Effect of Graphical Instructional Package on Junior Secondary School Students’ Performance in Basic Technology in Omu-Aran, Kwara State, Nigeria.

Abstract

The purpose of the study was to find out the effect of graphical instructional package on junior secondary school students’ performance in basic technology, in Omu-Aran, Kwara State. The study also investigated the influence of students’ gender and ability levels on the performance of students taught using graphical illustrations. Quasi-experimental design, which involved the pre-test, post-test, non-randomized, non-equivalent control group design, was employed for the study. Sample was drawn from two randomly selected secondary schools. One intact JSS one class each from the sampled schools was also randomly selected for the study. Students from the sampled class were further stratified along gender and ability levels. Three researchers designed instruments: (i) Graphical Instructional Package (ii) Basic Technology Performance Test (BTPT), (iii) Graphical Instructional instruments was used as treatment and test instruments, respectively. The instruments were face and content validated. The test instrument, Basic Technology Performance Test was tested for reliability using test–retest method of three weeks interval Pearson Products Correlation analysis revealed a reliability value of 0.76. The three research hypotheses were tested using Analysis of Covariance. Findings indicated that students taught with graphical instructional package performed significantly better than those taught without the use of the package. It also revealed that gender of students was not a factor in the performance of students when they were taught using graphical instructional package as there was no significant difference between the performance of male and female students. Based on the findings, it was recommended that the use of graphical instructional package should be encouraged for teaching basic technology.
