Teachers’ content-related knowledge is a key factor influencing the learning progress of students. Different models of content-related knowledge have been proposed by educational researchers; most of them take into account three categories: content knowledge, pedagogical content knowledge, and curricular knowledge. As there is no consensus about the empirical separability (i.e. empirical structure) of content-related knowledge yet, a total of 134 biology teachers from secondary schools completed three tests which were to capture each of the three categories of content-related knowledge. The empirical structure of content-related knowledge was analyzed by Rasch analysis, which suggests content-related knowledge to be composed of (1) content knowledge, (2) pedagogical content knowledge, and (3) curricular knowledge. Pedagogical content knowledge and curricular knowledge are highly related (rlatent?=?.70). The latent correlations between content knowledge and pedagogical content knowledge (rlatent?=?.48)—and curricular knowledge, respectively (rlatent?=?.35)—are moderate to low (all ps?<?.001). Beyond the empirical structure of content-related knowledge, different learning opportunities for teachers were investigated with regard to their relationship to content knowledge, pedagogical content knowledge, and curricular knowledge acquisition. Our results show that an in-depth training in teacher education, professional development, and teacher self-study are positively related to particular categories of content-related knowledge. Furthermore, our results indicate that teaching experience is negatively related to curricular knowledge, compared to no significant relationship with content knowledge and pedagogical content knowledge. 相似文献

ABSTRACTSystems’ thinking has become increasingly relevant not only in education for sustainable development but also in everyday life. Even if teachers know the dynamics and complexity of living systems in biology and geography, they might not be able to effectively explain it to students. Teachers need an understanding of systems and their behaviour (content knowledge), and they also need to know how systems thinking can be fostered in students (pedagogical content knowledge (PCK)). But the effective development of teachers’ professional knowledge in teaching systems thinking is empirically uncertain. From a larger study (SysThema) that investigated teaching systems thinking, this article reports the effects of the three different interventions (technical course, didactic course and mixed course) in student teachers’ PCK for teaching systems thinking. The results show that student teachers’ PCK for teaching systems thinking can be promoted in teacher education. The conclusion to be drawn from our findings is that a technically orientated course without didactical aspects seems to be less effective in fostering student teachers’ PCK for teaching systems thinking. The results inform educators in enhancing curricula of future academic track and non-academic track teacher education. 相似文献

This article analyzes the experiences of prospective secondary mathematics teachers during a teaching methods course, offered
prior to their student teaching, but involving actual teaching and reflexive analysis of this teaching. The study focuses
on the pedagogical difficulties that arose during their teaching, in which prospective teachers lacked pedagogical content
knowledge and skills. It also analyzes the experience of the course itself, which was aimed at scaffolding the work of prospective
teachers on developing their pedagogical content knowledge and skills. 相似文献

This article reports the development and application of two instruments for assessing science teachers’ pedagogical knowledge in the context of teaching higher‐order thinking: a Likert‐type research instrument, and an instrument that analyzes classroom observations. The rationale for developing these instruments and their main categories is described. One hundred and fifty Israeli science teachers replied to the Likert‐type questionnaire. Results show that biology teachers gained a significantly higher score than either physics or chemistry teachers, that junior high school teachers scored significantly higher than high school teachers, and that a significant negative correlation was found between final scores and teaching experience. Participants in the classroom observation study were 14 teachers who attended a one‐year professional development course for teaching higher‐order thinking. The instrument was sensitive in detecting progress in teachers’ pedagogical knowledge in several categories, such as: Frequency of tasks that required higher‐order thinking; The variety of thinking strategies that teachers addressed during their lessons; Engagement of students in metacognitive thinking; and Using the “language of thinking” in class. The implications of the findings for research and practice are described. 相似文献

