This study was motivated by student errors in trigonometry. This study aimed to describe the types of student errors in solving trigonometry problems using the Newman error analysis procedure. This research is descriptive qualitative with the subjects of vocational high school students. Data collection involved written tests, depth interviews, and documentation. The results show that most students made comprehension and transformation errors. The comprehension errors consisted of not writing down what was known and asked; immediately writing down the completion process with the wrong formula and incorrect understanding of the concept of the basic trigonometric formula. The transformation errors were not being able to transform information on the problem into the mathematical model, and incorrect in mentioning the formula.

Some of the android-based mobile game genres that are currently very popular such as adventure, first-person shooter, fighting, racing, and others. This development should provide opportunities in the field of education to make games not only for fun but also for education. The purpose of this study was to produce educational games that were valid, practical, and had potential effects to improve the mathematical understanding of the relationship and function of junior high school students. The research method used is RD (research development) using the ADDIE model. The data collection techniques used were documentation, interviews, and tests of mathematical comprehension abilities. The results obtained from the game "The Incredible Boong Gi" are valid with an average of 96.70% of expert validators and media validators. The results of the practicality questionnaire from 9 students averaged 90.32%. The results of data analysis show that educational RPG games have valid, practical criteria and have potential effects. RPG games are valid in terms of relevance, systematics, student-centered compatibility, game design, and compatibility. RPG games get practical results from implementation in small groups. Furthermore, the educational RPG prototype has the potential effect of improving students' mathematical understanding abilities. RPG games provide a fun learning atmosphere, by playing students can also learn. Making RPG games is also not difficult, according to the competence of students to be achieved and challenges the creativity of the teacher.

Freudenthal's ideas on mathematics that stated mathematics as a human activity and mathematics must be connected to reality have colored towards learning mathematics all over the world, including Indonesia. Existing research on this topic in Indonesia among two decades is categorized and compared. This paper presents a systematic literature review of empirical studies on this learning approach in Indonesian context. The implementation of this approach in Indonesia was analyzed comprehensively and divided into several major topics. Resources of this research come from 110 articles by ten highest rank accredited journals by the Ministry of Research, Technology, and Higher Education, the Republic of Indonesia as an achievement for the peer-reviewed journal, which has excellent quality in management and publication. The results show that there are seven categories summarized in this research: the dominance of published RME articles, RME research subjects, mathematical topics, students' abilities, RME terms, and the research method used in RME articles. Lastly, the summarized 110 papers are displayed in the table to give essential information as a fundamental idea for further RME research.

The Industrial Revolution 4.0 on Education in Indonesia affects school activities rapidly. Teachers are no longer educated in classrooms only, but they can also utilize technology to conduct distance learning. One interactive application that can be used as a form of question exercise is Quizizz. Therefore, this research aims to: first, examine the effectiveness of students' activities by using Quizizz on mathematical problem-solving skills; second, investigate the differences in the increase in students' ability to solve mathematical problems between the class with and without the Quizizz-aided learning method; third, describe the activities of students who used the Quizizz-aided drill learning method; and fourth, describe the students' responses in using Quizizz. The research was quasi-experiment with a pretest-posttest non-equivalent control group design. The participants in this study are 67 of Grade10 students divided into experimental and control classes. Data collection techniques used were tests for students' mathematical problem-solving skills and questionnaires. The instruments were validated using Pearson correlation, while the reliability was tested using Cronbach's Alpha. Then, the N-gain test was used to analyze the data. The results showed that there was an effect on students’ learning activities by using Quizizz on their problem-solving skills. Besides, there was a difference in the improvement of problem-solving skills between the class with and without Quizizz-aided. Furthermore, students’ activities in three meetings have increased. Moreover, students provided a positive response in learning using Quizizz. Thus, it can be concluded that Quizizz is effective in improving mathematical problem-solving skills.

Penelitian ini bertujuan untuk mendeskripsikan kemampuan representasi matematika siswa berdasarkan kemampuan siswa. Subjek penelitian adalah tiga siswa kelas 5 SD di Sampangan, Yogyakarta, Indonesia. Mereka dipilih dari 30 siswa yang memiliki kemampuan tinggi, sedang, dan rendah. Hasil penelitian menunjukkan bahwa bahwa siswa dengan kemampuan tinggi mampu menggunakan representasi visual, simbolik dan verbal. Siswa dengan kemampuan sedang mampu menggunakan representasi visual dan simbolik namun kurang mampu menggunakan representasi verbal. Siswa yang berkemampuan rendah, tidak mampu menggunakan representasi baik dalam bentuk visual, simbolik maupun verbal. Kemampuan melakukan representasi verbal disebabkan karena representasi ini jarang digunakan dalam proses pembelajaran
