This document discusses ways to make error correction more constructive and fun for students. It notes that errors are a natural part of language learning and should be viewed as opportunities for feedback, not judged harshly. Various techniques are proposed to correct errors in a low-stress, game-like manner, such as using color coding, having students find errors in sample texts, or acting out incorrect sentences. Making the student being corrected "the expert" on their own common mistakes is recommended. The goal is to take the embarrassment out of errors and encourage experimentation in language use.
