According to your textbook, putting a subject heading at the top of each research note you take will help you organize the notes when you start to compose your speech.
Each of us are well aware of the heading that we will give to any sort of information or documents which are we meant to create or develop. And for such reasons any heading should be well connected to the information which follows up, as there can be a bit of confusion in the head of a student, professional or any other individual who is reading or studying the piece of information.
Explanation:
While, headings should give a more sense of connection to the rest of the world and should be more precise rather then being too lengthy.
Now, there are different formats provided by the different institutions to cover up all the information that any professional is yet to provide, i.e the oxford format etc.
And then each bit or word should be well placed inside the given paragraph during the composition of the whole set of information created by the professional.
