From Passive Worksheets to Dynamic Online Learning: Redesigning Network Tutorials via Design-Based Research and Cognitive Load Theory

<p dir="ltr">This presentation documents a curriculum redesign project in <i>COMP90007 Internet Technologies</i>, applying <b>Design-Based Research (DBR)</b> and <b>Cognitive Load Theory (CLT)</b> to transform traditional worksheet-based tutorials into engaging, interactive online learning experiences.<br>The redesign introduces a <b>four-phase model</b>—diagnose, construct, practice, and verify—supported by open educational tools such as <b>Kahoot, Claude AI, Padlet, and Miro</b>.<br>Findings show improved conceptual understanding, engagement, and transferability across multimodal delivery contexts. The presentation demonstrates how iterative design cycles and cognitive principles can enhance pedagogical effectiveness in postgraduate technical education.</p>
