This study aims to produce student worksheets based on geogebra-assisted guided discovery on the material of flat-sided shapes that are valid, practical, and effective. This research is a research on the development of Dick and Carry with 5 stages, namely the stages of Analysis, Design, Development, Implementation, and Evaluation.Valid products are seen from the results of expert validation, practical products are seen from the results of the questionnaire, while effective products are seen from the results of trials. The results of the validation of the experts obtained that the material aspect was declared very valid with a result of 90.59%, while the media aspect was declared very valid with a result of 98.00%. The results of the teacher response questionnaire obtained results of 90.59%, while the results of the student response questionnaires were 93.37% with very practical criteria. The trial results obtained results of 80% with effective criteria where there were 8 students who passed and 2 students who did not complete the minimum passing standard determined by the school was greater than or equal to 70 for mathematics subjects, It can be concluded that geogebra-assisted discovery-based student worksheets are used with very valid criteria, very practical and effective.

This study aims to explore mathematical objects in the Balale’ tradition of the Dayak Salako tribe in Nyarumkop Village and then integrate them into the Creation of Culture-Based Modules. The research method used is the ethnographic method, and the type of research used is qualitative. The Balale’ tradition is one of the habits of the Nyarumkop farmers when working the rice fields collectively and in rotation. The Balale’ tradition aims to strengthen relations between communities, because the community works together in the fields to complete tasks such as clearing land, planting rice, clearing grass, and harvesting rice. The results of the study show that the Balale’ tradition has a direct mathematical object in the form of facts that lie in the people who join the lale’an members, the concept lies in the process of working the rice fields which are carried out in turns, the principle lies in the mindset of the community in carrying it out and the skills lies in the work technique of each member of Lale’an. This research also contains indirect mathematical objects in the form of discipline shown by Lale’an members in carrying out this tradition. Then it is mathematically integrated into the creation of a culture-based SPLDV Module using mathematical concepts.

This study aims to produce powtoon-based learning video learning media to improve students' critical thinking skills in class VIII two-variable linear equation system (SPLDV) material at SMPN 2 Putussibau which achieves a level of validity, practicality, and efficiency. This research method uses research and development involving 3 material validator experts and 3 media validator experts. The subjects of this study were grade VIII students of SMPN 2 Putussibau totaling 14 students. Data collected validation sheets, student response questionnaires, teacher response questionnaires, and tests of students' critical thinking skills. The results of this study showed that the learning video media assessed validity 86% (very valid), practical assessment 84% (very practical) and effectiveness assessment 85.7% (very effective). So, it can be stated that animated videos are suitable to be used as learning media for grade VIII SMPN 2 Putussibau regarding the subject of Two Variable Linear Equation System (SPLDV).

The purpose of this study was to describe students' mathematical literacy abilities based on the level of mathematical connection ability using a qualitative descriptive approach. The researcher as the main instrument was assisted by test questions to measure the ability to connect mathematics and mathematical literacy, as well as interviews. The research subjects were 3 class IX students of SMP Islam Pakis. Subject selection was made based on high, medium, and low levels of mathematical connection ability. The results showed: The selection of research subjects was carried out by purposive sampling technique based on high, medium, and low levels of mathematical connection ability. The results of the data analysis obtained: (1) students at a high level of mathematical connection succeeded in achieving all indicators of mathematical literacy ability, such as being able to identify the information contained in the problem, make mathematical models, do reasoning, use symbols, design and implement appropriate problem strategies, summarizing the results, as well as conducting evaluations; (2) students who are categorized in the moderate level of mathematical connection ability are able to achieve five of the seven indicator components contained in mathematical literacy ability; (3) students who belong to a low level of mathematical connection ability are only able to achieve three of the seven indicator components needed in literacy skills.
