This purpose of this study was to examine the ways in which three prospective teachers who had early opportunities to teach science would approach representing science content within the context of their student teaching experiences. The study is framed in the literature on pedagogical content knowledge and learning to teach. A situated perspective on cognition is applied to better understand the influence of context and the role of the cooperating teacher. The three participants were enrolled in an experimental teacher preparation program designed to enhance the teaching of science at the elementary level. Qualitative case study design guided the collection, organization, and analysis of data. Multiple forms of data associated with student teachers' content representations were collected, including audiotaped planning and reflection interviews, written lesson plans and reflections, and videotaped teaching experiences. Broad analysis categories were developed and refined around the subconstructs of content representation (i.e., knowledge of instructional strategies that promote learning and knowledge of students and their requirements for meaningful science learning). Findings suggest that when prospective teachers are provided with opportunities to apply and reflect substantively on their developing considerations for supporting children's science learning, they are able to maintain a subject matter emphasis. However, in the absence of such opportunities, student teachers abandon their subject matter emphasis, even when they have had extensive background and experiences addressing subject‐specific considerations for teaching and learning. © 2002 Wiley Periodicals, Inc.

This study (a) assessed the influence of an integrated nature of science (NOS) instructional intervention on inservice secondary science teachers' understandings, retention of those understandings, and their NOS instructional planning and practices; and (b) examined factors that mediated the translation of teachers' NOS understandings into practice. Nineteen teachers participated in an intensive, 6-week NOS course, which concluded with teachers developing plans to address NOS in their classrooms. Next, 6 participants were observed as they implemented their instructional plans. Data sources included pretest, posttest, and delayed-test NOS assessments, classroom observations, and several teacher-generated artifacts. The NOS course was effective in helping teachers develop informed NOS conceptions and retain those understandings 5 months after its conclusion. Teachers met with challenges and successes as they attempted to address NOS instructionally. The translation of NOS conceptions into practice was primarily mediated by the very nature of teachers' newly acquired NOS understandings, which were situated within the science contents, contexts, and experiences in which they were developed (i.e. the NOS course); thus, limiting participants' abilities to transfer their understandings into novel contexts and contents. The results helped build a model of the sources of science teachers' pedagogical content knowledge for teaching about NOS in content-rich contexts. 相似文献

The Science Teachers Learning from Lesson Analysis (STeLLA) project is a videobased analysis‐of‐practice PD program aimed at improving teacher and student learning at the upper elementary level. The PD program developed and utilized two “lenses,” a Science Content Storyline Lens and a Student Thinking Lens, to help teachers analyze science teaching and learning and to improve teaching practices in this year‐long program. Participants included 48 teachers (n = 32 experimental, n = 16 control) and 1,490 students. The STeLLA program significantly improved teachers' science content knowledge and their ability to analyze science teaching. Notably, the STeLLA teachers further increased their classroom use of science teaching strategies associated with both lenses while their students increased their science content knowledge. Multi‐level HLM analyses linked higher average gains in student learning with teachers' science content knowledge, teachers' pedagogical content knowledge about student thinking, and teaching practices aimed at improving the coherence of the science content storyline. This paper highlights the importance of the science content storyline in the STeLLA program and discusses its potential significance in science teaching and professional development more broadly. © 2011 Wiley Periodicals, Inc., J Res Sci Teach 48: 117–148, 2011 相似文献

Earlier reports have shown that prospective teachers' conceptions about teaching science to a high degree are resistant and do not change substantially during the teacher‐training programme. In our investigation we elucidate the prospective teachers' initial conceptions about pupils' understanding of science and mathematics. We applied ‘The Lesson Preparation Method' and used a phenomenographic approach in order to reveal the range of conceptions that the prospective teachers hold. A third of the prospective teachers did not consider pupils' conceptions when planning lessons. The rest of the 32 participants expressed awareness; some of the prospective teachers even referred to subject‐specific teaching experience. Also regarding the prospective teachers' conceptions about pupils' knowledge and beliefs, as well as about pupils' difficulties, there was a significant diversity. By raising these issues about pedagogical content knowledge the prospective teachers' conceptions can be extended and developed during the education. 相似文献

