The document discusses using social media for continuing professional development (CPD) among teachers. It notes that Twitter allows teachers to connect with thousands of other teachers to share ideas and experiences. Using hashtags can help teachers follow topics of interest.

While school administrators initially saw social media as problematic, it can also be used as a positive learning tool to engage students, provide praise and information, share links and videos, and discuss real-life events.
