Mathematics anxiety is a psychological obstacle that consistently decreases students' motivation and learning achievement, especially at the junior high school level. This study aims to analyze the influence of the Integrated ADLX Introflex model on mathematics learning outcomes and mathematical anxiety of junior high school students in Bandar Lampung. The study used a quantitative approach with a Quasi-Experimental Pretest-Posttest Control Group design, involving 79 students in grade VIII divided into 38 students in the experimental class and 41 students in the control class. The instruments used included a learning achievement test (α = 0.87) and a mathematical anxiety questionnaire (α = 0.89). The data were analyzed using MANOVA after the assumption of normality and homogeneity was met. Partial test results showed F = 56.907 (η² = 0.428) for learning achievement and F = 25.889 (η² = 0.254) for anxiety, both significant at p = 0.000. The MANOVA test yielded Pillai's Trace = 0.522 with p = 0.000, proving that the model had a simultaneous effect on both variables. This model is proven to integrate cognitive, affective, and spiritual dimensions holistically. It is recommended to replicate at different levels and triangulate anxiety instruments psychophysiologically to strengthen the validity of further research.

The low mathematical problem-solving ability of students, as reflected in the PISA and National Assessment results, highlights the need for effective instructional models such as the LAPS-Heuristic with Time Token Arends to develop these skills. This study aims to compare students' mathematical problem-solving abilities between the LAPS-Heuristic-Time Token and Direct Instruction models, analyze the interaction between instructional models and conceptual tempo cognitive styles, and evaluate the differences in abilities based on cognitive styles using the LAPS-Heuristic-Time Token model. Using a quantitative approach with a factorial design experiment method, data were collected from the MFFT and problem-solving ability tests, analyzed using ANOVA. The results indicate that: (1) there is no significant interaction between instructional models and cognitive styles, (2) the LAPS-Heuristic-Time Token model is more effective than Direct Instruction, and (3) there are differences in problem-solving abilities based on cognitive styles. Reflective and quick students adapt well to both models, impulsive students perform better with Direct Instruction, while slow students are better suited to the LAPS-Heuristic-Time Token model. Additional interventions are needed to support impulsive and slow students according to their characteristics.

This study aims to describe students' mathematical reasoning abilities in the subject of Two-Variable Linear Inequality Systems (SPtLDV). This study was conducted because many students still have difficulty understanding the concepts and steps for solving SPtLDV, especially in understanding the relationship between variables and drawing logical conclusions from a mathematical problem. These difficulties often arise when students have to interpret mathematical statements into inequalities and describe the solution area on a coordinate plane. This study used a qualitative descriptive method with 14 students from class XI of SMA Negeri 12 Bandar Lampung as subjects. Data were collected through mathematical reasoning ability tests and interviews to explore the students' thinking processes. The results show that students' mathematical reasoning abilities vary. High-ability students are able to meet all reasoning indicators, from making assumptions, performing mathematical manipulations, providing reasons for solutions, to drawing correct conclusions. Students with moderate abilities were still lacking in writing down the steps of manipulation systematically and tended to make small errors in calculations. Meanwhile, students with low abilities had difficulty understanding basic concepts and often made mistakes in manipulating the variables x and y, resulting in inaccurate solutions. Penelitian ini bertujuan untuk menggambarkan kemampuan penalaran matematis siswa dalam mata pelajaran Sistem Ketidaksetaraan Linear Dua Variabel (SPtLDV). Penelitian ini dilakukan karena banyak siswa masih mengalami kesulitan dalam memahami konsep dan langkah-langkah penyelesaian SPtLDV, terutama dalam memahami hubungan antara variabel dan menarik kesimpulan logis dari suatu masalah matematis. Kesulitan ini sering muncul ketika siswa harus menginterpretasikan pernyataan matematis menjadi ketidaksetaraan dan menggambarkan daerah penyelesaian pada bidang koordinat. Penelitian ini menggunakan metode deskriptif kualitatif dengan 14 siswa kelas XI SMA Negeri 12 Bandar Lampung sebagai subjek. Data dikumpulkan melalui tes kemampuan penalaran matematis dan wawancara untuk mengeksplorasi proses berpikir siswa. Hasil menunjukkan bahwa kemampuan penalaran matematis siswa bervariasi. Siswa dengan kemampuan tinggi mampu memenuhi semua indikator penalaran, mulai dari membuat asumsi, melakukan manipulasi matematis, memberikan alasan untuk solusi, hingga menarik kesimpulan yang benar. Siswa dengan kemampuan sedang masih kurang dalam mencatat langkah-langkah manipulasi secara sistematis dan cenderung membuat kesalahan kecil dalam perhitungan. Sementara itu, siswa dengan kemampuan rendah mengalami kesulitan memahami konsep dasar dan sering membuat kesalahan dalam memanipulasi variabel x dan y, yang mengakibatkan solusi yang tidak akurat.

