The influence of foundation physics on the performance of students in Physics I at several South African universities

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 EducationD. Phil. (Mathematics, Science and Technology Education

The story of a physiclal science curriculum: transformation or transmutation?

This is an Accepted Manuscript of an article published by Taylor & Francis in African Journal of Research in Mathematics, Science and Technology Education on 20 Aug 2013, available online: http://www.tandfonline.com/10.1080/10288457.2012.10740745.Recently Curriculum and Assessment Policy Statements (CAPS) were introduced in South Africa in response to confusion precipitated by previous curriculum documents. The purpose of this paper is to explore that confusion in the subject 'Physical Sciences' and consider the nature of the transformation from the previous curriculum by looking at curriculum documents and examination papers. We present a two phase curriculum change model which suggests that congruency between curriculum documents and examinations is critical for effective curriculum change. We analyse the pre-CAPS curriculum, the National Curriculum Statement (NCS), on its own terms by using the stated outcomes as our reference point. Our analysis reveals that the weighting and conceptualization of the outcomes shifted through successive documents, which undermined congruency between the documents and meant that content-oriented science masqueraded as inquiry-oriented science. This led to a retreat from the original vision of weighting skills and relevance equally with content. The examinations took this retreat a step further. Evidence of the retreat is that the nature of the questions asked in the 2008 examinations on the NCS was similar to that of the 2007 examinations on the previous curriculum which had not changed since apartheid. However, in the NCS examinations there was a small shift towards contextualisation and inquiry oriented science. The retreat means the vision of transformation which was the rationale for the NCS curriculum was eroded – instead of transformation, there was transmutation back to the old apartheid curriculum. The Physical Sciences CAPS cements the retreat and creates new confusion by changing the syllabus again without signposting the change

Do gender differentials play any role in university physics students’ performance?

Against international literature that indicates that gender differences exist in the performance in introductory physics level students, this paper has examined the prospects of gender based differences in students’ performance in introductory physics at the university level in South Africa. The study was conducted at four South African universities using a sample of 194 students. A third (68) of the participants in this research were female students. Student performance was measured through two instruments, namely 1) The Force and Motion Conceptual Evaluation (FMCE) tests adapted from Thornton and Sokoloff (1998) and 2) the student’s introductory physics mechanics marks. Both FMCE and mechanics courses lay the foundation for other physics courses. Student performances on the two instruments were analysed. The students’ outcomes on these tests suggest that in the South African context, gender differentials do not necessarily predict performance in physics. In conclusion, this paper discusses other factors which in the context of South Africa need attention as possible barriers to general outcomes in physic
