"the European Association for Computer Assisted Language Learning. EUROCALL aims to provide a European focus for the promulgation of innovative research, development and practice relating to the use of technologies for language learning."
I don't think I can annotate this article because it is a Google book and has access limitations. I have worked with Dr. Christine Appel, one of the authors of the article "Synchronous tandem language learning in a MOOC context: A study on task design and learner performance".
My main interest here is: "How can we best design online synchronous tasks to achieve the optimal outcome?". Sometimes we focus too much on the tool and not so much on how we can make the most of it. The article studies real tasks to find the effects task design have in student performance.
