Abstract

The present study investigated the effects of text modification (i.e. simplification and elaboration) on EFL learners’ incidental vocabulary acquisition. A sample of 150 university students majoring mechanics, chemistry, and metallurgy were selected to participate in this study. First, Nelson English Language Test was employed to select an almost homogenous group of participants. The mean score was computed, and 90 students who scored between one Standard Deviation (SD) above and one SD below the mean score were selected.  They were divided into three groups.  Four baseline passages were selected and two modified versions (simplified and elaborated) were derived out of each one (a total of 12 different texts). Each group read one type of text. Then in four sessions, after reading the texts, four vocabulary posttests were administered to the subjects of three groups to assess the extent of acquired incidental vocabulary. Then the means of three groups were compared through analysis of variance (ANOVA).  The results indicated that those students who read the elaborated texts had scored the least whereas the scores of the readers of the baseline texts and simplified texts were the highest with a slight superiority of the scores of the former group.
