The result of the Thai single-head (clockwise) consonant writing practice series for children with intellectual disabilities

Abstract

Objectives To create and find the effectiveness of the Thai single-head (clockwise) consonant writing practice package for children with intellectual disabilities from aged 6 to 10 years.

Materials and Methods This quasi-experimental research was a one-group pre-test and post-test design by comparing Thai consonant writing skills before and after the intervention. Thirteen children with moderate intellectual disabilities from aged 6 to 10 years who received special education services were purposively selected as the sample group. The tools used in this study were: 1. Thai single-head (clockwise) consonant writing practice series, which included lesson plans, teaching materials, and consonant writing practices. The package was used to teach for 13 weeks; four classes per week, and 45 minutes per class   2. Thai single-head (clockwise) consonant writing skills test. Data analysis involved assessing Efficiency Validation using process efficiency (E1) and outcome efficiency (E2), with criteria of E1/E2 as 80/80. The Wilcoxon Matched Pairs Signed-ranks Test was used for statistical analysis.

Results The Thai single-head (clockwise) consonant writing practice package for children with moderate intellectual disabilities from aged 6 to 10 had Efficiency Validation of 83.06/81.54. The mean score of the children's Thai consonant writing skills after the experiment was significantly higher than before the experiment at the 0.05 significance level.

Conclusion The Thai single-head (clockwise) consonant writing practice package was effective enough to be implemented in the special educational classes for children with moderate intellectual disabilities since it reached the standard of Efficiency Validation and could help them build Thai consonant writing skills.
