This document discusses the differences between accuracy and fluency in language learning. Accuracy refers to correct use of grammar, pronunciation, vocabulary and discourse. It focuses on error-free production. Fluency refers to ease, flow and comprehensibility of language. It focuses on expressing oneself without undue pauses or difficulties. Activities and materials for accuracy practice discrete items out of context, while fluency activities use authentic whole texts and simulate real-life communication, assessing information transfer over correctness. Both accuracy and fluency present issues when over-emphasized in language teaching.
