My student doesn't want to write sentences but I am going to make her do it anyway.
Why would you make her do that?
She'll learn how to think for herself
You should make learning a little more fun for them. You shouldn't force her to do things like that.
I can tell she is thinking three sentences ahead of herself. She just needs a little push.
I can understand that you want your students to learn at the same pace, but this one clearly is uncomfortable with writing what you want, so why not pull it back a little bit? You may think pushing her is a good idea, but sometimes that pushes people away.  Surely there are other ways that you can motivate her?
