    Full Text Available Developing learners’ writing skills has been of concern for a long time in education. Students studying English in our educational institutions have been found to face problems mainly in writing, making them unable to cope with the institution’s literacy expectations. However, these students may be able to develop writing skills significantly with positive instructional attitudes towards the errors they make and awareness on the teachers’ part of learner problems. That is why they should improve classroom writing instruction to address the serious problem of students writing difficult. Teaching strategies has shown a dramatic effect on the quality of students’ writing. Strategy instruction involves explicitly and systematically teaching steps necessary to use strategies independently. The following table will explain the above ideas.

  4. Strategies for Teaching Astronomy

    Bennett, J.

    2000-12-01

    No matter whether you are teaching school children, undergraduates, or colleagues, a few key strategies are always useful. I will present and give examples for the following five key strategies for teaching astronomy. 1. Provide a Contextual Framework: It is much easier to learn new facts or concepts if they can be ``binned" into some kind of pre-existing mental framework. Unless your listeners are already familiar with the basic ideas of modern astronomy (such as the hierarchy of structure in the universe, the scale of the universe, and the origin of the universe), you must provide this before going into the details of how we've developed this modern picture through history. 2. Create Conditions for Conceptual Change: Many people hold misconceptions about astronomical ideas. Therefore we cannot teach them the correct ideas unless we first help them unlearn their prior misconceptions. 3. Make the Material Relevant: It's human nature to be more interested in subjects that seem relevant to our lives. Therefore we must always show students the many connections between astronomy and their personal concerns, such as emphasizing how we are ``star stuff" (in the words of Carl Sagan), how studying other planets helps us understand our own, and so on. 4. Limit Use of Jargon: The number of new terms in many introductory astronomy books is larger than the number of words taught in many first courses in foreign language. This means the books are essentially teaching astronomy in a foreign language, which is a clear recipe for failure. We must find ways to replace jargon with plain language. 5. Challenge Your Students: Don't dumb your teaching down; by and large, students will rise to meet your expectations, as long as you follow the other strategies and practice good teaching.

    2012-02-01

    Full Text Available Abstract Background Over the past few years, information retrieval has become more and more professionalized, and information specialists are considered full members of a research team conducting systematic reviews. Research groups preparing systematic reviews and clinical practice guidelines have been the driving force in the development of search strategies, but open questions remain regarding the transparency of the development process and the available resources. An empirically guided approach to the development of a search strategy provides a way to increase transparency and efficiency. Methods Our aim in this paper is to describe the empirically guided development process for search strategies as applied by the German Institute for Quality and Efficiency in Health Care (Institut für Qualität und Wirtschaftlichkeit im Gesundheitswesen, or "IQWiG". This strategy consists of the following steps: generation of a test set, as well as the development, validation and standardized documentation of the search strategy. Results We illustrate our approach by means of an example, that is, a search for literature on brachytherapy in patients with prostate cancer. For this purpose, a test set was generated, including a total of 38 references from 3 systematic reviews. The development set for the generation of the strategy included 25 references. After application of textual analytic procedures, a strategy was developed that included all references in the development set. To test the search strategy on an independent set of references, the remaining 13 references in the test set (the validation set were used. The validation set was also completely identified. Discussion Our conclusion is that an objectively derived approach similar to that used in search filter development is a feasible way to develop and validate reliable search strategies. Besides creating high-quality strategies, the widespread application of this approach will result in a

    Fink, D J

    1980-07-01

    University teaching hospitals face increasing competition from community hospitals, expanding regulation of health care, a rising tide of consumerism, and in many cases a declining urban population base. These problems, which may threaten the teaching hospital's ability to continue tertiary care, teaching, and research functions, may be solved with the aid of new marketing strategies. In developing its marketing strategy, a hospital must assess its strengths and weaknesses, specify its goals in measurable terms, implement tactics to achieve these goals, and evaluate its marketing program. The strategies should be directed toward achieving better relationships with institutions, practitioners, and surrounding communities and increasing patient, visitor, and employee satisfaction. A wide variety of programs can be used to reach these goals and to help teaching hospitals meet the competitive challenges of this decade.

    Feng Teng

    2014-11-01

    Full Text Available Abstract This article presents an overview of current research on second language vocabulary learning and proposes eight strategies for teaching and learning vocabulary. First, to facilitate effective vocabulary teaching, choosing high-frequency words is essential. Teachers of vocabulary also need to add explicit, intentional teaching to incidental learning. In addition, vocabulary learning strategies including morphological awareness and lexical inference provides a platform by which learners can improve both receptive and productive vocabulary knowledge. This article also suggests that productive vocabulary knowledge needs more attention than receptive vocabulary knowledge, and that available textbooks seldom address vocabulary sufficiently. In summary, it is very important for all learners and teachers to acknowledge that learning vocabulary is incremental in nature, and we should develop a principled, long-term program for teaching and learning vocabulary.

    The objective of this study was to determine effective teaching strategies and methods of delivery for patient education (PE). A systematic review was conducted and reviews with or without meta-analyses, which examined teaching strategies and methods of delivery for PE, were included. Teaching strategies identified are traditional lectures, discussions, simulated games, computer technology, written material, audiovisual sources, verbal recall, demonstration, and role playing. Methods of delivery focused on how to deliver the teaching strategies. Teaching strategies that increased knowledge, decreased anxiety, and increased satisfaction included computer technology, audio and videotapes, written materials, and demonstrations. Various teaching strategies used in combination were similarly successful. Moreover, structured-, culturally appropriate- and patient-specific teachings were found to be better than ad hoc teaching or generalized teaching. Findings provide guidance for establishing provincial standards for the delivery of PE. Recommendations concerning the efficacy of the teaching strategies and delivery methods are provided.

    Medical Education, according to the constructivist education paradigm, puts students as the protagonists of the teaching and learning process. It demands changes in the practice of teaching. However, it is unclear whether this new model is coherent with the teachers’ ways to cope with learning. To analyze the relationship between teaching practices and learning strategies among teachers of health careers in Chilean universities. The Teaching Practices Questionnaire and Learning Strategies Inventory of Schmeck were applied to 200 teachers aged 24 to 72 years (64% females). Teachers use different types of teaching practices. They commonly use deep and elaborative learning strategies. A multiple regression analysis showed that learning strategies had a 13% predictive value to identify student-centered teaching, but they failed to predict teacher-centered teaching. Teaching practices and learning strategies of teachers are related. Teachers frequently select constructivist model strategies, using different teaching practices in their work.

    The educational system depends upon the quality and performance of their faculty and should therefore be process of continuous improvement. To assess the teaching performance of the Public Health professors, at the Faculty of Medicine, UNAM through three strategies. Justification study. The evaluation was conducted under a mediational model through three strategies: students' opinion assessment, self-assessment and students' academic achievement. We applied descriptive statistics, Student t test, ANOVA and Pearson correlation. Twenty professors were evaluated from the Public Health department, representing 57% of all them who teach the subject. The professor's performance was highly valued self-assessment compared with assessment of student opinion, was confirmed by statistical analysis the difference was significant. The difference amongst the three evaluation strategies became more evident between self-assessment and the scores obtained by students in their academic achievement. The integration of these three strategies offers a more complete view of the teacher's performance quality. Academic achievement appears to be a more objective strategy for teaching performance assessment than students' opinion and self-assessment.

  1. Repurposeable Learning Objects Linked to Teaching and Learning Styles

    Directory of Open Access Journals (Sweden)

    Jeremy Dunning

    2004-02-01

    Full Text Available Multimedia learning objects are an essential component of high quality, technology-mediated instruction. Learning objects allow the student to use the content learned in a particular part of a course and; 1. demonstrate mastery of the content, 2. apply that knowledge to solving a problem, and 3. use the content in a critical thinking exercise that both demonstrates mastery and allows the student to place the content within the context of the larger topic of the course. The difficulty associated with the use of learning objects on a broad scale is that they require programming skills most professors and instructors do not possess. Learning objects also tend to be custom productions and are defined in terms of the programming and code terminology, further limiting the professor's ability to understand how they are created. Learning objects defined in terms of styles of learning and teaching allow professors and instructors to develop a deeper understanding of the learning objects and the design process. A set of learning objects has been created that are designed for some of the important styles of learning and teaching. They include; visual learning, writing skills, critical thinking, time-revealed scenarios, case studies and empirical observation. The learning objects are designed and described in terms that the average instructor can readily understand , redesign and incorporate into their own courses. They are also designed in such a way that they can readily be repurposed for new applications in other courses and subject areas, with little or no additional programming.

    Full Text Available   This research aimed at knowing the ability of applying Synectics strategy in teaching rhetoric in Arabic language at secondary schools and universities   Synectics is identifying as a process of joining elements that has no obvious relationship using the rhetoric arts, especially “metaphor” in addition to logical arts especially “analogy,” within a methodology aims to reach creative solutions to problems. This definition is completely similar to Arabic rhetoric such as analogy and metaphor.   When metaphor in language contains aesthetic and rhetorical values in expression, it carries explanatory connotations in philosophy and science which is the using of a specific experience to shed the light on another one. It also helps us to comprehend, insight and clarifying and explaining the concepts. And what we mean with analogy in Arabic language is nearer to simile which is one of the rhetoric arts.   This research will review the Synectics strategy, how the western scientists applied it to develop creativity, and to what extent it is suitable to teach Arabic rhetoric subject in the university and secondary stage. In addition, It will provide application forms about applying Synectics strategy which will at the same time increase creativity of the students in all fields.

  4. Planning Robotic Manipulation Strategies for Sliding Objects

    Science.gov (United States)

    Peshkin, Michael A.

    Automated planning of grasping or manipulation requires an understanding of both the physics and the geometry of manipulation, and a representation of that knowledge which facilitates the search for successful strategies. We consider manipulation on a level conveyor belt or tabletop, on which a part may slide when touched by a robot. Manipulation plans for a given part must succeed in the face of two types of uncertainty: that of the details of surfaces in contact, and that of the initial configuration of the part. In general the points of contact between the part and the surface it slides on will be unknown, so the motion of the part in response to a push cannot be predicted exactly. Using a simple variational principle (which is derived), we find the set of possible motions of a part for a given push, for all collections of points of contact. The answer emerges as a locus of centers of rotation (CORs). Manipulation plans made using this locus will succeed despite unknown details of contact. Results of experimental tests of the COR loci are presented. Uncertainty in the initial configuration of a part is usually also present. To plan in the presence of uncertainty, configuration maps are defined, which map all configurations of a part before an elementary operation to all possible outcomes, thus encapsulating the physics and geometry of the operation. The configuration map for an operation sequence is a product of configuration maps of elementary operations. Using COR loci we compute configuration maps for elementary sliding operations. Appropriate search techniques are applied to find operation sequences which succeed in the presence of uncertainty in the initial configuration and unknown details of contact. Such operation sequences may be used as parts feeder designs or as manipulation or grasping strategies for robots. As an example we demonstrate the automated design of a class of passive parts feeders consisting of multiple sequential fences across a conveyor

    Levey, Janet A

    The purpose of the study was to examine the characteristics and relationships of nurse educators' teaching practices, knowledge, support, and willingness to adopt inclusive teaching strategies (WillAdITS). Adopting more inclusive teaching strategies based on universal design for instruction is an innovative way for educators to reach today's diverse student body. However, the pedagogy has not diffused into nursing education. Descriptive statistics and hierarchical multiple regression were used for analyzing data from 311 nurse educators in prelicensure and RN to BSN programs. The model explained 44.8 percent of the variance in WillAdITS. The best indicators for this pedagogy were knowledge of universal design for instruction, social system support for inclusive teaching strategies, multiple instructional formats, and years of teaching. Knowing factors influencing the adoption of inclusive teaching strategies can inform schools of nursing of areas needing further development in the preparation of novice to experienced educators to teach diverse learners.

    2004-04-01

    This study had the objective to report the experience of using pedagogic psychodrama as a teaching and learning strategy about the worker's health. It was developed with 18 students from the Master Program from the School of Nursing of the University of São Paulo at Ribeirão Preto, during the second semester of 2002. Interactive, dynamic and interpersonal activities, and role playing were initially conducted looking for students and educator's spontaneity. Moreno's psychodramatic theory was the theoretical framework used. Creativity, logical reasoning, involvement with learning, and organization of concepts using their own living experience were observed, contributing to the experience as a whole. Therefore, the experiment was considered successful.

    Full Text Available The current conditions of the classroom learning tend to be a one-way process based in teacher exposition, this make a negative impact on learning make it a mechanical and not meaningful activity. One possibility to improve the quality of teaching is to innovate methodologies and varying forms of presenting information to students, such as the use of technology in the teaching process. The Interactive Whiteboard (IBW is one of the technologies that are being implemented in Brazilian schools. One of the promising possibilities to add value to the use of LDI in classroom are "learning objects" (LO. However, one problem is that often the LO are not fully suited to the dynamics of IWB, whether functional or pedagogical point of view. The objective of this study is to analyze and propose a set of indicators that evaluate the learning objects for use in conjunction with Interactive Whiteboards. The selection and definition of evaluation indicators was carried from the literature review on the subject and based on LDI experiences of use in Municipal Elementary School. After defining the set of indicators was conducted a evaluation of a sample of 30 OA utilized to teaching mathematics in 3rd grade of elementary school. The results of the evaluation indicate that the proposed indicators are suitable for a pre-analysis of OA and assisting in the process of selection of these.

    Full Text Available English is getting more crucial to be mastered since its important part in the world nowadays.  It is not only as a means of communication but also a means transferring knowledge, news, and technology around the world. There are four basic skills in English such as listening, speaking, reading, and writing, every students must have problem in learning and mastering those skill. But writing is the main issue to be discussed in this article.  In writing, some of the writer’s students feel difficult to determine the topic when they want to write, they are hardly to complete a writing paper because they run out of idea. In this case the students need to absorb some information to understand a word, including how to combine a word with the other words. Therefore the teacher should have a strategy to get the students understanding and overcome their problems.Teaching is about just how to encourage the learners to achieve their goals and other times it requires that we actually facilitate resources and foster experiences so students can learn, continue learning and love the process. It is an art of the teacher to know how to make the students able to create knowledge of their own. Brainstorming is one of the teaching techniques in writing that can encourage the students to think about the topic as many as possible. This technique is help the students to enrich their vocabularies then create an idea become a writing composition. By using this strategy the students will be able to improve their writing skill. Brainwriting is an alternative method to brainstorming that tries to encourage a more uniform participation within a group. Like brainstorming, it is designed to generate lots and lots of ideas in a short amount of time.

    One of our roles as nurse educators is to teach best practices related to patient care. However, have you ever stopped to think about what evidence supports your teaching strategies? Just as our patients deserve care that is based on the best available evidence, our learners also deserve education that is based on evidence.1-3 With so many advances in knowledge, technology, and even life itself, it is interesting that education has changed very little over the past 100 years. A study among 946 nurse educators documented that most teach the way they were taught.4 In addition, even after learning new strategies, educators often continue teaching in the manner they are most comfortable. However, this trend is beginning to change. Nurse educators are becoming increasingly aware of and willing to try new and innovative teaching strategies. Educators are also seeking out evidence-based teaching strategies and are becoming more involved in nursing education research.

    Full Text Available The heterogeneous nature of the Chinese classroom is a reality in the teaching of Chinese in France, both in secondary and higher education. This heterogeneity is due to several reasons: different levels of language knowledge, different origins and backgrounds of the students, different teaching/learning objectives, different cultural and family background, and social factors. Our research has been conducted in  a final-year LIE college class (langue inter-établissement; in a French secondary school. In our study, the following questions have been posed: How to best adapt the teaching of Chinese to fit the needs of all students? Would differentiated instruction be a solution? What would be the best strategies and practices, in view of the CEFR requirements related to teaching content, to tasks and to assessment? Taking into account a detailed analysis of the class in question in terms of the type of students, the differences in their knowledge of language, and their learning goals, , we adopt  the theory of differentiated instruction –  its main ideas strategies, its overall methodology and practical techniques to address the difficulties ensuing from classroom heterogeneity. The differentiation is implemented at the level of content, task selection, course structure and evaluation. Are there any limitations to differentiated instruction? Strong discrepancies in the levels of students’ knowledge is potentially a problem, and differences in their work pace as well as the teachers’ increased workload can also present difficulties. New ways of organizing language classes such as grouping students on the basis of their various language skills could help solve these issues.

  18. Effective teaching and feedback strategies in the or and beyond.

    2013-12-01

    Maintaining a standard of excellence for graduating surgical residents requires a comprehensive and consistent approach to surgical education. The omnipresent and increasing barriers to education must also be recognized and addressed. The implementation of effective teaching strategies is largely dependent on the resources available at each institution and the vision of education. Unfortunately, allocating time for surgeons to teach both inside and outside the operating room has become a foreign concept to administration. Furthermore, the reduction in case numbers performed by trainees now demands "quality over quantity" to ensure success. Quality teaching moments will only be realized when emphasis is placed on preparation, useful instruction during the procedure, and postoperative feedback. Ideal preparation entails a detailed discussion between the trainee and surgeon about the specific learning goals for the case. During the procedure, the faculty surgeon must strive to maximize the experience through effective communication while performing an efficient and safe operation. Numerous validated objective assessment tools exist for postprocedure evaluation but are grossly underutilized. Surgical education must thoughtfully be approached with the same fervor and detail as patient care. As faculty, it is our responsibility to train the next generation of surgeons and therefore "every case must count."

  1. Object similarity affects the perceptual strategy underlying invariant visual object recognition in rats

    Directory of Open Access Journals (Sweden)

    Federica Bianca Rosselli

    2015-03-01

    Full Text Available In recent years, a number of studies have explored the possible use of rats as models of high-level visual functions. One central question at the root of such an investigation is to understand whether rat object vision relies on the processing of visual shape features or, rather, on lower-order image properties (e.g., overall brightness. In a recent study, we have shown that rats are capable of extracting multiple features of an object that are diagnostic of its identity, at least when those features are, structure-wise, distinct enough to be parsed by the rat visual system. In the present study, we have assessed the impact of object structure on rat perceptual strategy. We trained rats to discriminate between two structurally similar objects, and compared their recognition strategies with those reported in our previous study. We found that, under conditions of lower stimulus discriminability, rat visual discrimination strategy becomes more view-dependent and subject-dependent. Rats were still able to recognize the target objects, in a way that was largely tolerant (i.e., invariant to object transformation; however, the larger structural and pixel-wise similarity affected the way objects were processed. Compared to the findings of our previous study, the patterns of diagnostic features were: i smaller and more scattered; ii only partially preserved across object views; and iii only partially reproducible across rats. On the other hand, rats were still found to adopt a multi-featural processing strategy and to make use of part of the optimal discriminatory information afforded by the two objects. Our findings suggest that, as in humans, rat invariant recognition can flexibly rely on either view-invariant representations of distinctive object features or view-specific object representations, acquired through learning.

  2. AHP-ENHANCED SWOT MATRIX TEACHING STRATEGY

    Full Text Available ABSTRACT The SWOT matrix is the quintessential analysis tool for business purposes, and is taught both in undergraduate and postgraduate courses. However, it is widely understood that the selection of the critical success factors (CSFs that are included for analysis in the matrix is a very subjective and unstructured process, leaving room for bias and arbitrariness. One way to give a better foundation and support to the analysis results is by utilizing Analytic Hierarchical Process (AHP in order to weigh the importance of CSFs in the SWOT matrix and increase reliability of the output. This paper contains the design of a strategy to teach this topic in a marketing planning course, with the addition of a useful technique to overcome the limitations of the tool. RESUMEN La matriz FODA es la herramienta de análisis por excelencia para fines de negocios, y se enseña en cursos de pregrado y postgrado. Sin embargo, se entiende que la elección de los factores críticos de éxito (FCEs que se incluyen en la matriz para el análisis es un proceso muy subjetivo y no estructurado, que da cabida a sesgos y arbitrariedad. Una forma de dar una mejor base y respaldo a los resultados del análisis es mediante la utilización del Proceso Jerárquico Analítico (AHP con el fin de ponderar la importancia de los FCEs en la matriz FODA y aumentar la fiabilidad de los resultados. Este documento contiene el diseño de una estrategia para enseñar este tema en un curso de planificación de marketing, con la adición de una técnica útil para superar las limitaciones de la herramienta.

  12. Mitigation strategies for pandemic influenza A: balancing conflicting policy objectives.

    Directory of Open Access Journals (Sweden)

    T Déirdre Hollingsworth

    Full Text Available Mitigation of a severe influenza pandemic can be achieved using a range of interventions to reduce transmission. Interventions can reduce the impact of an outbreak and buy time until vaccines are developed, but they may have high social and economic costs. The non-linear effect on the epidemic dynamics means that suitable strategies crucially depend on the precise aim of the intervention. National pandemic influenza plans rarely contain clear statements of policy objectives or prioritization of potentially conflicting aims, such as minimizing mortality (depending on the severity of a pandemic or peak prevalence or limiting the socio-economic burden of contact-reducing interventions. We use epidemiological models of influenza A to investigate how contact-reducing interventions and availability of antiviral drugs or pre-pandemic vaccines contribute to achieving particular policy objectives. Our analyses show that the ideal strategy depends on the aim of an intervention and that the achievement of one policy objective may preclude success with others, e.g., constraining peak demand for public health resources may lengthen the duration of the epidemic and hence its economic and social impact. Constraining total case numbers can be achieved by a range of strategies, whereas strategies which additionally constrain peak demand for services require a more sophisticated intervention. If, for example, there are multiple objectives which must be achieved prior to the availability of a pandemic vaccine (i.e., a time-limited intervention, our analysis shows that interventions should be implemented several weeks into the epidemic, not at the very start. This observation is shown to be robust across a range of constraints and for uncertainty in estimates of both R(0 and the timing of vaccine availability. These analyses highlight the need for more precise statements of policy objectives and their assumed consequences when planning and implementing strategies

    In order for teaching to be successful, students need to be actively involved in learning. However, research on teaching effectiveness often neglects students' learning activities. Although it is assumed that effective teaching promotes the use of beneficial learning activities, empirical evidence for this connection is still limited. This study aimed to investigate the connection between effective teaching and reported learning activities. We hypothesize specific relations between a three-dimensional model of teaching quality (i.e., cognitive activation, supportive climate, and classroom management) and students' reported use of metacognitive strategies. Students' intrinsic motivation is considered as a mediator and a moderator of this connection. N = 1,052 students from 53 German primary school classes and their science teachers participated. Data were collected through classroom or video observation and questionnaires over a period of approximately 2 months. Multilevel analysis was utilized to test our hypotheses. Each dimension of teaching quality positively predicted students' reported use of metacognitive strategies. For supportive climate, this connection was mediated by students' intrinsic motivation. Cognitive activation negatively predicted the slopes between students' reported metacognitive strategy use and motivation. The results support the notion that effective teaching is connected to learning activities and stress the importance of students' learning motivation. Results from the cross-level interaction could indicate that especially less motivated students' reported metacognitive strategy use might be supported by cognitively activating teaching. © 2016 The British Psychological Society.

  4. Why Inquiry? Primary Teachers' Objectives in Choosing Inquiry- and Context-Based Instructional Strategies to Stimulate Students' Science Learning

    Science.gov (United States)

    Walan, Susanne; Nilsson, Pernilla; Ewen, Birgitta Mc

    2017-10-01

    Studies have shown that there is a need for pedagogical content knowledge among science teachers. This study investigates two primary teachers and their objectives in choosing inquiry- and context-based instructional strategies as well as the relation between the choice of instructional strategies and the teachers' knowledge about of students' understanding and intended learning outcomes. Content representations created by the teachers and students' experiences of the enacted teaching served as foundations for the teachers' reflections during interviews. Data from the interviews were analyzed in terms of the intended, enacted, and experienced purposes of the teaching and, finally, as the relation between intended, enacted, and experienced purposes. Students' experiences of the teaching were captured through a questionnaire, which was analyzed inductively, using content analysis. The results show that the teachers' intended teaching objectives were that students would learn about water. During the enacted teaching, it seemed as if the inquiry process was in focus and this was also how many of the students experienced the objectives of the activities. There was a gap between the intended and experienced objectives. Hardly any relation was found between the teachers' choice of instructional strategies and their knowledge about students' understanding, with the exception that the teacher who also added drama wanted to support her students' understanding of the states of water.

    Full Text Available Because of the large impact that today computer networks, their study in related fields such as Telecommunications Engineering and Electronics is presented to the student with great appeal. However, by digging in content, lacking a strong practical component, you can make this interest decreases considerably. This paper proposes the use of teaching strategies and analogies, media and interactive applications that enhance the teaching of discipline networks and encourage their study. It is part of an analysis of how the teaching of the discipline process is performed and then a description of each of these strategies is done with their respective contribution to student learning.

    As a nurse educator, I encountered many complaints from staff nurses about mandatory inservice education programs, stating that they are repetitious, time-consuming, often too basic, and at times, downright boring. One exception was an Infection Control Week education session that was done in the form of a game. This session set attendance records and had very positive feedback from staff nurses. As a result of this feedback, the use of gaming as a teaching strategy in nursing education was explored. A review of the literature on gaming as a teaching strategy was conducted with special attention to its history, current use, and successes in nursing education. Introduced as a formal teaching strategy more than 75 years ago, gaming offers many advantages over more traditional teaching methods. Games connect theory more closely to real life situation and add innovation, diversity, and the opportunity for immediate feedback. Although gaining in popularity, gaming is not extensively used in nursing education as it is not considered a serious educational tool. However, recent literature suggests much success with its use. Gaming as a teaching strategy has proven to be an effective way of conveying information in a stimulating, appealing manner. Games facilitate both beginning and experienced nurses' learning by providing an opportunity for experience without the danger or fear of jeopardizing patient safety.

    1994-12-01

    A strategy is presented for implementation of the Data Quality Objectives (DQO) process to the Spent Nuclear Fuels Project (SNFP) characterization activities. Westinghouse Hanford Company (WHC) and the Pacific Northwest Laboratory (PNL) are teaming in the characterization of the SNF on the Hanford Site and are committed to the DQO process outlined in this strategy. The SNFP characterization activities will collect and evaluate the required data to support project initiatives and decisions related to interim safe storage and the path forward for disposal. The DQO process is the basis for the activity specific SNF characterization requirements, termed the SNF Characterization DQO for that specific activity, which will be issued by the WHC or PNL organization responsible for the specific activity. The Characterization Plan prepared by PNL defines safety, remediation, and disposal issues. The ongoing Defense Nuclear Facility Safety Board (DNFSB) requirement and plans and the fuel storage and disposition options studies provide the need and direction for the activity specific DQO process. The hierarchy of characterization and DQO related documentation requirements is presented in this strategy. The management of the DQO process and the means of documenting the DQO process are described as well as the tailoring of the DQO process to the specific need of the SNFP characterization activities. This strategy will assure stakeholder and project management that the proper data was collected and evaluated to support programmatic decisions

    Radiology expertise is dependent on the use of efficient search strategies. The aim of this study is to investigate the effect of teaching search strategies on trainee's accuracy in detecting lung nodules at computed tomography. Two search strategies, "scanning" and "drilling," were tested with a randomized crossover design. Nineteen junior radiology residents were randomized into two groups. Both groups first completed a baseline lung nodule detection test allowing a free search strategy, followed by a test after scanning instruction and drilling instruction or vice versa. True positive (TP) and false positive (FP) scores and scroll behavior were registered. A mixed-design analysis of variance was applied to compare the three search conditions. Search strategy instruction had a significant effect on scroll behavior, F(1.3) = 54.2, P search (M = 15.3, SD = 4.6), t(18) = 4.44, P search. FP scores for drilling (M = 7.3, SD = 5.6) were significantly lower than for free search (M = 12.5, SD = 7.8), t(18) = 4.86, P < 0.001. Teaching a drilling strategy is preferable to teaching a scanning strategy for finding lung nodules. Copyright © 2017 The Association of University Radiologists. Published by Elsevier Inc.

