatives.

    2017-02-01

    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.

    Full Text Available Thelma Quince, Pia Thiemann, John Benson, Sarah Hyde Primary Care Unit, Department of Public Health and Primary Care, Institute of Public Health, University of Cambridge, Cambridge, UK Abstract: Empathy is important to patient care. It enhances patients’ satisfaction, comfort, self-efficacy, and trust which in turn may facilitate better diagnosis, shared decision making, and therapy adherence. Empathetic doctors experience greater job satisfaction and psychological well-being. Understanding the development of empathy of tomorrow's health care professionals is important. However, clinical empathy is poorly defined and difficult to measure, while ways to enhance it remain unclear. This review examines empathy among undergraduate medical students, focusing upon three main questions: How is empathy measured? This section discusses the problems of assessing empathy and outlines the utility of the Jefferson Scale of Empathy – Student Version and Davis's Interpersonal Reactivity Index. Both have been used widely to assess medical students' empathy. Does empathy change during undergraduate medical education? The trajectory of empathy during undergraduate medical education has been and continues to be debated. Potential reasons for contrasting results of studies are outlined. What factors may influence the development of empathy? Although the influence of sex is widely recognized, the impact of culture, psychological well-being, and aspects of undergraduate curricula are less well understood. This review identifies three interrelated issues for future research into undergraduate medical students' empathy. First, the need for greater clarity of definition, recognizing that empathy is multidimensional. Second, the need to develop meaningful ways of measuring empathy which include its component dimensions and which are relevant to patients' experiences. Medical education research has generally relied upon single, self-report instruments, which have

    Purpose Physicians play an important leadership role in the management and governance of the healthcare system. Yet, many physicians lack formal management and leadership training to prepare them for this challenging role. This Viewpoint article argues that leadership concepts need to be introduced to undergraduate medical students early and throughout their medical education. Design/methodology/approach Leadership is an integral part of medical practice. The recent inclusion of "Leader" competency in the CanMEDS 2015 represents a subtle but important shift from the previous "manager" competency. Providing medical students with the basics of leadership concepts early in their medical education allows them to integrate leadership principles into their professional practice. Findings The Faculty of Medicine at the Memorial University of Newfoundland (MUN) has developed an eight-module, fully online Physician Leadership Certificate for their undergraduate medical education program. This program is cited as an example of an undergraduate medical curriculum that offers leadership training throughout the 4 years of the MD program. Originality/value There are a number of continuing professional development opportunities for physicians in the area of management and leadership. This Viewpoint article challenges undergraduate medical education programs to develop and integrate leadership training in their curricula.

  4. Undergraduate paramedic students cannot do drug calculations

    Eastwood, Kathryn; Boyle, Malcolm J; Williams, Brett

    2012-01-01

    BACKGROUND: Previous investigation of drug calculation skills of qualified paramedics has highlighted poor mathematical ability with no published studies having been undertaken on undergraduate paramedics. There are three major error classifications. Conceptual errors involve an inability to formulate an equation from information given, arithmetical errors involve an inability to operate a given equation, and finally computation errors are simple errors of addition, subtraction, division and multiplication. The objective of this study was to determine if undergraduate paramedics at a large Australia university could accurately perform common drug calculations and basic mathematical equations normally required in the workplace. METHODS: A cross-sectional study methodology using a paper-based questionnaire was administered to undergraduate paramedic students to collect demographical data, student attitudes regarding their drug calculation performance, and answers to a series of basic mathematical and drug calculation questions. Ethics approval was granted. RESULTS: The mean score of correct answers was 39.5% with one student scoring 100%, 3.3% of students (n=3) scoring greater than 90%, and 63% (n=58) scoring 50% or less, despite 62% (n=57) of the students stating they ‘did not have any drug calculations issues’. On average those who completed a minimum of year 12 Specialist Maths achieved scores over 50%. Conceptual errors made up 48.5%, arithmetical 31.1% and computational 17.4%. CONCLUSIONS: This study suggests undergraduate paramedics have deficiencies in performing accurate calculations, with conceptual errors indicating a fundamental lack of mathematical understanding. The results suggest an unacceptable level of mathematical competence to practice safely in the unpredictable prehospital environment. PMID:25215067

    Warland, Jane; McKellar, Lois; Diaz, Monica

    2014-11-01

    Assertiveness can be defined as an interpersonal behaviour that promotes the fact all people in a relationship are equally important. All health professionals including midwives must work with and care for people. At times this will include facilitating interactions that require skilful negotiation and assertiveness. Yet embedding assertiveness education into undergraduate midwifery curricula has not been widely adopted. This paper explores one method of delivering assertiveness training in an undergraduate midwifery course and provides comment on the effectiveness of this strategy in developing assertiveness skills in a cohort of undergraduate midwifery students. We used an assertiveness survey which was administered immediately before and 3-4 months after an assertiveness training workshop. All students (n = 55) attending the training day were invited to participate. Of these 41 (77% response) chose to participate in the pre intervention survey and 32 participated (9 students lost to follow-up) in the follow up survey. There was an overall improvement in self-perceived assertiveness scores following the assertiveness training workshop. These findings provide encouraging evidence that educational institutions that offer specific and targeted assertiveness education will be rewarded with more assertive graduates.

    Academic ethical awareness is an important aspect especially for nursing students who will provide ethical nursing care to patients in future or try to tread the path of learning toward professional acknowledgement in nursing scholarship. The purpose of this study was to explore academic ethical awareness and its related characteristics among undergraduate nursing students. This study commenced the survey with cross-sectional, descriptive questions and enrolled convenient samples of 581 undergraduate nursing students from three universities in South Korea. It was investigated with structured questionnaires including general characteristics and academic ethical awareness related. Ethical considerations: This study was reviewed and approved by the Institutional Review Board at National University. Academic ethical awareness was the highest regarding behaviors violating the respect or confidentiality of patients and cheating on exams, while it was the lowest for inappropriate behaviors in class. From the result of general characteristics difference, male students showed higher score than female students in relative; first-year students showed higher score than other year students; the higher score was rated from students who were highly satisfied with their major than the other not satisfied with their major; and students with low academic stress showed higher ethical awareness score than persons with higher stress. Personal behaviors were rated with low ethical awareness in relative, but items related to public rules and actual effects on patients or others were rated with higher score. Nursing satisfaction and academic stress are main factors on ethical awareness. To improve overall ethical awareness level of nursing students, it is required to provide more education about the importance of personal behaviors in class and need to improve the understanding of how it will be connected with future situation and effect.

  18. Transforming the Learning Environment of Undergraduate Physics Laboratories to Enhance Physics Inquiry Processes

    Directory of Open Access Journals (Sweden)

    Gregory P. Thomas

    2017-04-01

    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

    Few empirical studies have been undertaken on the communication styles of specific health-related disciplines. The objective of this study is to identify the communication styles of undergraduate health students at an Australian university. A cross-sectional study using a paper-based version of the Communicator Style Measure (CSM) was administered to a cohort of students enrolled in eight different undergraduate health-related courses. There were 1459 health students eligible for inclusion in the study. 860 students (response rate of 59%) participated in the study. Participants overall preferred the Friendly and Attentive communicator styles and gave least preference to the Contentious and Dominant styles. There was considerable similarity between participants from each of the health-related courses. There was no statistical difference in relation to communicator styles between the age of the participant or the year level they were enrolled in. These results show a preference for communicator styles which are facilitative of a client-centred approach, empathetic, and positive with interpersonal relationships. The lack of significant difference in communicator styles by year level further suggests that people disposed to such communicator styles are drawn to these health-related courses, rather than the specific field of study affecting their style.

    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

    Full Text Available Creativity is an important human faculty in several performance areas, including the work of a psychologist. This article aimed to describe creativity in a group of Psychology undergraduate students in order to verify whether their professional development fosters creative potential. The study comprised 75 students, equally distributed in three groups from the first, fifth and tenth terms, aged 18 to 59, who were submitted to the Verbal TTCT (Torrance Test of Creative Thinking: Thinking Creatively with Words, following technical specifications of this tool. Further to test evaluation, results of the three groups were statistically compared and the main results showed higher creativity index in senior students, mainly regarding Fluency – ability to produce a large number of ideas, and Originality – ability to produce new and infrequent ideas.

  8. Does the Pedagogy for the Teaching of First Year Undergraduate Laboratory Practicals Still Meet the Needs of the Curriculum?

    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

    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.

    Zentz, Suzanne E; Brown, Janet M; Schmidt, Nola A; Alverson, Elise M

    2009-01-01

    J. Cranmer and C. Lajkowicz (1989) faced the challenge of securing student clinical experiences with healthy prenatal clients. They identified that lack of access to pregnant women, limited number of faculty, and large numbers of students contributed to problems in meeting select course objectives. Little has changed since then. This article describes a clinical experience, known as "Prenatal Showers," where undergraduate nursing students, implementing the teacher role, provide community-based prenatal education in the context of a baby shower. Student groups address educational topics identified by community partners. After student presentations, feedback from prenatal clients is analyzed. Lessons learned include selecting appropriate community partners, clearly articulating academic and community needs, and obtaining seed money to initiate the program. Prenatal Showers are most successful when community partners possess open lines of communication, an accessible population, an appreciation for the contributions made by students, and a willingness to share responsibility for their supervision. Prenatal Showers offer different advantages from traditional maternal-child clinical experiences because students gain experiences with prenatal clients from diverse backgrounds and engage in community-based nursing. The community benefits because educational needs of prenatal clients are met. Strong community partnerships benefit faculty by making clinical placements more accessible and reducing faculty workload.

  12. Assessing Undergraduate Curriculum Through Student Exit Vectors

    Science.gov (United States)

    Keane, C. M.; Gonzales, L.; Martinez, C.

    2008-12-01

    One aspect of assessing the undergraduate curriculum is recognizing that the exit vector of the student is a metric in the absence of a structured assessment program. Detailed knowledge across all geosciences departments regarding the disposition of their recent baccalaureate recipients has been at best inconsistent, and in the case of about half of geoscience programs, non-existent. However, through examining of multiple datasets, a pattern of disposition of geosciences BS recipients emerges, providing a snapshot of the system- wide response to the system-wide "average" program. This pattern can also be juxtaposed against several frameworks of desired skill sets for recent graduates and the employment sectors likely to hire them. The question remains is can one deduce the effectiveness of the undergraduate program in placing graduates in their next step, whether in graduate school or the workplace. Likewise, with an increasing scrutiny on the "value" of an education, is the resulting economic gain sufficient for the student, such that programs will be viewed as sustainable. A factor in answering this question is the importance of the undergraduate program in the ultimate destination of the professional. Clear pathways exist for "optimal" schools for the production of new faculty and new industry professionals, but is it possible to identify those trends further up the educational pipeline? One major mechanism to examine the undergraduate program effectiveness related to exit vectors is to look at hiring trends witnessed related to markedly different program structures, such as those at universities outside of the United States. Rectifying academic programs between the United States and other national systems is often a challenge, but even given the substantial differences between depth of technical knowledge and breadth of education across these programs, in the end, the sum product is often viewed as roughly comparable. This paper will look at end

  14. Influence of study approaches and course design on academic success in the undergraduate anatomy laboratory.

    Science.gov (United States)

    Eleazer, Courtney D; Scopa Kelso, Rebecca

    2018-01-04

    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.

    Empathy and absence of prejudice and stigma are instrumental in facilitating effective nurse-patient relations. This study assessed empathy levels and regard for specific medical conditions in undergraduate nursing students. A cross-sectional study was undertaken using paper-based versions of the Jefferson Scale of Physician Empathy (JSPE) and Medical Condition Regard Scale (MCRS), along with a brief set of demographic questions. Participants reported good empathy levels on JSPE. Attitudes towards intellectual disability, chronic pain, acute mental illness and terminal illness rated well on MCRS. Attitudes towards substance abuse, however, were lower. There were no significant differences between age groups, gender or year level of study. Overall results of this study were positive. Nursing students demonstrated acceptable empathy levels. Attitudes towards patients who abuse substances highlight an area that needs both further exploration and addressing. Attitudes towards mental health diagnoses were particularly favourable given that these often attract stigma and negative attitudes. © 2012 Blackwell Publishing Asia Pty Ltd.

    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.

    Highly added sugar diets have been associated with various health problems such as dental caries, dyslipidemia, obesity and poor quality of life. Unfortunately, sugar consumption, especially sucrose, has increased continuously worldwide. The purpose of the study was to examine sources of sugar consumption and amount of added sucrose consumed in Thai undergraduate students. This study was carried out at Khon Kaen University, Thailand, between the years 2004-2005. A complete 3-day record of items and amounts of sweet consumption were obtained from 202 individuals--38 male and 164 female students. Added sucrose content of each sweetened food and drinks referred to in the record was determined by an enzymatic method. Mean intakes of sucrose were calculated from the sucrose content. The average of sucrose consumption in all subjects was 69+/-38 g/day, ranged from 4 to 182 g/day or 17 teaspoons of added sucrose per day. This amount accounted for 13.8% of total daily energy intake. There was a record of 337 kinds of sweetened foods and drinks found. The major source of added sucrose consumption was sweetened beverage, which was consumed 118 g/day averagely, or 60% of daily sugar consumption. Intake of sucrose per day in both male and female was not statistically difference, neither among different BMI groups. Intake of added sugar in the students was higher than the recommendation of the World Health Organization. These data would be helpful in a health promotion campaign aimed at a reduction of sugar consumption in Thai undergraduate students.

