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.

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.

ABSTRAK A. PENDAHULUANDalam peraturan Menteri Pendidikan Nasional Nomor 20 Tahun 2006 mengatur tentang Standar Isi, bahwa pembelajaran matematika bertujuan supaya siswa memiliki kemampuan penalaran tinggi melalui latihan memecahkan masalah, membuat keputusan dan kesimpulan. Harapannya, pembelajaran seperti ini membuat siswa terlatih untuk berpikir kritis dalam menyelesaikan persoalan-persoalan tersebut. Pembelajaran matematika yang baik diharapkan siswa akan dapat memiliki kemampuan berpikir logis, analitis, sistematis, kritis, kreatif dan kemampuan untuk bekerjasama secara efektif sesuai dengan yang tercantum dalam Kurikulum 2013Kurikulum (permendigbud, 2013. Kurikulum 2013 merupakan program pemerintah di bidang pendidikan yang

The purpose of this research was to develop a valid, practice and effective a bilingual scientific-worksheet of the indefinite integrals. This research is development research with 1) Preliminary investigation phase, 2) Prototyping phase, 3) Assessment phase. Data were collected from test and questionnaire and analyzed to examine validity, practicality, and effectiveness the worksheet. The result of this research was producing bilingual scientific-worksheet of indefinite integral materials that oriented for learning achievement improvement. The validity obtained content, language, and illustration from expert judgment. The practicality was on the relation, attention, belief, and student satisfaction. The effectiveness based on the result of achievement test on indefinite integral.

Algebra is essential to learning mathematics and as a basis to support another mathematical concept. On the other hand, students have not fully mastered the concept of algebra which causes errors in solving problems. This qualitative research aims to describe students' misconceptions in solving algebraic questions based on the Newman method to understand mathematical concepts. The data were taken from six eighth-grade students at SMP N 1 Turi consisting of high, medium, and low abilities. The results of the analysis showed that the students did not make reading errors. Meanwhile, the misunderstanding of the question's students did not write down the information in the questions. It was because students were not used to writing what was known and asked in the questions. Students do not write down the strategies used, so that transformation errors are found. Errors in student process skills do not complete. The cause of this is an error in determining information on the questions and difficulties in solving them. The mistakes made by students in writing the final answer were not reporting the units and conclusions from the results of the solutions.
