CLT with Grammar Instruction. People learned languages before institutionalized education existed. Natural learning processes always assert themselves over outside intervention (grammar instruction). Traditional approaches to grammar instruction are not effective in promoting acquisition.
Does explicit instruction in grammar, together with practice, error correction, etc., have any significant effect on how learners acquire a language?
“Using an approach in the classroom which emphasizes the ability to exchange messages, and at the same time testing only the ability to apply grammar rules correctly, is an invitation to disaster.” (Krashen)
