This study was conducted in an attempt to identify any predictor or combination of predictors of a beginning typewriting student's success. Variables of intelligence, rhythmic ability, musical background, and tapping ability were combined to study their relationship to typewriting speed and accuracy. A sample of 109 high school students was pretested using the Seashore Rhythm Test, Digit Recall Test, and the Tapping Test. The students were then posttested at the end of the first semester of instruction to obtain speed and accuracy scores from an average of three three-minute timed writings. Additionally, the motivation control variables of assignments completed and absences were introduced into the analysis. A least-square stepwise multiple regression analysis was employed to analyze the data. The stepwise results indicate that the motivation variable, assignments completed, was the most significant factor in predicting typewriting speed. Beyond motivation, the Tapping Test had a significant zero order correlation with speed. No predictor tests used in this study were able to predict typewriting accuracy. Analysis of the data obtained supports the possibility of predicting a student's typewriting speed based on motivation and the Tapping Test, the predictor variable. (Author/KC)
