The process of learning to teach face-to-face was transformed into online learning and self-assignment during the Covid-19 pandemic. Not all learning materials can be resolved by online assignments or lectures, especially learning involving scientific processes and practicum activities. Also, the analysis of various student practicum reports shows the lack of students’ ability to analyze data based on the appropriate theory. Therefore, this research aims to develop an electronic practicum module based on scientific argumentation that can be used by students as a practicum media in the Covid-19 pandemic. The type of research used is development research with ADDIE (Analyze, Design, Develop, Implement, and Evaluate) models. The developed electronic practicum module has been validated with expert judgment by five experts through validation questionnaires. Validation poll results are then changed with a five-scale score conversion based on the ideal standard deviation to determine the product validation criteria. The calculation results show that the product is in an outstanding category and ready to be tested. Furthermore, trial activities will be conducted to determine the practicality and effectivity of product intervention on the students’ scientific arguments ability.
