Introduction
1.1 Background Of The Study
The importance of science as a requirement for technological development cannot be over emphasized. Science is a way of solving problems. The study of science helps us to answer the how, what, where and why of our surroundings. According to Shaibu (2008), science is defined as human activity that leads to the production of a body of universal statements called laws, theories, or hypotheses which serve to explain the observable behavior of the universe or some aspects of the universe. Science is important in the development of a country. It is also the root of economic and technology development. Science helps to eliminate ignorance and superstition among the Populace. .Science and technology are conceived as the two sides of the same coin, technology itself is the result of scientific knowledge (Ochu, 2010). National development cannot take place without emphasis on science and technology.
According to Acquaye in Oboh (2012), today apart from raising man's standard of living, science has enabled developed nations to improve on their desire to match the fact of advancement made in industrialized countries in all facets of development. These include health, agriculture, Shelter, communication, transportation, environment and many more. Modern development is no longer possible outside, the frame work of science and technology, hence the need to teach science in schools is in line with this observation. Some states in Nigeria such as Oyo, Kano, Niger, Plateau, Sokoto and Kaduna have established special science schools in order to popularize science and make its teaching and learning more effective.
Science generally consists mainly of the three basic science subjects via, biology, chemistry, and physics. According to Obeda (1998) and Oboh (2012), Science has contributed to human civilization by providing.
- Information on the care of the human body
- Breakthrough in medical science by the discovery of new drugs and invention of excellent diagnostic method;
- Means of prevention and cure of human diseases;
- Breakthrough in agricultural techniques and practices, development of improved varieties of crops, control of large number of diseases and pests of agricultural plants and animals.
- Breakthrough in field of engineering
- Improvement in man's environment and supply of basic needs such as food, shelter, clothing as well as recreation, transportation, communication and a host of others. With the aid of science, new machines and processes have been developed, which not only help to improve the quality of living but also enable science itself to open new fields.
According to Usman (2010), Education in science is man's attempt of trying to understand the world he lives in for the primary purpose of survival and improvement of the quality of his life. Ukwungu (2004) observed that Science Education in Nigeria has continued to be ineffective in promoting the Socio-economic transformation of our nation. Nworgu (2001) also observed that contrary to the spirit of Science, the Science teachers still teach without the necessary activities needed for proper understanding of the concepts. It becomes necessary therefore, for the teacher to know how Science can be presented through the use of appropriate method of teaching.
Biology is the study of life. It is the science that studies living things and it is therefore very vital to man (Fatubarin, 2003). Biology like any other science subject, uses the scientific method usually characterized by accurate observation, careful analysis and faithful recording among others. The teaching and learning of science by effective use of scientific methods in solving problem, enable the students to develop scientific skills and attitudes.
The Federal Ministry of Education of Nigeria in the revised National Policy on Education (FRN, 2013), stressed the need for the teaching and learning of Science Subjects in Secondary Schools. Biology, English Language and Mathematics are made compulsory as basic Subjects that all Students must offer. This has attracted large enrolment of Students in Biology, compared to other Science Subjects in the Senior Secondary Certificate Examination, as was stated by Timothy (2013). As a result of this a large number of Students without interest in Biology, study and sit for the Biology examinations, which has led to Poor Performance in Biology at the Senior Secondary School level. This Under performance / Under achievement is evident in (Table 1.1), where Senior Secondary School Certificate Examination (SSCE) results of Schools in Kaduna State from 2008 to 2012 are outlined below. This Examination results released revealed that there were poor performance of students in Biology especially in 2011 only 41% of the 78,616 candidates that sat for the WASSCE. May/June passed the examinations. The remaining 57% Failed, of those that sat for the Examination.
