This study determined the efficacies of cognitive conflict and 5E instructional models on students' conceptual change achievement and self-efficacy in particulate nature of matter concepts in physics. In this study, non-equivalent groups quasi-experimental design was used. A sample of 195 senior secondary school year 1 students (SSI) with an…

Graphic organizers (GOs) are fast becoming acceptable standard instructional tools across subjects in the education arena globally. However, this visual representation of information is yet to be recognized and integrated into the teaching methods in Nigerian schools. This study, therefore, presents a research-based investigation of the usefulness…

The purpose of this study was to investigate the efficacy of cognitive-conflict-based physics instruction over the traditionally designed physics instruction on students' conceptual change in heat and temperature. The subjects were 249 senior secondary II students from 2 schools purposively sampled from 12 secondary schools. The 2 schools sampled…

The aim of the study was to investigate the influence of gender stereotype as a predictor of secondary school students' self-concept and academic achievement. The study was guided by four purposes, four research questions, and four hypotheses. The study adopted ex post facto design. The research sample was drawn from eight government/public senior…

This study investigated the effects of three strategies (i.e., guided discovery, think-pair-share, and lecture) on senior secondary school students' achievement in chemistry. A pretest, posttest, control group quasi-experimental design with a 3 × 3 × 2 factorial matrix was adopted for the study. Treatment was at three levels (guided discovery,…
