Good critical reflection questions are open-ended and usually process-oriented, like the Thiagi debrief (hubicl tool #7).  For online or remote learning situations, an interesting way to gather data upon which to use this rubric (if you are using a web-conference platform to deliver online learning) is to use the chat or Q&A function: post a reflection question or three in your final slide(s) and ask the participants to respond in written format in the chat room. (Most chat rooms will let them choose to either respond privately only to the instructor, or respond to the group.) Then you can save the chat room contributions --see the instructions in your web-conference help guide--and analyze the data using this critical reflection rubric. For additional reflection questions pertinent to study abroad reentry, I can recommend this site: https://sites.google.com/site/engagingstudyabroad3/backhome/key-re-entry-questions.
