EFFECTS OF PROBLEM SOLVING METHOD WITH POWER POINT ON ACHIEVEMENT OF SECONDARY SCHOOL PHYSICS STUDENTS IN REFRACTION OF LIGHT WAVES

Abstract

This study was designed to determine the effect of problem solving method with PowerPoint on SS II physics students’ academic achievement in refraction of light waves in Ilorin Kwara State. Two Research questions were raised and two Null hypotheses were tested. The study adopted a pre-test and posttest control and experimental group design. The representatives sample size for the study comprises of one hundred and twelve (112) Physics students selected using purposive sampling techniques from three (3) senior secondary schools in Ilorin, Kwara State. The Researcher taught the experimental group Refraction of light waves using problem solving method with power point, while the control group was exposed to problem solving method using traditional approach.  The instrument for data collection was 50-items multiple-choice tagged Achievement Test on Refraction of Light Waves (ATRLW) reflecting the content in the lesson note. A reliability coefficient of 0.785 was obtained using Pearson’s moment correlation coefficient(r). The data was analyzed statistically using independent sample t-test and the statistical results accepted the null hypothesis of the study.  The study revealed that using problem solving method with power point and problem solving method with traditional approach both enhances SS II physics student academic achievement in refraction of light waves, also there was no discrimination of the academic achievement of male and female students when taught with problem solving method using power point. The use of problem solving method with power point has an essential effect on male and female students.  The study also revealed that problem solving method generally enhances students’ ability in solving problem in physics.  It was concluded that problem solving-ability in students is a critical variable of students’ academic achievement in refraction of light waves.
