Depth Analysis

We examined the interactions among pedagogical content knowledge (PCK) components of novice and experienced chemistry teachers in teaching reaction rate and chemical equilibrium topics in this qualitative multiple-case design study. For this aim, three chemistry teachers who had different levels of teaching experience in chemistry teaching were selected through a process of purposeful sampling. Multiple types of data were gathered through more than two months. In order to collect and triangulate data, a card-sorting activity, a Content Representation (CoRe) tool, semi-structured interviews, observation of instruction, and field notes were utilized. Data were analyzed through three approaches: in-depth analysis of explicit PCK, the enumerative approach, and constant comparative methods. The results revealed eight characteristics of the interactions of the PCK components: (a) the novice teacher's orientations towards science, in contrast to the experienced teachers’, were more broad and non-specific, which impeded the interactions among the components, (b) the interplay of the PCK components was idiosyncratic and topic specific, (c) the novice teacher's PCK maps were fragmented while the experienced teachers’ PCK maps were integrated, (d) the experienced teachers, in contrast to the novice teacher, interacted more than two PCK components in most of their teaching fragments, (e) knowledge of learner, knowledge of curriculum and knowledge of instructional strategies were central in the interplays of all teacher maps, (f) the experienced teachers were more successful than the novice teacher in translating their knowledge into practice in terms of the integration among PCK components, (g) teacher self-efficacy appeared to play a role in their use of PCK components and constructing interactions among them, and (h) all teachers taught the same topics with similar lesson plans and the same instructional materials; however, they differed in terms of how they connect the PCK components. Implications and suggestions for teacher education and science education research are presented.

This study aims to analyze the profile of technological pedagogical and content knowledge (TPACK) chemistry teachers at one of the schools in Jakarta. The criteria for the teachers analyzed are professional teachers who have been certified and have more than 20 years of teaching experience. The method used in this study is a qualitative descriptive research method. The data sources were collected through the TPACK questionnaire referring to the Schmid instrument (2009), lesson plan analysis, observation of the learning process, and interviews. The results show that chemistry teachers can apply learning methods that vary each meeting according to the characteristics of acid-base material. The teacher also utilizes technology information & communication (ICT) based learning media to simplify and clarify material delivery. It can be concluded that teachers have pedagogical content knowledge (PCK) and technological content knowledge (TCK). The use of ICT media such as interactive power points, videos and mobile phones to support selected learning methods, shows that teachers are also competent in technological pedagogical knowledge (TPK). The results of the study concluded that the teacher had integrated all TPACK components into acid-base learning.

Survey Measure

While various quantitative measures for assessing teachers’ technological pedagogical content knowledge (TPACK) have developed rapidly, few studies to date have comprehensively validated the structure of TPACK through various criteria of validity especially for content specific areas. In this paper, we examined how the TPACK survey measure is aligned with the TPACK lesson plan measure and how they are related to the measure of epistemological beliefs about chemistry. The participants were 280 Chinese preservice chemistry teachers enrolled in a university in China. Both exploratory and confirmatory factory analyses were performed on the TPACK survey measure to help to establish validity, including considerations for convergent and discriminant validity. This was followed by the invariance test to examine factorial validity as related to gender. To establish the predictive validity of TPACK, the relationships among teachers’ epistemological beliefs, TPACK, and their capacity for planning technology-integrated lessons were also examined. Overall, the results showed that all four types of validity looked at in this study (i.e., convergent, discriminant, factorial, and predictive) were satisfactorily established. Implications for TPACK research and teacher education are also discussed.

Pedagogical Content

This paper presents a qualitative cross-level study with a focus on prospective and in-service teachers’ pedagogical content knowledge (PCK) of redox reactions in Germany. The objective was to investigate and analyze the differences in PCK between those in pre-service teacher education and those working as teachers. The sample included four different groups: bachelor’s students, master’s students, graduate teacher trainees, and in-service teachers. Data were collected by an online questionnaire and semi-structured interviews. The online questionnaire was developed based on misconceptions and learning difficulties regarding redox reactions. Sixty-two participants answered the questionnaire and the interviews were carried out with twelve participants. The results revealed that teaching experience makes a difference. Pre-service teachers described quite traditional and content-focused approaches while experienced teachers emphasized the application of the content. Experienced teachers showed a more developed repertoire of instructional strategies. Participants differed also in their knowledge about learners and the curriculum. Concerning assessment, practices were at a quite general pedagogical knowledge level and not domain-specific. Although teacher education in Germany includes several chances for internships, it is suggested that central aspects of teachers’ PCK start to develop and settle only when they begin to work as teachers. To avoid perpetuating traditional practices, investment in continuous professional development is needed.
