Meta-discourse markers are an inevitable part of oral proficiency which improve both the quality and comprehension of learners’ speech. While studies of oral meta-discourse have been conducted since the 1980s in a European or US context, they have remained relatively untouched in Iran. Therefore, this study aimed to seek the impact of both explicit and implicit teaching of formal meta-discourse markers on EFL learners’ oral proficiency. To this end, the quantitative data were collected from ninety upper-intermediate students at Shiraz University Language Center. Two groups went through an instruction for an eight-session treatment. However the experimental group ‘B’ (N=45) were instructed the formal meta-discourse markers implicitly, the target formal meta-discourse markers were taught to the experimental group ‘A’ (N=45) explicitly. To compare the participants’ performances, an SOPI (Simulated Oral Proficiency Interview) posttest was administered. The results revealed that the instruction of meta-discourse markers had a positive effect on the learners’ oral outcome. Moreover, the findings showed that learners who received explicit method of teaching formal meta-discourse markers could perform better in speaking than learners who received implicit instruction. The findings can have pedagogical implications for EFL educators and materials developers to enhance learners’ oral proficiency. The findings also provide important insight into the effect of teaching discourse markers and raising learners’ awareness through explicit instruction to make pupils produce more cohesive and coherent speech.

This study, on the one hand, investigated whether or not strategies like Lexical Inferencing (LI) and Morphological Instruction (MI) can significantly affect English as a Foreign Language (EFL)learners’ reading comprehension, and on the other hand, it examined their effects on the learners’ vocabulary retention over time. For this purpose, 60 homogeneous EFLlearners were randomly assigned to two experimental and one control group each one consisting of 20 participants. After the pre-test, participants of the first experimental group received lexical inferencing strategy training for six 45-minute sessions. The second experimental group was also provided with morphological instruction for six 45-minute sessions and as for the control group, the participants followed their regular reading comprehension course without any specific strategy training. After the treatment, two post- tests with a short time interval were administered to the three groups and the obtained data were fed to different statistical tests to spot the probable differences among the three groups' first post- test performance as a measure of their learning differences and the second post-test performance as a measure of the learners’ vocabulary retention differences over time. Results of the paired t-tests for comparison of the within group differences showed that lexical inferencing instruction had statistically significant effect on EFL learners' reading comprehension development. On the other hand, it was found that morphological instruction had no statistically significant effect on EFL learners' reading comprehension development. The ANOVA analyses revealed that there was no statistically significant difference between the effects of lexical inferencing and morphological instruction on EFL learners' reading comprehension development. Furthermore, no significant difference was found between the effects of lexical inferencing and morphological instruction on EFL learners' reading comprehension development over time.
