abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...

Second language writing instruction has been greatly influenced by the growing importance of technology and the recent shift of paradigm from a cognitive to a social orientation in second language acquisition (Lantolf & Thorne, 2006). Therefore, the applications of computer assisted language learning and activity theory have been suggested as a promising framework for writing studies. The prese...

The 1970s had been a period in which, in general, conventional theory had been challenged in the universities, at the sam...
