EVO Call for Participation and read all about EVO's programme for 2015 and the TESOL Annual Conference in Toronto in 2015.
This is a summary from Nina Liakos, the Lead coordinator:
For five weeks in January and February, TESOL experts and participants from around the world engage in collaborative online discussions or hands-on virtual workshops of professional and scholarly benefit. These sessions bring together participants for a longer period of time than is permitted by land-based professional development conventions and allow a fuller development of ideas than is otherwise possible.
Sessions are free and open to anyone around the globe. It is not necessary to attend the TESOL Convention in order to participate. All you need is access to the Internet. Choose a session from this year's offerings, listed below. And please inform your colleagues about this unparalleled professional development opportunity!
