This document discusses developing high quality online and blended learning courses for professionals. It outlines the EU's School Education Gateway program which provides extensive online teacher professional development. Effective online teacher PD incorporates reflection, authentic tasks, and communities of practice. The Conversational Framework models the learning process through different types of interactions. The Learning Designer tool allows teachers to design blended learning activities based on this framework and share their designs. The Blended and Online Learning Design MOOC will use these approaches to collaboratively build knowledge around online course design.
