The research was carried out in the even semester of the 2020/2021 academic year at SMP Negeri 3 Kendari. The results show that the experience of ethnomathematics has a significant effect on understanding the concept of numbers by 0.302. Meanwhile, differences in  characteristics have no effect on students' understanding of the concept of numbers at SMP Negeri 3 Kendari. This result explains that if students' ethnomathematical experience increases by one unit, then students' knowledge of mathematical concepts will increase by 0.302 units. Ethnomathematics experience can be used to design mathematics learning in an ethnomathematical context based on local wisdom in the classroom. Teachers can consider using ethnomathematical contexts based on students' experiences with traditional games they know and have played to create a condition for learning mathematics that is fun and easier to understand because it is close to students' daily lives and contains cultural values ​​that can shape students' character.","PeriodicalId":52842,"journal":{"name":"Jurnal Tadris Matematika","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49175960","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 purpose of this study is to describe the way pottery crafters construct curved-sided spaces and reveal the concept of curved-sided spaces found in pottery making in Banyumulek Village. This type of research is descriptive qualitative research. The subjects in this study were two pottery artisans who were selected using purposive sampling technique. The research subjects were chosen based on certain considerations, namely the subject is a practitioner or expert in making pottery. The data collection techniques used were interviews, observation, and documentation. The results showed that the way pottery craftsmen construct the curved side space in pottery making consists of 4 processes, namely, making tombong (base), bebentet (curved side), belong (neck or connecting curve), and making biwir (mouth or lid) pottery. In addition, there is a concept of curved-sided space in pottery making in Banyumulek Village, namely the concept of partial tubes, cones, spheres, and the concept of whole tubes.","PeriodicalId":52842,"journal":{"name":"Jurnal Tadris Matematika","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47832674","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 results of the interviews show that students have difficulty understanding the material when learning is done online. For this reason, a qualitative descriptive study was carried out which aimed to analyze and describe students' conceptual understanding abilities in solving matrix problems using the APOS stages. The research subjects were 3 students of the informatics engineering study program who had taken computational mathematics courses and received matrix material, were in the category of students with low, medium, and high conceptual understanding, and were able to communicate their thoughts orally and in writing. Data collection techniques were carried out through written tests, interviews, and observations. The results showed that students with low conceptual understanding were able to solve matrix problems up to the object stage and made calculation mistakes. Students with a moderate understanding of concepts can solve matrix problems up to the schematic stage but are not careful in doing calculations. Meanwhile, students with high conceptual understanding can solve matrix questions up to the schematic stage, determine the correct answer, make conclusions, and reflect on the problem-solving obtained.","PeriodicalId":52842,"journal":{"name":"Jurnal Tadris Matematika","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46969525","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}
