Thesis (MEd)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: This research study investigated the use of a practical activities-based approach to Physical Sciences teaching using TRAC equipment to address learner conceptual difficulties in Electricity and Magnetism (E&M). TRAC uses practical activities based on the school curriculum to complement the theory through the utilisation of data logging equipment linked to a computer. The participants in this study were a group of black Grade 11 learners (n=47) from a township school in the province of the Western Cape, South Africa. Their ages range from 16 to 21, with isiXhosa the home language of most of them. A mixed methods approach was utilized to gather the research data. Quantitative data was collected, using pre- and post-testing of learners to determine their conceptual difficulties in E&M, as well as to measure the effect of the practical activities-based approach in addressing learner conceptual difficulties in E&M. Null hypotheses were formulated for the six concepts and t-tests were used to find any statistically significant difference between the pre- and post-test. Qualitative data was obtained from the learner transcripts, as well as from the questionnaires and observation schedules. The results indicated significant improvements in learner understanding of the concepts in five out of the six tests as well as reducing commonly held misconceptions in E&M. It is recommended that careful scaffolding should be done during a practical activity in order for learners to make the connection between the domains of observables and ideas. / AFRIKAANSE OPSOMMING: Hierdie navorsingstudie het die gebruik van ‘n praktiese aktiwiteitsgebaseerde benadering tot Fisiese Wetenskappe onderrig met behulp van TRAC apparaat ondersoek. Die doel was om leerders se konseptuele haakplekke in Elektrisiteit en Magnitisme (E&M) aan te spreek. TRAC maak gebruik van ‘data logging’ apparaat om die teorie deur middel van praktiese aktiwiteite wat op die skoolkurriulum gebaseer is, te komplementeer. Die deelnemers in die studie was ‘n groep swart Graad-11 leerders (n=47) uit ‘n swart woongebied in die Westelike Provinsie, Suid Afrika. Hulle ouderdomme strek van 16 tot 21 met isiXhosa as die huistaal vir die meerderheid van hulle. ‘n Gemengde metode benadering was gebruik om die navorsingsdata te versamel. Kwantitatiewe data was deur ‘n voor- en natoets van die leerders versamel om hulle konseptuele haakplekke in E&M te bepaal. Die effek van die praktiese aktiwiteitsgebaseerde benadering om die leerders se konseptuele haakplekke in E&M aan te spreek was ook gemeet. Nul hipotese was vir die ses konsepte geformuleer en t-toetse was gebruik om statisties-beduidende verskille tussen die voor- en natoets te bepaal. Kwalitatiewe data was van die leerders se oorgeskryfde onderhoude sowel as vraelyste en observasieskedules verkry. Die resultate toon ‘n beduidende verbetering in leerders se begrip van die konsepte in vyf van die ses toetse sowel as ‘n afname in algemene wanbegrippe in E&M. Dit word aanbeveel dat versigtige opbouing gedurende die praktiese aktiwiteit gedoen moet word sodat die leerders ‘n verband tussen die domein van waarneembares en idees kan maak.

The aim of the study was to establish the possible causes of poor Grade 12 results in physical science in South Africa and to apply a total quality management (TQM) approach to suggest a solution. The literature study indicates that resources, preparation or subject knowledge, commitment and support affect the quality of performance. The research was done in one school district (cluster). Following the literature study a questionnaire was distributed to 150 science teachers from 31 schools and the response rate was 73% (113 responses). The questionnaire tested the respondents' perception on the availability of resources and the support received by them, the support given to learners and their level of preparation and subject knowledge. From this, as well as from the biographical information from the questionnaire, certain conclusions were made about the reasons for poor performance of learners in science examinations. It could be concluded from the analysis of the results that limited support to teachers and support to learners are important factors contributing to a poor Grade 12 pass rate. The pass rate also correlates positively with experience levels of teachers. Although 39% of teachers are unqualified or under-qualified, no significant correlation could be found between pass rate and level of qualification. Analysis of the effect of commitment on pass rate was inconclusive. / Thesis (M.B.A.)--North-West University, Potchefstroom Campus, 2011.

