Exploring the efficacy of practical work on learners’ academic achievements in biology at senior secondary level in Namibia

This study examines the impact of practical laboratory work on the academic performance of senior secondary biology learners in the Khomas Region Namibia. Employing a quantitative research approach, data was collected from four purposively selected schools. Data were collected through document analysis of the four schools of with two schools were fully furnished with science laboratory and the other two lacked science laboratory. Descriptive statistics were employed to analyze quantitative data. The findings indicate a notable influence of laboratory exposure on academic performance of learners in understanding science concepts, with learners who have access to laboratory facilities demonstrating higher levels of achievement. However, it was also observed that even learners without laboratory access strive to excel by diligently grasping theoretical concepts. Recommendations drawn from this study include advocating for the establishment of laboratories in schools lacking such facilities, as well as encouraging collaboration between schools to facilitate access to laboratory resources. This study underscores the importance of practical work in biology and calls for concerted efforts to ensure equitable access to laboratory resources for all learners.
