The Effectiveness of Advance Organizer Model on Students’ Academic Achievement in Learning, Work and Energy at Adwa College of Teachers’ Education

Abstract

The purpose of this study was to investigate the effectiveness of the advance organizer model (AOM) on students’ academic achievement in learning work and energy. The design of the study was quasi-experimental pretest–post-test nonequivalent control groups. The total population of the study was 139 first year students of three sections in Adwa College of Teacher Education in Tigray Region, Ethiopia. Two sections with equivalent means on the pretest were taken to participate in the study purposely and one section was assigned as the experimental group and the other section was assigned as the control group randomly. The experimental group was taught using the lesson plan based on the AOM, and the control group was taught using the lesson plan based on the conventional teaching method. Pretest and post-test were administered before and after the treatment, respectively. Independent sample t-test was used to analyze the data at the probability level of 0.05. The findings of the study showed that the AOM is more effective than the conventional teaching method with effect size of 0.49. This model is also effective to teach male and female students and achieve objectives namely understanding and application. However, both methods are equally important to teach work and energy under the objective knowledge level.
