OnlineTesting is a web-based testing system used since 1998 in several courses, but primarily in the senior level educational statistics class. This class typically has nearly one hundred students in it and OnlineTesting has allowed the instructor to robustly test complex concepts such as calculating stardard deviations and correlations, creating box plots, graphing data, etc. with large amounts of partial credit available. In addition, the grading system allows the instructor to easily review large amounts of data for many students and make adjustments to automated scoring all in a short amount of time. OnlineTesting was co-developed by Arlen Strader http://strader.cehd.tamu.edu/ strader@tamu.edu Dr. Bob Hall http://bobhall.tamu.edu/ bobhall@tamu.edu Home