    Full Text Available INTRODUCTION: Biotechnology is a new bachelor degree in UFPA, and has been stablished with excellency in the state of Pará. However, there is the need to promote comprehension and learning in Biochemistry, as well as interdisciplinarity, that is an essential part of biotechnology. OBJECTIVES:  To increase learning and interdisciplinarity, educational games were used as tools. The students were instigated to develop educational games in different topics of energy metabolism. MATERIALS AND METHODS: The games were developed to be used in any teaching environment, since they were made with low-cost and accessible materials. This strategy was applied in three semesters in different Biochemistry classes, between 2012 and 2014. The best games in each class were used in following semesters. DISCUSSION AND RESULTS: Since the first semester, the failing rates dropped 15% compared to the previous semester, in which educational games were not used. An increase in learning (by observation could be noticed, including comprehension of metabolic pathways and their conections. Twenty games were developed in three semesters, and four of them are still being improved and used in other classes. The participant students answered a questionnaire, in which 47% defined the games as “Relaxing and Instigating”, 33% said the games “Accomplished their didactic and educational role” and 54% said they would recommend the use of these games as a reviewing activity. At the moment, another approach is being used to teach Biochemistry – Gamification, which uses elements found in games, as conflict, cooperation, rules and fun, to improve students’ motivation and engagement. CONCLUSION: As a partial result, there was greater in-class interest and engagement, better comprehension of the course content and the activities gave the students the opportunity to work in groups, to think critically about the themes and to develop opinions based on interdisciplinar and formal

    Full Text Available Sovereign Wealth Funds (SWFs have steadily increased their importance in the global financial system in the last decade and especially during the financial crisis period. Although the objectives and investment strategies of SWFs are quite diverse, I propose to sort them into three main groups, depending on their sponsor countries’ endowment with resources and investment objectives. I present case studies and empirical analyses that reflect SWF investment activities and try to elaborate on the special role of each SWF group. Special emphasis is given to the recent financial crisis, where SWFs also acted as bailout investors by injecting substantial capital into global financial institutions, filling a financing gap that other institutional investors could not close

    Full Text Available Th is article is based on Chapter 5 of my book Media and Digital Literacies in Secondary School (2013. The chapter has been shortened and rewritten in some parts for the article. The article focuses on different classroom strategies identified during the ethnographic school research in one of the Finnish secondary schools carried out during the academic year 2009–2010. The study indicates that teachers analyse and produce media texts as key strategies in media education. In the article, I will give examples of an advertisement project, a soap opera drama, an animation project, a "life career assignment" and a newspaper strategy in different learning settings. All examples indicate that media education needs to build a strong bridge between youth and school culture and that technology in the school follows the content of learning.

    2012-12-01

    The objective of this research focuses on the framework of teaching strategies, by acknowledging learning styles as first determination and, in relation to the changes that these are going through, identifying the teaching strategies best rated and preferred by the students. This is a prospective open cohort study with the students of Nursing Diploma 2007/2010 of the Universidad de Córdoba. Once the population was identified in the first year (first analysis), annual measurings were undertaken every year during their training. In order to study the learning styles, the questionnaire CHAEA was administered and a scale from 1 to 10 (1 = highest, 10 = lowest) was used to determine the preferences for learning strategies. The results show the variability of the learner (up to 11 styles). However, the dominant style is the reflective, followed by the theoretical and the pragmatic. The least developed was the active style. As the years of training go by, a tendency towards a dual style (reflective-theoretical) can be observed. In relation to teaching strategies, the preferred ones were those set in professional areas, workshops and debates. Relevant changes were also seen as they advanced in their training. The results establish a specific significant relationship between learning styles and teaching strategies.

    Physicians will be called upon to care for patients who bear the burden of disease from the impact of climate change and ecologically irresponsible practices which harm ecosystems and contribute to climate change. However, physicians must recognize the connection between the climate, ecosystems, sustainability, and health and their responsibility and capacity in changing the status quo. Sustainable healthcare education (SHE), defined as education about the impact of climate change and ecosystem alterations on health and the impact of the healthcare industry on the aforementioned, is vital to prevention of adverse health outcomes due to the changing climate and environment. To systematically determine which and when a set of SHE objectives should be included in the medical education continuum. Fifty-two SHE experts participated in a two-part modified-Delphi study. A survey was developed based on 21 SHE objectives. Respondents rated the importance of each objective and when each objective should be taught. Descriptive statistics and an item-level content validity index (CVI) were used to analyze data. Fifteen of the objectives achieved a content validity index of 78% or greater. The remaining objectives had content validity indices between 58% and 77%. The preclinical years of medical school were rated as the optimal time for introducing 13 and the clinical years for introducing six of the objectives. Respondents noted the definition of environmental sustainability should be learned prior to medical school and identifying ways to improve the environmental sustainability of health systems in post-graduate training. This study proposes SHE objectives for the continuum of medical education. These objectives ensure the identity of the physician includes the requisite awareness and competence to care for patients who experience the impact of climate and environment on health and advocate for sustainability of the health systems in which they work.

    Altair Alberto Fávero

    2013-06-01

    Full Text Available The continuing education of teachers has become a compulsory subject in our time. There is a consensus among teachers and school leaders regarding the need to “educate the educators”, because the rational knowledge learned in the process of formation of teachers is not sufficient to face the complexity and the diversity of the problems that the teachers’ work demands. It is necessary and urgent, in any area from education, to reflect about the new forms of exercising the skills needed for the professional practice. In regards to teaching, reflecting in and about the practice enables the educator to reconsider their own performance. The focus of this essay is to analyze the continuing education of teachers from the paradigm of the reflective teacher.KEYWORDS: Reflective teacher, Formative process, Educational policies.

  16. Using modern teaching strategies to teach upper abdominal sonography to medical students.

    Cheng, Wei-Chun; Lin, Xi-Zhang; Chen, Chiung-Yu

    2013-07-01

    Upper abdominal sonography can help physicians to confirm the diagnosis of various hepatobiliary diseases. Teaching sonography skills to medical students is important because it may enhance their level of knowledge and overall development during their gastroenterology section rotation. Sonographic imaging is abstract and students can be easily confused when scanning the abdominal structures from different sites and directions. We used several modern teaching strategies to facilitate the learning of sonography skills. The year five medical students beginning a gastroenterology section rotation for their first-year clerkship were taught abdominal sonography skills. Abstract sonographic images were related to concrete objects and the surrounding structures were further indicated. Each of the images was given a specific name and was sorted according to the scanning site. A mnemonics system was designed to help students to memorize the names of these images. A badge was created to recognize the achievement of being able to complete a basic upper abdominal sonography. Students were free (i.e., not obligated) to request a demonstration opportunity to show their skills within 2 weeks after receiving tutelage. We recorded the number of students who received training and were able to successfully complete the task; these individuals then received a badge to be pinned onto their white coats. Sixty-three of 68 students (92.6%) requested evaluation and all of them passed. We have greatly simplified the process of learning about upper abdominal sonography by using andragogy to enhance learning, mnemonics to help memory, and a pin-badge reward system to stimulate incentives.

    2005-01-01

    This paper will summarize the objectives, strategies, and key chemical separation challenges for the Advanced Fuel Cycle Initiative (AFCI). The major objectives are as follows: Waste management--defer the need for a second geologic repository for a century or more, Proliferation resistance--be more resistant than the existing PUREX separation technology or uranium enrichment, Energy sustainability--turn waste management liabilities into energy source assets to ensure that uranium ore resources do not become a constraint on nuclear power, and Systematic, safe, and economic management of the entire fuel cycle. There are four major strategies for the disposal of civilian spent fuel: Once-through--direct disposal of all discharged nuclear fuel, Limited recycle--recycle transuranic elements once and then direct disposal, Continuous recycle--recycle transuranic elements repeatedly, and Sustained recycle--same as continuous except previously discarded depleted uranium is also recycled. The key chemical separation challenges stem from the fact that the components of spent nuclear fuel vary greatly in their influence on achieving program objectives. Most options separate uranium to reduce the weight and volume of waste and the number and cost of waste packages that require geologic disposal. Separated uranium can also be used as reactor fuel. Most options provide means to recycle transuranic (TRU) elements--plutonium (Pu), neptunium (Np), americium (Am), curium (Cm). Plutonium must be recycled to obtain repository, proliferation, and energy recovery benefits. U.S. non-proliferation policy forbids separation of plutonium by itself; therefore, one or more of the other transuranic elements must be kept with the plutonium; neptunium is considered the easiest option. Recycling neptunium also provides repository benefits. Americium recycling is also required to obtain repository benefits. At the present time, curium recycle provides relatively little benefit; indeed, recycling

    2014-06-01

    Technology has changed healthcare institutions into automated settings with the potential to greatly enhance the quality of healthcare. Implementation of electronic health records (EHRs) to replace paper charting is one example of the influence of technology on healthcare worldwide. In the past decade nursing higher education has attempted to keep pace with technological changes by integrating EHRs into learning experiences. Little is known about educators' teaching beliefs and the use of EHRs as a teaching strategy. This study explores the composition of core teaching beliefs of nurse educators and their related teaching practices within the context of teaching with EHRs in the classroom. A collective case study and qualitative research approach was used to explore and describe teaching beliefs of seven nurse educators teaching with EHRs. Data collection included open-ended, audio-taped interviews and non-participant observation. Content analysis of transcribed interviews and observational field notes focused on identification of teaching belief themes and associated practices. Two contrasting collective case studies of teaching beliefs emerged. Constructivist beliefs were dominant, focused on experiential, student-centered, contextual and collaborative learning, and associated with expanded and a futuristic view of EHRs use. Objectivist beliefs focused on educators' control of the context of learning and were associated with a constrained, limited view of EHRs. Constructivist educators embrace technological change, an essential ingredient of educational reform. We encourage nurse educators to adopt a constructivist view to using technology in teaching in order to prepare nurses for a rapidly changing, technologically sophisticated practice.

  1. Teaching object concepts for XML-based representations.

    Energy Technology Data Exchange (ETDEWEB)

    Kelsey, R. L. (Robert L.)

    2002-01-01

    Students learned about object-oriented design concepts and knowledge representation through the use of a set of toy blocks. The blocks represented a limited and focused domain of knowledge and one that was physical and tangible. The blocks helped the students to better visualize, communicate, and understand the domain of knowledge as well as how to perform object decomposition. The blocks were further abstracted to an engineering design kit for water park design. This helped the students to work on techniques for abstraction and conceptualization. It also led the project from tangible exercises into software and programming exercises. Students employed XML to create object-based knowledge representations and Java to use the represented knowledge. The students developed and implemented software allowing a lay user to design and create their own water slide and then to take a simulated ride on their slide.

  2. Creative payment strategy helps ensure a future for teaching hospitals.

    Vancil, D R; Shroyer, A L

    1998-11-01

    The Colorado Medicaid Program in years past relied on disproportionate share hospital (DSH) payment programs to increase access to hospital care for Colorado citizens, ensure the future financial viability of key safety-net hospitals, and partially offset the state's cost of funding the Medicaid program. The options to finance Medicaid care using DSH payments, however, recently have been severely limited by legislative and regulatory changes. Between 1991 and 1997, a creative Medicaid refinancing strategy called the major teaching hospital (MTH) payment program enabled $131 million in net payments to be distributed to the two major teaching hospitals in Colorado to provide enhanced funding related to their teaching programs and to address the ever-expanding healthcare needs of their low-income patients. This new Medicaid payment mechanism brought the state $69.5 million in Federal funding that otherwise would not have been received.

    Matrix strategies employing parts of speech arranged in systematic language matrices and milieu language teaching strategies have been successfully used to teach word combining skills to children who have cognitive disabilities and some functional speech. The present study investigated the acquisition and generalized production of two-term semantic relationships in a new population using new types of symbols. Three children with cognitive disabilities and little or no functional speech were taught to combine graphic symbols. The matrix strategy and the mand-model procedure were used concomitantly as intervention procedures. A multiple probe design across sets of action-object combinations with generalization probes of untrained combinations was used to teach the production of graphic symbol combinations. Results indicated that two of the three children learned the early syntactic-semantic rule of combining action-object symbols and demonstrated generalization to untrained action-object combinations and generalization across trainers. The results and future directions for research are discussed.

    2006-09-01

    Full Text Available Changes in nursing education involve the move from traditional teaching approaches that are teacher-centred to facilitation, a student centred approach. The studentcentred approach is based on a philosophy of teaching and learning that puts the learner on centre-stage. The aim of this study was to identify the challenges of facilitators of learning using facilitation as a teaching method and recommend strategies for their (facilitators development and support. A qualitative, explorative and contextual design was used. Four (4 universities in South Africa which utilize facilitation as a teaching/ learning process were identified and the facilitators were selected to be the sample of the study. The main question posed during in-depth group interviews was: How do you experience facilitation as a teaching/learning method?. Facilitators indicated different experiences and emotions when they first had to facilitate learning. All of them indicated that it was difficult to facilitate at the beginning as they were trained to lecture and that no format for facilitation was available. They experienced frustrations and anxieties as a result. The lack of knowledge of facilitation instilled fear in them. However they indicated that facilitation had many benefits for them and for the students. Amongst the ones mentioned were personal and professional growth. Challenges mentioned were the fear that they waste time and that they do not cover the content. It is therefore important that facilitation be included in the training of nurse educators.

  9. Objectivity

    Daston, Lorraine

    2010-01-01

    Objectivity has a history, and it is full of surprises. In Objectivity, Lorraine Daston and Peter Galison chart the emergence of objectivity in the mid-nineteenth-century sciences--and show how the concept differs from its alternatives, truth-to-nature and trained judgment. This is a story of lofty epistemic ideals fused with workaday practices in the making of scientific images. From the eighteenth through the early twenty-first centuries, the images that reveal the deepest commitments of the empirical sciences--from anatomy to crystallography--are those featured in scientific atlases, the compendia that teach practitioners what is worth looking at and how to look at it. Galison and Daston use atlas images to uncover a hidden history of scientific objectivity and its rivals. Whether an atlas maker idealizes an image to capture the essentials in the name of truth-to-nature or refuses to erase even the most incidental detail in the name of objectivity or highlights patterns in the name of trained judgment is a...

    2010-05-01

    Full Text Available It is well known that students and teachers have difficulties in learning and teaching Biochemistry due to its abstract and interconnected contents. This work proposes a didactic strategy in order to facilitate teaching and learning process in Biochemistry. The strategy was implemented with biological science undergraduate students. At first, the students were divided into groups with a specific topic to develop a game. During the semester, problem based learning cases, online activities like crossword puzzle, essay questions and educational softwares were used to present the content of each topic. The groups were oriented in classroom and online, to choose and organize contents and create ways to approach them in games. At the end of the course the groups played each other games, which were evaluated by teacher and students following some criteria like: creativity, content organization, interdisciplinarity, proposal coherence, instructions clarity, specific content. The game elaboration contributed to the development of social and cognitive functions, such as teamwork and troubleshooting, providing an interesting perspective to the student about knowledge construction process. The strategy showed up students' creativity and ability to reorganize their knowledge to a different education level. In an overview, the results indicate that the proposed didactic strategy is an effective way to enhance learning and to motivate students into Biochemistry topics.

    Alamri, Aziz S.

    Scientific developments such as cloning and nuclear energy have generated many controversial issues pertain to many political, social, environmental, ethical and cultural values in different societies around the globe. These controversies delimited and encircled the potential of including and teaching some important aspects of science in schools and therefore caused less consideration to the influence of these issues on enhancing the scientific literacy of people in general. The purpose of this study was to investigate how Saudi science teachers in the city of Tabuk in Saudi Arabia view and teach SSI in Saudi Arabia. This study employed semi-structured interviews with Saudi science teachers. Methodologically, this study used a constructivist grounded theory as a method for analysis to generate in-depth descriptive data about Saudi science teachers' views and teaching strategies of socio-scientific issues. Some direct and indirect benefits pertain to teaching science, understanding the relationship between science, religion, and society and some other topics are discussed in this study.

    2013-12-01

    Full Text Available The lack of discussions that clarify the teaching of alternative and complementary therapies in undergraduate nursing programs shows the need for developing research on this topic. The objective of this study was to identify, in scientific literature, the strategies for teaching alternative and complementary therapies in nursing undergraduate programs. The guiding methodology used was integrative review. The search was performed on SCIENCE DIRECT, LILACS and MEDLINE databases. According to the articles included in this study, the proposals for including these therapies in the program are by: lectures, theoretical courses and discussion groups. However, studies should be conducted to confirm the efficacy of these strategies so these therapeutic methods can be included in the Pedagogical Political Project of the nursing undergraduate program, thus allowing for the consolidation of those practices.

  19. Cognitive conflict as a teaching strategy in solving chemistry problems: A dialectic-constructivist perspective

    Science.gov (United States)

    Niaz, Mansoor

    The main objective of this study was to evaluate the effect of teaching experiments within a dialectic-constructivist framework based on the following considerations: (a) Cognitive conflicts used in the teaching experiments must be based on problem-solving strategies that students find relatively convincing: (b) after having generated a cognitive conflict, it is essential that the students be provided with an experience that could facilitate the resolution of the conflict; and (c) the teaching strategy developed is used by an interactive constructivist approach within an intact classroom. The study was based on two sections of freshman students who had registered for Chemistry I at the Universidad de Oriente, Venezuela. One of the sections was randomly designated as the control group and the other as the experimental group. To introduce cognitive conflict, the experimental group was exposed to two teaching experiments dealing with stoichiometry problems based on the concept of limiting reagent. Students in the control group were exposed to the same problems - however, without the cognitive conflict teaching experiments format. To evaluate the effect of the teaching experiments, both groups were evaluated on five different problems at different intervals during the semester, referred to as posttests. All posttests formed part of the regular evaluation of the students. Results obtained show the advantage of the experimental group on four of the posttests. It is concluded that the experimental treatment was effective in improving performance on the immediate posttests. It was observed that some students protect their core belief [see Lakatos, I. (1970). Falsification and the methodology of scientific research programmes. In I. Lakatos & A. Musgrave (Eds.), Criticism and the growth of knowledge (pp. 91-196). Cambridge: Cambridge University Press] in stoichiometry (establishing equivalent relations between different elements or compounds) by ignoring the conflicting

    Full Text Available Within this paper, we are focusing on the relationships between teaching strategies, learning styles, and the students’ academic achievement in higher education. The main objective of this study is to compare three groups of pre-service teachers having different majors (i.e., Educational Sciences, Economic Sciences, and Foreign Languages in order to identify the potential differences in their academic achievement. More precisely, we attempt to highlight the categories of teaching strategies that lead to the best academic achievement for students having the same learning style, and different fields of study. A sample of 269 pre-service teachers from three faculties belonging to Transilvania University of Braşov participated in the study. The data was collected through a survey method and the one-way analysis of variance was used to determine the differences among the groups. Significant differences among the three categories of students with different majors occurred in relation with the most effective teaching strategies corresponding to each learning style category.

    Full Text Available Monitoring and evaluating staff tutors necessitates constant follow-up to ensure that they are in line with the University’s mission and vision. This has raised a fundamental educational question: how to coach rather than monitor the tutors. To answer this question, Cottrell’s (2008 CREAM (Creative, Reflective, Effective, Active, Motivated strategy was applied to coach these tutors following the GROW Model (Goal, Reality, Options, Will way forward as a framework for structuring both team and individual coaching sessions. Cottrell’s strategy was initially developed for enhancing the learner’s self-directed/autonomous learning. For the purpose of this implementation, the researchers applied the CREAM strategy as a self-assessment and observation tool. Being pragmatic leaders, they conducted three team coaching sessions and one-to-one individual sessions throughout the academic semester following the GROW Model to: establish SMART Goals, examine the current Reality, explore possible Options/Obstacles, and establish the Will. A checklist was developed to measure the staff tutors’ self-assessment of their Creative, Reflective, Effective, Active, and Motivated teaching practices and the same checklist was used by the head of the program as an observation checklist to evaluate these practices. The two tools were statistically analysed and a correlation was found.

    2016-01-01

    Cultural competence and cultural humility are ongoing processes that healthcare professionals should continually strive for in order to provide effective and comprehensive plans of care for patients. This 2-year, longitudinal, educational pilot study describes the levels of competency in second-year entry-level physical therapy students and compares the outcomes of three teaching strategies for cultural competence and cultural humility. All students received a standard 2-hour lecture; study volunteers were randomly assigned to one of two enriched educational groups, involving a standardized patient or a paper case enrichment. Students shifted from initial levels of "culturally incompetent" and/or "culturally aware" to "culturally competent" as measured by the Inventory for Assessing the Process of Cultural Competence Among Healthcare Professionals-Revised. This shift was maintained after 1.5 yrs following the exposure. Because the enriched educational groups were underpowered, preliminary quantitative data are inconclusive, but qualitative feedback from students is strongly positive. A minimal dose of a structured 2-hr lecture with a skilled instructor, who creates a safe environment for cultural learning, produced positive shifts toward greater cultural competence. Five processes emerged for teaching cultural humility that may assist in designing comprehensive educational experiences on this topic. A framework for organizing course content is presented.

    2011-08-01

    Physicians need good communication skills to communicate effectively with patients. The objective of this review was to identify effective training strategies for teaching communication skills to qualified physicians. PubMED, PsycINFO, CINAHL, and COCHRANE were searched in October 2008 and in March 2009. Two authors independently selected relevant reviews and assessed their methodological quality with AMSTAR. Summary tables were constructed for data-synthesis, and results were linked to outcome measures. As a result, conclusions about the effectiveness of communication skills training strategies for physicians could be drawn. Twelve systematic reviews on communication skills training programmes for physicians were identified. Some focused on specific training strategies, whereas others emphasized a more general approach with mixed strategies. Training programmes were effective if they lasted for at least one day, were learner-centred, and focused on practising skills. The best training strategies within the programmes included role-play, feedback, and small group discussions. Training programmes should include active, practice-oriented strategies. Oral presentations on communication skills, modelling, and written information should only be used as supportive strategies. To be able to compare the effectiveness of training programmes more easily in the future, general agreement on outcome measures has to be established. Copyright © 2010 Elsevier Ireland Ltd.

    Aarvold, J; Walton, G

    1992-12-01

    Compact Disc Read Only Memory (CD-ROM) represents an exciting innovation in nurse education yet paradoxically has a potential to induce disillusionment and frustration. Purchasers of systems may well find that their investment does not bring the benefits they had been lead to expect. CD-ROM systems have the capacity to generate huge quantities of data on an equally large number of nursing topics. Arguably this very capability ensures certain 'built-in' problems. The purpose of this articles is to provide nurse teachers with information about CD-ROM, to highlight the resource implications of CD-ROM use and to consider the relative merits of various teaching and learning methods. To be worthwhile, strategies developed must be part of an information retrieval skills programme.

    2009-09-01

    Full Text Available The need for the utilization of various teaching strategies by lecturers when facilitating learning cannot be overemphasized. The aim of this study was to establish if lecturers at a Nursing College in Mpumalanga were using teaching strategies that could facilitate the personal development of nursing learners. A quantitative approach was followed for this study. The participants of the study were all lecturers at a Nursing College in Mpumalanga. Data was gathered by means of a questionnaire. Descriptive statistics were used to describe and summarize data regarding the type of teaching strategies used and the recommendations that could enhance the utilization of various teaching strategies. The data revealed that the teaching strategies mostly utilized required active participation of the learners namely: formal/informal writing of assignments; learner-led class presentation; group sessions; clinical case studies; role-playing and clinical rounds. Inclusion of certain strategies such as problem-based learning, structured accompaniment and computer literacy for learners could enhance the personal development of nursing learners. Although lecturers did use some of the teaching strategies that could enhance the personal development of nursing learners, staff development regarding the utilization of various teaching strategies was highlighted as an important factor to be considered. Other findings revealed that lack of resources have a negative influence on the utilization of various teaching strategies.

  13. Reinventing medical teaching and learning for the 21st century: Blended and flipped strategies

    Full Text Available There has been a recent rapid increase in the integration of flipped and blended modes of learning into Australian university classrooms. In the move to realize the benefits of these modes of delivery, universities are spending a great deal of time focusing on course redesign and upskilling teachers to assist in the adoption of these new methods of instruction. Large-scale blended learning projects have been completed at The University of Newcastle, Australia. One such project has been the integration of flipped and blended learning strategies into the redesign of the 1st year medical science course as part of a total undergraduate medical curriculum redesign. This course involves a large number of lecturers from a wide variety of disciplines. This involved not only the redesign of this course but also the introduction of new teaching materials and learning objects. To ensure success, this work required input from three groups: the academics teaching the course, the students taking the course, and the instructional designers who create the learning objects. The University of Newcastle, Australia, was instrumental in introducing problem-based learning (PBL to medical schools in Australian universities with its initial intake of medical students in 1978 and continues the use of this methodology as its primary teaching approach. As the current project develops, it has become apparent the pioneering work previously undertaken to implement PBL, in fact, had incorporated many of the pedagogical principles and strategies of what is now considered blended learning in the flipped classroom (albeit without the technology components. This paper argues that our teachers and students will more easily adapt to the requirements inherent in blended or flipped learning due to previous familiarity with PBL strategies.

    Many teachers fall into the pattern of "assumptive teaching" (Herber 1970), assuming that other instructors will teach students the important strategies they need for learning. In this case, tools and strategies may not be taught outside of reading or language arts because a science teacher can say, "It's not my job." However, a sixth-grade team…

    Full Text Available The traditional teaching method has been widely questioned on the development of skills and abilities in training healthcare professionals. In the traditional methodology the main transmitter of knowledge is the teacher while students assume passive spectator role. Some Brazilian institutions broke with this model, structuring the curriculum to student-centered learning. Some medical schools have adopted the Problem Based Learning (PBL, a methodology that presents problem questions, to be encountered by future physicians, for resolution in small tutorial groups. Our work proposes to apply an active teaching-learning methodology addressing carbohydrate metabolism during the discipline of biochemistry for under graduation students from pharmacy course. Thus, the academic content was presented through brief and objective talks. Later, learners were split into tutorial groups for the resolution of issues in context. During the activities, the teacher drove the discussion to the issues elucidation. At the end of the module learners evaluated the teaching methodology by means of an applied questionnaire and the developed content was evaluated by an usual individual test. The questionnaire analysis indicates that students believe they have actively participated in the teaching-learning process, being encouraged to discuss and understand the theme. The answers highlight closer ties between students and tutor. According to the professor, there is a greater student engagement with learning. It is concluded that an innovative methodology, where the primary responsibility for learning is centered in the student himself, besides to increase the interest in learning, facilitates learning by cases discussion in groups. The issues contextualization establishes a narrowing between theory and practice.

  1. Strategies for Teaching English Abroad: The Immersion Classroom

    Full Text Available English language development is best laid on the foundation of natural and social interactions which requires a great deal of sacrifice from educators who teach abroad (Snow, 1997. Learning to speak a new language grants learners a passport and highly coveted citizenship to a culturally interconnected world (Met & Lorenz, 1993; however, educators often face a daunting challenge. They must come up with comprehensive strategies which ensure that learners obtain requisite skills faster than might otherwise be deemed necessary. They must also employ non-verbal communication in place of the native language and secure a total commitment from students (Fortune, 2000. Finally, educators must leverage the brain’s information processing and retention ability against a very formidable threat: forgetting. The paper focuses on language immersion classroom strategies currently being used around the world, along with a discussion on how technology has been used to increase language and cultural competencies. This research has implications for educators and administrators who are interested in the impact that technology access has on learning when paired with a total immersion approach. This paper will present recommendations for international English language immersion programs, whose goals are to develop a total cultural competency for students aged 5-25 in environments where there are limited resources to aid in language immersion.

