I have a student who sends me emails twice a week showing me his updated dissertation. At first I supported him a lot. But he literally does what I say word by word and never goes beyond what I tell him in doing further research. I have been clear to him that his limits are the sky. But when he adds a small detail he sends me an email again asking me if that was okay or not.
I think he assumes that he will take a very high mark if I did not tell him exactly what he needs to do for his dissertation. I am a bit worried about how to reply to this student. As I am trying to be polite and nice and I do not want him to fail, but at the same time I need to be genuine.
Please give me advice on how to reply to such kind of students so that I do not offend them. I want to convey that I encourage them to do further research and it is okay to say something I disagree with as long as they support it with proofs and evidence.