    Full Text Available INTRODUCTION: Medical training is highly stressful particularly for those who are beginning their medical education. The present study was undertaken to find out the level of stress, hypertension and its etiological factors among undergraduate medical students. METHOD: One hundred and seventeen undergraduate medical students between 17-21 years of age got examined for blood pressure and stress level. Twelve hypertensives selected from the above subjects and twenty normotensives underwent cold pressure test to assess autonomic reactivity to laboratory induced stress. RESULTS: 10.25% of the subjects were found to be hypertensive and 6.83% pre hypertensive. On the stress scale 53% had mild stress, 7% showed moderate stress while none had stress as a major problem. There was no correlation between BP and stress score. On CPT, BP increased significantly in both the hypertensive and normotensive group but came back to basal levels within 5 minutes indicating normal autonomic response. Rise of BP was higher in hypertensive group. The diastolic and mean BP increased significantly on CPT in subjects having family history of hypertension. The subjects taking more of junk and oily foods had a higher systolic BP. Forty percent of normotensive subjects had more than 20 mm Hg rise in systolic BP on CPT. CONCLUSIONS: Adolescents must be routinely screened to detect asymptomatic hypertension. Advice on risk factor modification by appropriate lifestyle changes may prevent long term effects of hypertension on target organs. Keywords: autonomic reactivity, blood pressure, cold pressor test, medical students, stress.

    The Undergraduate Student Instrumentation Project (USIP) is a NASA program to engage undergraduate students in rigorous scientific research, for the purposes of innovation and developing the next generation of professionals for an array of fields. The program is student led and executed from initial ideation to research to the design and deployment of scientific payloads. The University of Houston has been selected twice to participate in the USIP programs. The first program (USIP_UH I) ran from 2013 to 2016. USIP_UH II started in January of 2016, with funding starting at the end of May. USIP_UH I (USIP_UH II) at the University of Houston was (is) composed of eight (seven) research teams developing six (seven), distinct, balloon-based scientific instruments. These instruments will contribute to a broad range of geophysical sciences from Very Low Frequency recording and Total Electron Content to exobiology and ozone profiling. USIP_UH I had 12 successful launches with 9 recoveries from Fairbanks, AK in March 2015, and 4 piggyback flights with BARREL 3 from Esrange, Kiruna, Sweden in August, 2015. USIP_UH II had 8 successful launches with 5 recoveries from Fairbanks, AK in March 2017, 3 piggyback flights with BARREL 4 from Esrange, Kiruna, Sweden in August, 2016, and 1 flight each from CSBF and UH. The great opportunity of this program is capitalizing on the proliferation of electronics miniaturization to create new generations of scientific instruments that are smaller and lighter than ever before. This situation allows experiments to be done more cheaply which ultimately allows many more experiments to be done.

    Nuclear physics research is fundamental to our understanding of the visible universe and at the same time intertwined with our daily life. Nuclear physics studies the origin and structure of the atomic nuclei in terms of their basic constituents, the quarks and gluons. Atoms and molecules would not exist without underlying quark-gluon interactions, which build nearly all the mass of the visible universe from an assembly of massless gluons and nearly-massless quarks. The study of hadron structure with electromagnetic probes through exclusive and semi-inclusive scattering experiments carried out at the 12 GeV Jefferson Laboratory plays an important role in this effort. In particular, planned precision measurements of pion and kaon form factors and longitudinal-transverse separated deep exclusive pion and kaon electroproduction cross sections to the highest momentum transfers achievable play an important role in understanding hadron structure and masses and provide essential constraints for 3D hadron imaging. While a growing fraction of nuclear physics research is carried out at large international laboratories, individual university research groups play critical roles in the success of that research. These include data analysis projects and the development of state-of-the-art instrumentation demanded by increasingly sophisticated experiments. These efforts are empowered by the creativity of university faculty, staff, postdocs, and provide students with unique hands-on experience. As an example, an aerogel Cherenkov detector enabling strangeness physics research in Hall C at Jefferson Lab was constructed at the Catholic University of America with the help of 16 undergraduate and high school students. The ''Conference Experience for Undergraduates'' (CEU) provides a venue for these students who have conducted research in nuclear physics. This presentation will present the experiences of one of the participants in the first years of the CEU, her current research program

    The National Oceanic and Atmospheric Administration's (NOAA) National Weather Service (NWS) provides weather, hydrologic, and climate forecasts and warnings for the protection of life and property and the enhancement of the national economy. The NWS's Meteorological Development Laboratory (MDL) supports this mission by developing meteorological prediction methods. Given this mission, NOAA, NWS, and MDL all have a need to continually recruit talented scientists. One avenue for recruiting such talented scientist is the Student Career Experience Program (SCEP). Through SCEP, MDL offers undergraduate and graduate students majoring in meteorology, computer science, mathematics, oceanography, physics, and statistics the opportunity to alternate full-time paid employment with periods of full-time study. Using SCEP as a recruiting vehicle, MDL has employed students who possess some of the very latest technical skills and knowledge needed to make meaningful contributions to projects within the lab. MDL has recently expanded its use of SCEP and has increased the number of students (sometimes called co- ops) in its program. As a co-op, a student can expect to develop and implement computer based scientific techniques, participate in the development of statistical algorithms, assist in the analysis of meteorological data, and verify forecasts. This presentation will focus on describing recruitment, projects, and the application process related to MDL's SCEP. In addition, this presentation will also briefly explore the career paths of students who successfully completed the program.

    Nursing work often occurs in complex and potentially hazardous settings. Awareness of patient and practice environments is an imperative for nurses in practice. To explore nursing students' situation awareness while engaging in simulated patient deterioration scenarios. The educational process of FIRST(2)ACT was the model for the nurse intervention. Situation awareness was measured quantitatively using the Situation Awareness Global Assessment tool. Four domains were measured: physiological perception (patient parameters), global perception (surroundings), comprehension (interpretation of information), and projection (forecasting outcomes). Clinical laboratories at each of three participating universities. Ninety-seven nursing students from three Australian universities. Between March and July 2012, students participated in three video-recorded simulation events, in which a trained actor played patient roles and groups of three students worked as teams. To measure situation awareness, following the simulation each team leader was taken to a separate room and asked to report on a question set regarding the patient's vital signs, bedside setting and medical diagnosis. Overall, situation awareness was low (41%). Of the four domains, physiological perceptions scored the lowest (26%) and projection the highest (59%). Final year nursing students may not have well developed situation awareness skills, especially when dealing with these types of scenarios. Education providers need to consider ways to assist students to fully develop this attribute. Findings suggest that this is an aspect of undergraduate nursing education that requires significant consideration by curriculum developers. Crown Copyright © 2014. Published by Elsevier Ltd.

    2012-12-01

    URSSA is the Undergraduate Research Student Self-Assessment, an online survey instrument for programs and departments to use in assessing the student outcomes of undergraduate research (UR). URSSA focuses on what students learn from their UR experience, rather than whether they liked it. The online questionnaire includes both multiple-choice and open-ended items that focus on students' gains from undergraduate research. These gains include skills, knowledge, deeper understanding of the intellectual and practical work of science, growth in confidence, changes in identity, and career preparation. Other items probe students' participation in important research-related activities that lead to these gains (e.g. giving presentations, having responsibility for a project). These activities, and the gains themselves, are based in research and thus constitute a core set of items. Using these items as a group helps to align a particular program assessment with research-demonstrated outcomes. Optional items may be used to probe particular features that are augment the research experience (e.g. field trips, career seminars, housing arrangements). The URSSA items are based on extensive, interview-based research and evaluation work on undergraduate research by our group and others. This grounding in research means that URSSA measures what we know to be important about the UR experience The items were tested with students, revised and re-tested. Data from a large pilot sample of over 500 students enabled statistical testing of the items' validity and reliability. Optional items about UR program elements were developed in consultation with UR program developers and leaders. The resulting instrument is flexible. Users begin with a set of core items, then customize their survey with optional items to probe students' experiences of specific program elements. The online instrument is free and easy to use, with numeric results available as raw data, summary statistics, cross-tabs, and

    2007-09-01

    Full Text Available Objectives: To classify nursing students on a socio-demographic basisin order to check whether they are acquainted with the meaning ofthe term burnout syndrome; to check for the presence of the burnoutsyndrome and assess its levels in undergraduate nurses. Methods:A cross-section study was carried out of 102 students at the NursingSchool of the Hospital Israelita Albert Einstein. A questionnaire wasmade up by the authors and applied along with the Maslachs BurnoutInventory (MBI. Results: Ninety-five percent of students were female,aged 18 to 50 years, 86% were single and 51% reported having jobs.Most of the surveyed subjects were not acquainted with the termburnout syndrome. Out of the total of 39 students, 56.9% classified thedisease as being psychological and caused by professional stress. Asfor the mean MBI subscales, it was found that a relatively high mean(28.6% referred a low feeling of professional accomplishment, a low/moderate mean (23.09% were emotionally exhausted and (9.176%felt depersonalized, which intrinsically proves the absence of burnoutsyndrome in the sample. As for burnout dimensions, the findingsshowed that 73.5% are at a low/moderate level of emotional exhaustion;70.53% suffer from a low/moderate level of depersonalization; and 76%reported a high feeling of professional accomplishment. Conclusion:High means were found at the dimensions of reduced professionalaccomplishment, which calls for the need to intervene in the caseof these students so that they may recall their primary initiativeconcerning their professional choice.

    Millard, Julie T.; Pilon, André M.

    2003-04-01

    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."

    2015-01-01

    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.

    2014-12-01

    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.

    Directory of Open Access Journals (Sweden)

    Cindy R. DeLoney-Marino

    2013-08-01

    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.

    To compare learning styles of undergraduate and postgraduate medical students. Observational, comparative study. Department of Medical Education, Army Medical College, NUST, Rawalpindi, Pakistan, during February and March 2012. A total of 170 students were divided into two equal groups of undergraduate students of Army Medical College, and postgraduate students of Armed Forces Post Graduate Medical Institute, Rawalpindi. Learning Style Questionnaire (LSQ) was used to assess and categorize the participants into Honey and Mumford classification of learning styles. The responses of each student ranging from 'very strong,' 'strong', 'moderate', and 'low' preference towards activist, theorist, reflector and pragmatist learning styles were compiled. The two groups were compared using SPSS version 17, using Fisher's exact test and the chi-square test. A p-value of $lt; 0.05 was considered significant. Preferences for all four learning styles were present in both groups. The results reveal an overall statistically significant difference in the 'very strong' preference in learning styles between the two study groups (p=0.002). Among the undergraduate students, 45% had a very strong preference for being an activist, whereas in postgraduate students, 38% had very strong preference for reflector, and 35% for theorist. This was statistically significant for activist, and reflector, and attained a p-value of learning style was pragmatist in both undergraduate and postgraduate students. Diversity of learning styles at undergraduate and postgraduate level of medical education calls for multiplicity of instructional and assessment modalities to match them. The learning styles amongst the undergraduate medical students are different from the postgraduates. The postgraduates commonly have the reflector learning style while the undergraduates are predominantly activists and theorists.

    Hie, Liana; Chang, Jonah J; Garg, Neil K

    2015-03-10

    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.

    Danielson, Kathryn I; Tanner, Kimberly D

    2015-01-01

    Scientific research exploring ocean acidification has grown significantly in past decades. However, little science education research has investigated the extent to which undergraduate science students understand this topic. Of all undergraduate students, one might predict science students to be best able to understand ocean acidification. What conceptions and misconceptions of ocean acidification do these students hold? How does their awareness and knowledge compare across disciplines? Undergraduate biology, chemistry/biochemistry, and environmental studies students, and science faculty for comparison, were assessed on their awareness and understanding. Results revealed low awareness and understanding of ocean acidification among students compared with faculty. Compared with biology or chemistry/biochemistry students, more environmental studies students demonstrated awareness of ocean acidification and identified the key role of carbon dioxide. Novel misconceptions were also identified. These findings raise the question of whether undergraduate science students are prepared to navigate socioenvironmental issues such as ocean acidification. © 2015 K. I. Danielson and K. D. Tanner.

  14. A survey on faculty perspectives on the transition to a biochemistry course-based undergraduate research experience laboratory.

    Science.gov (United States)

    Craig, Paul A

    2017-09-01

    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.

    2016-11-01

    Aim The promotion of a distributed leadership model in health care means there is an expectation that undergraduate training should contribute to the development of nursing students' leadership capabilities. However, there is concern that the nursing degree programme is not sufficiently preparing students. This study explored nursing students' perceptions of leadership before qualifying, and how prepared they felt to take on leadership roles. Method Data were collected from 20 undergraduate nursing students, using a Straussian grounded theory approach, through three focus groups and six semi-structured interviews. Findings These suggest students are disengaged from the learning of leadership, and preparation for leadership in clinical areas is problematic, as students are exposed to flawed role modelling. Conclusion Discrepancies between nurse education and the realities of clinical practice mean that successfully preparing nursing students for leadership roles will be challenging within current provision.

    Sin, Mo-Kyung; Bliquez, Rebecca

    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.

    2007-01-01

    Undergraduate education is undergoing a shift away from the traditional transmission of a fixed body of knowledge to a learning approach where the emphasis is on supporting learners to learn. Central to this change is recognition that undergraduate education programmes should aim to develop independent learners who become effective lifelong learning practitioners. Successful independent learning as an undergraduate student or as a lifelong learner requires the learner to have well developed information literacy skills. An Online Electronic Information Skills (OEIS) intervention was designed to develop the information literacy skills in a cohort of second year undergraduate radiography students. An evaluation focused on learning outcomes was used to provide evidence of development of information literacy within the undergraduate course. The evaluation clearly demonstrated substantial skill development in students' ability to access scholarly information in their discipline area. The reported continued use of database searching by this cohort of students seven months after the OEIS intervention provides evidence that they are continuing to access and use scholarly information, information literacy skills necessary for their future work context

    2015-11-01

    Full Text Available Student debt in the United States has been quickly increasing during the past decade. As to the first quarter of 2014, the student loan debt surpassed credit cards debt and auto loans. Puerto Rico ranks #17 by total debt among the United States and territories. Nonetheless, students in Puerto Rico have an average of $18,000 of student debt, positioning it at the lowest rank by average debt. This paper explores the debt phenomena among Puerto Rican undergraduate students. Specifically, we want to determine if students have debt, and if so, what type and how they spend it. A sample of 194 undergraduate students from a School of Business at a public higher education institution of Puerto Rico was surveyed. Results indicate that 28% of business students have debt. Female students were more susceptible to have debt. Furthermore, top expenses covered by debt are food, education, car expenses, clothing, and entertainment. The results reveal that 90 percent is not receiving counseling about debt management from the financial aid office. From those receiving the financial advising (10 percent, only 2 percent perceive it as useful. These results provide an exploratory look into the debt and its use among Puerto Rican undergraduate students.

