Abstract

Pedagogical Content Knowledge Technology (TPACK) is a framework that combines technology, teacher teaching skills, and knowledge. TPACK helps students learn numeration. However, the facts in the field show that students are still very short in numeration, especially the bullshit. This is demonstrated by the results of observations carried out in February 2023 at the Kandat State SLB, which showed that 77.8% of SD-LB 6th grade students have not yet been able to use the integer, and 85.7% of high school-level students have yet to use an integer multiplication. The results show that numeration needs special attention as it helps the student acquire the basic skills needed for life. This is the reason why the TPACK authorization should be given to the SLB teacher. This skill improvement can be achieved through the development of the Mathematical Sign Language (BIMA) learning product, which was developed using the ADDIE development model. The IHT results from the BIMA development show that students are better at counting.

Abstract

This study aimed to develop a website-based learning medium called Bang Rugee (Bangun Ruang GeoGebra Eksploratif Education), which integrates GeoGebra 3D simulations, a solid geometry calculator, and interactive quizzes to enhance Grade VIII junior high school students' understanding of three-dimensional geometry. The research employed a Research and Development (R&D) approach using the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation stages. The trial involved 34 eighth-grade students at SMP Negeri 1 Ngadiluwih using a one-group pretest-posttest design. Data were collected through expert validation sheets, student and teacher response questionnaires, and multiple-choice achievement tests. The validation results reached an average score of 87.1%, indicating that the medium was highly feasible. Practicality testing showed positive responses from students (93.1%) and teachers (90.6%), classifying the medium as very practical. Effectiveness testing revealed a significant improvement in students’ learning outcomes, with paired sample t-test results showing p < 0.05. The average N-Gain score was 0.42, categorized as moderate, accompanied by a large effect size and an increase in classical learning mastery from 32% to 76%. Furthermore, all students demonstrated improved posttest scores. The study concludes that Bang Rugee is a valid, practical, and effective learning medium for improving students’ understanding of solid geometry concepts and recommends extending similar technology-based media to other mathematics topics.
