In physics teacher education, one of the recurrent themes is the importance of fostering the formation of organised and coherent knowledge structures, but a simple shared understanding of what coherence actually means and how it can be recognised, is not easily found. This study suggests an approach in which the coherence of students’ views about the relatedness of physics concepts can be identified and evaluated. Six pre-service physics teachers presented their understanding of the relatedness of physics concepts in the form of specially designed concept maps in which experimental or modelling procedures were required as links between physics concepts. The acceptability of the links was evaluated by using four criteria for epistemic analysis introduced in this study. The weighted values describing the maps’ structural features were calculated, and finally, the cases were compared and the differences between them were discussed. The results show that the epistemic analysis of links affects remarkably to the acceptability of knowledge and thus also the coherence of such knowledge. The highest criterion set for acceptability seems to be very demanding to fulfil and even in the advanced level of studies only a fraction of students manage to reach it. The cases examined here show that the knowledge structures are partly fragmented and not as coherent as one would have expected them to be.  相似文献

As part of a project concerned with developing a better understanding of the detail of appropriate teaching of direct current (DC) electricity concepts, extensive individual interviews were conducted with a number of experienced senior high school physics teachers. These interviews explored teachers’ perceptions of difficulties in student learning and their own teaching of DC electricity, their uses of models and analogies in this teaching, and their own understandings of the concepts of DC electricity. Eight high school physics teachers from the Australian state of Victoria were interviewed: three who had a strong focus on student understanding in their classrooms and five who used more traditional approaches. We also interviewed three authors of textbooks then currently used in senior high school physics in Victoria, all of whom were also teachers of high school physics. All but one of these eleven interviewees was a very experienced teacher of DC electricity at the senior high school level. The interview data are summarized and implications for curriculum and teaching/learning of electricity are considered. There was a wide range of views among the teachers about the difficulties of both the concepts of DC electricity and the teaching of these concepts, and about the nature of physics knowledge. A number of the interviewees revealed levels of conceptual understanding that we see as of concern. Some of the teachers whose understanding causes us concern made clear early in the interview their view that the concepts of DC electricity were essentially straight forward; in all cases these interviewees had by the end of the interview reconsidered this position.  相似文献

In the Department of Physics, University of Helsinki, there are advanced physics courses designed for the needs of pre-service physics teachers. The starting point is that after introductory and intermediate physics courses, pre-service physics teachers know laws and definitions but the knowledge is quite fragmented and does not form coherent wholes. Graphical tools called didactical reconstructions were developed to help pre-service physics teachers to consolidate their physics knowledge. The idea behind the reconstructions is that “new” physics knowledge is always constructed based on previous knowledge (quantities, laws, theory). This means that every new concept is connected to previous concepts when it is formed; this is captured in the didactical reconstruction of processes. Then, when the knowledge is further constructed, the formed concept will be connected to other new concepts. This approach leads to the didactical reconstruction of structure: networks of quantities and laws, where the experiments and models construct the connections between quantities and laws. Here an overview and summary of the educational approach based on the didactical reconstruction is given for the first time. The results of the previously reported case studies show that the didactical reconstructions help students to connect the knowledge pieces into meaningful and more coherent wholes. These didactical reconstructions are now an integral part of our pre-service physics teacher education.  相似文献

We investigated how prospective teachers used physics content knowledge when analyzing the talk of elementary children during special activities in an undergraduate physics content course designed for prospective teachers. We found that prospective teachers used content knowledge to reflect on their own learning and to identify students’ science ideas and restate these ideas in scientific terms. Based on this research, we inferred that analyzing children’s ideas through videos provides a meaningful context for applying conceptual physics knowledge in physics courses. Activities that are embedded within a disciplinary curriculum, such as those studied here, may help prospective teachers learn to use disciplinary knowledge in exactly the type of activity in which their content knowledge will be most useful: listening to and interpreting children’s science ideas.  相似文献

This study describes the use of the double-slit thought experiment as a diagnostic tool for probing physics teachers’ understanding. A total of 9 pre-service teachers and 18 in-service teachers with a variety of different experience in modern physics teaching at the upper secondary level responded in a paper-and-pencil test and three of these teachers were interviewed. The results showed that the physics teachers’ thought experiments with classical particles, light, and electrons were often partial. Many teachers also suffered a lack of the basic ideas and principles of physics, which probably hindered thought experimenting. In particular, understanding the ontological nature of classical particles, light and electrons seemed to be essential in performing the double-slit experiment in an appropriate way. However, the in-service physics teachers who had teaching experience in modern physics were more prepared for the double-slit thought experiment than the pre-service teachers. The results suggest that both thought experiments and the double-slit experiment should be given more weight in physics teacher education, even if experience in modern physics teaching at upper secondary school seems to some extent to develop teachers’ abilities.  相似文献

