Abstract

Reversible thinking is a mathematical competency that influences students' success in solving problems. Problem-solving is the core of mathematics education. This research aims to identify the characteristics of students' thinking in solving problems that require reversible thinking ability. A qualitative method with a case study approach was used in this research. The study used tests and interviews on 44 eighth-grade students in West Java, Indonesia. In-depth interviews were conducted with representative students whose answers were representative of the other students. All students' answers were analyzed using the thematic analysis software ATLAS.ti. According to the characteristic indicators of reversible thinking. This study found that junior high school students' ability in reversible thinking is not optimal. Some students who successfully solve problems are limited to using backward thinking processes rather than invertible ones. The other students still have difficulties constructing answers due to the limited context when students first learn the concept (problems with forward-thinking). Thus, this ability needs to be understood by students as one factor that supports the success of the problem-solving process.

Abstract

The professional competence of Madrasah Ibtidaiyah (MI) teachers in teaching ratio material is a vital factor in improving students’ understanding of mathematics, making it important to examine MI teachers’ knowledge of mathematics content. This study aims to analyze teachers’ professional skills, including their understanding of the concept of ratios, their attitudes toward preparing the learning process, such as creating teaching materials aligned with the curriculum, and their understanding of students’ characteristics and how they design learning. The results of this study provide an initial foundation for further research, which can help teachers develop learning methods through didactic studies. The subjects of this research are MI grade VI teachers in Bandung Regency, from six schools. The method used is a descriptive approach with a prospective analysis stage based on Didactical Design Research (DDR). Data collection involved teacher reflection sheets, exploratory interviews, observations, and document reviews. The findings indicate that teachers’ professional competence in knowledge of learning content and teaching methods remains at level 2, while their understanding of students’ characteristics and learning styles is at level 3. Reflection sheets and interviews reveal that teachers face difficulties beginning with defining ratios, particularly in understanding that the ratio of a to b differs from the ratio of b to a, and in solving problems involving equal proportions. Often, teachers plan their lessons with a simple sequence of materials in a journal, without considering the epistemic and systemic aspects of the content or validating their presentation and practice questions found in textbooks. MI teachers also find it challenging to select concrete teaching methods for ratios before moving to an abstract understanding, especially given the limited time. Based on these findings, there is a clear need for programs to improve teachers’ competence through didactic studies, equipping them to anticipate and address potential obstacles and enabling them to design compelling learning experiences. Since teachers’ professional competence in teaching ratios directly impacts students’ understanding of math, exploring their content knowledge is essential. This study contributes to empowering teachers through didactic design research, a necessary approach to enhancing teacher competence.

Abstract

Persistent evidence from national and international assessments indicates that students’ numeracy achievement remains low, suggesting a gap between intended curriculum goals and classroom implementation. This study conducts an illuminative evaluation of secondary mathematics curriculum implementation as an instructional system, examining how curriculum enactment relates to students’ numeracy achievement in the Indonesian secondary context. Employing a sequential explanatory mixed-methods design, the quantitative phase assessed the numeracy performance of 288 secondary students across content domains, cognitive levels, and item formats, while the qualitative phase investigated instructional practices, assessment culture, and the school learning milieu to explain the observed achievement patterns. The findings indicate uneven numeracy achievement, with performance concentrated at procedural levels and declining from knowing to applying and reasoning. Students perform relatively better on objective formats but demonstrate a limited ability to justify solutions in open-ended tasks. Qualitative evidence further indicates a misalignment between reasoning-oriented curriculum intentions and efficiency-driven classroom practices that emphasize procedural accuracy. These findings provide evidence-based insights into aligning curriculum design, classroom instruction, and assessment practices to strengthen reasoning-oriented numeracy learning.

