Abstract

The curriculum in Indonesia has gone through various changes which are expected to make education in Indonesia grow and educate the nation's children. Government developing a Merdeka Curriculum. The Merdeka Curriculum gives students the freedom to seek scientific information so that it fosters activeness in students in learning. The purpose of this research is to know and describe the steps to overcome students when learning mathematics. This Type of research is qualitative research using descriptive methods. This research was conducted at senior high school in Surakarta with the research subjects being students of class E4 at senior high school in Surakarta and having the research objective of knowing and describing things that make students active and inactive which make students during Mathematics Learning. Furthermore, the method of collecting data in this study is observation, interviews, and giving appointments to students. Analysis conducted by researchers namely data collection, analysis of data obtained, drawing conclusions. The results of this study are the activeness of students supported by the division of small groups to build student activity in the classroom. The enthusiasm of educators can build student activity such as giving games before learning takes place. Educators also deliver material in an interesting way to make students active to learn in the classroom.

Abstract

This study aims to determine (1) The extent of the tendency of students' interest in learning mathematics online. (2) To what extent the tendency of students' interest in learning mathematics towards the use of Zoom Meeting and Google Classroom. This research is a descriptive research with a qualitative approach. The research was conducted at SMP Kanisius Sumber Dukun with a sample of 30 students selected using Purposive Sampling technique. Data collection techniques using observation, interviews, questionnaires, and documentation. The research instruments used were interview guidelines and interest questionnaires. While data analysis techniques using data triangulation include data reduction, data presentation and conclusion drawing. The results of this study indicate that (1) The tendency of students' interest in learning mathematics online is included in the high category with a percentage of 72.01%. (2) The tendency of students' interest in learning mathematics whose learning uses Zoom Meeting is included in the very high category with a percentage of 77.42%, while the learning interest of students whose learning uses Google Classroom is included in the very low category with a percentage of 22.58%. This means that the tendency of mathematics learning interest of Kanisius Sumber Junior High School students towards the use of Zoom Meeting is higher than Google Classroom.

Abstract

The present study is motivated by the issue of low interest in mathematics among students in private elementary schools in Jakarta. Despite the abundant resources and infrastructure that support learning, technology has not been fully utilized to enhance students' engagement with mathematics. Consequently, students' learning interest has been declining, which in turn negatively impacts their enthusiasm and passion for learning. The aim of this study is to investigate how the application of educational games can increase the learning interest of elementary school students in mathematics, using a descriptive qualitative method. Educational games offer a convenient and effective means for teachers to deliver material, as they create an active, enthusiastic, and enjoyable learning environment in the classroom. The combination of technology and the role of the teacher is essential in supporting students' learning and developing human resources. By integrating educational games into the curriculum, students' interest and attraction in learning mathematics can be enhanced, making educational games an effective tool for increasing students' learning interest. Based on the findings of this study, the researcher suggests the importance of developing educational games and digital teaching materials, as well as moving away from conventional teaching methods. These recommendations are essential for enhancing students' learning interest and promoting effective learning in the classroom.

Abstract

The purpose of this study was to analyze publications on differentiated learning and mathematical creative thinking in order to increase aligned referrals. Data collection techniques used PoP (Harzing) software, while data analysis utilized VOS Viewer software. A total of 200 articles on differentiated learning and mathematical creative thinking were retrieved from Google Scholar data sources from 2013 to 2023 and were analyzed using a bibliometric analysis approach. The bibliometric analysis included sources, authors, and accuracy derived from the keywords "differentiated learning and mathematical creative thinking," which were analyzed by the author and illustrated using the VOS Viewer software. Based on the study's results, it was found that there is a relationship between the term "differentiated" and the words "creative thinking, curriculum, teachers, and public junior high schools." Furthermore, the term "differentiated" is widely used in research on "differentiated learning," including differentiation and its relation to creative thinking. This research was widely conducted in 2018-2019. Additionally, many other researchers have carried out research on differentiation in differentiating learning. Future researchers can choose data sources other than Google Scholar in PoP (Harzing) software during data collection to enhance this research in increasing aligned references regarding differentiated learning and mathematical creative thinking.

Abstract

The low independence of student learning, especially in mathematics lessons, is a driver for research. Based on observations, most students do not realize the importance of learning independence. Many students don't want to learn math, and most don't like it because they think math is too difficult. Survey methods with simple regression analysis are used in research. The study aims to determine the effect of independence on mathematics learning achievement of seventh grade students at State Junior High School 7 Bekasi City in the even semester of the 2022/2023 academic year. Sampling using a simple random sampling technique with 38 students from seventh grade at Junior High School 7 Bekasi City. Data analysis using the help of the Statistical Program for Social Science (SPSS) 22 program with stages of descriptive statistical analysis, testing prerequisites for data analysis (normality test, linearity test, and hypothesis test). The results of the study can be concluded that there is an influence of independence on mathematics learning achievement in seventh grade of junior high school students. The effect of independence on students' mathematics learning achievement was 10.4%, and 89.6% was influenced by other factors.

Abstract

The lack of information about designing buildings, measuring, patterning and calculating from ancient people, makes the concept of mathematics applied by people in the past remains unknown. It is necessary to study mathematics from a cultural point of view of society. This study is carried out through a cultural approach, or what is commonly referred to as ethnomathematics. Mathematics that is used by recognized cultural groups, such as national communities, ethnic groups, labor organizations, children of particular age groups, and professional classes, is known as ethnomathematics. Finding the mathematical principles used to construct the Gedong Songo Temple in Candi Village, Bandungan, Semarang Regency, Central Java, is the goal of this study. The object of research in this case is the Gedong Songo Temple. The approach taken is a qualitative one. In this study, an ethnographic technique was used. Data collection is done by literature study and observation. This research is structured descriptively, starting from reviewing problems related to ethnomathematics, formulating problems, collecting theories, analyzing, discussing data, and making conclusions. The findings demonstrated that geometry, symmetry, periodic patterns, and ratios are among the mathematical concepts used in the construction of the Gedong Songo Temple. The findings of this study can be used to improve mathematics instruction in cultural contexts. In addition, further studies on ethnomathematics can be carried out to see more comprehensively the mathematical concepts applied to the structure of the temple building.
