A Computer-Based Method to Improve the Spelling of Children with Dyslexia

TL;DR

This study introduces a novel error-based spelling training method for children with dyslexia, implemented as a game on iPad, which significantly reduces spelling errors through targeted exercises based on linguistic error analysis.

Contribution

The paper presents a new error-based training approach for dyslexic children's spelling, integrated into a mobile game, demonstrating its effectiveness through a controlled experiment.

Findings

Children using DysEggxia made fewer spelling errors.

Error-based exercises improved spelling skills.

The method outperformed a control game in reducing errors.

Abstract

In this paper we present a method which aims to improve the spelling of children with dyslexia through playful and targeted exercises. In contrast to previous approaches, our method does not use correct words or positive examples to follow, but presents the child a misspelled word as an exercise to solve. We created these training exercises on the basis of the linguistic knowledge extracted from the errors found in texts written by children with dyslexia. To test the effectiveness of this method in Spanish, we integrated the exercises in a game for iPad, DysEggxia (Piruletras in Spanish), and carried out a within-subject experiment. During eight weeks, 48 children played either DysEggxia or Word Search, which is another word game. We conducted tests and questionnaires at the beginning of the study, after four weeks when the games were switched, and at the end of the study. The children who played DysEggxia for four weeks in a row had significantly less writing errors in the tests that after playing Word Search for the same time. This provides evidence that error-based exercises presented in a tablet help children with dyslexia improve their spelling skills.
