Abstract

This research notes that there is still a lack of focus on implementing digital-based learning media to helo students in understanding of the concept of Linear Equations with One Variable and in finding the solution in one of the East Nusa Tenggara (NTT) State Middle Schools. Virtual balance models can be used to help students learn the concept of linear equations. Therefore, this study aims to develop digital-based learning media, considering the quality criteria of being valid, practical, and effective. The research adopts the Research and Development (R&D) methodology with the ADDIE model (Analyze, Design, Development, Implementation, Evaluation). The research subjects are six seventh-grade students from one of the State Junior High Schools in East Nusa Tenggara with high, moderate, and low cognitive abilities. Data on the quality of learning media are obtained through questionnaires, interviews, and learning outcome tests. The learning media is categorized as highly valid with a percentage of 88% and highly practical with a percentage of 94%. Additionally, the learning media is deemed effective, with over 80% of the research subjects scoring above the Minimum Completion Criteria (KKM). Digital-based learning media utilizing the balance model feature in Mathigon with the help of Google Sites, was developed to facilitate students' understanding of concepts at one of the State Middle Schools in NTT. The problems presented in the media carry the culture that exists in the NTT region. Thus, students can easily imagine these problems because they are close to their lives. Both teachers and students feel assisted by the developed learning media. Using this media, teachers enable to monitor the students' progress and students also can participate actively during this learning. Penelitian ini mencatat bahwa masih kurangnya fokus pada implementasi media pembelajaran berbasis digital untuk membantu siswa dalam memahami konsep Persamaan Linear Satu Variabel (PLSV) dan penyelesaiannya di salah satu SMP Negeri Nusa Tenggara Timur (NTT).  Model keseimbangan virtual dapat dimanfaatkan untuk membantu siswa dalam mempelajari konsep persamaan linear.  Oleh karena itu, penelitian ini bertujuan untuk mengembangkan media pembelajaran berbasis digital pada materi persamaan linear satu variabel dengan memperhatkan kualitas yaitu valid, praktis dan efektif. Penelitian ini menggunakan jenis penelitian dan pengembangan atau Research and Development (R&D) dengan model ADDIE (Analyze, Design, Development, Implementation, Evaluation). Subjek penelitian adalah enam peserta didik kelas VII di salah satu SMP Negeri Nusa Tenggara Timur dengan kemampuan kognitif tinggi, sedang dan rendah. Data kualitas media pembelajaran diperoleh dari kuesioner, wawancara dan tes hasil belajar. Media pembelajaran dikategorikan sangat valid dengan persentase 88% dan sangat praktis dengan persentase 94%. Serta media pembelajaran juga dikatakan efektif, lebih dari 80% subjek penelitian mendapatkan nilai diatas Kriteria Ketuntasan Minimal (KKM). Media pembelajaran berbasis digital dengan memanfaatkan fitur model keseimbangan pada Mathigon berbantu Google Sites, dikembangkan untuk memfasilitasi pemahaman konsep siswa di salah satu SMP Negeri di NTT. Permasalahan yang disajikan dalam media tersebut, mengusung budaya yang ada pada daerah NTT. Sehingga siswa dapat dengan mudah membayangkan permasalahan tersebut karena dekat dengan kehidupan mereka. Guru dan peserta didik merasa terbantu dengan media pembelajaran yang telah dikembangkan. Guru dapat memonitoring perkembangan siswa dan siswa melalui media ini dapat terlibat aktif dalam pembelajaran.

