Essays / How Do i write an academic essay (I write like a journalist..) [4]

I am having trouble with my writing,

I used to work in the media so write like a journalist, now I am doing a course which means that I have to write academically, how do I do this? i keep getting feedback from the tutors that I write like a journalist and need to greatly improve but have no clue where to start.

any help would be appreciated
