Development of Website-Based Learning Media Using Google Sites in Informatics Subjects of Grade X SMA Negeri 1 Alalak

Abstract

The development of website-based learning media for Informatics subjects at SMA Negeri 1 Alalak reveals several issues based on observations. The learning activities still rely heavily on lecture methods and physical teaching materials or textbooks, leading to lengthy instructional time, a lack of visual examples and images, which makes it difficult for students to understand the material, and results in boring lessons. The aim of using website-based learning media is to facilitate easier access to information and clarify computational thinking material, making the learning process more engaging and effective. This research uses the Research and Development (R&D) method with the ADDIE model, which includes: Analyze, Design, Development, Implementation, and Evaluation. In the Analyze phase, the learning goals are reviewed to ensure alignment with  basic competencies. The Design phase involves the initial design of the media. In the Development phase, validity testing of the media and material is conducted. The Implementation phase includes small-scale and large-scale trials. Finally, the Evaluation phase assesses the developed learning system to gauge the results of the implementation, specifically through evaluating student learning outcomes. The research findings indicate that the learning media is considered "Feasible" for use in Informatics subjects with computational thinking material, as the material validation received a score of 4.2 (category "Feasible"), media expert assessment reached a score of 4.3 (category "Very Feasible"), and small-scale and large-scale trials each received scores of 4.3 and 4.35, respectively, both in the "Very Feasible" category. The evaluation results show an average learning outcome of 92.9. Therefore, it can be concluded that the learning media is both feasible and effective for use in teaching
