The purpose of this study was to explore the Zimbabwean physics teachers’ interpretation of the Advanced Level Physics curriculum. The study was motivated by the teachers’ lacklustre approach to adopting new practices and the poor alignment of their understanding with the practice envisaged by developers (Fullan, 2007:39; Ndawi&Maravanyika, 2011:68). Zimbabwean Advanced Level physics teachers are in this predicament, as evidenced by the low numbers of undergraduate students and the misconceptions displayed by physics learners enrolling for first year university work in physics-related disciplines (Kazembe and Musarandega, 2012:4). Having an idea of physics teachers’ perceptions, experiences and current practices with regard to the revised Advanced Level physics curriculum maybe fertile ground for intervention measures and policy decisions. To obtain a more holistic picture of the physics teachers’ practices, a mixed methods research approach using the convergent parallel research design was adopted for the study. A closed survey questionnaire was used to solicit for information from 56 physics teachers in four educational provinces. Random sampling was used to select the survey respondents. From these participants, 10 were purposively selected for face-to-face in-depth structured interviews basing on their availability and accessibility. Ten schemes of work,one from each interviewed teacher, for one school term and six past examination practical paper 4 question papers were collected and analysed using a document analysis guide. Quantitative data was analysed using descriptive statistics and chi-square, whereas qualitative data was collated into themes for discussion purposes. The findings of the study reveal that the physics teachers have embraced the ideals of the physics curriculum and adapted it to their operating context through the reiterative interpretation process to construct personal meaning. The teachers are mainly utilising teacher-centred approaches to impart knowledge to the learners which is not consistent with the physics curriculum anticipations of using learner-centred approaches. The physics teachers are superficially interpreting the physics curriculum.The physics teachers need to embrace the learner centred teaching approach andbe empowered to enhance their curriculum interpretation and teaching practices through staff development. / Curriculum and Instructional Studies / D.

Few South African students pass Grade 12 Physical Science with symbols required by university science, engineering and health science faculties. A large number of students who sit for Grade 12 Physical Science and Mathematics exams pass with symbols that are well below those required by the mainstream science courses at South African universities. Most South African universities have introduced Science Foundation Programmes with the aim of upgrading those students who failed to obtain university entrance symbols in the relevant subjects. Amongst the courses offered in Science Foundation Programmes is Foundation Physics. This study investigates the influence of Foundation Physics in order to find out if the programmes in different institutions are successful in empowering the students who failed to get the required entrance mark in Grade 12 Physical Science. Four South African Historically Black universities participated in this study. The Force and Motion Conceptual Evaluation test (FMCE) (Thornton & Sokoloff, 1998) and mechanics marks were used to assess students' understanding of Newtonian mechanics. Data was analyzed from socio-cultural perspective. A total of 194 students participated in the study. Two groups of students were compared, i.e. those who did Foundation Physics (Foundation group) and those who did not do Foundation Physics (non-Foundation group). The students were tested after they had completed a mechanics module, which forms a great foundation of Physics I (Introductory Physics). Two focus group interviews were held with selected Foundation and non-Foundation students per institution. Students voiced their experiences in Physics I and Foundation Physics. Students were chosen to represent focus groups according to their performance in the FMCE test. Mechanics class performances were also used to evaluate students' performance. In order to establish how Foundation Physics is taught, Foundation Physics Lecturer interviews were conducted at all four institutions. Analysis of data showed that both Foundation and non-Foundation students performed equally in Physics I mechanics module. Foundation group performed better than the non-Foundation group in the FMCE, which is a conceptual test. Foundation Physics lecturers indicated that there were some differences in the way mechanics was taught in Physics I and Foundation Physics. These differences affected students' performance. The lecturers also indicated that there was minimal interaction between Physics I lecturers and Foundation Physics lecturers pertaining to the teaching of the two courses. What influence does Foundation Physics have on the performance of students in Physics I? This study found that students who did Foundation Physics performed better than those who did not do Foundation Physics in conceptual questions and both the groups perform equally in questions that require memorizing and calculations. This implies that Foundation Physics courses are empowering the students to perform well in Physics I. However, as it is evidenced by this research, the differences in assessment in Physics I and Foundation Physics courses in some institutions hampers Foundation Physics students' learning, because the questions asked require them to memorize without understanding, something they are not used to. The researcher recommends that Foundation Physics staff and Physics I staff should start communicating, not only about how Foundation Physics should be run as was the case in the past, but also on how best Physics I should be run. This might help in making sure that the two courses are assessed similarly at one institution. / Mathematics, Science and Technology Education / D. Phil.

