The type of research used is research and development (RD) with the ADDIE model. The ADDIE model consists of five stages of development, namely: Analysis, Design, Development, Implementation, and Evaluation. A total of 15 questions have been prepared covering the material for straight line equations, functions, coordinate systems, linear equations of two variables and number patterns in odd semesters. The items were validated by three mathematicians, and the calculations were analyzed using the Aiken index. Furthermore, the questions that were declared valid were tested on 34 students in two junior high schools in Makassar City using convenience sampling as a sample selection technique. The experimental data are dichotomous. The data were analyzed using KR-20 to produce a reliability coefficient. This study resulted in a HOTS-based numeric literacy test instrument in the form of multiple choice with a total of 15 valid and reliable questions. 15 items have high category validity, while the reliability coefficient of the item is 0.91, or high category.","PeriodicalId":33351,"journal":{"name":"Desimal","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135428813","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}

This research took place in Pematang Johar Village, Labuhan Deli District, Deli Serdang, North Sumatra. The type of research that the author examined was descriptive qualitative research, in which the collection of data was taken through a process of documentation, direct observation, and literature review. The documentation and observation are used to explore ethnomathematics and mathematical concepts in the Taman Sawah Tourism in Pematang Johar Village, while literature review is used to find out about the cultural values that exist in the Sawah Park Tourism in Pematang Johar Village. Based on the results of data collection, several mathematical concepts were obtained in the rice field garden tour, namely (1) Flat Shape Concept, (2) Line Concept, (3) Geometry Transformation Concept, (4) Set Concept. These tourist attractions can be used as a medium for learning mathematics, especially at the elementary and secondary levels, in order to increase interest in learning mathematics.","PeriodicalId":33351,"journal":{"name":"Desimal","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135801493","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}

MCA numeration is related to critical thinking skills. This study aims to describe the level of students' critical thinking skills in solving the MCA numeration questions. This type of research is descriptive-qualitative research. Data collection techniques in the form of written tests and interviews with test instruments are MCA numeration questions with four questions. The data analysis technique was carried out by giving tests, then interviewing the selected subjects to find out more about critical thinking skills, and then describing the results. The results showed that the level of critical thinking ability of class VIII students in solving MCA numeration questions in the number domain met the same criteria, namely the criteria of focus, reason, and situation. Domain algebra found that students have various levels of critical thinking skills with criteria that meet the criteria of focus and reason. In the geometry domain, it was found that students had a low ability to solve geometric problems, and in the uncertainty data domain, students only reached conclusions without giving reasons.","PeriodicalId":33351,"journal":{"name":"Desimal","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135801494","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}
