While telecommunications and telematics have been available in schools and universities for decades, the speed of adoption of the Internet into general use has been unprecedented. This has placed a great deal of pressure on university teachers to re-evaluate their roles in the light of new teaching and learning opportunities. The Internet has opened up possibilities beyond the simple acquisition of information, and has created teaching and learning challenges that many teachers feel ill-equipped to meet. This chapter examines the impact of the Internet on the teacher’s role and explores the types of skills and strategies that teachers will need to be effective and efficient in online learning environments. The professional development needs for the new role of online teacher will be discussed within the context of a Graduate Certificate in Online Teaching and Learning designed to encapsulate authentic approaches to learning.
