DESCRIPTION
In a nutshell screen capture is the art of developing educational materials by capturing a video of what is happening on a computer screen. This simple process can allow rapid creation of rich-media instructional aides. In this talk I will present some experiences of mine and of my colleagues in developing these resources for students of Oscail in Dublin City University who are studying a Bsc. in Information Technology by distance education. I will look at some tips I wrote two years ago on this topic and examine their continued relevance. The take-home message of this talk will be “publish or perish”, an exhortation to the educator to focus not on fancy production or editing of screen captures but rather on a process that involves a minimum of time and technical effort to create videos and get them to students. To finish I will give an overview of how we are using Camtasia Studio with Google Video as part of DCU’s roll out of Google Apps for Education and demonstrate some interesting aspects of this elearning platform.

Screen Capture/Casting = computer screen + audio• capture v casting• Live v Synchronous• Off-with-their-heads: computer screen
only:– PowerPoint (see death-by)– Software: Program walkthroughs– Website/VLE training– Whiteboard:
• pen input e.g. Mathematics
– Anything else…

Examples: Webpage walkthrough
Examples: Programming
Examples: Maths with pen input
Examples: With Powerpoint
From JK to D & T type flip-flops.avi
Didactic medium
• Chalk and Talk• Proposed Solutions:
– Chunking (Gobet, 2005)– Video length (Bandwidth and Boredom)– Adding interactivity
• Quizzes, • “click here if you are awake/alive”

9 tips for Camtasia
1. Don’t be seduced by post-production..
Teaching/Instruction
Capture
Produce/EditDeploy
More Tips
2. Don’t strive for perfection (publish or perish)
3. Record at a low resolution
4. Avoid pan and zoom
5. Don’t aim for ipod/mobile phone
More Tips
6. Batch publish
7. The ten minute rule
8. Publish to Flash.9. Don’t bother with the freebies
Software
• Synchronous/Live classroom systems with “archive” feature
• Jing – free but limited• Adobe Captivate• Camtasia (FTW)• Screenr (web-based)• Linux: recordmydesktop
Hardware
• All you need:– Computer– Wired headset or built-in laptop mic
• All you can eat:– Tablet PC (NOT an iPad!)– Usb pen (?)– Bluetooth or DECTS headset– Mobile projector (pico projector)
Camtasia• Inexpensive• Does the basics well
LOOK AWAY NOW: HERE COMES THE TECHNICAL BIT!Camasia file-types: Camproj and Camrec
Camrec really just a wrapper for AVI Tip: Right-click camrec file >> click extract TA-DA! You have an AVIWhy is that important? Because Google Video can render the video for you
Google Apps for Education
Video in a Web 2.0 World• Google Video (in Google Apps for Education)• Tagging
– Allows better organization of content – Allows for custom menus– But no RSS yet :-(
• Could allow automated updated content alerts for students
• More learner control– Speed of playback– Download content– Comment , Tag and Rate
Conclusions
• Don’t post-produce & don’t worry about you presentation style: Just be yourself
• Camrec >> AVI >> Google Video for Education >> MP4
• Tags to organise video • Google Apps + Moodle + Camtasia =
eLearning ecosystem