    2018-05-01

    Full Text Available This paper proposes a multi-objective optimization method for the start-up strategy of pumped storage units (PSU for the first time. In the multi-objective optimization method, the speed rise time and the overshoot during the process of the start-up are taken as the objectives. A precise simulation platform is built for simulating the transient process of start-up, and for calculating the objectives based on the process. The Multi-objective Particle Swarm Optimization algorithm (MOPSO is adopted to optimize the widely applied start-up strategies based on one-stage direct guide vane control (DGVC, and two-stage DGVC. Based on the Pareto Front obtained, a multi-objective decision-making method based on the relative objective proximity is used to sort the solutions in the Pareto Front. Start-up strategy optimization for a PSU of a pumped storage power station in Jiangxi Province in China is conducted in experiments. The results show that: (1 compared with the single objective optimization, the proposed multi-objective optimization of start-up strategy not only greatly shortens the speed rise time and the speed overshoot, but also makes the speed curve quickly stabilize; (2 multi-objective optimization of strategy based on two-stage DGVC achieves better solution for a quick and smooth start-up of PSU than that of the strategy based on one-stage DGVC.

    The objective of this study was to test the hypothesis that cooperative learning strategies will help to increase nutrition knowledge of nurses and nursing assistants caring for the elderly in different institutional communities of the Basque Country, Spain. The target population was a sample of volunteers, 16 nurses and 28 nursing assistants. Training consisted of 12 nutrition education sessions using cooperative strategies conducted over a period of 3 consecutive weeks. The assessment instruments included two pretest and two posttest questionnaires with questions selected in multiple-choice format. The first questionnaire was about general knowledge of applied nutrition (0-88 point scale) and the second one on geriatric nutrition knowledge (0-18 point scale). Data were analyzed using SPSS vs. 11.0. The outcomes indicated a significant increase in general nutrition knowledge (difference between the pre- and post-test mean score: 14.5+/-10.1; Pcooperative learning strategies could improve the nutrition knowledge of nursing staff. Additionally, the results of this study provide direction to continuing nutrition education program planners regarding appropriate content and methodology for programs.

  11. How Things Work: Teaching Physics in the Context of Everyday Objects

    Science.gov (United States)

    Bloomfield, Louis

    2015-03-01

    How Things Work is an unconventional introduction to physics, a course that starts with whole objects and looks inside them to see what makes them work. Effectively ``case-study physics,'' it is designed primarily for non-science students who are unsure of the role of physics in the world and are looking for relevance in their studies. How Things Work is essentially the generalization of context-based introductory courses (Physics of the Human Body, Physics of the Automobile, and Physics of Music) and demonstrates that when physics is taught in the context of ordinary objects, these students are enthusiastic about it, look forward to classes, ask insightful questions, experiment on their own, and find themselves explaining to friends and family how things in their world work. In this talk, I will discuss the concept and structure of a How Things Work course and look briefly at how to teach its objects and assess what students learn from it. Although this course focuses on concepts rather than on calculations, it is rich in physics and requires that students think hard about the world around them. It also teaches problem solving and logical thinking skills, and demands that students face their misconceptions and failures of intuition. Lastly, it is actually quantitative in many respects, though its results are usually more words than numbers: your weight, the battery's voltage, or the acceleration due to gravity.

    Langabeer, J

    1998-01-01

    As the healthcare marketplace, characterized by declining revenues and heavy price competition, continues to evolve toward managed care, teaching hospitals are being forced to act more like traditional industrial organizations. Profit-oriented behavior, including emphases on market strategies and competitive advantage, is now a necessity if these hospitals are going to survive the transition to managed care. To help teaching hospitals evaluate strategic options that maximize financial effectiveness, this study examined the financial and operating data for 100 major U.S. teaching hospitals to determine relationships among competitive strategy, market environment, and financial return on invested capital. Results should help major hospitals formulate more effective strategies to combat environmental turbulence.

    Full Text Available Vocabulary plays pivotal role in foreign language learning. However, vocabulary teaching and vocabulary learning in TEFL seems to be neglected. The study was aimed to investigate how vocabulary teaching and learning are perceived by teacher and students, strategies to teach and learn the vocabulary, and also influences of students’ vocabulary learning strategy on their vocabulary mastery. Accordingly, a mix method design was employed to one English teacher and 30 junior high school students to reveal the issues being investigated. The findings showed that both teacher and students have positive response on vocabulary teaching and learning. Concerning strategies, it was found that teacher mostly employed Fully-contextual strategy, meanwhile Determination and Metacognitive strategy were found as the most favored VLS chosen by students. The study also confirmed that there is a significant relationship between students’ vocabulary learning strategy and their vocabulary mastery (r-value Discovery = .023 and r-value Consolidating = .000, p<.05. It is recommended for EFL teachers to give a bigger portion to vocabulary in the EFL teaching and to teach vocabulary using the combination of fully-contextual and de-contextual strategy. It is also suggested to introduce students to various kinds of vocabulary learning strategies.

    Although the evidence in support of the variability of students' learning strategies has expanded in recent years, less is known about the explanatory base of these individual differences in terms of the joint influences of personal and contextual characteristics. Previous studies have often investigated how student learning is associated with either personal or contextual factors. This study takes an integrative research perspective into account and examines the joint effects of personality, academic motivation, and teaching strategies on students' learning strategies in a same educational context in first-year higher education. In this study, 1,126 undergraduate students and 90 lecturers from eight professional bachelor programmes in a university college participated. Self-report measures were used to measure students' personality, academic motivation, and learning strategies. Students' processing and regulation strategies are mapped using the Inventory of Learning Styles. Key characteristics of more content-focused versus learning-focused teaching strategies were measured. Multivariate multi-level analysis was used to take the nested data structure and interrelatedness of learning strategies into account. Different personality traits (openness, conscientiousness, and neuroticism) and academic motivation (amotivation, autonomous, and controlled motivation) were found to be independently associated with student learning strategies. Besides these student characteristics, also teaching strategies were found to be directly associated with learning strategies. The study makes clear that the impact of teaching strategies on learning strategies in first-year higher education cannot be overlooked nor overinterpreted, due to the importance of students' personality and academic motivation which also partly explain why students learn the way they do. © 2013 The British Psychological Society.

    2015-12-01

    Clinical skills are a critical component of pre-registration nurse education in the United Kingdom, yet there is widespread concern about the clinical skills displayed by newly-qualified nurses. Novel means of supporting clinical skills education are required to address this. A package of Reusable Learning Objects (RLOs) was developed to supplement pre-registration teaching on the clinical skill of administering injection medication. RLOs are electronic resources addressing a single learning objective whose interactivity facilitates learning. This article evaluates a package of five injection RLOs across three studies: (1) questionnaires administered to pre-registration nursing students at University of Nottingham (UoN) (n=46) evaluating the RLO package as a whole; (2) individual RLOs evaluated in online questionnaires by educators and students from UoN; from other national and international institutions; and healthcare professionals (n=265); (3) qualitative evaluation of the RLO package by UoN injection skills tutors (n=6). Data from all studies were assessed for (1) access to, (2) usefulness, (3) impact and (4) integration of the RLOs. Study one found that pre-registration nursing students rate the RLO package highly across all categories, particularly underscoring the value of their self-test elements. Study two found high ratings in online assessments of individual RLOs by multiple users. The global reach is particularly encouraging here. Tutors reported insufficient levels of student-RLO access, which might be explained by the timing of their student exposure. Tutors integrate RLOs into teaching and agree on their use as teaching supplements, not substitutes for face-to-face education. This evaluation encompasses the first years postpackage release. Encouraging data on evaluative categories in this early review suggest that future evaluations are warranted to track progress as the package is adopted and evaluated more widely.

    Many schools rely upon community preceptors for office-based education of medical students. These preceptors struggle to balance clinical care with the learning needs of students. We aim to gain a deeper understanding of the teaching rewards and challenges of current community preceptors. Five schools' family medicine clerkship directors conducted in-depth interviews of two exemplary preceptors at each of their programs. Following qualitative analysis of the interviews, three directors conducted one focus group at their school. The individual and group interviews were recorded, transcribed, and analyzed using grounded theory. Exemplary community preceptors described strategies to improve the learning environment and specific teaching approaches. Well-known teaching strategies such as role modeling, adjusting instruction to the learner's needs, and selecting patients appropriate for a specific student were used. They also described newer techniques such as co-learning and integrating technology, for example, accessing online, current practice guidelines together with the student. They detailed challenges to teaching, including time constraints and too much content to cover and provided advice about teaching tools. While challenged by clinical demands, preceptors enjoyed teaching and found it rewarding. They used time-proven teaching strategies as well as technology and online resources to facilitate ambulatory teaching. Community preceptors continue to struggle to integrate learners and the priorities of the medical school curriculum into the clinical environment. Further development of electronic tools and other resources to support the teaching needs of preceptors may contribute to learning and help minimize preceptor burden.

  3. Diffraction and interference–-a standard teaching topic using non-standard diffracting objects

    International Nuclear Information System (INIS)

    Gröber, S; Vetter, M; Eckert, B; Jodl, H-J

    2014-01-01

    This topic-–diffraction and interference-–is a standard topic in teaching wave optics in schools and universities as well as in physics practical labs. The theoretical presentation needs some knowledge in mathematics; the final formula for the intensity pattern as a function of all parameters such as number of slits N, slit width b, slit distance d, wavelength λ of light used is not too complicated. The experimental setup is standard and well known. In our opinion the shortage comes here from the relatively poor quality of scattering objects produced by photolithography and by the small number of various objects in N, b and d. We on the contrary offer objects produced by electron beam lithography with much higher contrast and larger resolution. As a consequence, students are allowed to study not only positions of a few maxima and minima of the interference pattern, but determine relative intensities of maxima and minima with respect to central maximum, details around sub-maxima, band shape and bandwidth. In addition, we generated 150 objects with a variety in N, b and d and also offer five different wavelengths. Since these objects are hardly available and not so easy to copy we offer this experiment as a remotely controlled laboratory experiment which means the real experiment located in A can be used by everyone with his or her computer located in B via the Internet.

    Established methods to train pediatric urology surgery by residency training programs require updating in response to administrative changes such as new, reduced trainee duty hours. Therefore, new objective methods must be developed to teach trainees. We approached this need by creating e-learning to teach attendings objective assessment of trainee skills using the Zwisch scale, an established assessment tool. The aim of this study was to identify whether or not e-learning is an appropriate platform for effective teaching of this assessment tool, by assessing inter-rater correlation of assessments made by the attendings after participation in the e-learning. Pediatric orchiopexy was used as the index case. An e-learning tool was created to teach attending surgeons objective assessment of trainees' surgical skills. First, e-learning content was created which showed the assessment method videotape of resident surgery done in the operating room. Next, attendings were enrolled to e-learn this method. Finally, the ability of enrollees to assess resident surgery skill performance was tested. Namely, test video was made showing a trainee performing inguinal orchiopexy. All enrollees viewed the same online videos. Assessments of surgical skills (Zwisch scale) were entered into an online survey. Data were analyzed by intercorrelation coefficient kappa analysis (strong correlation was ICC ≥ 0.7). A total of 11 attendings were enrolled. All accessed the online learning and then made assessments of surgical skills trainees showed on videotapes. The e-learning comprised three modules: 1. "Core concepts," in which users learned the assessment tool methods; 2. "Learn to assess," in which users learned how to assess by watching video clips, explaining the assessment method; and 3. "Test," in which users tested their skill at making assessments by watching video clips and then actively inputting their ratings of surgical and global skills as viewed in the video clips (Figure

    Informal educators frequently use real objects to connect visitors with science content that can otherwise seem abstract. Our NSF-funded project, "Hot Times in Cold Places," leverages this premise to teach about climate change through real objects associated with the nation's only permafrost tunnel, located in Fox, Alaska. We posit that touching real ice, holding Pleistocene bones, and seeing ice wedges in context allows learners to understand climate change in a direct and visceral manner. We are conducting ethnographic research to understand visitor experience at both the tunnel itself and at a permafrost museum exhibit that we are creating as part of the project. Research questions include: 1) What is the nature of visitor talk with respect to explanations about permafrost, tipping points, climate change, and geological time? 2) How do attributes of "realness" (scale, resolution, uniqueness, history and adherence to an original) affect visitor's experience of objects, as perceived through the senses and emotions? We use naturalistic observation, interviews, and videotaping to answer these questions. Analysis focuses on child-to-child talk, reciprocal talk between educator and child, and reciprocal talk between parent and child. Our results elucidate the value of real, vs. replicated and virtual objects, in informal learning, especially in the context of climate change education. An understanding of these factors can help informal learning educators make informed choices about program and exhibit design.

    Full Text Available Teach them to Fly: Strategies for Encouraging Active Online Learning Karen HARDIN Cameron University Lawton, OK, USA PROBLEM One of the hot topics in education in the past 10 years has been the shift of the role of the educator. Whereas, he has traditionally been the owner and deliverer of the knowledge (Sage on the stage, now his role is shifting to a guide and facilitator (guide by the side. The purpose is to give the students ownership in their own learning process. As technology becomes more sophisticated, automation is replacing students’ problem solving skills, critical thinking and sometimes patience. On one of my evaluations in a 1999 online course, a student criticized that, “she’s not doing the teaching, I’m doing the learning.” Of course in my desire to encourage active learning, I took the response as a compliment, but the student meant it as a criticism. I began pondering the reluctance of students to take control of the learning process. I’ve noticed this lack of problem solving, critical thinking and patience with young adults in the workplace. For example, I often visit Sam’s, a warehouse store owned by Wal-Mart. When I check out, I pay with a check. The computerized register will print the check for me, so I allow the cashier to do that. I often ask him or her to add $15 to the total to give me cash back. It’s amazing how long it takes these young adults to add $15 to the total because of their reliance on computers. In another situation, when I was in an outlet shoe store in Texas, I purchased a pair of sandals. After I checked out, I noticed a sign that promoted, “buy one, get a second for one cent.” Of course, I wanted to take advantage of this opportunity, so I told the cashier that I wanted to find another pair of shoes. She replied, “It’s too late, your transaction is complete. I wouldn’t know what to do.” I said, “It’s simple, I owe you one cent.” She said, “I don’t know how to make the computer fix it

    2018-01-01

    Full Text Available This paper proposes a coordinated hybrid force/position control strategy of robonaut performing object transfer operation. Firstly, the constraint relationships between robonaut and object are presented. Base on them, the unified dynamic model of the robonaut and object is established to design the hybrid force/position control method. The movement, the internal force and the external constraint force of the object are considered as the control targets of the control system. Finally, a MATLAB simulation of the robonaut performing object transfer task verifies the correctness and effectiveness of the proposed method. The results show that all the targets can be control accurately by using the method proposed in this paper. The presented control method can control both internal and external forces while maintaining control accuracy, which is a common control strategy.

    2017-06-01

    Full Text Available The national qualification framework of a country requires a certain level of knowledge and complexity of skills for an academic degree to be recognized. For architectural programs, student workload is heavy on design courses. Therefore, each course must be carefully developed to ensure that students are not overloaded. Teaching and learning strategies have different implications for courses, which occasionally result in overloading the students. This research aims to study the three main pillars of teaching and learning strategies for each design phase in pedagogic design studios. The most appropriate model for each teaching and learning strategy, including a set of the three main pillars, is then identified for each design phase. A practical strategy for managing design studios is also determined. The aforementioned three pillars are as follows: teaching and learning methods, assigned tasks or study aspects, and design communication techniques. Two research methods, namely, a literature review and a survey among design educators, are adopted. The literature review examines aspects that contribute to the design process and its phases, teaching methods, design skills, communication methods, and studio management strategies. On the basis of the literature review, the background of developments and practices in the design education process are used as constructive tools to develop the survey for design educators. Through the survey, the pillars of teaching and learning strategies that are frequently practiced in design studios are evaluated. Results of this study are classified into three ranks using the nature break classification method for numerical values. Subsequently, three priority models that correspond to teaching and learning strategies, as well as to the required skills and capabilities, are established. A group-based strategy with an interdisciplinary approach is also determined to be the most suitable technique for managing the

    Full Text Available Higher education institutions experience large classes despite the National Universities’ Commission’s (NUC and other supervisory agencies emphasis on carrying capacity of the institutions in Nigeria. The overpopulation affects effective teaching and learning and quality assurance. This study focused on perception of intern teachers of the use of interactive strategies in teaching Curriculum Studies in an online environment in a College of Education. 200 computer science students (intern teachers in a Curriculum Studies class formed the study sample. Three research questions guided the study. A structured and validated questionnaire with reliability index of 0.79, made up of 25 items constructed on a four-point Likert-type scale was administered on the students for data collection. The data were analysed using simple mean and the results showed that the intern teachers supported the use of the teaching strategies in an online class as a complement to the face to face method of teaching. They are also recommended as alternative strategies to reduce the problems associated with large classes. However, the research subjects were sceptical about the implementation of online teaching as a result of power supply and access to internet facilities. The findings have a far reaching implication for the 21st Century teaching and learning. Suggestions towards effective online teaching and learning were made especially with theGovernment’s reiteration of the need for Information and Communication Technology (ICT in the schools in Nigeria.

    Aglen, B

    2016-01-01

    The aim of this study is to review international scientific articles about pedagogical strategies to teach nursing students at bachelor degree evidence-based practice (EBP). A literature review including peer reviewed, original, empirical articles describing pedagogical interventions aimed at teaching bachelor's degree nursing students EBP in the period 2004-2014. Theories of discretion, knowledge transfer and cognitive maturity development are used as analytical perspectives. The main challenge teaching evidence based practice is that the students fail to see how research findings contribute to nursing practice. The pedagogical strategies described are student active learning methods to teach the students information literacy and research topics. Information literacy is mainly taught according to the stages of EBP. These stages focus on how to elaborate evidence from research findings for implementation into nursing practice. The articles reviewed mainly use qualitative, descriptive designs and formative evaluations of the pedagogical interventions. Although a considerable effort in teaching information literacy and research topics, nursing students still struggle to see the relevance evidence for nursing practice. Before being introduced to information literacy and research topics, students need insight into knowledge transfer and their own epistemic assumptions. Knowledge transfer related to clinical problems should be the learning situations prioritized when teaching EBP at bachelor level. Theoretical perspectives of cognitive maturity development, knowledge transfer and discretion in professional practice give alternative ways of designing pedagogical strategies for EBP. More research is needed to develop and test pedagogical strategies for EBP in light of these theories. Copyright © 2015. Published by Elsevier Ltd.

  20. Strategies for Teaching Maritime Archaeology in the Twenty First Century

    Science.gov (United States)

    Staniforth, Mark

    2008-12-01

    Maritime archaeology is a multi-faceted discipline that requires both theoretical learning and practical skills training. In the past most universities have approached the teaching of maritime archaeology as a full-time on-campus activity designed for ‘traditional’ graduate students; primarily those in their early twenties who have recently come from full-time undergraduate study and who are able to study on-campus. The needs of mature-age and other students who work and live in different places (or countries) and therefore cannot attend lectures on a regular basis (or at all) have largely been ignored. This paper provides a case study in the teaching of maritime archaeology from Australia that, in addition to ‘traditional’ on-campus teaching, includes four main components: (1) learning field methods through field schools; (2) skills training through the AIMA/NAS avocational training program; (3) distance learning topics available through CD-ROM and using the Internet; and (4) practicums, internships and fellowships. The author argues that programs to teach maritime archaeology in the twenty first century need to be flexible and to address the diverse needs of students who do not fit the ‘traditional’ model. This involves collaborative partnerships with other universities as well as government underwater cultural heritage management agencies and museums, primarily through field schools, practicums and internships.

  9. A novel approach for multiple mobile objects path planning: Parametrization method and conflict resolution strategy

    International Nuclear Information System (INIS)

    Ma, Yong; Wang, Hongwei; Zamirian, M.

    2012-01-01

    We present a new approach containing two steps to determine conflict-free paths for mobile objects in two and three dimensions with moving obstacles. Firstly, the shortest path of each object is set as goal function which is subject to collision-avoidance criterion, path smoothness, and velocity and acceleration constraints. This problem is formulated as calculus of variation problem (CVP). Using parametrization method, CVP is converted to time-varying nonlinear programming problems (TNLPP) and then resolved. Secondly, move sequence of object is assigned by priority scheme; conflicts are resolved by multilevel conflict resolution strategy. Approach efficiency is confirmed by numerical examples. -- Highlights: ► Approach with parametrization method and conflict resolution strategy is proposed. ► Approach fits for multi-object paths planning in two and three dimensions. ► Single object path planning and multi-object conflict resolution are orderly used. ► Path of each object obtained with parameterization method in the first phase. ► Conflict-free paths gained by multi-object conflict resolution in the second phase.

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

    2016-01-01

    Full Text Available The board game hobby has rapidly grown and evolved in recent years, but most of the non-digital games lack tips and tutorials and remain difficult to learn and teach effectively. In this project, we integrated a popular hobbyist approach to teaching modern strategy games with classical experiential learning elements (i.e., demonstration, observation, reflection, discussion and repeated experiences. We tested our model by teaching two modern board games to Japanese high school and university students. Questionnaires, gameplay data, self-ratings and discussions showed improved understanding and enjoyment, more strategic play and more interest in modern board games over the course of the instructional sequence. The model's repetition (the participants played each game three times was rated the most useful in terms of learning the games. Overall, the integrated model was largely successful in teaching strategy board games to new players, and we offer several recommendations for teachers, designers and researchers of board games.

    Nestor D. Roselli

    2016-04-01

    Full Text Available Collaborative learning is a construct that identifies a current strong field, both in face-to-face and virtual education. Firstly, three converging theoretical sources are analyzed: socio-cognitive conflict theory, intersubjectivity theory and distributed cognition theory. Secondly, a model of strategies that can be implemented by teachers to develop socio-cognitive collaboration is presented. This model integrates and systematizes several academic group animation techniques developed within the collaborative learning field. These integrated techniques, within a coherent and unified didactic intention, allow talking more about strategies than independent and dissociated techniques. Each strategy is specifically described, which refers to six areas: encouragement of dialogue, listening to others and reciprocal assessment; collaboration for negotiation and consensus building; activity organization; study and appropriation of bibliographic information; conceptual development; collective writing. These strategies proposed (designed to stimulate the collaboration between 2, 4 and exceptionally, 6 or 8 students are not the only possible strategies, they can be combined with the ones the teacher might suggest. The strict pattern of each strategy is a characteristic of the proposal. The teacher is also encouraged to benchmark the results obtained using each strategy and those obtained using individual or non-collaborative strategies. Finally, conclusions and recommendations for the implementation of these strategies are discussed.

    Full Text Available The cartoon after a time of ostracism is occupying a prominent place in the pedagogical processes; however, in the Ecuadorian educational context, limitations are still observed. This study aims to update the knowledge on the inclusion of the story in the teaching-learning process of history and contribute through its disclosure to reverse this situation. The authors studied agree that the culture of the image that the current society experiences has favored its approach to the educational context, revaluing its educational potentials confirming the category of teaching medium; fulfills the functions: didactic, communicative and critical. Its use as a powerful didactic, methodological and pedagogical resource is justified in that historical ideas are easily associated with visual representations, the description and information is captured in the subconscious of the reader, which allows its subsequent analysis and learning.

    The work develops an alternative methodology to teach the Physics principles of Parabolic Cannon Shot in the career of Bioengineering using instead the physic-biological relationship of the long jump performed in Athletics. This is a closer-to-reality example for this discipline, and it is a field- and computer laboratory-reproducible practice that is simple to do by using affordable technology, because the practice can be filmed by the students in a real setting for future analysis off classroom hours. The data extracted from the film can be analysed and used to learn the physics of motion of the participating athletes, and to draw conclusions from their hands-on experience. As a main factor of the proposal, this latter characteristic aims at motivating the students to work and participate within a collaborative framework, so as to motivate them to reason and respond the questionnaire issues that stems from a real experience. A significant improvement of knowledge transference is thus attained by promoting teaching (and self-teaching) through reality-based perception, analysis and learning). This work is undergoing its first stage, and its conclusions arise from the observations on team-work dynamics. Quantitative results are expected for the following stages which are under way of execution

    2007-02-01

    This study aimed to implement innovative teaching methods--blended learning strategies--that include the use of new information technologies in the teaching of human anatomy and to analyse both the impact of these strategies on academic performance, and the degree of user satisfaction. The study was carried out among students in Year 1 of the biology degree curriculum (human biology profile) at Pompeu Fabra University, Barcelona. Two groups of students were tested on knowledge of the anatomy of the locomotor system and results compared between groups. Blended learning strategies were employed in 1 group (BL group, n = 69); the other (TT group; n = 65) received traditional teaching aided by complementary material that could be accessed on the Internet. Both groups were evaluated using the same types of examination. The average marks presented statistically significant differences (BL 6.3 versus TT 5.0; P < 0.0001). The percentage pass rate for the subject in the first call was higher in the BL group (87.9% versus 71.4%; P = 0.02), reflecting a lower incidence of students who failed to sit the examination (BL 4.3% versus TT 13.8%; P = 0.05). There were no differences regarding overall satisfaction with the teaching received. Blended learning was more effective than traditional teaching for teaching human anatomy.

    The Taiwan Nursing Accreditation Council has proposed eight core professional nursing qualities including ethical literacy. Consequently, nursing ethics education is a required course for student nurses. These courses are intended to improve the ethical literacy. Moral sensitivity is the cornerstone of ethical literacy, and learning moral sensitivity is the initial step towards developing ethical literacy. To explore the effect of nursing ethics educational interventions based on multiple teaching strategies on student nurses moral sensitivity. Based on the visual, auditory and kinaesthetic model, three strategies were developed for determining the programme components and corresponding learning styles. This was a quasi-experimental study. A total of 234 junior-college student nurses participated in this study. All participants were aged 18-19 years. Ethical considerations: The study protocol was approved by the institutional review boards of Kaohsiung Veterans General Hospital. Only the participants who signed an informed consent form took part in the study. The participants were permitted to withdraw from the study at any point if they wished to do so without affecting their academic score. The scores of Modified Moral Sensitivity Questionnaire for Student Nurses were significantly improved after the intervention of integrating multiple teaching strategies ( p = .042). Significant relationships were observed between the satisfaction scores of two teaching strategies and moral sensitivity. The results indicated that using multiple teaching strategies is effective for promoting nursing ethics learning. This strategy was consistent with the student nurses' preferred learning style and was used to correct their erroneous ethical conceptions, assisting in developing their ethical knowledge.

    2007-01-01

    The literature highlights key benefits from debate as a teaching-learning strategy for developing critical thinking and analytical skills while fostering teamwork and communication. Authors report that this method of teaching-learning has been implemented successfully in nursing and occupational therapy programs and would benefit other academic programs in the health sciences, particularly in courses that cover controversial issues. Although there are disadvantages to using the debate as a teaching-learning strategy, the benefits far outweigh the disadvantages. In conclusion, debating is an effective pedagogical strategy because of the level of responsibility for learning and active involvement required by all student debaters. Moreover, it provides an experience by which students can develop competencies in researching current issues, preparing logical arguments, actively listening to various perspectives, differentiating between subjective and evidence-based information, asking cogent questions, integrating relevant information, and formulating their own opinions based on evidence. After the debate is over, students also report that the experience is FUN!

