This study was aimed to investigate the effect of simulated analogical reasoning blended with group discussion method on secondary school students' physics achievement. A total of 120 grade 10th students from three different high schools found in Debre Tabor Town, Ethiopia was selected and assigned as three experimental groups randomly to be treated through simulated analogical reasoning blended with group discussion method, concrete analogical reasoning method blended with group discussion method and alone in the learning of contents of electricity and magnetism. A quasi-experimental design was used. Electricity and magnetism performance test was employed to collect data. One-way ANOVA result indicated that students who used simulated analogical reasoning blended with group discussion method achieved a significant larger mean score in their performance test than other groups. To this end, this teaching method is more effective to enhance students' achievement than other model of analogy-based instructions.
