This research aims to develop practicum modules based on science process skills. Science process skills are an approach to learning that is designed so that students can find facts and build concepts and theories. In this science process skill, students are trained to be involved in scientific activities and become independent individuals. The development model in this study is the 4D model. The research subjects were 39 third-semester students who had taken the course on electrical measuring instruments. The instruments in this study were validation sheets (to determine product validity) and student and lecturer response questionnaire sheets (to measure product practicability). The results showed that the product, in the form of a practicum module based on Science Process Skills, was both valid and practical. The module validity was in the very valid category, with an average score of 83.14%. The practicality test for using modules for students was very practical (83.3%). The lecturer response questionnaire was in the very practical category, with a percentage of 81.25%. So, this practicum module is valid and practical and can be used to train students' Science Process Skills, especially in the material of electrical measuring instruments.

The purpose of this study was to see students' perceptions of the use of Google Classroom as a support for independent learning. The method used in this research is descriptive method by distributing questionnaires as a data collection technique. The sample in this study were students of Tadris IPA-Physics, Tarbiyah Faculty, Imam Bonjol State Islamic University, Padang. The results of this research data processing are 97.54% of respondents who filled out the questionnaire have used Google Classroom as a learning support tool, and 92.62% of them used Andorid as a learning tool. 62.30% have heard of the term independent learning, and 43,44% heard the term from a seminar held by the Tarbiyah and Teacher Training Faculty, Imam Bonjol Islamic University, Padang and seminars elsewhere. 66.39% of Respondents claim that the Google Classroom application helps them to be independent in implementing learning. 58.20% interested and 49.59% said the Google Classroom application is good and interesting. 49.18% of students stated that learning with the Google Classroom application was very supportive, 49.18% stated that they were not supported because they were constrained by the network.
