Hi.  I'm Ed Nelson. 

I teach at Calif State Univ Fresno in Sociology.  Also the director of the Social Research Lab which does surveys (door to door, web, cati, mailed) for different groups.  Also do evaluation studies.  I have been involved in the Social Science Research and Instructional Council which is made up of one rep from each of the 22 CSU's.  Our website is http://www.ssric.org .Take a look at some of the teaching resources on it.  I just posted a set of exercises for teaching critical thinking which I also added to Merlot.
