Abstract

Children at the Kasih Ibu orphanage require educational attention, particularly in mathematics. Without adequate guidance and support, they will struggle to grasp basic mathematical concepts. These fundamental mathematical concepts serve as the foundation for higher education. Guidance and support are essential for learning. The community service approach used is a participatory approach with a mentoring model. This service is divided into three stages: preparation, implementation, and evaluation. Observations during the mentoring process revealed a positive response in terms of participation, motivation, and participant responses. With the mentoring, participants demonstrated positive changes compared to before the mentoring.

Abstract

Geometri analitik bidang merupakan mata kuliah yang diwajibkan bagi mahasiswa semester III program studi TMT. Geometri analitik bidang lebih banyak diajarkan dengan ceramah tanpa pengaitan dengan kehidupan nyata. Padahal mata kuliah geometri analitik bidang banyak diaplikasikan dalam berbagai bidang seperti mesin, fisika, dan lain-lain. Penelitian ini bertujuan untuk mencari perbedaan pendekatan deep learning, kontektual learning, dan konvensional dengan menggunakan assesmen numerasi. Metode penelitian kuantitatif dengan jenis quasi eksperimen dan desain postest only with nonequivalent groups. Metode pengumpulan data menggunakan tes numerasi dengan analisis data one away anova. Hasil penelitian menunjukkan bahwa ada perbedaan hasil numerasi dari ketiga pendekatan. Pendekatan deep learning berbeda signifikan berdasarkan nilai mean dan p-value dibanding dengan pendekatan kontekstual dan konvensional.

Abstract

This research seeks to create legitimate and practical teaching materials in the form of a module utilizing a realistic mathematics education approach focused on the topic of systems of linear equations in two variables. This study utilizes the research and development (RD) approach, specifically the Thiagarajan 4-D model, which consists of four stages: (1) definition, (2) design, (3) development, and (4) dissemination. We conducted the research at MTsN 1 Central Aceh. Two classes, each with high and moderate abilities, participated in the research. The trial analysis yielded the following findings: (1) Validity, as two experts validated the teaching materials; (2) Practicality, as demonstrated by an average implementation of the learning syntax exceeding 75%, an average student activity exceeding 75%, extremely positive student and teacher responses to the module, and a classification of the developed module as practical. According to the results of the students' learning tests, 15 students completed the requirements out of 19 students in the high-ability class, and 14 students completed the requirements out of 19 students in the medium-ability class. Consequently, we categorize the percentage of students who have met the requirements as excellent. The module created utilizing a realistic mathematics education technique for the topic of systems of linear equations in two variables for eighth grade is deemed viable, indicating it is both valid and practical.
