Please help me

Hello everyone,
I am desperately searching for the title and author of a piece of literature that begins "If you treat a child with ..... then he will learn......" I really want to find this poem and have been unsuccessful. I would really appreciate any input.
Thanks, Pam

I actually know what you're talking about because I had it on my wall when I was little but I can't for the life of me remember what it was called or exactly how it goes and a google search didn't help :(
