This paper addresses the parallel between the changes in students' and teachers' learning advocated by constructivist science educators. It begins with a summary of the epistemology of constructivism and uses a vignette drawn from a set of case studies to explore the impact of a constructivist science in‐service programme on an experienced and formal elementary science teacher. Judged by constructivist standards, the teacher described in the vignette makes very little progress. The irony of applying a constructivist critique to his work, however, is that it fails to treat the teachers' imperfect knowledge of teaching with the same respect as constructivists treat students' imperfect learning of science. The remainder of the paper explores this constructivist paradox, and suggests that‐like students' knowledge of science‐teachers' knowledge of constructivist science teaching is likely to grow through slow and gradual re‐formation of their established understanding of classroom theory and practice. 相似文献

Scientific argumentation is an important learning objective in science education. It is also an effective instructional approach to constructivist science learning. The implementation of argumentation in school settings requires science teachers, who are pivotal agents of transforming classroom practices, to develop sophisticated knowledge of argumentation. However, there is a lack of understanding about science teachers’ knowledge of argumentation, especially the dialogic meaning of argumentation. In this case study, we closely examine a high school physics teacher’s argumentation-related pedagogic content knowledge (PCK) in the context of dialogic argumentation. We synthesize the teacher’s performed PCK from his argumentation practices and narrated PCK from his reflection on the argumentation practices, from which we summarize his PCK of argumentation from the perspectives of orientation, instructional strategies, students, curriculum, and assessment. Finally, we describe the teacher’s perception and adaption of argumentation in his class. We also identity the barriers to argumentation implementation in this particular case and suggest solutions to overcome these barriers. 相似文献

We describe research carried out with a prospective secondary biology teacher, whom we shall call Miguel. The teacher’s conceptions
of the nature of science and of learning and teaching science were analyzed and compared with his classroom practice when
teaching science lessons. The data gathering procedures were interviews analyzed by means of cognitive maps and classroom
observations. The results reflected Miguel’s relativist conceptions of the nature of science that were consistent with his
constructivist orientation in learning and teaching. In the classroom, however, he followed a strategy of transmission of
external knowledge based exclusively on teacher explanations, the students being regarded as mere passive receptors of that
knowledge. Miguel’s classroom behavior was completely contrary to his conceptions, which were to reinforce the students’ alternative
ideas through debate, and not by means of teacher explanation. 相似文献

This is one of a series of studies conducted by a high school physics teacher, who used constructivist referents to plan and enact the curriculum, and to understand and improve the learning environment in his physics classes. Data were collected in the course of a two-year physics course including (a) repeated administrations of a classroom learning environment survey, (b) written essays on the topics of knowing, learning, and classroom learning environment, and (c) interviews. While there was a general trend for students to adopt more constructivist views of knowing and learning, there was also a small number who resisted to adapt to the constructivist learning environment in their physics course. Two case studies of individual students are used to illustrate the interactions of the learning environment, student understanding of scientific knowledge, and the nature of science, and students' views of their own learning. 相似文献

This is a longitudinal study of the thinking about teaching science of beginning Hong Kong primary teachers. The research explores how their thinking changed from pre-service teacher education through to their first year as classroom teachers. It takes a more holistic view of teacher thinking than typical in the literature considering the nature, interrelationships, and changes over time of four major aspects: conceptions, planning, teaching, and reflection. Positive findings were that the majority of participants became more constructivist in terms of their conceptions and practice of teaching, but they also tended to become more simplistic in planning and less coherent in thinking as they progressed from pre-service teacher education to beginning teachers in schools. 相似文献

