DEP 2002 is a discussion-driven rather than lecture driven course. Therefore, it is impossible to provide a guide of what took place during any given class period.
However, during the first few sessions on each topic there is usually more lecture material given rather than discussion that takes place. Commonly, the lecture is guided by materials that have been read by the students, including the textbook or articles that have been supplied in advance.
I commonly use powerpoint from my lifespan development course (which is more lecture oriented) to provide visual representations for certain topics. If you have to miss a class, you may want to look at the Lifespan Development lecture page (DEP 2004 Lectures) for an idea of the type of material that may have been discussed during this class period.
