However, since the pandemic, the activities of science in junior high school have not run as they should; this has an impact on the quality of learning where currently teachers are unable and have difficulty implementing an independent curriculum in science learning. Thus, this activity aims to empower groups of science teachers who are members of the Science teachers through Lesson Study-based assistance in improving the quality of learning through increasing teacher knowledge about the implementation of the independent curriculum and independent learning platform, as well as increasing teacher creativity in making student diagnostic assessments with the ultimate goal of producing electronic modules of science learning based on the independent curriculum. The output resulting from this service activity is the empowerment of partners through increasing knowledge and skills. Another impact of this mentoring activity is that teachers become more creative and innovative in developing science learning by utilizing information technology.
