The Interplay of Age and Web-Based Instruction: Effects on Commerce Students Achievement in Senior Secondary School

This study examines the influence of age on the impact of a web-based instructional application (WBIA) on the academic achievement of Lagos State senior secondary school students in commerce. Two research questions and one hypothesis were formulated to guide this study. This research adopted a quasi-experimental design. The study focuses on senior secondary school II Commerce students in Lagos State, Nigeria. A convenience sampling technique was employed to select the representative sample schools. One hundred and eight commerce students, including males and females, were selected and examined using intact classes. A Web-Based Instructional Application was developed to teach five different topics in commerce. The Commerce Achievement Test (TCAT) was used to collect data for this study and was validated. The reliability obtained was r = 0.83 (p < 0.01). The findings revealed that the impact of age on achievement did not attain statistical significance [F (1, 105) = 0.05; p > .05]. It was therefore recommended that educational institutions should adopt Web-Based Instructional Applications (WBIA) as a standard tool for teaching commerce and other subjects. The study highlights its effectiveness across different age groups, demonstrating that it is a versatile tool for enhancing academic achievement.