    This study examined how instructional challenges presented by gifted students shaped teachers’ instructional strategies. This study is a qualitative research grounded in a social constructivist framework. The participants were three high school science teachers who were teaching identified gifted students in both heterogeneously- and homogeneously-grouped classrooms. Major data sources are classroom observations and interviews. Data analysis indicated that these science teachers developed content-specific teaching strategies based on their understanding of gifted students, including: (a) instructional differentiation, e.g., thematic units, (b) variety in instructional mode and/or students’ products, (c) student grouping strategies and peer tutoring, (d) individualized support, (e) strategies to manage challenging questions, (f) strategies to deal with the perfectionism, and (g) psychologically safe classroom environments.

  11. ACTIVE LEARNING STRATEGIES IN TEACHING CROSS CULTURAL UNDERSTANDING FOR ENGLISH EDUCATION STUDENTS

    2017-02-01

    Full Text Available Cross Cultural Understanding (CCU is one of required courses in English Language Teaching which aims at connecting language and culture so that language learners can use foreign language appropriately, i.e. appropriate forms of language for appropriate context of situation. However, some obstacles usually occur during the course, for examples: students’ lack of understanding that lead to opinions stating that this is a boring and useless course, and large number of students within a class where lecturer must teach more than 40 students in one class. Considering the importance of CCU course as well as the needs to overcome the problems during this course, this paper proposes some particular teaching strategies to help students in apprehending CCU materials through students’ active participations. Active learning strategies are preferred by means of raising students’ participation and critical thinking so that the class would run more effectively. Other consideration in composing the strategies is to prepare English Education students to be future English language teachers by training their ability in teaching performance as well as connecting language and culture in English Language Teaching (ELT.   Keywords: language, culture, strategies, media, ELT

    2014-11-01

    Full Text Available By the advent of new theories and approaches toward language teaching, a lot of attention has been paid to the role of those approaches on language learners. Superiority of psychology and linguistics in the area of language teaching urged scholars to develop new theories and techniques through a defined procedure. Most of the time the role of teacher’s experience as learner has been neglected. The present study was an attempt to investigate the relationship between EFL In-service teachers’ language learning strategies and their beliefs toward teaching methodologies. To find the relationship, a questionnaire was applied. The questionnaire in the study consists of three measures: (1 the individual background; (2 strategy inventory for language learning (Version 7.0 for ESL/EFL, Oxford, 1990; and, (3 beliefs toward English teaching methodologies (Chen, 2005. It was given to 252 in-service English teachers (136 female, 116 male majoring in TEFL. To analyze the quantitative data of the present study, descriptive as well as inferential analysis including ANOVA and Pearson’s correlations were used to investigate the relationships between language learning strategies and teaching beliefs toward EFL methodologies. Based on the teachers’ answers to the questionnaire, there was a meaningful relationship between language learning strategies and teacher’s methodology. The information provided in the present research can be helpful for teachers, policy holders of institutes and material developers. This study has also some implications for the researchers interested in teacher’s education studies.

  13. Teaching science for conceptual change: Toward a proposed taxonomy of diagnostic teaching strategies to gauge students' personal science conceptions

    Science.gov (United States)

    Shope, Richard Edwin, III

    Science instruction aims to ensure that students properly construct scientific knowledge so that each individual may play a role as a science literate citizen or as part of the science workforce (National Research Council, 1996, 2000). Students enter the classroom with a wide range of personal conceptions regarding science phenomena, often at variance with prevailing scientific views (Duschl, Hamilton, & Grandy, 1992; Hewson, 1992). The extensive misconceptions research literature emphasizes the importance of diagnosing students' initial understandings in order to gauge the accuracy and depth of what each student knows prior to instruction and then to use that information to adapt the teaching to address student needs. (Ausubel, 1968; Carey, 2000; Driver et al., 1985; Karplus & Thier, 1967; Mintzes, Wandersee, & Novak, 1998; Osborne & Freyberg, 1985; Project 2061, 1993; Strike & Posner, 1982, 1992; Vygotsky, 1934/1987). To gain such insight, teachers diagnose not only the content of the students' personal conceptions but also the thinking processes that produced them (Strike and Posner, 1992). Indeed, when teachers design opportunities for students to express their understanding, there is strong evidence that such diagnostic assessment also enhances science teaching and learning (Black & William, 1998). The functional knowledge of effective science teaching practice resides in the professional practitioners at the front lines---the science teachers in the classroom. Nevertheless, how teachers actually engage in the practice of diagnosis is not well documented. To help fill this gap, the researcher conducted a study of 16 sixth grade science classrooms in four Los Angeles area middle schools. Diagnostic teaching strategies were observed in action and then followed up by interviews with each teacher. Results showed that teachers use strategies that vary by the complexity of active student involvement, including pretests, strategic questions, interactive discussion

    2017-12-01

    Full Text Available The purpose of this study is to assess the use of educational software and mobile device applications to teach about the human body at a rural school. It is an action research, with a qualitative approach, developed in 2016 and involving 14 students from the 8th year Elementary Education at the Escola Estadual Sol Nascente in Confresa-MT. The chosen software and application was the Human Body Atlas and 3D Human Body Systems, emphasizing on the digestive and circulation systems. The results from the pre-and post-test, which comprised 20 questions together, corroborate the hypothesis that the use of digital educational objects benefits the education process. Students learned better the systems in comparison with when only traditional resources, such as a didactic book, was used. Such advancement could be harnessed to the fact that the resources make use of 3D images and point out each part of the body, besides providing important information and curiosities about the subject. It is therefore expected that digital technologies may be increasingly inserted and explored in pedagogical practices, since those resources allow for studying and solving queries, by broadening educational space and time.

    Gulotta, M

    1995-01-01

    LabVIEW is a graphic object-oriented computer language developed to facilitate hardware/software communication. LabVIEW is a complete computer language that can be used like Basic, FORTRAN, or C. In LabVIEW one creates virtual instruments that aesthetically look like real instruments but are controlled by sophisticated computer programs. There are several levels of data acquisition VIs that make it easy to control data flow, and many signal processing and analysis algorithms come with the software as premade VIs. In the classroom, the similarity between virtual and real instruments helps students understand how information is passed between the computer and attached instruments. The software may be used in the absence of hardware so that students can work at home as well as in the classroom. This article demonstrates how LabVIEW can be used to control data flow between computers and instruments, points out important features for signal processing and analysis, and shows how virtual instruments may be used in place of physical instrumentation. Applications of LabVIEW to the teaching laboratory are also discussed, and a plausible course outline is given. PMID:8580361

  18. Use of memory strategies among younger and older adults: Results from objective and subjective measures

    Directory of Open Access Journals (Sweden)

    Aline Teixeira Fabricio

    Full Text Available Abstract Memory plays a fundamental role in the identity of people and in human life, as it enables us to interpret our surroundings and make decisions. It is known that the aging process can be accompanied by cognitive decline in some memory sub systems. However, the use of memory strategies can help encoding and retrieval of new information. Objective: The aim of this study was to identify and compare, using objective and subjective measures, which recall strategies are used spontaneously by young and older adults. Methods: Twenty-six first-year college students, and thirty-three seniors enrolled at the Third Age University of the same campus, completed a visual memory test including 18 black and white pictures, memorized a short story, and completed an open question about memory strategies, a memory check list to indicate strategies used, and a memory self-efficacy scale. The Bousfield categorization measure was also calculated from the recall protocol. Results: Young adults demonstrated better performance than the older adults on the memory tasks, and were also more confident. Both groups reported using similar strategies. Conclusion: Young and older adults seem to tackle memory tasks in similar ways but young adults outperform seniors.

    2015-01-01

    The study was designed to examine the effects of motivation on young children's recall for object names and early-emerging mnemonic activities. Seventy-two 4-year-old children were randomly assigned to 1 of 3 instructional conditions: incidental, intentional, or motivational. Each child was shown 10 small toy objects and provided a 90 s study period prior to recall. The children's mnemonic behaviors were videotaped for subsequent coding. The children in the incidental condition were instructed to simply look at the toys while children in the intentional and motivational condition were given explicit instructions to remember. The motivational group was also told that they could keep whichever toys they remembered. A recognition memory task was employed to examine the extent to which the stimuli were encoded during the study period. The children's recall memory did not vary as a function of instructional condition. Children's use of singular versus multiple strategies was calculated, along with a weighted summary score giving most weight to the participant's use of mature mnemonic strategies. Significant differences in strategy use were found, favoring the motivational condition. Significant positive correlations were found between the weighted summary scores and object recall, and the teacher ratings of mastery motivation and object recall. Mastery motivation was found to be unrelated to the strategic summary scores, failing to mediate strategic behaviors. The results suggest that when providing incentives to remember, children apparently engaged in more effortful mnemonic processing in order to remember the items, even though a greater number of items were not recalled.

  2. Multi-objective reliability optimization of series-parallel systems with a choice of redundancy strategies

    International Nuclear Information System (INIS)

    Safari, Jalal

    2012-01-01

    This paper proposes a variant of the Non-dominated Sorting Genetic Algorithm (NSGA-II) to solve a novel mathematical model for multi-objective redundancy allocation problems (MORAP). Most researchers about redundancy allocation problem (RAP) have focused on single objective optimization, while there has been some limited research which addresses multi-objective optimization. Also all mathematical multi-objective models of general RAP assume that the type of redundancy strategy for each subsystem is predetermined and known a priori. In general, active redundancy has traditionally received greater attention; however, in practice both active and cold-standby redundancies may be used within a particular system design. The choice of redundancy strategy then becomes an additional decision variable. Thus, the proposed model and solution method are to select the best redundancy strategy, type of components, and levels of redundancy for each subsystem that maximizes the system reliability and minimize total system cost under system-level constraints. This problem belongs to the NP-hard class. This paper presents a second-generation Multiple-Objective Evolutionary Algorithm (MOEA), named NSGA-II to find the best solution for the given problem. The proposed algorithm demonstrates the ability to identify a set of optimal solutions (Pareto front), which provides the Decision Maker (DM) with a complete picture of the optimal solution space. After finding the Pareto front, a procedure is used to select the best solution from the Pareto front. Finally, the advantages of the presented multi-objective model and of the proposed algorithm are illustrated by solving test problems taken from the literature and the robustness of the proposed NSGA-II is discussed.

    2010-06-01

    This paper proposes a multi-objective bidding strategy for a generation company (GenCo) in uniform price spot market using non-dominated sorting particle swarm optimization (NSPSO). Instead of using a tradeoff technique, NSPSO is introduced to solve the multi-objective strategic bidding problem considering expected profit maximization and risk (profit variation) minimization. Monte Carlo simulation is employed to simulate rivals' bidding behavior. Test results indicate that the proposed approach can provide the efficient non-dominated solution front effectively. In addition, it can be used as a decision making tool for a GenCo compromising between expected profit and price risk in spot market.

    Teaching strategies are essential in order to facilitate meaningful learning and the development of high-level thinking skills in students. To compare three teaching methodologies (problem-based learning, case-based teaching and traditional methods) in terms of the learning outcomes achieved by nursing students. This quasi-experimental research was carried out in the Nursing Degree programme in a group of 74 students who explored the subject of The Oncology Patient through the aforementioned strategies. A performance test was applied based on Bloom's Revised Taxonomy. A significant correlation was found between the intragroup theoretical and theoretical-practical dimensions. Likewise, intergroup differences were related to each teaching methodology. Hence, significant differences were estimated between the traditional methodology (x-=9.13), case-based teaching (x-=12.96) and problem-based learning (x-=14.84). Problem-based learning was shown to be the most successful learning method, followed by case-based teaching and the traditional methodology. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The question as to whether entrepreneurship could be learned - and whether it should be taught as part of University Studies in general, more particularly as part of business studies, has been discussed for a number of years. The most widespread answer today seems to be positive; yes......, entrepreneurship can be learned and should be taught. A major problem is that the traditional forms of teaching at universities and business schools have shown themselves quite inappropriate for enhancing the motivation and competencies of students towards innovation and entrepreneurship. This phenomenon has...... the secure context of the university auditorium or in small firms - or perhaps somewhere in between academia and practice. A fourth dilemma is whether students should work individually or collectively and a fifth is the question of how the substance of what is taught is formulated; whether entrepreneurship...

    2015-01-01

    The availability of reliable evidence for teaching practices after professional development is limited across science, technology, engineering, and mathematics disciplines, making the identification of professional development “best practices” and effective models for change difficult. We aimed to determine the extent to which postdoctoral fellows (i.e., future biology faculty) believed in and implemented evidence-based pedagogies after completion of a 2-yr professional development program, Faculty Institutes for Reforming Science Teaching (FIRST IV). Postdocs (PDs) attended a 2-yr training program during which they completed self-report assessments of their beliefs about teaching and gains in pedagogical knowledge and experience, and they provided copies of class assessments and video recordings of their teaching. The PDs reported greater use of learner-centered compared with teacher-centered strategies. These data were consistent with the results of expert reviews of teaching videos. The majority of PDs (86%) received video ratings that documented active engagement of students and implementation of learner-centered classrooms. Despite practice of higher-level cognition in class sessions, the items used by the PDs on their assessments of learning focused on lower-level cognitive skills. We attributed the high success of the FIRST IV program to our focus on inexperienced teachers, an iterative process of teaching practice and reflection, and development of and teaching a full course.

    2010-02-01

    This paper reports on an investigation of the effectiveness an intervention using several different methods for teaching solution chemistry. The teaching strategy comprised a four-step approach derived from a constructivist view of learning. A sample consisting of 44 students (18 boys and 26 girls) was selected purposively from two different Grade 9 classes in the city of Trabzon, Turkey. Data collection employed a purpose-designed `solution chemistry concept test', consisting of 17 items, with the quantitative data from the survey supported by qualitative interview data. The findings suggest that using different methods embedded within the four-step constructivist-based teaching strategy enables students to refute some alternative conceptions, but does not completely eliminate student alternative conceptions for solution chemistry.

    Hu, Wang; Yen, Gary G; Luo, Guangchun

    2017-06-01

    It is a daunting challenge to balance the convergence and diversity of an approximate Pareto front in a many-objective optimization evolutionary algorithm. A novel algorithm, named many-objective particle swarm optimization with the two-stage strategy and parallel cell coordinate system (PCCS), is proposed in this paper to improve the comprehensive performance in terms of the convergence and diversity. In the proposed two-stage strategy, the convergence and diversity are separately emphasized at different stages by a single-objective optimizer and a many-objective optimizer, respectively. A PCCS is exploited to manage the diversity, such as maintaining a diverse archive, identifying the dominance resistant solutions, and selecting the diversified solutions. In addition, a leader group is used for selecting the global best solutions to balance the exploitation and exploration of a population. The experimental results illustrate that the proposed algorithm outperforms six chosen state-of-the-art designs in terms of the inverted generational distance and hypervolume over the DTLZ test suite.

    2011-01-01

    Memory plays a fundamental role in the identity of people and in human life, as it enables us to interpret our surroundings and make decisions. It is known that the aging process can be accompanied by cognitive decline in some memory sub systems. However, the use of memory strategies can help encoding and retrieval of new information. The aim of this study was to identify and compare, using objective and subjective measures, which recall strategies are used spontaneously by young and older adults. Twenty-six first-year college students, and thirty-three seniors enrolled at the Third Age University of the same campus, completed a visual memory test including 18 black and white pictures, memorized a short story, and completed an open question about memory strategies, a memory check list to indicate strategies used, and a memory self-efficacy scale. The Bousfield categorization measure was also calculated from the recall protocol. Young adults demonstrated better performance than the older adults on the memory tasks, and were also more confident. Both groups reported using similar strategies. Young and older adults seem to tackle memory tasks in similar ways but young adults outperform seniors.

    Full Text Available Innovation of the practice of teaching through interactive models, new roles of teacher and student, and preference of the activity of the student in the learning process, are found in the basis of changes that is taking place in education in Kosovo. We are talking about actions that aim to improve the quality, durability and applicability of the knowledge that students acquire in school. So today, in all cycles of education, new teaching models are applied that determine the student as an active subject in the teaching process. Interactive teaching is recommended and implemented with significant uplift, because it is becoming a need of modern education, and part of the needs of teachers and students. The extent and quality of mastering the knowledge in a large extent depends on the way work is organized in class and therefore interactive teaching is a key factor to improve the efficiency and quality of learning. Interactive teaching influences a higher level of motivation in the classroom by developing the cooperation between the students and activates the responsibility of the students. They learn about the harmonization of positions, collective action, tolerance and modern communication using different sources of knowledge. In this paper we define the terms of interaction and interactive teaching and actualize a number of other issues related to interactive teaching in the early school age. Also, this paper presents only a part of the authentic results of the two studies combined, one of the results obtained by means of questionnaires given to teachers from nine schools in Kosovo and from the results of interviews conducted with professionists as a focus group. Results from the survey show that interactive learning methods are extensively covered by the school age. They are already very popular in professional environments or communities of teachers since practice proved their effectiveness.

  13. Efficacy of ACA strategies in biography-driven science teaching: an investigation

    Science.gov (United States)

    MacDonald, Grizelda L.; Miller, Stuart S.; Murry, Kevin; Herrera, Socorro; Spears, Jacqueline D.

    2013-12-01

    This study explored the biography-driven approach to teaching culturally and linguistically diverse students in science education. Biography-driven instruction (BDI) embraces student diversity by incorporating students' sociocultural, linguistic, cognitive, and academic dimensions of their biographies into the learning process (Herrera in Biography-driven culturally responsive teaching. Teachers College Press, New York, 2010). Strategies have been developed (Herrera, Kavimandan and Holmes in Crossing the vocabulary bridge: differentiated strategies for diverse secondary classrooms. Teachers College Press, New York, 2011) that provide teachers with instructional routines that facilitate BDI. Using systematic classroom observations we empirically demonstrate that these activate, connect, affirm, strategies are likely to be effective in increasing teachers' biography-driven practices. Implications for theory and practice are discussed.

    Directory of Open Access Journals (Sweden)

    Abraham Magendzo-Kolstrein

    2015-09-01

    Full Text Available The purpose of this article, which can be envision as an essay, is to present a pedagogical-didactic strategy for human rights education focusing on the controversy. Advancements and setbacks faced by human rights education in Latin America are exposed in order to support this strategy. Therefore, it indicates that education has denied the conflict and explains the need for its inclusion under the idea of ‘controversial issue’. Additionally, the existence of conflicts in the interpretation, violation and/or respect for human rights is pointed out. The principal tensions that cross human rights are displayed. Based on the above, the need to support the existence of a human rights education focusing on the conflict and central components of its teaching strategy are described, and it ends by referring to its didactic approach and the role which should be assumed by faculty when teaching human rights including the conflict.

    Highlights: • Suppression of oscillations in a thermocapillary flow is addressed by optimization. • The gradient of the objective function is obtained by solving the adjoint equations. • The issue of choosing an objective function is investigated. - Abstract: The problem of suppressing flow oscillations in a thermocapillary flow is addressed using a gradient-based control strategy. The physical problem addressed is the “open boat” process of crystal growth, the flow in which is driven by thermocapillary and buoyancy effects. The problem is modeled by the two-dimensional unsteady incompressible Navier–Stokes and energy equations under the Boussinesq approximation. The goal of the control is to suppress flow oscillations which arise when the driving forces are such that the flow becomes unsteady. The control is a spatially and temporally varying temperature gradient boundary condition at the free surface. The control which minimizes the flow oscillations is found using a conjugate gradient method, where the gradient of the objective function with respect to the control variables is obtained from solving a set of adjoint equations. The issue of choosing an objective function that can be both optimized in a computationally efficient manner and optimization of which provides control that damps the flow oscillations is investigated. Almost complete suppression of the flow oscillations is obtained for certain choices of the objective function.

    The set points of supervisory control strategy are optimized with respect to energy use and thermal comfort for existing HVAC systems. The set point values of zone temperatures, supply duct static pressure, and supply air temperature are the problem variables, while energy use and thermal comfort are the objective functions. The HVAC system model includes all the individual component models developed and validated against the monitored data of an existing VAV system. It serves to calculate energy use during the optimization process, whereas the actual energy use is determined by using monitoring data and the appropriate validated component models. A comparison, done for one summer week, of actual and optimal energy use shows that the on-line implementation of a genetic algorithm optimization program to determine the optimal set points of supervisory control strategy could save energy by 19.5%, while satisfying the minimum zone airflow rates and the thermal comfort. The results also indicate that the application of the two-objective optimization problem can help control daily energy use or daily building thermal comfort, thus saving more energy than the application of the one-objective optimization problem.

    2015-01-01

    Full Text Available The article is devoted to some of the teaching strategies based on the peculiarities of belles-lettres text. The author of the article analyses the peculiarities of the belles-lettres text which exert influence on the process of teaching reading skills and thus should be taken into account by foreign language teachers in their work with this type of text. The author argues that teaching belles-lettres reading skills should be centered on the five-level communication process between writer and reader. The teacher's aim is to create or adjust a system of reading instruction within the five levels so that he/she could improve students' reading skills. In the article, it is stated that the process of teaching reading skills should be congruent with the process of interpersonal communication between writer and reader. The author outlines the content of the teacher's approach to the work with this type of text within the process of foreign language instruction. The author describes two approaches to teaching belles-lettres reading skills as well as shows the prospects for the subjective approach. He also states high productivity and effectiveness of the subjective approach in teaching foreign languages. The article shows the importance of involving students who specialize in sciences into the process of belles-lettres reading while studying a foreign language for specific purposes.

    An important factor contributing to the quality of clinical education is instructors' teaching performance. The aim of this study was to identify clinical instructors' most effective teaching strategies from nursing and midwifery students' perspectives. This was a descriptive cross-sectional study. All third- and fourth-year bachelor's nursing and midwifery students studying at the Nursing and Midwifery Faculty of Kurdistan University of Medical Sciences were recruited to the study by using the census method. The study instrument consisted of a demographic questionnaire and the self-report 30-item Clinical Instructors' Effective Teaching Strategies Inventory. The SPSS v.16.0 was used for data analysis. The most effective teaching strategies of clinical instructors from nursing and midwifery students' perspectives were respectively 'treating students, clients, and colleagues with respect' and 'being eager for guiding students and manage their problems'. Clinical instructors need to be eager for education and also be able to establish effective communication with students. Empowering clinical instructors in specialized and technical aspects of clinical education seems necessary. Copyright © 2015 Elsevier Ltd. All rights reserved.

  19. The Combined Effects of Classroom Teaching and Learning Strategy Use on Students' Chemistry Self-Efficacy

    For students to be successful in school chemistry, a strong sense of self-efficacy is essential. Chemistry self-efficacy can be defined as students' beliefs about the extent to which they are capable of performing specific chemistry tasks. According to Bandura (Psychol. Rev. 84:191-215, 1977), students acquire information about their level of self-efficacy from four sources: performance accomplishments, vicarious experiences, verbal persuasion, and physiological states. No published studies have investigated how instructional strategies in chemistry lessons can provide students with positive experiences with these four sources of self-efficacy information and how the instructional strategies promote students' chemistry self-efficacy. In this study, questionnaire items were constructed to measure student perceptions about instructional strategies, termed efficacy-enhancing teaching, which can provide positive experiences with the four sources of self-efficacy information. Structural equation modeling was then applied to test a hypothesized mediation model, positing that efficacy-enhancing teaching positively affects students' chemistry self-efficacy through their use of deep learning strategies such as metacognitive control strategies. A total of 590 chemistry students at nine secondary schools in Hong Kong participated in the survey. The mediation model provided a good fit to the student data. Efficacy-enhancing teaching had a direct effect on students' chemistry self-efficacy. Efficacy-enhancing teaching also directly affected students' use of deep learning strategies, which in turn affected students' chemistry self-efficacy. The implications of these findings for developing secondary school students' chemistry self-efficacy are discussed.

  20. Teaching Strategis Designed to Change the Undergraduate Experience for College Women Learning Chemistry

    Khan, Samia

    A college for women has been cited as one of the most productive origins of female physical science doctorates in the United States. A case study was conducted to investigate teaching strategies that support the retention of women in the physical sciences, based on evidence from one of the college's most notable instructors and her teaching strategies. The strategies this teacher used included a personal "contract", confidence building techniques, and science internships. Data were collected from classroom documents, classroom observations, teacher interviews, student focus groups, student feedback sheets, Likert-response student surveys, and student final exams. Evidence from the Likert-response survey and focus groups suggested that the contract increased students' likelihood of success in the course and that confidence-building strategies improved students' confidence in their ability to succeed in science. An analysis of students' final exam scores indicated that student marks improved after the introduction of the aforementioned teaching innovations: 4% of students taking the same science course with the same teacher earned less than a C-, compared to a previous three-year average of 18% of students with below C- grades. In addition, notably fewer minority women dropped the course than they had in the past. The findings of this study suggest that this teacher's strategies may have played a part in retaining these women in the physical sciences. Based on the data, a theoretical model is proposed that suggests how switching or "fading" out of the course may have been addressed and how multiple teaching strategies can work in concert with each other to contribute to women's positive experiences in the physical sciences.

    Full Text Available Process-oriented rainfall-runoff models are designed to approximate the complex hydrologic processes within a specific catchment and in particular to simulate the discharge at the catchment outlet. Most of these models exhibit a high degree of complexity and require the determination of various parameters by calibration. Recently, automatic calibration methods became popular in order to identify parameter vectors with high corresponding model performance. The model performance is often assessed by a purpose-oriented objective function. Practical experience suggests that in many situations one single objective function cannot adequately describe the model's ability to represent any aspect of the catchment's behaviour. This is regardless of whether the objective is aggregated of several criteria that measure different (possibly opposite aspects of the system behaviour. One strategy to circumvent this problem is to define multiple objective functions and to apply a multi-objective optimisation algorithm to identify the set of Pareto optimal or non-dominated solutions. Nonetheless, there is a major disadvantage of automatic calibration procedures that understand the problem of model calibration just as the solution of an optimisation problem: due to the complex-shaped response surface, the estimated solution of the optimisation problem can result in different near-optimum parameter vectors that can lead to a very different performance on the validation data. Bárdossy and Singh (2008 studied this problem for single-objective calibration problems using the example of hydrological models and proposed a geometrical sampling approach called Robust Parameter Estimation (ROPE. This approach applies the concept of data depth in order to overcome the shortcomings of automatic calibration procedures and find a set of robust parameter vectors. Recent studies confirmed the effectivity of this method. However, all ROPE approaches published so far just identify

    Quiz-based and collaborative teaching strategies have previously been found to be efficient for the improving meaningful learning of physiology during lectures. These approaches have, however, not been investigated during laboratory exercises. In the present study, we compared the impact of solving quizzes individually and in groups with conventional teaching on the immediate learning during a laboratory exercise. We implemented two quizzes in a mandatory 4-h laboratory exercise on baroreflex physiology. A total of 155 second-year medical students were randomized to solve quizzes individually (intervention group I, n = 57), in groups of three to four students (intervention group II, n = 56), or not to perform any quizzes (control; intervention group III, n = 42). After the laboratory exercise, all students completed an individual test, which encompassed two recall questions, two intermediate questions, and two integrated questions. The integrated questions were of moderate and advanced difficulty, respectively. Finally, students completed an evaluation form. Intervention group I reached the highest total test scores and proved best at answering the integrated question of advanced difficulty. Moreover, there was an overall difference between groups for student evaluations of the quality of the teaching, which was highest for intervention group II. In conclusion, solving quizzes individually during a laboratory exercise may enhance learning, whereas solving quizzes in groups is associated with higher student satisfaction.

