Just a quick question. I teach some undergraduate mathematics. I like to produce notes that contain exercises.
Sometimes I make my own exercises, sometimes I take exercises from various sources and edit them slightly and sometimes I take materials from the previous teacher.
However just recently I found myself copying a full set of exercises from a textbook and instantly a wave of guilt came over me.
What I would like to know is how do people feel about this? Is a mention at the start of the notes sufficient or should I really reference each instance where I take an exercise... even with page number.
Any opinions greatly appreciated thank you.
I think it is completely fair to use exercises from other sources if you mention it. In an effort to teach and to explain a topic in a better way, sometimes it is required to use examples from other sources.
