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 low ability of students in solving non-routine problems highlights the importance of examining their mathematical problem-solving abilities in contextual circle problems. Problem-solving ability refers to how individuals utilize their knowledge and skills to handle unfamiliar situations. These abilities are analyzed based on five indicators proposed by Krulik and Rudnick: read and think, explore and plan, select a strategy, find an answer, and reflect and extend. This study employed a descriptive qualitative method with data collected through written tests and semi-structured interviews. Data were analyzed using the Miles and Huberman model. The test instrument consisted of three contextual circle problems with different levels of guidance: complete guidance, brief guidance, and no guidance. The results show that students’ problem-solving abilities varied across each problem. In the first problem, most students from all categories were able to complete the task according to the indicators, although errors occurred in the calculation and reflection stages. In the second problem, one student in the moderate category showed a decline from the planning to the reflection stage, while students in the low category experienced a more significant drop. In the third problem, only students in the high category consistently showed good abilities, while moderate and low-category students struggled in nearly all stages. One student in the low category even made no attempt to solve the problem. Students’ problem-solving profiles are reflected through their successes and obstacles in carrying out the five problem-solving stages.
