Our goal has been to provide a foundation upon which teachers can build a successful course within any school's schedule. Thinking About Psychology has 14 traditional chapters, but they have been divided into 34 modules written to stand independently from one another. Chunking the material into these shorter modules helps sustain student understanding and interest, and provides more flexibility for structuring your course. Student understanding of later modules does not depend upon reading the content of preceding modules. - Preface.
