The Collaborative Learning training workshop was conducted as an e-learning session to explore the meaningful implementation of collaborative learning. Teachers engaged with videos, case studies, and assessment strategy discussions that examined both effective and ineffective group work. The session focused on task design, role clarity, accountability, and time management, with particular attention to assessment strategies that ensure collaboration genuinely supports learning rather than functioning as an unstructured group activity. As part of the module, a curated set of 16 practical strategies for implementing collaborative learning in large classrooms was shared to support scalability.
