Development of Google Sites-Based Learning Media Integrated with Wizer.me Using CBL-STEM Approach for Relations and Functions
Advances in digital technology call for innovative, interactive mathematics learning media to facilitate the understanding of abstract concepts, such as relations and functions. This research and development study aims to describe the design process, the level of technical feasibility, and the effectiveness of using Google Sites-based learning media integrated with Wizer.me interactive digital worksheets. Using a descriptive method in a limited-scale pilot study, the study subjects included 32 eighth-grade students from Class VIII-F at SMP Negeri 15 Semarang and a mathematics teacher serving as an expert validator. Data were collected through validation sheets, classroom observation, post-instructional interviews, student reflections, and learning outcome assessments. The results indicate that the learning medium met the criteria for “highly suitable,” with a validation score of 86.76% from the subject teacher; the implementation process was effective, with an average class assessment score of 76.16; and the majority of students provided positive feedback, although internet infrastructure constraints remained the primary technical challenge in the field. These results conclude that the integration of Google Sites and Wizer.me has great potential to serve as an alternative platform to support digital mathematics learning in schools.
