This study outlines the strategies that were employed during the training of Grade 11 Physical Sciences teachers in the use and development of an Electronic Performance Support System (EPSS). The EPSS process involves extended individualised support for teachers through face-to-face training. A purposive sample was utilised and 22 Grade 11 Physical Sciences teachers participated in the study. Teachers’ skills and knowledge before and after the EPSS training process were measured on three measures of satisfaction (course material, the EPSS training process and the trainer’s competencies) and three measures regarding the EPSS (using an EPSS, creating a flowchart and designing an EPSS). A customer satisfaction index questionnaire and retrospective opinionnaire were used to collect data from the participants. Microsoft Excel was used to analyse data collected using the customer satisfaction index questionnaire. Furthermore a Statistical Package for the Social Sciences (SPSS) program was used to analyse data collected using a retrospective opinionnaire. Significant effects were found on all six measures when comparing the skills of teachers before and after attending the EPSS training programme. The results reveal that teachers who participated in the research are satisfied with the use, design and development of an EPSS in education. / Dissertation (MEd)--University of Pretoria, 2013. / gm2014 / Science, Mathematics and Technology Education / unrestricted
