Using a model (tlms) to assist female junior high school pupils demonstrate rectilinear propagation of light in Bongo District

Abstract

The study examined how to demonstrate Rectilinear Propagation of Light using a Model (TLMs) with Collaborative teaching techniques to assist female Junior High School pupils improve their academic performance in Rectilinear Propagation of Light. The study used a descriptive survey that employed the quasi-experimental research and non-randomised Control and Experimental groups’ pre-test – post-test design. The total population for the study was 227. The sample size was 74 students. The selection procedure was nonrandomised. Two Intact classrooms were used for the study. The Control group (Group A) and the Experimental group (Group B) consisted of an equal number of 37 students as this arrangement was the prevailing situation in the two intact classes at the time the study was conducted. Collaborative Approaches were used as treatment for the Group B; whiles the Traditional Method was used for the Group A. The instruments used in the study were Pre-tests, Post-tests and questionnaire. The reliability coefficients were found to be 0.736 and 0.751 for the pre-test and post-test respectively. Data were analysed using tables and bar charts. The results of the study revealed that the use of the Model resulted in significantly higher students’ achievement in Rectilinear Propagation of Light than the Traditional Method.