    Full Text Available Depressive disorders are the most typical disease affecting many different factors of humanity. University students may be at increased risk of depression owing to the pressure and stress they encounter. Therefore, the purpose of this study is comparing the level of depression among male and female athletes and non-athletes undergraduate student of private university in Esfahan, Iran. The participants in this research are composed of 400 male and female athletes as well as no-athletes Iranian undergraduate students. The Beck depression test (BDI was employed to measure the degree of depression. T-test was used to evaluate the distinction between athletes and non-athletes at P≤0.05. The ANOVA was conducted to examine whether there was a relationship between level of depression among non-athletes and athletes. The result showed that the prevalence rate of depression among non-athlete male undergraduate students is significantly higher than that of athlete male students. The results also presented that level of depression among female students is much more frequent compared to males. This can be due to the fatigue and lack of energy that are more frequent among female in comparison to the male students. Physical activity was negatively related to the level of depression by severity among male and female undergraduate students. However, there is no distinct relationship between physical activity and level of depression according to the age of athlete and nonathlete male and female undergraduate students. This study has essential implications for clinical psychology due to the relationship between physical activity and prevalence of depression.

    As the need for greater global health competency increases for health care professionals in South Korea, educational efforts for nursing students have begun. This study examined the effectiveness of two educational courses for freshmen and sophomores that were designed to improve students' global health competencies. A trend study was conducted for all undergraduate nursing students enrolled in a 4-year undergraduate nursing program in 2013 and 2014. We assessed students' global health competencies (1-knowledge and interests in global health and health equity, 2-global health skills, and 3-learning needs) in 2013 and 2014 and analyzed variance between mean scores by year and by course exposure, using 95% confidence intervals. Students who took both global health courses (sophomores in both years) reported higher global health-related knowledge and interests than did freshmen (p students' global health competencies. Reinforcement of knowledge in later courses may be needed to build on the global competencies. © 2017 Wiley Periodicals, Inc.

    Full Text Available The DOSPERT, developed by Weber, Blais and Betz, can be used to measure risk behaviors in a variety of domains. We investigated the use of this scale in China. The participants were 1144 undergraduate students. After we removed some items that were not homogeneous, a principal component analysis extracted six components that accounted for 44.48% of the variance, a value similar to that obtained in the analysis conducted by Weber et al. Chinese undergraduates scored higher on the investment subscale compared with the results of Weber's study. The analysis of individual differences indicated that there was a significant gender difference in the ethical, investment and health/safety subscales, where males scored significantly higher than females. The type of home location was also significant on the ethical and health/safety subscales, where undergraduates from the countryside scored lower than undergraduates from cities and towns on the ethical subscale, and undergraduates from towns scored higher than those from other two areas on the health/safety subscale. Male undergraduates from towns scored higher than male undergraduates from other areas on the gambling subscale.

    2018-02-01

    Pro-environmental behavior is an individual action as a manifestation of one's responsibility to create a sustainable environment. University students as one of the agent of change can adopt pro-environmental behaviors concept, even through simple things to do on daily activities such as ride a bicycle or walk for short distance, reuse the shopping bags, separate waste, learn about environmental issues etc. Many studies have examined pro-environmental behavior from various approaches. However, the study about university students' pro-environmental behavior is lacking. The aim of this paper is to examine the undergraduate students' pro-environmental behaviors level. We surveyed 364 first year undergraduate students from a state university in Semarang. The survey included six aspects of pro-environmental behavior in daily practice which include energy conservation, mobility and transportation, waste avoidance, recycling, consumerism, and vicarious behaviors toward conservation. Findings of this study showed the level of pro-environmental behavior of first year undergraduate students is medium. Recommendations for undergraduate students and future researchers are discussed.

    Blended learning is a combination of online and face-to-face learning and is increasingly of interest for use in undergraduate medical education. It has been used to teach clinical post-graduate students pharmacology but needs evaluation for its use in teaching pharmacology to undergraduate medical students, which represent a different group of students with different learning needs. An existing BSc-level module on neuropharmacology was redesigned using the Blended Learning Design Tool (BLEnDT), a tool which uses learning domains (psychomotor, cognitive and affective) to classify learning outcomes into those taught best by self-directed learning (online) or by collaborative learning (face-to-face). Two online courses were developed, one on Neurotransmitters and the other on Neurodegenerative Conditions. These were supported with face-to-face tutorials. Undergraduate students' engagement with blended learning was explored by the means of three focus groups, the data from which were analysed thematically. Five major themes emerged from the data 1) Purpose and Acceptability 2) Structure, Focus and Consolidation 3) Preparation and workload 4) Engagement with e-learning component 5) Future Medical Education. Blended learning was acceptable and of interest to undergraduate students learning this subject. They expressed a desire for more blended learning in their courses, but only if it was highly structured, of high quality and supported by tutorials. Students identified that the 'blend' was beneficial rather than purely online learning.

    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.

    2012-01-01

    It has been identified that health science students, and in particular undergraduate nutrition and dietetics (N&D) students, have distinctive learning needs. The purpose of this study was to investigate the learning styles of undergraduate N&D students enrolled at a large Australian university. An awareness of the learning styles of undergraduate N&D students will assist university educators in providing appropriate learning opportunities and developing curricula to equip N&D graduates with the essential skills they need to work effectively in the modern practice environment. The Kolb Learning Style Inventory (K-LSI), Index of Learning Styles (ILS) and Success Types Learning Style Type Indicator (STLSTI) were distributed to 162 students enrolled in a Bachelor of Nutrition and Dietetics program at one metropolitan university. One hundred twenty-nine questionnaires were returned, providing a response rate of 79.6%. The K-LSI showed that students were inclined toward converging (practical) and assimilating (reasoning) learning styles while the ILS identified the students as intuitive (innovative). The STLSTI results indicated an intraverted, sensing, feeling, judging approach to learning. It is recommended N&D educators take into consideration the learning styles of dietetics students when developing curricula and evaluating teaching approaches. Analysis of learning styles can inform the planning, implementation, and assessment of teaching and learning activities to create effective learning environments, appropriate learning opportunities, and a contemporary curriculum for N&D students.

  7. Formative evaluation of traditional instruction and cooperative inquiry projects in undergraduate chemistry laboratory courses

    Panichas, Michael A.

    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

    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.

    2017-06-01

    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.

  10. Attrition of undergraduate nursing students at selected South African universities

    2016-08-01

    Full Text Available Background: The nursing profession forms the backbone of many healthcare systems. It therefore needs a consistent supply of registered nurses to deliver continuous and safe quality healthcare, and to replace the nurses leaving or retiring from the profession. Attrition actively occurs among nursing students in South Africa and threatens the future supply of registered nurses. Aim: The aim of the study was to describe the attrition rate at selected South African universities and the factors influencing undergraduate nursing students to discontinue their nursing studies at these universities. Method: A quantitative descriptive design was followed. Heads of the nursing departments at the selected universities captured data with a specifically designed questionnaire. Thereafter their former nursing students provided information via a structured telephonic interview on the reasons why they discontinued the nursing programme. Results: The study revealed that attrition of undergraduate nursing students for three intake years (2007, 2008 and 2009 at the participating universities was between 39.3% and 58.7%. Academic and financial reasons as well as poor wellness and health were the main causes for attrition. Another factor was failure to cope with the demands of the clinical environment. Conclusion: Attrition might not occur immediately when a nursing student is challenged, as the student might exploit the various types of support offered. Although some nursing students do benefit from the offered support, a large number of nursing students still discontinue the undergraduate nursing programme.

    Palliative care knowledge is being given meager importance in the curriculum of medical and other allied medical sciences. It is vital that all health care practitioners including medical, pharmacy, physiotherapy and nursing are aware and apply the best principles of palliative care. To assess the awareness of palliative care among undergraduate students of medical, nursing, pharmacy and physiotherapy. The study population included total of 200 students. Among 200 students, 50 were from each of the colleges of medicine, nursing, pharmacy and physiotherapy. After obtaining informed consent, questionnaire was given. The questionnaire contained the sociodemographic profile and 35 statements under nine groups, for which the respondents were expected to answer one out of the three options (Yes, No, Don't know). The groups of statements deal with palliative care definition, its philosophy, communication issues, non-pain symptoms, medications use and context of application of palliative care. It was found that less than 20% of nursing students were unaware of palliative care. Among the undergraduates of college of pharmacy, more than 50% had no knowledge of palliative care. More than 80% of physiotherapy, nursing and medical students agree that death should occur without any pain or symptoms. The need of palliative care was well understood by more than 70% of students of physiotherapy, pharmacy, nursing and medical colleges. Basic knowledge about palliative care was inadequate among the undergraduate students related to healthcare.

  1. The python project: a unique model for extending research opportunities to undergraduate students.

    Science.gov (United States)

    Harvey, Pamela A; Wall, Christopher; Luckey, Stephen W; Langer, Stephen; Leinwand, Leslie A

    2014-01-01

    Undergraduate science education curricula are traditionally composed of didactic instruction with a small number of laboratory courses that provide introductory training in research techniques. Research on learning methodologies suggests this model is relatively ineffective, whereas participation in independent research projects promotes enhanced knowledge acquisition and improves retention of students in science. However, availability of faculty mentors and limited departmental budgets prevent the majority of students from participating in research. A need therefore exists for this important component in undergraduate education in both small and large university settings. A course was designed to provide students with the opportunity to engage in a research project in a classroom setting. Importantly, the course collaborates with a sponsor's laboratory, producing a symbiotic relationship between the classroom and the laboratory and an evolving course curriculum. Students conduct a novel gene expression study, with their collective data being relevant to the ongoing research project in the sponsor's lab. The success of this course was assessed based on the quality of the data produced by the students, student perception data, student learning gains, and on whether the course promoted interest in and preparation for careers in science. In this paper, we describe the strategies and outcomes of this course, which represents a model for efficiently providing research opportunities to undergraduates. © 2014 P. A. Harvey et al.

  2. Structured inquiry-based learning: Drosophila GAL4 enhancer trap characterization in an undergraduate laboratory course.

    Directory of Open Access Journals (Sweden)

    Christopher R Dunne

    2014-12-01

    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.

    Chism, Grady W.; Vaughan, Martin A.; Muralidharan, Pooja; Marrs, Jim A.

    2016-01-01

    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.

    2010-09-01

    Depression is a serious and often under-diagnosed and undertreated mental health problem in college students which may have fatal consequences. Little is known about ethnic differences in prevalence of depression in US college campuses. This study compares depression severity in Asian-American and Caucasian undergraduate students at the University of California San Diego (UCSD). Participants completed the nine item Patient Health Questionnaire and key demographic information via an anonymous online questionnaire. Compared to Caucasians, Asian-Americans exhibited significantly elevated levels of depression. Furthermore, Korean-American students were significantly more depressed than Chinese-American, other minority Asian-American, and Caucasian students. In general, females were significantly more depressed than males. Results were upheld when level of acculturation was considered. The demographic breakdown of the student population at UCSD is not representative to that of the nation. These findings suggest that outreach to female and Asian-American undergraduate students is important and attention to Korean-American undergraduates may be especially worthwhile. 2010 Elsevier B.V.

    The purpose of this study was to compare the incidence of grief among American and Arab female undergraduate students, the effects of their grief, and risk of prolonged grief disorder. A total of 471 female undergraduate students, 308 (65.4%) from the United Arab Emirates and 163 (34.6%) from the United States, completed a survey about their grief experiences. Students experiencing a significant loss also completed the Prolonged Grief Disorder Questionnaire. Findings revealed that overall approximately 38.4% (n = 181) of all 471 students experienced the loss of a significant person in their lives within the past 24 months; a similar percentage was found in each sub group. Students reported various grief effects with American students experiencing more effects related to sleep, relationships, academics, physical well-being, religion/spirituality, and outlook on life than Arab students. Only a small number (10, 5.52%) of students met the criteria for prolonged grief disorder; however, most students were female Arab students. Limitations of the study and recommendations for future research are provided.

    2017-02-01

    The Great Recession's influence on American undergraduate students' values was examined, testing Greenfield's and Kasser's theories concerning value development during economic downturns. Study 1 utilised aggregate-level data to investigate (a) population-level value changes between the pre-recession (2004-2006: n = 824,603) and recession freshman cohort (2008-2010: n = 662,262) and (b) overall associations of population-level values with national economic climates over long-term periods by correlating unemployment rates and concurrent aggregate-level values across 1966-2015 (n = 10 million). Study 2 examined individual-level longitudinal value development from freshman to senior year, and whether the developmental trajectories differed between those who completed undergraduate education before the Great Recession (freshmen in 2002, n = 12,792) versus those who encountered the Great Recession during undergraduate years (freshmen in 2006, n = 13,358). Results suggest American undergraduate students' increased communitarianism (supporting Greenfield) and materialism (supporting Kasser) during the Great Recession. The recession also appears to have slowed university students' development of positive self-views. Results contribute to the limited literature on the Great Recession's influence on young people's values. They also offer theoretical and practical implications, as values of this privileged group of young adults are important shapers of societal values, decisions, and policies. © 2016 International Union of Psychological Science.

    This study aimed to assess the level of knowledge, attitudes, and practices regarding infection control procedures among undergraduate dental students. This was a questionnaire-based cross-sectional survey. A self-administered questionnaire consisting of questions on students' vaccination status as well as knowledge and attitudes regarding infection control was sent to 600 undergraduate dental students in the fourth, fifth, and sixth year of the Al-Farabi College for Dentistry and Nursing, Riyadh, Saudi Arabia. The collected data were analyzed using SPSS software. The significance level was set at P<0.05. The response rate was 85% (512 out of 600). While the vast majority of students (90%) had been vaccinated against hepatitis, only 37.4% have been assessed for anti-HBs. A total of 98.8% and 90.8% reported always wearing gloves and masks, respectively, during dental procedures. The use of protective eyewear was reported by only 29.2%. A significantly higher proportion of sixth-year students showed a positive attitude toward the treatment of patients with infectious diseases than other students of lower academic years. Approximately one-third of students reported having one or more occupational injuries while treating their patients. Although the students had good knowledge and attitudes regarding infection control, the compliance and practice levels regarding the same were low. Such findings highlight the necessity of continued infection-control education of Saudi dental students.

