This study was designed to investigate the effect of mathematical modelling on students’ achievement and interest in geometry. The study also examined the influence of gender on students’ achievement and interest in geometry. Four research questions and six hypotheses were formulated and tested for the study. The study employed a non-equivalent pretest-posttest quasi-experimental design. The population comprised of 2,644 senior secondary one (SS 1) students found in 48 government owned secondary schools in Obollo-Afor Education zone. The study sampled one hundred and seventy students randomly selected from two schools. Two classes from each of the schools were randomly assigned to control and experimental group. This implies that a total of four classes were used for the study. Data on geometry achievement and interest were obtained using Geometry Achievement Test (GAT) and Geometry Interest Scale (GIS) respectively. The GAT, GIS and lesson plan constructed for the study were face and content validated by experts in the field.
