In this article, Megan Shenton, a final-year trainee teacher at Nottinghom Trent University, describes using "The Big Question" in her science teaching in a move away from objectives. The Big Question is an innovative pedagogical choice, where instead of implementing a learning objective, a question is posed at the start of the session to begin the learning journey. The Big Question allows the children to create their own success criteria; this informs what they do in the lessons and creates a more purposeful and effective set of personalised success criteria for individuals. This article shares the steps in planning the Big Question, the benefits of using the Big Question, what a typical lesson looks like in a science context, and implications for future practice.
