Abstract

This research aims to develop bilingual getrans teaching aids that can be used to visualise the concept of geometry transformation. The urgency of this research lies in the effort to facilitate students' understanding of abstract concepts in geometric transformations where the development of getrans teaching aids allows students to learn actively, involving physical and visual, which is believed to improve understanding and retention of concepts. Utilizing the 4D model, the Research and Development (R&D) approach is applied. The four phases of the 4D development model are defined, designed, developed, and disseminated. The findings showed that students had trouble grasping the idea of geometric transformation at the define stage. At the design stage, preparation for the development of bilingual getrans teaching aids was carried out. At the development stage, getrans props were made as well as validation of video results by experts and limited trials to students. Then at the dissemination stage, the revised video results were disseminated based on expert advice. The conclusion of this research is that bilingual getrans teaching aids can be used for learning mathematics which students can better understand changes in position, rotation, reflection, or dilation of objects in geometry with better.

Abstract

The development of this Google Sites-based interactive multimedia was motivated by the need for innovation in mathematics learning media that supports a student learning process that is engaging, interactive, and easily accessible. Observations in class X-2 and interviews with the mathematics teacher at SMA Negeri 2 Pekalongan revealed that instruction was conducted through a mix of online and offline modes. During mathematics lessons, some students struggled to grasp basic mathematical concepts, lacked the motivation to attempt problems independently, and tended to rely on Artificial Intelligence (AI) to complete assignments. Addressing these issues, this study aimed to develop a valid and practical Google Sites-based interactive multimedia tool to foster mathematical concept understanding among Grade X students at SMA Negeri 2 Pekalongan. The study employed the Research and Development (R&D) method using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The results indicated that the Google Sites-based interactive multimedia was highly valid, with a validity score of 91.339%, and highly practical, with a practicality score of 83.855%. Based on these findings, it can be concluded that Google Sites is suitable for use as a mathematics learning medium to develop students' understanding of mathematical concepts.
