- Description
- This study emerged in response to the poor performance in Biology at my school. The Ministry of Education Biology (NSSCO) Examiners’ report (2011) for Paper 3 indicates that learners proved to have difficulties in designing experiments, failed to give a distinction between apparatus and the experiment. The 2012 Examiners’ report on transpiration also highlights that learners were not exposed to practical work. Furthermore, the 2012 report notes that teachers need to work on their learners’ drawing and spelling of terms. It is against this backdrop that a qualitative study was conducted at a school in Oshikoto, using a sample of two teachers. The study’s purpose was to investigate how grade 11 Biology teachers mediate learning of the topic on transpiration. Social Constructivism and Pedagogical Content Knowledge formed the framework used to analyse data gathered from document analysis, interviews and observations. The study findings were that teachers use locally available material for demonstration during practical work, elicit prior knowledge, use a chalkboard to summarise content to learners, and use a question and answer method as strategies in mediating learning on transpiration. In addition, the teachers use homework, scaffolding activities, group work, code-switching, feedback on activities, as well as the use of analogies. Despite efforts by participant teachers to mediate learning of transpiration, shortage of equipment for conducting practical work, poor English proficiency among teachers and learners, and little emphasis on graphing by the syllabus proved to be barriers to their efforts. This study thus recommends that in order to improve on teaching transpiration, teachers need to co-plan lessons, conduct practical work, code-switch during lessons, ensure effective assessment, and include lessons on graphing. Furthermore, teachers need continued training on how to teach transpiration.
