    The impact of Mastep on the use of practical work in Namibian science classes
    (University of Namibia and University of York, 2006) Kandjeo-Marenga, Hedwig U.; Kapenda, Hileni M.; Lubben, Fred; Campbell, Bob; !Gaoseb, Noah; Kasanda, Choshi D.
    This 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 system

    Proceedings of the 14th Annual SAARMSTE Conference. University of Pretoria , 2006

    The MASTEP professional development intervention programme set out to improve the teaching of science and mathemancs in senior secondary schools Namibia. This paper demonstrates that teachen who participated in MASTEP (science, i.e. biology and physical science) changed their practice in ways that embraced the use of everyday contexts and reflected a more learner centred approach to science education The nature of the change and the stimulus for change are discuss

    Research in Science & Technological Education
    (Carfax Publishing, 2002) Kapenda, Hileni M.; Kandjeo-Marenga, Hedwig U.; Kasanda, Choshi D.; Fred, Lubben
    This paper presents a study into science practical work conducted in Namibian classrooms. Lesson plans, task sheets, student work, lesson transcripts and observation notes were used to identify intended learning Outcomes. In addition, aspects of task design (inductive-deductive; open-closed; nature of student involvement) and the context of the practical task (duration; interaction patterns; types of task information and apparatus; nature of the student records were explored. A profile form was used and its usefulness evaluated for the analysis of 12 practical Tasks. The findings showed an emphasis on conceptual as opposed to procedural objectives, and a frequent change from an inductive to a deductive approach during the execution of the tasks pupil practical activity was rarefy Consolidated as a laboratory report but functioned as an enjoyable introduction to a set of general questions on the Content covered in the practical. Suggestions are made for the modification of the profile form, and for in-service.

    The role of practical work in science teaching in Namibia
    (SAARMSTE, 2001) Kapenda, Hileni M.; Kandjeo-Marenga, Hedwig U.; !Gaoseb, Noah; Kasanda, Choshi D.
    This paper presents a study into science practical work conducted in Namibian classrooms. Lesson plans, task sheets and student work are used to identify the intended learning outcomes. In addition, aspects of task design (inductive-deductive; open-closed,ยท nature of student involvement) and the context of the practical task (duration; interaction patterns; types of task information and apparatus; nature of the student record) are explored. Millar's Profile Form is used to analyse twelve practical tasks. Findings show an emphasis on conceptual instead of procedural objectives, and a frequent change from an inductive to a deductive approach during the execution of the tasks. The practical activity is rarely consolidated in a laboratmy report but functions as an enjoyable introduction to a set of unrelated consolidation questions. Suggestions are made for the modification of the analysis scheme, and for in-service activities to support teachers to use practical work more effectively.
