Abstract

This study aimed to develop and  validation efficiaiency  of  demonstration set of Applied digital circuit experiment . A case study electrical power sawang daen din technical college. course offered  at  2020first semester : at Office of the Vocational Education Commission. The sample were first year students in  Electricity department at diploma level at sawang daen din technical college, office of the vocational education commission. to select samples, a purposeful sampling technique were used to divide 15 students into  two groups. Pretest  and  Post – test  were  assessed to the selected samples. The result of the students’ test scores appeared to have high efficiency (at 92.33 / 88.66, higher than the previously set criteria). The students’ learning achievement of the experimental group  higher than control group at .05 . Show that , the developed motor controller  was found to be a very useful teaching tools in teaching in class and suitable for the students to practice.
