Abstract
The study explored the effects of IEPT constructivist instructional model on students’ Academic performance in Mathematics. The study adopted a pre-test post test control group design. One hundred and ninety Junior Secondary two (JS2) students in two co-educational schools in Umuahia Education Zone of Abia State were used for the study. The experimental group was taught using invitation, exploration, proposing explanation, taking action (IEPT) constructivist instructional model and the conventional method (CM) served as control. The main instrument for data collection was the Mathematics Achievement Test (MAT). The pre-test was administered before the experiment while the post-test was administered at the end of the study. One research question and one hypothesis guided the study. The research question was answered by mean and standard deviation while hypothesis was analyzed with the use of analysis of covariance (ANCOVA). The result obtained shows that students who were taught using IEPT constructivist instructional model performed significantly better than students taught with conventional method. It is recommended among other things that there should be a “paradigm shift” from the traditional expository method to active teaching/learning where teachers will be able to help students create cognitive maps, link ideas, address misconceptions and reinforce meaning.
