There are many ways to assess learners, for example, mini-tests or observations, in order to evaluate and monitor their understanding and progress. As well as checking learners’ competencies in some specific language or skill, evaluation allows us to guide learners on how to improve. Part of this is noting any errors they make in completing the assessments, especially errors in the language they use. However, focusing on errors too much can be de-motivating for learners. They may struggle to improve because they are anxious about making mistakes, especially with productive tasks. So how can we correct English errors and at the same time keep learners motivated to improve?
