Morphological Awareness in Reading Comprehension : A Secondary Analysis

Secondary analysis is beneficial to find further information and to get a meta-analytic thinking. Once means, standard deviations, sample sizes, and matrix summaries are provided, secondary researchers are able to conduct every correlational analysis in general lineal modeling. An exemplary secondary analysis was conducted in the present study to find practical significance of the effect sizes across studies on the role of morphological awareness (MA) in reading comprehension. Based on specific inclusion and exclusion categories, 10 studies were selected which generated 25 effect sizes in total. Secondary commonality analysis results showed that the MA effect on reading comprehension was unique from the vocabulary effect. However, the effect sizes for the unique MA effect were generally smaller than the common effects of MA and vocabulary. Importantly, the unique MA effect on reading comprehension was varied according to the learners’ grade level, L1 backgrounds, and types of morphological tasks included. Educational implications and future research recommendations were discussed.
