Abstract:
The research aimed to develop the Multimedia Instructional Package on
Communication System 2 (MIP-CS) and to validate its efficiency. The developed MIP-CS
consisted of teachers handbook, teaching aids, exercises and test. Sample were 21
students registering in the second semester of the academic year 2008 at King Mongkuts
University of Technology North Bangkok. The scores were used to find the efficiency of
the MIP-CS and then to find the learning achievement.
The results showed that the efficiency of MIP-CS was at 78.30/82.11 that was
lower than the criterion set 80/80. The attitude of the students after learning through
MIP-CS was in high level. However the comparison of the scores between pre-test and
post-test was statistically significant difference at .01, learning achievement after using the
developed MIP-CS was higher than before using it, and students had more knowledge
after using our instructional package.
