screen capture all your lectures
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.TRANSCRIPT

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…

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”

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
![Page 18: Screen Capture All Your Lectures](https://reader034.vdocument.in/reader034/viewer/2022051514/54b35ac34a7959be4c8b4681/html5/thumbnails/18.jpg)
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
