The present research investigated the effect of self-regulatory approach (with two components of self-checking and self-efficacy) on pre-intermediate Iranian learners' lexical segmentation in listening comprehension via authentic listening comprehension texts. To achieve this purpose, the investigators administered an Oxford Placement Test (2007) to ninety-eight students of two girls’ private junior high schools in Abadan. The participants were in grade seven at pre-intermediate level. Ninety-two students were selected out of ninety-eight and after homogenizing the participants linguistically, they were divided into four groups. Twenty-three students of every 4 classes whose scores were nearly the same were considered as one group. There were one control group and three experimental groups. A teacher-made pretest which was piloted by the researchers was administered to all groups. Then, the experimental groups were instructed under an eight-sessions treatment which was self-regulated teaching via authentic and non-authentic texts. Finally, the participants took a posttest similar to the pretest on lexical segmentation in listening comprehension. Both pretest and posttest reliability were calculated with Cronbach Alpha. Statistical analyses were done through one-way ANOVA. the result of the study indicated that self-regulated approach teaching through authentic materials can improve learners’ lexical segmentation of listening comprehension.

This study investigated the effects of corrective feedback (CF) on the acquisition of English prepositions to find out which one would be more effective for third-grade high school learners in their grammar performance. This study also examined declarative and interrogative recasts to see which one the participants preferred to improve their grammar performance. To this end,75 out of 130 female students at the intermediate level in Khorramshar took part in this study. The participants were randomly assigned into one control and two experimental groups. All three groups took the same pre and posttests; however, the treatment was different. The recast group received CF in the form of recast and the other in the form of metalinguistic clues. The control group only received general comments, like good, bad, etc. The results indicated that both experimental groups improved in preposition recognition and production in their grammar performances. The findings also showed that there was no significant difference between the students'' performance in experimental groups, but metalinguistic CF was more helpful. A careful calculation using a questionnaire based on 5-points Likert Scale showed that there was no significant difference between the participants'' preference for two types of recast by the group receiving recasts.
