3 websites that I commonly use in my IB Psychology course are the following:

http://opl.apa.org/ - this website is great resource for research in psychology and it also allows students to submit their own potential research study

http://jfmueller.faculty.noctrl.edu/100/correlation_or_causation.htm - this website has links to many different recent research studies as well as ideas for how to implement them in the classroom

http://www.nimh.nih.gov/health/index.shtml - National institute for mental health - great resources under "Health and Education" especially for the abnormal psych unit.

My username for the ib_psychintro is ccoakley