Teaching experience has been identified as an important factor in pedagogical content knowledge (PCK) development. However, little is known about how experienced teachers may draw on their previous experience to facilitate their PCK development. This study examined how two experienced high school biology teachers approached the teaching of a newly introduced topic in the curriculum, polymerase chain reaction and their PCK development from the pre-lesson planning phase through the interactive phase to the post-lesson reflection phase. Multiple data sources included classroom observations, field notes, semi-structured interviews and classroom artefacts. It was found that the teachers’ previous experience informed their planning for teaching the new topic, but in qualitatively different ways. This, in turn, had a bearing on their new PCK development. Subject matter knowledge (SMK) can not only facilitate but may also hinder this development. Our findings identify two types of experienced teachers: those who can capitalise on their previous teaching experiences and SMK to develop new PCK and those who do not. The critical difference is whether in the lesson planning stage, the teacher shows the disposition to draw on a generalised mental framework that enables the teacher to capitalise on his existing SMK to develop new PCK. Helping teachers to acquire this disposition should be a focus for teacher training in light of continuous curriculum changes. 相似文献

Identifying Science Teachers’ Perceptions of Technological Pedagogical and Content Knowledge (TPACK)
Tzu-Chiang Lin Chin-Chung Tsai Ching Sing Chai Min-Hsien Lee 《Journal of Science Education and Technology》2013,22(3):325-336
The application of information and communication technology in instruction is highly emphasized in the contemporary education of science teachers. This paper hence aims to explore science teachers’ perceptions of technological pedagogical content knowledge (TPACK) addressing teachers’ perceptions of the affordances of technology application in instruction. A total of 222 pre- and in-service science teachers in Singapore were surveyed. Structural equation models analysis was utilized to examine the model of TPACK involving the seven factors of technological knowledge (TK), pedagogical knowledge (PK), content knowledge (CK), technological content knowledge (TCK), technological pedagogical knowledge (TPK), pedagogical content knowledge (PCK), as well as synthesized knowledge of technology, pedagogy, and content (TPC). The results confirm the seven-factor model and indicate that the science teachers’ perceived TPC significantly and positively correlated with all the other TPACK factors. This paper further reveals the relationships between the science teachers’ perceptions of TPACK and their demographic characteristics such as teaching experience, gender, and age. The findings indicate that female science teachers perceive higher self-confidence in pedagogical knowledge but lower self-confidence in technological knowledge than males. Further, female in-service science teachers’ perceptions of TK, TPK, TCK, and TPC significantly and negatively correlate with their age. 相似文献

Abstract Teachers and university professors hold strong, and often different, views on school subjects and academic disciplines. This paper explores the meanings of subjects and disciplines for teachers and university professors who have different subject or disciplinary affiliations as these emerge within discussions about curriculum in a professional development context. It describes a group of university professors and secondary school teachers who met to discuss new developments in research in the humanities and social sciences and their impact on school curriculum. The professors brought their expertise in their academic disciplines and their teaching experience to the conversations. Teachers brought their varied disciplinary knowledge, pedagogical content knowledge and a deep understanding of schools. They perceived their primary goal as making ‘translations’ and ‘transformations’ between university and school. There were many bridges to cross within these complex and multi‐layered conversations. The possibility of bridges was enhanced by sharing common experiences in dealing with dilemmas of teaching. However, it demonstrated the importance of exposing the key structures and arguments of the disciplines as a first step in building bridges among subject communities and between universities and schools. 相似文献

Teachers' self-concepts have shown correlations with the effectiveness of their teaching, but we know little about the development of their self-concepts. According to the generalized internal/external frames of reference (GI/E) model, social and dimensional achievement comparisons may affect not only students’ but also pre-service teachers’ self-concepts. Thus, we extended and applied this model to examine relations between estimates and self-concepts of 430 pre-service biology teachers’ professional knowledge in three domains: content knowledge (CK), pedagogical content knowledge (PCK), and pedagogical and psychological knowledge (PPK). Structural equation modelling provided strong support for the GI/E model’s capacity to explain teachers’ self-concepts: with positive paths from CK, PCK, and PPK to the corresponding self-concepts, indicating social comparison effects, and negative paths from CK and PPK test scores to the PPK and CK self-concepts, respectively, indicating dimensional comparison effects. In addition, CK was negatively related with the teachers’ PCK self-concept. The results are discussed in terms of their implications for both teacher education and the proposed GI/E model. 相似文献