Grounded in teacher professional development addressing the intersection of student diversity and content area instruction, this study examined school teachers' pedagogical reasoning complexity as they reflected on their second language learners' science problem solving abilities using both home and school contexts. Teachers responded to interview questions after watching a video of one of their students engaged in a science problem solving task. Over a 5-year period, 206 teacher interviews were conducted with a total of 133 teachers. Results indicated significant differences across the dimensions of pedagogical reasoning complexity as teachers expressed both deficit and resource oriented thinking. 相似文献

Models play an important role in science education. However, previous research has revealed that science teachers' content knowledge, curricular knowledge, and pedagogical content knowledge about models and modelling are often incomplete or inadequate. A research project was conducted that aimed at promoting and gaining an understanding of the development of beginning science teachers' knowledge in this area. The teachers, who were enrolled in a teacher's training programme, participated in a special course on models and modelling, and conducted a research project in their classes about this theme. The data gathered in this project support the discussion to the extent that both the activities of the course and the conducting of and reflection on their research projects contributed to the development of teachers' knowledge. From the results, we propose some guidelines for educational researchers interested in this area. 相似文献

ABSTRACTTests convey messages about what to teach and how to assess. Both of these dimensions may either broaden or become more uniform and narrow as a consequence of high-stakes testing. This study aimed to investigate how Swedish science teachers were influenced by national, high-stakes testing in science, specifically focusing on instances where teachers’ pedagogical practices were broadened and/or narrowed. The research design is qualitative thematic analysis of focus group data, from group discussions with Swedish science teachers. The total sample consists of six teachers, who participated in 12 focus group discussion during three consecutive years. Findings suggest that the national tests influence teachers' pedagogical practice by being used as a substitute for the national curriculum. Since the teachers do not want their students to fail the tests, they implement new content that is introduced by the tests and thereby broaden their existing practice. However, when this new content is not seen as a legitimate part of teachers' established teaching traditions, the interpretation and implementation of this content may replicate the operationalisations made by the test developers, even though these operationalisations are restricted by demands for standardisation and reliable scoring. Consequently, the tests simultaneously broaden and narrow teachers’ pedagogical practices. 相似文献

This study examines Finnish and English primary student teachers' ideas when planning to teach a physics topic during their science education studies. Many primary student teachers lack sufficient subject knowledge, which prevents them from constructing the scientific pedagogical content knowledge that enables them to concentrate on pupils' thinking and process skills needed in a physics topic. Therefore they will have problems constructing learning environments that encourage pupils to take active control of their learning. In order to develop effective pedagogical content knowledge it is of the utmost importance that the science educators responsible for physics courses pay special attention to the promotion of favourable attitudes towards the teaching of physics topics. This can be done by focusing on how to teach some basic familiar topics. Quality, not quantity, is important in focusing on both subject knowledge and pedagogical content knowledge. The construction of pedagogical content knowledge is a complex interrelationship of attitudes, subject, and pedagogical knowledge. All three of them need to be developed to enable students to confidently and effectively teach young children. 相似文献

In search of pedagogical content knowledge in science: Developing ways of articulating and documenting professional practice 总被引：2，自引：0，他引：2
This study examines the development of ways of documenting and portraying science teachers' pedagogical content knowledge (PCK). As a result of a longitudinal study into science teachers' pedagogical content knowledge, a method is developed for capturing and portraying PCK that comprises two important elements. The first is linked to the particular science content, termed Content Representation (CoRe), and the second is linked to teaching practice, termed Professional and Pedagogical experience Repertoire (PaP‐eR). Through this approach new understandings of PCK emerge that are of interest in terms of both academic (knowledge building about PCK) and teaching perspectives. This study includes a full CoRe and one PaP‐eR and fully demonstrates how these two elements interact to begin to portray science teachers' pedagogical content knowledge. © 2004 Wiley Periodicals, Inc.