The performance of learners in Physical Sciences in South Africa has been very poor for a very long time because of lack of basic understanding of scientific concepts. Given this background, there is the need to conduct an educational research to find pedagogical ways to improve performance in Physical Sciences in the secondary schools. Hence, the proposed study aims to investigate the use of science resource centres and laboratories to improve Physical Sciences education in Mthatha. In the light of the literature review, a list of facts were acquired which were used to develop the questionnaire for the Physical Sciences learners and their teachers. Seven public and private high schools in Mthatha were selected for the study. Stratified simple random sampling was used to select respondents. The study followed a non-experimental quantitative design to collect data. The main instruments used were questionnaire and interview. The various responses were analysed and interpreted with the literature. It was found that, the use of science resource centre and laboratory activities, together with a more learner-centred approach to teaching would significantly improve learner performance in Physical Sciences. The necessary recommendations and suggestions were made. It is hope that these recommendations would be taken up by the appropriate bodies to ensure that the needed benefits are obtained from the science resources, and laboratories. In this way, the science and technological base of the nation as a whole is strengthened for its development. / Science and Technology Education / M. Ed. (Natural Science Education)

Poor Physical Science performance in South African schools is due to ineffective Physical Science teaching. Quality Physical Science teaching stems from quality Physical Science subject advisory services. Traditionally interventions to raise teaching standards were done by inspectors who established if schools functioned according to set rules rather that supporting teaching staff. School inspection was considered a fault finding mission with punitive objectives; hence principals and teachers were negatively disposed to it. The Department of Basic Education since has re-interpreted intervention from checking compliance to support and development of school personnel. This task is allocated to units in district offices in provincial Departments of Education and district staff members’ responsibilities are linked to responsibilities of principals and teachers. The subject advisory unit focuses on curriculum matters in each school subject; thus Physical Science subject advisors support Physical Science teachers with content, pedagogical content knowledge, assessment and Interventions for improved results. This study investigated the role of Physical Science subject advisors in enhancing the quality of Physical Science teaching. Requirements for employment of a subject advisor (qualifications, work experience, interest, attitude and competence), challenges and solutions were explored by a mixed method study. A Physical Science provincial DCES, Physical Science subject advisors, principals, Physical Science teachers in four districts and four PLC support groups were purposefully sampled to explore perceptions of the subject advisor’s role in improving Physical Science teaching. Quantitative data collected by document analysis and questionnaires and qualitative data collected by individual and focus group interviews were analysed. Findings showed that the Physical Science subject advisors possessed minimum qualifications and experience; however, the school subject (Physics and Chemistry combined) does not match the specialization in tertiary institutions (divided into Physics and Chemistry). Thus, some subject advisors may major in one of two parts. Further, certain school content is not included in the university syllabus. This may limit advisors’ content knowledge, the core of content support in Physical Science. This influences support offered to Physical Science teachers and requires advisors’ professional development which is not currently offered by the Department of Basic Education. Recommendations based on the findings include immediate and long term solutions to improve effective subject advisory. / Curriculum and Instructional Studies / D. Ed. (Curriculum Studies)

The integration of knowledge and skills across subjects and terrains of practice is crucial for achieving applied competence as defined in the National Qualifications Framework (NQF) (Department of Education 2003:3).). Physical science underperformance has plagued out Further Education Training (FET) schools sector for some time and therefore this study which is directed at the possible causes of poor performance and to device strategies that could assist physical science teachers to teach more effectively addresses a crucial gap in the performance of the country’s education provision. Emanating from the above, this study focused on the impact of National Curriculum Statement principle in the teaching of physical science in Grades 10 to 12 around Sekhukhune district. The study looked at integration as a principle endorsed in the National Curriculum Statement and how this is implemented by teachers in the teaching of physical science in grades 10-12.A literature study on the impact of National Curriculum Statement principle in the teaching of physical science was undertaken. A qualitative approach was used to obtain data from Grades 10-12 teacher in FET around Sekhukhune district. Data were collected in the form of participant observation, semi-structured and focus group interviews. The results indicate that teaches had no clear idea of integrating the relevant concepts in the subjects they were teaching (physical science). It was also found that teachers did not receive adequate in-service training specifically targeting the principle of integration. The study recommends the professional development of physical science teachers. The study indicated that the continuum model of integration is suitable for the implementation of concepts integration. It is believed that if the continuum model of integration could be used and followed by teacher as a guiding principle in the integration process, the challenges experienced by teachers in this regard will be minimized. / Science and Technology Education / M.

