“…They also have trouble converting problems into numerical forms and aren't used to following Polya's steps for the right way to solve problems. This is consistent with research conducted by (Riana & Fitrianna, 2021;Fitriana & Mampouw, 2019). On the third question's answer sheet, it was found that students still struggle with using variables, diagrams, and mathematical models to represent problems.…”

Literasi numerasi sebagai kemampuan memahami dan menggunakan konsep matematika dalam kehidupan sehari-hari, telah diakui sebagai salah satu kompetensi penting dalam era ini. Dalam konteks pendidikan formal, banyak siswa menghadapi tantangan dalam mengembangkan kemampuan literasi numerasinya, sehingga diperlukan adanya pengembangan instrumen yang berpotensi memberikan kontribusi penting yang kontekstual dan memperkaya pengalaman belajar literasi numerasi siswa. Tujuan dari penelitian ini adalah untuk menghasilkan produk pengembangan instrumen literasi numerasi berbasis kearifan lokal di Kabupaten Pandeglang bagi siswa kelas IX MTs dengan elemen materi pola bilangan, peluang, bangun ruang sisi datar dan aljabar. Penelitian ini termasuk dalam kategori penelitian pengembangan yang mengacu pada model penelitian formatif Tessmer. Subjek hingga di prototipe akhir pada penelitian ini adalah 38 orang siswa kelas IX di MTsN 2 Pandeglang. Instrumen yang digunakan untuk pengumpulan data adalah lembar validasi, pedoman wawancara dan soal tes instrumen literasi numerasi berbasis kearifan lokal Kabupaten Pandeglang. Metode analisis data yang digunakan adalah dengan mengevaluasi kesesuaian, kualitas dan akurasi instrumen yang dikembangkan melalui ahli dan analisis statistik. Hasil penelitian menunjukkan bahwa bahwa pertanyaan-pertanyaan yang dikembangkan memiliki tingkat validitas yang baik, meskipun masih memerlukan perbaikan berdasarkan saran dan umpan balik yang diberikan oleh validator, selanjutnya untuk kualitas tes yang dikembangkan diantaranya indeks kesukaran keempat soal berada pada kategori sedang, daya pembeda soal dapat diterima dengan baik dan valid serta memiliki realibilitas yang tinggi (0,93). Berdasarkan hasil penelitian tersebut, maka dapat disimpulkan instrumen literasi numerasi berbasis kearifan lokal di Kabupaten Pandeglang yang dikembangkan sudah layak untuk digunakan.Numeracy literacy, as the ability to understand and apply mathematical concepts in everyday life, has been recognized as a crucial competence in this era. In the context of formal education, many students face challenges in developing their numeracy literacy skills, thus necessitating the development of instruments that have the potential to contribute significantly by being contextual and enriching students' numeracy literacy learning experiences. The aim of this research is to produce a development product of a numeracy literacy instrument based on local wisdom in Pandeglang Regency for grade IX students at Madrasah Tsanawiyah, focusing on number patterns, probability, two-dimensional shapes, and algebraic elements. This research falls under the category of development research, referring to Tessmer's formative research model. The subjects up to the final prototype in this research are 38 students from class IX at MTsN 2 Pandeglang. The instruments used for data collection were validation sheets, interview guidelines, and a numeracy literacy test instrument based on local wisdom in Pandeglang Regency. The data analysis method used involved evaluating the suitability, quality, and accuracy of the developed instrument through expert judgment and statistical analysis. The research results indicate that the developed questions have a good level of validity, although they still require improvement based on the suggestions and feedback provided by the validators. Furthermore, in terms of the quality of the developed test, the difficulty index of the four items falls under the moderate category, the item discrimination is acceptable and valid, and the test exhibits high reliability (0.93). Based on these research results, it can be concluded that the developed numeracy literacy instrument based on local wisdom in Pandeglang Regency is suitable for use.

“…Based on the interview results, S1 was able to explain the calculation steps correctly and completely. (Fitriana & Mampouw, 2019) stated that students who have a high category of solving skills are able to work on problems using plans that have been prepared beforehand. In the review indicator, students can rewrite the answers obtained by writing the correct conclusion, namely diagonal 1, the space pattern of Sipirok's typical woven fabric in the shape of a rhombus, which is 16 cm.…”

The ability to solve problems is one of the goals of mathematics education. The aim of this study was to describe the problem-solving skill of students in class VII-1 of MTsL 3 Tapanuli Selatan on the material of the Plane figure with ethnomathematical nuances of Sipirok woven fabrics patterns. This qualitative descriptive research involved 25 students of class VII-1 MTsN 3 Tapanuli Selatan as the subjects. Data collection techniques included problem-solving skills tests and interview papers. The results showed that the student's problem-solving skills based on the steps Polya, flat geometric material with ethnomathematical nuances for class VII-I, belonged to the low category with an average percentage of 55.4% and the step indicator more dominant of the polya was an indicator understanding the problem with 80% capture.

Disposisi matematis adalah salah satu aspek afektif yang perlu diperhatikan dalam proses perkuliahan, sebab disposisi matematis juga dapat menunjang keberhasilan belajar dalam mengikuti perkuliahan. Penelitian ini dimaksudkan untuk mendeskripsikan disposisi matematis mahasiswa Pendidikan Matematika pada mata kuliah Kalkulus 1 di Universitas Negeri Gorontalo. Penelitian melibatkan mahasiswa pendidikan matematika yang berjumlah 47 orang. Instrumen yang digunakan adalah angket, yang didampingi dengan observasi partisipatif. Disposisi matematis dilihat dari 6 indikator yaitu: (1) Percaya diri; (2) Kegigihan dan Ketekunan; (3) Fleksibel; (4) Minat dan Keingintahuan; (5) Refleksi; (6) Apresiasi. Data dianalisis secara kuantitatif dalam bentuk persentase. Hasil penelitian menunjukkan rata-rata disposisi matematis mahasiswa sebesar 69,57% yakni dengan kategori sedang. Persentase jumlah mahasiswa program studi pendidikan matematika dengan tingkat disposisi matematis yang tinggi, sedang dan rendah berturut-turut adalah 14,89%, 68,09% dan 17,02%.Mathematical disposition is an affective aspect that needs to be developed and improved during lectures because mathematical disposition can support learning success in attending lectures. This study aims to describe the mathematical disposition of Mathematics Education students in the Calculus 1 course at the State University of Gorontalo. The subjects of this study were students of mathematics education, amounting to 47 students. The instrument used is a questionnaire, which is accompanied by participatory observation. To measure the mathematical disposition of mathematics education students in the calculus 1 course, it can be seen from 6 indicators, which are: (1) Confidence; (2) Persistence and Perseverance; (3) Flexible; (4) Interests and Curiosities; (5) Reflection; (6) Appreciation. Data were analyzed quantitatively in the form of percentages. The results showed that in general the average mathematical disposition of students was 69.57%, namely in the medium category. The percentages of students in the mathematics education study program who have high, medium, and low levels of mathematical disposition are 14.89%, 68.09%, and 17.02%, respectively.
