peer scaffolding

The present study aimed at investigating the effect of peer and teacher scaffolding through a process approach in a technology-enhanced environment on vocabulary learning among high and low self-regulated learners. Participants of the study were 120 English as a Foreign Language (EFL) learners who were selected based on their scores on a sample copy of the Oxford Placement Test (OPT). The participants were divided into three groups each consisting of 40 learners. One group of the participants received peer scaffolding; the second group was exposed to teacher scaffolding via the Telegram app based on process approach principles, while the third group served as the control group. The control group received conventional vocabulary teaching in such a way that the Telegram app was not employed. The learners in the control group were also provided with vocabulary exercises in the vocabulary book (English Vocabulary in Use). Data were collected through a sample copy of OPT, a vocabulary test, and a self-regulation questionnaire. The results of a one-way ANOVA revealed that both peer and teacher scaffolding significantly affected vocabulary learning. However, there was no significant difference between peer and teacher scaffolding in terms of their effects on vocabulary learning. The results of a two-way ANOVA indicated that the main effect of treatment on vocabulary learning was significant; however, there was no statistically significant difference between the effects of the two treatment modalities on students’ vocabulary learning.

This study investigated a new blended approach for enhancing vocabulary achievement. To this end, the project used a convenience sample of 50 intermediate EFL learners ranging from 19-35 years of age from three intact classes studying English translation at university. They were randomly assigned to two groups of 25 students each. In the experimental group, the treatment consisted of providing photos/cartoons related to the sessions’ course of instruction on Instagram, with the learners discussing and exploring the meaning of vocabularies via peer scaffolding using metacognitive strategies. The control group followed the syllabus and assigned homework according to the class program. To investigate the vocabulary achievement of the participants, a piloted multiple-choice vocabulary posttest was administered. The results that were analyzed through independent samples T-test revealed that the blended approach could significantly affect the performance of the experimental group. This study has implications not only for teachers, researchers, and syllabus designers but also for EFL learners with unpacking the notion of metacognition and peer scaffolding, proposing an integrated framework that illustrates how it may pervade the teaching-learning process as an educational goal. The implication of this study supports student responsibility, a student-centered classroom, and higher levels of cognition.
