How making mistakes improves learning

GCSE chemistry assessment objective 3 offers the opportunity for students to learn from their mistakes. Where it’s safe, let students make mistakes in their practicals and use the resulting problems and solutions in your teaching. This article describes how and suggests some common problems and their solutions.
