It would be good for me as the educator to know what my students are struggling with. All I can see are the dates that my students complete assignments. Are there any plans to introduce more statistics, so that I can know which words or concepts are giving my students trouble? At the very least, it would be good to have a time metric. If I knew how long it took for the student to get through the lesson from beginning to end, that could be helpful. But more information would be better.
If I know what my students need, I can send them an email offering help. Otherwise, I'm blindly asking them what they need and hope they're honest with me about it.

Duolingo does not provide that information.
