One day's international scientific meeting is worth a million labs... (of the smokin'-hot-new-science variety). Going to the entire meeting would be equivalent to an entire grad-level course (3 hours *14 weeks). It's [When and How Long]. I don't know if all week is appropriate for our students, but I'm trying to give a sense of the massive learning potential there.
Those costs are for a week of meetings. There are only guest (one day) and full registrations. I will attend the entire meeting, but I haven't decided how many days to offer for the students. My research students gladly went for all the days and crashed on friends' couches. As expected, some of the students became pretty saturated after a few days. It would be different as "requirement" for a course.
I'd still love to get them there somehow, for some amount of time. It's a rare and great opportunity for them. I argue that it is fundamentally different from other undergrad-driven data meetings. The field of [My field] is changing SO FAST right now with the advent of new tools, [Special Programs], etc. that even our brand new text is out-of-date. Sitting in [Adv. Course] will teach them about the last 20 years of the field, going to the meeting will teach them about the NEXT ten years, the years they will participate in.
