Signifikansi kemampuan komunikasi matematis dalam perolehan matematika menjadi latar belakang penelitian ini. Banyak penelitian yang dilakukan di Indonesia menjawab permasalahan rendahnya kemampuan komunikasi matematika. Temuan serupa juga ditemukan peneliti di MTsN 3 Agam. Fakta bahwa instruktur terus menggunakan teknik pengajaran yang tidak sesuai dan memberikan sedikit arti penting pada kelas mereka merupakan salah satu elemen yang mempengaruhi seberapa baik siswa mengkomunikasikan ide-ide matematika. Strategi pembelajaran yang dikenal sebagai pengulangan intelektual pendengaran menawarkan solusi yang mungkin untuk masalah ini. Tujuan penelitian ini adalah untuk mengetahui ada tidaknya kemampuan komunikasi matematis siswa MTsN 3 Agam kelas VIII dipengaruhi secara signifikan oleh paradigma pembelajaran Auditory Intellectually Repetition. Memanfaatkan pendekatan penelitian Static Group Comparison, penelitian ini bersifat pra-eksperimental. Penelitian ini mengikutsertakan seluruh kelas VIII MTsN 3 Agam sebagai partisipan. Kelas VIII.2 dijadikan sebagai kelas eksperimen dan kelas VIII.1 dijadikan sebagai kelas kontrol dalam penelitian ini menggunakan teknik sampel acak. Penelitian ini menggunakan tes keterampilan komunikatif matematika. Siswa yang belajar dengan menggunakan model pembelajaran Auditory Intellectually Repetition mempunyai kemampuan komunikasi matematis yang lebih kuat dibandingkan siswa yang belajar dengan teknik standar, menurut pemeriksaan data penelitian. Thitung = 1,91294 dan Ttabel = 1,671, hasil uji hipotesis menunjukkan hal tersebut; pada tingkat kepercayaan α = 0,05, thitung > ttabel, menunjukkan diterimanya H1. Diketahui bahwa strategi pembelajaran Auditory Intellectually Reptition mempunyai pengaruh yang cukup besar terhadap kemampuan komunikasi matematika siswa kelas VIII MTsN 3 Agam.

Abstract

Low mathematics learning outcomes and students' mathematics activities and the learning process tend to be centered on the teacher. One alternative to overcome this problem is to apply the Auditory Intellectually Repetition (A.I.R.) learning model. Student activity is seen from the student activity sheet data, including whether the student is included in the criteria categorized as active or very active. The study aimed to determine whether the ability of students' mathematics learning outcomes and students' mathematics activities using the Auditory Intellectually Repetition (A.I.R.) model was better than conventional learning for class VIII students of MTsN 3 Lima Puluh Kota—the type of pre-experimental research with a Static Group Comparison Design research design. The population of the study was all students of class VIII MTsN 3 Lima Puluh Kota, consisting of 3 classes. The research sample consisted of students from class VIII.3, as an experimental class, and students from class VIII.2, as a control class, using the simple random sampling technique. The research instrument tested students' mathematics learning outcomes through essay questions—data analysis techniques with percentages for student learning activities and t-tests for students' mathematics learning outcomes. Based on the results of the analysis and student learning activities, an average rate of 90.56% was obtained with the criteria of very active. Meanwhile, from the analysis of students' mathematics learning outcomes data, it was obtained that tcount > ttable, namely tcount = 11.50 and ttable = 1.67. The testing criteria are accepted H0 if tcount > ttable; otherwise, reject H0. Based on the calculation, it was obtained that tcount > ttable, namely 11.50 > 1.67, meaning that H0 was rejected and H1 was accepted, so the Auditory intellectual repetition (A.I.R.) learning model is better than conventional learning in class VIII MTsN 3 Lima Puluh Kota.

Abstract

This study aims to explore the positive effect of using Learner Worksheets (LKPD) on motivation to learn mathematics on quadratic function material in class IX at MTsN 11 Agam. Math learning motivation is a key factor in improving students' academic performance and strengthening their understanding of complex mathematical concepts. This research is a quantitative descriptive research. The population in this study were ninth grade students at MTsN 11 Agam with a sample of 50 students. The collection technique used a Likert scale questionnaire by calculating the average percentage score of each indicator. The results of this study indicate that the use of LKPD on quadratic function material has a significant positive impact on students' motivation to learn mathematics. This confirms that LKPD can be an effective tool in triggering students' motivation to understand and master mathematical concepts, especially in material that is considered difficult such as quadratic functions. This is because there is an increase in the average learning motivation from before using LKPD of 58,60% to 78,30% after using LKPD. LKPD is also categorized as good for its feasibility as indicated by the average student response for each indicastor in the interval 70 < x ≤ 85. This research provides valuable insights into the important role of LKPD in increasing students' motivation to learn mathematics. The results of this study can be used as a foundation for the development of

Abstract

The aim of this study is to describe the level of motivation to learn mathematics among Year 8 pupils at SMPN 29 Padang in the 2024/2025 academic year. This study employed a quantitative descriptive approach with a sample comprising all Year 8 students. Data collection was conducted through the distribution of a mathematics learning motivation questionnaire designed based on indicators of intrinsic and extrinsic motivation, supplemented by documentation as supporting data. The data obtained were analysed using descriptive analysis techniques, calculating the percentage for each motivation indicator to determine the category of students’ learning motivation levels. The results of the analysis indicate that students’ motivation to learn mathematics falls into the high category, with a percentage of 67.55%. The difference in percentages between the intrinsic and extrinsic motivation indicators was not particularly significant, indicating that the influence of internal and environmental factors on students’ learning motivation was relatively balanced. An increase in both types of motivation has the potential to drive mathematics learning motivation into a higher category, thereby having a positive impact on learning outcomes and students’ interest in mathematics learning.

Abstract

The rainbow connection number is a graph parameter that integrates edge colouring and graph connectivity. A connected graph is said to be rainbow connected if every pair of vertices is joined by a path whose edges have distinct colours, and the rainbow connection number represents the minimum number of colours required to satisfy this property. This study aims to provide a comprehensive and systematic analysis of research developments related to rainbow connection numbers in graphs. The method employed is a systematic literature review of reputable international journals and nationally accredited publications. The analysis covers fundamental definitions, known values for various classes of graphs, relationships with structural parameters such as diameter, minimum degree, and connectivity, as well as computational complexity and several important variants, including strong rainbow connection, rainbow vertex-connection, and total rainbow connection. The results indicate that the rainbow connection number is strongly influenced by graph structure, with diameter serving as a natural lower bound and connectivity contributing to tighter upper bounds. Furthermore, determining the exact value for general graphs is computationally intractable, motivating the use of approximation and heuristic approaches. This study also identifies research gaps, particularly in algorithmic development and the analysis of complex graph class, and highlights potential applications in communication networks and network security.
