Recently, the importance of an everyday context in physics learning, teaching, and problem‐solving has been emphasized. However, do students or physics educators really want to learn or teach physics problem‐solving in an everyday context? Are there not any obstructive factors to be considered in solving the everyday context physics problems? To obtain the answer to these questions, 93 high school students, 36 physics teachers, and nine university physics educators participated in this study. Using two types of physics problems—everyday contextual problems (E‐problems) and decontextualized problems (D‐problems)—it was found that even though there was no difference in the actual performance between E‐problems and D‐problems, subjects predicted that E‐problems were more difficult to solve. Subjects preferred E‐problems on a school physics test because they thought E‐problems were better problems. Based on the observations of students' problem‐solving processes and interviews with them, six factors were identified that could impede the successful solution of E‐problems. We also found that many physics teachers agreed that students should be able to cope with those factors; however, teachers' perceptions regarding the need for teaching those factors were low. Therefore, we suggested teacher reform through in‐service training courses to enhance skills for teaching problem‐solving in an everyday context. 相似文献

The research issue in this study is how to structure collaborative learning so that it improves solving physics problems more than individual learning. Structured collaborative learning has been compared with individual learning environments with Schoenfeld’s problem‐solving episodes. Students took a pre‐test and a post‐test and had the opportunity to solve six physics problems. Ninety‐nine students from a secondary school in Shanghai participated in the study. Students who learnt to solve problems in collaboration and students who learnt to solve problems individually with hints improved their problem‐solving skills compared with those who learnt to solve the problems individually without hints. However, it was hard to discern an extra effect for students working collaboratively with hints—although we observed these students working in a more structured way than those in the other groups. We discuss ways to further investigate effective collaborative processes for solving physics problems. 相似文献

Secondary 5 students from four schools in Hong Kong were required to classify 18 paper and pencil physics problems in terms
of whether the problems contain necessary and sufficient, missing or irrelevant information for their solution. Students'
ability to denote missing information correlated rather highly with the solution rates of the problems. In another test, students
were asked to classify whether the problems in each of six pairs were similar to or different from each other according to
students' self-determined criteria. Students who used a deep structure (i.e. used the underlying physics principles) to classify
the problems have significantly higher scores in detecting missing and irrelevant information and in the solution rates than
those who used surface structure or features for classification. It is argued that a student who is able to identify what
information is sufficient, missing or irrelevant for solving a problem understands the problem structure and so is better
able to solve it. Such a student is likely to adopt a deep structure in categorizing physics problems. This latter result
corroborates with the findings of the expert-novice research paradigm.

师范生实习支教,置换教师培训是通过组织高师院校师范生到农村中小学进行教育实习,在一定时期内顶替现职农村学校教师的岗位,被置换出的农村教师参加由高师院校组织的短期脱产培训。这是一种双赢的教学和培训模式,它有效提高了师范生的教学技能,切实解决农村教师队伍素质不高这一制约农村基础教育发展的根本问题。文章从当前教育实习和教师培训中存在的问题入手,讨论＂实习支教,置换培训＂的实践价值并对其有效实施提出了相关的建议。 相似文献

The purpose of this article is to explore how a group of four university physics students addressed mechanics problems, in terms of student direction of attention, problem solving strategies and their establishment of and ways of interacting. Adapted from positioning theory, the concepts ‘positioning’ and ‘storyline’ are used to describe and to analyse student interaction. Focused on how the students position the physics problems, themselves, and each other, the analyses produced five different storylines. The dominant storyline deals with how the students handled the problem solving, whilst two other storylines characterise alternative ways of handling the physics problems, whereas the two remaining storylines are concerned with how students positioned themselves and others—as either funny and/or knowledgeable physics students—and constitute different aspects of the physics community. Finally, the storylines are discussed in relation to the pedagogical situation, with recommendations made for teaching practice and future research. 相似文献

College students often experience difficulties in solving physics problems. These difficulties largely result from a lack of conceptual understanding of the topic. The processes of conceptual learning reflect the nature of the causal reasoning process. Two major causal reasoning methods are the covariational and the mechanism‐based approaches. This study was to investigate the effects of different causal reasoning methods on facilitating students’ conceptual understanding of physics. 125 college students from an introduction physics class were assigned into covariational group, mechanism‐based group, and control group. The results show that the mechanism‐based group significantly outperformed the other two groups in solving conceptual problems. However, no significant difference was found in all three groups performance on solving computational problems. Speculation on the inconsistent performance of the mechanism‐based group in conceptual and computational problem solving is given. Detailed analyses of the results, findings, and educational implications are discussed 相似文献
