Abstract

This study aims to determine and describe the effectiveness of the use of jigsaw-flash learning model on geometry material. The jigsaw-flash learning model is a jigsaw learning model which is modified with adobe flash media. The research method used is mix method research with exploratory sequential strategy. This research was conducted in state junior high schools in Surakarta. Subjects in this study were the students of class VIII namely class VIII-2 as an experimental class and class VIII-3 as a control class selected by random sampling technique. The experimental class was taught with a jigsaw-flash learning model and the control class was taught with a jigsaw model. The procedures performed in this study include qualitative data collection and data analysis followed by quantitative data collection and data analysis. The researcher used interview method for collecting qualitative data. While quantitative data collection was conducted by test and the analysis technique used was t-test. The results of this study indicate that students feel more comfortable and interested in studying geometry material taught by jigsaw-flash model. In addition, students taught using the jigsaw-flash model are more active and motivated than the students who were taught using jigsaw models in studying geometric material. This shows that the use of the jigsaw-flash model can increase student participation and motivation. The results of this study also indicate that the increase in student achievement taught by the jigsaw-flash model which is indicated by t-test result t = 2,259 with df = 38. Based on the results, it can be concluded that jigsaw-flash model is more effective than jigsaw model. Therefore, teachers need to consider the use of jigsaw-flash learning model in learning geometry material.

Abstract

Fractions are abstract mathematical concepts that often challenge students due to their various representations. While fraction instruction in schools typically emphasizes area models, it is crucial to incorporate other models, such as length models and number lines. This study aims to 1) identify the learning obstacles students encounter in representing fractions with length and number line models, 2) develop didactic designs to address these learning obstacles, and 3) evaluate the effectiveness of the designs. Employing a qualitative approach grounded in the Didactical Design Research (DDR) framework, the study comprised three stages: prospective, metapedadidactic, and retrospective analysis. Data were collected through tests administered to 20 seventh-grade bilingual students, in-depth interviews with those experiencing difficulties, and an analysis of their learning resources. All the collected data on learning obstacles were then analyzed using the Miles & Huberman method, which involves the stages of data reduction, data display, and conclusion drawing. The findings indicate that students relied predominantly on area models due to limited instructional exposure, leading to learning obstacles when representing fractions using the length model and locating them on the number line. When asked to use the length model, students tended to revert to area representations, reflecting conceptual constraints. Based on these obstacles, a didactic design was developed in which the length model and number line were introduced sequentially and in an interconnected manner. The design proved effective, as no further learning obstacles were identified after its implementation. These findings suggest that systematically integrating both representations strengthens students’ conceptual understanding of fractions.

Abstract

The development of mathematical thinking is an important goal in mathematics learning because it relates to students’ ability to solve problems through various reasoning processes, including inductive thinking methods. However, students’ application of inductive thinking in solving mathematical problems still requires further exploration. This study aims to explore the application of inductive thinking methods in solving number pattern problems based on the perspective of mathematical thinking. The research employed a qualitative descriptive approach involving three students representing high, medium, and low levels of mathematical ability. Data were collected through a reasoning test and interviews and analyzed through data reduction, data display, and conclusion drawing. The results show that the high ability student was able to identify patterns but still experienced difficulty in formulating accurate generalizations. The medium ability student recognized some patterns but was not able to generalize correctly, while the low-ability student experienced difficulties from understanding the problem to determining general rules. These findings indicate differences in students’ inductive thinking across levels of mathematical ability. The study implies the importance of designing mathematics learning that encourages pattern exploration and generalization processes to support students’ mathematical thinking development.

