Laboratory efficiency of physics students in mechanics and optics in Lassia Tuolu Senior High Schools

Abstract

This study investigated laboratory efficiency of SHS 3 Physics students in mechanics and optics at Lassia Tuolu Senior High School in the Wa West District. It used census sampling technique to select 54 SHS 3 students. A descriptive survey design was employed. Data were collected through practical performance test and questionnaire. The data were analysed using frequencies, percentages, means, standard deviation and t-test statistics. The findings revealed that students demonstrated an average level of proficiency across all assessed laboratory skills, with particularly strong performance in performing tasks. Additionally, no significant gender differences were observed in laboratory efficiency. Moreover, the study revealed that laboratory efficiency among senior high school Physics students in mechanics and optics was generally well supported by adequate resources, positive learning environments, effective teacher guidance, and favorable student attitudes, although time constraints, irregular practical sessions, and varying levels of student confidence moderately limited its full effectiveness. Based on these findings, it is recommended that Lassia Tuolu Senior High School science teachers provide students with increased opportunities to engage in hands-on, authentic laboratory activities to further enhance their practical skills and scientific reasoning. Lassia Tuolu Senior High School should also provide regular and structured laboratory activities that encourage all students, regardless of gender, to actively participate in experimental work
