Q: Is there an app that will accommodate both f2f & remote group collaboration using a PDF file that the group of students (3-4) to a group can all interact with the document as a white board and then submit and/or share that to the group IN person and online possibly.
A: This has come up in other avenues in Yammer and for the collaborative student aspect Google Jamboards and Microsoft One Notes have been what is recommended that have also been approved as Courseware. (Kuntz)
