The construction and efficiency validation of the instructional package using multimedia on radio transmitter and antenna vocational certificate curriculum of vocational education commission
Abstract:
This research aimed to construct and to validate the efficiency of an instructional package using Multimedia on Radio Transmitter for Vocational Certificate and to compare learning progress of the students between before and after using this instructional package. The constructed instructional package consisted of a teachers handbook, teaching aids, exercises and tests. Samples were 20 students registered in the cademic year 2009, second semester at Saint Johns Polytechnic School. They did the pre-test before taking the course and worked on the test after each unit, and then they did the post-test. The scores were calculated for the efficiency with the formula E1/E2. The learning progress was analysed by comparing between pre-test and post-test and t-test was used for testing statistically hypothesis. The results revealed that the in structional package had the efficiency of 76.80/72.30 which lowers than the set criterion 80/80. The comparison of the mean scores between pre-test and post-test found that there were statistic significant difference ( ∝ = .01 ) and the mean scores
of learning progress between the higher and the lower groups were not different ( ∝ = .05 ) .
