Keywords: Meta-analysis, morphological awareness, reading, writing, difficulties, vocabulary, training


The aim is to check, through a meta-analysis, the impact of morphological awareness training on writing, reading, comprehension and vocabulary of grade schooler. 31 studies were included in the meta-analysis; they were obtained from 19 articles that meet the selection criteria. Morphological awareness instruction has a high-medium and significant effect size in studied variables of literacy. On writing, g=0.491, SE=0.078, IQ=0339-0643, p=.000, reading, g=0.473, SE=0.096, IQ=0284-0662, p=.000, comprehension, g=0.468, SE=0.123, IQ=0227-0708, p= .000 and finally vocabulary, g=0.501, SE=0.152, IQ=0203-0798, p= .001. The test of Heterogeneity Q is only significant on writing so other moderating variables were explored but no differences between groups were found. It shows morphological awareness training improves reading, vocabulary and comprehension of grade schooler with and without reading difficulties. Nevertheless, the results on writing are more heterogeneous.
