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

AbstractGraduate students and postdoctoral researchers are increasingly taking on mentoring roles in undergraduate research (UR). There is, however, a paucity of research focusing on how they conceptualize their mentoring role. In this qualitative interview study, we identified three entry points that mentors reflect on to define their role: (1) What are the goals of UR? (2) What do the students expect from me? and (3) How should I use my expert knowledge? We discuss how academic developers can use these entry points together with a set of reflective lenses to stimulate critical reflection on the mentoring role and help the mentors to define their role and help the mentors to define their role. 相似文献

In response to the authors, I demonstrate how threshold concepts offer a means to both contextualise teaching and learning of quantum physics and help transform students into the culture of physics, and as a way to identify particularly troublesome concepts within quantum physics. By drawing parallels from my own doctoral research in another area of contemporary physics—special relativity—I highlight concepts that require an ontological change, namely a shift beyond the reality of everyday Newtonian experience such as time dilation and length contraction, as being troublesome concepts that can present barriers to learning with students often asking “is it real?”. Similarly, the domain of quantum physics requires students to move beyond “common sense” perception as it brings into sharp focus the difference between what is experienced via the sense perceptions and the mental abstraction of phenomena. And it’s this issue that highlights the important role imagery and creativity have both in quantum physics and in the evolution of physics more generally, and lies in stark contrast to the apparent mathematical focus and lack of opportunity for students to explore ontological issues evident in the authors’ research. By reflecting on the authors’ observations of a focus on mathematical formalisms and problem solving at the expense of alternative approaches, I explore the dialectic between Heisenberg’s highly mathematical approach and Schrödinger’s mechanical wave view of the atom, together with its conceptual imagery, at the heart of the evolution of quantum mechanics. In turn, I highlight the significance of imagery, imagination and intuition in quantum physics, together with the importance of adopting an epistemological pluralism—multiple ways of knowing and thinking—in physics education. Again drawing parallels with the authors’ work and my own, I identify the role thought experiments have in both quantum physics education and in physics more generally. By introducing the notion of play, I advocate adopting and celebrating multiple approaches of teaching and learning, including thought experiments, play, dialogue and a more conceptual approach inclusive of multiple forms of representation, that complements the current instructional, mathematical approach so as to provide better balance to learning, teaching and the curriculum. 相似文献

Does one need to think like a scientist to learn science? To what extent can examining the cognitive activities of scientists provide insights for developing effective pedagogical practices? The cognition and instruction literature has focused on providing a model of expert knowledge structures. To answer these questions, what is needed is a model of expert reasoning practices. This analysis is a step in that direction. It focuses on a tacit dimension of the thinking practices of expert physicists, “constructive modeling”. Drawing on studies of historical cases and protocol accounts of expert reasoning in scientific problem solving, it is argued that having expertise in physics requires facility with the practice of “constructive modeling” that includes the ability to reason with models viewed generically. Issues pertaining to why and how this practice of experts might be incorporated into teaching are explored. 相似文献

This study explores the effectiveness of a cooperative learning (CL) approach, where students work together and elaborate concepts of physics. The group problem‐solving tasks were conceptual questions from physics, where the students had to discuss and provide explanations of some phenomena. The effectiveness of the learning‐in‐groups approach was validated and correlated with working group interactiveness. Two group variables were assigned: the group performance and the group activity. These variables and the subjects' participation variable were correlated with achievement. Discourse analysis revealed variation in the nature of the interactions and information exchange, and the two roles as learners and learning facilitators. In addition, the study provided evidence for some features of cooperative learning that could characterize it as a nonlinear dynamical process. Implications of the findings are discussed. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 556–576, 2006 相似文献

