Abstract

This study investigated the effect of collaborative learning (CL) and scaffolding strategies through the Learning Management System (LMS) on EFL students’ writing performance. Employing an explanatory sequential mixed-methods design, 180 upper-intermediate EFL learners (90 undergraduates and 90 postgraduates) from four universities in Isfahan were selected via convenience sampling. The quantitative phase used a pretest-posttest non-equivalent control group design. One experimental group received CL-based instruction via LMS, the other applied scaffolding strategies through LMS, while the control group used traditional methods. All groups attended 14 weekly 90-minute sessions. Quantitative results (one-way ANCOVA) indicated that both CL (p = .000, p < .05) and scaffolding (p = .01, p < .05) significantly improved writing skills, with CL being more effective than scaffolding (p = .02, p < .05). The qualitative phase, using thematic analysis of semi-structured interviews, revealed five key themes: digital and technological literacy, instructional quality, infrastructure, assessment, and satisfaction.