    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.

    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.

  19. Gamification of the Laboratory Experience to Encourage Student Engagement

    Full Text Available The American Society for Microbiology (ASM Task Force on Curriculum Guidelines for Undergraduate Microbiology Students published recommendations for introductory microbiology courses that suggest teaching specific skill sets in the laboratory beyond just fundamental knowledge and concepts of microbiology (6; however, students can sometimes view a skills-based laboratory experience as a task list of unrelated assignments to complete for a grade. Therefore, providing explicit connections throughout the lecture and laboratory exercises is critical for a truly integrated learning experience. Several pedagogical techniques can provide a coherent framework throughout a course. For example, case-based studies can connect lecture with laboratory skills and increase student engagement by applying newly developed knowledge and skills to tackle real-world simulations (2, 3. One reason that case-based studies succeed is that they can provide intrinsic motivations and an alternate purpose for students to engage with the material. A more recent trend in pedagogy involves using game design elements to increase student engagement and motivation. Gamification is the application of game design (accruing points or badges, reaching significant levels of accomplishment, or other reward elements in a non-game context to motivate or influence participation (1, 5. A natural extension of both of these methods is to gamify a case-based approach where a fictional scenario is presented for students to role-play as scientists using their developed skills to solve a complex problem. The typical microbiology laboratory, as described by the ASM Task Force, can easily incorporate game design elements without extensive modification of the exercises themselves. Instead, gamification involves structuring the lab in a way that gives the course a coherent and unified purpose. This ultimately allows the student to see how the principles and concepts of lecture and laboratory connect

    Controlled, fully solar-powered flight in a rotorcraft is a difficult engineering challenge. Over the past five years, multidiciplinary teams of undergraduate engineering students at the National University of Singapore have built and test-flown a succession of increasingly impressive and larger, more efficient aircraft. While many other multidisciplinary or purely photonics projects are available to students in our programme, this particular project attracts an unusual level of excitement and devotion among students working on it. Why is that the case, and what, in general, makes a good final year undergraduate design project? These questions will be explored. Additionally, videos of solar helicopter test flights and spectacular crashes will be shown in the presentation for which the proceedings below have been prepared.

    2012-11-01

    This article reports research findings from a survey of 261 students regarding their perceptions of psychiatrists. Overall, students view psychiatrists as competent and prestigious. At the same time, however, only approximately half of respondents reported having a "positive view" of these professionals and around one-third were neutral. College students view psychiatrists as effective for treating relatively severe mental health problems, although depression was not considered to be a psychiatrist's relative strong suit (only half viewed them as being effective). Some confusion between psychiatrists and psychologists seemed apparent. Although students did not consider the media a highly reliable source of information, media sources nonetheless appeared to play a dominant role in determining how college students framed psychiatry roles. We discuss the results in the context of the need for further education by the specialty of psychiatry and the importance of reversing what appears to be some negative stereotyping.

  15. Developing a new experimental system for an undergraduate laboratory exercise to teach theories of visuomotor learning.

    Kasuga, Shoko; Ushiba, Junichi

    2014-01-01

    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.

  16. Social Networks in the Information Horizons of Undergraduate Students

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available The information horizon is a mental map where users position their information sources in different contexts and situations, and the social network is one of the critical concepts in information horizons. Previous research on undergraduate and graduate students’ information horizons has revealed that various human sources are used in academic or career-related contexts (Sonnenwald, Wildemuth. & Harmon, 2001; Tsai, 2010. While most literature shows that stronger tie sources are more likely to be used as a preferred or primary information source (Steffes & Burgee, 2009, Granovetter (1973 emphasizes the importance of “the strength of weak ties” in information diffusion. This study aims to examine undergraduates’ social networks in their coursework-related information horizons as well as to investigate how strong and weak ties are positioned in their information horizons. A pretest of a web survey with 18 responses and 3 brief follow-up interviews were conducted with an undergraduate class at a large state university. After the pretest, fifteen undergraduate students were recruited to participate in the study. Results showed that undergraduate students tend to rely more on their colleagues and teaching assistants than on professors when they have questions on coursework-related issues. While stronger ties may be more frequently consulted for moral support, the tie strength does not necessarily determine the frequency of consultation about other coursework-related issues.

    An Undergraduate Nurse Employment Demonstration Project (UNDP) was implemented in four Health Service Areas in British Columbia with a concurrent evaluation study. This demonstration project comprised the development and implementation of a new position in the BC healthcare system. The position enabled third- and fourth-year nursing students to be employed at their level of education. The purposes of the evaluation were to explore the feasibility and outcomes of this type of paid undergraduate student nurse employment. The three-year project and evaluation included both implementation and outcome analysis. The implementation evaluation design was descriptive and prospective, involving multiple data sources. The outcome evaluation design was quasi-experimental, with intervention and comparison groups. Learning outcomes for undergraduate nurses were increased confidence, organizational ability, competency and ability to work with a team. Workplace outcomes were increased unit morale, help with workload and improved patient care. New graduates with undergraduate nurse experience reported less time required for orientation and transition than other graduates who did not have this experience, and workplace nurses viewed these new graduates as more job-ready than other new graduates. After 21 months, new graduates with undergraduate nurse experience were less likely to move to other employment than other new graduates. Results from the four Health Service Areas indicated that the paid undergraduate nurse position was feasible and that outcomes benefited students, new graduates and workplaces. The undergraduate nurse position is now being implemented throughout all Health Service Areas in British Columbia.By 2000, concerns in British Columbia about the nursing workforce, workplace and patient safety had escalated to the point where diverse stakeholder groups were prepared to work together in new ways to prepare nursing graduates to be more job-ready, to recruit and retain

    2011-12-01

    We are assembling a group of web-based educational modules for a course entitled "Introduction to Mineral Physics". Although the modules are designed to function as part of a full semester course, each module will also be able to stand alone. The modules are targeted at entry level graduate students and advanced undergraduate students. Learning outcomes for the course are being developed in consultation with educators throughout the mineral physics community. Potential users include mineral physicists teaching "bricks and mortar" graduate classes at their own institutions, mineral physicists teaching graduate classes in a distance education setting, mineralogy teachers interested in including supplementary material in their undergraduate mineralogy class, undergraduates doing independent study projects and graduate students and colleagues in other subdisciplines who wish to brush up on mineral physics topics. The modules reside on the Science Education Resource Center at Carleton College web site in the On the Cutting Edge - Teaching Mineralogy collection. Links to the materials will be posted on the Consortium for Materials Properties Research in Earth Sciences website. The modules will be piloted in a graduate level distance education course in mineral physics taught from UNLV during the spring 2012 semester. This course and others like it can address the current problems faced by faculty in state universities where rising minimum enrollments are making it difficult to teach a suitable graduate course to incoming students.

    2009-06-01

    Films featuring psychiatrists, psychiatry and the mentally ill abound, for better or for worse. The use of cinema in postgraduate psychiatry training has been gaining increasing acceptability, but its potential for use in undergraduate psychiatry has received little attention in the literature. This paper reports on the rationale behind, and medical students' responses to a special study module for third year medical students at King's College London, which utilized movies to highlight the significance of the social, cultural and historical context in shaping representations of mental illness, psychiatry, and psychiatrists. Medical students were very receptive to the use of film as an educational tool and able to understand both the benefits and limitations. They found the module enjoyable, and subjectively rated their knowledge of psychiatric topics and the history of psychiatry as significantly improved. The results presented are course feedback from medical students (n = 8) who completed the module. Although our findings provide provisional support for the use of film as an educational tool in undergraduate psychiatry, more systematic research is needed to delineate the potential role of cinema in undergraduate psychiatric education.

    2011-07-01

    A review of the nursing literature reveals many undergraduate nursing students lack proficiency with basic mathematical skills, those necessary for safe medication preparation and administration. Few studies exploring the phenomenon from the undergraduate nursing student perspective are reported in the nursing literature. The purpose of this study was to explore undergraduate nursing students’ perceptions of math abilities, factors that affect math abilities, the use of math in nursing, and the extent to which specific math skills were addressed throughout a nursing curriculum. Polya’s Model for Problem Solving and the Bloom’s Taxonomy of Educational Objectives, Affective Domain served as the theoretical background for the study. Qualitative and quantitative methods were utilized to obtain data from a purposive sample of undergraduate nursing students from a private university in western Pennsylvania. Participants were selected based on the proficiency level with math skills, as determined by a score on the Elsevier’s HESI™ Admission Assessment (A2) Exam, Math Portion. Ten students from the “Excellent” benchmark group and eleven students from the “Needing Additional Assistance or Improvement” benchmark group participated in one-on-one, semi-structured interviews, and completed a 25-item, 4-point Likert scale survey that rated confidence levels with specific math skills and the extent to which these skills were perceived to be addressed in the nursing curriculum. Responses from the two benchmark groups were compared and contrasted. Eight themes emerged from the qualitative data. Findings related to mathematical approach and confidence levels with specific math skills were determined to be statistically significant.

  2. Towards the Development of Phospholipid-Encapsulated Gold Nanorod Chains for Enhanced Raman-Scattering and the Improvement of Student Scientific Communication Skills in Undergraduate Classroom and Laboratory Settings

    Science.gov (United States)

    Stewart, Alexander F.

    Depending on functionalization, nanospecies can serve effectively as Surface Enhanced Raman Scattering (SERS) probes. Their efficacy can be improved by tuning their shape and concentrating their electric field profile into smaller regions. This tuning is seen particularly well in nanorods, which concentrate such fields near the rod tips or ends, in 'hotspots'. These hotspots can be constructively enhanced through the self-assembly of the nanospecies in question, further increasing the enhancement of Raman-active species within. When considering their potential application as SERS probes, both the separation of end-to-end assembled nanorods (gap size), as well as the degree of assembly (chain length), are factors that must be optimized to obtain maximal signal. This thesis reports on the development of robust and variable methods for assembling gold nanorod species in an end-to-end configuration, and for investigating their effectiveness as SERS probes. Using both polymers and short charged ligands with control over their locations of attachment to gold nanorods, nanorod assembly could be initiated in a longitudinal direction either through changing the solvent system or through the introduction of bridging ligands. Exploitation of the inter-rod gap 'hotspot' region allowed for significant Raman enhancement of species located in said gap. Using phospholipids to encapsulate the assembling nanorod allowed for significant control over the proportions of species, in terms of length of the nanorod chain. This control allowed for further optimization of the Raman signals from species of interest. This thesis also details the investigation, over a period of several academic years, of the success of the Writing Instruction and Training (WIT) program, an initiative to iteratively improve student written communication skills as they related to scientific chemical communication. In courses ranging from first to third year, undergraduates were provided with opportunities to

    Despite the fact that environmental consequences derived from food waste have been widely known, studies on the amount of food waste and its influencing factors have relatively been paid little attention. Addressing this shortage, this paper aimed to quantify monthly avoidable food waste generated by Indonesian undergraduate students and analyse factors influencing the occurrence of avoidable food waste. Based on data from 106 undergraduate students, descriptive statistics and logistic regression were applied in this study. The results indicated that 4,987.5 g of food waste was generated in a month (equal to 59,850 g yearly); or 47.05 g per person monthly (equal to 564.62 g per person per a year). Meanwhile, eating out frequency and gender were found to be significant predictors of food waste occurrence.

    Hubenthal, Michael; Boyd, Tom; Lahr, John; Taber, John

    Using seismometers as a catalyst for learning, the IRIS Consortium has partnered with the Colorado School of Mines (CSM) and the U.S. Geological Survey (USGS) to intensively expose the 2002 CSM freshman engineering class to geophysics instrument design. These students worked to design inexpensive seismic recording systems for use in educational environments as part of the Engineering Practices Introductory Course Sequence (EPICS).Through the EPICS courses, CSM strives to strengthen the ability of first-year engineering students to resolve open-ended problems in a team environment and learn skills that are vital to their success as engineers. Students learn AutoCAD, technical drawing/drafting skills, prototyping, analysis skills, and communication skills necessary to present and promote engineering design solutions to the professional community. These engineering skills, introduced through coursework, are applied to an open-ended engineering challenge throughout the semester. Although the CSM faculty clearly has skills and expertise in engineering, as well as the pedagogy to deliver this information, the program needs exciting, real-world engineering challenges, technical support to develop the problem, and the human resources and experience to provide students with sufficient content knowledge to attempt the challenge.

    2016-06-01

    Sexually transmitted diseases (STDs) are the main global cause of acute illness and death and represent a high socioeconomic cost. Undergraduate students are highly exposed to STDs. The research developed at UNICAMP sought to quantify and generate self-perception of knowledge(or lack thereof) about STDs, as well as evaluate the interest of the students in a course on the topic. The data collection instrument was a questionnaire sent electronically to students about to graduate at the end of 2011 and to freshmen in 2012. The questionnaire was answered by 1,448 seniors and 371 freshmen. Twenty percent of seniors and 38% of freshmen had no sexual activity. Among sexually active students, 26.9% had no regular partner and 28.2% more than two partners per year. The condom was used by 99% of students, but less than 20% used them appropriately. About 80% were unaware that condoms do not provide protection outside the barrier area; they intended to read more about STDs and learnt something about the subject. Nearly half of the students considered that a course should be offered to all undergraduates. These findings will be of use in defining strategies for prevention and the teaching tool could be used in other learning environments.

    Perpetual students are problematic, both for campus and for themselves. Inefficient student management could lead to bad lecturer: students’ ratio and cause complicated problem for students and parents. This paper describes ICT used by an Informatics department of a big private university in Indonesia to help 203 perpetual undergraduate students finishing their study in a short time. Lengths of study are varying from 7 until 15 years and most of them suffered from some compulsory credits and mandatory internship project. We observed wide-range of ICT used for data management and communication during the beginning, middle and the end of periods. Success rate of finding perpetual students and producing graduates are almost 70%, but this percentage could be higher if we maximize ICT use. Information sharing type, social media, privacy and patience become important issues related with the use of ICT.

