This is nice activity that you can use at the beginning of the year in any level psychology class. There are two worksheets to be printed out. The first one has a summary of Billy and his upbringing and a series of questions. The second has a list of the various psychological approaches. I hand out both worksheets to the students and have them get into groups of 2 or 3. They read the summary and then proceed to analyze Billy using the approaches. We then discuss the outcome.
