The basic elements to formulate and execute are provided. The focus is the development of thought, that is, teaching how to learn, think and create, as the subtitle states. The book is divided into two units and a total of eleven chapters. In the first unit, the basic teaching strategies of the different levels of thought are developed, with the corresponding technical aids. In the second unit we expose the main teaching methods and techniques, with a constructivist emphasis, paying special attention to the so-called active methods and techniques. We hope that this book is really useful for teachers in their daily practice, and that it contributes to a better understanding of the new approaches, towards a new paradigm in teaching.
