It defines learning design as a methodology for helping teachers make more informed pedagogical decisions when designing learning activities and entire curriculums using appropriate technologies and resources. The document outlines several types of design representations including case studies, lesson plans, patterns, models, mind maps, and technical diagrams. These representations can be used at different levels of granularity from individual activities to full curriculums. The representations foreground different aspects of the design to support sharing and improving the design process.