    Full Text Available The present work proposes a multi-objective improved teaching-learning based optimization (MO-ITLBO algorithm for unconstrained and constrained multi-objective function optimization. The MO-ITLBO algorithm is the improved version of basic teaching-learning based optimization (TLBO algorithm adapted for multi-objective problems. The basic TLBO algorithm is improved to enhance its exploration and exploitation capacities by introducing the concept of number of teachers, adaptive teaching factor, tutorial training and self-motivated learning. The MO-ITLBO algorithm uses a grid-based approach to adaptively assess the non-dominated solutions (i.e. Pareto front maintained in an external archive. The performance of the MO-ITLBO algorithm is assessed by implementing it on unconstrained and constrained test problems proposed for the Congress on Evolutionary Computation 2009 (CEC 2009 competition. The performance assessment is done by using the inverted generational distance (IGD measure. The IGD measures obtained by using the MO-ITLBO algorithm are compared with the IGD measures of the other state-of-the-art algorithms available in the literature. Finally, Lexicographic ordering is used to assess the overall performance of competitive algorithms. Results have shown that the proposed MO-ITLBO algorithm has obtained the 1st rank in the optimization of unconstrained test functions and the 3rd rank in the optimization of constrained test functions.

    Routine work in nuclear medicine requires the careful elution of radioactivity and its subsequent, storage and handling. Though all effort is maintained to prevent any “spill” of this radioactivity, accidents are bound to happen. The response to this spill is a methodically worked out a plan that is written and adopted as a “standard operating procedure.” This protocol is taught to all involved in the area of working as a mock drill/apprenticeship model. No formal evaluation of learning is in place except for the mock drills. The objectively structured assessment of technical skills (OSATS) is a variation on the Objective Structured Clinical Examination, which is a form of workplace based assessment. The OSATS is cited in the Accreditation Council of Graduate Medical Education evaluation toolbox on the website as the most desirable evaluation tool for the patient care topics. It is the objective of this paper is to introduce the “OSATS” for teaching, and assessment of the learning, of the protocol for the management of radioactive spill. As a review of the literature on the subject failed to reveal any such teaching protocol/material/document for this important technical skill, we hope that it may act as a landmark for the development of teaching and assessment of other technical skills also

  13. An effective docking strategy for virtual screening based on multi-objective optimization algorithm

    2009-02-01

    Full Text Available Abstract Background Development of a fast and accurate scoring function in virtual screening remains a hot issue in current computer-aided drug research. Different scoring functions focus on diverse aspects of ligand binding, and no single scoring can satisfy the peculiarities of each target system. Therefore, the idea of a consensus score strategy was put forward. Integrating several scoring functions, consensus score re-assesses the docked conformations using a primary scoring function. However, it is not really robust and efficient from the perspective of optimization. Furthermore, to date, the majority of available methods are still based on single objective optimization design. Results In this paper, two multi-objective optimization methods, called MOSFOM, were developed for virtual screening, which simultaneously consider both the energy score and the contact score. Results suggest that MOSFOM can effectively enhance enrichment and performance compared with a single score. For three different kinds of binding sites, MOSFOM displays an excellent ability to differentiate active compounds through energy and shape complementarity. EFMOGA performed particularly well in the top 2% of database for all three cases, whereas MOEA_Nrg and MOEA_Cnt performed better than the corresponding individual scoring functions if the appropriate type of binding site was selected. Conclusion The multi-objective optimization method was successfully applied in virtual screening with two different scoring functions that can yield reasonable binding poses and can furthermore, be ranked with the potentially compromised conformations of each compound, abandoning those conformations that can not satisfy overall objective functions.

A hybrid multi-objective differential evolution optimization algorithm, which successfully integrates Pareto non-dominated sorting with differential evolution algorithm and improves individual crowding distance mechanism and mutation strategy to avoid premature and unevenly search, is designed to achieve Pareto optimal set of this model. Moreover, fuzzy set theory and entropy weighting method are employed to extract one of the Pareto optimal solutions as the general best solution. Several optimization runs have been carried out on different cases of generation bidding and scheduling. The results confirm the potential and effectiveness of the proposed approach in solving the multi-objective optimization problem of generation bidding and scheduling. In addition, the comparison with the classical optimization algorithms demonstrates the superiorities of the proposed algorithm such as integrality of Pareto front, well-distributed Pareto-optimal solutions, high search speed.

    The authors present an overview of current graduate medical education (GME) issues, particularly the financial challenges to teaching hospitals resulting from the Balanced Budget and Tax Payer Relief Acts of 1997 and other recent market-driven factors. They describe in detail the nature of Medicare GME payments before and after the 1997 legislation, with specific examples, and explain the negative financial impact of the legislation and aspects of the legislation that are designed to alleviate that impact. Other factors influencing GME program size and composition are also discussed, including oversupplies or shortages of physicians, the concern that teaching hospitals are using public funds to train international medical graduates, changing training requirements, etc. The authors also describe a recent consulting assignment during which they assisted a major teaching hospital to develop a GME strategy that was responsive to the organization's mission and patients and that took into account future GME financing challenges. Detailed explanations are given of how the consultants analyzed the hospital's GME programs and finances, developed and ranked key institution-specific program criteria (strategic, organizational and operational, and financial), and, in consultation with all key stakeholders, formulated a GME strategy specific to the institution's needs. The authors conclude by cautioning that each institution's GME strategy will be different, but that it is important for institutions to develop such strategies to better face future challenges.

    Full Text Available This study ascertained the relationship between difficulties and coping strategies as related to teaching performance of West Visayas State University-Janiuay Campus (WVSU-JC faculty for the School Year 2014-2015. The survey-correlational method was used with teaching performance as dependent variables, experienced economic difficulties as the independent variable, and coping strategy as moderator variable. The participants in the study were the 52 faculty who were selected through purposive sampling. Data were gathered through a researcher-made questionnaire-checklist and Faculty Performance Evaluation System. The statistical tools used were frequency count, rank, mean, standard deviation, and Pearson's Product-Moment Coefficient of Correlation. All statistical computations were availed of through the Statistical Package for the Social Sciences (SPSS software. Results revealed that the top economic difficulty experienced by faculty was limited cash. The topmost coping strategy employed by faculty was buying only basic foods or things for household. The faculty also experienced economic difficulty to a “moderate extent.” Nevertheless, the performance of the faculty was found to be “outstanding.” Teachers were affected by such financial crisis. However, despite their experienced economic difficulties, as major agents for change, they performed their best for the improvement of quality education. No significant relationships existed between coping strategies and teaching performance of faculty.

    Full Text Available This study investigated the integrating possibilities within each creative arts subject. The objective was to optimize the limited teaching time, generally allocated to each art subject in schools, by developing a pedagogical strategy for its successful implementation. While the study was limited to South African schools, the results have global relevance and significance in the ongoing global trendsetting and discourse on arts education. In South Africa the previous National Curriculum Statement (NCS, 2002 integrated music, dance, drama and visual arts where possible, while the new Curriculum and Assessment Policy Statement (CAPS, 2011 offers two elective art subjects in the senior phase (Grades 7-9, each taught separately an hour per week during school hours and one hour per week after school, thereby attempting to extend the teaching time. This qualitative enquiry used documentary analyses, teacher interviews, and student group discussions for the collection of data. Pre-determined and emergent codes based on grounded theory showed that it is possible to integrate theory with practice within one art subject by teaching theoretical work in the context of practical work, thus optimizing the limited time allocated to arts and culture education in school timetables.

    2018-01-01

    Full Text Available Using Pareto optimization in Multi-Objective Reinforcement Learning (MORL leads to better learning results for network defense games. This is particularly useful for network security agents, who must often balance several goals when choosing what action to take in defense of a network. If the defender knows his preferred reward distribution, the advantages of Pareto optimization can be retained by using a scalarization algorithm prior to the implementation of the MORL. In this paper, we simulate a network defense scenario by creating a multi-objective zero-sum game and using Pareto optimization and MORL to determine optimal solutions and compare those solutions to different scalarization approaches. We build a Pareto Defense Strategy Selection Simulator (PDSSS system for assisting network administrators on decision-making, specifically, on defense strategy selection, and the experiment results show that the Satisficing Trade-Off Method (STOM scalarization approach performs better than linear scalarization or GUESS method. The results of this paper can aid network security agents attempting to find an optimal defense policy for network security games.

In the consulted sources, no study has been found to collect and analyze the results of research on this subject using a systematic method. To try to fill this gap, a systematic literature review was conducted with the aim of summarizing the studies on the use of Collaborative Work as a didactic strategy for teaching/learning programming. Initially, through a search in four (4 databases of scientific publications, 95 studies published in the last five (5 years were obtained. After careful analysis of each one of them, only 40 were found to meet the review requirements. This analysis resulted in the synthesis of eleven (11 Collaborative Learning Techniques (CLT that implement such strategy. Subsequently, they were grouped into 19 common names of strategies found in the documents, i.e. the collaborative strategies or techniques associated with each study. The review also showed a significant amount of contributions from the research community that constitute an important basis for future work. This demonstrates that Collaborative Work is increasingly consolidated as a valid and relevant didactic strategy, not only in programming teaching/learning, but also in other areas of knowledge including computer science.

  5. A strategy to objectively evaluate the necessity of correcting detected target deviations in image guided radiotherapy

    Image guided radiotherapy technologies are being increasingly utilized in the treatment of various cancers. These technologies have enhanced the ability to detect temporal and spatial deviations of the target volume relative to planned radiation beams. Correcting these detected deviations may, in principle, improve the accuracy of dose delivery to the target. However, in many situations, a clinical decision has to be made as to whether it is necessary to correct some of the deviations since the relevant dosimetric impact may or may not be significant, and the corresponding corrective action may be either impractical or time consuming. Ideally this decision should be based on objective and reproducible criteria rather than subjective judgment. In this study, a strategy is proposed for the objective evaluation of the necessity of deviation correction during the treatment verification process. At the treatment stage, without any alteration from the planned beams, the treatment beams should provide the desired dose coverage to the geometric volume identical to the planning target volume (PTV). Given this fact, the planned dose distribution and PTV geometry were used to compute the dose coverage and PTV enclosure of the clinical target volume (CTV) that was detected from imaging during the treatment setup verification. The spatial differences between the detected CTV and the planning CTV are essentially the target deviations. The extent of the PTV enclosure of the detected CTV as well as its dose coverage were used as criteria to evaluate the necessity of correcting any of the target deviations. This strategy, in principle, should be applicable to any type of target deviations, including both target deformable and positional changes and should be independent of how the deviations are detected. The proposed strategy was used on two clinical prostate cancer cases. In both cases, gold markers were implanted inside the prostate for the purpose of treatment setup

  6. Bringing Scholarship to the Classroom: Strategies for promoting research through teaching

    Full Text Available An issue all academics grapple with is how to strike the desired balance between research and teaching. This balance is heavily influenced by the type of institution where one seeks employment. At liberal arts colleges, excellence is expected in the classroom and a premium is put on faculty student interaction. The expectation, however, is to be teacher-scholar, not simply teacher. And indeed, the desire of most professors at liberal arts colleges is to remain active in their field. With limited time and large teaching demands, the challenge becomes one of continuously making progress on one’s research agenda. When asked to consider how to connect scholarship and teaching on the “Bringing Scholarship to the Classroom: Japan Studies” panel at the ASIANetwork conference in March 2008, I realized I had developed several strategies to link my research and teaching. What I also realized was that all these strategies were influenced by the fact that I was a junior professor vying for tenure. That is, my motivation for connecting scholarship and teaching was largely instrumental. In addition to being able to speak more passionately about topics we research and therefore engage students more fully, I would argue that finding ways to incorporate one’s research in as many classes as possible is a way to better tackle the dual role of teacher-scholar. Connecting research and teaching can accelerate one’s research agenda simply by preventing the liberal arts professor from being torn in too many different directions.

  7. National plan for achieving the objectives of the OSPAR strategy with regard to radioactive substances

    International Nuclear Information System (INIS)

    2002-06-01

    This report describes the Swedish plans for implementation of the OSPAR strategy with regard to radioactive substances. Revised release regulations for nuclear facilities are the primary tool in the work for achieving the objectives of the OSPAR strategy. The limitation of releases of radioactive substances shall be based on optimisation of radiation protection (ALARA) and the use of best available technique (BAT). Technical improvements to reduce discharges from the nuclear facilities include changes of daily routines in the waste management. Plans for the future include the introduction of new purification techniques and modernisation of waste facilities. The implementation of the new regulations, and in particular the introduction of BAT in terms of reference and target values for nuclear power reactors indicates the foreseen reductions of releases for the forthcoming five years. After that time, new reference and target values will be established. The regulations stipulate that monitoring of releases of radioactive substances shall be reported to the authorities. These reports will fulfil the demand for following-up of the progress of implementing the strategy. In particular, in yearly reports the progress towards reaching the target values will be monitored

    The Universitat de Valencia is the second most popular university in Europe for the Erasmus exchange program in Europe. Close to 2000 Erasmus students attend yearly the lectures in Valencia University. Most of them arrive to Valencia -also to Granada, Barcelona and Salamanca- because the cultural attractive. Valencia moreover offers a warm and dry climate, which make the University of Valencia very popular for the Erasmus students. In 2003 a survey developed by the International Exchange Coordinator of the Geography Degree shown that 33 % of the student choose the Valencia University because the night-life, 22 % because the climate, 23 % because the suggestion of a friend (mainly due to the climate and night-life) and only 22 % because of the academic background of the university. Another survey at the end of the 2003-2004 year shown that 84 % of the Erasmus student did not know that Valencia had a lagoon (called l'Albufera) nearby, and that 23 % of the students ignored that the main park of the city was developed on the river bed, after the artificial change of the mouth of the river to a southern position due to the flood of 1957. The Erasmus students new almost nothing about the landscape of the surroundings and the city of Valencia. A strategy was developed since 2003 by the International Exchange Coordinator of the Geography Degree to show to the students coming from the Erasmus project the landscape of the Valencia Country by means of field visits to the key locations in two days. One day is devoted to the coastal land where lagoons, river mouths and population concentration are the main topics. The second day a trekking on the mountains located at the Sierra de Enguera give an idea to the students of the Desertification processes after the land abandonment during the 50 and 60's. The students attending the lectures and the two days excursion (280 in 2008) found this excursion as a key point in their adaptation to the new university as they know how is the

    The aim of this systematic review was to find best teaching strategies for teaching evidence-based practice (EBP) to undergraduate health students that have been adopted over the last years in healthcare institutions worldwide. The authors carried out a systematic, comprehensive bibliographic search using Medline database for the years 2005 to March 2015 (updated in March 2016). Search terms used were chosen from the USNLM Institutes of Health list of MeSH (Medical Subject Headings) and free text key terms were used as well. Selected articles were measured based on the inclusion criteria of this study and initially compared in terms of titles or abstracts. Finally, articles relevant to the subject of this review were retrieved in full text. Critical appraisal was done to determine the effects of strategy of teaching evidence-based medicine (EBM). Twenty articles were included in the review. The majority of the studies sampled medical students (n=13) and only few conducted among nursing (n=2), pharmacy (n=2), physiotherapy/therapy (n=1), dentistry (n=1), or mixed disciplines (n=1) students. Studies evaluated a variety of educational interventions of varying duration, frequency and format (lectures, tutorials, workshops, conferences, journal clubs, and online sessions), or combination of these to teach EBP. We categorized interventions into single interventions covering a workshop, conference, lecture, journal club, or e-learning and multifaceted interventions where a combination of strategies had been assessed. Seven studies reported an overall increase to all EBP domains indicating a higher EBP competence and two studies focused on the searching databases skill. Followings were deduced from above analysis: multifaceted approach may be best suited when teaching EBM to health students; the use of technology to promote EBP through mobile devices, simulation, and the web is on the rise; and the duration of the interventions varying form some hours to even months was

    Full Text Available The effects of cooperative learning and traditional learning on the effectiveness and constraining factors of physical fitness teaching under various teaching conditions were studied. Sixty female students in Grades 7–8 were sampled to evaluate their learning of health and physical education (PE according to the curriculum for Grades 1–9 in Taiwan. The data were quantitatively and qualitatively collected and analyzed. The overall physical fitness of the cooperative learning group exhibited substantial progress between the pretest and posttest, in which the differences in the sit-and-reach and bent-knee sit-up exercises achieved statistical significance. The performance of the cooperative learning group in the bent-knee sit-up and 800 m running exercises far exceeded that of the traditional learning group. Our qualitative data indicated that the number of people grouped before a cooperative learning session, effective administrative support, comprehensive teaching preparation, media reinforcement, constant feedback and introspection regarding cooperative learning strategies, and heterogeneous grouping are constraining factors for teaching PE by using cooperative learning strategies. Cooperative learning is considered an effective route for attaining physical fitness among students. PE teachers should consider providing extrinsic motivation for developing learning effectiveness.

    Full Text Available The acquisition of idiomatic expressions is one of the primary challenges to learners of English as a Second Language (ESL in multilingual contexts such as Kenya; yet, the learners are expected to use these expressions in their writing. The study on which this paper is based sought to assess the teaching of English idiomatic expressions in Kenyan secondary schools with a view to establishing the challenges teachers face in teaching the expressions and, thereafter, proposing effective strategies that can be applied for effective teaching of English idioms to ESL speakers.  Ten teachers of English from both rural and urban secondary schools in Kenya were interviewed to find out the actual practices in their classrooms, the difficulties they face, and the effective strategies they employ for successful teaching of English idioms. The data collected were qualitatively analyzed. First, the study notes that it is possible to infer semantic relations between the literal sense of individual parts of an idiom and its meaning when interpreting compositional idioms. Second, there is incongruity between form and meaning when dealing with non compositional idioms since their semantic interpretation cannot be retrieved by means of their constituent parts. The study concludes that an understanding of the etymology of idioms can improve the comprehension and retention of idioms. The study recommends that idioms should be taught effectively in schools because the acquisition of idioms by learners will be an important indicator of their mastery of the English language. Keywords: Idiomatic expressions, semantic relations, compositional idioms, non compositional idioms

    Full Text Available SMPN 3 Lengayang has applied STAD as a type of cooperative learning to improve students’ passiveness. The learning is initiated by forming study groups and assigning tasks to be discussed together. However, in fact the learning is not effective that the students still can not understand the materials properly. It is noticable that the tasks given have been done by one student only, meanwhile the others are less serious and rely on those who are willing to do the group work. This is a field reasearch which describes the implementation of STAD in teaching PAI qualitatively. Data collection techniques used are in the form of observation, interviews, and documentation. As the result; 1 the planning of STAD strategy in teaching PAI at SMPN 3 Lengayang does not yet fulfill the requirement such as in organizing teaching materials (systematic/systematic demands with unsuitable time allocation, and detail of learning scenario (strategy step / method at each stage not clearly illustrated. 2 the implementation of STAD type in teaching PAI at SMPN 3 Lengayang is not fully implemented from the six STAD type cooperative learning steps, namely on teamwork and quiz, and 3 the evaluation in STAD type co-operative learning at SMPN 3 Lengayang is a written test or in the form of quiz. In addition, a test through a special quiz for individual assessment while group assessment is taken from group work. Especially the group with the highest score is given an additional mark.

    Full Text Available Teaching self-care must ensure the intestinal stoma patient more independence concerning the family and health professionals. The planning involves the assessment of the clinical and socio-demographic data, and the conditions for the self-care. This study aimed at identifying strategies to teach self-care for intestinal stoma patients in the scientific production. We used an integrative review on MEDLINE, PUBMED, LILACS, CINAHL and COCHRANE bases from 2005 to 2011, 7 papers were selected. In the perioperative teaching, multimedia, telephone follow-up, personal meetings, interactive material through the Internet were used, besides the continuing education of the health professionals. These different strategies profess the needs of each individual that promote self-care learning about the surgery and its consequences, skills development and the necessary adaptation of the condition of a stoma patient. The nurse needs to have technical and scientific knowledge on surgical technique, demarcation, treatment, complications, and skills for the teaching of self-care.

    Over the past decade, the dedicated search for kilometer-size near-Earth objects (NEOs), potentially hazardous objects (PHOs), and potential Earth impactors has led to a boost in the rate of discoveries of these objects. The catalog of known NEOs is the fundamental ingredient used to develop a model for the NEOs population, either by assessing and correcting for the observational bias (Jedicke et al., 2002), or by evaluating the migration rates from the NEOs source regions (Bottke et al., 2002). The modeled NEOs population is a necessary tool used to track the progress in the search of large NEOs (Jedicke et al., 2003) and to try to predict the distribution of the ones still undiscovered, as well as to study the sky distribution of potential Earth impactors (Chesley & Spahr, 2004). We present a method to model the NEOs population in all six orbital elements, on a finely grained grid, allowing us the design and test of targeted and optimized search strategies. This method relies on the observational data routinely reported to the Minor Planet Center (MPC) by the Catalina Sky Survey (CSS) and by other active NEO surveys over the past decade, to determine on a nightly basis the efficiency in detecting moving objects as a function of observable quantities including apparent magnitude, rate of motion, airmass, and galactic latitude. The cumulative detection probability is then be computed for objects within a small range in orbital elements and absolute magnitude, and the comparison with the number of know NEOs within the same range allows us to model the population. When propagated to the present epoch and projected on the sky plane, this provides the distribution of the missing large NEOs, PHOs, and potential impactors.

    The availability of reliable evidence for teaching practices after professional development is limited across science, technology, engineering, and mathematics disciplines, making the identification of professional development "best practices" and effective models for change difficult. We aimed to determine the extent to which postdoctoral fellows (i.e., future biology faculty) believed in and implemented evidence-based pedagogies after completion of a 2-yr professional development program, Faculty Institutes for Reforming Science Teaching (FIRST IV). Postdocs (PDs) attended a 2-yr training program during which they completed self-report assessments of their beliefs about teaching and gains in pedagogical knowledge and experience, and they provided copies of class assessments and video recordings of their teaching. The PDs reported greater use of learner-centered compared with teacher-centered strategies. These data were consistent with the results of expert reviews of teaching videos. The majority of PDs (86%) received video ratings that documented active engagement of students and implementation of learner-centered classrooms. Despite practice of higher-level cognition in class sessions, the items used by the PDs on their assessments of learning focused on lower-level cognitive skills. We attributed the high success of the FIRST IV program to our focus on inexperienced teachers, an iterative process of teaching practice and reflection, and development of and teaching a full course. © 2015 D.

    Full Text Available Current research investigates the ideas and practices of a team of teachers of the Natural Sciences working in schools in the state of Paraná, Brazil, with regard to pedagogical workshops as teaching and learning strategies on Hydrographic Basin as theme. A continuous formation course was conducted on the theme, with data retrieved by a questionnaire applied prior to the course and after the development of workshops by the teachers. Films, recordings and descriptive memorials were analyzed according to content analysis. Results showed that teachers endeavored to problematize in the pedagogical workshops, coupled to teachers´ mediation to go beyond common sense. Students´ participation was the great progress mediated by workshops. On the other hand, interdisciplinarity and the problematization of teaching were the limiting presuppositions for their execution. The undertaking enhanced a better understanding of pedagogical workshops in the teaching of the sciences, with the need for greater investments in teachers´ continuous formation to enhance the development of teaching practices that attend to current demands in science teaching.

  18. Teaching evolution (and all of biology) more effectively: Strategies for engagement, critical reasoning, and confronting misconceptions.

    Science.gov (United States)

    Nelson, Craig E

    2008-08-01

    The strength of the evidence supporting evolution has increased markedly since the discovery of DNA but, paradoxically, public resistance to accepting evolution seems to have become stronger. A key dilemma is that science faculty have often continued to teach evolution ineffectively, even as the evidence that traditional ways of teaching are inferior has become stronger and stronger. Three pedagogical strategies that together can make a large difference in students' understanding and acceptance of evolution are extensive use of interactive engagement, a focus on critical thinking in science (especially on comparisons and explicit criteria) and using both of these in helping the students actively compare their initial conceptions (and publicly popular misconceptions) with more fully scientific conceptions. The conclusion that students' misconceptions must be dealt with systematically can be difficult for faculty who are teaching evolution since much of the students' resistance is framed in religious terms and one might be reluctant to address religious ideas in class. Applications to teaching evolution are illustrated with examples that address criteria and critical thinking, standard geology versus flood geology, evolutionary developmental biology versus organs of extreme perfection, and the importance of using humans as a central example. It is also helpful to bridge the false dichotomy, seen by many students, between atheistic evolution versus religious creationism. These applications are developed in detail and are intended to be sufficient to allow others to use these approaches in their teaching. Students and other faculty were quite supportive of these approaches as implemented in my classes.

    Full Text Available The goal of the present work is to develop some strategies based on research in neurosciences that contribute to the teaching and learning of mathematics. The interrelationship of education with the brain, as well as the relationship of cerebral structures with mathematical thinking was discussed. Strategies were developed taking into consideration levels that include cognitive, semiotic, language, affect and the overcoming of phobias to the subject. The fundamental conclusion was the imperative educational requirement in the near future of a new teacher, whose pedagogic formation must include the knowledge on the cerebral function, its structures and its implications to education, as well as a change in pedagogy and curricular structure in the teaching of mathematics.

    Full Text Available Abstract This paper analyses the use of the Cumbuca Method as a teaching strategy to develop reading skills in engineering students. Despite their importance, reading skills are little stimulated in engineering undergraduate courses. Teamwork, communication, organization and exposure of ideas, time management are also important skills to new employees. The Cumbuca Method was created to disseminate quality concepts among company employees, by discussing text related to a given topic of interest. This analysis is based on a qualitative approach involving a sample of 200 engineering undergraduates from Operations Management discipline at a public University in the State of Sao Paulo, Brazil. The results showed that the use of this teaching strategy inducted improvements to regular reading and debate among students.

    This paper studies the usefulness of a short film in teaching strategies for parents of children with cancer to cope with the situation. The short film is based on an analysis of the transcripts from eight sessions of a self-help group. The short film has been evaluated by psychologists working for each of the parent groups belonging to the Federation of parents of children with cancer. Furthermore, the film has been exhibited in group sessions that took place in the Valencia and Alicante branches of ASPANION (Association of Parents with Oncologic Children in the Valencia Region). About 70% of the experts have declared that the film is a valuable resource for teaching useful strategies to parents. The film also improves the group sessions since it addresses a number of issues that had not been addressed before, and it stimulates the participation of, and communication between, parents during the session.

    Full Text Available This research aims to analyze motivational strategies in teaching English as foreign language at 7th grade of Junior High School 7 Kuningan and to analyze students‟ attitudes towards motivational strategies that were applied by teachers in teaching EFL. The researchers used qualitative research by using classroom observation, interview, and questionnaires. The result taken from classroom observation and interview show teacher 1 and teacher 3 applied motivational strategies completely based on the phases of motivational strategies. Thus, the students responded these strategies positively. On the other hand, teacher 2 applied motivational strategies incompletely because the teacher missed the first phases. This was responded negatively by students. Therefore, the students were actively involved in teaching and learning process conducted by teacher 1 and teacher 2, but the students were passively involved in teaching and learning process conducted by teacher 2. Furthermore, the result taken from questionnaires shows that students gave positive attitudes towards the teacher 1 (88.25%, teacher 2 (79.02%, and teacher 3 (85.71%. Based on the findings, it can be concluded that the way the teachers applied motivational strategies in teaching EFL determined students‟ attitudes towards motivational strategies applied by teachers in teaching EFL.