Many studies have previously focused on how people with different levels of expertise solve physics problems. In early work, focus was on characterising differences between experts and novices and a key finding was the central role that propositionally expressed principles and laws play in expert, but not novice, problem-solving. A more recent line of research has focused on characterising continuity between experts and novices at the level of non-propositional knowledge structures and processes such as image-schemas, imagistic simulation and analogical reasoning. This study contributes to an emerging literature addressing the coordination of both propositional and non-propositional knowledge structures and processes in the development of expertise. Specifically, in this paper, we compare problem-solving across two levels of expertise—undergraduate students of chemistry and Ph.D. students in physical chemistry—identifying differences in how conceptual metaphors (CMs) are used (or not) to coordinate propositional and non-propositional knowledge structures in the context of solving problems on entropy. It is hypothesised that the acquisition of expertise involves learning to coordinate the use of CMs to interpret propositional (linguistic and mathematical) knowledge and apply it to specific problem situations. Moreover, we suggest that with increasing expertise, the use of CMs involves a greater degree of subjective engagement with physical entities and processes. Implications for research on learning and instructional practice are discussed. 相似文献

This study explored the use of wikis in a science inquiry-based project conducted with Primary 6 students (aged 11–12). It used an online wiki-based platform called PBworks and addressed the following research questions: (1) What are students’ attitudes toward learning with wikis? (2) What are students’ interactions in online group collaboration with wikis? (3) What have students learned with wikis in a science inquiry-based project in a primary school context? Analyses of the quantitative and qualitative data showed that with respect to the first research question, the students held positive attitudes toward the platform at the end of the study. With respect to the second research question, the students actively engaged in various forms of learning-related interactions using the platform that extended to more meaningful offline interactions. With respect to the third research question, the students developed Internet search skills, collaborative problem solving competencies, and critical inquiry abilities. It is concluded that a well-planned wiki-based learning experience, framed within an inquiry project-based approach facilitated by students’ online collaborative knowledge construction, is conducive to the learning and teaching of science inquiry-based projects in primary school. 相似文献

工业社会以来所形成的班级上课制,多是按照固定脚本(教案)实施教学的,学生在教学中的角色多是预设好的。知识建构教学反对用固定脚本过多的控制学生,提倡通过学生对知识的主动认知自发生成角色。因此,需要不断探明的一个主要问题是:生成的角色会如何演化?其演变对知识建构教学的效果有什么样的影响?本研究采用基于设计的研究方法,力图在小学三年级一个班级一个学期科学课的教学实践中,持续优化知识建构教学过程,进而探究该学习社区中学生的生成性角色的类型及其演变规律。数据统计与分析主要采用时间序列分析法和多重线性回归分析法,对学生的课堂会话进行编码、统计与分析。研究结果表明:知识建构社区中会自动生成五类典型的角色,并随时间推进产生不同的演变。摸清五种生成性角色的演变规律,有助于教学实践者辨别角色类型、诊断角色问题、预测角色变化。底层规律的揭示,也将对深入挖掘知识建构社区中的角色定位提供一定的理论支持。 相似文献

Toward preparing students for change: A critical discussion of the contribution of the history of physics in physics teaching 总被引：1，自引：0，他引：1
Walter Jung 《Science & Education》1994,3(2):99-130
In this paper I place physics teaching, and the inclusion of the history of physics into teaching, within a wide context. I start from the conviction that there are considerable changes ahead in the life circumstances of people in western industrial societies. This expectation should influence our aims of education generally, and in particular the aims of physics teaching. The paper does not offer final solutions, but analyses the situation and thereby argues for a change in perspective in physics teaching. The main idea is that physics teaching has to solve the problem of balancing seemingly incompatible needs, for example, conveying a stock of stable, dependable physics knowledge to students, and on the other hand to train them to see their physics knowledge within varying contexts of change. It is argued that the history of physics can be of high value in solving this problem.This article was originally published in: F. Bevilacqua and P.J.

Based on empirical findings and theoretical considerations related to the field of expertise research, the importance of “types”
and “qualities” of knowledge in relation to problem solving in physics was investigated. The students (N =138) in this study had a level of competence that corresponds to an intensive beginner college course in physics. It was
found that conceptual declarative knowledge and problem scheme knowledge are excellent predictors of problem solving performance.
However, a detailed analysis shows that the first knowledge type is more typical for low achievers (novices) in physics problem
solving whereas the second type is predominately used by high achievers (experts). Regarding types and qualities of knowledge
and their relations to problem solving, the results of a multidimensional scaling analysis (MDS) indicate that two dimensions
of knowledge can be distinguished. On the extreme limits of the first dimension, which could be named “problem solving relevance
vs. structure of discipline”, are the types of knowledge and the qualities of knowledge, respectively. The second dimension
of knowledge could be named “single knowledge elements vs. organised knowledge units”. There are types of knowledge as well
as qualities of knowledge distributed along this dimension. Consequences of these results for improving physics education
are discussed. 相似文献

