Bett is a gigantic trade show, with over 30,000 people coming to East London’s ExCel Centre every year, and 600 resource and solution providers exhibiting in its massive halls. Amongst the new products, innovations, conversations and meetings, however, is the public, with that overriding question: what can I find here? This week, we invite a teacher, educational technology researcher, and founder and CEO, to answer why they return to the show year after year, and what questions they ask of the technology on display, and the predictions made in the heart of the Bett arenas.
