Abstract
Socioculturally oriented developmental Interlanguage Pragmatics (ILP) studies have just recently drawn the Second Language Acquisition (SLA) researchers' attention, and the role of concepts like peer scaffolding, and the Zone of Proximal Development (ZPD) in ILP development are among rich areas in need of attention. The present study investigates the significance of the effect of expert peers' ZPD-wise, co-equal peers' ZPD-insensitive and teacher fronted ZPD-insensitive scaffolding on EFL learners' pragmatic development. The number of students who participated in this study was 85 of which 27 were male and the rest were female. They were organized into three experimental and one control groups. The subjects in the experimental groups were given either explicit ZPD-wise or implicit ZPD-
wise scaffolding by the expert peers, or ZPD-insensitive scaffolding by their co-equals, while the subjects of the control group received ZPD-insensitive teacher scaffolding. The study reveals that the expert peers' ZPD-wise explicit and implicit scaffolding are more effective than the other two intervention types for the ILP development, however, the co-equals' scaffolding proved to be the third effective procedure for the subjects' co-construction of ZPD and ILP development. An implication of the study is that different forms of peer scaffolding are relatively effective for the EFL learners' ILP development.

Abstract
| In this research, we carried out a meta-analysis of the effects of teacher scaffolding on EFL learners’ reading proficiency in which 28 experimental and quasi-experimental studies published from 2008 to 2022 and 39 effect sizes were reviewed and synthesized. Three questions guide this analysis: What is the overall effect of teacher scaffolding on EFL learners’ reading proficiency? To what extent moderator variables such as learners’ educational levels and proficiency levels modify the effect of the teacher scaffolding? What is the magnitude of publication bias in this analysis? The overall effect size was found to be 0.89, which represents a large effect size based on Cohen, Manion and Morrison’ (2007) scale. The effect sizes of moderator variables were calculated and it was reported that the scaffolding has the most effect in elementary learners and elementary school level. The symmetrical funnel plot together with the fail-safe N test indicates that publication bias does not have any significant effect on the effect size reported in this study. The findings of this meta-analysis have implications for EFL teachers, researchers, policy makers and curriculum developers. |
