Abstract

This research aims to analyze the development of mathematics teaching materials in the context of child-friendly schools from 2019 to 2024. As an approach that links mathematical concepts with local culture, ethnomathematics has great potential to support inclusive, contextual, and meaningful learning, especially in elementary schools. This research uses a systematic literature review method with a biometric approach analyzed using OpenRefine, VosViewer, Biblioshiny, and Microsoft Excel. Data were taken from scientific articles published in the Scopus database with a focus on mathematics teaching materials and the concept of child-friendly schools. The analysis process includes the identification of research trends, collaboration among researchers, geographical distribution, and the visualization of relationships between main keywords in the relevant literature. The research results indicate that the topic of ethnomathematics is gaining more attention among academics, but a lack of teacher understanding and limited teaching materials still hinders its application in the field. Adequate teacher training also poses a barrier to the implementation of mathematics in schools. Nevertheless, the analysis results indicate a significant opportunity for further research, especially with the increase in the number of publications in recent years. This recommends close collaboration between educators, curriculum developers, researchers, and local communities to strengthen the implementation of ethnomathematics in creating an inclusive and child-friendly learning environment to improve the quality of primary education in Indonesia.

Abstract

Penelitian terdahulu menunjukkan bahwa soal-soal matematika dengan banyak cara penyelesaian atau bertipe multiple solution methods (MSM) jarang diberikan di dalam kelas. Penelitian ini berfokus untuk menyelidiki (1) bagaimana penilaian mahasiswa calon guru matematika terhadap soal bertipe MSM pada materi SPLDV dan apakah terdapat perbedaan antar universitas, dan (2) alasan yang melatarbelakangi penilaian tersebut. Metode penelitian ini adalah survey dengan responden merupakan mahasiswa calon guru matematika (N = 282) dari Universitas Mulawarman, Universitas Negeri Semarang, dan Universitas Pattimura. Instrumen penelitian memuat 4 butir soal dimana setiap soal diselesaikan dengan 3 cara berbeda tetapi semuanya benar: Cara A (penyelesaian diajarkan dalam SPLDV), Cara B (penyelesaian tidak diajarkan dalam materi SPLDV), cara C (penyelesaian dengan strategi heuristik, seperti menggunakan gambar, tabel, pola, atau tebakan). Setiap responden diminta memberikan skor penilaian 0-10 ke masing-masing cara A, B, dan C beserta alasannya. Hasil penelitian menunjukkan tidak terdapat perbedaan penilaian calon guru antar universitas terhadap penyelesaian A (p =0,058 > 0,050) dan penyelesaian B (p = 0,073 > 0,050), sedangkan untuk penilaian C terdapat perbedaan penilaian antar universitas (p = 0,016 < 0,050). Penelitian juga menemukan bahwa penilaian calon guru terhadap cara C lebih rendah daripada cara A dan B. Dengan demikian, calon guru matematika memberikan skor penilaian yang tinggi terhadap cara yang diajarkan dalam matematika dan menurunkan skor penilaian yang caranya tidak diajarkan dalam materi matematika karena disebabkan beberapa faktor, yaitu. kejelasan/kelengkapan, kesesuaian dan kebenaran, keefisienan, kekreatifan, kelogisan/kekritisan, ketelitian dan kesesuaian tingkat berpikir.

