A Development and Study Efficiency of Experimental Kit on Interfacing for PIC Microcontroller

Abstract

Objectives of this research were to construct and study efficiency of experimental kit on interfacingfor PIC microcontroller. Researching Tools were as follows: 1.) Experimental kit and worksheet on theinterfacing for PIC, 2.)Test and 3.) Questionnaire on satisfaction towards the experimental kit, worksheetand the study by the experimental kit on the interfacing for PIC microcontroller. Sample group was 30students who were studying in the second year of high vocational education in the field of Electronic andthe field of Electrical from Nakhonratchasima Poly-technical College. They were tested before and afterthe experiment. Data were analyzed to compare pretest and posttest score by t-test and to find the efficiencyof the kit by E1/E2. The results of the research revealed that students who studied by the experimental kiton interfacing for PIC microcontroller had the post test score higher than the pre test score at significantlevel of 0.01. The efficiency of the experimental kit on the interfacing for PIC microcontroller was at 87.33/82.92.
