Can you give me an example of what you look into?
2:06
Yeah.
2:06
So, um, one of the techniques that I've worked on and published on is actually kinda importing a technique from the, the field of educational data mining, which is, which is more broadly, like, how do we understand learner data in, in all kinds of technologies, where we look at what we call learning curve analysis.
2:21
So there are ways of taking player data and essentially annotating within a game or within a, a other kind of instructional environment what kinds of skills, what kinds of knowledge do we think pieces of the game leverage.
2:33
And then looking at a trace of a player going through that environment and seeing, it's like, well, if these are the knowledge involved and this is how they're improving or not within the game, then they're probably learning this set of skills, for example, and you can plot that over time.
2:46
So essentially, over your opportunities to practice something, are they reducing an error or improving in success? It's kind of the same thing.
2:53
And you can actually empirically plot the curve of learning against a particular set of skills.
6:00
How true is that? And are those educational games analyzed with a system like yours?