Abstract

algebra is a fundamental topic in mathematics, particularly emphasized during the junior high school years as an essential subject. In the context of linear equations in one variable, students often struggle with obstacles in basic algebra including variable degrees, variable concepts, coefficients, and constants. However, proficiency in understanding algebraic concepts is significantly lower compared to other areas and skills. As a consequence, this research aimed to explore students' learning obstacles in solving linear equations in one variable in secondary schools based on mathematical proficiency. The research design using the hermeneutic phenomenological approach. This research is a framework of the Didactical Design Research (DDR). DDR is based on two paradigms: the interpretive and the critical paradigms, and it aims to empower students in the context of generating new knowledge as justified true belief. In this study, the researcher delves into the interpretive paradigm. The research subjects involved 46 seventh-grade secondary school students from five different schools across four distinct provinces in Indonesia. The instruments used were test and non-test. The test was done by giving a diagnostic test about linear equation problems, while interviews used the non-test technique. The data collected were analyzed using the Miles and Huberman model, namely data reduction, data presentation, and drawing conclusions. The study findings revealed that students met three types of obstacles in linear equation material, namely ontogenic obstacle, epistemological obstacle and didactical obstacle. However, students faced limited knowledge to solve mathematics problems in one variable, for instance, solving mathematical operations and making modelling problems from real situations deal with linear equations in one variable. Therefore, future research can focus on developing a Didactical Design to reduce this obstacle.

Abstract

Some students find trigonometric ratios challenging. Research on the application of Local Instruction Theory (LIT) in trigonometry is limited, particularly in secondary school understanding of trigonometric ratios. This study aims to develop an LIT for trigonometric ratios using Realistic Mathematics Education (RME). The researcher designed a learning pathway to help students grasp the fundamental concepts of trigonometric ratios. The study employs a research design methodology, developing a Hypothetical Learning Trajectory (HLT) to improve students' understanding. The development of LIT for Trigonometric Ratios follows three stages: initial design, teaching experiments, and retrospective analysis. Students demonstrated the ability to understand trigonometric ratios through the learning process. The findings suggest that the use of LIT-based instructional materials, incorporating RME principles, significantly enhances students' conceptual understanding of trigonometric ratios in high school. Beberapa siswa menganggap materi perbandingan trigonometri cukup sulit. Penelitian tentang penerapan Local Instruction Theory (LIT) dalam pembelajaran trigonometri masih sangat terbatas, khususnya terkait dengan pemahaman rasio trigonometri di sekolah menengah. Penelitian ini bertujuan untuk mengembangkan Local Instruction Theory (LIT) perbandingan trigonometri dengan menggunakan Realistic Mathematic Education (RME). Dalam upaya membantu siswa membangun konsep dasar pada materi perbandingan trigonometri, peneliti mengembangkan alur LIT dengan menemukan jalur pembelajaran yang efektif. Pencapaian tujuan penelitian menggunakan desain penelitian. Serangkaian kegiatan mengembangkan Hypothetical Learning Trajectory (HLT) sehingga siswa sekolah menengah atas (SMA) memiliki pemahaman yang lebih baik tentang perbandingan trigonometri. Pengembangan Local Instruction Theory untuk Perbandingan Trigonometri meliputi tiga tahap yaitu mengembangkan desain awal, melakukan percobaan pengajaran, dan melaksanakan analisis retrospektif.

The numeracy abilities of students in Indonesia are still considered inadequate or quite low and must continue to be improved. One of the efforts made to improve students' numeracy abilities is by implementing learning tools that can support the development of these abilities. The research aims to develop learning tools that can be declared valid, practical, and effective, especially in social arithmetic material, and improve students' numeracy skills. This research is development research with the 4D model from Thiagarajan. Thiagarajan's 4D stages include the definition, design, development, and deployment stages. The data collection techniques used are observation, questionnaires, and tests. The research results on developing Islamic boarding school-based learning tools are classified as valid, practical, and effective. The level of validity can be seen from the validation value: for the teaching module, it is 3.47; LKPD is 3.44; for the learning achievement test, it is 3.32; and the manual is 3.31 (maximum score 4), which is included in the valid category. The practicality value obtained from the students' activities was 90.7%, which was in the very good category; the implementation of learning was 3.56, which means high value; as well as the students' response questionnaire showed a positive value. The effectiveness value seen from the students' learning outcomes data was obtained at 87.0% classical completion. Not only that, but effectiveness can also be seen from the students' numeracy ability test, namely the results pre-test, which was an average of 34.87% increase in revenue post-test to 82.0%, which was then analyzed using the N-Gain test to obtain an average result of 0.73 which was included in the high category. Thus, Islamic boarding school-based learning tools on social arithmetic material can effectively be used to improve students' numeracy skills. Kemampuan numerasi peserta didik di Indonesia masih tergolong kurang atau cukup rendah dan masih harus terus ditingkatkan. Salah satu upaya yang dilakukan untuk meningkatkan kemampuan numerasi peserta didik adalah dengan menerapkan perangkat pembelajaran yang dapat menunjang berkembangnya kemampuan tersebut. Adapun penelitian yang dilakukan ini memiliki tujuan untuk mengembangkan perangkat pembelajaran yang dapat dinyatakan valid, praktis, dan efektif, khususnya pada materi aritmatika sosial serta mampu meningkatkan kemampuan numerasi santri.

