Abstract

The purpose of this research was to know the thinking processes of climber, camper, and quitter high school students in solving mathematical problems. This research used a qualitative descriptive method. Subjects were determined by purposive sampling. The technique of collecting data was done by task-based interviews. Based on the results of data analysis it can be concluded that: (1) the profiles of climber’s thinking processes are: (a) assimilation and abstraction  in understanding problems, (b) assimilation, accommodation, and abstraction in planning problem solving (c) assimilation, accommodation, and abstraction in implementing the plan of problem solving, and  (d) accommodation in checking the solution; (2) the profiles of camper’s thinking processes are: (a) assimilation in understanding mathematical problems, (b) assimilation, accommodation, and abstraction in planning problem solving, (c) abstraction in implementing the plan of problem solving, and (d) assimilation in checking the solution; (3) the profiles of quitter’s thinking processes are: (a) assimilation and abstraction in understanding problems, (b) assimilation, accommodation, and abstraction in planning problem solving, (c) assimilation, accommodation, and abstraction in implementing the plan of problem solving, and (d) assimilation in checking the solution.

Abstract

[English]: This study was aimed to describe the abstraction process of students with different cognitive styles in learning common tangent lines of two circles using recognizing, building-with, and construction (RBC) model. This qualitative research collected data through questionnaires, written tests, and task-based interviews. Eight students with field-dependent and field-independent were involved as the subjects. The interview transcripts were analyzed and grouped into cognitive actions of the RBC model. Findings showed that to reach the stage of construction activities, field-dependent students tend to need guidance and more time in recognizing and constructing the concept of a common tangent of two circles using their prior knowledge. Meanwhile, field-independent students tend to directly recognize and construct the concept using their prior knowledge so that they successfully constructed the concept of common tangent lines of two circles. This study shows that (1) field-dependent students use their prior knowledge that relates to the concept of common tangent lines of two circles less than field-independent students who tend to be able to use most of their prior knowledge relevant to the concept of common tangent lines of two circles, and (2) students who has similar cognitive style may not show the same success in abstraction process. Keywords: Abstraction, Circles, Common tangent line, Cognitive style, RBC Model [Bahasa]: Penelitian kualitatif ini bertujuan untuk mendeskripsikan abstraksi siswa SMP dengan gaya kognitif berbeda dalam mempelajari garis singgung pada dua lingkaran yang dianalisis menggunakan model RBC (Recognizing, Building-with, Construction). Data penelitian dikumpulkan melalui angket, tes tertulis, dan wawancara berbasis tugas. Delapan siswa dengan gaya kognitif field-dependent dan field-independent dipilih sebagai subjek penelitian. Data penelitian dianalisis berdasarkan rekaman wawancara yang sudah ditranskrip dan dikelompokkan berdasarkan tindakan kognitif model RBC. Hasil penelitian menunjukkan bahwa siswa field-dependent cenderung memerlukan petunjuk dan waktu lebih lama untuk mengenali dan membangun konsep garis singgung pada dua lingkaran melalui pengetahuan terdahulu hingga sampai pada aktivitas konstruksi. Sementara siswa field-independent cenderung langsung mengenali dan membangun konsep garis singgung pada dua lingkaran melalui pengetahuan terdahulu sehingga berhasil mengkonstruksi konsep garis singgung pada dua lingkaran. Penelitian ini menunjukkan bahwa (1) siswa field-dependent lebih sedikit menggunakan pengetahuan terdahulu yang berkaitan dengan konsep garis singgung dua lingkaran daripada siswa field-independent yang cenderung dapat melihat sebagian besar pengetahuan lama yang relevan dengan konsep garis singgung dua lingkaran, (2) siswa dengan gaya kognitif yang sama belum tentu menunjukkan keberhasilan yang sama pada proses abstraksi. Kata kunci: Abstraksi, Dua lingkaran, Garis singgung, Gaya kognitif, Model RBC

Abstract

The application of physical distancing during the pandemic has prompted the government to require schools to implement distance learning. One of the learning approaches that can be applied to carry out school activities today is STEAM learning. For this reason, this service activity aims to train junior high school mathematics teachers in Karanganyar district to be able to design study plans, learning media and assessment instruments. Based on this goal, the community service team carried out a workshop activity at Junior High School 1 Kerjo Karanganyar and POKJA II Karanganyar consisting of 25 teachers. There were two resource persons who assisted in the implementation of the workshop about material on the concept and implementation approach and designing a board game for learning. To find out the understanding of the teachers before and after the training, a questionnaire was used. The results of the questionnaire were analyzed using qualitative method. From community service activities, the following results were obtained, the teachers had (1) understood the concept and implementation of STEAM learning; (2) able to develop learning tools in the form of lesson plans, learning media and assessment instruments; (3) implementing limited STEAM learning

Abstract

The aim of this community service activity is to introduce the use of mathematics learning media for the topic of fractions, called Fraction Bakery, which has been developed by the service team in the Contemporary Mathematics Education research group for 2 years, both in tangible and online game forms. The initial development of the Fraction Bakery educational media was based on the complaints and difficulties expressed by students and teachers in learning and teaching fraction concepts. As fractions have various forms and are related to decimal numbers, percentages, and comparisons, selecting suitable learning models and media for elementary school students becomes crucial. Choosing an interactive learning model or media that is enjoyable for students, considering that the target users are students who are still in the concrete operational stage based on Piaget's developmental theory, is important. The development of Fraction Bakery media followed the five-stage R&D ADDIE model. Training programs were conducted using the School-Based and Collaborative Teacher Professional Development (TPD) approach, with the SUN program as a dissemination strategy. The training included mentoring sessions for teachers by media experts from PT Sebangku Jaya Abadi in collaboration with the research team. The training sessions, which took place over 32 hours at SD Negeri 15 Sragen, received highly positive responses from participants. Approximately 86.45% of teachers expressed that the material was suitable for their teaching needs, 87.5% found it easy to implement, 90.6% acknowledged the practical benefits of the training, and 89.58% found the material engaging.

Abstract

This research aims to determine the effect of implementing the CORE learning model with the CRT approach on problem-solving abilities from a self-regulated learning perspective. This study was conducted as a quasi-experimental method with a 2×3 factorial design. The population included all eighth-grade students of SMP Negeri 1 Semin in the 2025/2026 academic year, with 32 students from classes VIII D and VIII A selected using cluster random sampling. Data were obtained through problem-solving ability tests, SRL questionnaires, and documentation. Data analysis was performed using a two-way ANOVA with a significance level of 0.05. The results showed that implementing the CORE learning model with the CRT approach improved problem-solving abilities, the level of self-regulated learning had a positive effect on problem-solving abilities, and the effect of the learning model on problem-solving abilities was independent of self-regulated learning, and vice versa. The CORE learning model with the CRT approach can be implemented and modified using technology-based learning media to improve problem-solving abilities.
