• The Psychology of Arithmetic by Edward L. Thorndike. Edward L. Thorndike was an American psychologist, educator, lexicographer, and pioneer in educational research. Thorndike wrote reading and arithmetic books for pupils, school dictionaries and spelling lists, tests, and pedagogical guidebooks and teachers' manuals. This book presents the applications of this newer dynamic psychology to the teaching of arithmetic. Its contents are substantially what have been included in a course of lectures on the psychology of the elementary school subjects given by the author for some years to students of elementary education at Teachers College.
