Describes the intonation visualizer, a machine which permits a model sentence to be presented aurally to a student who sees simultaneously the intonation pattern being traced on an oscilloscope screen. The student then repeats the sentence and sees on the screen the intonation curve that he is generating. (Author/CFM)

The effectiveness of an educational program in decreasing utilization of the prothrombin time determination as a routine admission laboratory test by house staff physicians at a teaching hospital was studied. The results emphasize the need to measure the long-term outcome of educational programs aimed at modifying the clinical behavior of…
