Design and Development of a Customized Computer Assisted Instruction (CCAI) Model for Teaching Science Subjects in Nigerian Senior Secondary Schools

This research work focused on the Design and Development of Customized Computer Assisted Instruction (CCAI) Model for Teaching Science Subjects in Nigerian Senior Secondary Schools. As science education is yet to achieve its target objective of achieving sustainable science education for industrialization, there is need to find out the causes of the problem and proffer solution to it. Survey method was used to find out the current scenario in the teaching and learning of science subjects in Nigeria secondary schools. Three hundred copies of questionnaire were used to collect data from a sample of 20 secondary schools across the six geo-political zones of the country. Three research questions and two hypotheses were formulated that guided the study. Data collected were analyzed using mean and standard deviation. Chi-square was used to test the hypothesis. The major finding, among others showed that all the schools in the six geo-political zones still lacked science teachers, particularly in physics subject. This finding therefore justified the need to find an alternative solution to the teaching of science subjects in our schools. The researchers therefore, designed and developed a customized CAI for teaching science subjects at the senior secondary school level using physics as case study. The methodology adopted for the design of the CAI software was top down, and the structured systems analysis and design methodology. Visual Studio 2015 and Microsoft SQL server 2013 were also used to develop the model CAI. Experimentation of the software by students offering physics recorded huge success, thus raising the hope that full utilization of the software will go a long way in addressing the lack of science teachers, and as well aid students' understanding of the subject for improved academic performance.
