Design patterns can help support others in making successful design decisions for online teaching by drawing inspiration from previous successful designs and making that knowledge reusable. The document discusses how design patterns make tacit design knowledge visible, shareable, and reusable. It provides an example environmental familiarization activity pattern and discusses how design pattern workshops that incorporate narrative cases, design challenges, and prototypes can help facilitate the capture and reuse of expert design knowledge at scale. In summary, design patterns can transfer representations of practice that are appropriate for the user, present essential elements, encourage creative use, and add the voice of expert designers.