A small group of Russian teachers who were interested in adopting aspects of the US science educational reform movement, participated in a constructivist science teaching project. Baseline data from translated classroom observations were scored using the science classroom observation rubric from the expert science teaching educational evaluation model (ESTEEM) and compared with a traditional (teacher centered) group of US science teachers and a group of US constructivist (student centered) science teachers. The purpose of the research is to investigate how Russian teachers who were beginning a US science education reform project compared with two US groups of science teachers, a traditional and a reform group. Analysis of variance was used to analyse the total rubric score and four categories for the Russian/traditional US and the Russian/constructivist US studies in order to examine closely the traditional and the constructivist teaching practises. In the first study US traditional teachers were statistically higher on 'facilitating the learning process' and 'context-specific pedagogy'. Russian teachers were higher on the 'content' category. In the second study the experienced constructivist US teachers were statistically higher on all four categories and the total rubric score. The educational culture of both countries is very traditional. However, the reform movement in science education has changed some US teachers, and is in the process of changing some Russian teachers. Both countries are working on the reform process. The results of this study provide baseline information on a small group of Russian teachers, who have chosen to be a part of the ideas contained in the US science education reform movement. The study also promotes the mutual understanding of both cultures among teachers, administrators, and researchers, which should ultimately form a bond for working together on common educational issues. 相似文献

This article is a study of a South African teacher educator's interpretations and approaches to implementing a constructivist approach to teaching. It examines his beliefs about teaching physical science to prospective teachers as it relates to his aligning his teaching with the new reform: outcomes-based education. The goals of the reform include emphasis on cooperative learning, a student-centered approach, and focus on teaching for conceptual understanding. Through observations, interviews, and documents (assignments for students, graded group assignments, and course outlines), I examined this teacher educator's interpretations and approaches to implementing constructivist curriculum and his understanding of the reform. The findings show that without confronting teachers' beliefs about teaching and learning, providing clear meaning of reforms, and facilitating in-depth professional development, the interpretation and implementation of reforms will be hindered. 相似文献

While constructivism has emerged as a major reform in science education from the last decade, wide-spread adoption of constructivist
practices in school laboratories and classrooms is yet to be achieved. If constructivist approaches are to be utilised more
widely, teachers will need to accept a more active and constructivist role in their own pedagogical learning. One experienced
junior science teacher was able to implement constructivist approaches in her classroom by using a personally constructed
metaphor to guide her practice.

The purpose of this article is to provide details about the beneficial processes the constructivist pedagogy has in the area of teaching science. No Child Left Behind could possibly cause detrimental effects to the science classroom and the constructivist teacher, so this essay tells how constructivist-based teaching influences students and their learning of science. 相似文献

This study, conducted from a constructivist perspective, examined the belief system of a prospective elementary teacher (Barbara) about science teaching and learning as she developed professional knowledge within the context of reflective science teacher education. From an analysis of interviews, observation, and written documents, I constructed a profile of Barbara's beliefs that consisted of three foundational and three dualistic beliefs. Her foundational beliefs concerned (a) the value of science and science teaching, (b) the nature of scientific concepts and goals of science instruction, and (c) control in the science classroom. Barbara held dualistic beliefs about (a) how children learn science, (b) the science students' role, and (c) the science teacher's role. Her dualistic beliefs formed two contradictory nests of beliefs. One nest, grounded in lifelong science learner experiences, reflected a didactic teaching orientation and predominantly guided her practice. The second nest, not well grounded in experience, embraced a hands‐on approach and predominantly guided her vision of practice. The findings accentuate the complexity and nestedness of teachers' belief systems and underscore the significance of identifying prospective teachers' beliefs, espoused and enacted, for designing teacher preparation programs. © 2003 Wiley Periodicals, Inc.

Although the concept of “rural” is difficult to define, rural science education provides the possibility for learning centered upon a strong connection to the local community. Rural American adolescents tend to be more religious than their urban counterparts and less accepting of evolution than their non-rural peers. Because the status and perception of evolutionary theory may be very different within the students’ lifeworlds and the subcultures of the science classroom and science itself, a cultural border crossing metaphor can be applied to evolution teaching and learning. This study examines how a teacher may serve as a cultural border crossing tour guide for students at a rural high school as they explore the concept of biological evolution in their high school biology class. Data collection entailed two formal teacher interviews, field note observations of two biology class periods each day for 16 days during the Evolution unit, individual interviews with 14 students, student evolution acceptance surveys, student evolution content tests, and classroom artifacts. The major findings center upon three themes regarding how this teacher and these students had largely positive evolution learning experiences even as some students continued to reject evolution. First, the teacher strategically positioned himself in two ways: using his unique “local” trusted position in the community and school and taking a position in which he did not personally represent science by instead consistently teaching evolution “according to scientists.” Second, his instruction honored local “rural” funds of knowledge with respect to local knowledge of nature and by treating students’ religious knowledge as a form of local expertise about one set of answers to questions also addressed by evolution. Third, the teacher served as a border crossing “tour guide” by helping students identify how the culture of science and the culture of their lifeworlds may differ with respect to evolutionary theory. Students negotiated the cultural borders for learning evolution in several ways, and different types of border crossings are described. The students respected the teacher’s apparent neutrality, sensitivity toward multiple positions, explicit attention to religion/evolution, and transparency of purposes for teaching evolution. These findings add to the current literature on rural science education by highlighting local funds of knowledge for evolution learning and how rural teachers may help students navigate seemingly hazardous scientific topics. The study’s findings also add to the current evolution education literature by examining how students’ religious perspectives may be respected as a form of expertise about questions of origins by allowing students to examine similarities and differences between scientific and religious approaches to questions of biological origins and change. 相似文献

