Minus Master: 3d MMOG Game-Based Learning for Improving Dyscalculia Subtraction Skills

Abstract

Having strong math abilities is a necessary skill for a child to succeed and do well in school. It will present a challenge to students who struggle to process numbers and solve mathematical problems, such as children with dyscalculia. In order to solve this issue, this study offers Subtraction Quest, a 3D platformer game made especially to help children in the 8 to 9-year-old age range develop their subtraction abilities. The game offers a dynamic and entertaining learning experience by fusing entertaining gameplay with instructive materials. Subtraction Quest has two unique stages. The first stage will test players' comprehension of subtraction symbols, and the second will test them by having them answer word problems and basic arithmetic issues. Developed with Unity, the game makes use of educational psychology concepts to improve motivation and learning memory. The effectiveness of the game in enhancing students' subtraction abilities was evaluated through testing. System Usability Scale (SUS), along with pre- and post-tests, was employed to assess user satisfaction with the developed game and evaluate students’ performance following gameplay. The results indicate an increase in children's confidence and a strong desire to repeatedly engage with the game. Subtraction Quest can be a valuable tool for educators and parents who are trying to help their children who are having difficulty with this basic mathematical operation by making subtraction practice enjoyable and engaging. Future enhancements may include making the information more age-appropriate and extending the game's coverage of other arithmetic operations.
