In response to students’ persistent difficulties in understanding integer operations and the limited use of engaging digital game-based media in mathematics classrooms, this study aims to develop “Quick Count Math,” an educational game-based instructional medium on the topic of integers for seventh-grade junior high school students. The study employed a Research and Development (R&D) design using the Four-D model, which consists of the define, design, develop, and disseminate stages. The game is designed to support learning of integer operations (addition, subtraction, multiplication, and division) through interactive challenges, gradually increasing levels of difficulty, immediate feedback, and appealing visuals. The results indicate that “Quick Count Math” meets the criteria of validity, practicality, and effectiveness. Expert review yielded validity scores of 85% for media aspects and 100% for content aspects, both categorized as very high. In addition, the game was reported to be easy to use by students and was effective in improving their understanding and learning outcomes on the integer topic, with an effectiveness score of 86%. These findings suggest that “Quick Count Math” can serve as an engaging and effective alternative digital medium for teaching mathematics in seventh-grade junior high school classes and contribute to the literature on game-based mathematics learning by offering a validated design that can be adapted to other topics and grade levels.

Mathematics education in Indonesia, particularly in high schools, faces significant challenges in improving students' understanding of abstract concepts, especially in statistics. The lack of practical application and the focus on memorization of formulas hinder students' ability to relate mathematical concepts to real-life situations. To address these challenges, Project-Based Learning (PjBL) is proposed as an effective approach that engages students in real-world projects, encouraging active participation, critical thinking, and the application of mathematical concepts. This study employs the Research and Development (R&D) method with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation) to develop a Student Worksheet (LKPD) based on PjBL for teaching statistics in class XII at SMK Kesehatan Bulawan. The development process includes analyzing the curriculum, student characteristics, and learning goals, followed by designing, validating, and revising the LKPD. The product is then implemented in a small group trial and evaluated for its validity, practicality, and effectiveness through expert validation, practical questionnaires, and student learning tests. The LKPD received very high validity, with expert validation scores of 95% for content and 90% for design, resulting in an average score of 92.5%. Practicality assessments showed a 91.5% average, indicating the LKPD was easy to use by both teachers and students. The effectiveness of the LKPD was confirmed by an 80% average student achievement rate, with 80% of students meeting the KKM (Minimum Completeness Criteria). The developed LKPD based on PjBL is highly valid, practical, and effective for improving students' understanding of statistics, making it a suitable tool for enhancing mathematics education in SMK.

This study aims to identify whether the average learning outcomes of students who learn using the Collaborative Problem-Solving learning model are higher than the average learning outcomes of students who learn using the Direct learning model (lecture method) on the Two-Variable Linear Equation System material. This study uses a posttest-only control group design. The population of this study was all eighth-grade students and the sample in this study was class VIII-A as an experimental class consisting of 20 students and class VIII-B as a control class consisting of 10 students at SMP Negeri 3 Tondano in the even semester of the 2024/2025 academic year. The results revealed that there was a difference in the average learning outcomes of students taught using the Collaborative Problem-Solving learning model with students taught using the Direct learning model. Based on the above results, it can be concluded that using the Problem-Based Learning model can improve students' mathematics learning outcomes in the topic of Two-Variable Linear Equation Systems.

Pemahaman konsep matematika merupakan komponen penting dalam pembelajaran Sistem Persamaan Linear Dua Variabel (SPLDV) karena berperan dalam kemampuan siswa memecahkan masalah kontekstual. Penelitian ini bertujuan untuk menganalisis pemahaman konsep siswa berdasarkan teori APOS (Action, Process, Object, Schema) yang menguraikan tahapan berpikir matematis siswa. Studi ini menggunakan pendekatan kualitatif dengan teknik pengumpulan data melalui tes diagnostik dan wawancara mendalam terhadap tiga siswa yang mewakili kategori kemampuan tinggi, sedang, dan rendah dari total 28 siswa yang mengikuti tes. Hasil menunjukkan bahwa siswa berkemampuan tinggi mampu menyelesaikan soal SPLDV secara hampir menyeluruh berdasarkan tahapan APOS, meskipun terdapat kekurangan dalam representasi tertulis. Siswa berkemampuan sedang menunjukkan pemahaman terbatas, khususnya dalam menentukan metode penyelesaian dan menarik kesimpulan. Sementara itu, siswa berkemampuan rendah hanya menunjukkan pemahaman semu, karena jawaban diperoleh dari sumber eksternal tanpa melalui proses konstruksi pengetahuan. Temuan ini menegaskan efektivitas teori APOS sebagai kerangka analisis untuk mengidentifikasi kesulitan belajar matematika secara komprehensif. Penelitian ini memberikan kontribusi pada pengembangan strategi pembelajaran berbasis tahapan kognitif siswa dan menyarankan eksplorasi lanjutan dengan integrasi pendekatan teknologi. Kata kunci: pemahaman konsep matematika; teori APOS; SPLDV; pembelajaran kontekstual; kemampuan berpikir matematis Abstract: Conceptual understanding in mathematics is a critical component in learning Systems of Linear Equations in Two Variables (SPLDV), as it plays a significant role in students’ ability to solve contextual problems. This study aims to analyze students' conceptual understanding based on the APOS theory (Action, Process, Object, Schema), which outlines the stages of mathematical thinking. A qualitative approach was employed, involving diagnostic tests and in-depth interviews with three students representing high, moderate, and low ability levels, selectsed from a total of 28 students who participated in the test. The results revealed that the high-ability student was able to complete the SPLDV problems across nearly all APOS stages, although with some limitations in written representation. The moderate-ability student demonstrated partial understanding, especially in selecting problem-solving methods and drawing conclusions. Meanwhile, the low-ability student showed only surface-level understanding, as responses were obtained from external sources without internal knowledge construction. These findings affirm the effectiveness of the APOS theory as an analytical framework to identify learning difficulties in mathematics comprehensively. This research contributes to the development of instructional strategies based on students’ cognitive stages and suggests further exploration of the integration of technological approaches. Keywords: mathematics conceptual understanding; APOS theory; systems of linear equations; contextual learning; mathematical thinking skills

Based on the results of observations and interviews that have been conducted at SMP Negeri 1 Tondano, information was obtained that the learning process is still using the direct learning model. Where learning is only centered on the teacher, so students are less active in learning mathematics.This causes students to have grades that are standard or below average. This cen be seen from the average score of students, which is 67.5, while the Minimum Completeness Criteria (KKM) set in schools is 75. The purpose of this study is to determine whether the learning outcomes of students who use the cooperative learning model of the student teams achievement division type are higher from student learning outcomes using direct learning models on circle material. The experimental design used in this study was a posstest control group design. the sample of this study was class VIIIC as the experimental class with 28 students and class VIIIB as the control class with 29 students at SMP Negeri 1 Tondano. Data obtained from student learning outcomes tests. With the average student learning outcomes in the experimental class was 81.64 and the average student learning outcomes in the control class was 72.85. analysis of the data using the t-test with a value of ???????????????????????? = 1.902 > ???????????????????????? = 1,67 then reject ????0 and accept ????1. The results of the study concluded that student learning outcomes taught by cooperative learning model type student teams achievement division were higher than student learning outcomes taught using direct learning models, so that they were well applied to the process of learning activities.