Abstract

Adaptive reasoning is one of the five strands in mathematical proficiency. It reflects students’ capacity to think logically and justify their reasoning when solving mathematical problems, particularly in the topic of composition of functions. This study aims to analyze students’ errors in solving adaptive reasoning problems on the topic of composition function based on Newman’s Theory. The type of research used is qualitative research using a diagnostic test and interviews as instruments. The subjects of this study were 16 eleventh-grade students at a high school in Berau Regency in Kalimantan Timur Province. The results of this study show that students’ errors occur at the understanding stage, transformation stage, process skills stage, and the solution process stage. In the argumentation indicator, students experienced errors at the comprehension stage by 100%. In the inference indicator, errors occurred at the transformation stage by 43.75% and the process skills stage by 37.5%. Furthermore, on the validation indicator, students’ errors in the process skill stage at 6.25% and the completion process stage at 18.75%. The type of errors that majority of students experienced was the comprehension stage on the argumentation indicator.

Abstract

Kemampuan numerasi siswa sekolah menengah di Indonesia menunjukkan kesenjangan yang jelas antara penguasaan soal rutin dan kemampuan menalar, menafsirkan data, serta memahami konteks. Kondisi ini menuntut pemetaan yang lebih komprehensif untuk memahami variasi capaian numerasi berdasarkan domain, level kognitif, dan karakteristik asesmen. Penelitian ini bertujuan memetakan kompetensi numerasi siswa SMA dan SMK di Provinsi Riau serta mengidentifikasi faktor pembelajaran, strategi guru, dan karakteristik soal yang memengaruhi hasil tersebut. Metode yang digunakan adalah mixed methods dengan desain sekuensial eksplanatori, melibatkan tes kuantitatif pada 288 siswa dan wawancara mendalam dengan guru serta siswa dari dua sekolah berprestasi tinggi. Instrumen tes mencakup 30 soal numerasi yang merepresentasikan tiga domain (geometri & pengukuran, aljabar, data & ketidakpastian), tiga level kognitif (Knowing, Applying, Reasoning), dan enam jenis soal. Hasil penelitian menunjukkan pola capaian hierarkis yang menurun dari Knowing ke Reasoning dengan perbedaan signifikan antar domain dan jenis soal. Capaian terendah ditemukan pada domain data dan ketidakpastian serta soal uraian yang menuntut penalaran tingkat tinggi dan interpretasi teks panjang. Temuan kualitatif menegaskan bahwa kesulitan utama siswa berkaitan dengan beban kognitif saat membaca konteks, keterbatasan hubungan konseptual–prosedural, dan kurangnya pembelajaran berbasis situasi nyata. Penelitian ini menyimpulkan bahwa peningkatan numerasi memerlukan pendekatan pembelajaran yang mengintegrasikan literasi membaca, penalaran matematis, dan strategi pedagogis reflektif secara berkelanjutan.

