Two experiments were introduced in our senior modern physics laboratory to acquaint students with methods of doing complete experiments. In the “design” experiments, students individually chose, planned, designed, and listed all the apparatus, methods, and people required for a real experiment that might take several years to do. In the “ingenuity” experiments, students individually chose, planned, acquired, built, and assembled the apparatus for a relatively simple experiment and analyzed their measurements. We tested, by special laboratory examinations and other methods, if the half-class of students who had done these experiments were better than the half-class that had not.
