The author analyzes the failure of the project to establish a TBI (interactive whiteboard) in all schools in Quebec and it reveals the causes. It then looks at the chances of success of the massive introduction of digital tablet. He concludes that, pushed by orders of industrial equipment, the project is unlikely to succeed because we did not take into account the social context of the operation to be a co-construction process between all partners. In education, teachers are often the victims of “inventions” of educational technologists who are so quick to implement their new systems. Fortunately, the project creates controversy in Quebec and the public debate has been launched.
