On the spot
It's a shame there's so little you can cover in an hour - you have to stop just when the students are at their most engaged.
Next time, we'll be going for a two-hour workshop. I think that will be just right. It's been fantastic and I'd like to bring some older students.
But they need more time to really make the most of it. With a two-hour workshop and the exhibition, it will give the students time to really make some progress, and still fit nicely into the school day. It's very reasonably priced too (pound;5.60 for groups of 15 pupils). The parents didn't have a problem with it - and I wouldn't either if it was for my children. It's nothing for what the students get out of it.