Abstract

Masalah yang terjadi pada pembelajaran matematika seringkali disebabkan oleh materi matematika yang abstrak, sehingga sulit bagi peserta didik untuk memahaminya terutama pada materi program linear. Peserta didik dituntut untuk mampu memahami kalimat pada soal dan mengubahnya menjadi model matematika, serta mampu membuat dan membaca grafik. Materi yang abstrak ini perlu dipoles dengan penyampaian tulisan yang mengajak belajar serta tampilan yang menarik, dengan begitu penyampaian materi mampu dipahami oleh peserta didik. Salah satu solusi yang diberikan ialah dengan membuat lembar kerja peserta didik (LKPD) yang berbasis model treffinger yang praktis agar dapat diterapkan dalam kegiatan pembelajaran matematika pada materi program linear. Jenis penelitian ini yaitu Research and Development (R&D) dengan menggunakan model 4-D yaitu Define, Design, Develop, dan Disseminate. Penelitian dibatasi sampai pada tahap develop dikarenakan hanya melakukan uji praktikalitas. Pengambilan data praktikalitas dilakukan dengan memberikan angket respon kepraktisan kepada seorang guru matematika dan 27 orang peserta didik kelas XI di SMA Kota Medan, Sumatera Utara. Penelitian sebelumnya menunjukkan bahwa tahap define, design, dan develop telah teruji dengan hasil kevalidan dinyatakan sangat valid. Hasil uji praktikalitas pada peserta didik diperoleh sebesar 3,6 dengan kategori praktis. Demikian bahwa LKPD berbasis model treffinger praktis digunakan dalam kegiatan pembelajaran matematika pada materi program linear.   Problems that occur in mathematics learning are often caused by abstract mathematical material, making it difficult for students to understand, especially in linear program. Students are required to be able to understand the sentences in the problem and convert them into mathematical models, as well as being able to create and read graphs. This abstract material needs to be polished with the delivery of writing that invites learning and an attractive appearance, so that the delivery of material can be understood by students. One of the solutions provided is to make worksheets based on the practical Treffinger model, so they can be applied in mathematics learning activities on linear program. This type of research is Research and Development (R&D) using the 4-D model, namely Define, Design, Develop, and Disseminate. Research was limited to the development stage due to the practically test only. Practicality data were collected by giving a practicality response questionnaires to a mathematics teachers and 27 student grade XI at SMA in Medan City, Sumatera Utara Province. The previous research show that the define, design, and develop stages have been tested with the results of the validity declared very valid. The results of the practicality test on students were obtained at 3.6 with the practical category. Thus, the LKPD based on the Treffinger model is practically used in mathematics learning activities on linear program.

Abstract

The mathematics learning outcomes of students in class X APHP 1 SMKN Pertanian Terpadu Provinsi Riau in the 2022/2023 academic year show that the percentage of classical achievement is only 35.9 percent. From the reflection of the learning process carried out by the teacher, the following conclusions: (1) the learning process was still teacher-centered; (2) during the teaching and learning process, only a small number of students actively participated in the teaching and learning process; (3) there were still students who did not do their work and only copied their friends' work. This study aims to increase students' activity and learning outcomes by applying the Think Pair Share cooperative learning model. This type of research is Classroom Action Research with two cycles. The subjects of this study were 39 students of class X APHP 1 at the SMKN Pertanian Terpadu Provinsi Riau. The results showed that applying the TPS type of cooperative learning model can be active in learning outcomes, as seen by an increase from cycle I to cycle II. The number of students who achieved KKM in the first cycle was 79.5 percent, while in the second cycle, it was 89.7 percent. Therefore, the TPS-type cooperative learning model can be used as an alternative to learning mathematics to improve student learning outcomes.   Abstrak Hasil belajar Matematika peserta didik kelas X APHP 1 SMKN Pertanian Terpadu Provinsi Riau semester ganjil tahun ajaran 2022/2023 menunjukkan bahwa persentase ketercapaian secara klasikal hanya sebesar 35,9 persen.

Abstract

Misconceptions in mathematics education are a persistent problem with far-reaching implications across all levels of education, from preschool through higher education. This study narrows the focus on misconceptions to three main clusters that are frequently encountered and have the greatest impact on mathematics education: fractions, algebraic variables, and functions. This study aims to identify the most common forms of misconceptions, their underlying patterns, and interventions proven effective in reducing misconceptions within these three priority clusters. Using a Systematic Literature Review (SLR) approach in accordance with the PRISMA 2020 guidelines, the search was conducted across three databases, such as Scopus, ERIC, and SpringerLink, yielding 117,846 initial records. Following a multi-stage screening process, 31 articles published between 2016 and 2026 were analysed in depth. The review results indicate that the most prevalent misconceptions are related to fractions, algebraic variables, and functions. Regarding interventions, the use of technological tools such as GeoGebra, inquiry-based learning, cognitive conflict, and a bilingual approach was frequently found to have demonstrated positive effects across studies. These findings have important implications for curriculum design, teacher professional development, and the design of learning environments that are adaptive and responsive to the diversity of students’ prior conceptions.
