The purpose of this study is to investigate physics teachers’ (TPCK) and their learners’ achievement in electricity. A purposive sample of 42 Grade 11 physics teachers and 1423 learners participated in the study. An explanatory mixed method research design was employed in the study to collect data. A survey questionnaire (PTTPCKQ), consisting of six-point Likert scale questions, was answered by participating teachers. Similarly, their learners responded to a confirmatory questionnaire (LCPTTPCKQ). The learners also responded to the Electricity Learning Confirmatory Questionnaire (LELCQ) and wrote an achievement test called Learner Electricity Achievement Test (LEAT). The data collected was analysed both quantitatively and qualitatively. Quantitatively, it was found that a positive, statistically significant relationship existed between physics teachers’ experience and their learners’ achievement [Spearman’s rho (42) = .39, p = .011] as well as physics teachers’ TPCK and their qualifications [Spearman’s rho (42) = .33, p = .003]. There was also a positive statistical relationship between physics teachers’ TPCK and learner achievement, yet this was not statistically significant. There were positive, statistically significant relationships between all the constructs of the physics teachers’ TPCK and their TPCK from the analysis of the PTTPCKQ. There were positive statistically significant relationships between all the constructs of the physics teachers’ TPCK and their TPCK, according to the analysis of the LCPTTPCKQ. Furthermore, comparing the learners’ responses on the LCTTPCKQ and their teachers’ responses on the PTTPCKQ, it was found that both learners and teachers provided similar responses for all the constructs of TPCK except TCK. Qualitative data analysis further revealed that the technologies used by these teachers were PhET Simulations, YouTube Videos, Power Point Presentations, Interactive White Boards, and Mindset Videos. Finally, between 12.9% and 5.2% of the learners reported that their teachers had neglected to teach some sections of the electricity in the curriculum. / Mathematical Sciences / Ph. D.

This report surveys existing literature in order to determine how best to implement target language captioned video in a classroom of a particular context: a Korean church in the U.S. whose members desire to improve their English language ability for the purpose of sharing the gospel of resurrection in English. In order to gain insight into the benefits and limitations of target language captioned video on second language listening comprehension and vocabulary acquisition and thus how to use the learning tool optimally, literature is reviewed regarding word knowledge, processing strategies, and reported gains or effects of the use of captioned video. Then, incorporating the information gleaned from the literature, two sample lesson plans are presented utilizing the C-Channel English testimony videos as the primary tool for instruction. / text

The democratic era in South Africa has led to the introduction of a wide-ranging series of teaching and learning policies aimed at school reform. The study aimed at establishing how these policies are implemented by educators in selected schools. Qualitative and quantitative methods were used to gather information from educators, members of the School Management Teams and learners through in-depth individual and focus group interviews as the main data collection methods. Critical discourse analysis was used to examine participants‟ spoken words and the content of relevant documents such as lesson plans in detail. Comparisons were drawn and similarities identified through the coding, categorisation and condensation of data. The researcher interpreted the displayed data. A discussion of the main themes was presented and supported by quotations by participants. Findings indicate that there have been only few changes in terms of how educators teach; some educators conceded that they had not changed the way they teach since the introduction of new curriculum and assessment policies. The role played by learning outcomes in teachers‟ lesson planning was uneven. Members of School Management Teams demonstrated diverse views on teaching and learning policies. Learners who are taught in their home language encounter few difficulties in learning; this is not the case with learners who are taught through medium of a second language and thus lack the necessary language proficiency necessary for academic achievement. A shift from teacher-centred to learner-centred approaches to teaching is still required: that is, a shift from teaching to learning to enhance thinking and reflection which accommodates and draws on learners‟ prior knowledge and experiences. Class sizes should be reduced to enable effective educator and learner interaction. Educators‟ interest, tolerance, innovativeness and competency in the subject matter will help sustain learners‟ interest in the learning activities. Policy makers should explore professional development from viewpoint of the participating educators in order to identify the most effective strategies to support and change educators‟ classroom practice where necessary. / Curriculum and Instructional Studies / D.
