Students’ academic performance in science at both the secondary and tertiary level of this schooling system has been to many factors. One of these factors is teacher’s strategy of teaching. That is why this paper is advocating for a shift in the pedagogy of teaching in science education. Based on the weaknesses of the lecture and other teaching pedagogy in science, the paper considered Peer Instruction (PI) to be a better alternative. Peer Instruction is a research-based pedagogy developed for teaching large introductory science courses. It is a method created to help make lectures more interactive and to get students intellectually engaged with what is going on. Lectures in PI consist of short presentations on key points, each followed by short conceptual questions called ConcepTest, typically posed in a multiple-choice format, on the subject being discussed. The choice of PI is based on several research studies that confirmed its effectiveness. The underpinning theories for this paper are social constructivism and constructive controversy because they viewed learning through interactions and argumentation. The paper suggested some recommendations. Keywords: teaching pedagogy, authentic learning, rote learning, peer instruction, ConcepTest. INTRODUCTION Nigerian school system is divided into Primary, Secondary, and Tertiary school. Pupil spends six years in primary before they move to a secondary school where they also spend six years. The six years of secondary schools are divided into three years of Junior Secondary School (JSS) and three years of Senior Secondary School (SSS). The last level of the educational system is tertiary school level. These are the University, Polytechnics and the College of Education. Number of years spent in these institutions depends on the type of course. However, for the science education, irrespective of the kind of the institution, the maximum year allowed is 5years. Science education is not clearly defined in primary school in Nigeria, except for the study of basic science technology. In the secondary schools, there is basic science at the JSS level. At the senior secondary School (SSS) level, there is biology, chemistry and physics taught separately. At a tertiary level, the main focus of this paper, science education is clearly defined to be biology, chemistry, and physics studied together with the principle and method of education. Many teachers handling the science subjects in most of our secondary schools specializes in science, not in science education (Omosewo, 2009). Therefore, these teachers lacked appropriate instructional strategies for teaching and often used lecture method. Science education in Nigerian schools is faced with many challenges, one of such challenges is the
