The Impact of Mastep on The Use of Practical Work in Namibian Science Classes. Zimbabwe Journal of Educational Research 18(1):123-126.http://hdl.handle.net/11070/738This article presents an investigation into the changes in the Teaching practices of practical work in senior science classes in Namibia. The teachers in this study are involved in training Programme, the Mathematics and Science Teacher Extension Programme (MASTEP). Pre- and post-intervention data were Collected from eight Biology teachers and four Physical Science teachers Lesson plans, worksheets and other documentation were Used to characterise practical activities using m1 established Taxonomy classroom interactions were audio-taped and Transcribed verbatim the findings i11dicate an increased focus on Practical activities aimed more at qualitative rather than Quantitative understanding of science concepts. In addition, the Post-MASTEP teachers favoured small group work and demonstrations. The changes in teaching practices arc attributed To the improved PCK that has enabled teachers to align their Practice with the assessment systemenMathematics and Science Teacher Extension ProgrammeImpact of mastepPractical workNamibian scienceSenior science classesArticle