Mathematics learning on integer topics often faces challenges, such as low learning outcomes due to abstract teaching methods and limited student engagement. To address this, interactive digital learning media like Mathigon may be used. This quasi-experimental study aims to assess the impact of Mathigon media on students' mathematics learning outcomes in integer operations. The study used a nonequivalent control group design with 64 seventh-grade students selected through purposive sampling. One class (n=32) was assigned as the experimental group, receiving instruction using Mathigon media, while the control group (n=32) was taught using traditional methods. A validated learning outcomes test was used as the instrument. The results, analyzed using an independent sample t-test, indicated a significant difference in learning outcomes between the experimental and control groups (p<0.05). The experimental group had an average score of 75.71, while the control group had an average of 65.00. Thus, Mathigon media significantly improved students' learning outcomes on integer topics. Pembelajaran matematika pada materi bilangan bulat masih menghadapi berbagai tantangan, seperti rendahnya hasil belajar siswa akibat metode pembelajaran yang abstrak dan keterbatasan keterlibatan siswa. Salah satu solusi untuk mengatasi permasalahan ini adalah dengan menggunakan media pembelajaran digital interaktif seperti Mathigon. Penelitian kuasi-eksperimental ini bertujuan untuk menilai pengaruh penggunaan media Mathigon terhadap hasil belajar matematika siswa pada materi operasi bilangan bulat. Penelitian ini menggunakan desain kelompok kontrol pretest-posttest yang tidak setara dengan sampel sebanyak 64 siswa kelas VII yang dipilih menggunakan purposive sampling. Satu kelas (n=32) dijadikan sebagai kelompok eksperimen yang diajarkan menggunakan media Mathigon, sedangkan kelompok kontrol (n=32) menggunakan metode pembelajaran tradisional. Instrumen yang digunakan adalah tes hasil belajar yang telah divalidasi. Hasil analisis menggunakan uji t sampel independen menunjukkan adanya perbedaan signifikan pada hasil belajar antara kelompok eksperimen dan kelompok kontrol (p<0.05). Rata-rata hasil belajar kelompok eksperimen adalah 75,71, sementara kelompok kontrol 65,00. Dengan demikian, dapat disimpulkan bahwa media pembelajaran Mathigon memiliki pengaruh signifikan terhadap hasil belajar matematika siswa pada materi operasi bilangan bulat.

This study was conducted to address the low level of students’ mathematical communication skills in learning mathematics. It aimed to develop a game-based mathematics learning media using Educaplay integrated with the Contextual Teaching and Learning (CTL) approach to improve students’ mathematical communication skills on relations and functions material. The research was carried out at a junior high school involving 28 eighth-grade students. This study employed a Research and Development (R&D) method using the ADDIE model. Data were collected through expert validation sheets, student response questionnaires, and mathematical communication skill tests (pre-test and post-test).The results showed that the developed media was valid and feasible to use. The effectiveness test indicated an I ncrease in students’ average score from 51.92 in the pre-test to 76.82 in the post-test, with an N-Gain score of 0.56 (moderate category). This improvement reflects a moderate increase in students’ mathematical communication skills, particularly in visual representation and mathematical expression indicators. However, the improvement in written communication skills was relatively lower.These findings suggest that Educaplay-based learning media with the CTL approach is effective in improving students’ mathematical communication skills, although further development is needed to optimize written communication aspects. Penelitian ini dilatarbelakangi oleh rendahnya kemampuan komunikasi matematis peserta didik dalam pembelajaran matematika. Penelitian ini bertujuan untuk mengembangkan media pembelajaran matematika berbasis game Educaplay yang terintegrasi dengan pendekatan Contextual Teaching and Learning (CTL) guna meningkatkan kemampuan komunikasi matematis peserta didik pada materi relasi dan fungsi. Penelitian dilaksanakan di salah satu SMP dengan melibatkan 28 peserta didik kelas VIII. Metode yang digunakan adalah Research and Development (R&D) dengan model ADDIE. Teknik pengumpulan data meliputi lembar validasi ahli, angket respons peserta didik, serta tes kemampuan komunikasi matematis (pre-test dan post-test). Hasil penelitian menunjukkan bahwa media yang dikembangkan dinyatakan valid dan layak digunakan. Uji efektivitas menunjukkan adanya peningkatan rata-rata nilai peserta didik dari 51,92 pada pre-test menjadi 76,82 pada post-test dengan nilai N-Gain sebesar 0,56 yang termasuk kategori sedang. Peningkatan tersebut menunjukkan adanya peningkatan kemampuan komunikasi matematis peserta didik pada kategori sedang, terutama pada indikator representasi visual dan ekspresi matematis. Namun, peningkatan pada aspek komunikasi tertulis masih relatif lebih rendah. Dengan demikian, media pembelajaran berbasis Educaplay dengan pendekatan Contextual Teaching and Learning (CTL) cukup efektif dalam meningkatkan kemampuan komunikasi matematis peserta didik, meskipun masih diperlukan pengembangan lebih lanjut untuk mengoptimalkan aspek komunikasi tertulis.
