A multi-media, computer-based method for stroboscopy rating training

Methods of training individuals to rate stroboscopic examinations vary wide ly in rating criteria, viewing times, samples, and length of training. Cons equently, problems occur in both inter- and intrajudge agreement. Computer- aided instruction (CAI) provides a means to integrate and control key learn ing factors that facilitate learning. This study attempted to determine if CAI could train individuals to make accurate and reliable visuo-perceptual judgments of stroboscopy. Experienced and inexperienced subjects rated 45 s amples before and after training. Following 4 to 5 hours of CAI training, t he subjects with no previous experience demonstrated improved interjudge ag reement with a panel of expert raters. The training was not effective for t he experienced group. Regardless of the rater's experience, the parameters that required evaluation of movement were more difficult to rate than those requiring only an assessment of structure.