The purpose of this study was to describe the knowledge base of a group of science teachers in terms of their knowledge of the structure, function, and development of their disciplines, and their understanding of the nature of science. The study also aimed to relate the teachers' knowledge base to their level of education, years of teaching experience, and the class level(s) that they teach. Twenty inservice science teachers were selected to respond to a modified version of the Views on Science–Technology–Society (VOSTS) questionnaire to assess their understanding of the nature of science. The teachers then constructed concept maps and were interviewed. The concept maps were scored and the interviews analyzed to assess teachers' knowledge of the structure, function, and development of their disciplines. The teachers' knowledge base was found to be lacking in all respects. Teachers held several naive views about the nature of science and did not demonstrate adequate knowledge and understanding of the structure, function, and development of their disciplines. Moreover, the teachers' knowledge base did not relate to their years of teaching experience, the class level(s) that they teach, and their level of education. It was reasoned that teacher preparation programs are not helping teachers develop the knowledge base needed for teaching science. © 1997 John Wiley & Sons, Inc.

This study examined Malaysian science teachers' pedagogical content knowledge (PCK) of selected physics concepts. The two components of PCK investigated were (i) knowledge of students' understanding, conceptions and misconceptions of topics, and (ii) knowledge of strategies and representations for teaching particular topics. The participants were 12 trainee teachers from various academic science backgrounds attending a one-year postgraduate teacher-training course. They were interviewed on selected basic concepts in physics that are found in the Malaysian Integrated Science curriculum for lower secondary level. The findings showed that trainee teachers' PCK for promoting conceptual understanding is limited. They lacked the ability to transform their understanding of basic concepts in physics required to teach lower secondary school science pupils. The trainees' level of content knowledge affected their awareness of pupils' likely misconceptions. Consequently, the trainees were unable to employ the appropriate teaching strategies required to explain the scientific ideas. This study provides some pedagogical implications for the training of science teachers. 相似文献

The new Advanced Placement (AP) Computer Science (CS) Principles course increases the need for quality CS teachers and thus the need for professional development (PD). This article presents the results of a 2-year study investigating how teachers teaching the AP CS Principles course for the first time used online PD material. Our results showed that the teaching and computing background of teachers had a significant impact on the teachers' need for and use of online PD material. More specifically, novice CS teachers needed and used PD for developing their pedagogical content knowledge (PCK). Non-CS teachers needed and used PD materials emphasizing content knowledge. Experienced CS teachers believed they had little need for PD even though they were teaching a new course. Our study makes three recommendations for designing effective online PD for CS teachers: match PD to teachers' background, align PD with the course curriculum, and use effective motivational design to enhance teacher engagement.

Theories associated with teacher knowledge suggest that teachers transform subject content knowledge into pedagogical content knowledge in teaching to enhance the content comprehensibility. It is assumed that the connection between teacher content knowledge and curriculum is characterized by the content knowledge transformation. This study, using an interpretive research method combined with cognitive knowledge elicitation and mapping approaches, examined the subject-pedagogical content knowledge transformation process that was associated with the teachers' curricular decision-making in secondary physical education. Findings indicated that the teachers shared a common subject content knowledge base but demonstrated a personalized pedagogical content knowledge repertoire, suggesting that the teachers' pedagogical content knowledge was personally constructed even though they shared a subject content knowledge base. The classroom curriculum was closely connected to the pedagogical content knowledge base. In addition, the teachers' curricular decisions regarding content inclusion/exclusion were primarily based on their perceptions of student learning abilities. The findings may imply that enhancement of prospective teachers' pedagogical content knowledge should be emphasized in teacher preparation programs because it serves as a bridge linking the subject content knowledge with the curriculum delivered in classrooms. 相似文献

