No Hands Up is actually a simplification. Generally speaking, it is about a changed classroom dynamic in which the teacher poses questions to the whole class rather than to individuals. One a question is set, children have time to think through their answers and/or discuss their ideas with a partner. Once that thinking time is over, every single child has no excuse for having nothing to share. The teacher can select any child, and everybody can – at least – rehash what they discussed with their partner. A good teacher can then weave their ideas into a learning narrative.
Finally, crucially, No Hands Up refers only to children’s answering, children raise their hands whenever they like to ask questions.
