Abstract

This study uses a quasi-experimental research design and the Successive Approximation Model (SAM) for research and development (R&D). In twenty (20) states, including the Federal Capital Territory (FCT) Abuja in Northern Nigeria, technical colleges providing radio television and electronics jobs were the sites of the study. The study's sample comprises 782 NTC1 students from fifteen carefully chosen technical colleges that provide RTVEW. 460 National Technical Certificate year one (NTC1) RTVEW students from 11 classes in 11 coeducational schools in Northern Nigeria's Education Zone made up the study's sample. Out of the fifteen coeducational Technical colleges in the Education Zone of Northern Nigeria, eleven coeducational schools were chosen using a simple random sample technique. A structured questionnaire on RTVEW with the title "Practical Guide for National Technical Certificate Students of RTVEW Questionnaire" (PGNTVCSRTEWQ) was the tool utilized to collect data for this study. On PGNTVCSRTEWQ, face and content validation were conducted. Twenty-seven specialists from the Department of Industrial Technology Education verified the instrument. Federal Technological University in Minna. While in Nigeria, twenty-five (25) randomly selected technical college students offered RTVEW. The data was analyzed using I-CVIs, SCVI/UA, and S-CVI/Ave, and it was discovered that the content validity index at the third round of validation is 0.96. The practical guide for National Technical Certificate (NTC) students studying radio, television, and electronics works underwent a content validity analysis, and the results showed that the instrument met the requirements for a sufficient level of content validity. The comprehensive evaluation process, which included several rounds of expert reviews and the computation of numerous validity indices, led to this conclusion. The results show that, in spite of certain difficulties, the instrument is reliable and appropriate for use in teaching.
