教师教学的教育重建模式

PCK是学科教学知识(Pedagogical Content Know ledge)的简称,是教师知识范畴中使教学最有效的知识。为了研究PCK产生了一种新的研究模式。这种模式被称为"教师教学的教育重建"(ERTE)模式,它代表了研究科学教师PCK的结构框架,它是一个庞大但是之前又未涉及的研究领域。基于此,从PCK的定义到ERTE模式作介绍,以期进一步促进教师教学的有效性,提高教学质量。     

Pedagogical Content Knowledge Development and Pre-Service Physics Teacher Education: A Case Study

This paper addresses the question of how to develop prospective teachers' pedagogical content knowledge (PCK) in science teacher education. The main focus is on the knowledge transformation process and on the cognitive strategies used to shift prospective teachers' explanations within the domain of modelling thermal physical phenomena. This study investigates the development of PCK within a group of 28 pre-service physics teachers during the first semester of their two-year post-graduate teacher education program. It focuses on the central issue of the relationships between observable phenomena, like macroscopic thermal properties of matter and their interpretation and/or explanation in terms of corpuscular characteristics and/or thermodynamics theory. The strategy is based on the consideration that knowledge transformation is not a one-way process from subject matter knowledge to pedagogical content knowledge, as literature suggests, but a bidirectional process involving deepening of subject matter knowledge and increasing awareness of pedagogical issues.     

教师学科教学知识:本质、特征与结构

教师学科教学知识(Pedagogical Content Knowledge)是教师研究的新焦点。自这一概念提出以来(Shulman,1986),其内涵与结构不断演变。教师PCK是教师关于如何将自己所知道的学科内容以学生易理解的方式加工、转化给学生的知识。它具有与内容相关;基于经验反思;有实践性;个体性以及情境性的特征。结构上,研究者基于Shulman(1986)的两个主要成分予以扩展;它是一个综合体;与其他教师知识类型紧密关联。值得注意的是,特定教师群体的特定主题PCK是日后研究的生长点。     

论小学科学教师PCK的内涵及其发展策略

学科教学知识(PCK)是教师知识的核心,发展PCK是教师专业发展的重要途径。文章阐述小学科学教师PCK的内涵,即教师为适应不同能力和兴趣的小学生,在将特定科学知识转化为学生易于理解的课堂教学形式时所使用的知识,它由小学科学课程知识、学习者知识、教学策略知识和学习评价知识构成。小学科学教师PCK的发展策略主要有:根据PCK内涵进行反思;加强专业阅读,进一步学习科学知识和科学教育知识;在学习共同体成员的交流中建构PCK。     

Teacher pedagogical constructions: a reconfiguration of pedagogical content knowledge

A brief review of the history of pedagogical content knowledge reveals various definitions and conceptualizations of the construct, as well as some conceptual problems. A new conceptualization—teacher pedagogical constructions—is offered to address some of the problems associated with PCK. Seven assertions that comprise the new conceptualization are presented, explained and defended. These are: (1) PCK represents personal and private knowledge; (2) PCK is a collection of basic units called teacher pedagogical constructions; (3) teacher pedagogical constructions result mainly from planning, but also from the interactive and post‐active phases of teaching; (4) pedagogical constructions result from an inventive process that is influenced by the interaction of knowledge and beliefs from different categories; (5) pedagogical constructions constitute both a generalized event‐based and a story‐based kind of memory; (6) pedagogical constructions are topic specific; and (7) pedagogical constructions are (or should ideally be) labeled in multiple interesting ways that connect them to other categories and subcategories of teacher knowledge and beliefs. The proposed definition results from a reconceptualization of the nature of PCK as originally proposed, taking the results of major later studies and conceptualizations of PCK into consideration, appropriating new ideas about the structure of memory, and undertaking a reanalysis and presentation of data from a previous study. The article calls for viewing PCK as neither a subcategory of subject matter (subject matter knowledge for teaching) nor as a general generic form of knowledge. It presents a view of PCK as a collection of teacher professional constructions, as a form of knowledge that preserves the planning and wisdom of practice that the teacher acquires when repeatedly teaching a certain topic. Viewing PCK as a collection of TPCs, more precisely defining it, clarifying its relations to other knowledge and beliefs entities, and speculating about its development should facilitate future investigations of PCK.     

Examining primary schools' physical education coordinators' pedagogical content knowledge of games: are we just playing as this?

