Evaluation of three different types of feedback.
| Written | Audio | Video | |
|---|---|---|---|
| Cost | Low | Relatively Low | Moderate |
| Time | Time consuming for detailed feedback | Reasonably time-efficient | Time consuming if editing rerequired. |
| Affordances | Provides permanent record. Allows detailed feedback. Easily integrated into LMS. | Conveys tone and nuances. Supports feedback literacy. Can be transcribed using Text to Speech software. Accents may be difficult to interpret. | Combines audio and visual auditory elements. Allows visual demonstration/feedback. Can have automatic closed captions if using systems like YouTube |
| Limitations | May lack tone and nuance. Less engaging. Can be less effective for those with LLN limitations. | Not suitable for hearing impaired (unless closed captions used). | High technology requirements on assessor and candidate (to record and view respectively). May provide material that can be used to generate deep fake video. |
| Incorporation | Use within assessment result (summative) feedback under ISO17024 system. | Could be a good option to give feedback to candidates on their radio procedure (i.e. how to use callsigns, pronouce the phonetic alphabet etc). | Could be a good option to provide a skills exemplar (i.e. how to tie a knot) so that students can learn and prepare for future assessment. |
