Abstract:
The study compared the effects of LMAO and LM on the achievement of Physics students in DNSD. This study utilized a quasi-experimental 2x2 factorial, pre- and post-test planned variation design. Six thousand seven hundred twenty-five SS II Physics students from Public Secondary Schools in DNSD served as the study's population. Stratified random sampling was utilized to sample 222 SS II students. Physics Achievement Test (PAT) was used to collect data. PAT reliability of 0.88, was established using Kuder-Richardson formula 21. A pretreatment test using PAT was conducted, followed by a posttreatment test. Data acquired were analysed utilizing mean, standard deviation, t-test, and Analysis of Covariance(ANCOVA). The results showed that: there was a significant difference between the mean achievement scores of students taught Physics using LMAO and LM, favouring LMAO. It was concluded that LMAO improves students' achievement in Physics more than LM alone. Thus, it was recommended that Physics teachers should combine the LM with advanced organizers (AO) since LM cannot be totally eliminated.
