DSST Lifespan Developmental Psychology: Study Guide & Test Prep. 23 chapters in DSST Lifespan Developmental Psychology: Study Guide & Test Prep. Research Methods and the Study of Life Span.
I have taught (and taken) courses in Child Development and Lifespan Development with numerous textbooks, and this was definitely my favorite. The text is exceptionally thorough and includes a balance of theory and application. Relevant research is discussed throughout, in a way that is interesting and engaging and emphasizes the importance of scientific rigor in studying development.
Most of all I appreciate the personal, direct voice of the text, as if I am listening to the author talk. Some other texts actually make reading about lifespan development boring (hard to do but can be done!) This one very effectively illuminates how fascinating it can be. My only criticism might be that I found it very difficult to cover the entire text in a one semester class, precisely because it is so rich in information.
