Am I able to use points from my lecturer's Powerpoint presentation in my essay, and if so how do I reference it?
Whether you should use a lecturer's PowerPoint presentation (or lecture notes or handouts) as a source is something you should raise with your lecturer, as it may depend on the nature and requirements of your assignment topic and the expectations of your lecturer.
Lecturers usually expect students to refer to scholarly publications (mostly books and journal articles) when completing assignments. Lecture notes and PowerPoint presentations would not normally be considered scholarly publications. However, there may be occasions when it is appropriate to use these sources.
If you do wish to reference a lecturer's PowerPoint presentation or other notes you should refer to the University's Referencing Guide (see link below) and select the referencing style (e.g. APA or Chicago Footnotes) and then the 'Multimedia' tab.
Here is an example of how you can cite a PowerPoint presentation in the reference list using APA style:
Kaplanian, C. (2015). Attributes of the counsellor: Personal and professional, lecture 3. [Powerpoint slides]. Retrieved from https://learnit.nd.edu.au/webapps/blackboard*
