Abstract: This study investigated the effect of self-learning multimedia packages on students' academic performance in internal combustion engines in tertiary institutions in Rivers State. Specifically, it examined the impact on students' performance when taught types of internal combustion engines and their working principles in automobile technology education programmes in tertiary institutions in Rivers State. A quasi-experimental design was guided the study, with two research questions and hypotheses tested at a .05 significance level. The study population consisted of 162 Year I-IV automobile technology students in three tertiary institutions in Rivers State, with a sample of 71 Year III students. A teacher-made test was used for data collection, validated by two lecturers in the department of Industrial Technology Education (automobile technology option), Ignatius Ajuru University of Education, Port Harcourt, and reliability established through test-retest method. The data achieved were analyzed with Pearson Product Moment Correlation (PPMC), and the coefficient achieved was .84. Analysis of Covariance (ANCOVA) was used to test hypotheses. Findings showed the experimental group (taught with self-learning multimedia packages) performed better than the control group (taught with whiteboard). The study recommends training lecturers to develop and use self-learning multimedia packages alongside conventional teaching methods.
