Impact of Advance-Organizer on Academic and Performance in Recycling Solid-Waste-Concept Among Senior Secondary Chemistry Students, Zaria, Kaduna State, Nigeria

This study investigated the Impact of Advance Organizers on Academic Performance in Recycling Solid Waste Concepts among Senior Secondary Chemistry Students in Zaria, Kaduna State, Nigeria. A total of 75 students selected from two Secondary Schools in Zaria Metropolis were used as the study samples from a population of 1,018 students from ten (10) secondary schools. The two schools selected were found to be academically equivalent. One of the schools served as the control group (N=35) and the other served as the experimental group (N=40) which was exposed to Lecture Enriched with Advance-Organizers while the control group was exposed to the lecture method alone for a period of five weeks. Pretest, posttest, post-posttest quasi-experimental and control group design was adapted. Research Instruments was developed by the researcher and validated. Recycling Concept Performance Test (RCPT) with a reliability coefficient of 0.86. Two research questions and hypotheses were formulated. To test the level of significant differences, the research questions were answered using a descriptive statistics that is mean and standard deviation, while the null hypotheses were analyzed using a t-test at p ≤ 0.05 significant level. The major findings from the study Include: students taught Recycling Solid-waste Concept of Chemistry using lecture enriched with Advance-Organizer recorded were significantly better in their academic performance as compared to those taught using lecture method alone: and that the use of lecture enriched with the advanced organizer is gender-friendly. Recommendations were made from the findings of the study such as secondary school teachers should be trained and retrained to use lectures Enriched with the Advance Organizer in order to enhance and boost students’ learning and academic performance in chemistry concepts.
