Blackboards are communication devices used in offices and classrooms. The original chalkboard was a white dry-erase board. Whiteboards come in different types, including interactive computer touch screens and online interactive spaces. They can be used to display information, project media, and capture contributions from multiple participants.
The term blackboard indicates various devices used for communication in offices and classrooms. The original chalkboard was literally a white dry-erase board. It got its name by analogy with blackboards called chalkboards. Like them, the whiteboard is a device that you can write on and erase, so it’s useful for many of the same situations as a whiteboard or flipchart, creating a space for multiple people to see, reference, or interact with.
Dry-erase markers made for the original type of whiteboard include bolder colors than those found in chalk and, of course, can be used without creating chalk dust. One problem that arises for some people with dry erase markers is the smell, and you have to be careful not to use markers that aren’t made specifically for the surface because they don’t erase easily. This type of chalkboard comes in a variety of sizes.
Another type of whiteboard is an interactive computer touch screen that allows you to operate a computer by touching the whiteboard. Some of these whiteboards allow interactive screen capture, which means that with a simple operation you can copy the material created on the whiteboard to your computer. Other features of a computer-enabled whiteboard include interactive annotation of the computer’s projected image and interactive annotation to fill in a projected template, both of which can be saved via screen capture.
A third type of whiteboard is an online interactive space available for entering text, drawings, and so on. People in different locations can all access the same whiteboard space and create a mutual composition, plan, project or drawing that is visible to all users in real time.
You can use any type of whiteboard:
demonstrate or display information previously prepared for multiple people to view;
as a surface onto which to project non-interactive media such as slides, movies, power point presentations, or a real-time display of a computer screen to entertain, educate, or inform; And
to capture the simultaneous or sequential contributions of multiple participants in a forum, recorded by the participants themselves or by a designated scribe.
