This paper discusses the application of contextual physics teaching materials assisted by android-based virtual labs to improve students' science process skills during the learning activities in the Covid-19 pandemic. These contextual physics teaching materials are applied to students from two classes, model and implementation class.Based on the research data, the comparison of students' pre-test and post-test results in the model and implementation class was comparable. Students in those classes experienced an improvement in science process skills. The research data signify that the application of contextual physics teaching materials assisted by androidbased virtual labs can improve students' science process skills during the learning activities in the Covid-19 pandemic.
This is a quasi-experiment research with a quantitative approach. This research aimed to examine the effect of contextual physics teaching materials assisted by android-based laboratories in improving students' conceptual understanding. The sampling in this research were students in class XI IPA 4 (as a modelling class) and XI IPA 6 (as an implementation class) at SMAN 1 Muntilan. The sampling technique used is purposive sampling. The conclusion of this study is the use of contextual physics teaching materials with the help of an android-based virtual lab can improve students' conceptual understanding. These results prove that contextual physics teaching materials assisted by android-based virtual labs are effectively used to improve students' conceptual understanding. This finding is an effective alternative to learning in distance conditions and can also be used face-to-face.