    Analyzing students' performance and self-criticism of their roles in promoting health literacy can inform nursing education in a social environment that expects new graduates to be health promoters. The pilot study reported here aimed to a) analyze students' understanding of and sensitivity to issues of health literacy, (b) identify students' perceptions of structural, organizational, and political barriers to the promotion of health literacy in social and health care organizations, and (c) document students' suggestions for curriculum changes that would develop their skills and competencies as health-literacy promoters. A qualitative pilot study. A collaborative undergraduate nursing degree program in the metropolitan area of Toronto, Canada. Sixteen undergraduate, Year 4 nursing students. Signed informed consent was obtained from the participants. Participation was unpaid and voluntary. Recruitment was through an email invitation sent by the School of Nursing Student Affairs Coordinator. Three, one-time individual interviews and three focus groups were conducted. All were audio-recorded. Recordings were transcribed, and the transcriptions were coded using the qualitative software ATLAS ti 6.0. The interview data were submitted to thematic analysis. Additional data were gathered from the two-page self-assessments in students' academic portfolios. Sensitivity to health literacy was documented. Students performed best as health promoters in supportive teaching hospitals. Their performance was hindered by clinical settings unsupportive of health education, absence of role models, and insufficient theoretical preparation for health teaching. Students' sensitivity to their clients' diversity reportedly reinforced the interconnection, in multicultural healthcare settings, between health literacy and other social determinants of health and a growing demand for educating future nurses in expanding their role also as health promoters. Students recommended more socially

    Shoop, Barry L.

    2014-07-01

    A desirable goal of engineering education is to teach students how to be creative and innovative. However, the speed of technological innovation and the continual expansion of disciplinary knowledge leave little time in the curriculum for students to formally study innovation. At West Point we have developed a novel upper-division undergraduate course that develops the critical thinking, creativity and innovation of undergraduate science and engineering students. This course is structured as a deliberate interactive engagement between students and faculty that employs the Socratic method to develop an understanding of disruptive and innovative technologies and a historical context of how social, cultural, and religious factors impact the acceptance or rejection of technological innovation. The course begins by developing the background understanding of what disruptive technology is and a historical context about successes and failures of social, cultural, and religious acceptance of technological innovation. To develop this framework, students read The Innovator's Dilemma by Clayton M. Christensen, The Structure of Scientific Revolutions by Thomas S. Kuhn, The Discoverers by Daniel J. Boorstin, and The Two Cultures by C.P. Snow. For each class meeting, students survey current scientific and technical literature and come prepared to discuss current events related to technological innovation. Each student researches potential disruptive technologies and prepares a compelling argument of why the specific technologies are disruptive so they can defend their choice and rationale. During course meetings students discuss the readings and specific technologies found during their independent research. As part of this research, each student has the opportunity to interview forward thinking technology leaders in their respective fields of interest. In this paper we will describe the course and highlight the results from teaching this course over the past five years.

    The Objective Structured Clinical Examination (OSCE) has been considered a modern type of examination for the assessment of clinical skills within nurse education, but it has been rarely applied in the teaching of midwifery. The aim of the present study was to assess the use of the OSCE as a tool to evaluate the abilities of undergraduate midwifery students and to compare the perspectives of the students regarding the OSCE and traditional examination. Fifty-two midwifery students participated in the study. The export trainer evaluated the internal consistency of the OSCE stations and it was tested by using Cronbach’s alpha. Successive groups of students completed a self-administered questionnaire immediately after the final examination. The students’ perspective regarding the traditional final examination ranked as unsatisfactory by more than two thirds of the students, while, the students’ perspective regarding the OSCE system was ranked as very satisfactory to satisfactory by more than half of the students (p=0.001). There was a significant difference in the students’ perspective between the OSCE system and the traditional final examination among the students (49.8±18.3 vs 25.3±18.1) (p=0.001). A significant difference was found in being credible (p=0.0001), consistent/reliable (p=0.001), enhances teaching level (p=0.011), and measures the course category (p=0.008) between two methods of the final examination. Around half of the students expressed their opinion that the OSCE test was a stressful assessment. Overall, students’ evaluation of the OSCE was remarkably encouraging. To this end, we recommend the consideration of the validity and reliability of the process for undergraduate midwifery students. PMID:23599825

    Assessment is perceived to create highly stressful environment among medical students. Several studies have reported exam-related anxiety symptoms but the contributing factors seem to differ across institutions. This study aimed to determine the prevalence of exam anxiety, gender differences and the variables that moderate exam anxiety among students of a Saudi medical school. A cross-section study was done on 5th year medical students by administering a 12-statement self-administered questionnaire. The degree of exam anxiety was gauged by a visual analog scale. Of 125 students, 111 responded (response rate 89%). About 65% students experienced exam anxiety due to various reasons. Studying all night before exam (28 students; 25.2%) and extensive course load (26 students; 23.4%) were the major confounding factors. Female students experienced more stress due to extensive course load as compared with male students (p = .00). The data about the identified risk factors for exam anxiety can help medical educators to deeply understand the reasons for exam anxiety. There is a need to reassess the amount of study material in undergraduate medical curricula and students need to organize their time management skills to cope with exam anxiety.

    1999-11-01

    Clinical teaching is a dynamic process that occurs in a variety of sociocultural contexts. The quality of student-teacher interaction in the clinical field can either facilitate or hinder the students' learning in the clinical area. This paper presents the results of a study to explore Jordanian undergraduate nursing students' perceptions of effective clinical teacher characteristics. The results showed that overall, the nursing students rated the professional competence of the clinical teacher as the most important characteristic, which when compared to the Western population was different. When male and female nursing students' perceptions were compared, no significant differences were found. However, responses of nursing students from the three academic years differed significantly in that second-year students rated the clinical teachers' relationship with students as most important and fourth-year students rated personal qualities of the clinical teachers as most important. The results were significant in that they were congruent with the students' level of education and most importantly, their cultural beliefs and values about education.

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.

    Full Text Available Background and Objective: The rubber dam is used in dentistry to create saliva-free working environment during operative procedures. Despite its numerous advantages, utilization is poor in dental schools. We sought to determine undergraduate dental students' perception, educational satisfaction, and attitude regarding the use of rubber dam. Materials and Methods: This cross-sectional survey was carried out among 5th and 6th year undergraduate dental students. A structured questionnaire was developed that sought their perception, educational satisfaction, and attitude regarding the use of rubber dam. Data collected were analyzed using IBM SPSS version 21.0. P <0.05 was considered statistically significant. Results: One hundred and nine students participated in the study; 66 (60.6% females and 43 (39.4% males with a mean age of 23.4 ± 2.02. Most of the students, i.e., 73 (67% were satisfied with their classroom experience with regard to the use of rubber dam but were least satisfied with their laboratory and clinical training. There was a statistically significant association between the students' satisfaction with their training in the use of rubber dam and the confidence to use the rubber dam on their patients (P = 0.001. Conclusion: The students agreed to the importance of rubber dam but were not satisfied with their hands-on clinical training. The use of rubber dam postgraduation may be influenced by the dental educator's method of training, motivation, and consistency in its use. Students who acquire competence and are confident in the use of rubber dam during their undergraduate training are more likely to continue to use the skills following graduation.

    With the development of science and technology, all teachers in the college will face how to stimulate the undergraduate student's ability and make them to be an excellent engineer. For solving these questions, a new scheme with three steps has been designed. First, students will participate in the class teaching activity not only teacher. It will encourage them to read many extracurricular books and articles. Second, they will be required to think and design more new experiments after complete all experiment about the textbook and join more competition of the innovation and entrepreneurship. Third, some students who have more time and ability can early enter into his advisor professor's lab to join various science and technology project. By this scheme, it will be realized to improve student's innovation ability and be a brilliant engineer.

    Objectives To compare longitudinal data with previous cross-sectional data regarding Australian undergraduate pharmacy students' approaches to learning, and explore the differences in approaches to learning between undergraduate and postgraduate cohorts. Methods Longitudinal, repeated measures design using a validated self-report survey instrument were used to gather data. Results Undergraduate students' preferences for meaning directed, undirected, and reproduction-directed approaches to learning displayed the same pattern across the 2 studies; however, application-directed scores increased significantly in the second half of the undergraduate degree program. Commencing postgraduate students' approaches to learning were similar to finishing undergraduate students, and this group was significantly more oriented towards meaning-directed learning compared to undergraduate students. Conclusions Pharmacy students' maturation in approach to their learning was evident and this bodes well for pharmacists' engaging in life-long learning and capacity to work in increasingly complex health settings.

    2017-01-01

    Full Text Available Background: Spirituality is considered one of the determinants of health. Various studies have documented its role in the management of psychological illnesses such as schizophrenia, and anxiety disorders. Doctors often lack skills to do spiritual assessment of the patients. Aim: The current study was conducted among the 1st year undergraduate medical students to find out their ideas and thoughts about spirituality using self-administered questionnaire. Methodology: This was a college based cross sectional study wherein 168 students were interviewed using semistructured, self administered questionnaire. Ethical clearance was obtained from Institutional ethical committee.Results: Most of the students (93.5% believed in spirituality, but only about half (49% of them had complete knowledge about it. Only psychological disorders and chronic diseases were labeled by students who need spirituality as a modality of treatment. Girls linked spirituality with God more than boys. A formal training in spirituality is not essential according to 43% of the subjects. Conclusion: The undergraduates need to understand the importance of this dimension of health. A mere gain in knowledge about spiritual strength available in some of the textbooks would not be able to orient doctors sufficiently to apply it in their practice. Future Direction: Skill building and practicing the culture of spiritual counseling among health workers is the need of hour.

    Full Text Available Equal access to education is a growing concern throughout the nation. With an increasing amount of programs aimed to support the underrepresented populations on college campuses, first generation college students have grown to be a target population of particular interest. This study examined the relationships between first generation college seniors and applications to graduate or professional programs. The goal of this study was to determine if first generation students are pursuing advanced degrees at lower rates than non-first generation students and if so, attempt to uncover factors contributing to that evidence. Data were gathered from the National Longitudinal Survey of Freshman data set, and variables were analyzed using a binary logistic regression. The results of the study indicate that first generation students are significantly less likely to pursue an advanced degree, even when controlling for race, gender, family income, and cumulative grade point average, suggesting a distinctive impact of first generation status on post-undergraduate aspirations. However, after controlling for the impact of self-reported undergraduate loans, the effect of first generation status was no longer significant. The findings in this study provide an important new perspective in the field of sociology.

  7. Undergraduate engineering students' experiences of interdisciplinary learning: a phenomenographic perspective

    Science.gov (United States)

    Hsu, Ming-Chien

    Engineers are expected to work with people with different disciplinary knowledge to solve real-world problems that are inherently complex, which is one of the reasons that interdisciplinary learning has become a common pedagogical practice in engineering education. However, empirical evidence on the impact of interdisciplinary learning on undergraduates is lacking. Regardless of the differences in the scope of methods used to assess interdisciplinary learning, frameworks of interdisciplinary learning are imperative for developing attainable outcomes as well as interpreting assessment data. Existing models of interdisciplinary learning have been either conceptual or based on research faculty members' experiences rather than empirical data. The study addressed the gap by exploring the different ways that undergraduate engineering students experience interdisciplinary learning. A phenomenographic methodological framework was used to guide the design, data collection, and data analysis of the study. Twenty-two undergraduate engineering students with various interdisciplinary learning experiences were interviewed using semi-structured protocols. They concretely described their experiences and reflected meaning associated with those experiences. Analysis of the data revealed eight qualitatively different ways that students experience interdisciplinary learning, which include: interdisciplinary learning as (A) no awareness of differences, (B) control and assertion, (C) coping with differences, (D) navigating creative differences, (E) learning from differences, (F) bridging differences, (G) expanding intellectual boundaries, and (H) commitment to holistic perspectives. Categories D through H represent a hierarchical structure of increasingly comprehensive way of experiencing interdisciplinary learning. Further analysis uncovered two themes that varied throughout the categories: (i) engagement with differences and (ii) purpose and integration. Students whose experiences lie

    Development of engineer's “Human Performance” is being required to respond to various changes. “Human Performace” is defined as an ability of putting own knowledge and skill to a practical issue. Current engineering undergraduate education promotes to learn this ability. To examine effectiveness of the educational program, a questionnaire consisting of 66 items was developed and the survey was conducted across eight universities. As results, most students recognize importance of the ability, but their achievement is lower for English communication skill and adaptation of cultural difference. They learned the ability on laboratory experience for their thesis, experiment class, club activities, part-time jobs and other activities.

    Life science professional societies play important roles for undergraduates in their fields and increasingly offer membership, fellowships, and awards for undergraduate students. However, the overall impacts of society-student interactions have not been well studied. Here, we sought to develop and test a pilot survey of undergraduate students to determine how they got involved in research and in presenting at the Experimental Biology (EB) meeting, what they gained from the scientific and career development sessions at the meeting, and how the American Physiological Society (APS) can best support and engage undergraduate students. This survey was administered in 2014 and 2015 to undergraduate students who submitted physiology abstracts for and attended EB. More than 150 students responded (38% response rate). Respondents were demographically representative of undergraduate students majoring in life sciences in the United States. Most students (72%) became involved in research through a summer research program or college course. They attended a variety of EB sessions, including poster sessions and symposia, and found them useful. Undergraduate students interacted with established researchers at multiple venues. Students recommended that APS provide more research fellowships (25%) and keep in touch with students via both e-mail (46%) and social media (37%). Our results indicate that APS' EB undergraduate activities are valued by students and are effective in helping them have a positive scientific meeting experience. These results also guided the development of a more streamlined survey for use in future years. Copyright © 2017 the American Physiological Society.

