Summer of Math Exposition

I think that the subject could be made more interesting by making it more abstract, also stating when is the solution unique or what is the space of solutions. I would have expected a more theoretical approach to all this with at the end a practical approach to finding one solution.

To slow to explain the basics ideas. Video ends abruptly without a wrap around explaining pros and cons of the method exposed

The solution presented in the video didn’t seem to offer a new perspective on the math involved, and would probably be the first method thought of for solving it intuitively. I think the explanation could make much more sense if it were contextualized more as a programming solution than a math one. Separating when you’re recording your voice over and when you’re creating your visuals would improve the viewing experience significantly.

I'm not sure what the motivation is. I understand the context, even though I've never seen a school compute average that way. It's possible it's just not a practice where I come from, and my schools were using weighted average instead of duplications. It was clear, and it's novel for me, but I don't think I will remember this video very much. It is even more true, because at the end the solution isn't unique. I appreciate knowing that's the case with the method proposed, and I thank the video for making it clear, but that should be solved with a clearer notation system.

This is a very clear, useful explanation of a method for solving a practical problem. The video itself is visually bare-bones, but I do not think that the core content of the video would be better communicated with more elaborate visualizations. This video is a good tool for someone trying to solve exactly this problem. To improve the pedagogical content of the video, it could be useful to make the video about tree diagrams more generally. What I find most interesting about this problem is 'what characteristics of this grading method make it suitable for reverse-engineering through a tree-diagram?' I think understanding tree-diagrams and recognizing what sort of problems they can be used to solve is the implicit pedagogical core of the video. I would like to see that core made more explicit through the narration.
