Abstract :
This study sought to investigate the probable effects of code-switching (CS) on Iranian bilingual English learners' reading comprehension. In this study, two intact classes of freshmen, taking the four-credit Reading and Comprehension Course 1, comprising a total of 70 participants, with 35 in each class, were randomly assigned as the experimental and the control groups after their initial homogeneity in reading comprehension was assessed via the reading section of the Preliminary English Test (PET). In the experimental group, the participants were allowed to switch codes during the twenty-hour-treatment that extended over five weeks. The participants in the control group, however, were required to rely exclusively on English as the language of communication and instruction with no CS. The independent samples t-test of the post test scores, administered at the end of the treatment, revealed significant differences in the reading comprehension of the two groups. The experimental CS group outperformed the control group. Since variables such as proficiency, teaching materials, and teach methodology, were kept constant in both classes, CS might be regarded as one of the probable causes of different levels of achievement in reading comprehension in both groups. Cautious use of CS to promote different aspects of the learning process will be discussed in the paper.
