Learning Acoustic Assessment of Voice: An Action Research-Based SoTL Project

Abstract

The purpose of this action research, scholarship of teaching and learning study was to develop and integrate effective, student-informed teaching methods for voice acoustics instruction in a graduate speech-language pathology voice disorders course. An online focus group was used to determine what aspects of voice acoustics to include in the course as well as how these aspects were to be covered. A blend of face-to-face, technology-assisted, and practice-based teaching/learning activities resulted from the focused group and were employed in the course. An open-ended application question was used to measure student learning regarding application of voice acoustics to the understanding of human voice. A summative assessment of student recall and application of voice acoustics to speech-language pathology practice was also administered. Results showed significant, positive change pre- to post-course on the open-ended application question. Results of the summative assessment revealed that the largest distribution of student scores was in the 90%-100% range. While individual classes in different programs will differ, this project provides instructors with a baseline format from which to work to tailor acoustics instruction in their own classrooms.
