The Effects of Reading Comprehensionon Three Dimensions of Vocabulary Learning

Abstract. The purpose of this study is to investigate the effects of reading comprehension on three dimensions of vocabulary knowledge, namely form recognition, meaning recognition and production among EFL learners. Furthermore, it investigates which dimension of vocabulary knowledge benefits most from reading comprehension. The participants were 40 Iranian male intermediate EFL learners at a language institute in Shiraz. They were asked to read the texts and answer a number of comprehension questions. Their vocabulary knowledge was examined immediately after reading the texts and two weeks later by three tests of form recognition, meaning recognition and production. One-way repeated measure ANOVA was employed to examine the differential effects of reading a text on different dimensions of vocabulary knowledge. The results indicated that reading comprehension has statistical effects on the acquisition of three dimensions of vocabulary knowledge in both short and long term retention. It also indicated that in short term retention, reading comprehension promoted the acquisition of meaning recognition knowledge more than the form recognition and production. However, with regard to long term retention, the findings revealed that reading comprehension promoted the acquisition of form recognition knowledge more than the other two dimensions of vocabulary knowledge.
