OFFER TO IMPROVE OTHERS (Presentation skills)
A genuine collegiate support for presenters can be the clear and unbiased feedback offered to them by a colleague or professional friend. Offering to evaluate might be a tactic; similarly, the presenter may ask a colleague to assess their presentation.
Oral feedback is valuable and is aided if supported by written comments. These might be critical points, with both methods aiming to offer the presenter a chance to improve delivery.
Part of this should be recognising strengths (offered as commendations) and commenting on arenas needing development (offered as recommendations).
Reflection is supported by evaluation.
