Amy in the Math Dept. asked me if I could do a presentation for her research group which includes two graduate students, three undergraduate students ( I knew Amy from the New Faculty Orientation, we both came to CofC last summer). I asked what kind of research they will be doing, it seems that they'll study a lot in between math and computer science, general topics are text mining, information retrieval, esp. Web information retrieval (to be more specific, Fiedler vector, Spectral graph partitioning, PageRank — mathematics of, vector space model, latent semantic indexing). We chatted and after much preparation, this is the presentation that I came up with. I also put together a resource page for the group.

Here is the presentation (http://www.cofc.edu/~caod/present4amy.ppt), you should be able to download to your PC or open it in a browser. Here is the resource page (http://www.cofc.edu/~caod/resources_guide4amy.html).

I learned (or reinforced) quite a few things during the preparation for this presentation, I hope you too :-).

the afternoon preconference workshop that I attended, “Creating Online Tutorials Wednesday, 22 March 2006 2:29 am

in Less Than 30 Minutes?” by Greg Notess, the guy of “Search Engine Showdown“.

Is it possible to create well-planned library tutorials (with audios) in 30 minutes? I guess you have to ask Greg yourself. To me, for quick and dirty ones, it’s possible … but well-planned, well-executed library tutorials, I don’t think so ūüė¶

A new term (at least to me), screencast/screencasting … check out Jon Udell’s Screencasting Bookmarks (http://del.icio.us/judell/Screencasting)

Greg indicated that there are commercial and free software out there for screen capture and voice recording, the best options are still those commercial ones (Camtasia Studio, Macromedia Captivate, etc.). (This kind of echoes with my opinion, in an email sent out to my ref folks at CofC quite a while ago, I stressed that we should invest some money in some tutorial software that’s popular and suit our needs, based on my former experiences with Captivate, Viewlet, and some reviews of this type of software).
He gave quite a few examples of tutorials created using each software that he mentioned in the workshop.

Interestingly enough, he seems to like Camtasia a lot, while I remember in one of the review article that I forwarded to my colleagues in an email quite a while ago, they seem to favor Captivate over Camtasia. (I have to dig that review out).

A free software “Wink” (www.debugmode.com/wink) is worth to check out, even though it currently can record only screen actions, no sound, yet (but savvy tech folks may want to combine with Audacity or other audio recording tool/software).

For more updates and software options, watch this wikipedia page (http://en.wikipedia.org/wiki/Screencast).

He gave a lot screencasting planning tips, recording tips (for audio, video, and error handling).

For usability and planning, he mentioned the TUSCWOG (Tutorial Using Screen Capture Working Group).

Here are a few sites to watch for screencasting news:

This is for the students in Prof. Diamond’s Math 495 (Capstone in Mathematics: Explorations in One-Dimensional Dynamical Systems) class.

In case you forget what databases¬†to¬†use to search for articles¬†for your specific applied dynamic system, here’s the page that I¬†created that links to individual database that you may find useful (some of them we’ll go over in the class).
