KEMAMPUAN BERPIKIR KRITIS MATEMATIS SISWA DALAM MENYELESAIKAN SOAL KEKONGRUENAN DITINJAU DARI SELF CONFIDENCE

Mustofa Ali — 2024-08-27

This study aims to describe students' mathematical critical thinking skills in solving congruence problems based on students' self-confidence. The research method used is descriptive qualitative analysis with data collection using tests, questionnaires and interviews. The research was conducted on 23 students of class XII IPA MA Al-Khoirot. The research subjects were selected three students based on self confidence, namely high, medium and low. The results obtained data that students with high Self-Confidence level can fulfill four indicators of mathematical critical thinking ability, while students with moderate Self-Confidence level can fulfill two indicators of mathematical critical thinking ability and students with low Self-Confidence can only fulfill 1 indicator of mathematical critical thinking ability. In this case, it means that students' mathematical critical thinking patterns are connected to their self-confidence, the higher the level of self-confidence that students have, the higher the level of mathematical critical thinking.

Keywords: mathematical critical thinking, mathematics education, self-confidence

Inayah Dzil Izzati Hartono — 2024-08-27

One that bridges education and culture, especially mathematics education, is ethnomathematics. The nature of mathematics tends to be linear and rigid but when integrated with something soft like culture, it becomes flexible. This research explores ethnomathematics activities on the traditional wedding clothes of the Bugis tribe which have various components that illustrate several mathematical concepts. This research uses qualitative research with an ethnographic approach to investigate and obtain an in-depth description and analysis of a cultural group based on fieldwork in a certain period of time intensively. Determination of the subject of this study using purposive sampling technique, namely sampling with certain considerations. The results showed that baju bodo includes several ethnomathematics activities including counting activities on baju bodo and its accessories found to have an odd number of components, measuring activities with the size used in baju bodo components such as clothes, sarongs, arm bands and waist bands using non-standard units, namely cubits or equal to the size of one adult's palm, design activities by paying attention to the shape of each component as well as patterns on the clothes found the shape of the pattern and geometric design motifs that dominate some components of the bodo clothes and on the subordinate cloth of the bodo clothes have a plaid motif that is symmetrical flat shapes, and the activity of explaining the local meaning of each component of the bodo clothes in terms of how it is measured, the odd number of components, the reason for the shape and color of each component of the bodo clothes. This study shows several ethnomathematics activities contained in the components of the bodo shirt including counting activities, measuring activities, designing activities and explaining activities.

PEMBELAJARAN MATEMATIKA MENYENANGKAN DALAM MENINGKATKAN KEMAMPUAN LITERASI DAN NUMERASI DI SDN 05 ANTAN RAYAN

Brian Febrianto Atrensius Tiko — 2024-08-27

Literacy and numeracy are very important basic skills for every student that can be useful for everyday life. Based on the research results, it is known that the literacy and numeracy competencies of students in Indonesia are still very low. Therefore, the Ministry of Education and Culture (Ministry of Education, Culture, Research and Technology) through the independent campus learning policy (MBKM) created a program, namely the teaching campus, which teaches students to contribute to efforts to improve the literacy and numeracy learning of students in Indonesia, especially for elementary school, junior high school and vocational high school students. Teaching campus students are assigned directly to the schools where they live and whose literacy and numeracy skills are still low according to data from the local education office to help the school, become teacher partners and collaborate with teachers at the assigned school and help the participants. students according to school conditions and students' needs. Apart from that, teaching campus students also guide grade 5 (five) students in implementing the student AKM to measure the extent of students' literacy and numeracy abilities. The aim of this teaching campus is so that students can collaborate with teachers at assigned schools, students can study outside the campus environment and be directly involved in seeing conditions at the school and helping students improve literacy and numeracy as well as adapting to technology.