Practical work in school science plays many essential roles that have been discussed in the literature. However, less attention has been paid to how teachers learn the different roles of practical work and to the kind of challenges they face in their learning during laboratory courses designed for teachers. In the present study we applied the principles of grounded theory to frame a set of factors that seem to set major challenges concerning both successful work in the school physics laboratory and also in the preparation of lessons that exploit practical work. The subject groups of the study were preservice and inservice physics teachers who participated in a school laboratory course. Our results derived from a detailed analysis of tutoring discussions between the instructor and the participants in the course, which revealed that the challenges in practical or laboratory work consisted of the limitations of the laboratory facilities, an insufficient knowledge of physics, problems in understanding instructional approaches, and the general organization of practical work. Based on these findings, we present our recommendations on the preparation of preservice and inservice teachers for the more effective use of practical work in school science and in school physics.  相似文献

There is a distance between the power that whole class dialogic discussions (WCDD) may offer to the science class and their use in practice. Teachers’ attitudes toward WCDD are part of the problem. The aims of this study were twofold: (a) to examine Taiwanese physics teachers’ attitudes toward WCDD by considering cultural perspectives and describe how these attitudes changed as a result of a special workshop designed for this purpose, and (b) to report on how these attitudes should be taken into account in designing such workshops in the future. Nine experienced physics teachers participated in the WCDD workshop. The workshop was based on the WCDD model developed by Eshach (2010). Inductive analyses were performed on interviews with the teachers and their students, which were composed of 36 questions and developed specially for the purpose of this study, yielded the following categories: (1) In-school reasons for opposing WCDD—reasons belonging to school ways/tradition of teaching that may cause barriers to WCDD implementation; (2) External Factors—cultural reasons relating to Taiwanese views concerning education in general, which cause barriers to WCDD implementation; and (3) Cognitive aspect—refers to what teachers know about WCDD. The paper concludes with a discussion on what should be done in order to successfully bring WCDD to the Taiwanese physics class.  相似文献

We explore the initial characterization of the pedagogical content knowledge of four, in-service, Colombian pre-university secondary education physics teachers on the concept of electric field. Two of them teach the content in English as a second language. The aim of the study was to obtain an image of the participants’ teaching of electric field and the inherent complexities that go with that. The results revealed that factors which involved their personal educational models, such as, how they interpret their school’s curriculum, the relationship they see between physics and mathematics, the most effective strategies for teaching physics, and the time they have available to develop the topic played a significant role. The teachers considered it essential to establish new strategies that would motivate the pupils by helping them visualize the electric field.  相似文献

Understanding of NOS （nature of science） appears as a prerequisite of a scientifically literate person. Promoting adequate understanding of NOS in pre-service physics teachers is, therefore, an important task of science educators. Before doing that, science educators must have information concerning their pre-service teachers＇ conceptions of NOS. This study used the MOSQ （myths of science questionnaire） to explore 17 pre-service physics teachers＇ conceptions of NOS. Commonly, these pre-service teachers expressed misunderstandings about NOS with respect to： （1） the relationship between theory and law; （2） science as cumulative; （3） subjectivity in science; （4） the scientific method; and （5） the relationship between science and technology. Science educators should consider and utilize these common misunderstandings as a basis of curricular framework for further improving pre-service physics teachers＇ understanding of NOS.  相似文献

Do physics students in pre-service training to be high-school teachers hold the accepted scientific views that will eventually allow them to plan and implement instructional strategies, which, in turn, will lead their future students to achieve a scientific concept of feree? The results of a longitudinal study dealing with this issue will be discussed in this paper. The most important findings of this study can be summarised as follows. Physics students in pre-service training for high school teachers: (1) mostly do not succeed in abandoning their Aristotelian ‘impetus’ misconception; (2) have difficulties in recognising reaction as a force; (3) are rather ambivalent when referring to the necessity of the forces to be balanced in static situations; (4) hold, to a great extent, the concept that an initial force exerted on an object keeps it going and gradually lessens--the ‘fading-away’ concept; (5) hold, to a great extent, the concept that a force (inertia), resisting a push, acts on moving objects; (6) tend to return in 4th year in college to intuitive views of force, rather than holding the accepted scientific concept.  相似文献