This study investigated the role of broad cognitive processes in the development of mathematics skills among children and adolescents. Four hundred and forty-seven students (age mean [M] = 10.23 years, 73% boys and 27% girls) from an elementary school district in the US southwest participated. Structural equation modelling tests indicated that calculation complexity was predicted by long-term retrieval and working memory; calculation fluency was predicted by perceptual processing speed, phonetic coding, and visual processing; problem solving was predicted by fluid reasoning, crystallised knowledge, working memory, and perceptual processing speed. Younger students’ problem solving skills were more strongly associated with fluid reasoning skills, relative to older students. Conversely, older students’ problem solving skills were more strongly associated with crystallised knowledge skills, relative to younger students. Findings are consistent with the theoretical suggestion that broad cognitive processes play specific roles in the development of mathematical skills among children and adolescents. Implications for educational psychologists are discussed. 相似文献

Physics is often seen as an excellent introduction to science because it allows students to learn not only the laws governing the world around them, but also, through the problems students solve, a way of thinking which is conducive to solving problems outside of physics and even outside of science. In this article, we contest this latter idea and argue that in physics classes, students do not learn widely applicable problem-solving skills because physics education almost exclusively requires students to solve well-defined problems rather than the less-defined problems which better model problem solving outside of a formal class. Using personal, constructed, and the historical accounts of Schrödinger’s development of the wave equation and Feynman’s development of path integrals, we argue that what is missing in problem-solving education is practice in identifying gaps in knowledge and in framing these knowledge gaps as questions of the kind answerable using techniques students have learned. We discuss why these elements are typically not taught as part of the problem-solving curriculum and end with suggestions on how to incorporate these missing elements into physics classes. 相似文献

ABSTRACTWe need to know what it means to be an expert in working life today. Universities are often accused of neglecting the basic idea that higher education should be relevant to working life, and research on the subject of expertise in today’s workplace is lacking. Thirteen experts from different fields were interviewed and the obtained data were analysed using grounded theory as an analytical approach. The research questions were: (1) How do experts define expertise? (2) What kind of problems persist in their work? and (3) How are ‘routine’ and ‘adaptive’ expertise performed? The results revealed that expertise is more a social and collaborative phenomenon than an individual property. Experts develop new solutions and seek constant learning in their work. They excel at spontaneous problem solving. These findings suggest that, to prepare students to become experts, deliberate learning and practice should be provided within a framework of collaborative problem solving. 相似文献

Many researchers have stressed the importance of qualitative understanding of physical phenomena, particularly in the context of exploratory learning environments. Qualitative understanding proves to be a major part of the expert's ability to solve complex problems in physics. Some researchers think that this kind of reasoning, far from being specific to experts' knowledge, also characterizes intuitive understanding and plays a part in the transition from intuitive knowledge to more expert knowledge. It is therefore important to help students develop their qualitative reasoning and extend their existing useful conceptions. This paper presents a task analysis of a computer microworld of force and motion problems that allows students to gain a qualitative understanding of some aspects of vector algebra. The aim of the task analysis being to develop a qualitative curriculum for exploratory learning, we tried to represent the knowledge to be acquired in such a way as to promote the progressive conceptual understanding of some basic aspects of Newton's laws of motion, taking into account students' intuitive knowledge about physics. The task analysis was undertaken prior to the experimental study in order to provide guidance for students in their exploration of the microworld. The experimental work allows us to validate and extend the a priori analysis. 相似文献

The present study examined the role of conflict topics and individual differences in epistemic perspectives (absolutism, multiplism, and evaluativism) in students' explanations of expert conflicts. University students (N = 184) completed an epistemic thinking assessment and a conflict explanation assessment regarding two controversies in biology and history. Additionally, thirty students were interviewed and provided detailed conflict explanations that were used to interpret and extend the quantitative results. In the biology problem, conflicts were predominantly attributed to topic complexity and to research methods. In the history problem, conflicts were also predominantly attributed to topic complexity, but also to researchers' personal backgrounds and motivations. Epistemic perspectives were related to specific conflict explanations, suggesting that these perspectives have a role beyond topic differences. Thus, both conflict topics and epistemic perspectives shape lay explanations of experts' conflicts. The findings highlight differences in students’ interpretations of the roles experts play in knowledge construction. 相似文献

