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.     

What do we know and where do we go? Formative assessment in developing student teachers’ professional learning of teaching science

In the context of teacher education, it could well be suggested that assessment activities that build on formative interactions between student teachers and teacher educators might offer new windows into better understanding teaching and learning. This paper presents findings from a study into a primary science teacher education initiative that seeks to build the foundations on which 24 primary science student teachers, through the use of formative assessment of their science teaching and learning, can begin developing their pedagogical content knowledge (PCK). In the project, formative assessment consists of activities used by teacher educators to stimulate interactions, self- and peer-assessment in order to provide insights into how student teachers develop their PCK during a semester. Content Representations (CoRes), were used as a tool to unpack the student teachers’ approach to teaching a science topic and the reasons for that approach. The results indicate that the use of CoRes, together with subsequent self-assessment and formative interactions with teacher educators and peers, do have the potential for PCK development for student teachers. The results further highlight the need for developing reliable and valid tools for capturing and assessing student teachers’ PCK in pre-service teacher education.     

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.

Exploring the Development of Pre-Service Science Elementary Teachers’ Pedagogical Content Knowledge

This paper explores how a group of pre-service elementary science student teachers came to understand the development of their Pedagogical Content Knowledge (PCK) over the course of a semester??s study in a science methods course. At the start of the semester, PCK was introduced to them as an academic construct and as a conceptual tool that they could use to plan for, and assess, the development of their professional knowledge and practice as beginning science teachers. All participants were provided with a tool known as a CoRe (Content Representation) and the manner in which they worked with the CoRe was such that it supported them in planning for and assessing their own learning about teaching elementary science through a focus on the development of their PCK. Through analysis of data derived from the application of a CoRe based methodology (modified and adapted for this study) to the teaching of the science topic of Air, participants?? reasons for, confidence in, and perceived meaningfulness of their learning about science teaching could be examined. In so doing, the nature of participants?? PCK development over time was made explicit. The results illustrate real possibilities for ways of enhancing student teachers?? ongoing professional learning in teacher preparation and offer a window into how the nature of PCK in pre-service education might be better understood and developed.     

Foundations of Science Literacy: Efficacy of a Preschool Professional Development Program in Science on Classroom Instruction,Teachers’ Pedagogical Content Knowledge,and Children’s Observations and Predictions

Young children are able to benefit from early science teaching but many preschool teachers have not had opportunities to deepen their own understanding of science or to develop their pedagogical content knowledge (PCK) in relation to specific science topics and concepts. This study presents the results of efficacy research on Foundations of Science Literacy (FSL), a comprehensive professional development program designed to support teachers’ knowledge of early childhood science; their PCK around 2 physical science topics (water, and balls and ramps); and their abilities to plan, facilitate, and assess young children’s learning during inquiry-based science explorations. Research Findings: In a randomized trial with 142 preschool teachers and 1,004 4-year-old children, FSL teachers demonstrated significantly higher quality science teaching in general and greater PCK in the 2 physical science topics than did teachers in comparison classrooms. Furthermore, children in FSL classrooms performed significantly better than children in comparison classrooms on tasks involving floating and sinking, and an instrumental variable analysis suggests that the quality of classroom science instruction mediated the relationship between teacher participation in FSL and student outcomes. Practice or Policy: Findings support the use of comprehensive early science professional development programs designed to bolster teacher knowledge and PCK.     

Science teachers' pedagogical content knowledge development during enactment of socioscientific curriculum materials

The purpose of this study is to provide insight into short-term professionalization of teachers regarding teaching socioscientific issues (SSI). The study aimed to capture the development of science teachers' pedagogical content knowledge (PCK) for SSI teaching by enacting specially designed SSI curriculum materials. The study also explores indicators of stronger and weaker development of PCK for SSI teaching. Thirty teachers from four countries (Cyprus, Israel, Norway, and Spain) used one module (30–60 min lesson) of SSI materials. The data were collected through: (a) lesson preparation form (PCK-before), (b) lesson reflection form (PCK-after), (c) lesson observation table (PCK-in-action). The data analysis was based on the PCK model of Magnusson, Krajcik, and Borko (1999). Strong development of PCK for SSI teaching includes “Strong interconnections between the PCK components,” “Understanding of students' difficulties in SSI learning,” “Suggesting appropriate instructional strategies,” and “Focusing equally on science content and SSI skills.” Our findings point to the importance of these aspects of PCK development for SSI teaching. We argue that when professional development programs and curriculum materials focus on developing these aspects, they will contribute to strong PCK development for SSI teaching. The findings regarding the development in the components of PCK for SSI provide compelling evidence that science teachers can develop aspects of their PCK for SSI with the use of a single module. Most of the teachers developed their knowledge about students' understanding of science and instructional strategies. The recognition of student difficulties made the teacher consider specific teaching strategies which are in line with the learning objectives. There is an evident link between the development of PCK in instructional strategies and students' understanding of science for SSI teaching.     

