One novice subject's learning about the tennis serve was measured (over a 4-day period) by recording the subject's gestures and verbal remarks. This case study compared gestures, verbal remarks, skills, and form data to see which types best discriminated between days 1 to 4, and it also attempted to determine if discriminant analyses were suitable for such comparisons. Verbal data selected included: subject's evaluation of a serve, part of the serve described, and number of items the subject referenced. Gesture data selected included: body part used in the gesture, size of gesture, type of gesture, and number of gestures per serve. Results showed that generally gesture and verbal data appeared to better discriminate among days of early skill learning than did skill and form rating data. It was also found that the use of both contingency table and discriminant analyses is valuable. (Author/JMK)
