Links to Calculus Flash Videos

A few people asked if I would create links to some of my Calculus videos. I use a variety of software to produce the videos… Camtasia, SnagIt, TI-SmartView, the Internet, Wolfram Demonstrations, PowerPoint, and whatever else happens to be helpful at the time. I’ve selected three of them (pretty much at random) for you to see. Please keep in mind that these are not “professionally produced” … I do not have time to go back and edit a word if I misspeak (although I could with the software I use, I just don’t have time… it’s hard keeping up with online calculus). These video lessons are my version of what takes place in the classroom, and just like on a whiteboard, I may occasionally make a mistake and correct it… well, hopefully I correct it! 🙂 Using Secant Slopes Limits and Vertical Asymptotes The Falling Lexus Example Before you watch the Falling Lexus Example, you ought to watch the “Falling Lexus Commercial.” The files are all zipped. When you unzip the file, choose the LARGEST file (the swf file) to run. You will need to have a Flash Player downloaded to watch. [Update 5/6/12: My videos are now all loaded on Screencast.com, recorded live with a Tablet PC, and produced with Camtasia Studio as an MP4.  I’m leaving this post here for perspective.] Possibly Related Posts: Group Exploration in...

Keeping your Online Classes Straight

If you’ve ever taught several different courses in the same classroom, you understand the problem. At some point, all the classes start to blend together until you can barely remember who is in which class or what you’ve said where. This problem seems magnified for online classes, as you do not see the faces of your students when you are “in” each class and there is, therefore, no visual cue to keep them straight. So, as I am teaching three classes with major online components this fall, how will I keep them straight? I especially want to avoid posting the wrong assignments or announcements in a class. I decided to give each class it’s own unique look, with a different banner and different buttons so that when I am navigating the three classes, it is obvious which one I am in by the color schemes. The result of my customization: Here are my three classes with their three schemes: Possibly Related Posts: Learning at Scale Slides from ICTCM The Importance of Findability for Learners Why prototype a digital course?

Playing with Avatars

Well, I’m trying to get my Online Calc class up and running this week and at some point I became obsessed with getting an avatar to make the announcements in the course. Why use an avatar? Let me tell you a story… When I was in 8th grade, I took Geometry from a guy named Mr. Allison. He had the most bizarre colored pants (to this day I can still remember Mr. Allison’s famous red pants). Every day, it was worth it to go to class just to see what color his pants would be. As a consequence, I never missed a day of class and I really did enjoy learning from the guy. My current thinking is that if the avatar changes pretty often, the students will at log in to class often just to see if the avatar has changed. Then, when they see the avatar, it will remind them out loud (in 60 seconds or less) what is about to be due or any other important announcements (“schedule your next test” comes to mind). Is that silly? Yes. Might it work? Also yes. It could. (Really… have you tried it? Can you tell me for sure it won’t work?) So, all evening I’ve been experimenting with the avatars on SitePal. The only major problem I’ve encountered is that all the female avatars are pretty “busty.” I...
