The Effect of Using the 5E Instructional Model on Students’ Performance in and Motivation to Learn Sine Rule and its Applications

Abstract

This study investigated the effect of using the 5E instructional model on Senior High School student’s mathematical achievement in the application of the sine rule. A quasi-experimental, non-equivalent control group, pre- post-test research design was used in the study. Convenience sampling technique was used to select two intact class groups’ representing a control and an experimental group. Trigonometry tests (pre-test & post-test) and questionnaires which generated quantitative and qualitative data were used to collect data. Descriptive, inferential and thematic analytical methods were used to analyze the data generated.  The results showed that there was a significant difference between the mean performances of the experimental and control group. The average mean performances of each of the two groups showed that the experimental group performed better than the control group. Again, the results showed that the use of the 5E instructional model was fun, practical, interactive and interesting hence motivates students to learn trigonometry, specifically sine rule and it’s application. The study recommended that Mathematics teachers should adapt the 5E instructional model in teaching trigonometric concepts to promote retention and transfer of knowledge.