A detailed insight into how the current educational climate influences the pedagogical decisions made by primary school teachers when teaching games is limited. Studies examining the pedagogical content knowledge (PCK) of teachers within physical education have revealed its close relationship with specific forms of subject knowledge. In recognition of this, Veal and MaKinster's framework of general, domain and topic-specific PCK was employed to examine 12 primary school teachers' PCK of games. It was concluded that when personal experiences of pedagogy and content knowledge are unchallenged and reinforced by teachers' training and continuing professional development (CPD) programmes, very narrow topic-specific PCK results. This PCK was characterised bythe inseparable paring of constricted pedagogical strategies and limited content knowledge. When teachers do not integrate this very narrow topic-specific PCK with other types of PCK, it has significant repercussions upon the planned curriculum and learning experiences offered to pupils.     

Preparing the Next Generation of Science Teacher Educators: A Model for Developing PCK for Teaching Science Teachers

Science education doctoral programs often fail to address a critical piece—the explicit attention to the preparation of future science teacher educators. In this article, we argue that, in addition to developing skills and a knowledge base for research, doctoral students must be given the opportunity to observe, practice, and reflect on the pedagogical knowledge necessary to instruct science teachers. In particular, we contend that the construct of pedagogical content knowledge (PCK) can be adapted to the context of knowledge for teaching science teachers. We use the PCK construct to propose a model for the development of knowledge for teaching science teachers, grounded in our experiences as doctoral students and faculty mentors. We end by recommending a vision for doctoral preparation and a new standard to be included in the ASTE Professional Knowledge Standards for Science Teacher Educators.     

Teacher pedagogical content knowledge,practice, and student achievement†

ABSTRACT

In this exploratory study, we attempted to measure potential changes in teacher knowledge and practice as a result of an intervention, as well as trace such changes through a theoretical path of influence that could inform a model of teacher professional knowledge. We created an instrument to measure pedagogical content knowledge (PCK), studied the impact of a two-year professional development intervention, explored the relationships among teacher variables to attempt to validate a model of teacher professional knowledge, and examined the relationship of teacher professional knowledge and classroom practice on student achievement. Teacher professional knowledge and skill was measured in terms of academic content knowledge (ACK), general pedagogical knowledge (GenPK), PCK and teacher practice. Our PCK instrument identified two factors within PCK: PCK-content knowledge and PCK-pedagogical knowledge. Teacher gains existed for all variables. Only GenPK had a significant relationship to teacher practice. ACK was the only variable that explained a substantial portion of student achievement. Our findings provide empirical evidence that we interpret through the lens of the model of teacher professional knowledge and skill, including PCK [Gess-Newsome, J. (2015). A model of teacher professional knowledge and skill including PCK: Results of the thinking from the PCK summit. In A. Berry, P. Friedrichsen, & J. Loughran (Eds.), Re-examining pedagogical content knowledge in science education (pp. 28–42).

Real-World Applications and Instructional Representations Among Prospective Elementary Science Teachers

This paper explores new elementary teachers' instructional representations and how these are related to their science subject matter knowledge. One pair of prospective elementary teachers studied here exhibited a well-integrated, principled, and scientifically accurate understanding of the science they were teaching. The other pair exhibited less scientifically accurate and integrated knowledge. The pair with stronger subject matter knowledge developed instructional representations that were more scientifically and pedagogically appropriate. A perspective on one aspect of pedagogical content knowledge—knowledge of instructional representations—is presented. Real-world applications are hypothesized to play a crucial mediating role for elementary teachers. The paper concludes with a discussion of implications for elementary science teacher educators and researchers, including the importance of attending to how prospective teachers apply science knowledge to real-world situations. Parts of this work were presented at the 2000 AERA and NARST meetings.     

Not a stale metaphor: the continued relevance of pedagogical content knowledge for science research and education

Recently, theorists have raised concerns that pedagogical content knowledge (PCK) has become “a stale metaphor” that disregards diversity and equity, offers little to help teachers address students’ misconceptions, and portrays knowledge as “in the head” versus in practice. We refute these notions using grounded theory to specify ways one 7th-grade science teacher enacted PCK to advance student learning. With the definition of PCK as knowledge at the intersection of content and teaching, we utilised a framework for science PCK to explore instructional decision-making. Interviews conducted over three years revealed specific ways the teacher enacted PCK by designing and delivering instruction built on each of the seven conceptual science PCK components. The teacher enacted PCK to plan and deliver instruction that was responsive, adaptive, and considerate of changing needs of students and the changing classroom landscape. She infused PCK into instructional decision-making, instructional interactions, and mentoring of a student teacher, modelling the translation of educational theory into practice and habits of mind necessary for expert teaching. This enactment actively refutes Settlage’s critiques, and depicts PCK as a vibrant and effective stance for teaching that enhances learning.     

