Utilisation of Produced Engine Mock-Ups for Students' Excellent Performance

This study determined the effects of the treatment instrument on students' performance in Auto Mechanical Work (AMW); and the effect of gender on students' achievement in AMW. The quasi-experimental research design with a pretest-post-test non-equivalent control study was adopted for this study. Two Teachers and thirty-five students at two schools in Lagos State participated in this study. The treatment instrument and students' achievement test were used as research instruments for this study. The instruments were validated and pilot-tested with reliability coefficient of 0.84. The data collected were analysed quantitatively. Findings revealed that the experimental group students outperformed the control group students, and the experimental female group students outperformed the experimental male group students in the test. The study concluded that locally produced instructional materials facilitate students' academic excellence and eradicate learning difficulties. The study recommended that students' academic performance should be sustained through regular availability of instructional materials.
