Below are a couple of comments:
"I was at your ACE presentation at our school on the 23/6. I thoroughly enjoyed it and felt very energised after it in terms of our own projects. ...We are fortunate in being a laptop school that has really good technology access and innovation. However, I think that your presentation provided that overarching paradigm that is sometimes lost in our everyday practice."
"Thank you for presenting such a thought provoking and complex issue for your seminar last night. I am not sure how you fitted it all in, in seventy five minutes but you did. It should be the start of a great conversation at many schools. I would love to have had the opportunity to work with you in a school setting."
"The first part of Andrew's talk with audience participation stimulated thinking. I think it is also time for strategy implementation."
"Congratulations on an excellent thought provoking lecture."
