Caleb Gattegno began work on The Science of Education series of books in 1940. After decades of research and real-world experience teaching all kinds of students to read, write, and do mathematics, he released The Science of Education Part 1: Theoretical Considerations in 1987. This book is renowned for its deep consideration and enlightening conclusions about the problem of education, but it is also a notoriously challenging read.  I have decided to take on the challenge, and to summarize each chapter according to my own understanding. I hope to express his ideas clearly and succinctly, without losing the powerful concepts his original words evoke. My next post will be summarizing Chapter 1: How a Science is Born. Wish me luck!
