The main materials applied for the experimental group were cards containing roles to be practiced in the class on the basis of TBLT considerations. The participants in the control group did not experience working with TBLT- based role play cards. As mentioned so far, to measure the subjects' speaking ability, the study has utilized IELTS speaking in its pretest and posttest. As stated earlier, role-play cards were provided and assigned to the subjects in the experimental group. They were developed according to TBLT conditions and those in the experimental group were asked to play the roles described on each card. The subjects in the control group followed the materials provided for them based on traditional methods of language teaching without encountering TBLT-adopted role-play cards. Following the implementation of IELTS speaking in pre test stage, the recorded samples of the subjects' performance were assessed by four raters and two raters with the closest means of scores were selected for both pre and post test assessment. As Table 1 reveals, the experimental and control groups had rather similar means, standard deviations and variances which prove the fairness of the selection and sampling process. As Table 2 reveals the result of t-test for both groups in the pretest. It seems that experimental group outperformed the control group. To see if the difference between the means of the experimental group and the control group was meaningful, another independent t.