    2005-12-01

    The DLESE Teaching Box project is both a professional development opportunity and an educational resource development project providing a pedagogic context that support teachers' use of data in the classroom. As a professional development opportunity, it is designed to augment teachers' science content knowledge, enhance their use of inquiry teaching strategies, and increase their confidence and facility with using digital libraries and online learning resources. Teams of educators, scientists, and instructional designers work together during a three part Teaching Box Development Workshop series to create Teaching Boxes on Earth system science topics. The resulting Teaching Boxes use Earth system science conceptual frameworks as their core and contain inquiry-based lessons which model scientific inquiry and process by focusing on the gathering and analysis of evidence. These lines of evidence employ an Earth systems approach to show how processes across multiple spheres, for example, how the biosphere, atmosphere, and geosphere interact in a complex Earth process. Each Teaching Box has interconnected lessons that provide 3-6 weeks of instruction, incorporate National and California science standards, and offer guidance on teaching pathways through the materials. They contain up-to-date digital materials including archived and real-time data sets, simulations, images, lesson plans, and other resources available through DLESE, NSDL, and the participating scientific institutions. Background information provided within the Box supports teacher learning and guides them to facilitate student access to the tools and techniques of authentic, modern science. In developing Teaching Boxes, DLESE adds value to existing educational resources by helping teachers more effectively interpret their use in a variety of standards-based classroom settings. In the past twelve months we have had over 100 requests for Teaching Box products from teachers and curriculum developers from

    Compare the outreach of a promotional educational strategy that focuses on active participation and compare it with a more traditional approach to medical training. A quasi-experimental design was approved by the research committee. We compared the outreach of two different approaches to medical training. We administered a validated instrument that included 72 items that analyze statements used to measure educational tasks in the form of duplets through 3 indicators. A group that included seven physicians that were actively participating in teaching activities was stratified according to teaching approaches. One of the approaches was a traditional one and the other included a promotional strategy aimed at increasing participation. All participants signed informed consent before answering the research instruments. Statistical analysis was done using non-parametric tests. Mann-Whitney results did not show differences among the group in the preliminary analysis. A second analysis with the same test after the interventions found significant differences (p d" 0.018) in favor of those subjects that had participated in the promotional approach mainly in the indicator measuring "consequence". The Wilcoxon test showed that all participants in the promotional approach increased significantly (pd" 0.018) in 3 main indicators as compared with the control group. A promotional strategy aimed at increasing physician participation constitutes a more profitable approach when compared with traditional teaching methods.

  10. Teaching basic medical sciences at a distance: strategies for effective teaching and learning in internet-based courses.

    In recent years, the Internet has become an effective and accessible delivery mechanism for distance education. In 2003, 81% of all institutions of higher education offered at least one fully online or hybrid course. By 2005, the proportion of institutions that listed online education as important to their long-term goals had increased by 8%. This growth in available online courses and their increased convenience and flexibility have stimulated dramatic increases in enrollment in online programs, including the Veterinary Technology Distance Learning Program (VT-DLP) at Purdue University. Regardless of the obvious benefits, distance learning (DL) can be frustrating for the learners if course developers are unable to merge their knowledge about the learners, the process of instructional design, and the appropriate uses of technology and interactivity options into effective course designs. This article describes strategies that we have used to increase students' learning of physiology content in an online environment. While some of these are similar, if not identical, to strategies that might be used in a face-to-face (f2f) environment (e.g., case studies, videos, concept maps), additional strategies (e.g., animations, virtual microscopy) are needed to replace or supplement what might normally occur in a f2f course. We describe how we have addressed students' need for instructional interaction, specifically in the context of two foundational physiology courses that occur early in the VT-DLP. Although the teaching and learning strategies we have used have led to increasingly high levels of interaction, there is an ongoing need to evaluate these strategies to determine their impact on students' learning of physiology content, their development of problem-solving skills, and their retention of information.

    Merrill, Alison Saricks

    The purpose of this quasi-experimental quantitative mixed design study was to compare the effectiveness of brain-based teaching strategies versus a traditional lecture format in the acquisition of higher order cognition as determined by test scores. A second purpose was to elicit student feedback about the two teaching approaches. The design was a 2 x 2 x 2 factorial design study with repeated measures on the last factor. The independent variables were type of student, teaching method, and a within group change over time. Dependent variables were a between group comparison of pre-test, post-test gain scores and a within and between group comparison of course examination scores. A convenience sample of students enrolled in medical-surgical nursing was used. One group (n=36) was made up of traditional students and the other group (n=36) consisted of second-degree students. Four learning units were included in this study. Pre- and post-tests were given on the first two units. Course examinations scores from all four units were compared. In one cohort two of the units were taught via lecture format and two using constructivist activities. These methods were reversed for the other cohort. The conceptual basis for this study derives from neuroscience and cognitive psychology. Learning is defined as the growth of new dendrites. Cognitive psychologists view learning as a constructive activity in which new knowledge is built on an internal foundation of existing knowledge. Constructivist teaching strategies are designed to stimulate the brain's natural learning ability. There was a statistically significant difference based on type of teaching strategy (t = -2.078, df = 270, p = .039, d = .25)) with higher mean scores on the examinations covering brain-based learning units. There was no statistical significance based on type of student. Qualitative data collection was conducted in an on-line forum at the end of the semester. Students had overall positive responses about the

    2014-01-01

    Full Text Available This paper deals with the issue of the management cycle of Competitive Intelligence. The author describes the process of Competitive Intelligence in Czech corporate management. He concludes that in most cases, the Competitive Intelligence operations are directed by the top management, and the attention of Competitive Intelligence is being paid to Key Intelligence Topics (KIT. The Competitive Intelligence is then focused on the output of strategic analyses, complemented in some cases with a summary (synthesis of acquired intelligence plus some signal intelligence (SIGINT. The results of the Competitive Intelligence produced in such a way are actually the outputs mostly applicable in operational management and mostly unsuitable for strategic management. However, top managers abroad almost invariably need the data relevant to the future situation since their decisions are of strategic nature. The following section of the paper is devoted to the conceptual solution of Competitive Intelligence, i.e. the Competitive Intelligence objectives linked with the development strategy of the corporation. Here the author arrives at three basic development strategies: a. the corporation desires status quo, i.e. to keep its market position as it is, b. the corporation is out to expand, and c. the corporation intends not only to keep its existing and dominant market position but strives for its long-term dominance to last.

    The development of science and technology requires reform in the utilization of various resources for mathematics teaching and learning process. One of the efforts that can be made is the implementation of GeoGebra-assisted Reciprocal Teaching strategy in mathematics instruction as an effective strategy in improving students’ cognitive, affective, and psychomotor abilities. This research is intended to implement GeoGebra-assisted Reciprocal Teaching strategy in improving abstraction ability, lateral thinking, and mathematical persistence of junior high school students. It employed quasi-experimental method with non-random pre-test and post-test control design. More specifically, it used the 2x3 factorial design, namely the learning factors that included GeoGebra-assisted Reciprocal Teaching and conventional teaching learning, and levels of early mathematical ability (high, middle, and low). The subjects in this research were the eighth grade students of junior high school, taken with purposive sampling. The results of this research show: Abstraction and lateral abilities of students who were taught with GeoGebra-assisted Reciprocal Teaching strategy were significantly higher than those of students who received conventional learning. Mathematical persistence of students taught with GeoGebra-assisted Reciprocal Teaching strategy was also significantly higher than of those taught with conventional learning.

    Full Text Available Energy storage systems (ESS play an important role in the performance of mining vehicles. A hybrid ESS combining both batteries (BTs and supercapacitors (SCs is one of the most promising solutions. As a case study, this paper discusses the optimal hybrid ESS sizing and energy management strategy (EMS of 14-ton underground load-haul-dump vehicles (LHDs. Three novel contributions are added to the relevant literature. First, a multi-objective optimization is formulated regarding energy consumption and the total cost of a hybrid ESS, which are the key factors of LHDs, and a battery capacity degradation model is used. During the process, dynamic programming (DP-based EMS is employed to obtain the optimal energy consumption and hybrid ESS power profiles. Second, a 10-year life cycle cost model of a hybrid ESS for LHDs is established to calculate the total cost, including capital cost, operating cost, and replacement cost. According to the optimization results, three solutions chosen from the Pareto front are compared comprehensively, and the optimal one is selected. Finally, the optimal and battery-only options are compared quantitatively using the same objectives, and the hybrid ESS is found to be a more economical and efficient option.

    Highlights: • A non-linear model regarding fuel economy and system durability of FCEV. • A two-step algorithm for a quasi-optimal solution to a multi-objective problem. • Optimal parameters for DP algorithm considering accuracy and calculating time. • Influences of FC power and battery capacity on system performance. - Abstract: A typical topology of a proton electrolyte membrane (PEM) fuel cell electric vehicle contains at least two power sources, a fuel cell system (FCS) and a lithium battery package. The FCS provides stationary power, and the battery delivers dynamic power. In this paper, we report on the multi-objective optimization problem of powertrain parameters for a pre-defined driving cycle regarding fuel economy and system durability. We introduce the dynamic model for the FCEV. We take into consideration equations not only for fuel economy but also for system durability. In addition, we define a multi-objective optimization problem, and find a quasi-optimal solution using a two-loop framework. In the inside loop, for each group of powertrain parameters, a global optimal energy management strategy based on dynamic programming (DP) is exploited. We optimize coefficients for the DP algorithm to reduce calculating time as well as to maintain accuracy. For the outside loop, we compare the results of all the groups with each other, and choose the Pareto optimal solution based on a compromise of fuel economy and system durability. Simulation results show that for a “China city bus typical cycle,” a battery capacity of 150 Ah and an FCS maximal net output power of 40 kW are optimal for the fuel economy and system durability of a fuel cell city bus.

    2018-05-01

    Full Text Available This study examined the student-centred teaching strategies of Mexican teachers by gender, grade level, and self-concept as an instructor. A conventional sample of 573 teachers from diverse school settings in the state of Yucatan in Mexico responded to a paper and pencil questionnaire. Results indicated, in general, that teachers prioritized classroom management and independent learning activities, in contrast with teaching strategies emphasized by policies and teacher´s training programs in the country, such as cooperative learning, differentiation, or promoting critical thinking. There were some gender and grade level differences. In general, female teachers promoted more independent activities than males. As expected, primary school teachers were more concerned with using differentiation teaching strategies than secondary education teachers, considering the greatest variance in younger students. Teachers self-concept had differential effects. Whilst self-efficacy feelings had no influence in the use of specific student-centred teaching strategies, high self-esteem teachers used more student-centred teaching strategies. The importance of asking teachers what they did, and how they felt as teachers was argued in light of results. Future research avenues regarding self-concept and teaching strategies are posited.

    2017-06-01

    Recent research indicates that using multimodal learning experiences can be effective in teaching mathematics. Using a social semiotic lens within a participationist framework, this paper reports on a professional learning collaboration with a primary school teacher designed to explore the use of metaphors and modalities in mathematics instruction. This video case study was conducted in a year 2 classroom over two terms, with the focus on building children's understanding of computational strategies. The findings revealed that the teacher was able to successfully plan both multimodal and multiple metaphor learning experiences that acted as semiotic resources to support the children's understanding of abstract mathematics. The study also led to implications for teaching when using multiple metaphors and multimodalities.

    2015-08-01

    Full Text Available This article is an analysis of the unique needs of returning service members at the college or university level that impact the teaching decisions made by instructors. The article also discusses the challenges that service members are individually addressing while acclimating themselves to their new environment of learning. With the reduction in forces occurring after the Iraq and Afghanistan wars, many higher level learning institutions are struggling to adequately meet the needs of returning veterans. In turn, veterans often find that the style of instruction and the general college-level universe are difficult to negotiate. The combination of these factors can often result in veteran students performing below expectation or leaving school without finishing. The article proposes a variety of ways to understand and address these challenges including the use of Scholarship of Teaching and Learning (SoTL strategies and characteristics.

    Nurse educators might be unknowingly excluding learners secondary to teaching practices. Universal design for instruction (UDI) prepares and delivers accessible content and learning environments for diverse learners; however, it is not well known in nursing education. The aim of the study was to examine the psychometric properties of the Inclusive Teaching Strategies in Nursing Education (ITSinNE) 55-item instrument. Confirmatory factor analysis was performed on a sample of 311 educators in prelicensure programs. The ITSinNE scales had good to adequate estimates of reliability. The exogenous model fit the sample and model-implied covariance matrix; however, the endogenous model was not a good fit. Further instrument development is required. Measuring factors influencing nurse educators' willingness to adopt UDI will enable intervention research to enhance professional development fostering content and environmental access for all learners.

    Full Text Available Institutions of higher learning across the nation are responding to political, economic, social and technological pressures to be more responsive to students' needs and more concerned about how well students are prepared to assume future societal roles. This study aimed to determine the methods and teaching strategies used by the PSU – CTE faculty members of Bayambang Campus, Bayambang, Pangasinan during the first semester of the school year 2013-2014. The descriptivecorrelational method of research was employed in this study where it involved the collection of pertinent data in order to answer questions concerning the current status of the subject of the study. Majority of the faculty members are females, they are master’s degree holders, have a permanent position with an academic rank of instructor, and most of the faculty members are graduate of SUCs. They also have high attitude toward teaching; generally, the faculty members perceived themselves to be often in using teaching approaches and teaching methods; and sometimes in using teaching techniques/styles, instructional support activities, and non-formal activities; and no significant relationships exist between the faculty members’ profile variables and their level of pedagogical approaches in teaching approaches, teaching methods, teaching techniques/styles, non-formal activities and instructional support activities. Teachers should be encouraged to pursue/finish higher education, likewise they should be motivated to conduct research studies like action researches as part of their functions, particularly along their area of specialization. Teachers should be encouraged to explore and view other effective teaching strategies and find more ways to entice other students challenge themselves to create their own strategies to use in the field and to become more global in perspective. The use computer technology can be an effective teaching strategy, especially when students are given

    Traditional ways of teaching in Higher Education are enhanced with adult-based approaches to learning within the curriculum. Adult-based learning enables students to take ownership of their own learning, working in independence using a holistic approach. Introducing creative activities promotes students to think in alternative ways to the traditional learning models. The study aimed to explore student midwives perceptions of a creative teaching method as a learning strategy. A qualitative design was used adopting a phenomenological approach to gain the lived experience of students within this learning culture. Purposive sampling was used to recruit student midwives (n=30). Individual interviews were conducted using semi-structured interviews with open-ended questions to gain subjective information. Data were transcribed and analyzed into useful and meaningful themes and emerging themes using Colaizzi's framework for analyzing qualitative data in a logical and systematic way. Over 500 meaningful statements were identified from the transcripts. Three key themes strongly emerged from the transcriptions. These included'meaningful learning','inspired to learn and achieve', and 'being connected'. A deep meaningful learning experience was found to be authentic in the context of theory and practice. Students were inspired to learn and achieve and positively highlighted the safe learning environment. The abilities of the facilitators were viewed positively in supporting student learning. This approach strengthened the relationships and social engagement with others in the peer group and the facilitators. On a less positive note, tensions and conflict were noted in group work and indirect negative comments about the approach from the teaching team. Incorporating creative teaching activities is a positive addition to the healthcare curriculum. Creativity is clearly an asset to the range of contemporary learning strategies. In doing so, higher education will continue to keep

    2010-05-01

    Increasingly, the geoscience user community expects modern IT capabilities to be available in service of their research and education activities, including the ability to easily access and process large remote sensing datasets via online portals such as GEON (www.geongrid.org) and OpenTopography (opentopography.org). However, serving such datasets via online data portals presents a number of challenges. In this talk, we will evaluate the pros and cons of alternative storage strategies for management and processing of such datasets using binary large object implementations (BLOBs) in database systems versus implementation in Hadoop files using the Hadoop Distributed File System (HDFS). The storage and I/O requirements for providing online access to large datasets dictate the need for declustering data across multiple disks, for capacity as well as bandwidth and response time performance. This requires partitioning larger files into a set of smaller files, and is accompanied by the concomitant requirement for managing large numbers of file. Storing these sub-files as blobs in a shared-nothing database implemented across a cluster provides the advantage that all the distributed storage management is done by the DBMS. Furthermore, subsetting and processing routines can be implemented as user-defined functions (UDFs) on these blobs and would run in parallel across the set of nodes in the cluster. On the other hand, there are both storage overheads and constraints, and software licensing dependencies created by such an implementation. Another approach is to store the files in an external filesystem with pointers to them from within database tables. The filesystem may be a regular UNIX filesystem, a parallel filesystem, or HDFS. In the HDFS case, HDFS would provide the file management capability, while the subsetting and processing routines would be implemented as Hadoop programs using the MapReduce model. Hadoop and its related software libraries are freely available

    In this paper, an optimization technique called peer enhanced teaching learning based optimization (PeTLBO) algorithm is used in multi-objective problem domain. The PeTLBO algorithm is parameter less so it reduced the computational burden. The proposed peer enhanced multi-objective based TLBO (PeMOTLBO) algorithm has been utilized to find a set of non-dominated optimal solutions [distributed generation (DG) location and sizing in distribution network]. The objectives considered are: real power loss and the voltage deviation subjected to voltage limits and maximum penetration level of DG in distribution network. Since the DG considered is capable of injecting real and reactive power to the distribution network the power factor is considered as 0.85 lead. The proposed peer enhanced multi-objective optimization technique provides different trade-off solutions in order to find the best compromise solution a fuzzy set theory approach has been used. The effectiveness of this proposed PeMOTLBO is tested on IEEE 33-bus and Indian 85-bus distribution system. The performance is validated with Pareto fronts and two performance metrics (C-metric and S-metric) by comparing with robust multi-objective technique called non-dominated sorting genetic algorithm-II and also with the basic TLBO.

    Full Text Available Harmony search (HS algorithm is an emerging population-based metaheuristic algorithm, which is inspired by the music improvisation process. The HS method has been developed rapidly and applied widely during the past decade. In this paper, an improved global harmony search algorithm, named harmony search based on teaching-learning (HSTL, is presented for high dimension complex optimization problems. In HSTL algorithm, four strategies (harmony memory consideration, teaching-learning strategy, local pitch adjusting, and random mutation are employed to maintain the proper balance between convergence and population diversity, and dynamic strategy is adopted to change the parameters. The proposed HSTL algorithm is investigated and compared with three other state-of-the-art HS optimization algorithms. Furthermore, to demonstrate the robustness and convergence, the success rate and convergence analysis is also studied. The experimental results of 31 complex benchmark functions demonstrate that the HSTL method has strong convergence and robustness and has better balance capacity of space exploration and local exploitation on high dimension complex optimization problems.

    Full Text Available This study aimed to examine the indirect teaching strategies adopted by a coach educator in terms of promoting student-coaches’ engagement in a positive and active learning environment. The participants were an expert coach educator and seven student-coaches from an academic coaching setting. A mix method approach was used to collect data. Whilst video-recording and participant observations were used to collect data from the lessons, focus groups were adopted to recall the perceptions of student-coaches. The results showed that indirect teaching strategies (i.e., asking questions, showing signs of autonomy by monitoring the pace at which they completed tasks and actively engaging in the search for solutions to tasks implemented by the coach educator promoted a supportive and challenging learning environment which, in turn, encouraged student-coaches to be more actively involved in the lessons. Additionally, the affective aspects of the relationship established with student-coaches (tone of voice, gestures, facial expressions, eye contact, physical contact and humor led them to feel confident in exposing their doubts and opinions, and in learning in a more autonomous manner. Moreover, the practical lessons proved to be crucial in helping student-coaches to reach broader and deeper forms of understanding by allowing the application of theory to coaching practice. In conclusion, this study reinforces the value of indirect teaching strategies to stimulate an active learning environment. It further highlights the value of practical learning environments to better prepare neophyte coaches for dealing with the complex and dynamic nature of their professional reality.

    2011-12-01

    Many countries rely on immigrants for population growth and to maintain a skilled workforce. However, many such immigrants face literacy-related barriers to success in education and in the labour force. This meta-analysis reviews experimental and quasi-experimental studies to examine strategies for teaching English literacy to immigrant students. Following an exhaustive and systematic search for studies meeting pre-determined inclusion criteria, two researchers independently extracted data from 26 English as a Second Language (ESL) studies involving 3,150 participants. These participants consisted of ESL immigrant students in kindergarten through grade 6 who were exposed to English literacy instructional interventions. Measured outcomes were reading and writing. Mean effect sizes vary from small to large, depending on instructional interventions and outcome constructs. Across several different grade levels, settings, and methodological features, pedagogical strategies used in teaching ESL to immigrant students are associated with increased competence in reading and writing. Collaborative reading interventions, in which peers engage in oral interaction and cooperatively negotiate meaning and a shared understanding of texts, produced larger effects than systematic phonics instruction and multimedia-assisted reading interventions. The results show that the pedagogical strategies examined in this meta-analysis produced statistically significant benefits for students in all grade levels. The findings also show that students from low socio-economic status (SES) background benefit from ESL literacy interventions. However, significant heterogeneity was found in each subset. Educators and policy makers are encouraged to consider specific school contexts when making decisions about optimal pedagogical strategies. It is possible that contextual factors as well as ESL learner characteristics may influence the effectiveness of these strategies. To ensure literacy acquisition

    A challenge for urologic nurses and nurse educators is how to present information to staff, students, and patients in a way that will capture their interest and engage them in the learning process. The use of adult-learning principles and innovative teaching strategies can make the learning experience dynamic, and encourage learners to take a more active role in their own learning. Games are a creative, fun, and interactive way to assist in the emphasis, review, reinforcement, and retention of information for urology nurses.

  1. Critical Thinking in Critical Care: Five Strategies to Improve Teaching and Learning in the Intensive Care Unit.

    Science.gov (United States)

    Hayes, Margaret M; Chatterjee, Souvik; Schwartzstein, Richard M

    2017-04-01

    Critical thinking, the capacity to be deliberate about thinking, is increasingly the focus of undergraduate medical education, but is not commonly addressed in graduate medical education. Without critical thinking, physicians, and particularly residents, are prone to cognitive errors, which can lead to diagnostic errors, especially in a high-stakes environment such as the intensive care unit. Although challenging, critical thinking skills can be taught. At this time, there is a paucity of data to support an educational gold standard for teaching critical thinking, but we believe that five strategies, routed in cognitive theory and our personal teaching experiences, provide an effective framework to teach critical thinking in the intensive care unit. The five strategies are: make the thinking process explicit by helping learners understand that the brain uses two cognitive processes: type 1, an intuitive pattern-recognizing process, and type 2, an analytic process; discuss cognitive biases, such as premature closure, and teach residents to minimize biases by expressing uncertainty and keeping differentials broad; model and teach inductive reasoning by utilizing concept and mechanism maps and explicitly teach how this reasoning differs from the more commonly used hypothetico-deductive reasoning; use questions to stimulate critical thinking: "how" or "why" questions can be used to coach trainees and to uncover their thought processes; and assess and provide feedback on learner's critical thinking. We believe these five strategies provide practical approaches for teaching critical thinking in the intensive care unit.

Department of Community Medicine at Fatima Memorial College of Medicine and Dentistry from July to November 2010. A probability technique of simple random sampling was used to collect 63 students from the third and fourth year MBBS who were randomly distributed in five sub-groups. They were variously ascribed the roles of obsceners, participants and helpers. A questionnaire was distributed to collect student's responses. The data was analyzed on SPSS version 17 to compare the responses. Chi-square test was applied and p-value was fixed at andragogy (p = 0.005) and 48 (76.2%) said that it provoked critical thinking about the subject (p = 0.038). Fifty-four students (85.7%) admitted that their attention span was better in role-plays as compared to lectures (p = 0.047). Role-plays were well accepted by the students as an effective teaching methodology and can be incorporated as a part of teaching strategies in Community Medicine.

    Full Text Available Universities across the world are undergoing rapid, and often significant, change to compete in an increasingly global environment. The Bologna process of higher education reforms has had its impact not only across Europe but globally given the pressure on universities to compete and to provide students with transferable qualifications in the quest for borderless education. As part of the process universities have been encouraged to differentiate themselves, particularly in terms of being research focused or teaching focus. As a result, many universities are putting in place strategies to boost their research output. With a view to contributing to the discussions by the International Advisory Board of the Department of Public Administration at Babes- Bolyai University, this paper overviews some of the strategies put in place by Australian Universities in order to improve the research output of their academic staff and provides some university marketing based suggestions for Babes-Bolyai University.

    Full Text Available This research reports on the findings regarding the perceptions of teachers towards creating space for the use of code switching as a teaching strategy in Afrikaans learning and teaching in the isiXhosa-speaking environments of the Transkei region. The aim of this investigation was to establish whether or not code switching can be used as a teaching strategy. A sample of 13 teachers from 12 schools was purposefully selected. A qualitative approach was used. Interviews and semi-structured questionnaires were used for data collection. The teachers admitted that they code switch during Afrikaans classes. It also transpired that teachers perceived code switching as the best way to facilitate understanding. The recommendations postulate a gradual move from a high tolerance of code switching in the lower classes to a low tolerance thereof in higher classes.

  5. Teaching strategies and conceptual change in a professional development program for science teachers of K--8

    Science.gov (United States)

    Shen, Ji

    This case study investigates two consecutive science courses for teachers of K-8 in a professional development program at Washington University. It aims (1) to trace the processes of the teachers' conceptual change; (2) to analyze the teaching strategies by course instructors; and (3) to try to establish possible links between the two. To achieve this goal, I build a modeling theory to account for the observations. The main body of the study consists of four sub-cases. The first two cases instantiate the elements of the modeling theory. The opening case of balance shows that learning tools and task structures shape the learning outcome, and discusses cycles of modeling. The case also delineates the strategy that the instructors employed---moving from concrete experience to abstract explanation. The second case of buoyancy demonstrates that the modeling theory is able to explain the origins and forming mechanism of the alternative conceptions held by the teachers. It also shows that the teaching strategies of using alternative conceptions, applying analogies and following a logical sequence helped the teachers build new models. The last two cases demonstrate the ways of improving the competence of modelers. The third case of physical models emphasizes the metacognition of the learner who builds models. It illustrates that teachers' level of self-awareness in learning is increased when the models are physical. It shows that the creativity of modeling is rooted in agency, curiosity, communicability, and confidence, and that a chain of transformation among models is the key of systematizing and forming knowledge. The last case of frames of reference tries to answer the question "what is the justification of models if there are alternatives?" The teachers employed different forms of justification which relied heavily on common sense, authority, relativism, and pragmatism, all of which are not rational. While discussing both the positive and negative traits of these

    Bamberger, Yael M.; Cahill, Clara S.

    2013-04-01

    This study deals with engineering education in the middle-school level. Its focus is instructors' concerns in teaching design, as well as scaffolding strategies that can help teachers deal with these concerns. Through participatory action research, nine instructors engaged in a process of development and instruction of a curriculum about energy along with engineering design. A 50-h curriculum was piloted during a summer camp for 38 middle-school students. Data was collected through instructors' materials: observation field notes, daily reflections and post-camp discussions. In addition, students' artifacts and planning graphical models were collected in order to explore how instructors' concerns were aligned with students' learning. Findings indicate three main tensions that reflect instructors' main concerns: how to provide sufficient scaffolding yet encourage creativity, how to scaffold hands-on experiences that promote mindful planning, and how to scaffold students' modeling practices. Pedagogical strategies for teaching design that developed through this work are described, as well as the ways they address the National Research Council (A framework for K-12 science education: practices, crosscutting concepts, and core ideas. National Academies Press, Washington, DC, 2011) core ideas of engineering education and the International Technological Literacy standards (ITEA in Standards for technological literacy, 3rd edn.

    Full Text Available Some research has argued that effective teachers significantly influence students’ performance. However, becoming effective teachers are not easy because they have to apply some strategies of effective teaching. For that reason, this paper intends to investigate whether  teachers from three Islamic Senior High Schools in South Jakarta practice effective teaching strategies. These schools have been considered good due to  the high mean score of English subject in Ujian Nasional. The framework of effective teaching follows the model developed by Creemers and Kyriakides, which relate teacher behavior in the classroom and student achievement . The framework consists of orientation, structuring, questioning, teaching modeling, applications, teacher role in making classroom a learning environment, management of time, and classroom assessment.

