A Reverse Hawthorne Effect in Educational Evaluation
Zdep, Stanley M.; Irvine, Sidney H.
J Sch Psychol, 8, 2, 89-95, Spr '70
In an evaluation of the effectiveness of broadcasting media in education the control class achieved higher posttest scores than the experimental classes. These results suggest that when experimental and control classes are housed at the same location, teachers of control classes may and can motivate their students so that their classes no longer provide a valid base line to which experimental classes can be compared.
