As a method, a classical experimental design is used. The participants were from the department of English Language and Literature, and Translation and Interpretation. Students were randomly assigned to individual FL (the control group) class; and FL with cooperative activities (experimental group) class. The groups were randomly assigned as experimental and control by tossing a coin. The implementation took 10 weeks. Students’ performances (grades), social anxiety, and computer anxiety were dependent variables of the study and they were compared through multivariate analysis of variance. The results indicated that there is no significant mean difference between groups’ performances; however; the group of FL with cooperative activities had less social anxiety, but no significant change occurred at their computer anxiety level.
