Development and Usability of Transistor Module using Tinkercad among UPSI Physics Trainee Teachers

This study was conducted to develop Transistor module using Tinkercad and to study the usability of Transistor modules using Tinkercad among trainee Physics teachers of Universiti Pendidikan Sultan Idris (UPSI). This study is a developmental design study using the ADDIE model and developed based on Constructivism theory. A total of 84 samples from UPSI Physics trainee teachers were taken as respondents through convenient sampling method to study the usability of the module. The research instruments involved were an expert validity assessment form and a usability questionnaire. The method used to analyze the validity using the expert consent percentage method. Statistical Package for the Social Sciences (SPSS) application was used to obtain the value of Cronbach's alpha reliability coefficient while the data for the usability questionnaire were analyzed using descriptive statistical analysis data to obtain the mean and standard deviation. As a result of the study, the value of expert agreement for modules and instruments is high with values of 94.5% and 92.7%. For the research instrument got a high reliability value of 0.93. The findings of the study also show that this module has good level of usability (M = 4.67, SP =0.46). Therefore, this module is suitable to be used as a study aid for the Transistors subtopic for Form Five Physics.
