Abstract

Penelitian ini bertujuan untuk mengetahui efektivitas model PMRI dengan model pembelajaran kooperatif untuk peningkatan keterampilan berfikir matematis siswa. Melalui pembelajaran matematika, siswa diharapkan memiliki kemampuan berfikir logis,  analitis, sistematis, kritis, dan kreatif, serta memiliki kemampuan bekerjasama. PMRI adalah model pembelajaran yang bertitik tolah dari hal-hal yang real bagi siswa, menekankan keterampilan “proses of doing mathematics”. Penelitian ini merupakan penelitian jenis penelitian Quasi-Experimental, dimana kelas kontrol diberikan perlakuan pembelajaran matematika melalui model kooperatif, sedangkan kelas eksperimen diberikan perlakuan model PMRI. Berdasarkan Muhammadiyah 3 Yogyakarta untuk rata-rata nilai post test berfikir matematis kelompok eksperimen adalah 83.22 sedangkan untuk kelompok kontrol 58.58. Sedangkan di SMP Negeri 16 Yogyakarta nilai post test berfikir matematis kelas eksperimen sebesar 75.65, dan kelas kontrol 54.45. Berdasarkan hasil uji hipotesis perbedaan kemampuan berfikir kritis menggunakan uji t (independent samples T-Test) diperoleh nilai signifikan 0,000 dengan taraf signifikan 2%, diperoleh kesimpulan Ho ditolak, sehingga terdapat hasil perbedaan antara kelompok eksperimen setelah dikenakan Model PMRI. Berdasarkan uji pengaruh model pembelajaran masing-masing diperoleh t hitung di SMP Muhammadiyah 3 Yogyakarta 0,292 dan SMP Negeri 3 Yogyakarta 0,346 dimana semua nikai tersebut lebih besar dari t tabel, sehingga Ho dengan hipotesis terdapat pengaruh model PMRI terhadap peningkatan kemampuan berfikir matematis.Kata kunci: Model Kooperatif, Model PMRI, Kemampuan Berfikir Matematis

Abstract

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.

Abstract

Multiplication is the most difficult basic arithmetic operation and has been documented since 1980. Another multiplication difficulty dealing with story problems, they tend to assume that multiplication produces a larger result and the other way for division. Several studies show basic mathematics as one of the cognitive factors that affect the financial literacy ability of each individual. This study used a qualitative descriptive analysis with the subject of three students from different schools and geographical locations. Basic mathematics as one of the cognitive factors that affect the financial literacy ability of each individual The introduction of cases such as ordering through online applications in learning mathematics may improve students' knowledge about activities related to finance. Individual context is important in personal financial management since the decision pertains to the fulfilment of personal needs.

Abstract

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.

Abstract

Financial literacy is a knowledge and attitude about finance and is a 21st-century skill. As a knowledge, a cognitive factor of a person will impact their financial literacy skill. Through a bibliometric analysis study of 274 documents published from 1994 to 2022 in the Scopus database, we found that mathematics literacy is the cognitive factor of one's financial literacy skill. The OECD and several studies offer intertwined concepts, financial literacy and mathematics, to be presented in the mathematics curriculum in primary and secondary schools. After we got the bibliometric results, we surveyed several junior high schools in Yogyakarta to learn more about this issue. A total of 15 mathematics teachers participated in this survey, randomly chosen in junior high school. We got information stating that mathematics teachers used financial terms as a social arithmetic context, did not teach financial knowledge and attitudes, and never heard 13 from 17 financial terms in the survey. Furthermore, we present a framework for implementing financial literacy in mathematics through three dimensions, content, context, and process. The dimension content consists of mathematics' and financial content. On the other hand, the dimension context is related to education and work, home and family, and individual and societal. As a cognitive process, the dimensions of the process are based on Bloom's Cognitive stages. The potential for future research is developing learning activities and implementing them in the independent curriculum, which impacts schools' ability to use project-based learning, which is the most approach to implementing financial literacy in mathematics classes.
