Abstract

In this paper, the effect of inverted classroom approach and PowerPoint presentation on students' achievement and self-efficacy in biology has been discussed. Two research questions and two null hypotheses were formulated to guide the study. A Quasi-experiment of 2 x 2 factorial design was adopted to guide the study. 4,408 senior secondary two (SSII) Biology students in Agbani education zone of Enugu state composed the population. The sample size for the study consisted of 150 SSII Biology students. The sample was be drawn using a multistage sampling procedure. the Biology Achievement Test (BAT) and Biology Self-efficacy Scale (BSS) were used as an instrument for data collection. Three experts all from the Department of Science Education, University of Nigeria, Nsukka, validated the instruments. The reliability of BAT was determined using Kuder Richardson (K-R-21) formula which gave a reliability index of 0.79. The reliability of BSS gave an index of 0.81 using Cronbach alpha formula. Data obtained from the pre-test and post-test were quantitatively analysed. All the research questions were answered using mean and standard deviation while Analysis of Covariance (ANCOVA) was used to test all the hypotheses at 0.05 level of significance. Results from the study revealed that there is a significant effect of approaches on the achievement and self-efficacy of students taught biology using inverted classroom approach, and those taught using the PowerPoint presentation. Based on the findings, it was recommended among others that biology teachers should try to develop and adopt the use of PowerPoint presentation in their instructional delivery as it would enhance the overall achievement and self-efficacy of students in biology.

Summary

Introduction

We all rely on the environment for a variety of critical benefits which includes the air we breathe, the food we eat, and the water we drink. According to Buba, Banus and Adamu (2020), biology is a branch of natural science that provides necessary knowledge with which one can use to control or change the environment for the benefit of individual and the entire society at large This implies that biology is an everyday encounter in our activities and explains the fundamentals of every living organism. Biology is a branch of life science that is concerned with everything involving a life form, no matter how small or large including its structure, behaviour, origin, growth and reproduction (Ihekwoaba, Nzewi, Ifeagwu, Chinweuba-eze & Nduji, 2020; Nam, 2018) To this end, the importance of biology to human being and his environment cannot be overemphasized