Enhancing the Practicum Experience for Pre-service Chemistry Teachers Through Collaborative CoRe Design with Mentor Teachers

This paper reports findings from an ongoing study exploring how the Content Representation (CoRe) design can be used as a tool to help chemistry student teachers begin acquiring the professional knowledge required to become expert chemistry teachers. Phase 2 of the study, reported in this paper, investigated how collaboration with school-based mentors (associate teachers) on teaching practice (practicum) might impact on this process and student teachers’ development of their pedagogical content knowledge (PCK). The collaboration involved identifying and discussing pedagogical issues related to a practicum-teaching topic using a student teacher’s draft CoRe as a starting point and ongoing focus for the professional dialogue. Practicum offered an opportunity for aspects of student teachers’ PCK, as embodied in their draft CoRes, to be explored and expanded upon in classroom programmes with the support and input of associate teachers. The findings were influenced by different contextual factors; however, the student teachers found their CoRes to be very useful frameworks for engaging in focussed professional dialogue with their teaching mentors. They valued the expertise, currency of knowledge and mentoring of their associates and reported positively about the contribution this support made to their PCK development via the CoRe design process and the transformation of the CoRe into classroom teaching.     

Student teachers’ pedagogical content knowledge for teaching systems thinking: effects of different interventions

ABSTRACT

Systems’ 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.     

TELPS: A method for analysing mathematics pre-service teachers' Pedagogical Content Knowledge

A pre-service teacher's Pedagogical Content Knowledge (PCK) and their personal constructs of teaching develop throughout their teacher education program. PCK integrates generic pedagogical knowledge, mathematical teaching methodology and knowledge of the discipline of mathematics and this paper reports on a survey that can be used to assess a pre-service teacher's PCK. TELPS (Teacher Education Lesson Plan Survey) was developed to determine the PCK of pre-service teachers during their teacher education program. TELPS is shown to analyse pre-service teachers' PCK with some indication that the pre-service teacher's development of PCK can be observed.     

On-Site Pedagogical Content Knowledge Development

Experiences and reflection have long been regarded as a foundation for pedagogical content knowledge (PCK) development. However, little is known about how experienced teachers develop their PCK via reflection-in-action during their moment-to-moment classroom instruction. Drawing upon data sources including classroom observations, semi-structured interviews and stimulated recall interviews based on lesson videos, this study examined instances when four experienced teachers were found to invent new instructional strategies/representations on the spot during the lesson (referred to as on-site PCK development) in their first attempts at teaching a new topic. The study documented the moment-to-moment experiences of the teachers, including their reconstructed thought processes associated with these instances of on-site PCK development. An explanatory model of a three-step process comprising a stimulus, an integration process and a response was advanced to account for the on-site PCK development observed among the teachers. Three categories of stimulus that triggered on-site PCK development were identified. Factors influencing the integration process and, hence, the resulting response, included teachers’ subject matter knowledge of the new topic, their general pedagogical knowledge and their knowledge of student learning difficulties/prior knowledge related to the new topic. Implications for teacher professional development in terms of how to enhance teachers’ on-site PCK development are discussed.     

Explaining Student Achievement: the Influence of Teachers’ Pedagogical Content Knowledge in Statistics

Statistics is an increasingly important component of the mathematics curriculum. StatSmart was a project intended to influence middle-years students’ learning outcomes in statistics through the provision of appropriate professional learning opportunities and technology to teachers. Participating students in grade 5/6 to grade 9 undertook three tests, a pre-test, a post-test and a longitudinal retention test over a period of 2 years. Their teachers completed a survey that included items measuring pedagogical content knowledge (PCK) for teaching statistics. Despite the development of valid instruments to measure both student and teacher content knowledge and teachers’ PCK, linking teachers’ knowledge directly to students’ learning outcomes has proved elusive. Multilevel modelling of results from 789 students for whom there were 3 completed tests and measures from their teachers indicated that students’ outcomes were influenced positively by their initial teacher’s PCK. Extended participation of teachers in the project also appeared to reduce negative effects of changing teachers.     

Exploring Biology Teachers’ Pedagogical Content Knowledge in the Teaching of Genetics in Swaziland Science Classrooms

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.     

