Crosslinguistic Sharing of Morphological Awareness in Biliteracy Development: A Systematic Review and Meta‐Analysis of Correlation Coefficients.

This study examined the crosslinguistic sharing of morphological awareness (MA) in biliteracy development. The analysis included 34 correlational studies with 41 independent samples (N = 4,104). Correlational coefficients were meta‐analyzed, yielding four main findings: (a) the correlation between first language (L1) and second language (L2) MA was small (r =.30); (b) the interlingual correlations between L1 MA and L2 word decoding and between L1 MA and L2 reading comprehension were both small (r =.35,.39, respectively); (c) the intralingual correlations between L2 MA and L2 word decoding and between L2 MA and L2 reading comprehension were both moderate (r =.46,.52, respectively); and (d) MA measurement type and age were significant moderators. Our review suggests that there is a need for future research to align the definition and measurement of MA. [ABSTRACT FROM AUTHOR]
