This collection sets out one project design that any teacher, in any subject, can run: students choose a topic, research it as deeply as they can, organise what they find into a book of their own design, then build videos, slides or a website from it and publish the work so that other people learn from it. It draws together the research on learning by teaching, on project-based learning and on open pedagogy, and is candid about what that evidence does and does not show. It treats the finished book as the research base for the original project that follows, whether a scientific study, an invention, a business plan, a campaign or an environmental or economic solution. The later modules cover the team as a publishing house, distribution and impact, and the scoping, timeline, assessment and AI policy that make a tangible result certain for every team.
