Abstract:
This research aimed to develop a cooperative learning model on filter circuits for application in telecommunication engineering education. The research procedure consists of 6 steps: 1) study an existing situation of problem and learning management needs 2) develop a cooperative learning model called GIPSA learning model including Guidance, Information, Practices, Share, and Assessment 3) develop the instructional media which includes the filter simulation program, the virtual network analyzer, the passive filter circuits, and the microwave filter circuits 4) create the instructional package on filter circuits which was divided into 4 units as filter circuits principle, filter circuits design, two port network and transmission lines, and microwave filter circuits design. The instructional package comprises teachers handbook, instructional media set, and achievement test 5) implement the cooperative learning model with 22 samples who were students registered in communication network and transmission lines subject, the Bachelor of Science in Technical Education, program in electrical engineering and 6) analyze data and make conclusion.
The results of instructional media testing revealed as follows: firstly, the filter simulation program corresponded well with the Sonnet Lite simulation program that has an error less than ±5%, secondly, the operating test of the virtual network analyzer agreed with the instrument that has an error less than ±5%, and finally, the frequency response of passive filter circuits and microwave filter circuits analysis have well agreement in comparing with theory, IE3D simulation program and the network analyzer which has an error less than ±5%. The results showed that average level of opinion of experts towards the appropriation of the GIPSA learning model is mostly at high level (x = 4.38 S.D = 0.52). The instructional package has efficiency of 78.56/76.67 which is lower than standard criteria of 80/80. However, the comparison between pre-test and post-test score is significantly different at the .05 level in which the post-test scores are higher than the pre-test scores. The student opinions after using GIPSA learning model are at high satisfactory (x=4.24 S.D = 0.43 ). In conclusion, the GIPSA learning model could be applied to telecommunication engineering education with efficiency.
