I wrote something on the same theme this weekend, and just posted it (after getting scooped here!).<BR/><BR/>In a regular semester, I'll usually miss 2 or so classes, and I'll get my grad student(s) or someone else to cover whenever possible. This semester I may miss 4 (cancelling one), and I feel bad about it already. But as I say in my post, there seem to be growing numbers of reasons why I have to miss class...Michael Mitzenmacherhttps://www.blogger.com/profile/02161161032642563814noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-83989426364659393352008-03-04T11:44:00.000-06:002008-03-04T11:44:00.000-06:00It can hurt your tenure case if you do it too much...<I>It can hurt your tenure case if you do it too much. </I><BR/><BR/>There are good and bad reasons for missing classes. Missing classes for a family vacation or a chance to get away early for a weekend is not OK. Missing classes to serve on an NSF panel, to publicize your research via conferences or by giving talks at other universities is more than OK. If you are a pre-tenure faculty member and you aren't skipping some classes for these good reasons then you are making a mistake.<BR/><BR/>There is the classic 'tenure tour' to publicize your research to potential letter writers but it is even better, within reason, to do this all along, if you can. That way, people will learn more than just a single snapshot of your research and it will lower the stress near tenure time. Outside of publicizing your work, engagement at conferences is valuable for obtaining fresh research ideas that will be beneficial to you in the long run.<BR/><BR/>It is more of a mistake to think that you are so essential to your classes that you can't skip them. I tended to think this too much myself. It is important to be engaged and ensure that what is covered in your absence is well thought out so that students don't feel abandoned. In fact, giving your grad TA a chance to teach may be part of their graduate training, which is part of your job, too. Personally, I've found that 10% of classes is a fairly hard upper bound for me to comfortably maintain engagement. Others may have a different sense. {I don't recommend canceling undergrad classes but it is OK to do this for classes aimed at Ph.D. students, who will better appreciate the reasons -- and for whom the cash flow is probably in the other direction.)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-2964752103384056942008-03-04T10:11:00.000-06:002008-03-04T10:11:00.000-06:00For me it depends a lot on the type of class.

For a graduate seminar, skipping one or two classes is much less of a problem. And in either case I'd be much less comfortable skipping for personal reasons (a family trip) than professional ones (an algorithms conference).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-19491038224947265152008-03-04T09:26:00.000-06:002008-03-04T09:26:00.000-06:00$2.5K per class with your math, right, not $25K?Bu...$2.5K per class with your math, right, not $25K?<BR/><BR/>But it's still a substantial amount of money.Michael Lugohttps://www.blogger.com/profile/15671307315028242949noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-72671030939815153042008-03-04T08:17:00.000-06:002008-03-04T08:17:00.000-06:00I try never to miss class.

When, inevitably, there is a class I will have to miss I try to schedule the exam for that day. <BR/><BR/>Of course, the other alternative is to find another faculty member (or your TA) to cover an occasional class you miss.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-24468867699947818022008-03-04T07:46:00.000-06:002008-03-04T07:46:00.000-06:00you just reminded me of how much money I've lost o...you just reminded me of how much money I've lost on some useless courses so far. <BR/><BR/>As you mentioned this kind of calculation is misleading, students may think they'll be better off without higher education. I was just thinking what could happen if I had invested $35,064 every year for the last 7 years (its my seventh year at school). I could be a millionaire :)<BR/><BR/><BR/>Thank for the note<BR/>Sia<BR/><BR/>PS. actually, assuming 18% annual return, the compound growth over 7 years would be $501,000. there is still some hopes!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1622964084059758752008-03-04T07:05:00.000-06:002008-03-04T07:05:00.000-06:00And notify, notify, notify!

It happened surprisingly often, and turned what might have been otherwise considered a nice break into impotent fury. :PJason M.
