EXPLORING THE VALIDITY OF A SATELLITE TRANSMISSION AND RECEPTION MODULE USING STRUCTURAL EQUATION MODELLING APPROACH

Abstract

Satellite reception and transmission module is a form of a curriculum used for training radio, television, and electronics work craftsmen at the technical college level in Nigeria.  The validity of the modules used for training craftsmen in technical colleges is central to their suitability for the realization of set goals. This study was designed to determine the validity of a satellite transmission and reception module. To do this, an analysis centered on structural equation modeling with confirmatory factor analysis was done. A 72-item structured questionnaire was used to collect data from 195 subject matter experts. The study revealed among others that all four components of the module were retained through exploratory factor analysis. Confirmatory factor analysis was used to test the model. The results showed that the indices were: CMIN/DF = 1.459, CFI =.925, GFI =.919, and RMSEA =.077. These indicated that there was a good fit. Cronbach’s alpha was used to estimate the internal consistency of the factors, and it was acceptable for all of them. On the basis of these, the module is deemed reliable and valid. Hence, it is recommended for adoption for the training of radio, television, and electronics work craftsmen in technical colleges in Nigeria.
