Once you have a baseline assessment, you can use it as a reference point to track your students' progress over time. Different methods and tools can be employed to monitor their improvement and challenges, such as recording their sessions and comparing performances over time. Audio or video recording devices, apps, or software can capture their vocal output and analyze changes in pitch, tone, volume, articulation, and expression. You can also share the recordings with your students and ask them to self-evaluate their progress. Rubrics or checklists can be used to rate their skills and performance. These measure specific criteria and indicators of vocal proficiency, such as intonation, resonance, dynamics, phrasing, and style. You can involve your students in the assessment process by asking them to rate themselves or each other. Milestones and tasks can be set to measure their achievement; these challenge your students to demonstrate their skills and knowledge in different contexts and situations. You can use them to assess your students' competence and confidence in applying their vocal techniques and strategies.