    2017-12-01

    Full Text Available English in Tanzania is taught as one of the major subjects at Advanced Certificate of Secondary School Education (ACSE. This paper explores the strategies employed by teachers in implementing the ACSE curriculum. The curriculum requires that the subject be taught using the competence based approach where learner-centred strategies are emphasized. The study employed mixed methods and descriptive design. Purposive sampling was used to get schools and teachers because it was only schools that had English as a major subject in the municipality that were selected. The findings reveal that the teacher-centerd strategies dominate the curriculum implementation as opposed to learner-centerd ones as required by the curriculum. The paper therefore recommends that teachers in Iringa municipality be oriented on the learner-centred strategies in the implementation of English at ACSE. It is further recommended that since oral language skills form a large part of the curriculum, these skills be assessed at both school and national based assessments if they are to be taught and learnt. This is because no teacher can waste time teaching what is not assessed and no student can take trouble to learn what is not assessed.

    Inclusive education policies have led to a worldwide increase in the number of teaching assistants (TAs) working in mainstream schools. TAs have a large amount of responsibility for supporting children with special educational needs and disabilities (SEND), a role which by default has become instructional in practice, and for which training and preparation are rarely adequate. While there is some research into the nature of TAs' interactions with pupils and the strategies they use which are helpful for children's learning, TAs' perspectives on their own classroom practice have yet to be explored. To explore TAs' perceptions about their use of inclusive pedagogical strategies. The study involved eleven TAs in two mainstream primary schools. The TAs were interviewed face to face to explore their views about inclusive pedagogical strategies. The data were analysed using thematic analysis. TAs were clear about the strategies they use to offer emotional and relational support to children. There were some gaps, however, in their knowledge about how children learn, specifically in terms of transferring responsibility for learning onto children. The study advances understanding of scaffolding from a TA perspective and highlights the importance of training TAs in scaffolding theory. © 2017 The British Psychological Society.

  13. Professional development strategies for teaching urban biology teachers to use concept maps effectively

    Science.gov (United States)

    McGregor Petgrave, Dahlia M.

    Many teachers are not adequately prepared to help urban students who have trouble understanding conceptual ideas in biology because these students have little connection to the natural world. This study explored potential professional development strategies to help urban biology teachers use concept maps effectively with various topics in the biology curriculum. A grounded theory approach was used to develop a substantive professional development model for urban biology teachers. Qualitative data were collected through 16 semi-structured interviews of professional developers experienced in working with concept maps in the urban context. An anonymous online survey was used to collect quantitative data from 56 professional developers and teachers to support the qualitative data. The participants were from New York City, recruited through the NY Biology-Chemistry Professional Development Mentor Network and the NY Biology Teachers' Association. According to the participants, map construction, classroom applications, lesson planning, action research, follow-up workshops, and the creation of learning communities are the most effective professional development strategies. The interviewees also proposed English language learning strategies such as picture maps, native word maps, and content reading materials with underlined words. This study contributes to social change by providing a professional development model to use in planning workshops for urban teachers. Urban teachers improve their own conceptual understanding of biology while learning how to implement concept mapping strategies in the classroom. Students whose teachers are better prepared to teach biology in a conceptual manner have the potential of growing into more scientifically literate citizens.

    Full Text Available Background: Case-based education has a long history in the disciplines of education, business, law and the health professions. Research suggests that students who learn via a case-based method have advanced critical thinking skills and a greater ability for application of knowledge in practice. In medical education, case-based methodology is widely used to facilitate knowledge transfer from theoretical knowledge to application in patient care. Nursing education has also adopted case-based methodology to enhance learner outcomes and critical thinking.Objectives: The objectives of the study was to describe a decentralised nursing management education programme located in Durban, South Africa and describe the perceptions of nursing faculty facilitators regarding implementation of this teaching method.Method: Data was collected through the use of one-on-one interviews and also focus groups amongst the fifteen facilitators who were using a case-based curriculum to teach the programme content. The average facilitator was female, between 41 and 50 years of age, working part-time, educated with a baccalaureate degree, working as a professional nurse for between 11 and 20 years; slightly more than half had worked as a facilitator for three or more years.Results: The facilitators identified themes related to the student learners, the learning environment, and strengths and challenges of using facilitation to teach the content through cases. Decentralised nursing management educational programmes can meet the needs of nurses who are located in remote areas which are characterised by poor transportation patterns and limited resources and have great need for quality healthcare services.Conclusion: Nursing faculty facilitators need knowledgeable and accessible contact with centrally based full-time nursing faculty in order to promote high quality educational programmes.

    This year long, qualitative, case study examines two, experienced, high school, biology teachers as they facilitated nature of science (NOS) understandings in their classrooms. This study explored three research questions: (1) In what ways do experienced teachers' conceptions of NOS evolve over one full year as a result of participating in a course that explicitly address NOS teaching and learning? (2) In what ways do experienced teachers' pedagogical practices evolve over one full year as a result of participating in a course that explicitly address NOS teaching and learning?, and (3) What are the challenges facing experienced teachers in their attempts to implement NOS understandings in their science, high school classrooms? This study was conducted in two parts. In Part I (fall 2004 semester), the participants were enrolled in a graduate course titled, Teaching the Nature of Science , where they were introduced to: (1) NOS, (2) a strategy, the Model for Teaching NOS (MTNOS), which helped them facilitate teaching NOS understandings through inquiry-based activities, and (3) participated in "real" science activities that reinforced their conceptions of NOS. In Part II (spring 2005 semester), classroom observations were made to uncover how these teachers implemented inquiry-based activities emphasizing NOS understanding in their classrooms. Their conceptions of NOS were measured using the Views of the Nature of Science questionnaire. Results demonstrated that each teacher's conceptions of NOS shifted slightly during course the study, but, for one, this was not a permanent shift. Over the year, one teacher's pedagogical practices changed to include inquiry-based lessons using MTNOS; the other, although very amenable to using prepared inquiry-based lessons, did not change her pedagogical practices. Both reported similar challenges while facilitating NOS understanding. The most significant challenges included: (1) time management; (2) the perception that NOS was a

    As of 2006, the Accreditation Council for Graduate Medical Education had defined six "core competencies" of residency education: interpersonal communication skills, medical knowledge, patient care, professionalism, practice-based learning and improvement, and systems-based practice. Objective structured clinical examinations using standardized patients are becoming effective educational tools, and the authors developed a novel use of the examinations in plastic surgery residency education that assesses all six competencies. Six plastic surgery residents, two each from postgraduate years 4, 5, and 6, participated in the plastic surgery-specific objective structured clinical examination that focused on melanoma. The examination included a 30-minute videotaped encounter with a standardized patient actor and a postencounter written exercise. The residents were scored on their performance in all six core competencies by the standardized patients and faculty experts on a three-point scale (1 = novice, 2 = moderately skilled, and 3 = proficient). Resident performance was averaged for each postgraduate year, stratified according to core competency, and scored from a total of 100 percent. Residents overall scored well in interpersonal communications skills (84 percent), patient care (83 percent), professionalism (86 percent), and practice-based learning (84 percent). Scores in medical knowledge showed a positive correlation with level of training (86 percent). All residents scored comparatively lower in systems-based practice (65 percent). The residents reported unanimously that the objective structured clinical examination was realistic and educational. The objective structured clinical examination provided comprehensive and meaningful feedback and identified areas of strengths and weakness for the residents and for the teaching program. The examination is an effective assessment tool for the core competencies and a valuable adjunct to residency training.

    Full Text Available Subject of Research. The paper presents a relatively simple method to develop interactive computer models of physical systems without computer programming skills or automatic generation of the numerical computer code for the complex physical systems. Developed computer models are available over the Internet for educational purposes and can be edited by users in an unlimited number of possibilities. An applicability of computer simulations for the massive open individualized teaching and an organization of undergraduate research are also discussed. Method. The presented approach employs an original physical object-oriented modeling method, which is an extension of object-oriented programming ideas to tasks of developing simulations of the complex physical systems. In this framework, a computer model of the physical system is constructed as a set of interconnected computer objects simulating the system components: particles and fields. Interactions between the system components are described by self-adapting algorithms that are specified during the model initiation stage and are set according to either the classical or relativistic approach. The utilized technique requires neither a priori knowledge regarding an evolution of the physical system nor a formulation of differential equations describing the physical system. Main Results. Testing of the numerical implementation and an accuracy of the algorithms was performed with the use of benchmarks with the known analytical solutions. The developed method - a physical reality constructor - has provided an opportunity to assemble a series of computer models to demonstrate physical phenomena studied in the high school and university mechanic courses. More than 150 original interactive models were included into the collections of multi-level multimedia resources to support teaching of the mechanics. The physical reality constructor was successfully tested to serve as a test bed for the independent

    Directory of Open Access Journals (Sweden)

    Silvia Augusta Albert Bachur

    2016-07-01

    Full Text Available This article aims at presenting how current theoretical advances on Text Linguistics in its sociocognitive and interactional perspective, by approaching the concepts of cohesion, coherence, and referentiation, may contribute to the pedagogical practice regarding the teaching and learning of writing vis-à-vis the development of writing proficiency. Hence, cohesion and coherence are considered the criteria for textualization, and both their reciprocity and their mutual determination in the referentiation process are here acknowledged. From this point view, the construction of cohesion and coherence is a dynamic process that occurs via inferences and cognitive devices to which the linguistic marks, the speakers’ interaction, and the context contribute. Accordingly, a selection of nominal forms in the building of representations of discourse objects is to be highlighted and related to the project of saying enounced by the herald of college entrance essays. The hypothesis is thus that, by constructing representations of discourse objects, referentiation establishes a groundwork for text structuring and provides hints to produce meaning in writing. The main studies this article is grounded on are Koch (2006, Marcuschi (2006; 2007; 2008, Cavalcante et al. (2010, and Bentes (2012.

    2007-01-01

    The purpose of this article is to describe the innovation-decision process teaching strategy (I-DPTS) based on the model of diffusion of innovations [Rogers, E. M. (2003). Diffusion of innovations (5th ed.). New York: Free Press]. A goal of baccalaureate nursing education is to develop competencies required for evidence-based practice. Such practice merges clinician expertise, patient preferences, and critical evaluation of the literature to improve patient outcomes and reduce health care costs [Melnyk, B. M. (2005). A primer on evidence-based practice. Paper presented at the Purdue School of Nursing Seventh Annual Helen R. Johnson Leadership Conference, West Lafayette, IN]. Several strategies to promote evidence-based practice have appeared in the literature. However, when they are examined in light of the innovation-decision process (Rogers, 2003), they do not address all the essential steps for adoption to occur. The I-DPTS allows students to achieve competencies necessary to overcome barriers associated with implementing best practices. This strategy was successfully implemented in a senior-level introductory nursing research class. Community representatives identified practice issues that could be addressed by student groups. After conducting a search of the literature, students analyzed the evidence, determined best practice based on the evidence, and developed a policy for implementation in clinical settings. At course end, representatives were invited to attend oral and poster presentations. Use of the I-DPTS better prepares students to implement best practice as they embark on their professional careers.

    2016-03-01

    Peer coaching has been associated with positive effects on learning. Specifically, these associations have been explored in complex healthcare professions. A social theory of learning has been proposed as a key component of the utility of peer coaching. Further, within the peer coaching model, assessment has been considered as an important driver. Empirical support for these dimensions of the model is lacking. To quantify assessment achievements and explore emergent attitudes and beliefs about learning related to a specific peer coaching model with integrated assessment. A longitudinal study based in a UK Higher Education Institute recorded assessment achievements and surveyed attitudes and beliefs in consecutive Year 1 undergraduate (physiotherapy) students (n = 560) between 2002 and 2012. A 6% improvement in academic achievement was demonstrated following the introduction of a peer coaching learning model. This was increased by a further 5% following the implementation of an integrated assessment. The improvement related to an overall averaged increase of one marking band. Students valued the strategy, and themes relating to the importance of social learning emerged from survey data. Peer coaching is an evidence-based teaching and learning strategy which can facilitate learning in complex subject areas. The strategy is underpinned by social learning theory which is supported by emergent student-reported attitudes.

  5. A Lakatosian Conceptual Change Teaching Strategy Based on Student Ability to Build Models with Varying Degrees of Conceptual Understanding of Chemical Equilibrium

    Science.gov (United States)

    Niaz, M.

    The main objective of this study is to construct a Lakatosian teaching strategy that can facilitate conceptual change in students'' understanding of chemical equilibrium. The strategy is based on the premise that cognitive conflicts must have been engendered by the students themselves in trying to cope with different problem solving strategies. Results obtained (based on Venezuelan freshman students) show that the performance of the experimental group of students was generally better (especially on the immediate post tests) than that of the control group. It is concluded that a conceptual change teaching strategy must take into consideration the following aspects: a) core beliefs of the students in the topic (cf. ''hard core'', Lakatos 1970); b) exploration of the relationship between core beliefs and student alternative conceptions (misconceptions); c) cognitive complexity of the core belief can be broken down into a series of related and probing questions; d) students resist changes in their core beliefs by postulating ''auxiliary hypotheses'' in order to resolve their contradictions; e) students'' responses based on their alternative conceptions must be considered not as wrong, but rather as models, perhaps in the same sense as used by scientists to break the complexity of a problem; and f) students'' misconceptions be considered as alternative conceptions (theories) that compete with the present scientific theories and at times recapitulate theories scientists held in the past.

    Full Text Available Optimization of the control strategy plays an important role in improving the performance of electric vehicles. In order to improve the braking stability and recover the braking energy, a multi-objective genetic algorithm is applied to optimize the key parameters in the control strategy of electric vehicle electro-hydraulic composite braking system. Various limitations are considered in the optimization process, and the optimization results are verified by a software simulation platform of electric vehicle regenerative braking system in typical brake conditions. The results show that optimization objectives achieved a good astringency, and the optimized control strategy can increase the brake energy recovery effectively under the condition of ensuring the braking stability.

  7. Orbital prefrontal cortex is required for object-in-place scene memory but not performance of a strategy implementation task.

    The orbital prefrontal cortex is thought to be involved in behavioral flexibility in primates, and human neuroimaging studies have identified orbital prefrontal activation during episodic memory encoding. The goal of the present study was to ascertain whether deficits in strategy implementation and episodic memory that occur after ablation of the entire prefrontal cortex can be ascribed to damage to the orbital prefrontal cortex. Rhesus monkeys were preoperatively trained on two behavioral tasks, the performance of both of which is severely impaired by the disconnection of frontal cortex from inferotemporal cortex. In the strategy implementation task, monkeys were required to learn about two categories of objects, each associated with a different strategy that had to be performed to obtain food reward. The different strategies had to be applied flexibly to optimize the rate of reward delivery. In the scene memory task, monkeys learned 20 new object-in-place discrimination problems in each session. Monkeys were tested on both tasks before and after bilateral ablation of orbital prefrontal cortex. These lesions impaired new scene learning but had no effect on strategy implementation. This finding supports a role for the orbital prefrontal cortex in memory but places limits on the involvement of orbital prefrontal cortex in the representation and implementation of behavioral goals and strategies.

    It is not known whether, during the course of aging, changes occur in the motor strategies used by the CNS for lifting objects of different weights. Here, we analyzed the kinematics of object-lifting in two different healthy groups (young and elderly people) plus one well-known deafferented patient (GL). The task was to reach and lift onto a shelf an opaque cylindrical object with changing weight. The movements of the hand and object were recorded with electromagnetic sensors. In an ecological context (i.e. no instruction was given about movement speed), we found that younger participants, elderly people and GL did not all move at the same speed and that, surprisingly, elder people are faster. We also observed that the lifting trajectories were constant for both the elderly and the deafferented patient while younger participants raised their hand higher when the object weighed more. It appears that, depending on age and on available proprioceptive information, the CNS uses different strategies of lifting. We suggest that elder people tend to optimize their feedforward control in order to compensate for less functional afferent feedback, perhaps to optimize movement time and energy expenditure at the expense of high precision. In the case of complete loss of proprioceptive input, however, compensation follows a different strategy as suggested by GL's behavior who moved more slowly compared to both our younger and older participants.

    Full Text Available The primary purpose of this multiple case study is to explore teachers’ and learners’ perceptions of motivational teaching strategies. The data were obtained from two schools in a small town in West Sumatra, Indonesia; one is from an international standard high school and the other is from a local high school. This study is underpinned by Dornyei's (2001 work on motivational teaching practice which consists of four phases on how a teacher motivates students in a language learning classroom, namely: creating motivational components, generating students’ motivation, maintaining motivation, and encouraging positive retrospective self-evaluation. This qualitative case study is intended to contextualise the research within the real life environment of an Indonesian secondary class- room (Yin, 2003. The findings indicate that there are two groups of motivational components. The first is the teachers’ rapport with students, including the encouragement given to students and the building of trust and respect with the students. The second relates to the teachers’ planning decisions such as the selection of classroom activities, the way feedback is given, the management of the classroom, and the choice of learning resources.

    Promoting a scientific activity of research to students of a graduation program as a reflexive tool of teacher and formative practice of necessary activities to construction of a research in medical education. Graduation students of surgery at UFRJ did a research, randomly interviewing a population of medical teachers who acts at Medicine Universities of Rio de Janeiro. The study was structured in three steps: definition of the investigative content; realization of 150 interviews before field research and discussion about the results. The majority of interviewees (85%) assert to know the recent trends of education, but when they express their thoughts they leave doubts about the real knowledge of the subject. The expositive classes were used by 90% of the interviewees; only 10% of them utilized strategies of teaching to transmit the contents. Just 52% of the doctors said that they had already heard about the Resolution CNE/CES N° 4/2001. The teaching with research challenged the students as investigators preparing them to the research and construction of the necessary scientific attitudes in the graduation and assisting them in solving the investigated problem. The results highlighted that the found peaces of information in the research were not accurate to feature a real dimension of the update, showing that it is recommended new studies.

    2013-09-12

    Questions have long been used as a teaching tool by teachers and preceptors to assess students' knowledge, promote comprehension, and stimulate critical thinking. Well-crafted questions lead to new insights, generate discussion, and promote the comprehensive exploration of subject matter. Poorly constructed questions can stifle learning by creating confusion, intimidating students, and limiting creative thinking. Teachers most often ask lower-order, convergent questions that rely on students' factual recall of prior knowledge rather than asking higher-order, divergent questions that promote deep thinking, requiring students to analyze and evaluate concepts. This review summarizes the taxonomy of questions, provides strategies for formulating effective questions, and explores practical considerations to enhance student engagement and promote critical thinking. These concepts can be applied in the classroom and in experiential learning environments.

    Full Text Available The emergence of new technologies in education area is changing the way of organizing the educational processes. Teachers are not unrelated to these changes and must employ new strategies to adapt their teaching methods to the new circumstances. One of these adaptations is framed in the virtual learning, where the learning management systems have been revealed as a very effective means within the learning process. In this paper we try to provide teachers in engineering schools how to use in an appropriate way the different technological tools that are present in a virtual platform. Thus, in the experimental framework we show the results outcomes in the analysis of two data samples obtained before and after the implementation of the European Higher Education Area, that would be extrapolated for its innovative application to the learning techniques.

    Full Text Available Learning motivation represents one of the most importantpredictors of academic achievement in higher education. In this empirical study, we have implemented a formative program to improve the university students’ academic achievement and their intrinsic learning motivation. To fully use their intellectual potential, students were treated according to their learning style, throughout one academic year. When we considered the within subject design, both intrinsic motivation and academic achievement significantly increased at the end of the study. Only intrinsic motivation proved to be significantly higher for the between subject comparison. Because our formative program proved to have a significant impact on students’ learning motivation, we recommend the differentiated teaching strategies to improve the academic achievement in higher education.

  15. Efficient Dynamic Adaptation Strategies for Object Tracking Tree in Wireless Sensor Network

    Directory of Open Access Journals (Sweden)

    CHEN, M.

    2012-12-01

    Full Text Available Most object tracking trees are established using the predefined mobility profile. However, when the real object's movement behaviors and query rates are different from the predefined mobility profile and query rates, the update cost and query cost of object tracking tree may increase. To upgrade the object tracking tree, the sink needs to send very large messages to collect the real movement information from the network, introducing a very large message overhead, which is referred to as adaptation cost. The Sub Root Message-Tree Adaptive procedure was proposed to dynamically collect the real movement information under the sub-tree and reconstruct the sub-tree to provide good performance based on the collected information. The simulation results indicates that the Sub Root Message-Tree Adaptive procedure is sufficient to achieve good total cost and lower adaptation cost.

    In nursing education, the traditional lecture and direct demonstration teaching method cannot cultivate the various skills that nursing students need. How to choose a more scientific and rational teaching method is a common concern for nursing educators worldwide. To investigate the basis for selecting teaching methods among nursing teachers in mainland China, the factors affecting the selection of different teaching methods, and the application of different teaching methods in theoretical and skill-based nursing courses. Questionnaire survey. Seventy one nursing colleges from 28 provincial-level administrative regions in mainland China. Following the principle of voluntary informed consent, 262 nursing teachers were randomly selected through a nursing education network platform and a conference platform. The questionnaire contents included the basis for and the factors influencing the selection of nursing teaching methods, the participants' common teaching methods, and the teaching experience of the surveyed nursing teachers. The questionnaires were distributed through the network or conference platform, and the data were analyzed by SPSS 17.0 software. The surveyed nursing teachers selected teaching methods mainly based on the characteristics of the teaching content, the characteristics of the students, and their previous teaching experiences. The factors affecting the selection of teaching methods mainly included large class sizes, limited class time, and limited examination formats. The surveyed nursing teachers primarily used lectures to teach theory courses and the direct demonstration method to teach skills courses, and the application frequencies of these two teaching methods were significantly higher than those of other teaching methods (P=0.000). More attention should be paid to the selection of nursing teaching methods. Every teacher should strategically choose teaching methods before each lesson, and nursing education training focused on selecting

    With environmental awareness in the societies of today, political steering documents emphasize that all education should include sustainable development. But it seems to be others competing ideals for teaching physics, or why do the physics teachers teach as they do? Physics teachers in secondary school in Sweden have generally, been focused on facts and a strong link with scientific theories and concepts. In general, the curriculum sway the teaching, a standard text book in physics is used, the teaching is organized according to the book and the teacher deals with and demonstrates typical tasks on the whiteboard and group work is common for special issues related to tasks from the textbook or elaborating. The aim with this study is to analyze why physics teachers in upper secondary school choose to teach energy as they do. Data emerging from a questionnaire focused on indicators of the teachers' cultural and economic assets, or capital, according to the work of Pierre Bourdieu's sociology. Especially his concept on life styles and habitus provide a tool for analysis. We focus on physics teachers' positions in the social space, dispositions and standpoints towards the ideal way to teach physics in upper secondary school (n = 268). Our response rate is 29 % and due to the low response rate a non response bias analysis was made. In our analysis we primarily sought for groups, with a cluster analysis based on the teaching practice, revealed common features for both what and how they teach and three different teaching types emerged. Then we reconstructed the group habitus of the teachers by analyzing dispositions and standpoints and related those to the specific polarization of sacred values, that is struggles about the natural order (doxa) in the social space of science education, which is a part of and has boundaries to dominating fields like the natural sciences and the political fields (curriculum etc.). Three teacher-groups' habituses are described and analyzed

First, the system is able to perform long action sequences which......, although the grasping attempts not being always successful, can recover from mistakes and more importantly, is able to evaluate the success of the grasps autonomously by haptic feedback (i.e., by a force torque sensor at the wrist and proprioceptive information about the distance of the gripper after...... a gasping attempt). Such labelled data is then used for improving the initially hard-wired algorithm by learning. Moreover, the grasping behaviour has been used in a cognitive system to trigger higher level processes such as object learning and learning of object specific grasping....

    2006-08-01

    There are currently three different game strategies originated in economics: (1) Cooperative games (Pareto front), (2) Competitive games (Nash game) and (3) Hierarchical games (Stackelberg game). Each game achieves different equilibria with different performance, and their players play different roles in the games. Here, we introduced game concept into aerodynamic design, and combined it with adjoint method to solve multi-criteria aerodynamic optimization problems. The performance distinction of the equilibria of these three game strategies was investigated by numerical experiments. We computed Pareto front, Nash and Stackelberg equilibria of the same optimization problem with two conflicting and hierarchical targets under different parameterizations by using the deterministic optimization method. The numerical results show clearly that all the equilibria solutions are inferior to the Pareto front. Non-dominated Pareto front solutions are obtained, however the CPU cost to capture a set of solutions makes the Pareto front an expensive tool to the designer.

    The purpose of this study was to investigate the views of medical students and residents regarding the practice of professionalism, their perceived challenges, and ideas for the development of a new curriculum in medical professionalism. Data were collected from four focus groups comprised of 27 residents and medical students recruited from the University of South Florida Morsani School of Medicine and Residency Programs between January and March 2012. A questioning protocol was used to guide the focus group discussion. Data were transcribed for thematic analysis. Learners expressed beliefs regarding key attributes of professional behaviors, factors perceived to be associated with lapses of professional behavior, skills that need to be taught, and strategies to teach professionalism from the learners' perspective. Learners perceived that the values of professionalism are often disconnected from the reality evidenced in clinical training due to a myriad of personal and contextual challenges. Residents and students need help in negotiating some of the challenges to medical professionalism that are encountered in clinical settings. We recommend a learner's centered model of curriculum development in medical professionalism that takes into consideration perceived challenges and strategies for modeling and reinforcing medical professionalism.

    This paper presents a flexible control technique for connection of DG (distributed generation) resources to distribution networks, especially during ride-through on faulty grid. This strategy is derived from the abc/{alpha}{beta} and {alpha}{beta}/dq transformations of the ac system variables. The active and reactive currents injected by the DG source are controlled in the synchronously rotating orthogonal dq reference frame. The transformed variables are used to control the VSI (voltage source inverter) which connects the DG to the distribution network. Using a P.L.L. (phase locked loop) in circuit of proposed control technique, the angle of positive sequence has been detected, in order to synchronize the currents to the distribution network. The proposed control technique has the capability of providing active and reactive powers and harmonic currents to nonlinear loads with a fast dynamic response. Simulation results and mathematical analysis have been completed in order to achieve a reduced THD (total harmonic distortion), increased power factor and compensated load's active and reactive powers. The analyses show the high performance of this control strategy in DG applications in comparison with other existing strategies. (author)

    1984-10-01

    Full Text Available The problem of systematic derivation of a quasi-dynamic optimal control strategy for a non-linear dynamic process based upon a non-quadratic objective function is investigated. The wellknown LQG-control algorithm does not lead to an optimal solution when the process disturbances have non-zero mean. The relationships between the proposed control algorithm and LQG-control are presented. The problem of how to constrain process variables by means of 'penalty' - terms in the objective function is dealt with separately.

