EFFECT OF POWER POINT PRESENTATION ON THE ACHIEVEMENT OF PHYSICS STUDENTS IN COLLEGES OF EDUCATION, BORNO STATE, NIGERIA AYODELE G. FASANYA (Ph.D) DEPARTMENT OF PHYSICS, COLLEGE OF EDUCATION, WAKA-BIU BORNO STATE, NIGERIA fasanya798@gmail.com 08036524713
Abstract: The teachers’ basic tools for displaying lectures are through chalkboards, bulletin boards, transparencies with an overhead projector and power point presentation. The effect of power point in teaching physics is continuously debated. However, both supporters and opponents have insufficient empirical evidence. The present study was then conducted to find out the effect of power point in teaching undergraduate physics students in Colleges of Education in Borno State. This study adopted quasi experimental, specifically pretest, posttest nonequivalent control design. Simple randomization was used to select one College of Education out of the three existing Colleges in the state. The population for the study comprised all the NCE II physics students in the three Colleges, while the sample size consisted of 43 NCE II students offering physics in the selected College of Education. The sample size was divided into two groups and a selected-content based lecture on Mechanics and Properties of Matter II (PHY 213) was delivered. For one group (Experimental), lecture was delivered using power point presentation, and for the other group (Control), lecture was delivered using tradition lecture method. The instrument used for data collection was Single-based Multiple Choice Questions (MCQs). One research question and one hypothesis guided the study. The hypothesis was tested at 0.05 level of significance. Statistical analysis was done using Mean, Standard deviation and student’s t-test. The results showed that students who were taught using tradition lecture (TL) method achieved significantly higher than their counterparts who were taught the same contents using power point presentation (PPP). Based on the results, it was therefore, recommended that lecture method should be adopted to teach physics in Colleges of Education in Nigeria. Keywords: Achievement, Lecture Method, Power Point Presentation.
1. INTRODUCTION The 21st century is the century of society’s movement towards knowledge centredness, knowledge sharing and evolution in basic concepts and dimensions of life, such as education and training. In the last 20 years, the application of various approaches, models and strategies to improve students’ achievement through the presentation of visual information with lectures has gained prominence (Mojgan, Sanaz, Balaye & Rahim, 2016). To emphasize particular point, many lecturers use written materials presented on a chalk board, white board or by power point presentation (PPP) on computers. In fact, many Colleges and Universities have rooms or mobile carts that are equipped with technology that is required for any instructor to display information in this manner (Erdemir, 2011).
