The COVID-19 pandemic had many impacts on education. The teaching and learning process was done through distance learning and was carried out online through several online platforms and media. This study aimed to produce an independent learning media for students in the form of an online module based on the Guided Discovery Learning model in the class on chemical bonding of class X in senior high school. This study used the methods outlined in Research and Development by Borg and Gall (2003) and followed the descriptive quantitative method. The instrument used in this study was a questionnaire. The module was validated by three experts for content and language and also validated by three experts for media and graphics. The module was also trialled by 20 students in grade 10 science, 35 college students in the chemistry education program and 8 chemistry teachers. The ratings that were given by experts, students, and teachers from the validation and trial stages can be categorized as good and up to very good, so it can be concluded that the module is feasible to be used as a learning media on in the class on chemical bonding of class 10 in senior high school. Keywords: online module, guided discovery learning model, chemical bonding
