Thanks for taking the time to respond, I really appreciate it!
Andreas resolved my tech difficulty on the tracker item - I had added one too many page breaks (in my enthusiasm!), and broke the activity as a result. Once that was fixed, the Feedback file worked beautifully.
Beyond the tech question though, I guess I'm asking are there any other folks who would consider bending Feedback in this manner a good idea?
In my consulting work, I find folks often get frustrated with the clunkiness of Lesson (even though I think its a great tool), but Feedback is a little quicker and easier to setup. Unlike Lesson, Feedback has an option for us to display responses, anonymised or identified, back to the students. I think sharing responses after the student has made their own personal choices could be a good tool for more reflective practice. I also think one of the challenges facing online learners is feeling isolated and unsure of whether they're on the "right track" in the activities.
I'm currently working on a mock up of a Feedback activity to share here, but it will probably take me another day or two to get it in good shape. Hopefully, a file can demonstrate what I mean!
Thank you again, will post more asap.
