Effects of Chunking on Reading Comprehension of EFL Learners: Silent vs. Oral Reading

This study investigates how EFL learners' chunking ability both in oral and silent reading affects reading comprehension, and how the chunking ability in silent reading relates to that of oral reading. The participants of this study consisted of 30 Korean university students taking a required 'English Reading' course. Chunking is a technique of grouping words into meaningful syntactic units for better understanding. Chunking was measured from pauses in oral reading. Results of this study suggest that the participants who can chunk properly both orally and silently display better comprehension of texts in general. However, chunking in silent reading was found to be a stronger indicator of improved reading comprehension. Also, the chunking skills in silent reading showed a statistically strong correlation with those observed in oral reading, suggesting that the chunking ability in silent reading may develop in parallel with that of oral reading. Oral as well as silent reading should be continuously practiced to improve reading comprehension of all levels of EFL learners, including low levels of learners. There is also a need to encourage students to read aloud with appropriate prosodic cues to help them read in meaningful units of words, therefore increasing EFL learners' comprehension not only in reading but also in listening.
