Pre-lesson assignments and formative assessment strategies with interactive invention instruction on low achievers in physics

Abstract
This study examined the impacts of Interactive–Invention Instruction with Pre-Lesson Assignments (PLA) and Weekly Formative Tests Assessment Strategies (WFTAS) on students with low achievement in Physics in Ibadan, Nigeria. Pre-test post-test quasi-experimental research design and ninety Senior Secondary II students participated in the study. Two experimental groups and control were taught using Interactive-invention instruction, in addition, experimental group (1) was exposed to PLA while group (2) was exposed to WFTAS but the control group was only taught with interactive-invention instruction. Physics Achievement Test (r=0.89) and three teachers guides were instru-ments used while analysis of covariance (ANCOVA) was used to analyse the data. The treatments had significant main effect on low achieving students’ achievements in physics (F(2,75) =9.205; p
