Radial blended-collaboration in doctoral education: Insights from an Indonesian higher education institute

Abstract

This study explored how doctoral educators apply a radial blended collaborative (RBC) strategy to teach EFL speaking. This study used a narrative case study design and a qualitative approach. In doing so, teachers employed eight RBCs' strategies: raising collaboration awareness, forming groups based on 21st-century skills, using controlled-chosen topics and theme-based prior knowledge, employing snowball questioning techniques, engaging in role-play in different contexts, conducting peer evaluations, and providing oral and written feedback. This study found that technology integration, such as WhatsApp, Zoom Meeting, Google Classroom, and electronic mail, enhanced the learning experience, whereas pooling WhatsApp messages was used to direct the chosen discussion topics. The results demonstrated that RBC significantly improved students' speaking performance across four instructional dimensions: collaborative awareness, active learning, classroom interaction, and technological integration. Future research should aim to enhance spoken communication by integrating technology in assessments and fostering collaborative learning environments.