This study explored if there are differing beliefs and attitudes regarding working with students of multicultural backgrounds based on the content area specialties (i.e. biology, chemistry, Earth science and physics) of in-service secondary science teachers. The study was mixed methods and conducted in two parts. The first part focused on the use of quantitative statistical analysis to review the results of 152 respondents to a 54 Likert questions on the Survey on Multiculturalism in the Science Classroom (SMSC). The statistical analysis was followed up with qualitative analysis of interviews with 12 in-service science teachers representing the different content areas. Quantitative findings indicated that biology and Earth science teachers demonstrated similar patterns of responses in terms of comparative statistical analysis, network correlation diagrams, and general responses to the Likert items from the SMSC. Of the four content area groups, physics teachers demonstrated the greatest difference in their responses regarding multiculturalism. The results also showed that the beliefs and attitudes of chemistry teachers were correlated with those of physics teachers; this was not the case for biology teachers and Earth science teachers. Themes emerging from a qualitative analysis of the interviews included the following: a) In-service teachers have received little formalized training in regard to working with multicultural students; and b) Differences in teacher beliefs and attitudes reported in this study could be the result of diminishing representation of students from multicultural backgrounds in the different sciences, particularly as students move through a traditional progression from biology, to Earth science, to chemistry, to physics.

Educators are increasingly focused on the process over the content. In science especially, teachers want students to understand the nature of science and investigation. The emergence of scientific inquiry and engineering design teaching methods have led to the development of new teaching and evaluation methods that concentrate on steps in a process rather than facts in a topic. Research supports the notion that an explicit focus on the scientific process can lead to student science knowledge gains. In response to new research and standards many teachers have been developing teaching methods that seem to work well in their classrooms, but lack the time and resources to test them in other classroom environments. A high school Physics teacher (Bradford Hill) has developed a unit called Patterns in Nature (PIN) with objectives relating mathematical modeling to the scientific process. Designed for use in his large public school classroom, the unit was taken and used in a charter school with small classes. This study looks at specifically whether or not the PIN unit effectively teaches students how to graph the data they gather and fit an appropriate mathematical pattern, using that model to predict future measurements. Additionally, the study looks at the students' knowledge and views about the nature of science and the process of scientific investigation as it is affected by the PIN unit. Findings show that students are able to identify and apply patterns to data, but have difficulties explaining the meaning of the math. Students' show increases in their knowledge of the process of science, and the majority develop positive views about science in general. A major goal of this study is to place this unit in the cyclical process of Design-Based Research and allow for Pattern in Nature's continuous improvement, development and evaluation. Design-Based Research (DBR) is an approach that can be applied to the implementation and evaluation of classroom materials. This method incorporates the complexities of different contexts and changing treatments into the research methods and analysis. From the use of DBR teachers can understand more about how the designed materials affect the students. Others may be able to use the development and analysis of PIN study as a guide to look at similar aspects of science units developed elsewhere.

This study investigated whether girls achieve better results in Physical Science in single sex environments or in co-educational classes. Thirteen independent South African schools where children were of similar socio-economic background were considered. Grade 12 Matriculation Physical Science examination results for 1999 to 2003 were analysed using Bonferroni (Dunn) t-Tests and Scheffe's Tests. Questionnaires were completed by a small number of students in order to compare their attitudes towards Physical Science and examined qualitatively. There were significant differences found by the administration of the Bonferroni (Dunn) t-Tests and Scheffe's Tests in 2000, 2001 and 2002 to indicate that girls in single sex schools achieved better results in Science than the co-educational schools. However, in 1999 and 2003 there was no significant difference in the results achieved, and so there may be other factors that are more important predictors of achievement than whether the schools are mixed or single sex. / Educational Studies / M.Ed.

The shortage of specialist Physics teachers in senior secondary schools in Swaziland has, for years, been one of the nagging issues for the Ministry of Education and Training (MoET). This led MoET to exploiting the services of non-specialists, thus undermining the quality of learners who graduate from the system. Therefore, the study ascertained the causes of the shortage of specialist Physics teachers in senior secondary schools in Swaziland, how they could be retained and how their number could be increased. A positivist-interpretive quantitative research approach was utilised to obtain reliable and valid results in this study. The quantitative research was a survey consisting of a questionnaire that was completed by Physics teachers in senior secondary schools. The data were analysed using descriptive statistics. The study, based on the findings, concluded with some recommendations that could be used to retain and increase the number of Physics teachers in senior secondary schools. / Curriculum and Instructional Studies / M.
