 I think they're doing critical thinking because this articles we pick as instructors are challenging enough that we're asking them to make connections. We're asking them to question. So one thing we've done, we've, we've teamed up with the philosophy program here. And they have a, so, so Gary Comstock is a professor here. And along with a researcher at Harvard, Nate Odi, they've developed how we argue and how we evaluate and how we evaluate or how we argue, how we argue is available online as a module. And for that 200 level class, we have students as an experiment, we had students do how we argue. First, that six hour online class, and then annotate or then and critically read and some of the questions that came up about arguments about connections. We see them in there, going back to metacognition in their reflections, we see it in their annotations. So I think it's there, even without us having a specific question like, how many genomes did they find or why is electronic waste an issue. They've made the connections, they are critically, not all, but they are critically reflecting on why is this, what's behind the author's use of words here. Is it something I can judge or is it supported by other evidence.