Abstract

Mathematical reasoning ability is one of the most important parts of mathematics learning. However, the facts show that students' mathematical reasoning ability is still low, especially in the context of the Pythagorean theorem. One attempt to facilitate this is using students' worksheets based on creative problem solving (CPS). This research aims to develop valid and practical student' worksheets. It refers to the 4D development model, which includes defining, designing, developing, and disseminating. The instruments used are validation and practicality questionnaire sheets. The results of the validity assessment of students' worksheets were very valid, with an average percentage of 95,07%. The results of the practicality assessment of students' worksheets were very practical, with an average rate of 89,38%. Thus, it is in accord with the valid and practical requirements, so the worksheet is usable. This research aims to make it easier for students to build knowledge independently in mathematics learning so that mathematical reasoning abilities can be facilitated. Kemampuan penalaran matematis (KPM) menjadi salah satu aspek yang terpenting dalam pembelajaran matematika, namun fakta menunjukkan KPM peserta didik masih rendah khususnya pada konten teorema Pythagoras. Salah satu upaya untuk memfasilitasi masalah tersebut dengan menggunakan Lembar kerja peserta didik (LEMBAR KERJA SISWA) berbasis Creative Problem Solving (CPS). Tujuan penelitian ini adalah mengembangkan LEMBAR KERJA SISWA yang valid dan praktis. Penelitian pengembangan ini mengacu pada model pengembangan 4D yang meliputi define, design, develop, dan disseminate. Instrumen yang digunakan adalah angket validasi dan angket praktikalitas. Hasil analisis data angket validasi diperoleh bahwa LEMBAR KERJA SISWA dikategorikan sangat valid dengan persentase rata-rata yaitu 95,07%. Hasil analisis data angket praktikalitas diperoleh bahwa LEMBAR KERJA SISWA dikategorikan sangat praktis dengan persentase rata-rata yaitu 89,38%. Maka, LEMBAR KERJA SISWA pada penelitian ini telah memenuhi syarat valid dan praktis sehingga dapat digunakan dalam kegiatan pembelajaran. Implikasi dari penelitian ini adalah untuk mempermudah peserta didik dalam membangun pengetahuan secara mandiri pada pembelajaran matematika sehingga kemampuan penalaran matematis dapat terfasilitasi.

