The population consisted of 6,478 senior secondary 3 (SS3) students from 13 state financed<br>senior secondary schools in Port Harcourt. Stratified random sampling was conducted to select 3 schools (one school each from<br>2 mixed schools, 5 boys’ schools and 6 girls’ schools). The sample for study was 300 SS3 students from the 3 randomly<br>selected schools. The instrument used for data collection was the Self-Description Questionnaire 111 (SDQ 111) developed by<br>Marsh (1992) which contains 13 self-concept facets out of which 2 facets (Mathematics, and General Academic) where adopted<br>for this study. The subjects were tested in Mathematics and scores obtained. The general average scores of the students on<br>their promotion examination from SS2 to SS3 were extracted from their school records. The Person’s Product Moment<br>Correlation analysis was used to answer the research questions, while the transformed t-test was used to test all the 3<br>hypotheses formulated for this study. The results of the tests indicated that Mathematics Self-concept is significantly related to<br>Mathematics Achievement, General Academic Achievement and General Academic Self-concept. The main implication of the<br>findings of this study is that self-concept and Mathematics, and General Academic achievement of students are so strongly<br>related that a change in self-concept facilitates a change in achievement. It was therefore, recommended that educational<br>programme designers and developers, teachers, parents and students should make self-concept development of students an<br>educational aim as important as academic achievement.</p>}, number={4}, journal={Journal of Educational and Social Research}, author={Obilor, Isaac Esezi}, year={2011}, month={Nov.}, pages={39} }
