This study investigated whether Lexical Inferencing (L1) and Morphological Instruction (MI) can significantly affect EFL learners’ reading comprehension, furthermore, it also examined their effects on the learners’ vocabulary retention over time. 60 homogeneous EFLlearnerswere randomly assigned to two experimental and a control groups. After the pre-test, participants of the first experimental ...

This study synthesizes 79 standardized mean-change differences between control and treatment groups from 17 independent studies, investigating the effect of morphological interventions on literacy outcomes for students with literacy difficulties. Average total sample size ranged from 15 to 261 from a wide range of grade levels. Overall, morphological instruction showed a significant improvement...

There are a number of reasons why knowledge of morphology should be related to literacy outcomes: (a) English is fundamentally morphophonemic in nature, (b) various theories give morphology a role in word reading, (c) there is evidence that adults process morphological information automatically when they read words, even if they are not aware of it, and (d) there is considerable evidence that k...

Children who have difficulty with literacy development often experience pervasive and enduring trouble with spelling, even after receiving remedial instruction. Our study tests a new approach to improving the spelling of these children. We designed an instructional program emphasizing the morphological structure of words, and directly contrast its benefits to instruction that focuses on word me...

The effects of a 20-session intervention targeting morphological word structure on vocabulary knowledge were investigated in four Grade 4 and 5 classes, assigned randomly to treatment and control conditions. Hierarchical regression analyses controlling for initial vocabulary showed significant instructional effects on morphological analysis and vocabulary with words that were taught directly an...

We compared the effectiveness of two spelling interventions: one focused on morphological structure and one emphasizing word meanings,, on spelling acquisition in French speaking children in 3 and 5 grades. The morphology intervention led to significantly greater improvement in spelling than the vocabulary intervention, especially for children in grade 5. To compare the long-term effects of the...

This article presents results from a recent study that isolated grammar instruction that is deductive (i.e., involving rule presentation and metalinguistic information) as a variable and contrasted it with an instructional treatment that is inductive (i.e., focusing on form with no explicit grammar instruction). The effectiveness of these two types of instruction was compared on measures of bot...
