The teaching of Biology in Nigeria remains largely teacher-centered
and focuses on memorization rather than understanding of concepts.
This position paper supports cognitive constructivist models of
instruction, namely Hierarchical Task Analysis (HTA), Cognitive
Task Analysis (CTA) and the Heuristic Model Learning Strategy
(HMLS) as a systematic foundation of effective change in the
teaching of Biology. These models are based on the theory of Piaget,
Vygotsky, Bruner, and Sweller that offer practical approaches to
promoting inquiry, thinking, and creativity among students. The
paper also uses theoretical basis and empirical research studies in
Nigeria and other nations to give a synopsis of research studies that
prove constructivist and heuristic strategies are effective in
enhancing learning outcomes of students in science. It also indicates situational factors including poor instructional materials,
insufficient teacher preparedness and the existing examination
culture which hinders creativity in classroom practice. The paper
asserts that HTA, CTA and HMLS should be integrated into biology
teaching and learning, teacher education, and curriculum
development as this is crucial in attaining significant educational
change. It also argues that the transition to cognitive constructivist
pedagogy is not to be merely perceived as a theoretical project but
rather as a pragmatic reform agenda that would not contradict the
National Policy on Education (FRN, 2013) and Sustainable
Development Goal 4 on Quality Education. This paper concludes
that the implementation of these models will lead to better conceptual
knowledge, critical thinking, and problem-solving skills that can be
used to create a scientifically literate citizenry that can be found in
Nigeria by addressing potential implementation challenges and
giving practical recommendations on policies, curricula and
pedagogy
