"Most successful FL learning takes place with no technology support at all."

'Optimal Psycholinguistic Environments for Distance Foreign Language Learning' (Doughty and Long, 2003) is a very good article ...if you are interested in task-based language teaching, or non-traditional FL teaching. It provides good description of methodological principles for TBLT. However, I thought that discussion of the distance learning was not the strongest point of this article. Perhaps, as the authors mentioned, it was because no such course had been developed yet, so their argument was not supported by strong evidence.
But what I thought was interesting is that they said that the most successful FL learning takes place with no technology support at all. However, it involves a lot of resources ...that many schools today do not have; it would involve smaller classes and therefore a larger number of classes, larger number of FL instructors, etc.