Technological pedagogical content knowledge TPACK refers to the knowledge set that teachers currently use to further improve the quality of their teaching and assist their students in learning. Several TPACK models have been proposed, either for discussing TPACK's possible composition or its practical applications. Considering that teachers' practical experiences should also be critical to the development of those teachers' knowledge, this study invited a research panel (six researchers) and an expert panel (54 science‐related educators) to propose and validate the framework of TPACK‐practical. After two rounds of anonymous communications that followed Delphi survey techniques, a total of eight dimensions of TPACK‐practical and corresponding indicators were identified and rated as having high levels of importance. Among these knowledge dimensions, the knowledge of direct information and communication technology uses for enhancing teachers' professionalism and students' conceptual comprehension was rated with a high level of importance. Also, disciplinary differences were found to exist between the different groups of experts. Biology teachers showed significantly higher ratings across all knowledge dimensions, whereas physics teachers' ratings were comparatively low. Such findings suggest that the structure and content of subject matter shapes not only the way they teach with technology but also the thinking logics they build longitudinally from their learning experiences. 相似文献

This paper uses cultural historical activity theory to examine the interactions between the choices primary teachers make in the use of practical activities in their teaching of science and the purposes they attribute to these; their emotions, background and beliefs; and the construction of their identities as teachers of science. It draws on four case studies of science lessons taught over a term by four exemplary teachers of primary science. The data collected includes video recordings of science lessons, interviews with each teacher and some of their students, student work, teachers?? planning documents and observation notes. In this paper, we examine the reflexive relationship between emotion and identity, and the teachers?? objectives for their students?? learning; the purposes (scientific and social) the teachers attributed to practical activities; and the ways in which the teachers incorporated practical activities into their lessons. The findings suggest that it is not enough to address content knowledge, pedagogy and pedagogical content knowledge in teacher education, but that efforts also need to be made to influence prospective primary teachers?? identities as scientific thinkers and their emotional commitment to their students?? learning of science. 相似文献

This study examined the pedagogical content knowledge of experienced and novice chemical demonstrators. It specifically delineates the nature of the declarative knowledge associated with science teachers' pedagogical content knowledge. Science teachers who (1) teach abstract concepts in chemistry, (2) have a strong interest in using demonstrations as a science teaching strategy, and (3) have high and low levels of experience conducting chemical demonstrations participated in the study. Clinical interviews were used to probe teachers' pedagogical content knowledge. The findings suggest that the experienced chemical demonstrators possess a greater representational and adaptational repertoire for teaching fundamental concepts in chemistry than novices. They also appeared to be more cognizant of the complexity of chemical demonstrations, how these complexities may interfere with learning, and how simplified variations of chemical demonstrations can promote concept learning. The implications for teacher education programs are discussed. 相似文献

In this study, five elementary teachers and a university researcher developed and implemented problem‐based learning (PBL) experiences in the context of science teaching and learning. Collaborative inquiry was adopted as a methodology, while a variety of qualitative methods were used to examine the engagement and development of teachers’ pedagogical content knowledge (PCK). A PCK model is used as a framework to examine teachers’ professional knowledge growth in areas such as orientations to teaching science, knowledge of science curriculum, knowledge of students’ understanding of science, knowledge of assessment, and knowledge of instructional strategies. Implications for how teachers may be supported when adopting instructional innovations are discussed. 相似文献

A previous study highlighted the perception among secondary science teachers that they faced considerable challenges to their pedagogical practice when teaching unfamiliar areas of the curriculum; for example, when teaching out of subject specialism. One of the major challenges cited by the teachers was being able to give appropriate and effective science teaching explanations in the classroom. Since talking in order to explain science is at the centre of what science teachers do, this concern is a significant one for teacher educators. This article considers some of the methodological issues about how to investigate the relationship between teachers’ subject content knowledge and their pedagogical practice. The research outlined focuses on a single science teacher’s practice in giving science teaching explanations when teaching in and out of subject specialism. Although the findings from a single case are of limited value in terms of generalisability, this study adds to the discussion about future research into the relationship between teachers’ professional knowledge bases and their pedagogical practices. 相似文献