This cross-sectional study was conducted in II MBBS (Group A), III MBBS Part I (Group B), and III MBBS Part II (Group C) students. Prevalidated questionnaire about knowledge, attitude, and practice of self-medication were administered to participants. Data were analyzed using one-way analysis of variance and Chi-square test. Out of 582 students who responded to questionnaire, 518 suffered from acne. Self-medication practice was observed in 59.2% students. Significantly higher number of female students practiced self-medication ( P self-medication. A total mean score of knowledge was significantly higher in Group C as compared to Group A ( P medication was preferred by 69.8% students. Seventy-five percentage students read leaflet/package insert/label instruction and expiry date of the medicines. The participating students lack the knowledge about self-medication for acne. Adequate knowledge and awareness about the appropriate use of medication will reduce the practice of self-medication and improve rational prescribing.

    Cardiovascular disease is the number one cause of death worldwide. However, there is not enough data exploring student nurses' understanding, knowledge, and awareness of cardiovascular disease. To investigate knowledge of cardiovascular disease and its risk factors among undergraduate nursing students, with an emphasis on understanding of cardiovascular disease as the primary cause of mortality and morbidity, both in Turkey and worldwide. This cross-sectional survey assessed 1138 nursing students enrolled in nursing schools in Istanbul, Turkey. Data were collected using the Cardiovascular Disease Risk Factors Knowledge Level (CARRF-KL) scale and questions from the Individual Characteristics Form about students' gender, age, level of education, and family cardiovascular health history, as well as smoking and exercise habits. Respondents demonstrated a high level of knowledge about cardiovascular disease, with years of education (p students were not aware that cardiovascular disease is the primary cause of mortality and morbidity in Turkey and worldwide. The majority of the respondents' body mass index (87%) and waist circumference values (females: 90.3%, males: 94.7%) were in the normal range and most were non-smokers (83.7%). However, more than half of the students did not exercise regularly and had inadequate dietary habits. Although students were knowledgeable about cardiovascular disease and associated risk factors, there were significant gaps in their knowledge; these should be addressed through improved nursing curricula. While students were generally healthy, they could improve their practice of health-promoting behaviors. © The European Society of Cardiology 2014.

    The purpose of this research was to explore different aspects of the link between alcohol use and gambling among undergraduate university students (N = 121). Potential aspects of the link examined included level of involvement in each behavior, consequences, motives for involvement, and impaired control over involvement. Results confirmed that drinking and gambling among university students are associated, consistent with the expectations of a problem syndrome model. The strongest link was between general dimensions of problematic involvement for both behaviors. Students who drink to cope and have other indicators of alcohol problems are more likely to gamble to cope, gamble to win money, and have higher gambling involvement and gambling-related problems. However, the salience of drinking and gambling to cope in this relationship is an interesting finding that needs further exploration and extension to other problem behaviors.

    Full Text Available The purpose of the study was to know the definitions nursing students have concerning the death-dying process. A descriptive-qualitative study developed in 2010, with 65 students of the first and last year of Nursing in a public university. Data was collected through semi-structured interview and submitted to content analysis. Data showed that the students possess diverse opinions concerning this process, per times seeing it as natural however difficult to be understood and accepted, especially because it brings pain, suffering, losses and family unstableness. They also revealed that they do not feel prepared to experience terminality in their future customers. The results reinforce the importance of having the thematic approached in the beginning of the undergraduate course, in curricular components or in extra-curricular activities, in order to provide the development of necessary support to experiencethe death-dying process of the customers.

  2. Diagnosing alternative conceptions of Fermi energy among undergraduate students

    Sharma, Sapna; Ahluwalia, Pardeep Kumar

    2012-01-01

    Physics education researchers have scientifically established the fact that the understanding of new concepts and interpretation of incoming information are strongly influenced by the preexisting knowledge and beliefs of students, called epistemological beliefs. This can lead to a gap between what students actually learn and what the teacher expects them to learn. In a classroom, as a teacher, it is desirable that one tries to bridge this gap at least on the key concepts of a particular field which is being taught. One such key concept which crops up in statistical physics/solid-state physics courses, and around which the behaviour of materials is described, is Fermi energy (ε F ). In this paper, we present the results which emerged about misconceptions on Fermi energy in the process of administering a diagnostic tool called the Statistical Physics Concept Survey developed by the authors. It deals with eight themes of basic importance in learning undergraduate solid-state physics and statistical physics. The question items of the tool were put through well-established sequential processes: definition of themes, Delphi study, interview with students, drafting questions, administration, validity and reliability of the tool. The tool was administered to a group of undergraduate students and postgraduate students, in a pre-test and post-test design. In this paper, we have taken one of the themes i.e. Fermi energy of the diagnostic tool for our analysis and discussion. Students’ responses and reasoning comments given during interview were analysed. This analysis helped us to identify prevailing misconceptions/learning gaps among students on this topic. How spreadsheets can be effectively used to remove the identified misconceptions and help appreciate the finer nuances while visualizing the behaviour of the system around Fermi energy, normally sidestepped both by the teachers and learners, is also presented in this paper.

  3. Undergraduate quantum mechanics: lost opportunities for engaging motivated students?

    Science.gov (United States)

    Johansson, Anders

    2018-03-01

    Quantum mechanics is widely recognised as an important and difficult subject, and many studies have been published focusing on students’ conceptual difficulties. However, the sociocultural aspects of studying such an emblematic subject have not been researched to any large extent. This study explores students’ experiences of undergraduate quantum mechanics using qualitative analysis of semi-structured interview data. The results inform discussions about the teaching of quantum mechanics by adding a sociocultural dimension. Students pictured quantum mechanics as an intriguing subject that inspired them to study physics. The study environment they encountered when taking their first quantum mechanics course was however not always as inspiring as expected. Quantum mechanics instruction has commonly focused on the mathematical framework of quantum mechanics, and this kind of teaching was also what the interviewees had experienced. Two ways of handling the encounter with a traditional quantum mechanics course were identified in the interviews; either students accept the practice of studying quantum mechanics in a mathematical, exercise-centred way or they distance themselves from these practices and the subject. The students who responded by distancing themselves experienced a crisis and disappointment, where their experiences did not match the way they imagined themselves engaging with quantum mechanics. The implications of these findings are discussed in relation to efforts to reform the teaching of undergraduate quantum mechanics.

    The Undergraduate Student Instrumentation Project (USIP) is a NASA program to engage undergraduate students in rigorous scientific research, for the purposes of innovation and developing the next generation of professionals for an array of fields. The program is student led and executed from initial ideation to research to the design and deployment of scientific payloads. The University of Houston has been selected twice to participate in the USIP programs. The first program (USIP_UH I) ran from 2013 to 2016. USIP_UH II started in January of this year, with funding starting at the end of May. USIP_UH I (USIP_UH II) at the University of Houston was (is) composed of eight (seven) research teams developing six (seven), distinct, balloon-based scientific instruments. These instruments will contribute to a broad range of geophysical sciences from Very Low Frequency recording and Total Electron Content to exobiology and ozone profiling. USIP_UH I had 12 successful launches with 9 recoveries from Fairbanks, AK in March 2015 and 4 piggyback flights with BARREL 3 from Esrange, Kiruna, Sweden in August, 2015. Additional flights with BARREL 4 will take place in August 2016. The great opportunity of this program is capitalizing on the proliferation of electronics miniaturization to create new generations of scientific instruments that are smaller and lighter than ever before. This situation allows experiments to be done more cheaply which ultimately allows many more experiments to be done.

    Paramedics rely on establishing a health provider-patient relationship with patients that promotes two-way communication, patient satisfaction, and facilitates appropriate patient assessment and treatment. Paramedics also must have an ability to empathize with patients and their family members in order to develop a successful health provider-patient relationship. The objective of this study was to assess paramedics' empathy and attitudes toward patients with specific conditions. This was a cross-sectional study using a convenience sample of first-, second-, and third-year, Australian undergraduate paramedic students. Student empathy levels were assessed using two standardized self-reporting instruments: the Jefferson Scale of Physician Empathy (JSPE) Health Professional (HP) version and the Medical Condition Regard Scale (MCRS). A total of 94 paramedic students participated in the study. The JSPE demonstrated that male paramedic students had higher mean empathy scores than did female paramedic students (113.25 and 107.5, respectively; P = .042). The JSPE empathy level scores were lowest among first-year paramedic students (mean = 107.53); age was not found to be a significant variable on empathy scores. The Medical Condition Regard Scale revealed lowest scores in compassion towards substance abuse (mean = 46.42). The results of this study provide the discipline of paramedic health care with useful data, and provide students, academics, and other educators with important information regarding the improvement of the health provider-patient relationship and paramedic education curriculum development.

    A major research thrust in science, technology, engineering, and mathematics (STEM) education is focused on how to retain students as STEM majors. The accumulation of seemingly insignificant negative experiences in STEM classes can, over time, lead STEM students to have a low sense of belonging in their disciplines, and this can lead to lower retention. In this paper, we explore how Judeo-Christian students in biology have experiences related to their religious identities that could impact their retention in biology. In 28 interviews with Judeo-Christian students taking undergraduate biology classes, students reported a religious identity that can conflict with the secular culture and content of biology. Some students felt that, because they are religious, they fall within a minority in their classes and would not be seen as credible within the biology community. Students reported adverse experiences when instructors had negative dispositions toward religion and when instructors were rigid in their instructional practices when teaching evolution. These data suggest that this may be a population susceptible to experiences of cultural conflict between their religious identities and their STEM identities, which could have implications for retention. We argue that more research should explore how Judeo-Christian students’ experiences in biology classes influence their sense of belonging and retention. PMID:28232586

    This paper reports on the main findings of a longitudinal study of the learning styles of one cohort of undergraduate pre-registration nursing students at an Irish university. The Honey and Mumford (2000a) Learning Styles Questionnaire was administered to a sample of students in their first (n=202) and final year of study (n=166), the final sample number (58) was based on matched pairs. The most common dominant learning style in first year was the dual learning category (35%) while a large proportion of the students (53%) in their final year had no dominant learning style. The preferred learning style of students in their first (69%) and final (57%) year was reflector. Learning styles were significantly different at the two time points and there was a significant relationship between some learning styles and students' age but not with academic achievement. Total scores of all learning styles showed significant improvements across the two time points of the study. An important implication for nurse education practice is the need for nurse educators to be aware of students' learning styles and in an attempt to maximise students' learning potential, utilise a range of teaching and learning methodologies and assessments that develop all learning styles.

    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).

    Drug use by drivers is a significant and growing highway safety problem. College students are an important population to understand drugged driving. The objective of this study was to examine correlates of drugged driving among undergraduate college students. We conducted an anonymous, confidential, 24-question survey at a large New England public university during the 2010-2011 academic year among undergraduates in courses that met a graduation requirement. Data include demographics; academics; housing status; lifestyle; personal values; high school/college drug use; and driving following alcohol use, drug use, or both; and as a passenger with a driver who used alcohol, drugs, or both. Descriptive statistics were calculated. Chi-square tests compared driver alcohol use, drug use, or both with demographic, academic, and lifestyle variables. Logistic regression analyses were performed with drugged driving as the dependent variable. Odds ratios and corresponding 95 percent confidence intervals were calculated for each of the potential explanatory variables in relation to the outcome. Four hundred forty-four of 675 students completed surveys (66% participation rate). Participants were representative of the student body with a mean age of 19.4 (±1.3 years), 51 percent male, 75 percent white, and 10 percent Hispanic. Seventy-eight percent lived on campus, 93 percent had a driver's license, and 37 percent had access to a car. Students disagreed that cannabinoids impair driving (18%) compared to other drugs (17%), stimulants (13%), depressants (11%), hallucinogens (8%), and alcohol (7%). Twenty-three percent drove after alcohol use and 22 percent drove after drug use. Forty-one percent reported having been a passenger with a driver who had been drinking and 37 percent with a driver using drugs. Drugged driving was more likely among males vs. females (30% vs. 14%, P college (50% vs. 8%, P confidence interval [CI]: 4.6-19.6) and best friends in college used drugs regularly

    2017-02-01

    Biology education is undergoing a transformation toward a more student-centered, inquiry-driven classroom. Many educators have designed engaging assignments that are designed to help undergraduate students gain exposure to the scientific process and data analysis. One of these types of assignments is use of a grant proposal assignment. Many instructors have used these assignments in lecture-based courses to help students process information in the literature and apply that information to a novel problem such as design of an antiviral drug or a vaccine. These assignments have been helpful in engaging students in the scientific process in the absence of an inquiry-driven laboratory. This commentary discusses the application of these grant proposal writing assignments to undergraduate biology courses. © FEMS 2017. All rights reserved.

    The purpose of this study was to describe undergraduate nursing students' attitudes toward mental health nursing and how these attitudes influenced their professional career choices in mental health nursing. A descriptive, online survey was utilized to examine students' perceptions of mental health nursing. A total of 229 junior and senior nursing students were recruited from eight nursing colleges in Midwestern United States to participate in this survey. Students of different ages, genders, ethnicities, and nursing programs did not report significantly different perceptions of: (a) knowledge of mental illness; (b) negative stereotypes; (c) interest in mental health nursing as a future career; and (d), and beliefs that psychiatric nurses provide a valuable contribution to consumers and the community. Negative stereotypes were significantly different between students who had mental health nursing preparation either in class (p=0.0147) or in clinical practice (p=0.0018) and students who had not. There were significant differences in anxiety about mental illness between students who had classes on mental health nursing (p=.0005), clinical experience (p=0.0035), and work experience in the mental health field (p=0.0012). Significant differences in an interest in a future career in mental health nursing emerged between students with and without prior mental health experience and between students with and without an interest in an externship program with p-values of 0.0012 and students have to mental health nursing through clinical experiences, theory classes, and previous work in the field, the more prepared they feel about caring for persons with mental health issues.

    Gourlay, Barbara Elas

    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

    The aim of this study was to evaluate the performance of undergraduates in their first contact with manual and rotary root canal instrumentation. Forty-two students who had never worked on a root canal before instrumented 42 extracted lower-incisors. Participants were assigned to one of two groups: Rotary instrumentation or manual instrumentation. Pre- and post-operative computed tomography scans were obtained with a 3-dimensional dental imaging system. Starting and finishing times of preparation were recorded. The cross-sectional area of the root canal was analyzed with 2-mm-below-the-apex initial and final transverse images recorded through a digital imaging system and analyzed with software to measure the initial and final area of the root canal in mm(2). Data from the cross-sectional area of the root canal and time spent were subjected to the Mann-Whitney's U-test (pcanal were observed (p=0.25). No accidents occurred. Undergraduate students showed good performance in their first contact with the manual and rotary instrumentation with regard to time spent and cross-sectional area of the root canal, with no operative accidents.

