The use of information technology plays an important role in online learning. Schools must be prepared to learn to use the learning method from home during the pandemic. One alternative is to use a computer as a learning medium. Learning by utilizing computer media is very much needed in this pandemic era. This study aims to produce an ethnoscience-integrated android-based learning media that is feasible, practical, and effective to improve students’ scientific argumentation skills. This study uses a 4D development model procedure. The product developed consists of a syllabus, lesson plans, android, and evaluation instruments which are validated by three expert validators. The data instrument consists of a feasibility assessment questionnaire, the practicality of learning, and a scientific argumentation ability test instrument. The validation results show that the average percentage of syllabus eligibility is 87.9% with very feasible criteria. The average percentage of eligibility for the lesson plan is 88.6% with very feasible criteria. The average percentage of android media eligibility is 85.1% with very feasible criteria. The average percentage of the feasibility of scientific argumentation instruments is 84.6% with very feasible criteria. The results of the practicality test showed that the student response was 78.6%, the teacher response was 84%, and the learning implementation was 83% with efficient criteria. The effectiveness of learning using ethnoscience-based android media shows an increase in scientific argumentation skills on moderate criteria. Based on this description, it can be concluded that this ethnoscience-based android media is feasible, practical, and sufficient to improve scientific argumentation skills, especially during the Covid pandemic.
