Can I use the same clip of the copyrighted work in a later class session?
Yes. Consider this example. I am teaching in distance education this semester. In September I used a film clip, consistent with TEACH, and I left it on the server for some short duration of a “class session.” The students can no longer access that session. Today is November, and I want to emphasize a point and show once again the same clip. The TEACH Act does not bar the reuse of the same clip in the context of a second class session, whether you are reinforcing an earlier point or making a new point from the same work.
