Effect of Overlay Technique of Multimedia Projection on Biology Achievement of Non-Science Student of Different Scientific Literacy Levels in Polytechnics in Anambra State, Nigeria.

Abstract

The relevance of science to life and society, made the National Board for Technical Education (NBTE), to stipulate in the polytechnic curriculum that non-science students should offer  general courses in sciences.

Biology is one of the sciences they are expected to study and pass before graduation. Biology is the study of living things and their relationship with one another and with the environment.

It equips the students with useful knowledge that enables them to face challenges before and after graduation. It has been observed in polytechnics that more students enroll in non science disciplines than in science disciplines and that they consistently perform poorly in biology.

Inappropriate teaching technique was one of the several reasons given for students’ poor achievement in biology. This study investigated the effect of Overlay Technique of Multimedia Projection (OVMP) on the achievement in biology of non-science students of different scientific literacy levels in Nigerian polytechnics in Anambra State.

It examined the influence of gender on students’ achievement in biology. The interaction effects of projection technique and scientific literacy as well as gender were also examined.

Introduction

1.1 Background of Study

Science is a great enterprise which a nation depends on in order to  move forward technologically and economically. The role of science in this modern era of technology is wide and profound.

That is why science is  receiving  much emphasis at  all levels of our educational system.

The National Policy on Education (Federal Republic of Nigeria, 2004) emphasized the teaching of science at all levels in order to cultivate and develop in the minds of children the spirit of scientific and reflective thinking so that a great and dynamic economy could be built.

Science learning is expected to produce individuals that are capable of solving their problem as well as those of the society (Nwagbo & Chukelu, 2011). The actualization of the stated objectives in the National Policy on education rests on the  education  sector, particularly the school with teachers being the actual actors (Udofot, 2005).

The significance and relevance of science to life and society is not  in doubt.  This made the National Board for Technical Education (1999) to reemphasize the teaching of science to non-science students in Polytechnics, in such a  way that students will acquire fundamental knowledge in science to enable them to apply science to practical life.

The polytechnic education is a non-university tertiary education, offering a variety of technical, technological and business programmes at the National Diploma (ND) and Higher National Diploma (HND) levels leading to the acquisition of practical and applied skills as well as basic scientific knowledge.

So far, the polytechnic has expanded its scope to become involved in both research and development in wider areas of science and technology.
