The effectiveness of online learning using moodle in improving understanding of the equipment and completeness of electrical engineering drawings for vocational school students

This study aims to determine the effectiveness of-assisted online learning Moodle, the difference in effectiveness between-assisted online learning Moodle and WhatsApp Group, and a comparison of the effectiveness between-assisted online learning-assisted learning Moodle and WhatsApp Group in improving students' understanding of the equipment and completeness of electrical engineering drawings. This research is quantitative research with a quasi-experimental type using a design nonequivalent control group. The population in this study were all students of class X from SMK Negeri 2 Yogyakarta with competency in electrical power installation engineering expertise consisting of four classes. Classes X. TITL-1 and X. TITL-2 were determined as a random sample. Both classes were given instruments pre-test and post-test to measure students' understanding of the equipment and completeness of electrical engineering drawings. To test the effectiveness of online learning, the one sample t-test was used, the difference in effectiveness was used the paired sample t-test, and the comparison of effectiveness used the independent sample t-test. The results of this study indicate: (1)-assisted online learning is Moodle effective in improving students' understanding of equipment and electrical engineering drawings; (2) there is a difference in effectiveness between online learning assisted by Moodle and WhatsApp Group in improving students' understanding of the equipment and completeness of electrical engineering drawings; and (3)-assisted online learning is Moodle more effective than-assisted online learning WhatsApp Group in improving students' understanding of equipment and electrical engineering drawings.
