Class size and Learners’ Engagement in Physics Practicals in Ordinary Level Secondary Schools of Bukanga North County, Isingiro District

The study investigated the effect of class size on learners’ engagement in physics practicals in ordinary-level secondary schools in Bukanga North County, Isingiro District. The objective of the study was to examine the effect of the number of students on learners’ interaction with teachers during physics practicals. The study used a correlational survey design. The study population included senior three learners, physics teachers, laboratory attendants, school headteachers, the District Education Officer, and the District Inspector of Schools. A sample size of 352 respondents was used. Sampling methods included purposive and random techniques. The data collection methods included self-administered questionnaires, interview guides, and observation checklists. Qualitative data was analysed using thematic, content, and narrative analysis while quantitative data was analysed with SPSS. A significant positive correlation (r = 0.820) suggested that as the number of students decreased, the learners’ interaction with the teacher in ordinary-level physics practicals increased. The research recommends that schools should reduce student numbers in physics practical classes, provide teacher training, implement flexible seating arrangements, ensure proper classroom resources, determine an optimal number of students, and consider classroom layout adjustments to enhance the effectiveness of physics practicals
