Evaluating the impact of new teaching approaches - design and technology

These videos guide you through the process of evaluating the impact of changes you make to teaching approaches in your classroom. The evaluation approaches described here will enable you to tell whether new approaches are more effective than what they have replaced. You'll be able to make evidence-informed decisions based on data collected through planned evaluation. 

These videos have been created by STEM Learning in collaboration with the Institute for Effective Education. The IEE works to improve education by promoting the use of evidence in education policy and practice. The videos are led by Alicia Shaw, Innovation and Evaluation Lead at the IEE.
