Development and Validation of New Closed-Circuit Television Systems Contents for Satellite Transmission and Reception Module for Technical Colleges in Nigeria

Abstract

The study developed new closed-circuit television systems contents for satellite transmission and reception module for technical colleges in Nigeria. The study adopted a four stage research and development research design. A sample of 228 was obtained using; purposive and random sampling techniques from a population of 346. Data were collected using a structured questionnaire that had a reliability coefficient of 0.83. The data collected from the respondents were analysed using mean statistics, standard deviation and t-test. The study revealed new cognitive and psychomotor skills contents for the installation and troubleshooting of closed- circuit television systems for satellite transmission and reception module including: applications of closed-circuit television systems, operational requirements for installing closed-circuit television, and best practices for setting up and termination procedures for display screens, among others. The study also revealed that there was no significant difference between the mean responses of Electrical/Electronic industrial personnel and teachers on the new cognitive and psychomotor skills contents for the installation and troubleshooting of closed-circuit television systems. It was recommended that NBTE should consider splitting the current satellite transmission and reception module into four composite parts, such as closed-circuit television cameras installation and maintenance, which would cater for a more focused acquisition of skills.
