Stoodle is a web application which allows you, without any download or registration, to create a quick classroom space. By sharing the URL of the classroom you can invite other participants. You can use microphone or text based chat, and upload files (images) to discuss.
It is a somewhat crude platform compared to Elluminate or other classroom spaces, but it is so easy to set up, it is great for enabling student group-work sessions online, or conducting quick seminars! What I like about it is that it so quick to launch, and the interface is clean and straight to the point.
You can only upload image files to share on the “whiteboard”, but you can add text and are able to add extra pages. This allows you, in effect to build an impromptu slide show, You can also record video.
The site itself presents as a tool for both students and teachers to use, and this, to my mind, is one of its most exciting aspects.
All in all it looks like a powerful and promising educational tool. And, best of all, it is free to use! You can’t argue with free!
