Computerized Cognitive Intervention: enhancement of arithmetic skills for solving algorithms and problems of a student with Developmental Dyscalculia

Abstract

This study is part of a research developed by the Study Group on Developmental Dyscalculia at the Pontifícia Universidade Católica do Rio Grande do Sul that addresses the contributions of a computerized cognitive intervention. It aims to analyze the enhancement of mathematical skills and the strategies used by a student with DD involved in solving algorithms and problems of addition and subtraction. This is a qualitative research, characterized as a prospective study with a single case experimental design. To carry out the psychopedagogical evaluation, the Arithmetic Subtest –version 1st to 5th year and a pilot test with problem solving were used. For the intervention process, the Calcularis® software was used. The analysis of the student's performance shows that the intervention contributed to reducing response time, increasing attention and calculation fluency, and significantly improving her performance in solving addition and subtraction problems.
