Scribblar: A Free Online Multi-user Whiteboard

If you are online training or tutoring, and you need an interactive whiteboard, you may want to explore Scribblar. Scribblar is a free online collaborative whiteboard designed for multi-user use.

In Scribblar, users in a single room can use the same whiteboard to draw and react on objects on the screen. A snapshot of the whiteboard can be taken for filing and later work. In addition, Scribblar also supports text  and live audio chat.

For math teachers, Scribblar supports Latex and allows embedding of Wolfram Alpha search results.

Free Mathematics Whiteboard Applet

Last January, I posted a link of an electronic whiteboard that teachers can use for classroom presentations.  This time, there is a better applet that you can use for presenting as well as teaching mathematics. This applet was created using Dbook, a Japanese software that enables teachers to create intereactive electronic books. I will post a separate article later about it.

The Mathematics Whiteboard

This applet has the usual pens and eraser tools.  What is more interesting is that it has also mathematical tools such as ruler, compass and straightedge, protractor, and triangles. You can also draw point, line and circle tool. Unfortunately, I can’t find a way to upload it in a free server, since it contains an executable file (most servers won’t allow it), but you can download it here and use it offline.

Dbook is a Flash-based program, so you will need a Flash Player.

Update: If you cannot download the white board applet in the link above, click here to download it from another location.

Free Whiteboard Software

If you are using computers during lectures, or fond of screencasting, you would probably need a software where you could scribble.  You would need a blackboard or a whiteboard software. There are several free software that you could use – you could use PaintBrush or Flash Player.

One of my latest internet dig, however, would also be a good choice. It is called  Classic WhiteBoard. It is available in Windows, Linux and Mac platform. Its screenshot is shown below.

What I love about this software is that it is very easy to use (click here to view screencast tutorial) and it really looks like a whiteboard.  It works very much like PaintBrush.  One of the disadvantages, though, is that it has only four colors.

Update: I have uploaded a better whiteboard software added with math tools such as compass, straightedge, triangle and protractor here.
