This book provides a series of instructional resources, at the aptitudinal, cognitive-strategic, and affective-motivational levels to be applied in the classroom. It integrates in a single text some techniques, programs, and instructional procedures that the participating authors consider relevant for educational practice, and which are very useful tools for the professionals involved in educational intervention. To achieve this purpose, several professors from various universities have developed a conjoint proposal. Starting from the main research tendencies in educational and instructional psychology, they have systematised this research-derived knowledge, making it both practical and useful.
