Abstract
This research aims to 1) Develop an online learning materials on "Disassembly and Assembly of Small Engines" 2) Assess the quality of the online learning materials and 3) Evaluate the effectiveness of the online learning materials by comparing the learning outcomes of the control group and the experimental group of enlisted soldiers. These two groups were total sample size of 20 participants by using true experimental design. Each group was divided into 10 persons per group. The research tools were consisting of online learning materials, lesson plan sheet, assignment sheet, examination sheet, scoring sheet, and quality assessment sheet. The t-test (Two Sample for Means) of statistical method was employed to analysis different mean score of two groups. The research results revealed that the developed online lesson media evaluation by experts was highly suitable specially in terms of interactivity mean score 3.80 S.D. 0.30 design mean score 4.10 S.D. 0.49 usability mean score 4.30 S.D. 0.44 and content mean score 3.80 S.D. 0.25 from five rating scale questionnaire, respectively. The effectiveness of learning outcome from the experimental group was 82.46% over the 80% criterion. The comparison of learning outcome of control and experiment group was different with statistical significant at the 0.05 level. The learning outcome from experiment group was higher than control group. This research can conclude that the developed online learning materials can applied in professional training to review before practice.
