ABSTRACT
The aim of this research is to develop electronic modules with discovery learning models that contain learning stages, such as stimulation, problem identification, data collecting, data processing, verification and generalization. This electronic module is proposed as a media and learning resource to improve Higher-Order Thinking Skills (HOTS) of students. The improvement can be done by students, while evaluating themselves in an evaluation section on the electronic module, which contains HOTS problems. Analyzing, synthesis and evaluation are aspects of HOTS problems. The research method used is Research and Development (R&D) with Analysis, Design, Development, Implementation and evaluation (ADDIE) models. Seen in terms of module characteristics, the percentage of achievement from experts is 89.63% for self-instruction, 97.14% for self-contained, 91% for stand alone, 95.6% for adaptive and 93.3% for user friendliness, with an average percentage of module characteristics reaching 92.73%. The results show that the control class N-gain test was 0.357413 and the experimental class was 0.449905. Two classes were tested using a t-test with a test result of 4.02. The conclusion is that the development of electronic modules with a discovery learning model is feasible for use as media and sources of independent learning and can have a positive influence on improving HOTS of students in harmonic oscillation material.
