Investigating the effectiveness of scaffolded feedback on EFL Saudi students' writing accuracy: A longitudinal classroom-based study

Abstract

Despite the growing body of research on feedback provided to L2 learners on their writing, few studies have investigated the use of a scaffolded approach to feedback. Sociocultural scholars argue that for feedback to be effective it needs to be scaffolded – dynamic and aligned to the learner’s ability to correct their errors (Aljaafreh & Lantolf, 1994). Although research on scaffolded feedback have found it to improve L2 writing accuracy, most of this research has been small-scale, using one-on-one conferences. This larger classroom-based study aimed to examine the effectiveness of scaffolded written feedback and students’ perceptions of this feedback approach. The study was quasi-experimental and implemented over one academic semester. The participants were 71 male students of intermediate English proficiency, majoring in English at a large Saudi university. They were divided into two groups: one group received scaffolded feedback; the other group received unscaffolded (indirect) feedback. The feedback targeted eight grammatical structures. Findings from the immediate and delayed post-tests showed that both groups improved in their overall writing accuracy over time, with no difference evident between the two groups. Moreover, both groups showed similar improvements in six of the eight targeted grammatical structures. The scaffolded feedback group showed greater improvement than their counterparts only on two structures: subject-verb agreement and singular-plural agreement. Interview findings showed that the scaffolded feedback group liked this approach mainly because of its novelty but preferred scaffolding only when it increased in explicitness. We conclude by considering whether and how scaffolded feedback can be provided in classroom settings.
