If I use information from my professors lecture in my paper, do I have to quote it?

Answer 1

In my opinion, it depends on the type of paper you are writing and if you are quoting their lecture directly, paraphrasing, or just using the general idea. Quoting or paraphrasing usually require citation but using general information that your professor gives you is fair game. Ask your professor or look at your syllabus if you are not sure because your professor may be strict about his/her paper writing policies.

Answer 2

A quote from a medical journal referencing the policies on submissions.

"Avoid citing a “personal communication” unless it provides essential information not available from a public source, in which case the name of the person and date of communication should be cited in parentheses in the text. For scientific articles, authors should obtain written permission and confirmation of accuracy from the source of a personal communication."

I would suspect your lectures might count as a personal communication. So I suspect that it would be considered as bad taste to quote him unless he mentioned some of his material as original works, since most of his lectures would be based on books, articles, scientific journals and it would be expected that you would discover that in your research.

Answer 3

If you have his quote exactley as he said it in your paper you do need to give him credit. But if not no
