This document discusses the purpose and effectiveness of drills in language learning. It outlines the differences between meaningful communicative drills and mechanical drills that do not require attention to meaning. Mechanical drills are criticized for not engaging learners in comprehension or acquisition, as they do not provide input for learning. Meaningful communicative drills that give learners control over responses are preferable, as they foster acquisition through structured input and practice. The document questions whether drills alone can effectively fix new language structures in students' minds.