Abstract

Developing thinking processes requires unusual treatment and stimulation, such as solving controversial mathematical problems. Problem-solving involves various stages of thinking and producing solutions based on decision-making. However, many students do not go through these stages perfectly, resulting in less optimal decision-making. This research aims to describe students' mathematical thinking processes in solving controversial problems based on decision-making types. The study uses a qualitative descriptive method by selecting 33 student subjects and grouping them based on decision-making types: empirical, heuristic, and rational. The grouping is based on scores from a decision-making type questionnaire, then 5 subjects are selected based on decision-making type, ability to answer questions, and mathematical communication. The instruments used in this study include a decision-making type questionnaire and controversial mathematical problems adapted from instruments developed by experts. Data is analyzed in three stages: data reduction, data presentation, and conclusion drawing. Empirical decision type (EM): Only successful up to the stages of generalizing and guessing, with difficulties in the convincing stage. Heuristic decision type (HE): Effective in specializing, generalizing, and guessing in the first problem but only meets two indicators in the convincing stage. Rational decision type (RA): Difficulty in the convincing stage and challenges in meeting the last stage indicators. The results of this study reveal the thinking process for each decision-making type when solving controversial mathematical problems. The thinking process holds significant importance, thus requiring special attention, especially from teachers, in monitoring students' thinking processes in the classroom.Mengembangkan proses berpikir memerlukan perlakuan dan stimulasi yang tidak biasa, seperti memecahkan masalah matematika kontroversial. Pemecahan masalah mencakup berbagai tahap berpikir dan menghasilkan solusi berdasarkan pengambilan keputusan. Namun, banyak siswa tidak menjalani tahapan ini dengan sempurna, sehingga keputusan yang diambil kurang optimal. Penelitian ini bertujuan untuk mendeskripsikan proses berpikir matematis siswa dalam memecahkan masalah kontroversial berdasarkan tipe pengambilan keputusan. Penelitian ini menggunakan metode deskriptif kualitatif dengan memilih 33 siswa siswa dan dikelompokkan berdasarkan tipe pengambilan keputusan, yaitu empiris, heuristik, dan rasional. Pengelompokan tersebut berdasarkan skor pada kuesioner tipe pengambilan keputusan, kemudian dipilih 5 siswa berdasarkan tipe pengambilan keputusan, kemampuan menjawab soal dan komunikasi matematis. Instrumen dalam penelitian ini berupa kuesioner tipe pengambilan keputusan dan soal kontroversial matematis yang merupakan adaptasi dari instrumen yang dikembangkan oleh para ahli. Data dianalisis dalam tiga tahap, yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Tipe pengambilan data empiris (EM): Hanya berhasil sampai pada tahap menggeneralisasi dan menduga, kesulitan pada tahap meyakinkan. Tipe pengambilan heuristik (HE): Efektif pada tahap mengkhususkan, menggeneralisasi, dan menduga pada soal pertama, namun hanya memenuhi dua indikator pada tahap meyakinkan. Tipe pengambilan keputusan rasional (RA): Kesulitan pada tahap meyakinkan dan kesulitan dalam memenuhi indikator tahap terakhir. Hasil penelitian ini mengungkapkan proses berpikir untuk setiap tipe pengambilan keputusan ketika menyelesaikan masalah matematika kontroversial. Proses berpikir memiliki arti penting, sehingga memerlukan perhatian khusus, terutama dari guru, dalam memonitor proses berpikir siswa di dalam kelas.

Abstract

The 21st-century skills are critical thinking skills and creative thinking skills. These skills are needed by someone to be successful in facing challenges, an increasingly complex and uncertain life, and to be successful in life and career in the world of work. This study aims to analyze critical and creative thinking skills in terms of the inquiry component in science learning in elementary schools. The research sample is elementary school students, with a total of 31 students. Data collection techniques used in this study were observation, tests, interviews, and documentation. The experimental research method used in this research is quasi-experimental. Quasi-experimental is used so that researchers can analyze the differences between the two treatments in the control class and the experimental class. The research design used was a non-equivalent control group design. The results of the analysis of critical and creative thinking skills for the control class inquiry model were 45.3% and 54.7%. In comparison, the experimental class obtained 65.5%, so the influence of the inquiry model on experimental class students is greater than the control class. The inquiry model has a positive effect on critical and creative thinking skills. With this research, the inquiry model can improve the critical thinking skills and creative thinking of fifth-grade elementary school students in science learning.

Abstract

In learning mathematics, reflective thinking is often overlooked due to an excessive emphasis on final results, which causes students to struggle in evaluating and reconstructing their problem-solving processes. Reflective thinking skills are necessary for students to solve problems, including numeracy. This study adopts a qualitative approach, focusing on the problem-solving process of two seventh-grade students with a Dependent Field (DF) cognitive style and similar initial mathematical abilities. Data were collected through the Group Embedded Figures Test, in-depth interviews, and initial mathematical and reflective thinking ability tests. Based on the research results, DF students couldn't analyze arguments from various perspectives and see if there were deeper implications. This finding reflects the characteristics of DF, who don't perform the 'result in context' process, leading to a lack of ability to understand, interpret, and use numerical results in concrete/situational contexts. This also includes the ability to relate numbers to real-world situations, make appropriate interpretations, and take suitable actions based on those numerical results. The results of this study can serve as a foundation for designing differentiated instruction that emphasizes the development of reflective thinking skills, particularly in numeracy, through approaches involving technology, models, pedagogy, or other learning strategies.

Abstract

This research aims to analyze the resilience capabilities of Early Childhood Education (ECE) teachers in facing professional and contextual challenges through a Systematic Literature Review (SLR) approach. Using the PRISMA method, 12 articles from 2015–2024 were identified and analyzed to explore the internal and external factors of ECE teachers' resilience. The analysis results indicate that 33% of the articles highlight the role of internal resilience factors such as self-compassion, ego-resilience, and self-esteem. In comparison, 50% of the articles emphasize the importance of social support, institutional policies, and training as external resilience factors. 17% of the articles discuss the interaction between internal and external factors. These findings affirm that resilience results from a dynamic interaction between the individual and their environment. This research recommends developing resilience-based training programs and institutional policies that support the well-being of ECE teachers. With a holistic approach, early childhood education teachers are expected to be better prepared to face professional and contextual challenges that optimally contribute to supporting the development of young children.
