Do professors have to cite references in their Powerpoints? And what if data is manipulated to make PPT more "current"? When I was taking my gen-ed classes for nursing school (anatomy, microbiology, etc), I could go to the end of the professor's Powerpoint and click on any of the references if I wanted to find out more information about a subject.  

When I got to nursing school, I discovered that their Powerpoints were a disaster. When I click on "file" in the Powerpoint, I see that the Powerpoints were originally created by another faculty member as far back as 1998. No one has updated the textbook pages referenced within the PPT to reflect the current textbook (very frustrating when you're trying to study for a test). No new drugs or conditions have been added. We're getting 1998 information.

I also  noticed that some of the "facts" listed in the Powerpoint were changed to 2016 or 2017 (example: "According to a 2016 study, 1 in 10 nurses will be subject to violence from a patient."- a completely fabricated "fact").  Bored in class, I ran a search on the "facts" and discovered that most of them were either made up, or if they were true, the date had been changed so that the Powerpoint appears to be current.  There are no sources listed at the end of any of the Powerpoints.

I complained about the textbook pages in the Powerpoint not matching the current text, and received a "disciplinary memo" in my file because my email was considered "incendiary", even though it was factually written and non-accusative.

When we write papers, we as students can be expelled for plagiarism or lose the grade if we invent facts or fail to cite sources correctly.  Shouldn't instructors be held to the same standard?
The situation you are describing is not very pleasant. I try to cover most aspects in order of appearance.


First of all, everyone citing work must reference it (including images). It is not just helpful for you as a learner to find the original material, but also a legal liability.
A ppt creation date or author is not a helpful information source. The date of the most recent change and most recent author might be helpful, but maybe the ppt style (corporate design) was created long time ago by the named autho. I just checked one of my very recent ppts which was created 2011 by a person I don't know - and I created every slide in it by myself and it was updated very recently.
If the slides do not reflect the current textbook you are recommended to use it might be on purpose (which would allow you to ask why this is the case) or just lazyness of your teacher - which is just frustrating since you can not force them to update their slides. It the later is the case, try to compare the content of slides and textbook and try to figure out which information is true (or more relevant) - sometimes slides are only an excerpt of a textbook to reduce complexity. This allows you to make the best out of a bad situation.
If there are really made-up facts in the slides, this would be a matter of academic misconduct. You should be very sure about it and if you are, report it to a person responsible for academic misconduct. Every insttution should have one.
The fact that you recieved a "disciplinary memo" is disturbing. At my institution we are glad if students bring up issues with lecture materials and we try to improve constantly. If this is a generally accepted behaviour a your institution, I would consider finding a better place to study. If it's only one teacher, I would recommend to swallow it and move forward, you did your best to improve the situation and if they don't want to improve, you can not force them to do so.
