This study allowed pairs of English language learners, a class in Turkey and a class in Spain, to have synchronous audio communication over the Internet. One component of the study had a quasi-experimental research design with two English oral communication classes in Turkey. The class who received CMC integrated instruction formed the experimental group and the class who followed regular English oral communication instruction constituted the control group. Oral proficiencies of the learners were measured at the beginning (pretest) and at the end of the study (posttest) through elicited 5-minute speech samples from each learner. Quantitative analysis indicated that the difference between the posttest scores of the experimental group and control group was not statistically significant at p <05.
