Hakikat belajar matematika adalah menumbuhkembangkan proses berpikir siswa. Kemampuan berpikir kreatif sangat diperlukan dalam mengatasi beranekaragam permasalahan matematis. Salah satu permasalahan matematis yang menuntut kemampuan berpikir kreatif adalah permasalahan kontroversial matematis. Penelitian ini bertujuan untuk mendeskripsikan model berpikir kreatif siswa dalam menyelesaikan permasalahan kontroversial matematis. Pendekatan penelitian yang digunakan adalah pendekatan kualitatif. Subjek penelitian berjumlah 181 siswa yang terdiri dari siswa kelas 7 dan 8 MTs Surya Buana Malang, Jawa Timur. Instrumen penelitian yang digunakan terdiri dari empat permasalahan kontroversial matematis pada materi geometri yang disusun tim peneliti. Hasil penelitian ini menunjukkan bahwa tiga level model berpikir kreatif siswa ketika menyelesaikan permasalahan kontroversial matematis meliputi imitasi, modifikasi, dan konstruksi. Pada level imitasi, subjek meniru prosedur penyelesaian masalah yang terkesan masuk nalar dengan cara menggambarkan pemecahan masalah, mengadopsi konsep penyelesaian sebelumnya, dan mendayagunakan logika saja. Pada level modifikasi, subjek mengubah objek, konsep, dan prosedur untuk menghasilkan penyelesaian. Pada level konstruksi, subjek mengembangkan hasil analisis terhadap objek maupun konsep menjadi sebuah prosedur penyelesaian masalah baru. Selain itu, setiap level model berpikir kreatif pada penelitian ini sangat dipengaruhi karakteristik dari permasalahan kontroversial, yakni perbedaan sudut pandang. Sehingga, kecenderungan subjek dalam mengimitasi, memodifikasi, dan mengkonstruksi pemecahan masalah sangat berbeda dengan permasalahan matematis lainnya. The essence of learning mathematics is to develop students' thinking processes. The ability to think creatively is needed to overcome various mathematical problems. One of the mathematical problems that require the ability to think creatively is a controversial mathematical problem. This study aims to describe students' creative thinking models in solving controversial mathematical problems. The research approach used is qualitative. The research subjects totaled 181 students in grades 7 and 8 of MTs Surya Buana Malang, East Java. The research instrument used consisted of four controversial mathematical problems in the geometry material compiled by the research team. The results of this study found that the three levels of students' creative thinking models when solving controversial mathematical problems include imitation, modification, and construction. At the level of imitation, the subject imitates problem solving procedures that seem reasonable by describing problem solving, adopting previous solving concepts, and using only logic. At the modification level, the subject changes objects, concepts, and procedures to produce solutions. At the construction level, the subject develops the results of analyzing objects and concepts into a new problem-solving procedure. In addition, each level of the creative thinking model in this study is strongly influenced by the characteristics of controversial issues, namely different points of view. Thus, the subject's tendency to imitate, modify, and construct problem solving is very different from other mathematical problems.

For students to compete with the rapid advancement in science, technology, and the arts, creativity must be more than just a necessary skill. This study of levels of creativity performed when addressing statistical issues is a follow-up to earlier studies. To create a distinctive model, a controversial aspect was used. The study revealed that there were five levels of creative models, in addition to the three levels of the earlier research: pre-imitation, imitation, modification, combination, and construction. The pre-imitation stage is defined by the subject's limited capacity for imitation. The level of imitation is determined by the act of copying methods even when one does not actually understand them. The modification level is essentially defined by the process of altering a procedure so that it can be applied to solve an issue. The process for merging several settings or problem-solving strategies also serves to define the level of combination. The construction level is determined by the process of developing new methods to handle problems.

The study's purpose is to describe the cognitive conflicts experienced by students with relational understanding when solving the problem of three-term ratios. The current research is a case study with a qualitative approach using a purposeful sampling technique. The three research objects are representations of the condition that (1) the student was sure of his solution (cognitive conflict was solved) and the solution is correct, (2) the student was confident with his solution (cognitive conflict was solved) but the solution is not correct, and he is not confident with the solution (cognitive conflict was not solved), and the solution was not correct. The results of this study describe students with relational understanding experience cognitive conflicts, that is, being aware of the conflict between the initial concepts they have and the results obtained. Students feel doubtful and worried, as indicated by the awareness that the initial scheme applied to one proportion problem cannot be applied to other comparison questions. Students' cognitive conflicts with relational understanding do not always lead them to get the correct solution to the three-term ratio problems. The reason is that the student believes comparison is wrong (misconception).

