The document discusses instructional planning activity types which can be used to develop teachers' TPACK (technological pedagogical content knowledge) in a standards-based way. It describes five steps in planning a learning event: choosing goals, pedagogical decisions, selecting and sequencing activity types, assessment strategies, and tools/resources. Each activity type captures what students do during learning, like group discussions or role plays. Using learning activity types helps create technology-enhanced plans for lessons, units and projects focused on standards and students rather than just tools.
