Vocabulary breadth

Fluent reading is a multifaceted ability that integrates several linguistic and non-linguistic processes. Accordingly, recognizing the critical components of fluent reading is highly significant in planning and implementing effective reading programs. This study was undertaken to evaluate the predictive power of syntactic knowledge, vocabulary breadth, and metacognitive awareness of reading strategies in the reading fluency of Iranian EFL learners. To this end, a sample of 149 Iranian EFL language learners took the Vocabulary Levels Test, Survey of Reading Strategies Questionnaire (SORS), a TOEFL PBT, and a fluency test. The linear regression results indicated that vocabulary breadth was the first predictor of readers' performance on reading fluency, followed by metacognitive awareness of reading strategies. At the same time, syntactic knowledge was not entered into the regression model. Moreover, the findings confirmed the contribution of both linguistic and non-linguistic processes to reading fluency. Having a clear picture of fluency components can be advantageous to teaching reading comprehension and test score predictability.

Two main features of vocabulary knowledge, namely breadth and depth, have a fundamental role in vocabulary research. This research aimed to study the relationship between vocabulary knowledge and reading comprehension, and to investigate which feature of vocabulary knowledge, breadth or depth, had better impact on identifying reading comprehension performance. Therefore, three language tests were used, including a reading comprehension test, Vocabulary Levels Test, and Word Associates Test. 64 students majoring in Medicine at Ferdowsi University of Mashhad, Iran, participated in the study. The outcomes of the two-tailed Pearson Correlations and multiple regression analyses declared that test results on vocabulary breadth, depth of vocabulary knowledge, and reading comprehension were positively correlated and breadth and depth of vocabulary knowledge were closely interrelated.