Student metacognition only focuses on individuals, not yet associated with student positioning in the group. There are positioning groups whose roles change, so it is necessary to examine more deeply the characterization of students' metacognition in solving multiplication problems in group discussions in terms of student positioning. This study aims to describe students' metacognitive activities, students' roles during the discussion process, and students' metacognitive abilities related to students' roles during group discussions on multiplication material in mathematics of grade 6 students in one of the public elementary schools in Indonesia. Not only knowing the concept so that students can think critically and learn independently from students without teacher assistance, but also students must be trained in solving problems. This study used descriptive qualitative as the research method. It was found that awareness was mainly found in expert and facilitator positions, regulation was found in expert and facilitator students, and evaluation was found in all student roles. The metacognitive characteristics that emerged in group discussions were expert students as triggers (stimulus) and regulators (contribution), facilitator students as regulators (contribution) and followers (passive), and novice students as followers (passive).Metakognitif siswa hanya berfokus terhadap individu, belum dikaitkan dengan pemosisian siswa dalam kelompok. Ada kelompok pemosisian yang perannya berubah, sehingga perlu mengkaji lebih mendalam terkait karakterisasi metakognitif siswa dalam menyelesaikan masalah perkalian pada diskusi kelompok ditinjau dari pemosisian siswa. Penelitian ini bertujuan untuk mendeskripsikan aktivitas metakognitif siswa, peran siswa selama proses diskusi, dan kemampuan metakognitif siswa yang terkait dengan peran siswa selama diskusi kelompok pada materi perkalian matematika siswa kelas 6 di salah satu sekolah dasar negeri di Indonesia. Tidak hanya mengetahui konsep agar siswa dapat berpikir kritis dan belajar secara mandiri dari siswa tanpa bantuan guru, tetapi juga siswa harus dilatih dalam memecahkan masalah. Penelitian ini menggunakan deskriptif kualitatif sebagai metode penelitian. Ditemukan bahwa kesadaran terutama ditemukan pada posisi ahli dan fasilitator, regulasi ditemukan pada siswa ahli dan fasilitator, dan evaluasi ditemukan pada semua peran siswa. Karakteristik metakognitif yang muncul dalam diskusi kelompok adalah siswa ahli sebagai pemicu (stimulus) dan pengatur (kontribusi), siswa fasilitator sebagai pengatur (kontribusi) dan pengikut (pasif), dan siswa pemula sebagai pengikut (pasif).

[Title: The Students' Understanding of Equal Sign in Completing Mathematics Tasks]. This study aims to describe the student's understanding of the equal sign to solve mathematical tasks. This study was included in the qualitative descriptive study. In this study, the data collected is the data of student’s work and verbal data (the interview). The subjects were six students of 7th class of MTs Attariqie Malang 2014/2015 (Junior High School), with details of two high-ability students, two students capable of being, and two low-ability students. Students' understanding of the equal sign examined further by providing tests and interviews in six research subjects. Interviews were conducted individually after the students work on the problems individually. The mathematical task load arithmetic and algebra problems. Based on the results of the study, all subjects were able to understand the equal sign as operational and the equal sign as a substitution. For equal sign as the basic relational, only high-ability students were able to understand it. Understanding of medium and low student capable entrenched in the operational pattern that is an equal sign as operational cause confusion to understanding equal sign as the basic relational, eg, 14+11=25+8 where students only pay attention to the results of operations that 14 plus 11 is 25 without notice relation of the addition of 8.

Small group discussions (group work) are an important part of the learning process though students are rarely skilled at asking a question. The purpose of this study is to examine student interactions and questioning skills during group work. This research study uses a qualitative descriptive approach. The research subjects consist of eight students who were divided heterogeneously into two groups, with four members for each group. The research instrument consists of the researcher herself, a task in the form of a trigonometric ratio group worksheet, and three video cameras to observe discussion activities. One camera was focused on all class activities and two cameras were pointing at each group being observed. All conversation transcripts during the discussion are deciphered, coded, and then analyzed qualitatively. The results of this study show the interaction of conveying opinion/rebuttals, asking questions, and providing answers, with the percentage of giving opinions/ objections were more dominant than other interactions. The ability to ask questions was obtained by 50% of the students having the medium questioning ability and 50% having the low questioning ability, with the level of questions asked at the LOTS level, namely C1 and C3 levels. None of the students had high questioning skills. Of the two groups observed, group A was more active in interacting both in terms of exchanging opinions/rebuttals, asking questions, and providing answers. Suggestions for further research need to be carried out an in-depth analysis of discussion activities both in terms of asking questions or providing feedback to see the emergence of collaborative reasoning.
