There is a strong relationship between field-dependent (FD), field-independent (FI) cognitive styles, and problem-solving performance. FD students are more oriented towards the outside world, while FI students rely more on their knowledge and experience. The present study aimed to reveal the position of the FI and FD student's errors in algebraic problem-solving. The subjects of this study were 27 students of class VII in one of the Junior High Schools in Kefamenanu, Indonesia, Academic Year 2018/2019. Data collection involved tests of algebraic problem-solving ability, interviews, and Group Embedded Figure Test. The case study results showed that the algebraic problem-solving abilities of FI students were better than FD students. The scores of algebraic problem-solving abilities of FI students were dominant in the medium and high categories. In contrast, the FD students were dominant in the medium and low categories. Also, FI students predominantly committed procedural errors. Whereas, most FD students made errors on all types of errors, specifically factual, conceptual, and procedural errors. Thus, it is recommended that FI and FD students' algebraic problem-solving ability become the focus of attention and importance to characterize them as a basis for further research.

The study aimed to analyze the interaction effect teaching models and cognitive style field dependent (FD)-field independent (FI) to students’ mathematical problem-solving ability (MPSA), as well as students' MPSA differences based on teaching models and cognitive styles. Participants in this study were 145 junior high school students, with details of 50 students learning through the Connect, Organize, Reflect, and Extend Realistic Mathematics Education (CORE RME) model, 49 students use the CORE model, and 46 students use the Conventional model. Data collection tools used are the MPSA test, and the group embedded figure test (GEFT). The MPSA test finds out that there are interaction effect teaching models and cognitive styles on students' MPSA, as well as a significant difference in MPSA students who study through the CORE RME model, CORE model, and Conventional model. Based on cognitive style, between students who study through CORE RME model, CORE model, and Conventional model found that there was no significant difference in MPSA between FI students. Furthermore, there were significant differences in MPSA between FD students and also MPSA of FI students better than MPSA FD students. Therefore, teaching models and student cognitive styles are very important to be considered in the learning process, so students are able to solve mathematical problems.

Kemandirian belajar membantu siswa fokus pada kegiatan kognitif yang diperlukan untuk memfasilitasi proses pemecahan masalah mereka. Namun tidak dapat dipungkiri adanya peningkatan pengakuan bahwa dalam banyak kasus, kemandirian belajar siswa cenderung rendah. Situasi ini membutuhkan strategi tertentu untuk membangkitkan kemandirian belajar siswa. Karena itu, dilakukan penelitian ini untuk mengetahui perbandingan pencapaian dan peningkatan kemandirian belajar matematika siswa berdasarkan intervensi model pembelajaran. Penelitian kuantitatif ini menggunakan pendekatan quasi eksperimen. Partisipan penelitian ini sebanyak 145 siswa pada dua sekolah menengah pertama di kota Kefamenanu, diantaranya 50 siswa belajar dengan model connecting, organizing, reflecting, extending dengan realistic mathematics education (CORE RME), 49 siswa belajar dengan model CORE, dan 46 siswa belajar dengan model konvensional. Hasil penelitian menunjukkan bahwa siswa yang belajar dengan model CORE RME memiliki pencapaian dan peningkatan kemandirian belajar matematika yang lebih baik dari siswa yang belajar melalui model CORE, dan model konvensional. Sedangkan perbandingan kemandirian belajar matematika antara siswa yang belajar melalui model CORE, dan model konvensional tidak terdapat perbedaan secara signifikan. Direkomendasikan agar dalam proses pembelajaran matematika di sekolah, perlu melibatkan prior knowledge siswa, real context, guided reinvention, self-development models, metacognition, self-monitoring, intertwining dan interactivity sehingga dapat mengembangkan kemandirian belajar matematika siswa.