  17. Undergraduate engineering student experiences: Comparing sex, gender and switcher status

    Science.gov (United States)

    Fergen, Brenda Sue

    This dissertation explores undergraduate engineering experiences, comparing men with women and switchers with non-switchers. Factors related to a chilly academic climate and gender-role socialization are hypothesized to contribute to variations in men's and women's academic experiences and persistence rates. Both quantitative and qualitative data are utilized in an effort to triangulate the findings. Secondary survey data, acquired as result of a 1992 Academic Environment Survey, were utilized to test the hypothesis that sex is the most important predictor (i.e., demographic variable) of perceptions of academic climate. Regression analyses show that sex by itself is not always a significant determinant. However, when sex and college (engineering vs. other) are combined into dummy variables, they are statistically significant in models where sex was not significant alone. This finding indicates that looking at sex differences alone may be too simplistic. Thirty personal interviews were conducted with a random stratified sample of undergraduate students from the 1993 engineering cohort. The interview data indicate that differences in childhood socialization are important. With regard to persistence, differences in socialization are greater for switchers vs. non-switchers than men vs. women. Thus, gender-role socialization does not appear to play as prominent a role in women's persistence as past literature would indicate. This may be due to the self-selection process that occurs among women who choose to pursue engineering. Other aspects of childhood socialization such as parents' level of educational and occupation, students' high school academic preparation and knowledge of what to expect of college classes appear to be more important. In addition, there is evidence that, for women, male siblings play an important role in socialization. There is also evidence that women engineering students at Midwestern University face a chilly academic climate. The factors which

    Purpose Effective clinical leadership is crucial to avoid failings in the delivery of safe health care, particularly during a period of increasing scrutiny and cost-constraints for the National Health Service (NHS). However, there is a paucity of leadership training for health-care students, the future leaders of the NHS, which is due in part to overfilled curricula. The purpose of this study was to assess the impact of student-led leadership training for the benefit of fellow students. Design/methodology/approach To address this training gap, a group of multiprofessional students organised a series of large-group seminars and small-group workshops given by notable health-care leaders at a London university over the course of two consecutive years. Findings The majority of students had not previously received any formal exposure to leadership training. Feedback post-events were almost universally positive, though students expressed a preference for experiential teaching of leadership. Working with university faculty, an inaugural essay prize was founded and student members were given the opportunity to complete internships in real-life quality improvement projects. Originality/value Student-led teaching interventions in leadership can help to fill an unmet teaching need and help to better equip the next generation of health-care workers for future roles as leaders within the NHS.

    This study aimed to assess knowledge and skills in a respiratory physiology course in traditional versus problem-based learning (PBL) groups in two different medical schools. Two different undergraduate medical schools were selected for this study. The first medical school followed the traditional [lecture-based learning (LBL)] curriculum, and the second medical school followed the PBL curriculum. Sixty first-year male medical students (30 students from each medical school) volunteered; they were apparently healthy and of the same age, sex, nationality, and regional and cultural background. Students were taught respiratory physiology according to their curriculum for a period of 2 wk. At the completion of the study period, knowledge was measured based on a single best multiple-choice question examination, and skill was measured based on the objective structured practical examination in the lung function laboratory (respiratory physiology). A Student's t-test was applied for the analysis of the data, and the level of significance was set at P < 0.05. Students belonging to the PBL curriculum obtained a higher score in the multiple-choice question examination (P = 0.001) and objective structured practical examination (P = 0.0001) compared with traditional (LBL) students. Students in the PBL group obtained significantly higher knowledge and skill scores in the respiratory physiology course compared with students in the traditional (LBL) style of medical schools.

    The average retention rate for students enrolled in undergraduate athletic training programs (ATPs) nationwide has been reported to be 81%, and slightly more than half of program directors (PDs) have indicated that retention of athletic training students (ATSs) is a problem. However, why PDs do or do not believe ATS retention is problematic is unknown. To determine why PDs do or do not believe ATS retention is problematic. Qualitative study. Undergraduate ATPs. We obtained responses from 177 of the 343 PDs (51.6%). Using data saturation as a guide, we randomly selected 16 PDs from the survey responses to participate in follow-up telephone interviews; 8 believed retention was a problem and 8 did not. During audio-recorded telephone interviews, we asked PDs why they thought retention was or was not a problem for athletic training education. Following verbatim transcription, we used grounded theory to analyze the interview data and maintained trustworthiness by using intercoder agreement, member checks, and peer review. Program directors believed that retaining ATSs was a problem because students lack information regarding athletic training and the rigor of the ATP. Program directors were consistent in their perception that ATPs do not have a retention challenge because of the use of a secondary admissions process. This finding was likely based on personal use of a secondary admissions process in the ATPs these PDs lead. Program directors who lead ATPs that struggle to retain ATSs should consider using a secondary admissions process. During the preprofessional phase of the ATP, faculty and staff should work to socialize students to the demands of the ATP and the professional lives of athletic trainers.

    Langdon, G. S.; Balchin, K.; Mufamadi, P.

    2010-10-01

    This paper examines the development of risk awareness among undergraduate students studying mechanical engineering at a South African university. A questionnaire developed at the University of Liverpool was modified and used on students from the first, second and third year cohorts to assess their awareness in the areas of professional responsibility, risk assessment, techniques for reducing risk and potential exposure to hazards and risk in the workplace. Students performed best in hazard identification in the workplace. The student performance was similar in the first and second years, but a significant improvement was evident towards the end of the third year. This was attributed to the third year design curriculum, which formally covers certain aspects of risk awareness, including the ones showing improved performance. The results were compared to those obtained from the University of Liverpool - the UK students outperformed their South African counterparts. It is recommended that teaching interventions regarding health and safety be introduced earlier in the South African Mechanical Engineering curriculum to address this deficiency.

    Full Text Available Evidence-based practice is the foundation of nutrition and dietetics. To effectively apply evidence-based practice, health professionals must understand the basis of research. Previous work has identified the lack of involvement of dietitians in research. As part of a curriculum redevelopment in undergraduate nutrition and dietetics courses, research skill teaching was enhanced. This study evaluated the effect of a new, year two level nutrition research methods unit on the perceived research skills of students. The unit consisted of two key components: a student-led class research project and a small group systematic literature review. Prior to commencement and on completion of the course, students completed a modified version of the Research Skills Questionnaire. Results demonstrated that self-perceived competence increased by a small degree in a set of specific research skills as well as in broader skills such as information gathering and handling, information evaluation, ability to work independently, and critical thinking. The new research unit was also evaluated highly on a student satisfaction survey. Despite these positive findings, students indicated that their general feelings towards research or a career in research were unchanged. In summary, this unit enhanced students’ perceived research skills. Further exploration of students’ attitude towards research is warranted.

    The rapid growth and accessibility of social networking websites has fundamentally changed the way people manage information about their personal and professional lives. In particular, it has been suggested that interaction in virtual communities erodes elements of responsibility, accountability and social trust that build traditionally meaningful communities. The purpose of this study was to investigate how undergraduate medical students use the social network website Facebook, and to identify any unprofessional behaviour displayed online. A voluntary anonymous online survey was devised by the University of Liverpool, and emailed to students. Question topics included the use of Facebook, privacy settings, groups relating to the course and professional behaviours. Results were input to spss for analysis. The response rate was 31 per cent (n = 56). The majority of respondents did have a Facebook account and admitted there were photos they found embarrassing on the site. Over half of the respondents reported they had seen unprofessional behaviour by their colleagues on Facebook. Although students say that they are aware of the UK's General Medical Council (GMC) guidance, unprofessional behaviour is still demonstrated on the site. This research highlights the issue of social networking websites and professionalism amongst medical students. Further guidance from the GMC and medical schools should remind students that images and information placed on social networking sites is in the public domain, and could impact upon their professional reputation and identity. © Blackwell Publishing Ltd 2010.

    Full Text Available Objectives: This study aimed to evaluate attitudes, perceptions and perceived barriers towards health research among Saudi Arabian undergraduate medical students. Methods: This cross-sectional study took place between August and October 2014 and included 520 students from five medical schools across Saudi Arabia. An anonymous online survey with 21 close-ended questions was designed to assess students’ attitudes towards research, contribution to research-related activities, awareness of the importance of research, perception of available resources/opportunities for research, appreciation of medical students’ research contributions and perceived barriers to research. Responses were scored on a 5-point Likert scale. Results: A total of 401 students participated in the study (response rate: 77.1%. Of these, 278 (69.3% were female. A positive attitude towards research was reported by 43.9% of the students. No statistically significant differences were observed between genders with regards to attitudes towards and available resources for research (P = 0.500 and 0.200, respectively. Clinical students had a significantly more positive attitude towards research compared to preclinical students (P = 0.007. Only 26.4% of the respondents believed that they had adequate resources/opportunities for research. According to the students, perceived barriers to undertaking research included time constraints (n = 200; 49.9%, lack of research mentors (n = 95; 23.7%, lack of formal research methodology training (n = 170; 42.4% and difficulties in conducting literature searches (n = 145; 36.2%. Conclusion: Less than half of the surveyed Saudi Arabian medical students had a positive attitude towards health research. Medical education policies should aim to counteract the barriers identified in this study.

  6. Analysis of Student Performance in Peer Led Undergraduate Supplements

    Gardner, Linda M.

    Foundations of Chemistry courses at the University of Kansas have traditionally accommodated nearly 1,000 individual students every year with a single course in a large lecture hall. To develop a more student-centered learning atmosphere, Peer Led Undergraduate Supplements (PLUS) were introduced to assist students, starting in the spring of 2010. PLUS was derived from the more well-known Peer-Led Team Learning with modifications to meet the specific needs of the university and the students. The yearlong investigation of PLUS Chemistry began in the fall of 2012 to allow for adequate development of materials and training of peer leaders. We examined the impact of academic achievement for students who attended PLUS sessions while controlling for high school GPA, math ACT scores, credit hours earned in high school, completion of calculus, gender, and those aspiring to be pharmacists (i.e., pre-pharmacy students). In a least linear squares multiple regression, PLUS participants performed on average one percent higher on exam scores for Chemistry 184 and four tenths of a percent on Chemistry 188 for each PLUS session attended. Pre-pharmacy students moderated the effect of PLUS attendance on chemistry achievement, ultimately negating any relative gain associated by attending PLUS sessions. Evidence of gender difference was demonstrated in the Chemistry 188 model, indicating females experience a greater benefit from PLUS sessions. Additionally, an item analysis studied the relationship between PLUS material to individual items on exams. The research discovered that students who attended PLUS session, answered the items correctly 10 to 20 percent more than their comparison group for PLUS interrelated items and no difference to 10 percent for non-PLUS related items. In summary, PLUS has a positive effect on exam performance in introductory chemistry courses at the University of Kansas.

    The present study investigated the association between level of education and self-reported levels of anxiety regarding death of self and others among undergraduate students (n = 149) and graduate students (n = 92). Participants completed the Multidimensional Fear of Death Scale (MFODS) and the Revised Death Anxiety Scale (RDAS). Although undergraduate and graduate students did not differ on Fear of Being Destroyed, graduate students reported lower levels of death anxiety on all remaining measures. Suggestions for future research and implications are discussed.

    2017-12-01

    This study aims to improve the experiment implementation quality and analytical thinking skills of undergraduate students through guided-inquiry laboratory experiments. This study was a classroom action research conducted in three cycles. The study has been carried out with 38 undergraduate students of the second semester of Biology Education Department of State Islamic Institute (SII) of Tulungagung, as a part of Chemistry for Biology course. The research instruments were lesson plans, learning observation sheets and undergraduate students' experimental procedure. Research data were analyzed using quantitative-descriptive method. The increasing of analytical thinking skills could be measured using gain score normalized and statistical paired t-test. The results showed that guided-inquiry laboratory experiments model was able to improve both the experiment implementation quality and the analytical thinking skills. N-gain score of the analytical thinking skills was increased, in spite of just 0.03 with low increase category, indicated by experimental reports. Some of undergraduate students have had the difficulties in detecting the relation of one part to another and to an overall structure. The findings suggested that giving feedback the procedural knowledge and experimental reports were important. Revising the experimental procedure that completed by some scaffolding questions were also needed.

    2009-12-01

    Evidence-based thinking is essential both to science and to the development of effective educational programs. Thus assessment of student learning—gathering evidence about the nature and depth of students’ learning gains, and about how they arise—is a centerpiece of any effective undergraduate research (UR) program. Assessment data can be used to monitor progress, to diagnose problems, to strengthen program designs, and to report both good outcomes and strategies to improve them to institutional and financial stakeholders in UR programs. While the positive impact of UR on students’ educational, personal and professional development has long been a matter of faith, only recently have researchers and evaluators developed an empirical basis by which to identify and explain these outcomes. Based on this growing body of evidence, URSSA, the Undergraduate Research Student Self-Assessment, is a survey tool that departments and programs can use to assess student outcomes of UR. URSSA focuses on what students learn from their UR experience, rather than whether they liked it. Both multiple-choice and open-ended items focus on students’ gains from UR, including: (1) skills such as lab work and communication; (2) conceptual knowledge and linkages among ideas in their field and with other fields; (3) deepened understanding of the intellectual and practical work of science; (4) growth in confidence and adoption of the identity of scientist; (5) preparation for a career or graduate school in science; and (6) greater clarity in understanding what career or educational path they might wish to pursue. Other items probe students’ participation in important activities that have been shown to lead to these gains; and a set of optional items can be included to probe specific program features that may supplement UR (e.g. field trips, career seminars, housing arrangements). The poster will describe URSSA's content, development, validation, and use. For more information about

  14. Mathematical literacy in Plant Physiology undergraduates: results of interventions aimed at improving students' performance

    Vila, Francisca; Sanz, Amparo

    2013-09-01

    The importance of mathematical literacy in any scientific career is widely recognized. However, various studies report lack of numeracy and mathematical literacy in students from various countries. In the present work, we present a detailed study of the mathematical literacy of Spanish undergraduate students of Biology enrolled in a Plant Physiology course. We have performed individual analyses of results obtained during the period 2000-2011, for questions in the examinations requiring and not requiring mathematical skills. Additionally, we present the outcome of two interventions introduced with the aim of helping students improve their prospects for success in the course. Our results confirm previous research showing students' deficiencies in mathematical skills. However, the scores obtained for mathematical questions in the examinations are good predictors of the final grades attained in Plant Physiology, as there are strong correlations at the individual level between results for questions requiring and not requiring mathematical skills. The introduction of a laboratory session devoted to strengthening the application of students' previously acquired mathematical knowledge did not change significantly the results obtained for mathematical questions. Since mathematical abilities of students entering university have declined in recent years, this intervention may have helped to maintain students' performance to a level comparable to that of previous years. The outcome of self-assessment online tests indicates that although Mathematics anxiety is lower than during examinations, the poor results obtained for questions requiring mathematical skills are, at least in part, due to a lack of self-efficacy.

