Use of 'Rather' before noun: This is rather...

[Tom]

Hi

Could you please tell me if the use of the word rather correct in the given sentence? Is it there for emphasis?

1- This is rather the content of the lesson, not how you plan to teach it.

Hi Tom,

I don't like the use of rather in your sentence and would use more like instead.

Many thanks, Alan

OK, I would use more like in the given sentence instead of rather.

Just one question: Is it grammatically incorrect or grammatically correct but odd?

Hi Tom,

It's not really a question of grammar - it just doesn't make sense to me!
