Contemporary society has witnessed a growing trend of technological innovations in the educational landscape. The phenomenon has been widely integrated into the education system of Nigeria. Perhaps, researchers have deployed different computer technologies to enhance students performance in varying subjects. The present study aims to determine whether computer-assisted instructional methods would affect students engagement in physics in secondary school. A total of one hundred and eighty-seven secondary school students were drawn from eight public secondary schools in Ankpa and Lokoja in Kogi state as the studys participants. The study adopted aquasi-experimental pre-test, post-test study design. The result revealed a significant difference in students engagement in physics between the students taught with the computer-assisted instructional method and those taught with the conventional way at MD = 5.08, t (185) = 7.328, p = .000. Thus, the study concludes that a computer-assisted instructional method is an indispensable tool that could influence students engagement in physics, especially among secondary school students. The practical implications and recommendations are discussed.
