Fostering Learner Autonomy in EFL Classroom: The Impact of New Learning Guidelines and Relational Pedagogy
Get PDFLearner autonomy is a critical outcome in EFL education, yet the mechanisms through which instructional frameworks and educator behavior influence autonomous learning remain underexplored. This study investigates the impact of the New Learning Guidelines, a structured pedagogical framework, on the development of learner autonomy among undergraduate EFL students. Employing an explanatory sequential mixed-methods design, the study involved 539 students categorized into positive (n = 78) and negative (n = 462) attitudinal groups. The quantitative data were collected through structured questionnaires, and qualitative data were collected via semi-structured interviews. Quantitative findings revealed that students with positive attitudes demonstrated substantial gains in goal setting, strategic planning, and self-monitoring, whereas those with negative attitudes showed limited improvement from structure alone. Thematic analysis underscored the role of relational scaffolding, emotionally responsive, supportive teacher-student interactions as a critical factor in fostering autonomy among disengaged learners. These findings challenge deficit-based perspective on learner motivation and advance autonomy theory by emphasizing its socio-relational dimension. The study suggests EFL educators may integrate clear instructional guidelines with affective and relational pedagogies to address diverse learner dispositions. Practically, the findings underscore the need for teacher training programs to integrate relational strategies with structural management to promote learner autonomy effectively

Harnessing Students’ Creativity and Participatory Learning: A Step-by-Step Guide to Conducting Project-Based Digital Photovoice in ELT
Get PDFThis "how-to" article presents a step-by-step guide to implementing a project-based digital photovoice in the context of English Language Teaching (ELT). While photovoice has been widely used as a pedagogical strategy in ELT, there is limited research on digital photovoice (DP) that integrates documentary photography, interviews, and web-based graphic design tools. Building on a series of DP initiatives, this article explores how DP-based instructions facilitate students' autonomous, authentic, flexible, collaborative, and participatory learning activities beyond the classroom. The process begins with engaging students in photo-taking activities, where they capture objects in their surroundings based on the project's theme. Subsequently, they conduct interviews with relevant informants to gather information about the objects. The students then analyze the images and interview data as primary sources to create the DP. Finally, they utilize Canva, a web-based graphic design tool, to produce the DP and share it digitally through social media applications. This approach has implications for integrating the DP project into Computer-Assisted Language Learning (CALL) innovation and pedagogy
