DEVELOPMENT OF SELF-INSTRUCTIONAL MANUAL FOR MAINTENANCE OF MICROWAVE OVENS FOR ELECTRICAL CRAFTSMEN IN BENUE STATE

Abstract

The study developed a self-instructional manual for maintenance of microwave oven for electrical craftsmen in Benue state. Specifically, the study determined the objectives, content and facilities required for developing a self-instructional manual for maintenance of microwave oven. Three research questions and three null hypotheses guided the study. The study adopted Sequential Exploratory Research Design, and was carried out in Benue State. A total of 96 respondents consisting of 44 lecturers/instructors and 51 electrical/electronic trade teachers were used for the study. The instrument used for data collection was: Microwave Oven Maintenance Self-Instructional Manual Questionnaire (MOMSIMQ). The instrument was face and content validated by three experts. The reliability of MOMSIMQ was found to be 0.86 using Cronbach Alpha formula. The data collected was analysed using mean, standard deviation and z-test. Findings of the study were as follows: 13 objectives were agreed to be suitable for development of microwave oven maintenance manual with a grand mean of 𝑿 = 4.43; 12 content items were agreed to be suitable for development of the microwave oven maintenance manual with grand mean of 𝑿 = 4.40 and 22 facilities were agreed to be suitable for maintenance of microwave ovens with a grand mean of 𝑿 = 4.27 among others. Based on the findings it was recommended among others that bodies responsible for development of curriculum for technical colleges such as National Board for Technical Education (NBTE) should use the objectives of the SIM to update the curriculum of electrical and electronic trade courses so as to equip the students with skills for effective maintenance and repair of microwave ovens.
