This research aims to determine whether the development of discovery learning–based e-module using the professional PDF flip software integrated with the website can be an alternative in learning physics during the COVID-19 pandemic. This type of research is a preliminary study with qualitative descriptive research methods. The instrument used is a questionnaire with four categories, which is then distributed to teachers and students. The subjects in the study were physics teachers and students at SMA Negeri 3 Palu and SMA Karunadipa Palu. The data analysis used a qualitative description of the answer given by teachers and students. The results of preliminary studies show that: COVID-19 pandemic resulted in a look place online so that teachers needed teaching materials and practical media to be used without face-to-face learning.
