I need HELP! written response?

Hello All, I have no coding experiencing. I am trying to write my first experiment. I was wondering if someone could give me just a very simple step-by-step walk through on how to allow someone to respond by typing in a word. I also want them to be able to see the word they are typing. If anyone could help, it would be super appreciated as I have no idea what I’m doing!
Thanks so much!