The application of constructivist referents for teaching science has received some recent unwarranted criticism. To counter
some of the pedagogical criticisms, the teacher's role and actions within a Year 6 science classroom learning community are
described. In particular, my interpretation of two teaching episodes shows how the teacher helped a group of students transform
their understanding of electrical circuits. The teacher in this study mediated learning by monitoring the transformation of
student understanding and negotiating scientific practices—teaching practices which need to be illustrated more fully by researchers
to avoid further confusion about the application of idea-based social constructivism. I argue that the teacher's role, from
a social constructivist perspective, is to employ whatever strategies are needed to help students develop a deeper understanding
of canonical science. 相似文献

In this paper, we report an analysis of metaphors used by three science teachers in their classroom discourse and consider
the implications of this research for the image of science that students are likely to construct. Teacher beliefs about the
nature of science are implicit and entrenched and may be contrary to both contemporary philosophies of science and constructivist
theory. We argue that the presence of metaphors such ateaching as a journey, knowledge as object andteacher as pathfinder in teachers' classroom discourse signify the implicit existence of a powerful objectivist epistemology that governs teachers'
pedagogies. If students are to construct contemporary views of the nature of science and if constuctivist pedagogy is to develop
in the science classroom then science teachers need to reflect on their use of these role-determining objectivist metaphors. 相似文献

We investigated how Chinese physics teachers structured classroom discourse to support the cognitive and social aspects of inquiry-based science learning. Regarding the cognitive aspect, we examined to what extent the cognitive processes underlying the scientific skills and the disciplinary reasoning behind the content knowledge were taught. Regarding the social aspect, we examined how classroom discourse supported student learning in terms of students' opportunities to talk and interaction patterns. Our participants were 17 physics teachers who were actively engaged in teacher education programs in universities and professional development programs in local school districts. We analyzed one lesson video from each participating teacher. The results suggest both promises and challenges. Regarding the cognitive aspect of inquiry, the teachers in general recognized the importance of teaching the cognitive processes and disciplinary reasoning. However, they were less likely to address common intuitive ideas about science concepts and principles. Regarding the social aspect of inquiry, the teachers frequently interacted with students in class. However, it appeared that facilitating conversations among students and prompting students to talk about their own ideas are challenging. We discuss the implications of these findings for teacher education programs and professional development programs in China. 相似文献

Classroom stories of multicultural teaching and learning 总被引：3，自引：2，他引：1

This is the second of three papers based on a 20-month study of teaching and learning in a diverse classroom in a downtown community school in Toronto, Canada. The purpose of the research was to describe the details of teaching and learning in a multicultural classroom and to document successful strategies in working with immigrant and minority students. The three papers detail the process by which this focus on classroom life led to a critique of the literature and to a new way to think about multicultural teaching and learning, which I call 'narrative multiculturalism'. In this paper, I provide a sampling of stories that illustrate what contributed to my changing thinking about multiculturalism. Four short stories focus on a participant teacher in her school, in her classroom and in interaction with her students. The stories illuminate the complexity of multicultural teaching and qualities of narrative multiculturalism. In the analysis of the stories I explore multicultural understandings that developed from the experience of being in the classroom, being in relationship with a teacher participant, and our on-going dialogue. 相似文献
