To explore the effects of writing intervention on students with learning disabilities, the author reviewed 13 researches (N=40) on writing instruction via single subject design by conducting meta-analysis. For composition quality, the average PND at posttest was 92.17% and the average PND at maintain posttest was 89.14%. For length, the average PND at posttest was 74.58%, and the average PND at maintain posttest was 74.58%. Besides, there were no statistically significant differences between dependent variables on education level and intervention type variables, as revealed by the Kruskal-Wallis procedure. |
