In-class feedback is an invaluable component of the teaching and learning process. It is an important tool by which students understand how well they are doing and what they need to do differently before completing their final assessments and receiving their summative marks. It also enables teachers to assess how well their students are following along and comprehending the material, after which they can adjust their teaching and lesson planning as necessary. However, giving effective feedback in-class can be difficult. In-class feedback is often given publicly, in front of a whole class of students, which means it risks embarrassing a student when delivered poorly. While there are always exceptions to these usual characteristics, the on-the-spot and public nature of in-class feedback can make it difficult to deliver effectively and confidently. The purpose of this short guide is to highlight the most important considerations for giving and receiving effective in-class feedback.
