The document discusses instructional planning activity types that can help teachers develop curriculum-based technological pedagogical content knowledge (TPACK). It describes five steps of the planning process: choosing learning goals, making pedagogical decisions, selecting and sequencing activity types, selecting assessments, and choosing tools. Learning activity types represent what students do during learning and can be combined into lesson plans, units or projects. The document advocates for standards-based, student-centered planning rather than a technocentric approach that focuses on technologies over student learning needs.
