During the COVID-19 pandemic, internet technology was critical to develop. As a result, schools are required to incorporate information technology into the learning process. The goal of this study was to determine how lower grade students used Google Classroom as an integrated thematic expansion medium. The descriptive qualitative method and case study approach were used in the research. Data collection methods include observation, interviews, and documentation. One of the online learning solutions is to use Google Classroom as an interactive learning media based on e-learning to assist teachers and students in the teaching and learning process from home in support of ICT-based learning. The findings revealed that the use of Google Classroom as a medium of learning in lower grades has not been maximized for these students; it is necessary to become accustomed to applying learning using Google Classroom learning media for face-to-face online meetings, learning materials, and learning evaluation so that teachers can explore the learning media used during the COVID-19 pandemic. The findings of this study have implications for developing a thematic tracking system that is more effective and appropriate for teachers and students in learning during the COVID-19 pandemic.
