Comparing the Efficiency of Task-based Interactive Language Teaching and Task-based Language Teaching on Language Learners’ Fear of Negative Evaluation in University Heterogeneous Classes

Psychological barriers have always had negative effects on English learning. This research was done to compare the efficiency of TBILT and TBLT on learners’ fear of negative evaluation. The statistical population included all 4200 Babol Azad University students of whom 320 were volunteers to participate in English language classes via public invitation. Then, 90 students were selected using available sampling model and were placed randomly in three groups (two experimental and one control). Before starting teaching, Leary’s fear of negative evaluation questionnaire with Cronbach’s alpha of .769 was administered, and then using three methods namely TBILT in the first experimental class, TBLT in the second one, and Traditional method (GTM) in control group, the teacher taught in 20 sessions, 90 minutes each. After the post test, the two-way single variable co-variance and the Post Hoc Tukey Test revealed that both experimental groups did much better than the control group (p <.001). On the other hand, the TBILT group acted much stronger than the TBLT one (p <.001).
