Effect of Concept Mapping on Secondary School Students’ Achievement and
Retention in Physics in Enugu State.
This study sought to determine the effect ofconcept mapping on secondary school students‟ achievement and retention in physics. Four research questions and six hypotheses guided the study. Pretest-posttest non randomized control group design was adopted for the study. The study was conducted in Agbani education zone of Enugu State, where a sample of one hundred and fifty-six (156) senior secondary school one (SSS 1) students was drawn from four intact classes. Technique adopted for sampling was purposive multistage stratified random sampling. Instrument used for data collection was Physics Achievement Test (PAT). The instrument was constructed by the researcher and validated by three research experts. PAT yielded a stability coefficient of .71 obtained through test –retest approach. PAT also yielded a reliability coefficient of .65 obtained by Kudar-Richardson 20 formula. Research questions were answered using mean and standard deviation. Hypotheses were tested using Analysis of Covariance (ANCOVA). Major findings of the study showed that the experimental group achieved higher and retained more physics than their counterparts in the control group. Also male and female students did not differ significantly in their achievement and retention in physics. It was recommended that concept mapping be used in teaching secondary school physics.
