This document summarizes research on helping language learners attend to grammatical form in the input. It discusses theories that learners' attention is oriented towards meaning, not form. The document then presents research showing that activities requiring learners to practice form-meaning connections can help orient their attention to grammatical forms. However, it notes limitations, such as whether this approach helps with rules lacking clear L1-L2 mappings or abstract syntax. The document concludes that practicing form-meaning connections through controlled activities can promote grammatical knowledge.
