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

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

This paper examines science teachers' pedagogical content knowledge and ways in which that knowledge might be captured, articulated and portrayed to others. The research from which this paper is drawn has involved interviews with experienced science teachers in an attempt to make the tacit nature of their practice explicit. Initially, case methodology was envisaged as being a way of documenting these teachers' pedagogical content knowledge. However, over time, the form of knowledge and information that we were gathering and attempting to portray extended beyond that which could reasonably be described as being case-based. Hence we have developed an approach to articulation and portrayal based on what we call the CoRe (Content Representation) – which represents the particular content/topic of the science teaching – and PaP-eRs (Pedagogical and Professional experience Repertoire) – which help to illuminate specific aspects of the CoRe and therefore offer insights into pedagogical content knowledge itself. The results of this study offer new ways of conceptualising what pedagogical content knowledge is and how it might be captured, documented and disseminated.  相似文献

While a solid understanding of science content knowledge is important in developing expertise in science teaching, it is not necessarily a sufficient condition to teach science effectively in elementary schools. Teachers need to have the ability to transform their knowledge into forms learnable by students. Based on this perspective, the current study explored how science content knowledge was pedagogically transformed in Korean elementary classrooms. Data sources included video-recorded science lessons of five elementary teachers in a metropolitan city of Korea. The analysis of the data revealed that the Korean teachers often engaged in transforming science content knowledge by means of different semiotic modes, including language, pictures, materials, actions, and their complex combinations. Further, their representations of scientific knowledge were in diverse forms, such as personifications, analogies, quiz questions, pictorial models, diagrams, animations, real-life examples, hand demonstrations, videos, flash tools, and songs-and-dances. Future research involving a wider range of participants, such as students, content specialists, and teachers with weak and strong content understanding, was suggested to confirm the findings of this study and find more various ways of pedagogical transformation of science subject matter knowledge.  相似文献

Primary teacher preparation courses to need support students in developing not only science content knowledge, but also pedagogical knowledge appropriate to the effective translation and representation of subject matter for learners in classrooms. In the case of the generalist primary trainee, this constitutes a considerable challenge. This study explored how a group of 13 primary trainees developed subject and pedagogical knowledge during university‐based training as they investigated shadow production in a variety of contexts using cognitive conflict as a strategy for promoting conceptual change. By using a metacognitive approach, students analysed their own learning in response to increasing depth of conflict within a series of shadow investigations. The results indicate that the depth of conflict perceived by the learners in this study was instrumental in inducing conceptual change and generating pedagogical insight within the domain of light.  相似文献

Roussel De Carvalho uses the notion of superdiversity to draw attention to some of the pedagogical implications of teaching science in multicultural schools in cosmopolitan cities such as London. De Carvalho makes the case that if superdiverse classrooms exist then Science Initial Teacher Education has a role to play in helping future science teachers to become more knowledgeable and reflective about how to teach school students with a range of worldviews and religious beliefs. The aim of this paper is to take that proposition a step further by considering what the aims and content of a session in teacher education might be. The focus is on helping future teachers develop strategies to teach school students to think critically about the nature of science and what it means to have a scientific worldview. The paper draws on data gathered during an interview study with 28 students at five secondary schools in England. The data was analysed to discover students’ perceptions of science and their perceptions of the way that science responds to big questions about being human. The findings are used to inform a set of three strategies that teachers could use to help young people progress in their understanding of the nature of science. These strategies together with the conceptual framework that underpins them are used to develop a perspective on what kinds of pedagogical content knowledge teacher education might usefully provide.  相似文献

ABSTRACT

Tests 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

While there is a growing literature focused on doctoral preparation for teaching about science teaching, rarely have recommendations extended to preparation for teaching science content to teachers. We three doctoral students employ self-study as a research methodology to investigate our developing pedagogical content knowledge for teaching science to teachers during a mentored internship in an elementary teacher professional development program. With our mentor, we examine critical incidents in the experience that supported new insights about teaching teachers and about ways in which beginning teacher educators need to develop their existing pedagogical content knowledge for teaching science to students in order to teach science effectively to teachers. We emphasize ways in which doctoral internships can support this learning and how our respective cultures shaped our interactions with and perceptions of teachers as learners.  相似文献

This qualitative video study explores how two elementary school teachers taught for conceptual understanding throughout different phases of science inquiry. The teachers implemented teaching materials with a focus on learning science key concepts through the development of word knowledge. A framework for word knowledge was applied to examine the students’ level of word knowledge manifested in their talk. In this framework, highly developed knowledge of a word is conceptual knowledge. This includes understanding how the word is situated within a network of other words and ideas. The results suggest that students’ level of word knowledge develops toward conceptual knowledge when the students are required to apply the key concepts in their talk throughout all phases of inquiry. When the students become familiar with the key concepts through the initial inquiry activities, the students use the concepts as tools for furthering their conceptual understanding when they discuss their ideas and findings. However, conceptual understanding is not promoted when teachers do the talking for the students, rephrasing their responses into the correct answer or neglecting to address the students’ everyday perceptions of scientific phenomena.  相似文献

