Objectives: This study aimed to examine the effects of an intervention using the gamification-based morphological approach on the abilities of writing letter-sound non correspondences in children with poor writing skills. Methods: In this study, a multi-probe design was used to verify the effect of intervention. The subjects were three children with poor writing skills (grade 2–3). Their writing skills were examined through tests of treated and untreated graphemes (eojeols) in the baseline, intervention, and maintenance phases. In this study, we applied the morphological approach that helps students to write the letter-sound non-correspondences through a game. Additionally, we provided instruction that helps them to learn the morphological knowledge and phonological rules. Each student was trained twice a week for 10–14 sessions. Results: All students were found to have high improvements in the letter-sound non correspondences eojeols. In the generalization phrase, all students showed improvements. In the maintenance phase, all students were found to have a similar effect size. Conclusion: First, gamification-based morphological approach on writing skills promote awareness of morphological knowledge in children with poor writing, and have a positive effect on letter-sound non correspondences eojeols. Additionally, training in applying morphological knowledge promotes children’s writing skills that remain in the early stages of writing development. Second, gamification-based intervention can elicit interest and motivation in children with poor writing and can be repeatedly trained.
- Morpheme knowledge
