IMPROVING STUDENTS’ ACHIEVEMENT IN MATHEMATICS THROUGH ONLINE PLATFORM DURING COVID-19 PANDEMIC: A CASE OF REPEATED MEASURES

The study investigated on improving students' achievement in mathematics through online platform during covid -19 pandemic: A case of repeated measures. The study adopted one-group time series research design. Sample size of 280 Mathematics students were used for the study from the population of 4263 SS1I Mathematics students in Nsukka education zone of Enugu State, Nigeria. Mathematics Achievement Test was used for the conduct of the study. Face and content validation of the instrument was established. Internal consistency reliability estimate of .92 was obtained using Kuder-Richardson 20 (KR-20) while estimate of stability of 0.88 was obtained. At three weeks interval, the subjects were pretested twice before the experiment and post tested twice after the experiment. In order to address the research questions, the data was analyzed using means and standard deviations, and repeated measure analysis of variance was used to evaluate the hypotheses at the 0.05 level of significance. The study found that students who were exposed to an online platform had higher mean achievement scores than students who were exposed to a traditional (lecture) method.
