Effect of Computer- Based Multimedia Presentation on Senior Secondary Students’ Achievement in Agricultural Science

摘要

The study was carried out to determine the use of computer-based multimedia presentation on Senior Secondary School Students’ Achievement in Agricultural Science. The study was a quasi-experimental, pre-test, post-test control group research design type, using intact classes. A sample of eighty (80) Senior Secondary School One (SS II) students was selected from two secondary schools in Ijebu-Ode Local Government Area. The instrument for data collection was a 20-item multiple choice Agricultural Achievement Test (AAT) developed by the researchers for the purpose of measuring students’ achievement in agricultural science. The instrument was validated by experts and subjected to reliability test and this yielded a reliability value of 0.85. The achievement tests were administered to the two groups before and after the treatment and the scores so obtained were analyzed by t-test statistical method. A self developed procedural instrument named "Computer - based multimedia maize breeding packages (CBMBP)" was used to teach the experimental group, while conventional method was used to teach the control group. In the study, three research hypotheses were tested. The result of the study revealed that the computer-based multimedia presentation was found to be more effective than the conventional method because significant difference exists in the mean achievement scores of students taught using the computer-based demonstration mode compared to those taught using the conventional method. It was recommended that recruitment of competent ICT teachers, adherence to the application of appropriate instructional technologies to capture and sustain students’ interest, creation of good learning environment with adequate improvised instructional materials in all secondary schools will enhance achievement and good success in vocational subjects. Ministries of education, curriculum developers should outline appropriate ICT-based instructional approach that could be used by teachers to teach any topic highlighted in the agricultural science curriculum.
