A Scale Assessing Music Student Teachers' Rehearsal Effectiveness

In this study, I sought to construct a scale assessing music student teachers' rehearsal effectiveness. A total of 251 qualified respondents indicated the extent to which each of 54 scale items represented an essential aspect of music student teachers' rehearsal effectiveness. Data were factor-analyzed, three interpretable factors were extracted and obliquely rotated, and, based on their pattern of loadings, 10 items were chosen for each factor subscale. The three factors were Conducting Technique, Teacher-Student Rapport, and Instructional Skills. To examine interjudge reliability, I asked a panel of experienced music educators to use the 30-item Student Teachers' Rehearsal Effectiveness Rating Scale to rate eight student teachers' videotaped rehearsals of secondary choral or instrumental ensembles. To determine criterion-related validity, I compared the adjudication panel's ratings with the student teachers' final performance-based teaching evaluations.
