Effect of STEM Problem-Based Learning on Achievement in Basic Science among Secondary School Students

This study was carried out to examine the effect of STEM Problem Based Learning on students’ achievement in Basic Science. This is in consideration of the fact that the Nigerian National Policy on Education provides that for a student to study any of the core science subjects at the Senior secondary school level, he must have to score a credit pass in Basic Science at Junior Secondary School level. Without a credit pass in any of the science subjects that make up Basic Science (Biology, Chemistry and Physics), a student cannot study any of the course in science, technology, engineering or mathematics at the tertiary education level. Unfortunately, literatures show that there is massive failure of students in Basic Science especially at the Basic      Education Certificate Examination. This study is guided by three research questions and three research hypotheses. The population for this study is junior secondary school form 2 students of Nsukka local government area of Enugu State in Nigeria. The study used random sampling technique to sample schools and employed pre-experimental research design. The sample was sub-divided into two: low ability learners and high ability learners. Data was collected at two different periods (pretest and post-test) using an achievement test constructed by the researchers. The analysis was carried out using ANCOVA, Independent Sample T-test and Paired Sample T-test using IBM SPSS version 23. The results of the analysis showed that STEM PBL is a good strategy that can be used to increase students’ achievement in Basic Science

Gender differentials in the Use of Instructional Models in Enhancing Adolescents’ Interest and Achievement in Voter Education Contents of Senior Secondary School Government Curriculum

The study determined gender effect in the efficacy of group investigation and jurisprudential inquiry instructional models in enhancing adolescent students&amp;rsquo; interest and achievement in voter education related contents of senior secondary school Government curriculum. The study adopted quasi-experimental non-equivalent pre-test, post-test control group design. Sample for the study consisted of 165 SS II students drawn from senior secondary schools in Nsukka Local Government Area of Enugu state Nigeria. Multi-stage sampling technique was used to select the intact classes from each of the schools that were assigned to the two experimental groups. Data collected using Multiple Choice Government Achievement Test (MCGAT) and Government Interest Inventory (GII) were analyzed using mean and standard deviation for the research questions and ANCOVA for testing the hypothesis at P &amp;lt; 0.05 level of significance. The findings showed that both group investigation and jurisprudential inquiry models were effective in enhancing interest and achievement of male and female students in voter education related contents in senior secondary school Government curriculum. However, group investigation proved more efficacious. These findings were exhaustively discussed with recommendations on how to manage gender factor in using student-centred instructional models in enhancing students&amp;rsquo; interest and achievement.</jats:p
