In this book, I expound and suggest a space for reflection, and a thorough analysis which places its greatest emphasis on a detailed review and examination about the knowledge early-childhood educators should have regarding the concepts that define the functioning of the human brain as a fundamental organ in students' lives. On the whole, it involves discovering how we learn, in which ways emotions influence the learning process, and why it is necessary to create enriched environments for teaching-learning, based on contextualized projects. The purpose is to discover the motivation which will enhance skills and competences in young learners.
