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

Abstract

The study examined effect of Predict-Observe-Explain on secondary
school Physics students’ attitude in Simple Harmonic Motion in Ogun
State. One hypothesis was formulated and tested at 0.05 levels of
significance. The study adopted pre-test, post-test, control group, quasi-
experimental design. A total of 166 SS2 Physics students in two senior
secondary intact classes in Ogun State were selected through multi-stage
sampling technique, participated in the study. One school was exposed
to each of the Predict-Observe-explain and conventional method for 8
weeks. Physics Attitude Scale (PAS) with 20 items on a four-point Likert
type scale (r=0.73) was used for data collection. Data were analysed
with descriptive and inferential statistics. There was a significant main
effect of Predict-Observe-Explain strategy on students’ attitude towards
Physics (F(1,128)=6.349, p<0.05, ?2=0.047).
The study concluded that Predict-Observe-Explain is more
effective instructional strategy than conventional method of teaching in

enhancing students’ attitude towards Physics because every student
participated in one activity or the other which enhanced conceptual
understanding, creativity and critical thinking. Consequently, it was
recommended that this strategy should be constantly used, while
workshop and seminar should be organized for the teachers for effective
use of the strategy.