This paper tests the utility of a new sociocognitive frame for analysing the development of teachers' knowledge – the knowledge integration perspective (Linn, Eylon, & Davis, in press; Linn & Hsi, 2000). In doing so, the paper describes one prospective elementary teacher's developing knowledge and highlights its complexity. The prospective teacher demonstrates relatively well-integrated science subject matter knowledge, but she makes some problematic links to lessons and develops some instructional representations that show where she needs to distinguish between different scientific ideas. She also, however, links science concepts to appropriate real-world experiences, indicating that she has nascent useful pedagogical content knowledge. The paper discusses what teacher educators can learn about their learners from this analysis, argues for the utility of the knowledge integration perspective for conducting similar analyses, provides ideas to help science teacher educators apply the perspective easily as they teach their students, and points to areas ripe for future research.  相似文献

Researchers have shown a growing interest in science teachers’ professional knowledge in recent decades. The article focuses on how chemistry teachers impart chemical bonding, one of the most important topics covered in upper secondary school chemistry courses. Chemical bonding is primarily taught using models, which are key for understanding science. However, many studies have determined that the use of models in science education can contribute to students’ difficulties understanding the topic, and that students generally find chemical bonding a challenging topic. The aim of this study is to investigate teachers’ knowledge of teaching chemical bonding. The study focuses on three essential components of pedagogical content knowledge (PCK): (1) the students’ understanding, (2) representations, and (3) instructional strategies. We analyzed lesson plans about chemical bonding generated by 10 chemistry teachers with whom we also conducted semi-structured interviews about their teaching. Our results revealed that the teachers were generally unaware of how the representations of models they used affected student comprehension. The teachers had trouble specifying students’ difficulties in understanding. Moreover, most of the instructional strategies described were generic and insufficient for promoting student understanding. Additionally, the teachers’ rationale for choosing a specific representation or activity was seldom directed at addressing students’ understanding. Our results indicate that both PCK components require improvement, and suggest that the two components should be connected. Implications for the professional development of pre-service and in-service teachers are discussed.  相似文献

Abstract

Examining how teachers structure the activities in a unit and how they facilitate classroom discussion is important to understand how innovative technology-rich curricula work in the context of classroom instruction. This study compared 2 enactments of an inquiry curriculum, then examined students' learning outcomes in classes taught by 2 teachers. The quantitative data show that there were significant differences in the learning outcomes of students in classes of the 2 teachers. This study then examined classroom enactments by the 2 teachers to understand the differences in the learning outcomes. This research specifically focused on how teacher-led discussions (a) helped connect the activities within a curriculum unit and (b) enabled deeper conceptual understanding by helping students make connections between science concepts and principles. This study examined the role that teacher facilitation played in helping students focus on the relations between the various activities in the unit and the concepts that they were learning. The results point to important differences in the 2 enactments, helping to understand better what strategies might enable a deeper conceptual understanding of the science content.  相似文献

Reading the interesting article Discerning selective traditions in science education by Per Sund, which is published in this issue of CSSE, allows us to open the discussion on procedures for teaching science today. Clearly there is overlap between the teaching of science and other areas of knowledge. However, we must constantly develop new methods to teach and differentiate between science education and teaching science in response to the changing needs of our students, and we must analyze what role teachers and teacher educators play in both. We must continually examine the methods and concepts involved in developing pedagogical content knowledge in science teachers. Otherwise, the possibility that these routines, based on subjective traditions, prevent emerging processes of educational innovation. Modern science is an enormous field of knowledge in its own right, which is made more expansive when examined within the context of its place in society. We propose the need to design educative interactions around situations that involve science and society. Science education must provide students with all four dimensions of the cognitive process: factual knowledge, conceptual knowledge, procedural knowledge, and metacognitive knowledge. We can observe in classrooms at all levels of education that students understand the concepts better when they have the opportunity to apply the scientific knowledge in a personally relevant way. When students find value in practical exercises and they are provided opportunities to reinterpret their experiences, greater learning gains are achieved. In this sense, a key aspect of educational innovation is the change in teaching methodology. We need new tools to respond to new problems. A shift in teacher education is needed to realize the rewards of situating science questions in a societal context and opening classroom doors to active methodologies in science education to promote meaningful learning through meaningful teaching.  相似文献

