As I was finishing up my lecture for tomorrow, a most intriguing segment aired on All Things Considered. The issue was an ethical question over whether someone is ethically okay to design and base a large part of their material for an on-line, for-profit course on someone else's textbook. The course designer properly cited the work (and consulted other sources as well), but never obtained the textbook author's permission.
I have been writing my lectures based heavily on the usual professor's outline and relying on 3 books for my references and figures. One of those books is the assigned textbook for the course, and I assume I'm in the clear on that one. But the other two books aren't always getting cited on my powerpoint slides (although they are cited in the notes that I see in the powerpoint file). Am I okay ethically?
I've also been getting some images from the web (yay, google image). I've been trying to acknowledge on the slides any images from individuals or corporations, and mostly I've been trying to get them from .gov or .edu sites, where at least for the federal government things aren't under copyright.
I guess I'm wondering where the line is in terms of powerpoint lectures. Should I acknowledge each image on each slide? Should I add a slide on the end with all of the image credits? How do I acknowledge that I am borrowing heavily from another professor? Any suggestions?