Subject-matter knowledge and knowledge about students as sources of teacher presentations of the subject-matter

Pedagogical content knowledge is made up of several components. In this paper we concentrate on one of these: teachers' planned presentations of the subject-matter. We deal with two main sources of this component of pedagogical content knowledge: knowledge about the subject-matter and knowledge about students. Illustrations are given in two mathematical domains: functions and undefined mathematical operations. The paper concludes with a discussion of the nature of teachers' knowledge and the interconnections between the three constructs: subject-matter knowledge, knowledge about students, and knowledge about ways of presenting the subject-matter.     

Knowledge Integration in Science Teaching: Analysing Teachers' Knowledge Development

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.     

Teaching teachers to teach Boris: a framework for mathematics teacher educator pedagogical content knowledge

The notion of pedagogical content knowledge (PCK) was posited in the context of school teaching and the knowledge used by teachers teaching school students. It has been examined for a number of discipline areas, notably mathematics. There are, however, other teaching contexts, including those of teacher educators, whose students are pre-service teachers (PSTs). The content these teacher educators teach is not subject discipline knowledge (or not solely), but the PCK for teaching a subject discipline. What knowledge do teacher educators use as they teach PCK? This paper presents a framework for the PCK required of mathematics teacher educators as they work to develop PSTs’ PCK for teaching mathematics. The framework builds on existing research into PCK and categorises aspects of the work of teacher education. The framework’s usefulness is examined by studying the PCK used by the first author in building PSTs’ understanding of mathematics teacher PCK.     

Interaction Between Science Teaching Orientation and Pedagogical Content Knowledge Components

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.     

Promoting the development of teacher professional knowledge: Integrating content and pedagogy in teacher education

The study investigates the explicit and integrated presentation of pedagogical content knowledge (PCK), pedagogical knowledge (PK), and content knowledge (CK) in teacher education. We compare learning environments to study whether only presenting PK and CK is sufficient for PCK development, whether only presenting PCK is sufficient for PK and CK development, and whether PCK development is affected by integrating PCK, PK and CK. We find that only presenting two knowledge domains to students is insufficient to develop the third one, and integrating knowledge domains does not impact PCK development.

我国PCK研究取向的审视

教师的学科教学知识(PCK)是教师将自己所知道的学科内容以学生易懂的方式加工、转化、表达并传授给学生的知识。目前它已成为我国教师知识研究中的热点课题。理性审视这股"研究热"的背后,不难发现该领域的研究在学科化、本土化和科学化等方面还需要不断加以改进和完善。     

Expansion of Biology Teachers’ Pedagogical Content Knowledge (PCK) During a Long-Term Professional Development Program

Experienced teachers possess a unique teaching knowledge comprised of an inter-related set of knowledge and beliefs that gives direction and justification to a teacher’s actions. This study examined the expansion of two components of pedagogical content knowledge (PCK) of three in-service teachers in the course of a professional development program aimed at designing new teaching and learning materials suggested by the teachers themselves. The research presents an enlargement of previous PCK representations by focusing on a detailed representation of two main PCK domains: teaching and learning, including ten PCK components that emerged in the course of data analysis. This representation enabled revealing the unique PCK held by each teacher and to characterize the expansion of the two components of the participating teachers’ PCK during the long-term professional development program. Retention of major parts of the expanded PCK a year after termination of the program implies that designing and implementing new teaching and learning materials based on the teachers’ experiences, needs, and knowledge in a workshop format accompanied by biology and science education courses might provide a powerful means for PCK expansion. We recommend that designers of professional development programs be aware of the unique PCK held by each teacher in order to promote meaningful professional development of each teacher. Moreover, the PCK representations that were identified in the course of this study enabled clarifying the “orientation toward teaching science” category of PCK which appears to be unclear in current literature.     

A Self-Study of a Thai Teacher Educator Developing a Better Understanding of PCK for Teaching about Teaching Science

In this study, I, the first author as a Thai teacher educator employed self-study as a research methodology to investigate my own understandings, questions, and curiosities about pedagogical content knowledge (PCK) for teaching science student teachers and the ways I engaged student teachers in a field-based science methods course designed to help them to develop their PCK. Qualitative data gathered included: the syllabi, handouts, work submitted by student teachers, student teachers’ journal entries, my journal entries, and video recordings of my classroom teaching. Data were analysed using an inductive process to identify ways in which I attempted to enhance student teachers’ PCK. The contributions of this study are insights generated to help teacher educators think about how to support and develop student teachers’ PCK. Some of these contributions are enhancing teacher educators’ PCK for teaching science teachers, developing PCK for teaching science, and designing a science methods course in science teacher preparation programmes.
