Blended Learning Approach for Students with Special Educational Needs: A Systematic Review

Abstract

This study aimed to determine the effectiveness of Three step interview as a strategy on the performance in science of grade 8 students. Specifically this study aims to find out the significant difference on the pretest scores in science of the students when grouped to Three step interview as a strategy and lecture method; it finds out the significant difference on the posttest scores in science of the students when taught using Three step interview as a strategy and lecture method and; it finds out the significant difference on the pretest and posttest scores in science of the students when taught using Three step interview as a strategy and lecture method. The study used the true experimental design. T-test, percentage and paired t-test were used to analyse the data. The results revealed that there was no significant difference on the prestest scores in science of the students when grouped to Three step interview as a strategy and lecture method since the t-value which is-1.32 corresponds to the p-value of 0.191 and is greater than p ≤ 0.05 level of significance. The analysis also revealed that there was a significant difference on the posttest scores in science when students were taught using Three step interview as a strategy and lecture method since the t-value which is 4.61 corresponds to the p-value of 2.26X10-5 is lesser than p ≤ 0.05 level of significance. The paired t-test results revealed that for the Three step interview group, there was a significant difference on the pretest and posttest scores in science of grade 8 students since the t-value which is-13.76 corresponds to the p-value of 3.02X10-14 is lesser than p ≤ 0.05 level of significance. For the lecture method group, there was significant difference on the pretest and posttest scores in science of grade 8 students since the t-value which is-12.04 corresponds to the p-value of 8.33X10-13 is lesser than p ≤ 0.05 level of significance. The use of the Three step interview as a strategy in teaching science can greatly improve students' performance.
