Effect of Computer Assisted Instruction (CAI) On Senior High School Students’ Achievement at Pie Chart and Histogram in Core Mathematics (Published)
The study was designed to see the effect of CAI as a strategy on the academic achievement of senior high school (SHS) students in the subject area of mathematics. The sampled classes were assigned to two groups on the basis of their achievement scores in the pre-test. Two different treatments were applied during the study. The experimental group received instruction via CAI with the researcher as a facilitator while the control group was taught by the researcher using the conventional approach. Both groups took an achievement test just after the treatment was over to determine the treatment effect. Analysis of data revealed that both the CAI and the traditional approach have led to increase in students’ performance in the teaching and learning of Pie Chart and Histogram in Core Mathematics but the CAI approach has led to much gain in terms of students’ achievement than the traditional approach in the teaching and learning of Pie Chart and Histogram in Core Mathematics. It was concluded that the CAI was equally effective for the students in the experimental group because it helped students to develop Mathematical concepts adequately with limited teacher guidance
Effect of Instructional Resources on Student’s Achievement in Physics and Chemistry in Secondary Schools in Ebonyi State, Nigeria (Published)
This study effect of instructional resources on student’s achievement in physics in secondary schools in Ebonyi State of Nigeria is a quasi-experimental design that deals with pre-test, post-test, non-equivalent, control group. Intact classes were used for the study. The participants for the study were drawn from four secondary schools in Ebonyi State. The schools were selected through simple random sampling. All the physics students of SS II in the selected sample schools were used for the study. Two schools out of the four schools were assigned to the treatment group while the remaining two were assigned to the control group. Two packages were developed by the researcher for control and treatment groups. Three research questions and three hypotheses guided the work. One instrument was used for the study, i.e. physics achievement test (PAT). Mean and standard deviations were used to answer the research questions while ANCOVA was used to test the null hypotheses. The following findings were made, physics students taught with instructional resources achieved higher and better than those taught without instructional resources. There is no gender bias in terms of students achievement in physics. Among other recommendations, both male and female students should be encouraged through counselling to see physics as one of the subjects needed for the country technological break through.
