Abstract

Kemampuan numerasi merupakan dasar dari berbagai aspek kehidupan. Dalam pembelajaran, kemampuan numerasi tidak hanya dapat meningkatkan kemampuan kognitif dan problem solving, akan tetapi juga dapat mengembangkan kemampuan bernalar kritis siswa. Tujuan pengabdian ini yaitu untuk meningkatkan kemampuan numerasi siswa yang merupakan kemampuan dasar untuk mempelajari matematika yang tingkatannya lebih kompleks maupun pelajaran lainnya. Metode yang digunakan adalah Community Based Research (CBR) yaitu suatu pendekatan yang mengutamakan kebutuhan masyarakat dan menyatukan berbagai elemen komunitas untuk dapat berpartisipasi secara aktif dalam penelitian guna mengatasi tantangan yang muncul di dalam komunitas tersebut. Subjek dalam kegiatan ini adalah siswa kelas X SMA Cut Meutia Banda Aceh yang berjumlah 120 siswa. Hasil dari pengabdian ini menunjukkan peningkatan kemampuan numerasi siswa melalui tes yang diberikan setelah pelatihan berakhir dan adanya motivasi siswa untuk terus melatih kemampuan numerasi mereka yang diketahui melalui hasil angket.

Abstract

Geometry can be challenging for students due to its abstract nature; The difficulty is often associated with low spatial abilities; to overcome these challenges, educators can employ dynamic and visual learning approaches to help students learn and understand geometric concepts more effectively. This study aimed to develop a Geo Math application by integrating the GeoGebra applets on geometry that fulfill valid, practical, and effective aspects that are expected to improve spatial abilities. This research utilized development research using the ADDIE model, which consists of 5 stages: analysis, design, development, and trial implementation. It went through several trial stages consisting of validation experts, one-to-one trials, and small group trials, and the evaluation stage was carried out through a pre-post-test quasi-experimental study. Based on the results, it can be concluded that the Geo Math application was very feasible to support the implementation of learning mathematics, especially in learning geometric transformations, which could assist students in constructing concepts from various transformations effectively. The interactive and dynamic nature of GeoGebra applets within the application allowed students to visualize and manipulate geometric objects and could make abstract mathematical concepts more concrete and accessible, which could improve students’ spatial abilities.

Abstract

Learning loss is when a student loses academic knowledge and skills due to certain situations and conditions, such as pandemics, long school holidays, and other emergencies. An effort can be made to determine the learning loss that occurs in students by using diagnostic tests. However, the availability of questions for diagnostic tests on mathematics, especially trigonometry material, is still limited. This research aims to develop and validate diagnostic test questions to measure high school students' learning loss in the trigonometric function topic. This research uses preliminary research in the development stage with the Plomp model. The stages carried out in this study include self-evaluation and expert review. Document analysis is carried out at the self-evaluation stage by identifying basic competencies and formulating indicators, compiling a learning continuum, formulating attributes, compiling a Q matrix, and constructing questions. Then, three validators tested the validity and feasibility of the questions. The results of the validity test show that the 25 diagnostic questions that have been developed all meet the very valid criteria, with the average score for each item from the three validators being more than 3.20.
