A second objective is to investigate how the use of synchronous computer mediated written practice motivates and enhances the students' learning of the language. The participants ( N =56) were 9 th and 10 th grade English-speaking students enrolled in a beginning Spanish class. A paired sample t test was conducted to evaluate whether SCM written exchanges or face-to-face written practice influence language production. The results indicated that the mean language production for CMC written exchanges ( M = 1.79, SD = .833) was significantly greater than the mean language production for face-to-face written exchanges ( M = 1.11, SD = .737, p = .002). Qualitative results suggests that engaging learners in authentic interaction with other students of slightly higher language proficiency through the use of textual synchronous technology enhances their language skills as well as their overall learning experience.en-USComputer-mediated communicationSecond language proficiencyBilingual educationEducational tests and measurementsCurriculum developmentThesis
