For over a decade, the TESOL (Teachers of English to Speakers of Other Languages, Inc.) Computer-Assisted Language Learning Interest Section (CALL-IS) has been providing free professional development annually for members and nonmembers alike. In this poster session, the past co-coordinator of the 2012 Electronic Village Online (EVO) will address the collaborative processes that occur in a large-scale, multi-national, open-source project. These include training and mentoring trainers, selecting free technology tools to provide online learning platforms, investigation of Web 2.0 technologies for application to the classroom, and the wholly volunteer nature of this project.
