I work extensively with teachers and support staff to bring about changes in approaches for learners with ADHD. It's inspiring to see so much good practice, particularly when there's a willingness to share.
Here are some interesting strategies for managing behaviour issues, collated from a recent training event. The behaviours are consistent with ADHD and some really good ideas were offered:
Behaviour: Angry with him/herself – fluctuating emotions
Behaviour: Calling out inappropriate comments in class