STEAM教师学科教学知识的基本构成与建构逻辑

教师学科教学知识(PCK)的形成是STEAM教育的发展之基。STEAM教师PCK是教师面对具体的跨学科的内容主题时,所特有的将不同学科的知识和技术转化为学生易于理解的教学形式的整合性知识,具有知识范畴的跨学科性、知识来源的实践性和知识形成的融合性等特点。通过对已有PCK研究的梳理,结合STEAM教育的特征,STEAM教师PCK可分为跨学科内容知识、教学对象知识、教学情境知识和教学策略知识。在此基础上,STEAM教师PCK的建构逻辑:一是立足理论性学习为教师建构PCK打“地基”,促进公共性PCK向个体性PCK转化;二是基于经验性学习为教师建构PCK竖“框架”,推动内隐性PCK向实践性PCK转化;三是通过实践性学习为教师建构PCK添“砖瓦”,实现陈述性PCK向程序性PCK转化。     

Capturing student teachers’ pedagogical content knowledge (PCK) using CoRes and digital technology

During the last decades, digital technologies have become more common in providing opportunities for reflection and in-depth analysis of classroom practices and have afforded new ways of organising teacher education. In particular, videotaped lessons have proven to be a valuable tool for capturing teaching episodes, subsequent reflection and development of student teachers’ professional knowledge, here referred to as ‘pedagogical content knowledge’ (PCK). The aim of this project was to investigate how the use of the reflective tool, content representations (CoRes) in combination with video and associated digital tools might be used as a means for capturing student teachers’ professional knowledge of practice. In the study we explore how a group of 24 secondary science student teachers were provided with Content Representations (CoRe) and video annotations to support their reflection-on-action during their practicum. Video annotations, alongside a written reflection of critical incidents in the student teachers’ teaching constituted data for analysis. Our findings suggest that the different tools enabled the student teachers to connect captured examples of teaching instances with theoretical issues, and in this way offered the ability to see as well as to analyse their teaching practice. As such, the CoRe, together with the video annotation tool, proved to be successful in scaffolding and structuring student teachers’ reflection-on-action, allowing them to connect their reflections to components of PCK and further to articulate connections between these components.     

Building Pedagogical Content Knowledge within Professional Learning Communities: An approach to counteracting regional education inequality

Pedagogical Content Knowledge (PCK) and Professional Learning Community (PLC) are key notions to help understand teacher development for the benefit of student learning. Less understood is the contribution of PLC to PCK. This paper considers the Teaching and Research System in China to be a nationally institutionalised PLC for in-service teacher education. Building on quantitative analysis of a sample of 10,202 teachers, the paper concludes that participation in teaching and research activities within PLCs benefits teachers’ PCK. The paper also concludes that building PCK through the Teaching and Research System has potential to counteract regional education inequality.

Middle School Teachers’ Use of Mathematics to Make Sense of Student Solutions to Proportional Reasoning Problems

Mathematics teacher education aims to improve teachers’ use of mathematical knowledge to support teaching and learning, an aspect of pedagogical content knowledge (PCK). In this study, we interviewed teachers to understand how they used mathematics to make sense of student solutions to proportional reasoning problems. The larger purpose was to find accurate ways of categorizing teachers’ ability to do this vital aspect of teaching and thereby to inform assessment, teacher education, and professional development. We conjectured that teachers’ PCK for proportional reasoning could be reliably described in terms of attention to quantitative meanings in story problem contexts and in terms of understanding naïve forms of proportional reasoning. Instead, our findings reveal that individual teachers used a variety of means to make sense of (1) cognitively similar student solutions to different tasks and (2) mathematically related steps of a student solution within a single task. These findings illustrate the complexity of PCK for the topic of proportional reasoning and suggest the limits of what can be inferred about teacher knowledge from teachers’ evaluations of student solutions. We discuss implications for teacher education and assessment.     

Identifying pathways of teachers’ PCK development

This paper describes a method of analysing teacher growth in the context of science education. It focuses on the identification of pathways in the development of secondary school teachers’ pedagogical content knowledge (PCK) by the use of the interconnected model of teachers’ professional growth (IMTPG).The teachers (n = 12) participated in a one-year action research project focused on their individual concerns related to teaching science. The use of the IMTPG revealed that teachers use different pathways of learning to develop different aspects of their PCK. For each PCK component, three distinct pathways could be identified, two of which clearly were associated with professional growth. When examining these two pathways in detail, it was found that (1) teachers learned about new instructional strategies and assessment methods mostly through literature reviews and discussions with peers and (2) teachers who analyzed and reflected on student learning as it happened in their classrooms developed understandings that helped them to select and apply instructional strategies to further promote student learning. Both the analytical method as well as the identification of the different developmental pathways help to better understand teacher development in the context of classroom practices.