Abstract

Computational thinking and problem-solving skills are necessary for the future careers of pre-service mathematics teacher students in the 21st century. This study aims to analyse problem-solving activities in geometry teaching and corresponding assessment for pre-service mathematics teacher students from a computational thinking perspective. To do so, we carried out a qualitative case study through teaching and learning observations involving 41 pre-service mathematics teacher students from one of the state universities in West Java, Indonesia. In this study, 6 x 50 minutes of geometry teaching were observed, and written work containing problem-solving processes retrieved from the formative assessment was analysed from the computational thinking perspective. The results showed that two types of problem-solving activities are identified from the teaching and learning processes and the corresponding assessment, i.e., problem to find and problem to prove. We view that a problem to prove can typically be considered as a structured problem to find. Both types of problems can be fruitfully analysed using Polya’s problem-solving strategy from the computational thinking perspective. For future research, we recommend investigating each type of problem using more specific characteristics of computational thinking. Keterampilan berpikir komputasi (computational thinking)  dan pemecahan masalah diperlukan untuk karir masa depan mahasiswa calon guru matematika di abad ke-21. Penelitian ini bertujuan untuk menganalisis aktivitas pemecahan masalah dalam proses pembelajaran geometri dan asesmennya untuk mahasiswa calon guru matematika dari perspektif berpikir komputasi. Untuk itu, kami melakukan studi kasus kualitatif melalui observasi proses pembelajaran yang melibatkan 41 mahasiswa calon guru matematika dari salah satu universitas negeri di Jawa Barat, Indonesia. Dalam penelitian ini, kami mengobservasi pembelajaran geometri untuk calon guru matematika selama 6 x 50 menit, dan hasil tes tertulisnya yang berisi proses pemecahan masalah yang dianalisis dari perspektif berpikir komputasi. Hasil penelitian menemukan adanya dua jenis tipe pemecahan masalah, yang diidentifikasi dari pengamatan proses pembelajaran dan penilaian formative, yaitu masalah tipe menemukan dan masalah tipe membuktikan. Kami memandang bahwa masalah tipe membuktikan sebagai masalah terstruktur dari tipe menemukan. Kedua tipe masalah tersebut dapat dianalisis dengan baik menggunakan strategi pemecahan masalah Polya dari perspektif berpikir komputasi. Untuk penelitian mendatang, kami merekomendasikan untuk menelaah lebih lanjut setiap tipe masalah dengan menggunakan karakteristik berpikir komputasi yang lebih spesifik.

Abstract

Despite extensive research on mathematics within universities, yet exploration of alternative solutions for challenges students faced during mathematics lectures was limited. Particularly, integrating mobile technology assistance via didactical design research received little attention. Therefore, researchers tried to describe the role of mobile technology in supporting mathematics lectures at an Indonesian university. Didactic design research was the method used in this research. Participants comprised 53 students aged 18–25 years. The main research tools included the researcher, a math comprehension test, an in-depth interview guide, and a hybrid mathematics module with mobile technology support. Thematic analysis uncovered learning barriers, while lecture data underwent qualitative and retrospective analysis. The findings were low mastery of prerequisites, carelessness, and a limited context for lecture. The hybrid module was able to minimize mathematics student learning obstacles in higher education. This research recommends lecturers facilitate problem-based activities with mobile technology to enhance students competencies in higher education. Cukup banyak penelitian yang mengkaji matematika di universitas, tetapi eksplorasi mengenai solusi alternatif terhadap tantangan yang dihadapi mahasiswa selama kuliah matematika masih terbatas. Khususnya, pengintegrasian teknologi seluler melalui penelitian desain didaktis kurang mendapat perhatian. Oleh karena itu, penelitian ini mencoba untuk mendeskripsikan peran teknologi seluler dalam mendukung kuliah matematika pada sebuah universitas di Indonesia. Didactical design research merupakan metode yang digunakan dalam penelitian ini. Pertisipan terdiri dari 53 mahasiswa berusia 18–25 tahun. Instrumen utama adalah peneliti, tes pemahaman matematika, panduan wawancara mendalam, dan modul matematika hibrida dengan dukungan teknologi seluler. Analisis tematik digunakan untuk mengkaji hambatan belajar, sementara data perkuliahan dianalisis menggunakan kombinasi antara analisis kualitatif dan retrospektif. Temuan penelitian ini adalah penguasaan prasyarat yang rendah, kecerobohan, dan konteks perkuliahan yang terbatas. Modul hibrida mampu meminimalkan hambatan belajar mahasiswa matematika di pendidikan tinggi. Penelitian ini merekomendasikan kepada dosen untuk memfasilitasi kegiatan berbasis masalah dengan teknologi seluler untuk meningkatkan kompetensi mahasiswa di pendidikan tinggi.