    Al-Ismaily, Said; Al-Maktoumi, Ali; Kacimov, Anvar

    2015-04-01

    Undergraduates, majoring in soil sciences (SS), have a broad holistic role because SS integrates several intertwined geo-environmental/ecological and socio-economical aspects. Consequently, students have to learn how the information, advice, practices and expertise, pertinent to food security, water shortage, hydropedology, among others amalgamate through SS . Hence, university SS-programs should incorporate public outreach activities. We present experience at Sultan Qaboos University (SQU) in Oman on how to develop an effective public outreach program that can be implemented by undergraduate students. Our strategy has three components : (i) offering a course Soil and Water Tour (SWAE 4110) of hydropedology nature that integrates field, laboratory-work, and presentation-extension activities; the course is research-oriented and designed to provide opportunities for students to practice their metacognitive abilities and critical thinking; the course is offered by the Department of Soils, Water & Agricultural Engineering (SWAE), (ii) Training and involving the undergraduates in planning and conducting enjoyable, interactive, and effective workshops for school pupils; a training workshop on "Soils" was conducted for pupils (a total 300 participants, grades 7-9) and teachers aiming to unveil the secrets and the role of soil in ecosystems; workshop was organized by the SWAE Students Society (iii) Guiding the undergraduates on the best practice for raising funds for their outreach activities (e.g. the undergraduates secured funds for the workshop on "Soils", which was sponsored by Muscat Municipality, a governmental agency, and several private companies such as HMR Consultants, Metal Engineering L.L.C and Bauer Nimr LLC); SS students were mentored in submission of research proposals to the national research agency (e.g. FURAP program of The Research Council, TRC, WWW.trc.gov.om).

    One of the main tools to optimize antibiotics use is education of prescribers. The aim of this article is to study undergraduate education in the field of infectious diseases, antimicrobial resistance and antibiotic stewardship from the perspective of Spanish medical students. An anonymous online questionnaire was distributed among sixth grade students using different channels in Europe, within the ESGAP Student-Prepare survey. The questionnaire included 45 questions about knowledge, attitudes and perceptions about diagnosis, bacterial resistance, use of antibiotics and undergraduate training in infectious diseases. We present here the Spanish results. A total of 441 surveys were received from 21 medical schools. A total of 374 responses (84.8%) were obtained from the 8 most represented faculties, with a response rate of 28.9%. Most students felt adequately prepared to identify clinical signs of infection (418; 94.8%) and to accurately interpret laboratory tests (382; 86.6%). A total of 178 (40.4%) acknowledged being able to choose an antibiotic with confidence without consulting books or guidelines. Only 107 (24.3%) students considered that they had received sufficient training in judicious use of antibiotics. Regarding learning methods, the discussion of clinical cases, infectious diseases units rotatories and small group workshops were considered the most useful, being evaluated favorably in 76.9%, 76% and 68.8% of the cases. Medical students feel more confident in the diagnosis of infectious diseases than in antibiotic treatment. They also feel the need to receive more training in antibiotics and judicious antibiotic use.

    Full Text Available Due to the fact that critical thinking and problem solving skills are essential components of educational and social lives of individuals, this present study which investigate critical thinking and problem solving skills of undergraduate students of nursing was planned. This is a descriptive study. The study population consisted of undergraduate nursing students of a university during the 2011-2012 academic year. Any specific sampling method was not determined and only the voluntary students was enrolled in the study . Several participants were excluded due to incomplete questionnaires, and eventually a total of 231 nursing students were included in the final sampling. Socio Demographic Features Data Form and the California Critical Thinking Disposition Scale and Problem Solving Inventory were used for data collection. The mean age of 231 subjects (148 girls, 83 boys was 21.34. The mean score of critical thinking was 255.71 for the first-grade, 255.57 for the second-grade, 264.73 for the third-grade, and 256.468 for the forth-grade students. The mean score of critical thinking was determined as 257.41 for the sample, which can be considered as an average value. Although there are mean score differences of critical thinking between the classes , they were not statistically significant (p> 0.05. With regard to the mean score of problem solving, the first-grade students had 92.86, the second-grade students had 94. 29, the third-grade students had 87.00, and the forth-grade students had 92.87. The mean score of problem solving was determined as 92.450 for the sample. Although there are differences between the classes in terms of mean scores of problem solving, it was not found statistically significant (p> 0.05. In this study, statistically significant correlation could not be identified between age and critical thinking skills of the subjects (p>0.05. However, a negative correlation was identified at low levels between critical thinking skills and

    At the beginning of academic year 2007-08, staff in the Department of Physics and Astronomy at the University of Glasgow started to implement a number of substantial changes to the administration of the level 1 physics undergraduate class. The main aims were to improve the academic performance and progression statistics. With this in mind, a comprehensive system of learning support was introduced, the main remit being the provision of an improved personal contact and academic monitoring and support strategy for all students at level 1. The effects of low engagement with compulsory continuous assessment components had already been observed to have a significant effect on students sitting in the middle of the grade curve. Analysis of data from the 2007-08 class showed that even some nominally high-achieving students achieved lowered grades due to the effects of low engagement. Nonetheless, academic and other support measures put in place during 2007-08 played a part in raising the passrate for the level 1 physics class by approximately 8% as well as raising the progression rate by approximately 10%.

  7. Pre-Nursing Students Perceptions of Traditional and Inquiry Based Chemistry Laboratories

    Science.gov (United States)

    Rogers, Jessica

    This paper describes a process that attempted to meet the needs of undergraduate students in a pre-nursing chemistry class. The laboratory was taught in traditional verification style and students were surveyed to assess their perceptions of the educational goals of the laboratory. A literature review resulted in an inquiry based method and analysis of the needs of nurses resulted in more application based activities. This new inquiry format was implemented the next semester, the students were surveyed at the end of the semester and results were compared to the previous method. Student and instructor response to the change in format was positive. Students in the traditional format placed goals concerning technique above critical thinking and felt the lab was easy to understand and carry out. Students in the inquiry based lab felt they learned more critical thinking skills and enjoyed the independence of designing experiments and answering their own questions.

  9. Epistemologies and scientific reasoning skills among undergraduate science students

    Science.gov (United States)

    Mollohan, Katherine N.

    Non-cognitive factors such as students' attitudes and beliefs toward a subject and their proficiency in scientific reasoning are important aspects of learning within science disciplines. Both factors have been studied in relation to science education in various discplines. This dissertation presents three studies that investigate student epistemologies and scientific reasoning in the domain of biology education. The first study investigated students' epistemic viewpoints in two introductory biology courses, one for science majors and one for non-science majors. This quantitative investigation revealed that the majors exhibited a negative shift in their attitudes and beliefs about biology and learning biology during a semester of introductory instruction. However, the non-science majors did not exhibit a similar shift. If fact, the non-science majors improved in their attitudes and beliefs during a semester of instruction, though not significantly so. The second study expands epistemological research to a population that has often been left out of this work, that is, intermediate-level biology majors. Quantitative and qualitative data was collected to reveal that junior and senior ranked students for the most part were able to characterize their views about biology and learning biology, and were able to associate factors with their epistemic improvement. Finally, the third study expands epistemology research further to determine if scientific reasoning and student attitudes and beliefs about learning science (specifically biology) are related. After a description of how various science and engineering majors compare in their scientific reasoning skills, this study indicated that among intermediate level biology majors there is no relationship between scientific reasoning skills and epistemologies, nor is there a relationship with other educational factors, including the number of courses taken during an undergraduate career, cumulative GPA, and standardized test

  10. A new method of measuring gravitational acceleration in an undergraduate laboratory program

    Wang, Qiaochu; Wang, Chang; Xiao, Yunhuan; Schulte, Jurgen; Shi, Qingfan

    2018-01-01

    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.

    Little attention has been paid to understanding faculty-student productivity via undergraduate research from the faculty member's perspective. This study examines predictors of faculty-student publications resulting from mentored undergraduate research, including measures of faculty-student collaboration, faculty commitment to undergraduate students, and faculty characteristics. Generalized estimating equations were used to analyze data from 468 faculty members across 13 research-intensive institutions, collected by a cross-sectional survey in 2013/2014. Results show that biomedical faculty mentors were more productive in publishing collaboratively with undergraduate students when they worked with students for more than 1 year on average, enjoyed teaching students about research, had mentored Black students, had received more funding from the National Institutes of Health, had a higher H-index scores, and had more years of experience working in higher education. This study suggests that college administrators and research program directors should strive to create incentives for faculty members to collaborate with undergraduate students and promote faculty awareness that undergraduates can contribute to their research. © 2017 D.

    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.

    Admission to a professional program marks the beginning of fulfilling a career goal. However, the rigors of professional education can be demanding. Stress, depression, and anxiety (SDA) can interfere with learning, affect academic performance, and impair clinical practice performance. Studies report a general increase in the severity of and extent of mental health problems among college/university students. The literature regarding nursing students' mental health distress identifies academic and personal sources of stress and coping efforts, with emphasis on the stress and anxiety associated with clinical practice. This cross-sectional descriptive exploratory study investigated levels of SDA among nursing students in 3 years of a university-based program. The association between quality of life indicators including known stressors, such as financial concerns and balance between school and personal life, and SDA was also investigated. Through an online survey, 437 participants from one mid-western Canadian undergraduate nursing program completed the Depression Anxiety Stress Scales and provided data on quality of life indicators and demographic information. Participants also were invited to provide narrative data about their experiences with SDA. This article will present significant findings including: levels of SDA; comparisons between our sample and a normative sample on the dimensions of SDA; and the results of multiple regression analysis identifying significant predictors of each dimension. Themes from the qualitative comments from 251 of the participants were identified and added depth and clarity to the quantitative findings. The predominant themes represented were: perceptions of clinical practice, coping, personal issues, and balancing school, work, and personal life. Implications and recommendations for curriculum design, ensuring students understand program expectations prior to admission, and enhancing accessibility to mental health/support services

    Full Text Available Background: Ultrasonography protocols are easy to learn, frequently used in emergency medicine, and could be useful for inexperienced doctors. In this field, only a few protocols are needed to give an initial diagnosis and to start fast and proper treatment. Until now, only Focused Assessment with Sonography for Trauma (FAST protocol training studies have been reported in the medical literature. Our point-of-care course, comprised of extended FAST, lung scan and ocular scan trainings. The students’ curriculum usually does not include such ultrasonography courses, thus, we wanted to check its utility for the undergraduate medical students. Methods: Training lasted six days and consisted of two parts: 22 hours of theoretical classes and 18 hours of practical activities, all trained and evaluated by six experienced medical doctors. Eighty-five elected students completed pre- and post-study questionnaires about emergency ultrasonography and passed the practical final exam. Results: Eighty-five participants of the course were present in the pre- and final test. Final test scores of theoretical and practical exams were significantly higher after the training (58% vs. 87%; n=85; p<0.01. Answers for the questions related to FAST and EFAST (extended FAST were correct irrespective of completion of the course. A question regarding the sonographic evaluation of body fluid incontinence was found to be the most difficult for students. After the course, 96.5% of participants were able to complete an EFAST scan at an adequate level of performance in under two minutes. Conclusion: Results show that medical students significantly extended their knowledge about point-of-care emergency medicine ultrasonography and acquired practical skills during the course. Emergency medicine ultrasonography courses could be included into medical students’ curricula.

    "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.

    On the surface of the moon and Mars there are hundreds of skylights, which are collapsed holes that are believed to lead to underground caves. This research uses Vision, Inertial, and LIDAR sensors to build a high resolution model of a skylight as a landing vehicle flies overhead. We design and fabricate a pit modeling instrument to accomplish this task, implement software, and demonstrate sensing and modeling capability on a suborbital reusable launch vehicle flying over a simulated pit. Future missions on other planets and moons will explore pits and caves, led by the technology developed by this research. Sensor software utilizes modern graph-based optimization techniques to build 3D models using camera, LIDAR, and inertial data. The modeling performance was validated with a test flyover of a planetary skylight analog structure on the Masten Xombie sRLV. The trajectory profile closely follows that of autonomous planetary powered descent, including translational and rotational dynamics as well as shock and vibration. A hexagonal structure made of shipping containers provides a terrain feature that serves as an appropriate analog for the rim and upper walls of a cylindrical planetary skylight. The skylight analog floor, walls, and rim are modeled in elevation with a 96% coverage rate at 0.25m2 resolution. The inner skylight walls have 5.9cm2 color image resolution and the rims are 6.7cm2 with measurement precision superior to 1m. The multidisciplinary student team included students of all experience levels, with backgrounds in robotics, physics, computer science, systems, mechanical and electrical engineering. The team was commited to authentic scientific experimentation, and defined specific instrument requirements and measurable experiment objectives to verify successful completion.This work was made possible by the NASA Undergraduate Student Instrument Project Educational Flight Opportunity 2013 program.

    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.

    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.
