In my opinion, the most interesting aspect of Module 4 is the concept of stealth assessment. I believe the traditional way of stopping a lesson to give a test is dead in the water for online learning; instead, we should be using the simulation itself to harvest "evidence" of a student's mastery in real-time without breaking their immersion. By applying Evidence-Centered Design, we stop treating games as "extra" activities and start treating them as sophisticated, data-driven platforms that provide a much more honest picture of a student's true capabilities than any multiple-choice exam ever could.