Although the development of reasoning is recognized as an important goal of science instruction, its nature remains somewhat of a mystery. This article discusses two key questions: Does formal thought constitute a structured whole? And what role does propositional logic play in advanced reasoning? Aspects of a model of advanced reasoning are presented in which hypothesis generation and testing are viewed as central processes in intellectual development. It is argued that a number of important advanced reasoning schemata are linked by these processes and should be made a part of science instruction designed to improve students' reasoning abilities. Concerning students' development and use of formal reasoning, Linn (1982) calls for research into practical issues such as the roles of task-specific knowledge and individual differences in performance, roles not emphasized by Piaget in his theory and research. From a science teacher's point of view, this is good advice. Accordingly, this article will expand upon some of the issues raised by Linn in a discussion of the nature of advanced reasoning which attempts to reconcile the apparent contradiction between students' differential use of advanced reasoning schemata in varying contexts with the notion of a general stage of formal thought. Two key questions will be discussed: Does formal thought constitute a structured whole? And what role does propositional logic play in advanced reasoning? The underlying assumption of the present discussion is that, among other things, science instruction should concern itself with the improvement of students' reasoning abilities (cf. Arons, 1976; Arons & Karplus, 1976; Bady, 1979; Bauman, 1976; Educational Policies Commission, 1966; Herron, 1978; Karplus, 1979; Kohlberg & Mayer, 1972; Moshman & Thompson, 1981; Lawson, 1979; Levine & linn, 1977; Pallrand, 1977; Renner & Lawson, 1973; Sayre & Ball, 1975; Schneider & Renner, 1980; Wollman, 1978). The questions are of interest because to date they lack clear answers, yet clear answers are necessary if we hope to design effective instruction in reasoning. 相似文献

University Students' Strategies for Constructing Hypothesis when Tackling Paper-and-Pencil Tasks in Physics 总被引：1，自引：0，他引：1

The study we present tries to explore how first year engineering students formulate hypotheses in order to construct their own problem solving structure when confronted with problems in physics. Under the constructivistic perspective of the teaching–learning process, the formulation of hypotheses plays a key role in contrasting the coherence of the students' ideas with the theoretical frame. The main research instrument used to identify students' reasoning is the written report by the student on how they have attempted four problem solving tasks in which they have been asked explicitly to formulate hypotheses. The protocols used in the assessment of the solutions consisted of a semi-quantitative study based on grids designed for the analysis of written answers. In this paper we have included two of the tasks used and the corresponding scheme for the categorisation of the answers. Details of the other two tasks are also outlined. According to our findings we would say that the majority of students judge a hypothesis to be plausible if it is congruent with their previous knowledge without rigorously checking it against the theoretical framework explained in class. 相似文献

A growing body of research has examined the experiential grounding of scientific thought and the role of experiential intuitive knowledge in science learning. Meanwhile, research in cognitive linguistics has identified many conceptual metaphors (CMs), metaphorical mappings between abstract concepts and experiential source domains, implicit in everyday and scientific language. However, the contributions of CMs to scientific understanding and reasoning are still not clear. This study explores the roles that CMs play in scientific problem-solving through a detailed analysis of two physical chemistry PhD students solving problems on entropy. We report evidence in support of three claims: a range of CMs are used in problem-solving enabling flexible, experiential construals of abstract scientific concepts; CMs are coordinated with one another and other resources supporting the alignment of qualitative and quantitative reasoning; use of CMs grounds abstract reasoning in a “narrative” discourse incorporating conceptions of paths, agents, and movement. We conclude that CMs should be added to the set of intuitive resources others have suggested contribute to expertise in science. This proposal is consistent with two assumptions: that cognition is embodied and that internal cognitive structures and processes interact with semiotic systems. The implications of the findings for learning and instruction are discussed. 相似文献
