Information and Communication Technologies (ICT) can connect with language teaching to make language learning more open, more enjoyable, and – some claim – more effective. Yet language teachers interested in integrating ICT (more) into their teaching activities face many challenges, which could be met with the help of adequate and flexible professional development. Drawing on recent research carried out by the AILA Research Network TPLang21 and by the speaker, this talk will provide an insightful picture of global language teachers‘ professional development activities. The final part of this talk addresses the ways in which the ICT-REV project at the European Centre of Modern Languages has sought to support language teachers in their individual and networked ICT-related professional development.
