Abstract


Development Questionnaire II (Student) is to obtain feedback from respondents, the students associated with the Program Implementation Evaluation Diploma in Mechatronics Engineering at the Polytechnic towards Industrial Requirements in Malaysia. This study was conducted to produce empirical evidence about the validity and reliability of the questionnaire II (Student) using Rasch Measurement Model. A pilot study was conducted at the Department of Mechanical Engineering, Polytechnic Kota Kinabalu, Sabah on 38 students in their final semester of a diploma program in Mechatronic Engineering. Validity and reliability of the questionnaire II (Students) were measured using Rasch Measurement Model Winsteps Version 3.69.1.11. Rasch analysis showed respondents reliability index is 0.97 and reliability index is 0.91.From the point of polarity items, each item can contribute to the measurement because the PTMEA CORR each item above 0.30, which is between 0.30 to 0.81. Appropriateness test shows 23 items in the questionnaire should be dropped and the second item MNSQ repaired because the outfit has to be outside the range between 0.6 to 1.40. These findings provide the dimensions of the construct validity of the questionnaire, which constructs the implementation of the teaching and learning process, use of facilities and equipment for teaching and learning and assessment. Rasch Measurement Model has shown that the questionnaire II (Students) have a high validity and reliability for use in measuring the evaluation of Diploma in Mechatronics Engineering Program implementation at Polytechnic College in regards to the Industrial Requirement in Malaysia.
