What you need:

If you want to use information you heard in a class lecture or presentation, you need to cite that just like you cite any other outside source (even if your paper is for the same professor!).  How you format your citation will vary, depending on the style you use.  But there are some basic elements you will need.  We're going to use a made-up example to illustrate how it works:

 

PROFESSOR/LECTURER:  Jill Smith

LECTURE TITLE or SUBJECT:  Jane Austen's World

COURSE TITLE:  19th Century Fiction 

COLLEGE OR UNIVERSITY:  Oregon State University

COLLEGE OR UNIVERSITY LOCATION: Corvallis, OR

DATE:  October 22, 2014

 

Examples

 

MLA Smith, Jill. "Jane Austen's World." 19th Century Fiction. Oregon State University. Corvallis, OR. 22 October 2014. Lecture.
APA In APA style, class lectures are treated as personal commuication, which is only cited in-text.  You do not include it in your reference list.
