1.1 BACKGROUND OF THE STUDY
Biology education was introduced in the Nigerian School Curriculum as part of the instrument for achieving national development (National Policy on Education (NPE) 1981). This was what informed its designation as part of the core curriculum at different levels of education in Nigeria. problems and prospects biology education curriculum development agencies such as the Nigerian Educational Research and Development Council (NERDC) and experts further identified and disseminated the curriculum goals or purposes of the subject in the school curriculum. These include citizenship education, reflective inquiry and biology education, (Barth-shermis, 1920; Barth-Norris, 1976; Dubey and Barth, 1980; Olawepo, 1984) among others. These broadly stated goals must be clare to, and recognized as important as well as attainable by teachers and other participants connected with the Curriculum if the intentions or purposes must be realized and the investment of effort is to be considered worthwhile (Feather, 1982; Meece, Blumenfeld, & Hoyle, 1988). These intentions or purposes are prima facie stated with clarity, but their perception or conceptualization by teachers and scholars is still in doubt as Onyabe (1980) observed that the philosophy, content and methodology of biology education has remained vague to both scholars and teachers. The incidence of conflicting conceptions of biology education curriculum is a cause for concern for three major reasons. First, the anchor or strategic position of purposes or intentions in the curriculum development process (Pratt, 1994) as illustrated in Tyler (1949) (Linear) and Wheeler (1980) (cyclic) curriculum models, among others.problems and prospects
