Contribution of Morphological Awareness to Second-Language Reading Comprehension

This study investigates the contribution of second-language (L2) morphological awareness to foreign language reading comprehension. Tenth graders (n = 188) at a South Korean high school were assessed on 6 reading- and language-related variables: phonological decoding, listening comprehension, vocabulary knowledge, passage-level reading comprehension, metacognitive reading awareness, and morphological awareness. A series of 10 sequential regression analyses were conducted to determine the unique reading variance accounted for by each of the 2 morphological awareness tests included in this study (i.e., the Test of Morphological Structure–Revised [TMS–R], the Verbal Suffix Knowledge Test–Revised [VSKT–R]). The result revealed that morphological awareness was a significant predictor of L2 reading comprehension when other variables were controlled. Of the 2 tests, the TMS–R—a measure that primarily tested derivational morphological knowledge—showed stronger predictability. This provides evidence that morphological awareness, especially derivational morphological knowledge, is an important variable to be considered in explaining L2 reading comprehension among older readers.
