The document introduces the Pedagogical Patterns Collector (PPC), a tool for designing and sharing teaching patterns. It outlines activities for participants to: [1] browse, adopt, and adapt an existing teaching pattern using the PPC interface; [2] express a new design pattern using learning activity types; and [3] discuss how the PPC could be used to plan sessions for an online course. The goal is for participants to understand how the PPC can help teachers formalize, exchange, and improve their pedagogical designs.
