Abstract
In this 50th anniversary of the Jean Piaget Society, we have been asked to celebrate The Having of Wonderful Ideas and Other Essays on Teaching and Learning (Duckworth, 2006) – winner of the 1988 AERA award for outstanding research contribution in the areas of teaching and teacher education, now in its 3rd edition, published on four continents, in 7 languages. We have taken the name that Inhelder gave to Piaget’s research method – Critical Exploration – as the basis for the name of our approach to teaching – Critical Exploration in the Classroom. In this paper, we talk about what that name and this book mean to our teaching and to constructivism. Each one of the four authors has written one section, allowing us to present several different aspects of the book.
