Abstract

Disposisi matematis merupakan objek kajian psikologi yang ditunjukkan dalam bentuk kecenderungn sikap, keyakinan, penilaian dan tindakan peserta didik terhadap matematika maupun hal yang berkaitan dengan matematika. Pengukuran disposisi matematis menggunakan instrumen angket skala likert dengan luaran berupa data ordinal. Data ordinal tidak memiliki linearitas pada skalanya sehingga jika digunakan dalam analisis statistik akan menghasilkan generalisasi yang tidak akurat. Salah satu model analisis data yang dapat menginterpretasikan data ordinal ke data interval dikenal dengan nama Model Rasch. Penelitian ini bertujuan untuk mendeskripsikan profil disposisi matematis yang dimiliki mahasiswa pada Program Studi Pendidikan Matematika UMRAH. Subjek yang diteliti adalah 65 orang mahasiswa Prodi Pendidikan Matematika UMRAH pada kelas Kalkulus Integral Tahun Ajaran 2019/2020. Instrumen penelitian menggunakan angket disposisi matematis MDFI yang berisi 60 butir pernyataan. Namun, data item yang dianalisis hanya berjumlah 58 item. Hal ini dikarenakan item i15 merupakan pernyataan negatif dari item i52 dan item i55 merupakan pernyataan ulang dari item i20. Analisis data menggunakan model analisis Rasch. Hasil penelitian menunjukkan 51,6% responden memiliki disposisi matematis sedang, 40,3% responden memiliki disposisi matematis tinggi dan 8,1% responden memiliki disposisi sangat tinggi. Nilai rata-rata disposisi matematis antara pria dan wanita tidak memiliki perbedaan yang signifikan.

Abstract

This study aims to produce teaching materials in the Geometry of Plane and Space course integrated with the maritime context of the Riau Islands. This research is a solution to problems arising from a need for teaching materials to the characteristics of students in the Mathematics Education Department of UMRAH. The 4D model (Define, Design, Development, and Disseminate) is used as the research development model. The research has reached the final activity of the Development stage, namely the practicality test of textbooks produced. The instrument used in the practicality test is a practicality questionnaire with a Likert scale. The evaluation results show that the textbooks produced through this development research have met the applicable criteria for use as teaching materials, with an achievement level of 72,85%. Thus, the textbook produced with the title Plane and Space Geometry Textbook has met the practical to use as teaching material in the Geometry of Plane and Space course. Integrating the maritime context of the Riau Islands helps students connect the content of teaching materials with their daily life. It helps them more easily understand the new knowledge.

Abstract

Students' mathematical problem-solving skills remain a critical challenge in junior high school education, with only 5% of students able to solve problems effectively. This difficulty is compounded by abstract learning materials and a lack of engaging, culturally relevant learning media. This research project aims to develop an adventure game learning medium set in the context of Maritime Malay culture to enhance junior high school students' mathematical problem-solving abilities. The purpose of this study is to determine the validity, practicality, and effectiveness of the learning media. This study employed the ADDIE research method, consisting of five stages: analysis, design, development, implementation, and evaluation. The subjects of this study were 35 eighth-grade students from SMP Negeri 1 Tanjungpinang. The instruments used were validation, practicality, and media effectiveness sheets. Data analysis techniques use both qualitative and quantitative methods. The material expert validation results showed an average assessment of 85.6%, indicating very valid criteria. The practicality results from the student-teacher trial showed 86.5% practicality, with very practical criteria. Furthermore, the product's effectiveness, measured using the N-Gain score, obtained a value of 0.61. Based on the data obtained, adventure games with a maritime Malay cultural context that improve mathematical problem-solving skills in junior high school students meet the criteria of validity, practicality, and effectiveness, making them suitable for use as learning media in the mathematics learning process.
