This educational text is a guide to achieving a positive attitude of mind in all circumstances of life. This principle pervades the whole Montessori system, which its founder, Maria Montessori, saw as applying not merely to nursery schools, but to the whole of education, from birth to maturity. Montessori's idea was to transform the process of children's education in order to transform the attitudes of the adults which they would later become, and so those of society and the world at large. In her writings, Montessori proved the effectiveness of such an approach at the pre-elementary level, which is the work for which she is most widely known. This text sheds light on what is less well known about Montessori's educational philosophy: that she also strongly encouraged other educational leaders to extend this method to the higher levels of education. The purpose of this book is to elucidate this vital aspect of Montessori's life work and show how it applies to real-life teaching situations. The suggestions put forward in the book apply chiefly to schools for children aged six to 12, but the main guidelines apply even to those in older age groups. The author shows how the Montessori principles of positive education continue to be valid in the years following pre-school.
