Effect of Instruction Based on STEM Education on Problem-Solving Ability and Basic Power Electronics Achievement in of 2nd-Year Diploma Student

Abstract

The objectives of this research were: 1) To compare the 2nd year diploma students’ problem solving ability before and after learning by using Instruction based on Stem Education and compare after learning with criterion of 70% 2) To compare the 2nd year diploma students’ learning achievement on Basic Electronic Power subject before and after learning using Instruction based on Stem Education and compare after learning with criterion of 70%. The samples were 20 second year diploma students. one out of eight classroom from Electronic Power Department, Udon Thani Technical College. They were taught by using Instruction Based-on Stem Education method. Research instruments included 1) Six lesson plans 2) problem solving ability test. 3) Basic Electronic Power subject achievement test. The mean, standard deviation, t-test for Dependent Samples and t-test for One sample were used in data analysis. The findings of this research were as follows:  1. The 2nd year diploma students’ problem solving ability after learning using Instruction Based-on Stem Education were higher than before learning and higher than the defined criteria of 70% at .05 level of significance. 2. The 2nd year diploma students’ learning achievement on Basic Electronic Power subject after learning using Instruction Based-on Stem Education were higher than before learning and higher than the defined criteria of 70% at .05 level of significance.
