The Effect of Textual Enhancement Types on EFL Learners’ Grammatical Awareness of Simple and Complex Structures

The purpose of this study was to investigate the effect of textual enhancement types on English as Foreign Language (EFL) learners’ grammatical awareness of simple and complex structures. A num-ber of 104 learners from Ayandegan Institute, in Tehran, participated in this study. To homogenize the samples, the researchers administered a placement Michigan Test of English language to the par-ticipants. The participants were then divided into four groups, two experimental groups and two con-trol groups. The two experimental groups went through enhanced forms of the texts containing sim-ple and complex structures, while the two control groups experienced unenhanced forms of the texts containing simple and complex structures. Before and after the treatment, a pretest and a posttest were run and the two reading texts with enhanced and unenhanced versions were used. The findings showed that the textual enhancement had significant effect on learners’ grammatical awareness of simple and complex structures. There was also a significant difference between male and females’ scores in simple and complex structures.
