pyoudeyer · x · 2026-07-15
This post reports the experimental results of ZPDES:
- Students continued to achieve success even as the objective difficulty of the exercises increased.
- This effect held true across students of different initial levels, measured by Elo.
- The author views this as an indicator of "impacting equity."
- Additional context notes that when using ZPDES, most students progress in the majority of activities; whereas with playlists, many students disengage.
Overall, it highlights a more stable and broadly applicable instructional design outcome.