Abstract

This study identified students' mathematical understanding and communication deficiencies, especially in dividing numbers. Although bowls and marbles have been used to support mathematical conceptual understanding, there are limitations in understanding how students communicate effectively about division and numbers in practical contexts. This study explores students' mathematical communication skills in dividing and counting and how using bowls and marbles influences this. The research method used is a case study with a qualitative approach involving direct observation and video recording. The study subjects comprised four students with mild intellectual disabilities and different characteristics in communicating and understanding mathematical concepts. The instruments used included observation notes and video recordings of learning. Data were collected through observation of the learning process and video analysis to assess communication skills and conceptual understanding. The results showed that students 1 and 2 had better mathematical communication skills and a strong understanding of division, although with some initial errors. Students 3 and 4 highly depended on teacher direction and were less active in verbal communication. This study concludes that using bowls and marbles can improve understanding of division, but the success of mathematical communication is greatly influenced by active student involvement and teacher direction. This study implies the need to develop more interactive learning strategies and additional support for students with difficulties in mathematical communication. Applying teaching techniques emphasizing active student involvement and effective use of bowls and marbles can improve understanding of mathematical concepts and communication skills. Penelitian ini mengidentifikasi kekurangan dalam pemahaman dan komunikasi matematis siswa, terutama dalam konteks pembagian bilangan. Meskipun bowls and marbles telah digunakan untuk mendukung pemahaman konsep matematis, terdapat keterbatasan dalam memahami bagaimana siswa berkomunikasi secara efektif mengenai pembagian dan membilang dalam konteks praktis. Penelitian ini bertujuan untuk mengeksplorasi kemampuan komunikasi matematis siswa dalam konteks pembagian dan membilang serta bagaimana hal ini dipengaruhi oleh penggunaan mangkok dan kelereng. Metode penelitian yang digunakan adalah studi kasus dengan pendekatan kualitatif, melibatkan observasi langsung dan rekaman video. Subjek penelitian terdiri dari empat siswa tunagrahita ringan dengan karakteristik berbeda dalam berkomunikasi dan memahami konsep matematika. Instrumen yang digunakan meliputi catatan observasi dan rekaman video pembelajaran. Data dikumpulkan melalui observasi proses pembelajaran dan analisis video untuk menilai kemampuan komunikasi dan pemahaman konsep. Hasil penelitian menunjukkan bahwa siswa 1 dan siswa 2 memiliki kemampuan komunikasi matematis yang lebih baik dan pemahaman yang kuat mengenai pembagian, meskipun dengan beberapa kesalahan awal. Siswa 3 dan siswa 4 menunjukkan ketergantungan yang tinggi pada arahan guru dan kurang aktif dalam komunikasi verbal. Kesimpulan dari penelitian ini adalah bahwa media manipulatif dapat meningkatkan pemahaman pembagian, namun keberhasilan komunikasi matematis sangat dipengaruhi oleh keterlibatan aktif siswa dan arahan guru. Implikasi dari penelitian ini adalah perlunya pengembangan strategi pembelajaran yang lebih interaktif dan dukungan tambahan bagi siswa yang menunjukkan kesulitan dalam komunikasi matematis. Penerapan teknik pengajaran yang menekankan pada keterlibatan siswa secara aktif dan penggunaan media manipulatif yang efektif dapat meningkatkan pemahaman konsep matematis dan keterampilan komunikasi.

