Final answer:
Research regarding video feedback's effectiveness compared to knowledge of results (KR) is not definitive, with studies suggesting that it may be more effective with additional cues and its value depending on contextual factors.
Step-by-step explanation:
The question addresses the effectiveness of video feedback compared to knowledge of results (KR) feedback in learning environments. Research is not entirely clear-cut on whether video feedback is superior, but it is understood that video may be more effective when paired with additional cues. The studies referenced note the variance in feedback effectiveness, indicating that there is, indeed, some contention in the academic community about the best practices in feedback methods. For instance, variability in 360-degree feedback, as discussed by Tornow (1993b), may result in valuable learning discussions among employees and supervisors, potentially enhancing effective learning on the job. This points to a more nuanced understanding where the context and additional support can influence the effectiveness of video feedback.
