This one page overview on Alfred Adler includes information on him (background), his beliefs, and this theory of superiority and inferiority. It also includes a picture of Adler. Works cited / reference section is located at the bottom of the page.
This is a good handout to use when discussing personality theories in psychology and it is appropriate to use for the different levels of psychology (regular, honors, AP).
When teaching (especially the honors and AP classes), I prefer to accompany this handout from parts of Alder's book (The Science of Living), specifically pages 102-116. I prefer a socratic seminar or a class discussion on this topic. Also, see the personalities theory essay as a form of assessment.
