Before And After

Learning mathematics is not only aimed at developing mathematical cognitive abilities, but also for developing affective domains. One important aspect in the affective domain that is very influential and determines success in learning mathematics is the positive view of students on mathematics or in mathematics learning called mathematical disposition. A student who has a high disposition will be more persistent and resilient in facing mathematical problems that are more challenging and will be more responsible for their own learning and always develop good habits in mathematics. The problem posing approach which in the learning process requires students to ask questions and make their solutions is expected to be able to change students 'views of mathematics to be more positive, while also improving students' mathematical abilities. This study aims to examine the differences in the levels of mathematical disposition of junior high school students before and after learning through the problem posing approach. The type of research is experimental research with the design of one group pre-test post-test design. The population in this study were all VII grade students of Bandar Baru 1 Junior High School, with research samples of class VII2 students selected through random sampling techniques. The instrument used to obtain the research data was a mathematical disposition scale questionnaire sheet. The statistical test used to analyze data on differences in mathematical disposition of junior high school students before and after learning through the problem posing approach is paired t-test. The results showed that there were significant differences in the level of mathematical disposition of junior high school students before and after learning through the problem posing approach. This means that students' mathematical dispositions get better after they get a problem posing learning approach. Keywords: Mathematical Disposition, Problem Posing Approach

Purpose: Research has confirmed that students’ mathematics values significantly affect their mathematics learning. Accordingly, understanding how students’ values form and change, especially during different learning stages, is an important topic. Design/Approach/Methods: This study administered a questionnaire to investigate the values of primary, junior high, and senior high school students in Eastern China. A principal component analysis was conducted to investigate the factor structure of the students’ learning values. Then, paired sample t-tests were used to examine the differences in the two continuous categories ranking of each group, and a one-way analysis of variance with a Brown–Forsythe test was used to test the differences in the ranking of each dimension by the different grade-level groups. Findings: We found that students’ mathematics learning values consist of seven elements: culture, memorization, technology, objectism, practice, understanding, and control. Students placed different degrees of importance on these seven elements at different learning stages. Additionally, we found that junior high school is a critical period of change in students’ values. Originality/Value: These findings will be invaluable to teachers and educators as they reflect on their teaching approaches. Moreover, the findings that students’ values undergo changes in the course of their schooling are important information for educators seeking to foster students’ learning.

Abstrak: Penelitian ini bertujuan untuk menghasilkan soal matematika model TIMSS yang valid dan praktis untuk siswa SMP berdasarkan Kurikulum 2013. Metode penelitian yang digunakan adalah penelitian pengembangan. Proses pendesainan soal sebagai instrumen penilaian dilakukan dengan prototyping. Prototyping meliputi dua tahap. Prototipe I merupakan hasil desain dan penyusunan soal-soal oleh peneliti sendiri, sedang prototipe II revisi dari prototipe I berdasarkan masukan dari pakar, teman sejawat, dan guru matematika, yang berupa catatan validator dan notulensi diskusi. Hasil penelitian menunjukkan bahwa buku soal yang disusun dengan pengelompokan bab mengikuti ranah materi seperti dalam TIMSS, yakni bilangan, geometri, aljabar, data dan peluang. Buku soal untuk siswa tidak perlu ada tulisan mengenai ranah materi, topik pokok, dan ranah kognitif. Masukan untuk perbaikan dari FGD adalah soal sebaiknya diawali dari yang mudah, sedang, baru yang sulit. Penulisan soal pilihan ganda lebih baik tidak menggunakan kalimat tanya, melainkan dengan membuat pernyataan yang memuat titik-titik, baik di tengah atau di akhir kalimat. Soal sebaiknya tidak memuat pernyataan implikasi.

The study used the research and development design. The design process of the problems as assessment instruments was carried out through prototyping involving two stages. Prototype I was the design product and the problem development done by the researchers themselves, while Prototype II was the revision of Prototype I based on the feedback provided by experts, colleagues, and Mathematics teachers in the form of validators’ notes and the minutes taken from discussions. The findings showed that the book of math problems was written by grouping the chapters following the materials domains as those in TIMSS, that is, numbers, geometry, algebra, data, and probability. For the student book, it was not nsecessary to write the materials domain, the essential topics, and the cognitive domain. The feedback from the FGD was that the problems should be arranged from the easiest ones to the most difficult ones. The multiple choice items should not be written in the form of questions, but in the form of incomplete sentences with the blanks in the middle or the end of the sentences. The items should not ask about implication. Keywords: Development of problems, junior high school mathematics, TIMSS, Curriculum 2013
