Sharing resources you have created to improve your teaching is not always the easiest step to take. Often times we become very attached to the things we create that we think that others may not use the resource as we originally hoped. This can be a tricky situation especially if you work as a team, or very closely with others. How can you still be a good teamplayer without feeling worried about the fate of your original resources?
I’ve always just shared my resources freely, asking people to at least mention where they got them (and I usually put my name in the footer, too). If you’re worried about people altering your work to your detriment, give them a secure pdf instead of a Word doc. But I’ve been doing this for 10 years and it hasn’t come up as a problem yet!
So: Share, share and share alike!
