Design, Development, and Initial Evaluation of a Web-Based Music Ear-Training Assessment System in Higher Education

Information from the abstract

Online assessment of music ear training requires the coordinated delivery of auditory stimuli, musical response formats, and examination records. In this study, a web-based assessment system for higher education was designed, developed, and initially evaluated. A React interface and Firebase services integrated reusable items, audio playback, a virtual pitch-reference piano, local and cloud response saving, and instructor-controlled grading. The initial evaluation combined a three-expert content review of 50 rhythmic-dictation and chord-quality items with a 12-item questionnaire completed by 101 consenting respondents. Mean item–objective congruence was 0.953. The broad user-evaluation composite averaged 4.30 out of 5 (SD = 0.60; 95% CI = 4.18–4.41; Cronbach’s α = 0.943). Exploratory factor analysis supported one dominant questionnaire factor (KMO = 0.907; Bartlett’s χ2(66) = 1063.49, p < 0.001; 62.65% variance explained) rather than four distinct latent dimensions. Post-review controlled technical testing across 145 trials showed 25/25 successful audio-playback requests, 25/25 same-device recoveries, 20/20 acknowledged Firestore writes, and 20/20 successful final submissions with no duplicate records or scoring discrepancies. These findings provide preliminary content-alignment, user-perception, questionnaire-structure, and selected technical-performance evidence. Examination-score reliability, item discrimination, performance on physical mobile hardware, and learning effects remain to be evaluated.
