EFFECT OF CONSTRUCTED MODEL OF HUMAN EYE ON SECONDARY SCHOOL BIOLOGY STUDENTS LEARNING OUTCOME IN BOSSO LOCAL GOVERNMENT AREA NIGER STATE

Abstract

This study investigated effect of constructed model of human eye on secondary school biology students learning outcome in Bosso Local Government Minna. The study sample consisted of 160 SS2 biology students randomly selected from a population of 5,656 students drawn from 20 public schools. An instrument designed and developed by the researcher known as Biology Achievement Test (BAT) was validated by some senior lecturers in School of Science College of Education Minna, A Lecturer from Science Education Federal University of Technology Minna. The instrument used was tested and certified to be reliable at 0.05 coefficient. Quasi-experimental design was adopted which involves four groups: two experimental groups and two control groups. The experimental group was subjected to treatment using constructed model of human eye but the control group was taught without the constructed model. Four null hypotheses were tested using t-test statistics. The following major findings were made: There is a significant difference between the mean achievement scores of students taught using constructed model of human eye (EG) and those taught without the use of the model (CG).There is no significant difference in the mean achievement scores of students taught biology concepts using constructed model of human eye based on gender. There is no significant difference in the mean retention scores of students taught with constructed model of human eye and those taught without the constructed model. There is no significant difference in the mean retention scores of students taught Biology using constructed Model and those taught without the Model. On the basis of these findings some recommendations were made, one of which is teachers should make use of constructed model to facilitate the teaching of biology at secondary school.
