I work with about 100 4th graders and only use Lumio asynchronously. I have them record a short passage and answer comprehension questions weekly. I would like a way to end the activity but allow students to see feedback I currently have them turn in a paper with their answers and I provide feedback on their paper regarding their fluency and comprehension. I would like to avoid the paper part. I also don't want them altering their work attempts. I want the students to see progress and growth over time.
