Effectiveness of using websites in the teaching of transport system in Humans: A case study of a rural high school in Omusati region, Namibia
Several countries recognised the importance of websites usage in education for teaching and learning. In Namibia, the use of websites in teaching remains limited. The purpose of this study was to explore the effectiveness of usage of websites to teach the topic of transport system in humans in Biology as a school subject at a selected rural high school in Omusati Region in Namibia. The study adopted a qualitative approach using single case study. A sample size of three Biology teachers was used for the study. A purposive sampling technique was adopted to compose the sample. Three research questions were answered. Data was collected over a one-week period using open-ended questionnaire, observation schedule and photographs and analysed using thematic analysis. Major findings were that the usage of websites in teaching transport system in humans in the selected rural high school has a great effectiveness for both teachers and leaners. Findings also indicate that Biology teachers used websites in several ways to teach the topic transport system in humans. Moreover, findings also indicate that Biology teachers in the selected rural high school faced a lot of challenges regarding the usage of websites at the initial stage of the study, which were addressed and resolved. Some of the challenges identified were inadequate technical and financial support towards the usage of websites at school and poor websites skills in both teacher and learners. Based on the above, it is recommended that each rural high school invest in Wi-Fi with stronger signals, teachers should post past examinations on websites and there is a need for a study to determine the extent to which rural high schools customise and implement websites usage in Biology for purposes of achieving effective website usage in teaching.