This ethnographic research study investigated three elementary teachers’ perceived self-efficacy beliefs and their attitudes toward mobile technology-enhanced instruction. Using technological pedagogical content knowledge (TPACK) as a guiding theory, the authors sought to determine whether and how the three knowledge components that form the foundation of the TPACK framework– technological, pedagogical or content knowledge – have similar levels of influence on teachers’ language arts teaching practices. They also examined how each teacher incorporated iPad technologically enhanced pedagogical practices and made connections to their beliefs about the role of technology and education. Data collection consisted of classroom observation field notes, teacher interviews and teacher blogs. Findings reveal that the teachers’ attitudes toward the integration of iPad technology formed a basis for how they approached their pedagogy. Compared to their technological and content knowledge, teachers’ pedagogical knowledge and years of teaching experience strongly influenced their decisions regarding mobile technology integration. By the end of the study, all teachers identified stronger connections and awareness in relation to the components of TPACK. The implications of these findings will provide insight relevant to the development of professional development opportunities for teachers regarding TPACK that could ultimately lead to more successful technology integration by teachers. 相似文献

This study examined the similarities and differences in experienced secondary science teachers' planning, teaching, and reflecting on their teaching, when teaching in their science area of certification and when teaching in another science area. The study also focused on the influence of these teachers' content knowledge, pedagogical knowledge, and pedagogical content knowledge on their planning, teaching, and reflecting. Experienced teachers were observed and interviewed while teaching classes in their science area of certification, and in another science area they were teaching for the first or second time. Both similarities and differences in teaching were found in the two areas for all three teachers. For example, their planning and postlesson reflections were similar in both areas. In the interactive phase of teaching more differences were observed. Many aspects of their teaching resembled that of expert teachers in other studies. In the unfamiliar science area, the teachers sometimes acted like novice teachers. However, they were able to draw upon their pedagogical knowledge to provide a framework for their teaching in both science areas. Their wealth of pedagogical knowledge, and pedagogical content knowledge for general science topics, seemed to sustain them in whatever content they were teaching. Recommendations for further study and implications for teacher education are discussed. 相似文献

Quality mentoring is fundamental to preservice teacher education because of its potential to help student and novice teachers develop the academic and pedagogical knowledge and skills germane to successful induction into the profession. This study focused on Jordanian preservice primary teachers' perceptions of their mentoring experiences as these pertain to science teaching. The Mentoring for Effective Primary Science Teaching instrument was administered to 147 senior preservice primary teachers in a university in Jordan. The results indicated that the greater majority of participants did not experience effective mentoring toward creating a supportive and reflexive environment that would bolster their confidence in teaching science; further their understanding of primary science curriculum, and associated aims and school policies; help with developing their pedagogical knowledge; and/or furnish them with specific and targeted feedback and guidance to help improve their science teaching. Substantially more participants indicated that their mentors modeled what they perceived to be effective science teaching. The study argues for the need for science-specific mentoring for preservice primary teachers, and suggests a possible pathway for achieving such a model starting with those in-service primary teachers—much like those identified by participants in the present study—who are already effective in their science teaching. 相似文献

The welcome new attention paid to subject teaching should have bridged the old divide between pedagogical and disciplinary research. But this paper argues that the focus on subject, rather than disciplinary communities is part of the commodification of higher education; that what is needed to re-energise both teachers and students is an inclusive new model of disciplinary education based on an engaged community's processes and practices. Each discipline, it is proposed, will model differently its practices, knowledge creation and dissemination, its writing, its community. The model may change received ideas about the focus and central concerns of the discipline, and in modelling disciplinary learning will change teaching and assessment. The model will be discipline specific and, as such, will resist generic and imposed 'skills and outcomes' frameworks. Evolving out of practice, rather than an external agenda, it should link disciplinary and pedagogical research so that they are mutually informing and transforming. 相似文献

