Abstract Studies over thirty years show that many deaf and hard of hearing students are under performers in the field of mathematics as compared to their hearing counterparts. This study explored the contribution of system dynamics methods to improving understanding and performance of deaf and hard of hearing students in økonomi'-commercial mathematics. The contribution of system dynamics method was assessed through an interactive learning environment (ILE) component Math Interactive Learning Environment for Students (MILES). The MILES, a computer-based simulator for solving mathematical problem was developed and used to carry out the system dynamics instruction. The experiment involved first term tenth-grade DHH students as the main participants. They were given the task of solving mathematical problems using the developed MILES after the teaching experiment. The result indicated an improved performance of the deaf and hard of hearing in solving mathematics problems. Participants pointed out that the use of icons, graphs and the simulation process in the MILES facilitated their understanding of the topic. In conclusion, although the results may not be generalised due to the sample size, the result is conclusive in the context of this study. Key words: Deaf and hard of hearing, mathematics, system dynamics method, interactive learning environment, teaching.