Abstract

This study reveals the potential of ChatGPT in supporting students' mathematics learning. However, the study's results also show challenges in utilising ChatGPT, such as inconsistent answer quality and potential student dependence on technology. This indicates the need for a more holistic approach to integrating ChatGPT into the learning process. This study aimed to analyse ChatGPT's ability to answer quantitative knowledge and mathematical reasoning questions, assess students' prompting abilities with ChatGPT, evaluate the use of ChatGPT, and measure the extent to which students' mathematical, creative and critical abilities have increased. This study uses an Embedded Design type of Mixed Method approach. The population in this study were all high school students who took the Tridaya Tutoring Program 2024/2025. The sampling technique used was purposive sampling, and the sample selected was all 20 students from class XII of Tridaya Tutoring High School. The research instruments used were written tests, namely multiple-choice questions and documentation studies of screenshots of ChatGPT answer results. The study results showed that the t value for measuring creative and critical abilities was 6.691 and 7.151. It was found that there was a significant difference between the test scores obtained before and after the treatment. This shows that the instructions given to students can improve their test scores. ChatGPT can help students in learning as a virtual tutor. However, it should also be noted that not all questions can be answered. Some even have different answers. This makes students dissatisfied with the results obtained. This is where students are trained in critical thinking why this can happen. In addition, the student's prompting technique for ChatGPT is also considered. There is a need for creativity in prompting so students can further explore the answers from ChatGPT. Although they can answer any question, guidance from the teacher and independent verification are needed regarding the answers given by ChatGPT so that the desired answer is by expectations. Penelitian ini mengungkap potensi ChatGPT dalam mendukung pembelajaran matematika siswa. Namun, hasil penelitian juga menunjukkan tantangan dalam memanfaatkan ChatGPT, seperti kualitas jawaban yang tidak konsisten dan potensi ketergantungan siswa pada teknologi. Hal ini menunjukkan perlunya pendekatan yang lebih holistik untuk mengintegrasikan ChatGPT ke dalam proses pembelajaran. Penelitian ini bertujuan untuk menganalisis kemampuan ChatGPT dalam menjawab pertanyaan pengetahuan kuantitatif dan penalaran matematika, menilai kemampuan prompting siswa dengan ChatGPT, mengevaluasi penggunaan ChatGPT, dan mengukur sejauh mana kemampuan matematika, kreatif, dan kritis siswa meningkat. Penelitian ini menggunakan pendekatan Mixed Method tipe Embedded Design. Populasi dalam penelitian ini adalah seluruh siswa SMA yang mengikuti Program Bimbingan Belajar Tridaya 2024/2025. Teknik pengambilan sampel yang digunakan adalah purposive sampling, dan sampel yang dipilih adalah seluruh siswa kelas XII SMA Bimbingan Belajar Tridaya yang berjumlah 20 orang. Instrumen penelitian yang digunakan adalah tes tertulis, yaitu soal pilihan ganda dan studi dokumentasi berupa tangkapan layar hasil jawaban ChatGPT. Hasil penelitian menunjukkan bahwa nilai t untuk mengukur kemampuan kreatif dan kritis adalah 6,691 dan 7,151. Ditemukan bahwa terdapat perbedaan yang signifikan antara nilai tes yang diperoleh sebelum dan sesudah perlakuan. Hal ini menunjukkan bahwa petunjuk yang diberikan kepada siswa dapat meningkatkan nilai tes mereka. ChatGPT dapat membantu siswa dalam belajar sebagai tutor virtual. Namun, perlu diperhatikan juga bahwa tidak semua soal dapat dijawab. Bahkan ada yang jawabannya berbeda-beda. Hal ini membuat siswa tidak puas dengan hasil yang diperoleh. Di sinilah siswa dilatih untuk berpikir kritis tentang mengapa hal tersebut dapat terjadi. Selain itu, teknik prompting siswa untuk ChatGPT juga diperhatikan. Perlu adanya kreativitas dalam prompting agar siswa dapat lebih mengeksplorasi jawaban dari ChatGPT. Meskipun dapat menjawab soal apa saja, diperlukan arahan dari guru dan verifikasi mandiri terkait jawaban yang diberikan ChatGPT agar jawaban yang diinginkan sesuai dengan harapan.
