Programa de intervención para la mejora de la ortografía en palabras regladas y arbitradas en escolares

Spelling is linked to the correct writing of words, with the understanding that a good command of spelling improves writing in general. The aim of this study is to design and evaluate the impact of an intervention program to improve spelling in Spanish-speaking schoolchildren. Based on a sample of 51 students from third to sixth grade of elementary school with poor performance in spelling, distributed into control and experimental groups, an intervention program was implemented with words selected from the study of frequency, orthographic particularity, syllabic composition, and length. The results indicate significant improvements in phonological and orthographic knowledge of the words that were worked on during the intervention by the experimental group, compared to the control group, at the end of the intervention and three months after it. It is again confirmed that spelling in Spanish is sensitive to systematic and programmed instruction based on the specific teaching of the orthographic rules, as well as to the repeated work on inconsistent words that help fixing the orthographic particularities, considering their semantic knowledge. The orthographic structure, according to the particularity of Spanish, has different levels of incidence according to the school grades.
