Summary
Decoding training improved reading speed for children struggling with hiragana. While reading errors initially showed no significant change, further analysis indicated improvement after additional training.
Area of Science:
- Developmental Psychology
- Educational Psychology
- Linguistics
Background:
- Hiragana reading difficulties impact early literacy development in Japanese children.
- Targeted interventions are crucial for addressing symbol-sound correspondence deficits.
Purpose of the Study:
- To evaluate the effectiveness of computer-based decoding training for children with hiragana reading difficulties.
- To assess improvements in reading speed and accuracy.
Main Methods:
- A 3-week, 5-minute daily computer-based decoding intervention was administered to 15 first-graders.
- A control group of 20 children received no intervention.
- Reading aloud tests measured reading time and errors before and after the intervention.
Main Results:
- The intervention group demonstrated a significant reduction in reading time compared to the control group.
- No significant difference in the number of reading errors was found between groups initially.
- An extended study with control group participants showed improvement in reading errors but not reading time.
Conclusions:
- Decoding training effectively enhances reading speed in children with hiragana reading challenges.
- The training shows potential for reducing reading errors, particularly with extended application.