ABSTRACTTeachers’ professional knowledge is considered one of the most important predictors of instructional quality. According to Shulman, such professional knowledge includes content, pedagogical content and pedagogical knowledge. Although recent research shed some light on the structure of the dimensions of professional knowledge, little is known how teacher education impacts pre-service physics teachers’ professional knowledge. In an effort to address this issue, we examined the content, pedagogical content and pedagogical knowledge of N?=?200 pre-service physics teachers enrolled in different years of teacher education at 12 major teacher education universities in Germany. We used structural equation modelling (1) to examine the relations amongst pre-service physics teachers’ content, pedagogical content and pedagogical knowledge, (2) to explore how the three kinds of knowledge and their relations differ across different stages of teacher education and (3) to identify factors affecting the level of each component of professional knowledge. Our findings suggest that content, pedagogical content and pedagogical knowledge represent distinct types of knowledge. Furthermore, our findings show that in the first years of professional education, pedagogical content knowledge is more closely related with general pedagogical knowledge while in later years, it is more closely related with content knowledge, suggesting that it develops from a general knowledge about teaching and learning into knowledge about the teaching and learning of specific content. Finally, beyond school achievement and years of enrolment as predictors, we find in particular the amount of classroom observations to have a positive impact on the professional knowledge of pre-service physics teachers. 相似文献

Due to a program reform in Israel, experienced CS high-school teachers faced the need to master and teach a new programming paradigm. This situation served as an opportunity to explore the relationship between teachers' content knowledge (CK) and their pedagogical content knowledge (PCK). This article focuses on three case studies, with emphasis on one of them. Using observations and interviews, we examine how the teachers, we observed taught and what development of their teaching occurred as a result of their teaching experience, if at all. Our findings suggest that this situation creates a new hybrid state of teachers, which we term “regressed experts.” These teachers incorporate in their professional practice some elements typical of novices and some typical of experts. We also found that these teachers' experience, although established when teaching a different CK, serve as a leverage to improve their knowledge and understanding of aspects of the new content. 相似文献

This study investigated the relations between teachers’ pedagogical beliefs and students’ self-reported engagement in learning from texts with instructional pictures. Participants were the biology, geography, and German teachers of 46 classes (Grades 5-8) and their students. Teachers’ instructional behaviors and students’ engagement in learning from texts with instructional pictures were assessed by means of student ratings. Teachers’ beliefs about using texts with instructional pictures in their teaching were assessed by a self-report questionnaire. Results showed that the more teachers believed that students should be taught clear strategies on how to learn from texts with instructional pictures the more engagement was reported by their students. A multilevel mediation model showed that the association between teachers’ beliefs and students’ self-reported engagement was mediated by teachers’ perceived instructional behavior. 相似文献

This study explored the pedagogical content knowledge (PCK) and its development of four experienced biology teachers in the context of teaching school genetics. PCK was defined in terms of teacher content knowledge, pedagogical knowledge and knowledge of students’ preconceptions and learning difficulties. Data sources of teacher knowledge base included teacher-constructed concept maps, pre- and post-lesson teacher interviews, video-recorded genetics lessons, post-lesson teacher questionnaire and document analysis of teacher's reflective journals and students’ work samples. The results showed that the teachers’ individual PCK profiles consisted predominantly of declarative and procedural content knowledge in teaching basic genetics concepts. Conditional knowledge, which is a type of meta-knowledge for blending together declarative and procedural knowledge, was also demonstrated by some teachers. Furthermore, the teachers used topic-specific instructional strategies such as context-based teaching, illustrations, peer teaching, and analogies in diverse forms but failed to use physical models and individual or group student experimental activities to assist students’ internalization of the concepts. The finding that all four teachers lacked knowledge of students’ genetics-related preconceptions was equally significant. Formal university education, school context, journal reflection and professional development programmes were considered as contributing to the teachers’ continuing PCK development. Implications of the findings for biology teacher education are briefly discussed. 相似文献

ABSTRACT Case studies have pointed out that teachers’ disciplinary knowledge affects their pedagogy; however, the results are not consistent. There is a need for quantitative research to examine the relationship between teacher knowledge and practice, particularly in social studies where content-specific studies are mostly qualitative. The authors used history as an example and surveyed all public and private junior high school social studies teachers in Taiwan to examine if disciplinary backgrounds significantly affect teachers’ knowledge, conceptions about the discipline, and their teaching practices. Hierarchical linear modeling analyses show that disciplinary backgrounds significantly affect teachers’ subject matter knowledge and pedagogy. Evaluations of effect sizes suggest that academic backgrounds can serve as useful proxies for teacher recruitment. The results also indicate that nature-revealing courses affect teachers’ subject matter knowledge and pedagogy. 相似文献
