case0402

Educational researchers randomly assigned 28 ninth-year students in
 Australia to receive coordinate geometry training in one of two ways: a
 conventional way and a modified way. After the training, the students
 were asked to solve a coordinate geometry problem. The time to complete
 the problem was recorded, but five students in the &#8220;conventional&#8221;
 group did not complete the solution in the five minute alloted time.
