Effect of Predict-Observe-Explain Strategy on Secondary School Physics Students’ Attitude in Simple Harmonic Motion in Ogun State

The study examined effect of Predict-Observe-Explain on secondaryschool Physics students’ attitude in Simple Harmonic Motion in OgunState. One hypothesis was formulated and tested at 0.05 levels ofsignificance. The study adopted pre-test, post-test, control group, quasi-experimental design. A total of 166 SS2 Physics students in two seniorsecondary intact classes in Ogun State were selected through multi-stagesampling technique, participated in the study. One school was exposedto each of the Predict-Observe-explain and conventional method for 8weeks. Physics Attitude Scale (PAS) with 20 items on a four-point Likerttype scale (r=0.73) was used for data collection. Data were analysedwith descriptive and inferential statistics. There was a significant maineffect of Predict-Observe-Explain strategy on students’ attitude towardsPhysics (F(1,128)=6.349, p<0.05, ?2=0.047).The study concluded that Predict-Observe-Explain is moreeffective instructional strategy than conventional method of teaching in
enhancing students’ attitude towards Physics because every studentparticipated in one activity or the other which enhanced conceptualunderstanding, creativity and critical thinking. Consequently, it wasrecommended that this strategy should be constantly used, whileworkshop and seminar should be organized for the teachers for effectiveuse of the strategy.
