The study established the validity and reliability of a weighted individual performance-based assessment tool within the utility scope of middle school orchestral strings. The following research questions guided this study:
1. What specific string-playing behaviors and corresponding criteria validate a weighted individual performance-based assessment tool for middle school orchestral strings?
2. What are the psychometric properties of the weighted individual performance-based assessment tool in authentic situations?
For Research Question 1, the expert panel and I were able to 100% mutually agree on 10 string-playing behaviors: tempo, rhythm, tone, pitch, intonation, technique, bowing, dynamics, phrasing, and posture that created the DISAT. Being interdependent, these string-playing behaviors are relevant because they encompass every necessary facet of orchestral string performance (Zdzinski & Barnes, 2002). According to Zdzinski and Barnes (2002), an orchestral string performance assessment must evaluate each facet of a participant’s playing ability to rate the overall musicianship. Bergee and Rossin (2019) stated in their research that it is important to have various aspects of a performance utilized in a musical assessment.
The DISAT obtained reliability of 0.872 by having enough variance between raters in the authentic situation. Linacre (2015) stated that reliability greater than 0.8 is acceptable to v distinguish separation between raters. Combined with the expert panel's 100% mutual agreement on content validity, this proved the DISAT to be a valid and reliable assessment tool for individual performance-based orchestral strings assessment (AERA, APA, & NCME, 2014).
The DISAT can be utilized by districts and middle school orchestral string music teachers in North Carolina. Being a consistent, objective tool, the DISAT can standardize our approach to middle school orchestral string music education assessment (AERA, APA, & NCME, 2014). The data collected by the DISAT could easily track the musical progression of students while giving opportunities for constructive, purposeful feedback.
