The participants in the control group were exposed to the same listening tasks during 15 sessions. They did not receive any strategy training, discussion, or awareness-raising about tive listening strategies before, during, and after listening to the materials. But the difficult vocabulary or ideas were presented to them as a pre-listening activity. After the treatment stage was completed, the parallel form of the pretest was administered to the participants in both groups as the posttest. This test was the parallel form of the pretest used in the experiment, consisting of 20 items. The objective of items included in the posttest was to test the selected listening sub-skills. The total number of listening sub-skills selected to be tested in the listening posttest was 15. As a matter of fact, the purpose of the posttest was both to measure the listening comprehension proficiency of the experimental and control groups after the treatment and to test. the sub- skills of listening ability.
