Don't know if there's any demand for this, or if people think there's already a place for it, but a forum for chemistry teachers and lecturers could share practical tips would be incredibly useful.
The general rules on this forum, regarding students and citizen scientists are 100% correct for those forums, but I would envisage this forum being slightly different in that more specific advice would be given in how to do things. If someone can't get a practical to work, and someone else has experience of it, that experience would be shared. The reason for the rules being different is that it's not a case of a student, who needs to work things out for themselves in order to learn, but effectively to help educators to help their students to learn.
As an example, I moved to Cyprus 7 years ago, some experiments that work perfectly in the UK's temperate climate are much more difficult to do here due to heat, and more to excessive humidity. Some things I've worked out alternative methods, others I'm still struggling with. We could help each other.
(I've currently got my class 12's nickel sulfate evaporating in an incubator with a pot of calcium chloride as a drying agent as I know from experience they'll never crystalise here on the open bench as they do in the UK!).
It's not just geographical problems though, anyone teaching for a long time will have found methods that work a bit better than those published, or worked out completely new ways of doing things, or practical ideas that aren't even published. It would be good to have somewhere specific to share these for mutual benefit.
