This is an experimental study that examined the comparative effects of Tripolar Interactionist teaching strategy on the academic performance of Junior Secondary School III students of Adeyemi Demonstration secondary School Ondo in social studies. The instrument used for the study includes scheme of work, lesson notes prepared by the researcher and the result of the administered tests on the basis of the research conducted. Two groups of 25 students each were taught the same content and within six weeks using the conventional method and Tripolar Teaching Strategy comprising of enquiry, questioning and discussion methods. The findings showed that the students taught using Tri-polar Teaching strategy performed better at the higher and middle lowest level than students taught using conventional method. Based on the finding it was recommended that the configured teaching strategy tagged "Tri-polar" should be adopted for teaching and learning in Nigerian

This study aims to determine the effectiveness of the Culturo-Techno-Contextual Ap- proach (CTCA) on students’ achievement and critical thinking skills in Computer Studies. The study was conducted in two phases. Phase one was a survey of difficult concepts in computer science/studies. While phase two explored the potency of the Culturo-Techno-Contextual Approach (CTCA) in breaking the barriers to meaningful learning of refractive indices. Results obtained from the survey in the first phase revealed 19 topics as a difficult topic among African secondary school students in computer studies. The second phase was guided by two research questions with two public junior secondary (JS) in Lagos State (Nigeria). About 38% of the respondents were males while about 62% were females. A critical thinking skills task (CTST), and an interview guide were used to collect data for the study. The data gathered was subjected to multivariate analysis of covariate (MANCOVA), and the results revealed a statistically significant difference in the methods used, multivariate F (Pillai’s Trace) was significant [F=17.67; p<.05], univariate ANOVA on achievement [F (2, 208) = 20.67; p<0.05]; and critical thinking skills [F (2, 208) = 15.14; p<0.05]. Within the scope of the study, it was tentatively recommended that CTCA should be adopted by computer studies teachers in the teaching of computer science/studies in secondary schools.
