This study was an exploration of what English language content was represented in a classroom in which English was taught as a foreign language (EFL). The purpose of this study was to explore the way EFL teachers represent English language content/constructs in a classroom setting. The motivation behind this exploration is to contribute to the understandings of EFL teachers' practices in classroom settings. Doyle's task framework was employed, specifically with the intention to map what content representations emerged out of the teachers' classroom practices. All in all, the teachers' classroom content representations were found to be entrenched with the idea of high-stakes test preparation in Turkey.

This study investigated the comparison between captured and revealed Pedagogical Content Knowledge (PCK) about graphs of motion. The aim of the study was to explore PCK when captured in a written format and discussions (captured PCK) and compare it to the PCK that the same teachers revealed in practice (revealed PCK) when teaching the topic. Four Grade 10 Physical sciences teachers were purposively and conveniently selected as participants of the study. Their PCK was captured through Content Representations (CoRes) and interviews. The revealed PCK on the other hand was gathered through lesson observations. The Topic Specific Pedagogical Content Knowledge (TSPCK) model was used as the framework that guided the analysis of the two manifestations of PCK. The focus was on teachers’ competences in the TSPCK components namely; learners’ prior knowledge including misconceptions, curricular saliency, what is difficult to teach, representations including analogies, and conceptual teaching strategies. The results of this study indicated that teachers’ competences in the TSPCK components varied. This was evident in both the captured and the revealed PCK. Thus it suggested that a teacher’s level of competence in one component is not necessarily an indication of his or her competence in the other components that define PCK, and subsequently in his/her overall captured or revealed PCK. Furthermore, the study suggested that the level of competence in a component in the captured PCK is not necessarily an indication of the level of competence within that component that the teacher would reveal during lesson presentation. The level may be the same, slightly different (higher or lower) or even be drastically different in the lesson than suggested by the captured PCK. A concluding remark was then made that teachers’ captured PCK is not necessarily a true reflection of the PCK they reveal during lesson presentation and that different instruments must be used to reflect on and assess teachers’ PCK in a topic. / Dissertation (MEd)--University of Pretoria, 2017. / Science, Mathematics and Technology Education / MEd / Unrestricted

This study investigated the relationship between teachers' pedagogical content knowledge (PCK) about electrostatics and learners' performance in the topic. Two in-service and two pre-service physical science teachers, together with their learners, agreed to participate in the study. The PCK of the teachers was viewed as two manifestations; the personal PCK, which is static in nature and the enacted PCK, which is dynamic. A content representation (CoRe) tool and lesson plans were used to collect data that reflected the personal PCK of the teachers. The data for the enacted PCK was collected using classroom observations, and video stimulated recall (VSR) interviews. A topic specific PCK model was adopted as the framework for this study. The model asserts that specific content is transformed for instruction through five components, namely; learners' prior knowledge, curricular saliency, what is difficult to teach, representations including analogies, and conceptual teaching strategies. Guided by the model, I developed two rubrics to assess and quantify the quality of the teachers' personal and enacted PCK on a four-point scale. Learners, on the other hand, wrote a test developed specifically for this study which explored their performance in the fundamental concepts chosen for this study. The performance of the learners was then related to the personal and the enacted PCK of the teachers separately. The results revealed that the personal and the enacted PCK of the teachers, as well as the performance of the learners, varied across fundamental concepts of electrostatics. The variations in the personal and enacted PCK provided empirical evidence that supports the notion that PCK has a concept specific nature. The results also showed that the performance of the learners was better related to the enacted PCK of the teachers compared to the personal PCK. These results imply that it is important to make teaching practice the centre of pre-service teacher education given the direct impact of enacted PCK on learning. Furthermore, exploring PCK at concept level reveals the strengths and weaknesses of the concepts. As such, pre-service teacher education and in-service teacher professional development may be tailored in a manner that addresses the concepts that require intervention. / Thesis (PhD)--University of Pretoria, 2020. / Science, Mathematics and Technology Education / PhD / Unrestricted

Thesis (M.Ed. (Mathematics)) ---University of Limpopo, 2016 / This research explored the pedagogical content knowledge (PCK) of algebra as held by a group of senior phase teachers in Limpopo Province, South Africa. Sixty-one teachers from different districts in the province participated in this study. This qualitative study used a case study design. Data was collected using a test and content representation (CoRe) matrix. The results were analysed through analysis of narratives. The study revealed that most of the teachers could not identify the main concepts that are taught in algebra. It was discovered that some could not differentiate between algebra and arithmetic. The findings also point out that the teachers had inadequate knowledge of algebra subject matter. The participants were able to identify some of the concepts that learners were supposed to do in the next grades. The findings revealed that most of the participants did not know the importance of teaching algebra. It was revealed that most participants could not identify the learners‘ difficulties; they could not specify the procedures they followed when teaching the identified main concepts in algebra, or give reasons for using those procedures. Furthermore, they could not specify factors that influenced their teaching. However, they were able to indicate different methods they used to assess learners‘ understanding. It was concluded that these teachers had inadequate PCK of senior phase algebra. The study recommends development programmes for both subject matter knowledge and PCK for practising teachers. Keywords: pedagogical content knowledge, content representations (CoRes), algebra, senior phase mathematics teachers.