This article examines teacher professional learning about pedagogy for teachers of students with severe intellectual disabilities within broader teacher education and pedagogical frameworks for this group of learners. The article presents and discusses findings from a USA–England research project, involving classroom observations and interviews with nine teachers of students with severe intellectual disabilities from four specialist public school settings, intended to explore teachers’ pedagogical decision-making and learning. The theoretical lens of situated learning and the conceptual lens of evidence-based practice are used to contextualise and examine the teachers’ views about the what, how and when they learn about pedagogical approaches and strategies. Teachers emphasised the situated and interactional nature of their learning, particularly highlighting the personal responses of students and their relationship with these students. They use this knowledge and understanding to adapt evidence-based strategies and programmes and inform their pedagogical decisions. This affords the concepts of ‘situated generalization’ and ‘practice based evidence’ an influential role in how teachers engage in the process of pedagogical decision-making. An implication for teacher educators is the need to support teachers in making connections of new pedagogical understandings and skills with the individual learning profiles and responses of their students with severe intellectual disabilities.  相似文献

The nature of science (NOS) has become a central goal of science education in many countries. This study refers to a developmental work research program, in which four fifth-grade elementary in-service teachers participated. It aimed to improve their understandings of NOS and their abilities to teach it effectively to their students. The 1-year-long, 2012–2013, program consisted of a series of activities to support teachers to develop their pedagogical content knowledge of NOS. In order to accomplish our goal, we enabled teacher-researchers to analyze their own discourse practices and to trace evidence of effective NOS teaching. Many studies indicate the importance of examining teachers’ discussions about science in the classroom, since it is teachers’ understanding of NOS reflected in these discussions that will have a vital impact on students’ learning. Our proposal is based on the assumption that reflecting on the ways people form meanings enables us to examine and seek alternative ways to communicate aspects of NOS during science lessons. The analysis of discourse data, which has been carried out with the teacher-researchers’ active participation, indicated that initially only a few aspects of NOS were implicitly incorporated in teacher-researchers’ instruction. As the program evolved, all teacher-researchers presented more informed views on targeted NOS aspects. On the whole, our discourse-focused professional development program with its participatory, explicit, and reflective character indicated the importance of involving teacher-researchers in analyzing their own talk. It is this involvement that results in obtaining a valuable awareness of aspects concerning pedagogical content knowledge of NOS teaching.  相似文献

Preservice Teachers' Knowledge of Difficulties in Decimal Numeration   总被引:1,自引:0,他引:1  
In this study we investigated preservice elementary school teachers' content knowledge and pedagogical content knowledge of decimal numeration. The preservice teachers completed a decimal comparison test, marked items they thought would be difficult for students, and explained why. Only about 80 percent of the sample tested as experts, indicating that a significant proportion of preservice teachers have inadequate content knowledge of decimals. Confusion about the size of decimals in relation to zero was a significant and unexpected difficulty, leading to concerns about the fragmentary nature of the preservice teachers' knowledge. Most preservice teachers were aware of longer-is-larger misconceptions in students, but had little awareness of shorter-is-larger misconceptions. Preservice teachers' explanations for the reasons students might have difficulty demonstrated that many are good at identifying features that make comparisons difficult but less able to explain why these cause trouble. Results point to the need for teacher education to emphasise content knowledge that integrates different aspects of number knowledge, and pedagogical content knowledge that includes a thorough understanding of common difficulties. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

The purpose of this case study is to delve into the complexities of how preservice science teachers’ science teaching orientations, viewed as an interrelated set of beliefs, interact with the other components of pedagogical content knowledge (PCK). Eight preservice science teachers participated in the study. Qualitative data were collected in the form of content representation, responses to an open-ended instrument, and semi-structured interviews. Preservice teachers’ orientation and PCK were analyzed deductively. Constant comparison analysis of how their orientation interacted with other PCK components revealed three major themes: (1) one’s purpose for science teaching determines the PCK component(s) with which it interacts, (2) a teacher’s beliefs about the nature of science do not directly interact with his/her PCK, unless those beliefs relate directly to the purposes of teaching science, and (3) beliefs about science teaching and learning mostly interact with knowledge of instructional strategies. Implications for science teacher education and research are discussed.  相似文献

This study was designed to enhance teachers' knowledge by constructing cases as part of a school-based professional development project in Taiwan. Cases, involving episodes and issues from real classroom events, were constructed collaboratively by a school-based team consisting of the researcher and four classroom teachers. The process of constructing cases, characterization of teachers' understanding of cases, and their skills for case writing were developed in the course of the study. In the process of constructing these cases, teachers improved their awareness of and their competence in dealing with the difficulties students encountered in the learning of mathematics; they enhanced their pedagogical content knowledge and their ability to reflect on classroom practices.  相似文献
