The biggest challenge that I have seen is that without the face to face interaction, we don't have the common ground to know where the student is at, what their skill level is and if they are getting lost until it is too late. Sometimes, I have seen a student seem to be doing fine, but then tell me that they were lost. It doesn't matter that I have asked every class if they are okay or if there are any issues. They don't seem to feel confident to voice their need for help.
