ABSTRACT

Since 2002, library faculty at the Indiana University School of Medicine have taught third-year medical students how to retrieve the best evidence from MEDLINE to address their clinical questions. In preparation for their Neurology, Medicine, and Psychiatry clerkships, students attended a review of evidence-based medicine principles and techniques for searching the literature. The session was team-taught by two faculty members, one from the Internal Medicine department and the other from the Library. The librarian reviewed important MEDLINE principles for constructing a good subject search and applying appropriate evidence-based filters. During the clerkships, students were asked to generate clinical questions arising from their patient encounters, searched MEDLINE for the best evidence, critiqued the results, and then applied them back to their patients' care. Library faculty provided individualized feedback on the student searches. A follow-up session two months later reinforced MEDLINE principles, used student searches as examples, and extended the discussion to other evidence-based, point-of-care resources. To add to the interactivity of the follow-up sessions, librarians used an audience response system to measure students' understanding of literature retrieval techniques and to gauge student preferences for information seeking on clinical topics. Overall, the sessions have been well-received by the students.  相似文献   

Needed: new models for linking the two cultures     

Vincent N. Lunetta  John Dekkers 《International Journal of Science Education》2013,35(2):149-160

In recent years problems facing humankind have become more complex and challenging and have increasingly involved science and technology. While the public, generally, has been inadequately informed about such scientific and technical issues, public understanding of issues at the interface of science, society, and technology are an essential part of the resolution of societal problems. This paper outlines specific ways to promote understanding enabling individuals to participate more responsibly in enlightened democratic decision‐making responsive to societal needs. A systematic scheme is outlined with examples from two science education centres at tertiary institutions through activities including teaching, outreach, curriculum development, and research.  相似文献   

Supporting Educators to Implement Mand Training for a Student with Multiple Disabilities     

Virginia L. Walker  Stephanie N. DeSpain  James R. Thompson 《Exceptionality》2013,21(4):262-277

ABSTRACT

The purposes of the study were to assess the effects of an online learning module on the implementation of mand training by a classroom team and determine whether training improved manding for a student with multiple disabilities. The classroom team utilized the Support Needs Assessment and Planning (SNAP) process to identify supports and guide implementation of the mand training procedures. The results indicate that both the special education teacher and paraprofessional were able to implement the mand training strategy with fidelity after completing the online module and student manding increased. The classroom team reported that both the online learning module and SNAP process were valuable for planning and implementing research-based supports. Limitations, implications for practice, and future research considerations are addressed.  相似文献   

Falling in love and staying in love with science: ongoing informal science experiences support fascination for all children     

Rachel N. Bonnette  Kevin Crowley  Christian D. Schunn 《International Journal of Science Education》2013,35(12):1626-1643

ABSTRACT

Ages 10–14 mark a period in which children develop a strong sense of whether science is ‘for them,’ a time that typically coincides with the start of middle school in the United States and their first exposure to more rigorous science classes and testing. Experiences with science in and out of school can shape children's motivation to choose science careers or participate in voluntary science classes later on, for better or worse. We explore the hypothesis that children who engage in more informal educational science experiences at the start of this period are more likely than their peers to obtain and maintain interest, curiosity, and mastery goals in science (together forming a construct called fascination). We measured 983 children's fascination with science at the beginning and middle of sixth grade. We found that the children who participated in informal science during this time were more likely to maintain or have greater fascination than at the start. These findings held while also controlling for many potentially confounding covariates and are robust across subgroups by gender and race/ethnicity. Further, the effects are largest for those children whose family generally supports their learning.  相似文献   

What is the relationship between social constructivism and Piagetian constructivism? An analysis of the characteristics of the ideas within both theories     

