This document discusses open educational practices in language teaching, with a focus on telecollaboration. It provides an overview of beliefs about language teaching and learning, including ideas from Lightbown & Spada. Telecollaboration activities should focus on meaning over form, include information gaps, not pre-teach all language, and result in authentic use. Synchronous and asynchronous exchanges can be written or oral. Examples of projects integrating telecollaboration in secondary language learning are provided. Copyright considerations for open resources are also addressed.
