This research aims to construct and evaluate efficiency of experiment set for work-piece analysis based on variety of cutting edge parameters of punch-die. The parameters included clearance punch shape and inclination of punch edge that related to cutting force error in diameter and deformation of work-piece. The developed experimental set was evaluated by 15 experts using 5-point scale questionnaire which was divided into two parts: content and worksheet and experiment set design. The efficiency evaluation was done by using the experiment set to teach a sample group of 15 students. Results showed that quality of the proposed experiment set was in the highest level with average score of 4.65 (SD = 0.47). The efficiency evaluation by teaching a sample student group revealed that the efficiency was 85.43/84.00 which was higher than the criteria of 80/80 in research hypothesis. Therefore it can be concluded that the constructed experiment set could be used to enhance students’ analytical thinking in punch-die work.

The objectives of this research are to construct and determine the quality and efficiency of a simple vibration experiment package. This experiment package design was based on free body diagram of content and main knowledge analyzed from behavioral objectives. Quality of the experiment package was assessed by 12 experts in 4 aspects which included theoretical sheet experimental sheet exercise sheet and experiment device design. The efficiency evaluation was performed by a sample group of 18 students. The exercise sheet was done by the students after finishing each teaching topic and examination sheet was done after finishing all teaching topics. Results showed that quality of the constructed simple vibration experiment package was in a high level of 4.8. Efficiency of the experiment package was 80.47/81.85 which was higher than specified in the research hypotheses. Therefore the experiment package could be applied to teach in any classroom with high students learning outcome.
