Abstract: This study was designed to determine the effect of task instruction sheets on foundry students’ retention in polytechnics of North Central, Nigeria. This study adopted a quasi-experimental research design. Specifically, the pre-test post-test non-equivalent control group design which involved groups of students in their intact classes assigned to experimental and control group. The sample size for this study was 271 and comprised 236 males and 35 female students in all the intact classes in the participating schools. The experimental group had a population of 138 subjects made up of 116 male and 22 female students while control group had a population of 133 subjects comprising 120 male and 13 female students. Two research questions were formulated and three null hypotheses tested at 0.05 level of significance. The instruments used for data collection for this study was Metal Casting Technology Retention Test (MCTRT). To ensure content validity of the MCTRT. The MCTRT was trial-tested to determine the suitability and reliability coefficient which was found to be 0.87 for MCTRT using Kuder-Richardson formular 20 (KR-20) approach. To collect data, students in both groups were subjected to pre-test before experiment, posttest after the experiment as well as administering of MCTRT. Mean was used to answer the research questions while Analysis of Covariance (ANCOVA) was used to test the null hypotheses that guided the study at .05 level of significant. The study found out that there was a positive effect of gender on students’ retention in sand casting favoring boys. The study also found out that there was significant interaction effects of treatments and gender on Foundry students’ retention in sand casting. It was therefore, recommended among others that Foundry lecturers/ teachers should adopt the use of task instruction sheet in teaching sand casting, The National Board for Technical Education (NBTE) should support instructional effectiveness by training teachers on the use of task instruction sheet as well as in design of task instruction sheet lesson plans for use in polytechnics.