The world over, secondary school science is viewed mainly as a practical subject. This may be one reason why effectiveness of teaching approaches in science education has often been judged on the kinds of practical activity with which teachers and students engage. In addition to practical work, language??often written (as in science texts) or oral (as in the form of teacher and student talk)??is unavoidable in effective teaching and learning of science. Generally however, the role of (instructional) language in quality of learning of school science has remained out of focus in science education research. This has been in spite of findings in empirical research on difficulties science students encounter with words of the instructional language used in science. The findings have suggested that use of (instructional) language in science texts and classrooms can be a major influence on the level of students?? understandings and retention of science concepts. This article reports and discusses findings in an investigation of physics teachers?? approaches to use of and their beliefs about classroom instructional language. Direct classroom observations of, interviews with, as well as content analyses of the participant teachers?? verbatim classroom talk, were used as the methods of data collection. Evidence is presented of participant physics teachers?? lack of explicit awareness of the difficulty, nature, and functional value of different categories of words in the instructional language. In conclusion, the implications of this lack of explicit awareness on the general education (initial and in-service) of school physics teachers are considered.  相似文献

Analogies can play a relevant role in students’ learning. However, for the effective use of analogies, teachers should not only have a well-prepared repertoire of validated analogies, which could serve as bridges between the students’ prior knowledge and the scientific knowledge they desire them to understand, but also know how to introduce analogies in their lessons. Both aspects have been discussed in the literature in the last few decades. However, almost nothing is known about how teachers draw their own analogies for instructional purposes or, in other words, about how they reason analogically when planning and conducting teaching. This is the focus of this paper. Six secondary teachers were individually interviewed; the aim was to characterize how they perform each of the analogical reasoning subprocesses, as well as to identify their views on analogies and their use in science teaching. The results were analyzed by considering elements of both theories about analogical reasoning: the structural mapping proposed by Gentner and the analogical mechanism described by Vosniadou. A comprehensive discussion of our results makes it evident that teachers’ content knowledge on scientific topics and on analogies as well as their pedagogical content knowledge on the use of analogies influence all their analogical reasoning subprocesses. Our results also point to the need for improving teachers’ knowledge about analogies and their ability to perform analogical reasoning.  相似文献

Teaching, like other caring professions, is emotional. These emotions tend to emerge as teachers’ goals, standards, and beliefs transact with other classroom stakeholders during everyday school activities. As such, for teachers, the classroom context involves both the extreme happiness and joy from a lesson that goes as planned to the intense frustration of working with a challenging student. These academic emotions have garnered the attention of a growing number of researchers, and will be the focus of this article. More specifically, my goal is to summarize and extend our thoughts about the nature of research and our program of research related to teacher emotion.  相似文献

ABSTRACT

The authors conducted a third-party study of the student achievement effects of Struggling Schools, a user-generated approach to Comprehensive School Reform (CSR). The design was a quasiexperimental, pre–post matched sample (N = 180) with school as unit of analysis, drawing on 3 years of achievement data from standardized external assessments. Struggling Schools had a statistically significant positive effect on Grade 3 reading achievement (effect size = .48 in 2005–2006 and .60 in 2006–2007). There were enduring achievement effects 2 years after exit from the program. The outcomes indicate that CSR approaches based on capacity building, partnerships with an external agency, and accountability enhance student learning.  相似文献

Abstract

The study, with 536 second-sixth graders as subjects, attempted to investigate the relationships between teacher and “idea”-teacher discrepancies (hereafter designated as discrepancies) and six dependent variables. Results of the study were summarized as: (a) high-school achievement scorers tended to manifest low discrepancies, and vice versa; (b) boys appeared to exhibit higher discrepancies than girls did; (c) those more socially acceptable children seemed to exhibit low discrepancies, and vice versa; (d) those children who indicated higher school attitude scores had a tendency to show low discrepancies, and vice versa; (e) those children who rated themselves high on aggressiveness were inclined to show high discrepancies, and vice versa; and (f) there was no statistically significant relationship between peer-report aggressiveness and such discrepancies.  相似文献

Process-product research is conceptually truncated because it ignores that teachers are cognitive beings whose behavior is mediated by decision making. This study sought to develop inservice teachers’ interactive decision making (IDM)–their ability to “think on their feet” during instruction. An experimental group of teachers was engaged in a nine-week treatment of reflection and role-taking activities focusing on their IDM. A control group read information about IDM. Both groups then conducted lessons in the natural classroom setting and data on their IDM were collected in stimulated-recall interviews. Content analyses of the protocols produced frequency distributions on four measures of IDM. One-way analyses of variance indicated a significant difference on each measure, and effect sizes were well beyond the 80th percentile of the control group.  相似文献
