Teaching and Learning Development for Enhance of Electric Vehicle Technology Competency

This research aimed to develop and find efficiency of teaching and learning to enhance competency of electric vehicle technology.The sample group for this research comprised of 20 fourth-year students from Mechanical Engineering Program, Faculty of Engineering, Rajamangala University of Technology Lanna Phitsanulok, selected by purposive sampling.The tool used in this research was an instructional package for enhancing competency of electric vehicle technology.Data collection started by testing students' knowledge base with pre-learning test.Then, the instructional package developed by the researcher was used to teach students.During the teaching of each topic, the students had to do exercises and practice with worksheets in order to measure progress during learning.After completing every topic, the students did theoretical test and practical test again.Scores from exercises, theoretical test and practical test were statistically analyzed to find efficiency of teaching and learning with the developed instructional package.Statistics used included percentage, means, t-test and efficiency test.Results showed that efficiency of theoretical part was 86.13/82.03and efficiency of practical part was 82.60/85.32 which were higher than the specified 80/80 criteria.