Abstract

Ketersediaan buku teks matematika yang tidak sesuai dapat mempengaruhi rendahnya kinerja akademik siswa. Penelitian ini bertujuan untuk menganalisis bahan ajar matematika sekolah dari perspektif praxeologis, di mana peneliti berusaha memahami bagaimana siswa berinteraksi dengan materi yang disajikan dalam bahan ajar, bagaimana mereka membuat keputusan tentang masalah mana yang akan diselesaikan, dan bagaimana desain serta konten buku teks mempengaruhi hasil belajar mereka. Ini adalah implementasi paradigma interpretatif dalam penelitian desain didaktik. (DDR). Melalui studi dokumen (dalam penelitian kualitatif yang dirancang secara fenomenologis) pada bahan ajar matematika sekolah Indonesia versi Kurikulum Merdeka, hasil yang diperoleh adalah: Komponen tugas (T) dalam materi tentang bilangan besar menggunakan teknik operasional; Komponen teknik (τ) sesuai karena informasi yang disampaikan dalam setiap pertemuan memiliki kontinuitas; Komponen teknologi (θ) belum sesuai, sehingga perbaikan dan peningkatan diperlukan dalam pengembangan media pembelajaran berbasis teknologi informasi dan komunikasi; dan Komponen teori (Θ) belum sepenuhnya selaras dengan teori konstruktivis, di mana siswa dapat membangun pengetahuan berdasarkan pengalaman masing-masing.The availability of mathematics textbooks that are not appropriate can influence students' low academic performance. This research aims to analyze school mathematics teaching materials from a praxeological perspective, where the researcher seeks to understand how students engage with the material presented in the teaching materials, how they make decisions about which problems to solve, and how the design and content of textbooks affect their learning outcomes. This implements the interpretive paradigm in didactical design research (DDR). This study will involve three principal stages in the data analysis procedure. Through document studies (in phenomenologically designed qualitative research) on the Indonesian school mathematics teaching materials version of the Merdeka Curriculum, the results obtained are: The task component (T) in the material on large numbers uses operational techniques; The technique component (τ) is appropriate because the information conveyed in each meeting has continuity; The technology component (θ) is not yet appropriate, so improvements and enhancements are needed in the development of information and communication technology-based learning media; and The theory component (Θ) is not yet fully aligned with constructivist theory, where students can build knowledge based on their respective experiences. The praxeological study of this teaching module provides a new perspective on how task design plays an important role in making the presentation of material more acceptable to students.

Abstract

Abstrak Penalaran aljabar menjadi topik hangat dalam dua dekade terakhir, tetapi siswa sekolah menengah mengalami kesulitan dalam mempelajari hal ini, sebab mengalami transformasi dari pemikiran aritmatika ke pemikiran aljabar yang abstrak. Penelitian ini menganalisis artikel penalaran aljabar dari basis data Scopus berdasarkan tahun penelitian, metode, dan sebaran geografis dalam satu dekade. Penelitian disajikan melalui tinjauan literatur sistematis dengan menggunakan protokol PRISMA meliputi Preferred Reporting Item for Systematic Reviews and Meta-Analytic. Dari proses seleksi, didapatkan 29 artikel yang memenuhi kriteria inklusi dan lolos tiga tahap penyaringan. Penelitian dengan topik ini cenderung mengalami penurunan, terutama dalam 4 tahun terakhir. Metode yang paling sering digunakan adalah metode penelitian kualitatif karena dianggap peneliti sangat cocok untuk meneliti kemampuan berpikir. Dari 8 wilayah yang melakukan penelitian penalaran aljabar, Indonesia merupakan negara yang paling banyak melakukannya. Hal ini dilatarbelakangi rendahnya penalaran aljabar siswa. Peluang penelitian pada topik ini masih terbuka lebar dengan menggunakan penelitian ini sebagai rujukan. Abstract Algebraic reasoning has become a hot topic in the last two decades, but high school students have difficulty in learning it, because they experience a transformation from arithmetic thinking to abstract algebraic thinking. This study analyzes algebraic reasoning articles from the Scopus database based on the year of research, methods, and geographical distribution in one decade. The research is presented through a systematic literature review using the PRISMA protocol including the Preferred Reporting Item for Systematic Reviews and Meta-Analytic. From the selection process, 29 articles were obtained that met the inclusion criteria and passed three stages of screening. Research on this topic tends to decline, especially in the last 4 years. The most frequently used method is the qualitative research method because researchers consider it very suitable for researching thinking skills. Of the 8 regions that conduct algebraic reasoning research, Indonesia is the country that does it the most. This is due to the low algebraic reasoning of students. Research opportunities on this topic are still wide open by using this research as a reference.
