In this final summary interview with Prof. Dr. Suzanne Narciss, we review all our learning about failure over the last few months. There is much we can do to encourage our students to learn from errors, including interactive formative assessment and feedback strategies, prompting reflection and adaptive strategies for dealing with errors and using other people's errors. As teachers we need to help students overcome their fear of failure by creating a positive error climate and supporting students to develop a more positive error mindset. But this is an area that is challenging to research and we still have much to learn.
