摘要：One of the techniques affecting incidental learning is using textual enhancement. This study was conducted in order to see whether textual enhancement positively affects incidental learning of idiomatic expressions. To do so, a quasi-experimental study with pretest-posttest control group design was carried out. The participants were 40 Iranian intermediate learners selected via convenient sampling and were randomly assigned to control and experimental groups, 20 participants in each. Before the treatment, Idiom Knowledge Scale (IKS) test, taken from Wesche and Paribakht's (1996) was administered to both groups, as pretest. Then the experimental group was exposed to idioms presented with four different textual enhancement techniques (color-coded, bolded, Italic and sticky papers). After the treatment, IKS, was again administered to the groups, as posttest. The results of data analysis through ANCOVA indicated that the experimental group outperformed the control group and that the implementation of textual techniques could enhance the incidental idiom learning.
