This study aimed to develop Google Sites as a learning media for the topic of Extracting Information from Texts for fifth-grade students at SD Negeri 54 Banda Aceh and to determine its validity, practicality, and effectiveness. The study employed a Research and Development (R&D) method using the ADDIE model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The participants were 31 fifth-grade students selected through purposive sampling. Data were collected through observations, interviews, validation sheets, teacher response questionnaires, and students' comprehension tests. The data were analyzed using descriptive quantitative analysis with percentage techniques. The results revealed that the Google Sites-based learning media achieved an average validation score of 86.66%, categorized as very valid, consisting of 86% from the material expert, 94% from the media expert, and 80% from the language expert. The practicality assessment by the teacher yielded a score of 96%, indicating that the media was very practical. Furthermore, the effectiveness test showed an average student comprehension score of 83, with 80% of the students achieving the Minimum Learning Mastery Criteria (KKTP). These findings indicate that the developed Google Sites-based learning media is valid, practical, and effective for supporting Indonesian language learning, particularly in improving fifth-grade students' ability to extract information from texts.
