Abstract


Mechanical Engineering Craft Practice (MECP) is one of the trades taught at Technical Colleges leading to the award National Technical Certificate (NTC) in Nigeria. Sand casting is among the contents covered by the NTC curriculum. However, due to inadequate material resources such as teaching aids, the objectives of MECP trade has not been fully achieved. Therefore, in order to complement the instructional resources, a video for teaching sand casting was developed and evaluated. Therefore this paper reports the findings of the study as a result of developing and evaluating sand casting instructional video package. Four research questions guided the study. Both the instructional video and test instruments were validated by a team of experts. Primary data collected using video and still camera and its accessories, and the Province Princes Edwards Island Department of Education DVD/Video Evaluation form. The data collected were analysed using Multi stage approach, Frequency count and Mean. The results from the study revealed that the developed sand casting instructional video was appropriate and suitable for use in teaching and learning in technical colleges in Nigeria. Hence it was recommended that government should assist TVET teachers/instructors with the necessary materials including funds to develop and evaluate instructional video for teaching and learning technical courses in Nigeria.
