It was a lot of fun and I've noticed those who attended have really picked up in discussions to me as well as to each other. Who knew?For me this was a friendly reminder that personal contact is a nice addition to a course where possible and appropriate. I wouldn't recommend it for every course and we can't require a real-time field trip, but it is still an interesting alternative to offer students.
An alternative way to add some interest to a course is to use a guest speaker. We have a stipend to offer guest speakers ($50 per section). You are welcome to try using a guest speaker at any time.
And while we are adding interest to courses.... I know many of you teach for more than one college and are probably looking for easy ways to share content across those courses. Slideshare will now allow you to sync audio files with your slide show. For more information see Alan Levine's CogDogBlog.
