This research uses the descriptive qualitative type of research. The participants were three fifth-grade teachersfrom SD Negeri 6 Pitue, SD Negeri 13 Padang Lampe, and SD Negeri 20 Alesipitto. These schools were chosen because they were once the targets of the Kampus Mengajar Program, while one of the program’s activities was to assist in adapting technology in schools. The data collection used observation and interview techniques. The data analysis consists of data condensation, data presentation, and conclusion. The research results show that the teacher occasionally delivered geometry subject matter using technological devices such as a laptop and projector, as well as the Microsoft PowerPoint application. The use of technological devices and applications in learning was based on teachers’ consideration to make the lessons enjoyable and easy to understand by the students. The teachers also used WhatsApp social media to facilitate communication with students and parents. The obstacles to using technology in learning were the internet network which was not good enough and technological tools that were broken or even non-existent. The teachers’ consideration of the proper use of media in learning shows that teachers had good pedagogical and content knowledge, even though they had not optimally utilized technology. The TPACK of the teachers, especially in geometry, is still at the recognizing level.","PeriodicalId":446231,"journal":{"name":"JTMT: Journal Tadris Matematika","volume":"110 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138954086","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 samples used were students of class VIII.2 as the control class and students of class VIII.6 as the experimental class. The data collection process uses a questionnaire using a Likert scale, where the Likert scale is an ordinal scale, so the data analysis uses non-prametric statistics Mann Whitneyy U test. Based on data analysis with the Mann-Whitneyy U test, Asymp.Sig values are obtained (2- tailed) is 0.029. This significance value is less than 0.05 which results in H0 being rejected and H1 being accepted. So from this analysis it can be concluded that learning media based on Realistic Mathematics Education assisted by the pixton application is proven to be more affective in increasing students' interest in learning mathematics in SPLDV material compared to conventional learning.","PeriodicalId":446231,"journal":{"name":"JTMT: Journal Tadris Matematika","volume":"13 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138956008","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 population in this research were all grade VIII students of MTs Yasrib Limpomajang in the odd semester of the 2022/2023 academic year. The sampling method employed in this research is cluster random sampling. The instruments used for data collection were learning implementation observation sheets, student activity observation sheets, divergent thinking ability tests consisting of pretest and posttest. The data obtained were analyzed using descriptive and inferential statistical analysis. The results of descriptive statistical analysis indicate that before being taught using the Treffinger learning model, the average divergent thinking ability of students in the pretest was categorized as low. After undergoing learning with the Treffinger model, the average posttest divergent thinking ability increased to a good category. In conclusion, the Treffinger learning model contributes to the improvement of students' divergent thinking abilities in understanding numerical pattern material.","PeriodicalId":446231,"journal":{"name":"JTMT: Journal Tadris Matematika","volume":"8 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138603435","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 instruments in this study were reflective thinking ability test sheets, mathematical disposition questionnaires, and interview guidelines. The data analysis technique of this research uses the data analysis technique of Miles and Huberman. The results of the data analysis show that most students with high mathematical dispositions have high and moderate reflective thinking skills. Students with a high mathematical disposition have been able to fulfill the indicators of the reacting, elaborating, and contemplating phases well, although some are still constrained in the reacting phase. Students with a moderate mathematical disposition have moderate reflective thinking skills because they are still constrained in the reacting phase, but are able to fulfill the indicators in other phases well even though they are not systematic. Some students with low mathematical dispositions have not been able to meet the indicators in the reacting, elaborating, and contemplating phases, so their reflective thinking skills are also low.

This research is a qualitative research with an ethnographic approach whose stages include determining the scope, determining and interviewing informants, documenting and recording, domain analysis, taxonomic analysis and ethnographic writing. Based on the exploration results it is found that the observed customary equipment can be modeled into a relationship between polynomial functions, such as the relationship of two parallel lines and two perpendicular lines in the balli' and kanre anak, a quadratic function rotated about the x-axis represents the gandrang pannahan model. The  relationships of constant, linear and quadratic functions which are rotated about the y-axis produce the form of the gandrang jong. Furthermore, the concept of geometry can also be explored in the songkok recca as a sandan requirement whose surface is elliptical and the volume can be approximated using the concept of volume calculation using the slab approach.
