Creative teaching cannot be explained via a few key sentences. Therefore I am giving you the link to this very indepth website that will educate you on all the components within the framework of creative teaching.

If after going over this site you now have particular questions about creative teaching, please do not hesitate to post it and I will address your concern.
I hope this is helpful!
