Sorry for the error. Here is the correct version:
-----------------------------------------------------
"He is more of a student than a teacher."
"He is more a student than a teacher."
If I want to talk about a teacher that acts like a student, which sentence is standard English?
NOT A TEACHER
(1) I really liked your question, for it really made me think and do research.
(2) This is only my opinion, based on what I have read in Professor George O. Curme's
great book
A Grammar of the English Language.

IF I understood him, you can express that idea in two ways:
(a) He is
more student than teacher.
(i) "more student" is like an adjective. It refers to "He." It's an adjective, just
like "He is tall
er than the teacher." ("-er" really = more. Of course, you cannot say "He is student
er than teacher.")
(b) He is
more of a student than a teacher.
(i) The great professor says that in this construction (kind of sentence), we analyze
"more" as a pronoun. That is why we need to use "of a."
(4) Here are some of his examples when we use "more" to make an adjective out of a
noun:
She is more mother than wife.
She was more woman than they. (You can't say "woman
er")
(5) Here are some of his examples when we use "more" as a pronoun:
Charles was more of a gentleman than a king.
Smith is more of a teacher than his brother.
(6) It is
only my opinion that most native speakers would use the pronoun sentence:
Tom: Do you like our teacher?
Mona: Not really.
Tom: Why?
Mona: Because he seems to be
more of a student than a teacher.
Tom: What do you mean?
Mona: Well, for one thing, he wants to be cool, so he wears blue jeans. I want my teachers to dress like teachers.
Tom: And what else?
Mona: He tries so hard to be friends. I don't want my teachers to be my friends. I just want them to teach me something that I don't know.
Tom: That's right!
Mona: Above all, he doesn't know his subject well. I think that he reads the book five
pages ahead of us every night.
EDIT: I think that many speakers drop the "of," so they might simply say: He is more (of) a student than a teacher. Since you are an excellent learner, I suggest that you include the word "of."
