While fair use includes uses for teaching, scholarship, and research, you still must consider the four factors of fair use.
In particular, the effect on the potential market must be considered. For instance, copying parts of a textbook to distribute to members of a class would affect the market of that textbook, which normally all students would have to purchase. This copyright would not be considered fair use.
Use the checklist on the page linked above to weight all four factors of fair use when deciding whether a use is infringement of copyright.
