I was always taught not to say things like "this essay will outline the blah blah blah" and I've gotten points taken off for not doing that! I was told to construct your introductory paragraph with the last line or two being your thesis statement and then following that you PROVE your point.
I would have failed in the states if I had said "I propose" or "I would submit"! We were told to speak with the language of authority!
I don't know if this is just my professors or what, but it was a shock to me.
I was taught the same things...
but as I went on in University land it changed...
Speaking as a former journal editorial assistant.....This is pretty standard academic writing practice in the USA and UK. Once you get over the 5 paragraph essay format from US High School and early University years it does switch over. The point being that the longer your papers get and the more involved and subject specific, your reader needs to know right away if there is anything of value in your piece. So you have to pretty much give in your intro paragraph: what you are proposing (usually using the lovely one, this author, this study instead of I), what your hypothesis is and just why does the reader care ie what contribution are you aiming to make.
If I don't see these these in a peer reviewed article I don't bother going through all 20+ pages. I should be able to get your main points from just reading the intro and conclusion.
It might help to check out some of the academic peer reviewed journals in your field to see what they expect. Especially if that's the standard your tutors are using to grade you by.
Also my university requires that my doctoral thesis and any work follow the norms of British Academic English and punctuation. So my husband reads/will read anything I hand in.
It's not wrong... it's just different.
One (it's like the royal we isn't it?) also must endevour to find a balance between the very passive voiced academic paper and the active voice that keeps people interested.
Oh and make sure you use whatever citation system your department or even your professor likes. This alone can send academics into a tizzy.