N. Marin  A. Benarroch  E. Jimenez Gomez 《International Journal of Science Education》2013,35(3):225-238

For twenty years, social constructivism has been a paradigm in science teaching and not an easy bedfellow for piagetian constructivism, even though both have had the same thing in mind… a study of the learner. For this reason we attempt to find connections and bridges between them so that both may be enriched, to the benefit of science teaching.  相似文献   

Learning Difficulties in School Science‐‐Towards a Working Hypothesis

In an attempt to explain success and failure in problem‐solving by science students, the authors suggest that problem‐solving ability is associated with students’ ability to organize or ‘chunk’ the information provided in a problem into memorizable patterns. In line with general psychological findings, a short‐term memory capacity of 7 ± 2 chunks is accepted. If the short‐term memory is overloaded with too many pieces of information, the processing of this information (and, hence, effective problem‐solving) cannot take place unless such information can be effectively chunked. This hypothesis, which is derived from research studies, is exemplified by reference to chemical problems and its educational implications are discussed.  相似文献

Essential Criteria to Characterize Constructivist Teaching: Derived from a review of the literature and applied to five constructivist‐teaching method articles     

Sandhya N. Baviskar  R. Todd Hartle  Tiffany Whitney 《International Journal of Science Education》2013,35(4):541-550

Constructivism is an important theory of learning that is used to guide the development of new teaching methods, particularly in science education. However, because it is a theory of learning and not of teaching, constructivism is often either misused or misunderstood. Here we describe the four essential features of constructivism: eliciting prior knowledge, creating cognitive dissonance, application of new knowledge with feedback, and reflection on learning. We then use the criteria we developed to evaluate five representative published articles that claim to describe and test constructivist teaching methods. Of these five articles, we demonstrate that three do not adhere to the constructivist criteria, whereas two provide strong examples of how constructivism can be employed as a teaching method. We suggest that application of the four essential criteria will be a useful tool for all professional educators who plan to implement or evaluate constructivist teaching methods.  相似文献   

Teaching and learning about human nutrition: a constructivist approach     

Enrique Banet  Francisco Núñez 《International Journal of Science Education》2013,35(10):1169-1194

The results of a constructivism‐based teaching programme on human nutrition for students in the second year of secondary education (13‐ and 14‐year‐olds) are analysed in light of the ideas held by the students before and after implementation of the programme. The results show how most of the students who participated in this programme reorganized their ideas concerning the nutritional process and achieved a fuller understanding of how nutrition comprises a series of related and integrated processes. Other students, who followed a more conventional method based on the teacher explanation and textbooks, tended to have erroneous or incomplete ideas concerning the nutritional process.  相似文献   

Diagnosing Portuguese Students' Misconceptions about the Mineral Concept     

António Monteiro  Clévio Nóbrega  Isabel Abrantes  Celeste Gomes 《International Journal of Science Education》2013,35(17):2705-2726

Educational researchers and teachers are well aware that misconceptions—erroneous ideas that differ from the scientifically accepted ones—are very common amongst students. Daily experiences, creative and perceptive thinking and science textbooks give rise to students' misconceptions which lead them to draw erroneous conclusions that become strongly attached to their views and somehow affect subsequent learning. The main scope of this study was to understand what students consider a mineral to be and why. Therefore, the goals were (1) to identify eleventh-grade students' misconceptions about the mineral concept; (2) to understand which variables (gender, parents' education level and attitude towards science) influenced students' conceptions; and (3) to create teaching tools for the prevention of misconceptions. In order to achieve these goals, a diagnostic instrument (DI), constituted of a two-tier diagnostic test and a Science Attitude Questionnaire, was developed to be used with a sample of 89 twelfth-grade students from five schools located in central Portugal. As far as we know, this is the first DI developed for the analysis of misconceptions about the mineral concept. Data analysis allows us to conclude that students had serious difficulties in understanding the mineral concept, having easily formed misconceptions. The variables gender and parents' education level influence certain students' conceptions. This study provides a valuable basis for reflection on teaching and learning strategies, especially on this particular theme.  相似文献
