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. Kata kunci: Pengembangan soal, matematika SMP, TIMSS, Kurikulum 2013DEVELOPING THE TIMSS MATH PROBLEM MODEL TO SUPPORT THE MATHEMATICS LEARNING IN GRADE VII USING THE 2013 CURRICULUM Abstract: This study was aimed to produce a valid and practical TIMMS math problem model for junior high school students using the 2013 curriculum. 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

Research Highlights The study proposed two focus studies and results indicated there is a conformity between Brain Based Learning (BBL) and students' intrapersonal intelligence toward characteristics of junior high school mathematics learning. Implementation of Brain Based Learning (BBL) and intrapersonal intelligence in junior high school mathematics learning can improve student’s learning outcomes.   Research Objectives This research aims to knowing activities of junior high school mathematics learning and to knowing conformity of characteristics between Brain Based Learning (BBL) and intrapersonal intelligence with junior high school mathematics learning. BBL as a learning strategies and intrapersonal intelligence as an internal factors of students must be the main consideration in learning activities, including in this case mathematics learning. Learning is more directed at construction than instruction, which has implications for the role of teachers and students (Reigeluth and Carr-Chellman, 2009). Learning strategies concept is a various types of plans used by the teacher to achieve goals (Silver et al., 2012). In simple terms, this view states that learning strategies are ways to do something in achieving goals. Learning mathematics is learning about the concepts and structure of mathematics and looking for relationships between the two on the material being studied (Bruner, 2009). In the learning activities, learning materials must be adapted to the abilities and cognitive structures of students. Learning material must be related to the concepts that are already owned so that new ideas can be fully absorbed by students (Ausubel, 2012). Learning activities must be gradual, sequential and always based on past learning experiences.   Methodology This type of research is qualitative descriptive. The approach used is qualitative with descriptive methods and literature studies. Data collection uses documentation studies, observations, and interviews with teachers and students. Data collection was conducted in junior high school of SMP Assahil Lampung Timur in the 2018/2019 academic year. The mathematics teachers and students were included in this study as a respondents. In this study the data analysis used was quantitative descriptive and qualitative descriptive analysis. Quantitative descriptive analysis is used to present and analyze data relating to mathematics learning outcomes over the past three years. Qualitative descriptive analysis is used to interpret and analyze data regarding the learning process of mathematics that has taken place.   Results The study indicate that mathematics teachers have only used expository learning strategies in learning activities. The expository learning strategy is a form of teacher-centered learning approach. Mathematical learning outcomes are not satisfactory. The Mathematics learning is a learning process that involves active students building mathematical knowledge (Cobb, 2013). In mathematics learning there is a process of developing students' creativity to improve their abilities and beliefs in building knowledge and mastering good mathematics subject matter. The Characteristics of Brain Based Learning (BBL) emphasizes students to play an active role in building the concepts learned (Ulger, 2018). The steps in the BBL learning strategy include creating a learning environment that challenges students' thinking skills (regulated immersion), creates a relaxed learning environment, and creates actual and meaningful learning situations for students (active processing). Intrapersonal intelligence is self-knowledge as intelligence that involves self-awareness or self-sensitivity, thought processes, realizing changes that occur in oneself, involving skills of cooperation and communication both verbally and nonverbally (Alder, 2001). The characteristics of intrapersonal intelligence consist of three main aspects that can be used as benchmarks, namely recognizing oneself, knowing one's own desires, and knowing what is necessary for oneself.   Findings The results of data analysis, it was found that the learning activities that had taken place so far only used expository learning strategies. The teacher does not apply learning strategies that are in accordance with the internal factors of students in learning mathematics. The literature review show that there is a match between the characteristics of junior high school mathematics material, the characteristics of BBL learning strategies and the characteristics of intrapersonal intelligence. Therefore, the implementation of BBL learning strategies and intrapersonal intelligence in junior high school mathematics learning is very well done to improve student learning outcomes.   Acknowledgement This study was supported by Universitas Negeri Jakarta and SMP Assahil Lampung Timur, for which thanks to 1) Doctoral Program in Educational Technology, Postgraduate Program at Universitas Negeri Jakarta; 2) SMP Assahil Lampung Timur; 3) Prof. Dr. M.
