However, mathematics for most students, mathematics is one of the most feared and difficult subjects to understand due to a lack of understanding of the concepts needed. In line with the mathematical concepts needed in learning, a teacher can associate mathematical concepts with local culture. Mathematics found in culture is called ethnomathematics. This study explores the mathematical concepts of Gotong and Bulang. Gotong and Bulang are part of the Simalungun traditional clothing which functions as a head cover for married men and women. This study aims to explore various mathematical concepts contained in Gotong and Bulang Simalungun. The research method used is a qualitative method with an ethnographic approach. Data collection was carried out through observation, interviews, documentation, and literature study. The data collection instruments used were observation sheets, interview sheets, cameras, field notes and voice recorders. Data analysis techniques include data reduction, data presentation, and drawing conclusions. The results obtained from this study indicate that there are mathematical concepts in Gotong and Bulang, namely the concept of numbers, parallel lines, folding symmetry, triangular plane shapes, and transformation geometry. Thus, it can be concluded that Gotong and Bulang Simalungun can be used as tools for learning mathematics that are concrete in understanding mathematical concepts.","PeriodicalId":472125,"journal":{"name":"EMTEKA Jurnal Pendidikan Matematika","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134949600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The level of anxiety can be seen from the students' responses in solving math problems. The process of minimizing these conditions in order to obtain better learning outcomes requires learning techniques that are in accordance with students' cognitive abilities. The learning technique that corresponds to this is the scaffolding technique. This study aims to analyze the factors that cause learning difficulties in mathematics in terms of math anxiety in the opportunity material for class X SMAN 2 Seunuddon and the results of applying scaffolding techniques to overcome the level of anxiety. The research approach is in the form of a qualitative descriptive type. X-2 grade students' research subjects. Data collection techniques used observation, tests, questionnaires, and interviews which were then analyzed using reduction, presentation and conclusion of data. Based on the test results, it was found that the difficulty of learning facts, concepts, operations and principles was 58%, 50%, 58% and 75%, respectively. Through interviews, it was found that the factors that caused students to experience learning difficulties were: difficulties in understanding the opportunity material, there were physical disturbances to students, lack of interest in studying mathematics, lack of self-motivation, teachers were less interesting in presenting material, lack of motivation from parents and inadequate facilities. Next, the scaffolding technique of the environmental provisions type was carried out. The test results after the technique was carried out found difficulty learning facts, concepts, operations and principles of 8%, 8%, 8% and 41%, respectively. Thus it was concluded that the use of scaffolding techniques of the environmental provisions type provided a significant reduction in students' difficulties caused by anxiety in working on word problems on probability material.","PeriodicalId":472125,"journal":{"name":"EMTEKA Jurnal Pendidikan Matematika","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134969899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