Learners’ Physical Science performance in South Africa has been under discussion for several years, the challenge being that it has been exacerbated by continuous changes in the curriculum. Systems that have been put in place have yielded insufficient satisfactory solutions to both underperformance in the subject and sustainable good performance. Although interventions by curriculum policymakers have been ineffective, the issue at hand remains that teachers need to implement good teaching practices in order to ensure that all learners receive quality education. Physical Science teachers are custodians of a subject that may address scarce skills in the education system, so the quality of teaching must be optimised. Teachers need to implement intervention processes put in place by other stakeholders to reduce the negative perceptions that most people have about Physical Science. This study investigates how various factors related to the quality of teachers may affect the performance of Grade 12 learners in this subject. Since past studies have presented a broad spectrum of these factors, this study has categorised them as those directly related to teaching and those indirectly related to teaching. As a basis for data collection the researcher first established the overall status of the Physical Science teachers and investigated how the factors identified affect teaching. A mixed method approach was followed, and given the breadth of the study, available raw data was collected through questionnaires, interviews and observations. Data collected on factors indirectly related to teaching showed that these factors affect factors directly related to teaching and both of them affect the performance of the teacher, and consequently those of learners. These findings revealed that the performance of Physical Science cannot be based on one factor only, but on a combination of factors that are interrelated and should be integrated for effective teaching practices. Recommendations have been made to the National and Provincial Department of Education, District offices, school management teams and Physical Science teachers to reinforce other strategies that have been in place in order to improve or sustain good performance of the subject and to close gaps that have not been identified as possible intervention strategies. They include upgrading qualifications with the current content and methodologies to match the changing curriculum, restructuring workshops so that they are informed by the teacher’s needs, stabilising the curriculum to avoid many changes in short periods of time, retraining of teachers, relevant appointment of Heads of Departments (HoDs) into subject management positions, utilisation of support groups by teachers, proper management of the subject, proper screening of Physical Science learners and provision of teaching and learning resources. / Science and Technology Education / M.

The purpose of the research was to investigate the effectiveness of using multimedia as a means of teaching physical science to learners. The underlying theoretical assumption was that a multimedia presentation would help to reduce the cognitive load experienced by learners when they learn physical science content, compared to a traditional mode of presentation, and that this reduction may have a positive effect on the ease with which they master the content. Physical science learners in Grade 11 viewed a presentation consisting of multimedia screens and screens depicting the learning content in a traditional layout – in order to compare the level of knowledge gained as well as the cognitive load experienced for the multimedia and traditional instructions. Pre- and post-test questionnaires were used to determine the knowledge gained, while cognitive load was measured using a dual-task methodology. A multivariate analysis of variance was used to analyse the data. The results did not reveal a statistically significant increase in knowledge gained via the multimedia approach when compared to the traditional mode of instruction, but when focussing the analysis on learners with a lower-knowledge base in physical science though, statistically significant results were found. However, no significant results were found to support the hypothesis that multimedia would help to reduce learners’ cognitive load. It was concluded that the multimedia design principles are more effective in increasing knowledge for physical science learners of low-knowledge than traditional instructional designs. / M. Sc.

The two-part Views on Chemistry Practicals (VOCP) instrument for measuring the views of grade 10 to 12 Physical Science students about the benefits and problems of Chemistry practicals was empirically developed and trialed using six schools in Gauteng. The summary part of the resultant VOCP instrument comprises 24 Likert items and the explanatory part comprises 24 multiple-choice items with 163 options, thus creating a unique current record of a wide range of students' views of chemistry practicals and providing teachers with a tool for improving chemistry practicals. The trial of the instrument with 230 students from three schools indicated that the summary part of the instrument is reliable (Cronbach alpha coefficient) and that a shortened explanatory part of the instrument is reliable (Chi squared values for 17 items with 98 options). The validity of the VOCP instrument was established through the empirical development of the instrument using triangulation of data. / Educational Studies / M.Ed. (Natural Science Education)
