Construction and finding efficiency of multimedia package on applications of smith chart for bachelor of science in Technical Education Rajamangala University of Technology Suvarnabhumi
Abstract:
The objectives of this experimental research were to construct and find an efficiency of multimedia instructional package on applications of the Smith chart, compare learning achievement of the students between pretest and posttest after, and evaluate the learners satisfaction. The research sample were 20 students that were selected purposively from undergraduate students in electronic and telecommunications engineering program, Faculty of Technical Education, Rajamangala University of Technology Suvarnabhumi Campus. The constructed multimedia instructional package on applications of the Smith chart consists of the information sheet, Power point presentation program, computer aided instruction and achievement test.
The research results shown that the constructed multimedia instructional package had efficiency at 81.25/82.00 that was higher than the criterion set of 80/80. The comparison of learning achievement between pretest and posttest shown that posttest score was higher than the pretest score with statistically significant level of .05. The learners satisfaction level after using the constructed instructional package is very satisfy.
