The Predictions Table (PT), a tool for determining students' knowledge, is described. The PT is a matrix consisting of a group of variables and a set of time periods. Students enter in the PT their qualitative predictions of the effects of a perturbation on a physiological system. ⋯ Also, students who worked in groups had significantly greater improvement than did control students. Using CIRCSIM also significantly reduces the number of relationship errors that the students make. They made even fewer errors when an instructor was present in the computer classroom while the students used CIRCSIM.
