What is screencasting?
Screencasting technology allows you to record what is happening on your computer screen with accompanying audio commentary and then share it with others. It enables remote collaboration and learning and provides an effective medium for educating users in the best use of databases and online resources.
It is a handy and useful tool for students, teachers and developers of software and web resources. Screencasting is especially useful in learning environments where it can be used to make live recordings of presentations or training sessions, to comment verbally on projects and assignments, to remotely show students how to use software or search a database, or for collaboration on projects. Developers can use screencasting to highlight features in new products or to give a tour of a website or resource.
These tools can also be used socially for things like sharing narrated slide shows with friends.
