Mathtrain.TV: Episode 55 “Our First Student Screencast from 2007”

mathtrain@gmail.com (Eric Marcos) — Sat, 25 Jul 2009 00:56:43 +0000

Here is our first official, student-created mathcast from 2007. It is the early version,which is not edited too much. It is a bit longer than most of our math videos.

However, 6th grader “Bob” (not her real name) created this on the spot, with no script and no rehearsal. It was also her FIRST time ever using Camtasia Studio. Camtasia Studio is the screen recording software we use. I thought we should release this as an episode.

What is a URL? (The iPhone/iPod Version)

I composed the music from putting together numerous generic loops in Garageband.

I need to take a survey soon and find which file type is preferred by you. Here is one specifically for the iPhone and iPod. Let me know if this version is better, or not necessary since the other mp4 files can easily be converted in iTunes. Thanks.

World’s First 3D Mathcast.

I just got a new 3D webcam called, “Minoru 3D Webcam“. I decided to make my first 3D video a mathcast of course. It’s silly and really just a demo to see how the 3D effects look.

I think my students will do a better job with this camera. Stay tuned for future math video lessons in 3D.
