Effect of Abacus Mental Arithmetic Training on Problem-Solving Ability of Students with Hearing Loss

The purpose of this study was to experiment if problem-solving ability of students with hearing loss is at variance by imparting the Abacus Mental Arithmetic Training. The research sample comprised of ninety 3^rd and 4^th grade students with hearing loss from special schools in Mumbai and its sub-urban districts in India. A quazi experimental pre-test/post-test non-equivalent control group design was employed. The problem-solving abilities were studied before and after the Abacus Mental Arithmetic Training using Porteus Maze Test. Results of the T-test – Assuming Equal Variances indicates that the problem-solving ability of the experimental group instructed via Abacus was superior as compared to the control group instructed using the conventional method.
