Impact of Multimedia and Hypermedia Instruction on Teaching Basic Electricity Technology: Case Study of Government Technical Colleges in Oyo State, Nigeria

Abstract

This research was carried out to ascertain the impact of Multimedia and Hypermedia on teaching
Basic electricity technology subjects in Government Technical Colleges in Oyo Sate, Nigeria.
Quasi experimental design involving pretest, posttest, non-randomized comparison group was
used for the study. Two research questions and two hypotheses were raised to guide the study. A
total of one hundred (100) final year students of Electrical/Electronics Department from the five
Technical Colleges in Oyo State constitute the population of the study. Achievement test with 40
test items involving application of multimedia and hypermedia resources was used as the
instrument for data collection. The instrument was subjected to face and content validity by ICT
experts in Industrial and Technology Education. The reliability of the instrument was determined
using the Pearson Product Moment Correlation and the Correlation Coefficient was found to be
0.85, while the Kuder-Richardson (KR20) formula was used to determine the internal consistency
and the result obtained was 0.78. Mean and Standard Deviation were used to answer the research
questions while the Analysis of Covariance (ANCOVA) was employed to test the hypotheses that
guided the study. The findings from the study revealed that multimedia and hypermedia
instructions were effective in enhancing students’ achievement in Basic Electricity Technology.
The study also found out that there was a significant difference between the main effects of gender
(male and female) on students’ achievement in Basic Electricity. The study recommends for the
adoption of multimedia and hypermedia instructional resources and also advocate for training and
retraining of the teachers and students on effective utilization of multimedia and hypermedia
instructions resources.