  4. Using constructivist teaching strategies in high school science classrooms to cultivate positive attitudes toward science

    Heron, Lory Elen

    This study investigated the premise that the use of constructivist teaching strategies (independent variable) in high school science classrooms can cultivate positive attitudes toward science (dependent variable) in high school students. Data regarding the relationship between the use of constructivist strategies and change in student attitude toward science were collected using the Science Attitude Assessment Tool (SAAT) (Heron & Beauchamp, 1996). The format of this study used the pre-test, post-test, control group-experimental group design. The subjects in the study were high school students enrolled in biology, chemistry, or environmental science courses in two high schools in the western United States. Ten teachers and twenty-eight classes, involving a total of 249 students participated in the study. Six experimental group teachers and four control group teachers were each observed an average of six times using the Science Observation Guide (Chapman, 1995) to measure the frequency of observed constructivist behaviors. The mean for the control group teachers was 12.89 and the mean for experimental group teachers was 20.67; F(1, 8) = 16.2, p =.004, revealing teaching behaviors differed significantly between the two groups. After a four month experimental period, the pre-test and post-test SAAT scores were analyzed. Students received a score for their difference in positive attitude toward science. The null hypothesis stating there would be no change in attitude toward science as a subject, between students exposed to constructivist strategies, and students not exposed to constructivist strategies was rejected F(1, 247) = 8.04, p =.005. The control group had a generally higher reported grade in their last science class than the experimental group, yet the control group attitude toward science became more negative (-1.18) while attitude toward science in the experimental group became more positive (+1.34) after the four-month period. An analysis of positive

  5. Does alignment of constructivist teaching, curriculum, and assessment strategies promote meaningful learning?

    Science.gov (United States)

    Jimarez, Teresa

    Despite our national efforts to attract more students to the science, technology, engineering, and mathematics (STEM) fields, the number of students continues to be small. Empirical studies have suggested that in order to actively engage students in the science learning processes, lessons need to be designed which consider student prior experiences and provide a sound curriculum, within an environment promoting social interaction---that is, allowing for sharing and negotiation of those ideas which promote reflective thinking. These premises require an embedded assessment system that continuously provides feedback to both student and teacher. This technique allows adaptation and modification of lessons to better facilitate conceptual understanding. This study focused on the use of constructivist strategies that, when aligned, promoted conceptual understanding while facilitating development of science process skills. Skill development leads to meaningful learning, known to promote a change of attitude toward science. A mixed research design embedded in a case study approach was used to understand the complexity of the variables examined in this study. Both quantitative and qualitative methods of data collection were used to strengthen the validity and interpretation of the findings. Students from one of three ninth-grade physical science classes were selected for this study. The students numbered 29, 13 boys and 16 girls; the majority of these students were of Hispanic background. The analysis of data suggested that the use of constructivist strategies promotes conceptual understanding of science concepts and development of science process skills and a change of attitude towards science. This study concluded that selecting teaching and multiple assessment strategies is vital to engage students in science careers. Due to the limited nature of this case study, the researcher recommends a replication or followup with a different teacher and school, including a control

    The European Union (EU), striving to create economic dominance on the global market, has prepared a comprehensive development programme, which initially was the Lisbon Strategy and then the Strategy Europe 2020. The attainment of the strategic goals included in the prospective development programmes shall transform the EU into the most competitive economy in the world based on knowledge. This paper presents a statistical evaluation of progress being made by EU member states in meeting Europe 2020. For the basis of the assessment, the authors proposed a general synthetic measure in dynamic terms, which allows to objectively compare EU member states by 10 major statistical indicators. The results indicate that most of EU countries show average progress in realisation of Europe's development programme which may suggest that the goals may not be achieved in the prescribed time. It is particularly important to monitor the implementation of Europe 2020 to arrive at the right decisions which will guarantee the accomplishment of the EU's development strategy.

    2005-01-01

    This paper aims at presenting a multiple objective model to evaluate the attractiveness of the use of demand resources (through load management control actions) by different stakeholders and in diverse structure scenarios in electricity systems. For the sake of model flexibility, the multiple (and conflicting) objective functions of technical, economical and quality of service nature are able to capture distinct market scenarios and operating entities that may be interested in promoting load management activities. The computation of compromise solutions is made by resorting to evolutionary algorithms, which are well suited to tackle multiobjective problems of combinatorial nature herein involving the identification and selection of control actions to be applied to groups of loads.

    An approach to sustainable municipal solid waste (MSW) management is presented, with the aim of supporting the decision on the optimal flows of solid waste sent to landfill, recycling and different types of treatment plants, whose sizes are also decision variables. This problem is modeled with a non-linear, multi-objective formulation. Specifically, four objectives to be minimized have been taken into account, which are related to economic costs, unrecycled waste, sanitary landfill disposal and environmental impact (incinerator emissions). An interactive reference point procedure has been developed to support decision making; these methods are considered appropriate for multi-objective decision problems in environmental applications. In addition, interactive methods are generally preferred by decision makers as they can be directly involved in the various steps of the decision process. Some results deriving from the application of the proposed procedure are presented. The application of the procedure is exemplified by considering the interaction with two different decision makers who are assumed to be in charge of planning the MSW system in the municipality of Genova (Italy).

    The task of breaking bad news (BBN) may be improved by incorporating simulation with art-based teaching methods. The aim of the present study was to assess the effect of an integrating simulation with art-based teaching strategies, on fellows' performance regarding BBN, in Iran. The study was carried out using quasi-experimental methods, interrupted time series. The participants were selected from medical oncology fellows at two teaching hospitals of Tehran University of Medical Sciences (TUMS), Iran. Participants were trained through workshop, followed by engaging participants with different types of art-based teaching methods. In order to assess the effectiveness of the integrating model, fellows' performance was rated by two independent raters (standardized patients (SPs) and faculty members) using the BBN assessment checklist. This assessment tool measured seven different domains of BBN skill. Segmented regression was used to analyze the results of study. Performance of all oncology fellows (n = 19) was assessed for 228 time points during the study, by rating three time points before and three time points after the intervention by two raters. Based on SP ratings, fellows' performance scores in post-training showed significant level changes in three domains of BBN checklist (B = 1.126, F = 3.221, G = 2.241; p art-based teaching strategies may help oncology fellows to improve their communication skills in different facets of BBN performance.

    Lacum, Edwin B. Van; Goedhart, Martin J.

    2014-01-01

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

    2009-01-01

    This paper explores the relationship between the diversification of sources of imported oil and energy security of oil-importing countries. It examines the importance of diversification policy for oil importers, explains why oil importers implement oil diversification policy, and contextualizes the oil import diversification strategy in the overall energy security policy of oil importers. The paper analyzes the factors and the contexts that affect the level of importance assigned to oil import diversification policy in oil-importing countries, and the limitations that may affect the successful implication of oil import diversification policy. The examples are drawn from the world's top three oil importers, the United States, Japan, and China. The policymakers in these and other oil-importing countries place much importance on energy security. The diversification of oil import sources is used as one of the strategies to enhance energy security in oil-importing countries. This paper is important for policymakers in oil-importing countries as it provides them with a qualitative conceptual framework with which to evaluate the need to diversify their countries' sources of imported oil, and with which to identify the likely limitations to the successful implementation of oil import diversification policy.

    A new curriculum for an introductory geology course, Geology and Everyday Thinking (GET), incorporates the key research findings of How People Learn (NAS, 1999), and is based on the pedagogical approach of Physics and Everyday Thinking (PET; http://petproject.sdsu.edu/). These key findings have profound implications for developing teaching strategies that promote student learning. They suggest that for learning to occur: 1) students' preconceptions must be engaged, 2) students must be able to build their own conceptual framework, and 3) students must be given an opportunity to reflect on their learning (metacognition). Our curriculum has been carefully constructed into cycles that apply these key findings while exploring a key geologic concept. Each cycle engages students' 'Initial Ideas' about these concepts (and continuously revisits those Initial Ideas), sequentially builds upon concepts in a logical framework, and requires reflective writing. The curriculum employs questioning, small group work, and small and large class discussions. Students construct concepts by doing inquiry lab activities, but embedded group discussions that promote discourse and questioning among students is a crucial tool in the sense-making and solidification of those concepts. The questioning and discourse occur throughout each module so that students' preconceptions about a particular concept are brought out early on, and are revisited and challenged again as students construct their new understanding. Whiteboarding, or the process of sharing small-group ideas to a larger group, is the primary method of generating discussion. The instructor's role as facilitator and questioner is the cornerstone in this process. The primary audience for this course is future elementary teachers, who are required take a year-long science sequence. The year-long sequence includes physics (PET), geology (GET), and a correlative new curriculum in biology (BET). Class size is limited to 24 students, and the

    Full Text Available Abstract Background The General Medical Council states that teaching doctors and students is important for the care of patients. Our aim was to deliver a structured teaching program to final year medical students, evaluate the efficacy of teaching given by junior doctors and review the pertinent literature. Methods We developed a revision package for final year medical students sitting the Objective Structured Clinical Examination (OSCE. The package was created and delivered exclusively by recent medical graduates and consisted of lectures and small group seminars covering the core areas of medicine and surgery, with a focus on specific OSCE station examples. Students were asked to complete a feedback questionnaire during and immediately after the program. Results One hundred and eighteen completed feedback questionnaires were analysed. All participants stated that the content covered was relevant to their revision. 73.2% stated that junior doctors delivered teaching that is comparable to that of consultant - led teaching. 97.9% stated the revision course had a positive influence on their learning. Conclusions Our study showed that recent medical graduates are able to create and deliver a structured, formal revision program and provide a unique perspective to exam preparation that was very well received by our student cohort. The role of junior doctors teaching medical students in a formal structured environment is very valuable and should be encouraged.

    2012-04-01

    In spite of the critical role of the Arctic Ocean in climate evolution, our understanding of the short- and long-term paleoceanographic and paleoclimatic history through late Mesozoic-Cenozoic times, as well as its plate-tectonic evolution, remains behind that from the other world's oceans. This lack of knowledge is mainly caused by the major technological/logistic problems in reaching this permanently ice-covered region with normal research vessels and in retrieving long and undisturbed sediment cores. With the Arctic Coring Expedition - ACEX (or IODP Expedition 302), the first Mission Specific Platform (MSP) expedition within IODP, a new era in Arctic research began (Backman, Moran, Mayer, McInroy et al., 2006). ACEX proved that, with an intensive ice-management strategy, successful scientific drilling in the permanently ice-covered central Arctic Ocean is possible. ACEX is certainly a milestone in Arctic Ocean research, but - of course - further drilling activities are needed in this poorly studied ocean. Furthermore, despite the success of ACEX fundamental questions related to the long- and short-term climate history of the Arctic Ocean during Mesozoic-Cenozoic times remain unanswered. This is partly due to poor core recovery during ACEX and, especially, because of a major mid-Cenozoic hiatus in this single record. Since ACEX, a series of workshops were held to develop a scientific drilling strategy for investigating the tectonic and paleoceanographic history of the Arctic Ocean and its role in influencing the global climate system: - "Arctic Ocean History: From Speculation to Reality" (Bremerhaven/Germany, November 2008); - "Overcoming barriers to Arctic Ocean scientific drilling: the site survey challenge" (Copenhagen/Denmark, November 2011); - Circum-Arctic shelf/upper continental slope scientific drilling workshop on "Catching Climate Change in Progress" (San Francisco/USA, December 2011); - "Coordinated Scientific Drilling in the Beaufort Sea: Addressing

    2016-07-01

    Full Text Available To help students navigate the digital environment, teachers not only need access to the right technology tools but they must also engage in pedagogically sound, high-quality professional development. For teachers, quality professional development can mean the difference between merely using technology tools and creating transformative change in the classroom. For students — especially those with learning disabilities (SWLDs — having well-prepared teachers can mean the difference between passive listening and active learning. This report discusses implementation and impact of a face-to-face professional development model designed to enhance teachers’ implementation of a web-based curriculum (the SOAR Student Toolkit for teaching online research strategies to all students (both general education students and SWLDs in the middle school classroom. Fifteen teachers and 446 students participated in this study. Data were gathered from three school-based implementations across two academic years. Results indicate that teachers found that the face-to-face professional development was of high quality (100%, the pace and format was appropriate (93%, and sufficient practice and feedback were provided (100%. All teachers said the professional development supported their professional growth in providing differentiated instruction for all students and integrating technology into their instruction. About half of the students agreed or strongly agreed that they were very happy with the use of the SOAR Student Toolkit, found it easy to use, believed it helped them learn online research strategies, and thought it was a good way to teach. Most students said they would use the SOAR Student Toolkit for future research projects at least sometimes. Students who learned the SOAR Student Toolkit from trained teachers improved scores an average of 29.2 percentage points on performance-based assessments, from 31.3% (SD = 22.1 at pretest to 60.5% (SD = 23.0 at

    Directory of Open Access Journals (Sweden)

    Lei Ma

    2016-09-01

    Full Text Available Object-based change detection (OBCD has recently been receiving increasing attention as a result of rapid improvements in the resolution of remote sensing data. However, some OBCD issues relating to the segmentation of high-resolution images remain to be explored. For example, segmentation units derived using different segmentation strategies, segmentation scales, feature space, and change detection methods have rarely been assessed. In this study, we have tested four common unsupervised change detection methods using different segmentation strategies and a series of segmentation scale parameters on two WorldView-2 images of urban areas. We have also evaluated the effect of adding extra textural and Normalized Difference Vegetation Index (NDVI information instead of using only spectral information. Our results indicated that change detection methods performed better at a medium scale than at a fine scale where close to the pixel size. Multivariate Alteration Detection (MAD always outperformed the other methods tested, at the same confidence level. The overall accuracy appeared to benefit from using a two-date segmentation strategy rather than single-date segmentation. Adding textural and NDVI information appeared to reduce detection accuracy, but the magnitude of this reduction was not consistent across the different unsupervised methods and segmentation strategies. We conclude that a two-date segmentation strategy is useful for change detection in high-resolution imagery, but that the optimization of thresholds is critical for unsupervised change detection methods. Advanced methods need be explored that can take advantage of additional textural or other parameters.

Interaction analysis reinforced that successful undergraduate-teaching assistant communication depends on the coordination of verbal and visual channels of communication, with the physical objects of the chemistry lab environment playing a pivotal role in expressing information and in mutual understanding. These results have implications for the evaluation of English proficiency and the preparation of non-native speaking teaching assistants by pointing out that teaching assistant listening comprehension skills and the use of contextual artifacts contribute to successful communication and are areas that, to date, have been underrepresented in the research literature on international teaching assistant communication.

    Thermoelectric materials provide a renewable and eco-friendly solution to mitigate energy shortages and to reduce environmental pollution via direct heat-to-electricity conversion. Discovery of the novel thermoelectric materials and optimization of the state-of-the-art material systems lie at the core of the thermoelectric society, the basic concept behind these being comprehension and manipulation of the physical principles and transport properties regarding thermoelectric materials. In this mini-review, certain examples for designing high-performance bulk thermoelectric materials are presented from the perspectives of both real objects and local fields. The highlights of this topic involve the Rashba effect, Peierls distortion, local magnetic field, and local stress field, which cover several aspects in the field of thermoelectric research. We conclude with an overview of future developments in thermoelectricity.

    2013-01-15

    In recent years, Europe has promoted a series of waste regulations to achieve greater protection of the environment. This objective can be obtained by adopting an integrated management system for the reduction of waste production and developing systems for waste sorting, energy recovery and waste recycling. Such interventions that find their justification in an environmental perspective must be also sustainable from an economic perspective. An analysis of the Italian situation highlights a dependency on landfills; this phenomenon must be reduced to identify actions aimed at safeguarding and protecting the environment. The aim of this paper is to analyse the economic and environmental benefits from diverting waste from landfills towards energy recovery in twenty Italian regions. Copyright © 2012 Elsevier B.V.

    Yerramasu, Ajay; Venuraju, Shreenidhi; Atwal, Satvir; Goodman, Dennis; Lipkin, David; Lahiri, Avijit

    2012-01-01

    Background: CT coronary angiography (CTCA) is an evolving modality for the diagnosis of coronary artery disease. Radiation burden associated with CTCA has been a major concern in the wider application of this technique. It is important to reduce the radiation dose without compromising the image quality. Objectives: To estimate the radiation dose of CTCA in clinical practice and evaluate the effect of dose-saving algorithms on radiation dose and image quality. Methods: Effective radiation dose was measured from the dose-length product in 616 consecutive patients (mean age 58 ± 12 years; 70% males) who underwent clinically indicated CTCA at our institution over 1 year. Image quality was assessed subjectively using a 4-point scale and objectively by measuring the signal- and contrast-to-noise ratios in the coronary arteries. Multivariate linear regression analysis was used to identify factors independently associated with radiation dose. Results: Mean effective radiation dose of CTCA was 6.6 ± 3.3 mSv. Radiation dose was significantly reduced by dose saving algorithms such as 100 kV imaging (−47%; 95% CI, −44% to −50%), prospective gating (−35%; 95% CI, −29% to −40%) and ECG controlled tube current modulation (−23%; 95% CI, −9% to −34%). None of the dose saving algorithms were associated with a significant reduction in mean image quality or the frequency of diagnostic scans (P = non-significant for all comparisons). Conclusion: Careful application of radiation-dose saving algorithms in appropriately selected patients can reduce the radiation burden of CTCA significantly, without compromising the image quality.

  10. Compensatory motor control after stroke: an alternative joint strategy for object-dependent shaping of hand posture.

    Raghavan, Preeti; Santello, Marco; Gordon, Andrew M; Krakauer, John W

    2010-06-01

    Efficient grasping requires planned and accurate coordination of finger movements to approximate the shape of an object before contact. In healthy subjects, hand shaping is known to occur early in reach under predominantly feedforward control. In patients with hemiparesis after stroke, execution of coordinated digit motion during grasping is impaired as a result of damage to the corticospinal tract. The question addressed here is whether patients with hemiparesis are able to compensate for their execution deficit with a qualitatively different grasp strategy that still allows them to differentiate hand posture to object shape. Subjects grasped a rectangular, concave, and convex object while wearing an instrumented glove. Reach-to-grasp was divided into three phases based on wrist kinematics: reach acceleration (reach onset to peak horizontal wrist velocity), reach deceleration (peak horizontal wrist velocity to reach offset), and grasp (reach offset to lift-off). Patients showed reduced finger abduction, proximal interphalangeal joint (PIP) flexion, and metacarpophalangeal joint (MCP) extension at object grasp across all three shapes compared with controls; however, they were able to partially differentiate hand posture for the convex and concave shapes using a compensatory strategy that involved increased MCP flexion rather than the PIP flexion seen in controls. Interestingly, shape-specific hand postures did not unfold initially during reach acceleration as seen in controls, but instead evolved later during reach deceleration, which suggests increased reliance on sensory feedback. These results indicate that kinematic analysis can identify and quantify within-limb compensatory motor control strategies after stroke. From a clinical perspective, quantitative study of compensation is important to better understand the process of recovery from brain injury. From a motor control perspective, compensation can be considered a model for how joint redundancy is exploited

    Studies indicate that many teachers have negative beliefs about science, which translates into low teacher efficacy, resulting in avoidance of science teaching or in ineffective science teaching behaviors. Highly efficacious teachers have been found to be more likely to use inquiry and student-centered teaching strategies, while teachers with a low sense of science-teaching efficacy are more likely to use teacher-directed strategies, such as didactic lectures and reading from the textbook (Czemiak, 1990). The purpose of this study was to investigate preservice science teachers' science-teaching self-efficacy changes and their correlation to teaching environment factors during the student teaching semester. Moreover, it explains how teaching environment factors and preservice teachers' science-teaching self-efficacy beliefs may relate to their use of teaching strategies in the science classroom during their student teacher training at teachers' colleges in Saudi Arabia. The population of this study is consisted of 184 middle and elementary preservice science teachers who were doing their student teaching at nine teachers' colleges (i.e., teachers' colleges of Riyadh, Dammam, Alrras, Almadinah, Alihsa, Jeddah, Makah, Altaief, and Abha) in Saudi Arabia during the spring semester of 2005. Three instruments were used to collect data for this study: (1) to measure science teaching self-efficacy, the researcher adapted the Science Teaching Efficacy Belief Instrument form B designed specifically for preservice teachers (STEBI-B); (2) to measure the school environment, the researcher adapted the Organizational Health Inventory (OHI), developed by Hoy, Tarter & Kottkamp (1991); and (3) to measure the type and frequency of instructional strategies that preservice science teachers use in the classroom, the researcher adapted the teaching practice subscale from The Local Systemic Change through Teacher Enhancement Science K-8 Teacher Questionnaire (Horizon Research, Inc., 2000

    Background. Pediatric medical information provision literature focuses on hospitalization and surgical procedures, but children would also benefit from an educational program regarding more commonly experienced medical procedures (e.g., needles, general check-up). Objective. To determine whether an evidence-based educational program reduced children's ratings of fear of and expected pain from medical stimuli and increased their knowledge of procedural coping strategies. Methods. An educational, interactive, developmentally appropriate Teddy Bear Clinic Tour was developed and delivered at a veterinary clinic. During this tour, 71 5-10-year-old children (Mage = 6.62 years, SD = 1.19) were taught about medical equipment, procedures, and coping strategies through modelling and rehearsal. In a single-group, pretest posttest design, participants reported their fear of and expected pain from medical and nonmedical stimuli. Children were also asked to report strategies they would use to cope with procedural fear. Results. Children's ratings for expected pain during a needle procedure were reduced following the intervention. No significant change occurred in children's fear of needles. Children reported more intervention-taught coping strategies at Time 2. Conclusions. The results of this study suggest that an evidence-based, interactive educational program can reduce young children's expectations of needle pain and may help teach them procedural coping strategies.

    Emission of light by a single electron moving on a curved trajectory (synchrotron radiation) is one of the most well-known fundamental radiation phenomena. However experimental situations are more complex as they involve many electrons, each being exposed to the radiation of its neighbors. This interaction has dramatic consequences, one of the most spectacular being the spontaneous formation of spatial structures inside electrons bunches. This fundamental effect is actively studied as it represents one of the most fundamental limitations in electron accelerators, and at the same time a source of intense terahertz radiation (Coherent Synchrotron Radiation, or CSR). Here we demonstrate the possibility to directly observe the electron bunch microstructures with subpicosecond resolution, in a storage ring accelerator. The principle is to monitor the terahertz pulses emitted by the structures, using a strategy from photonics, time-stretch, consisting in slowing-down the phenomena before recording. This opens the way to unpreceeded possibilities for analyzing and mastering new generation high power coherent synchrotron sources.

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

    To evaluate the effectiveness of a strategy for teaching neonatal resuscitation on the cognitive knowledge of health professionals who attend deliveries in Ghana, West Africa. Train-the-trainer model was used to train health professionals at 2-3 day workshops from 2003 to 2007. Obstetric Anticipatory Care and Basic Neonatal Care modules were taught as part of Neonatal Resuscitation Training package. American Neonatal Resuscitation Program was adapted to the clinical role of participants and local resources. Cognitive knowledge was evaluated by written pre- and post-training tests. The median pre-training and post-training scores were 38% and 71% for midwives, 43% and 81% for nurses, 52% and 90% for nurse anaesthetists, and 62% and 98% for physicians. All groups of the 271 professionals (18 nurse anaesthetists, 55 nurses, 68 physicians, and 130 midwives) who completed the course showed significant improvement (pfacilities were less likely to achieve passing post-test scores than midwives at secondary and tertiary facilities [35/53 vs. 24/26 vs. 45/51 (p=0.004)] respectively. Evidence-based neonatal resuscitation training adapted to local resources significantly improved cognitive knowledge of all groups of health professionals. Further modification of training for midwives working at primary level health facilities and incorporation of neonatal resuscitation in continuing education and professional training programs are recommended.

    The traditional "teacher-centered" instruction model is still currently pervasive in nursing education. However, this model does not stimulate the critical thinking or foster the self-learning competence of students. In recent years, the rapid development of information technology and the changes in educational philosophy have encouraged the development of the "flipped classroom" concept. This concept completely subverts the traditional instruction model by allowing students to access and use related learning activities prior to class on their smartphones or tablet computers. Implementation of this concept has been demonstrated to facilitate greater classroom interaction between teachers and students, to stimulate student thinking, to guide problem solving, and to encourage cooperative learning and knowledge utilization in order to achieve the ideal of student-centered education. This student-centered model of instruction coincides with the philosophy of nursing education and may foster the professional competence of nursing students. The flipped classroom is already an international trend, and certain domestic education sectors have adopted and applied this concept as well. However, this concept has only just begun to make its mark on nursing education. This article describes the concept of the flipped classroom, the implementation myth, the current experience with implementing this concept in international healthcare education, and the challenging issues. We hope to provide a reference for future nursing education administrators who are responsible to implement flipped classroom teaching strategies in Taiwan.

    The Art Rounds program uses visual thinking strategies (VTS) to teach visual observation skills to medical and nursing students at the University of Texas Health Science Center San Antonio. This study's goal was to evaluate whether students' exposure to VTS would improve their physical observation skills, increase tolerance for ambiguity, and increase interest in learning communication skills. In January 2010, 32 students attended three, 90-minute sessions at which they observed and commented on three pieces of art in small groups led by museum educators. Pre and posttest evaluations included Geller and colleagues' version of Budner's Tolerance of Ambiguity Scale, the Communication Skills Attitudes Scale, and free responses to art and patient images. Statistical analyses compared pre and post time looking at images, number of words used to describe images, and number of observations made according to gender and discipline. Students significantly increased the amount of time they spent looking at art and patient images (P = .007), the number of words they used to describe art (P = .002) and patient images (P = .019), and the number of observations made of art (P = .000) and patient images (P = .001). Females increased the time spent observing significantly more than did males (P = .011). Students significantly increased their tolerance for ambiguity (P = .033) and positive views toward health care professional communication skills (P = .001). The authors speculate that these improved skills may help in patient care and interprofessional team interactions.

    Pathology is an essential course for many students in the biomedical sciences and allied health professions. These students learn the language of pathology and medicine, develop an appreciation for mechanisms of disease, and understand the close relationship between basic research and clinical medicine. We have developed 3 pathology courses to meet the needs of our undergraduates, graduate students, and allied health professionals. Through experience, we have settled on an approach to teaching pathology that takes into account the diverse educational backgrounds of these students. Educational resources such as assigned reading, online homework, lectures, and review sessions are carefully balanced to adjust course difficulty. Common features of our pathology curricula include a web-based computer laboratory and review sessions on the basis of selected pathology images and open-ended study questions. Lectures, computer-guided homework, and review sessions provide the core educational content for undergraduates. Graduate students, using the same computer program and review material, rely more heavily on assigned reading for core educational content. Our experience adapting a pathology curriculum to the needs of divergent groups of students suggests a general strategy for monitoring course difficulty. We hypothesize that course difficulty is proportional to the information density of specific learning resources (eg, lecture or textbook) multiplied by the weight of those learning resources placed on examinations. This formula allows educators to match the difficulty of a course with the educational needs of students, and provides a useful tool for longitudinal studies of curriculum reform.

Los mapas perceptuales son herramientas para el análisis del posicionamiento de marca, y se enseñan en cursos de pregrado y postgrado. Sin embargo, es muy usual utilizar un marco puramente descriptivo y teórico, sin explicar los mecanismos para construirlos. Se presentan métodos basados en regresión multilineal y en análisis factorial como herramientas de modelado, para explicar en clase y proporcionar una mejor comprensión de esta materia. ABSTRACT: This paper comprises the design of a strategy to teach perceptual mapping in a Brand Management course, adding a modeling technique in order to elaborate such maps. Perceptual maps are tools used to analyze the positioning of a brand, and are taught in undergraduate and graduate courses. However, very frequently a purely descriptive and theoretical framework is used, disregarding the mechanisms to construct them. Methods based on multiple linear regression and factorial analysis are presented as modeling tools to explain and foster a better understanding of this subject in class.

    Full Text Available This study was an attempt to systematically investigate the comparative impact of teaching Metacognitive Strategies (MS and Collaborative Strategic Reading (CSR on English as a Foreign Language (EFL learners' Reading Comprehension (RC. The participants were 58 homogenized intermediate level female EFL learners, within the age range of 18-30 (Mage = 24; they were non-randomly selected and were randomly assigned into two experimental groups of 29. One experimental group received MS training based on Anderson's (2002 model, and the other experimental group received training in CSR based on Klingner and Vaughn’s (1998 model. Inspecting the initially-homogenized participants’ post-treatment performance, through using a piloted PET reading test and running an independent-samples t-test, revealed that the MS group performed significantly better than the CSR group in terms of RC. The study concludes with a discussion on the obtained results, followed by presenting some implications for EFL teachers, EFL learners, and EFL material developers.
