This document discusses providing written feedback and error correction to language learners in the classroom. It notes that error correction is a part of the learning process, not the end goal. It recommends using a "no code" approach where teachers do not explicitly identify and correct every error, but rather provide feedback to guide student learning. The document also suggests collaborative error correction activities where students work in groups to identify and correct sample errors, and encourages allowing some use of students' first language during these activities. It addresses common concerns that collaborative activities take too much time and that students cannot think critically enough, reassuring that the benefits are worth it.
