Abstract
This study examined an experimental investigation of guided-discovery teaching method and instructional materials utilization on Economics performance of secondary school students in Oyo State, Nigeria. Pretest-posttest, control group quasi-experimental design with a 2×2 factorial matrix was used in the study. Multi-stage sampling technique was used in sampling 78 participants from 4 local government areas in the state. The respondents were measured with Economics Performance Test of 21 items with 0.89 internal consistency obtained from test-retest method of reliability. Data obtained was analyzed using t-test statistical analysis. Two (2) research questions and two null hypotheses were formulated and tested at 0.05 level of significance. The result of the investigations revealed that there was significant difference in the performance of students taught with guided-discovery teaching method and those taught with normal conventional methods in the control group (t(76)= 43.67; p<0.05) and there was significant difference in the Economics performance of secondary school students taught with instructional materials and those without instructional materials (t(76)= 33.41; p<0.05). In view of these findings, the study recommended that teachers and other stakeholders should be trained on how to improve on the instructional materials utilisation and guided-discovery teaching method and that curriculum planner should include effective teaching strategies/methods into teacher training institutions/programmes. This will help in sharpening the skills of teachers towards instructional content delivery so as to enhance the students’ academic performance.
