Problem-solving ability is a characteristic of mathematical activities and a major ability in developing mathematical understanding. Mathematical problem-solving ability can be seen from several dimensions, one of which is cognitive style. Cognitive style is a unique way for each individual to acquire, process, store, use the information to respond to tasks or situations, and build knowledge. FD and FI cognitive styles are one type of cognitive style that are categorized by general ways of thinking, solving problems, learning, and dealing with other people so that they have a relationship with problem-solving abilities. The subjects in this study involved 72 students (around the age of 13-14 years), namely 33 students with FD cognitive style and 39 students with FI cognitive style. The problem-solving ability test instrument in this study was a mathematical problem-solving ability test that had been validated by experts and tested for reliability. The cognitive style test instrument is the Group Embedded Figure Test (GEFT) item developed by Witkin. The problem-solving ability of junior high school students with FI cognitive style is better than FD students even though the difference is not much different.

This quasi-experimental research aims to determine the effect of Think Pair Check (TPC) learning models on understanding of mathematical concepts in terms of cognitive style. A purposive sampling technique was used to select a sample of 54 students from a junior high school in Patamuan sub-district, Indonesia. The data were obtained from mathematical concept understanding tests and Group Embedded Figure Test (GEFT) to determine students' cognitive styles. Data were analyzed using t-test. The findings indicated that students who learned using TPC method had a better understanding of concepts than those learning using the conventional model. Furthermore, the TPC learning model positively influenced the understanding of mathematical concepts of students with the Field Independent cognitive style but had no influence on students with the Field Dependent cognitive style. Therefore, the TPC learning model can be used to improve the understanding of mathematical concepts, especially for students with the Field Independent cognitive style.

Understanding is constructed or reconstructed by students actively. APOS theory (action, process, object, schema) is a theory that states that individuals construct or reconstruct a concept through four stages, namely: action, process, object, and scheme. APOS theory can be used to analyze understanding of a mathematical concept. This research is a qualitative research which aims to describe impulsive and reflective students’ understanding to linear equations system based on APOS theory. Data collection techniques were carried out by giving Matching Familiar Figure Test (MFFT) and concept understanding tests to 32 students of 8th grade in junior high school, then selected one subject with impulsive cognitive style and one subject with reflective cognitive style that can determine solutions set and solve story questions of linear equation system of two variables correctly, then the subjects were interviewed. The results show that there were differences between impulsive and reflective subjects at the stage of action in explaining the definition and giving non-examples of linear equation system of two variables, show the differences in initial scheme of two subjects. At the process stage, impulsive and reflective subjects determine solutions set of linear equation system of two variables. At the object stage, impulsive and reflective subjects determine characteristics of linear equation system of two variables.

Penelitian ini bertujuan untuk mendeskripsikan profil kemampuan berpikir kreatif matematis mahasiswa calon guru dalam menyelesaikan masalah open-ended ditinjau dari gaya kognitif reflective dan impulsive. Penelitian ini adalah penelitian deskriptif kualitatif. Subjek penelitian ini adalah mahasiswa calon guru pada Program Studi Pendidikan matematika, Universitas Muhammadiyah Prof. DR. HAMKA yang diambil menggunakan teknik purposive sampling. Validasi data menggunakan teknik triangulasi waktu. Data dianalisis menggunakan metode perbandingan tetap (constant comparative method) dengan langkah (1) reduksi data dan kategorisasi, (2) penyajian data; dan (3) penarikan kesimpulan dan verifikasi. Hasil penelitian menunjukkan bahwa dari empat indikator kemampuan berpikir kreatif matematis, mahasiswa dengan gaya kognitif reflective mampu memenuhi aspek kelancaran dan keterincian, yaitu menjawab soal dengan lebih lancar, mampu menjelaskan hubungan sebab akibat antar konsep yang digunakan, serta lebih rinci dan runtut dalam menjawab dan menjelaskan jawaban tertulisnya, dibandingkan dengan mahasiswa dengan gaya kognitif impulsive. Indikator aspek keluwesan dan kebaruan masih belum bisa terpenuhi karena mahasiswa dengan gaya kognitif reflective dan impulsive baru mampu menjawab pertanyaan menggunakan satu cara saja dan belum menggunakan strategi baru. Profile of mathematical creative thinking ability viewed from reflective and impulsive cognitive style AbstractThe study aimed to describe mathematical creative thinking ability profiles of prospective students in solving open-ended problems in terms of reflective and impulsive cognitive styles. The research classified as a qualitative descriptive study. The subjects of this study were prospective students of the Mathematics Education Department, Universitas Muhammadiyah Prof. DR. HAMKA and selected using a purposive sampling technique. For data validation, we used time triangulation techniques. Data were analyzed using the constant comparison method with steps (1) data reduction and categorization; (2) data presentation; and (3) conclusions and verification. The results showed that from the four indicators of mathematical creative thinking, students with reflective cognitive style were able to fulfill fluency and detail aspects in answering questions, explain causal relationships between concepts used, and more detail in written answers, compared to students with impulsive cognitive style. The indicators of flexibility and originality aspects of both students with the reflective and impulsive cognitive style are still cannot be fulfilled because they only answer questions using one method without using a new strategy.
