The Pedagogical Patterns Collector (PPC) is a web tool that allows teachers to browse, adopt, adapt, and share pedagogical patterns and learning designs. The PPC contains sample patterns that can be viewed generically or with examples for specific subjects. Teachers can use the PPC to design new patterns or adapt existing ones. Patterns can be saved, exported, printed, and shared with other PPC users. The tool is meant to facilitate collaboration and reuse of good teaching ideas across different subject areas.
