This semester, I imported a Blackboard shell for one course and copied last semester's Canvas class for another. In both Canvas shells, I have a set of reminder announcements I use each semester, then I add new announcements as the need arises.
In both classes, my imported announcements show up with post dates prior to the semester. For one class, everything shows as the date I imported my Blackboard content. For the other class, my original post dates show up.
Both of these sets of dates are bound to cause confusion for my students. Any tips to fix them?
