Interactive white boards are used slightly differently depending on the subject of the class. Mathematics instructors are sometimes the first to line up for the boards as they can project graphs, equations, and other visual material on the board. Using the pens, the teacher and the students can draw on the graph. In the language arts, teachers can project a paper and edit using the pens. With animated programs, students and teachers can use the board as a simulator, for example, an interactive animation of an aircraft control panel.
Interactive whiteboards also find use outside the classroom in presentations and office settings. For a committee meeting of faculty, having an interactive white board in the room, as opposed to a traditional white board or chalk board, can provide more visual information to the meeting. Additionally, notes taken on an interactive white board can be saved on a computer, usually as a PDF. Some boards can also recognize handwriting and turn it into typed text. This way, the committee can take notes on the boards and save them for later.
Interactive white boards usually come with special software designed to enhance the board itself. While the boards work with other programs, such as presentation software or word-processing software, the specific program allows for more interactivity. For example, Smart Technologies' uses a program called Notebook. Notebook works like a combination of presentation software, a traditional white board, and an animation program. Teachers can construct their slides before class, then use the Smart Board for an interactive and dynamic lesson in the classroom.
Interactive white boards do have a few limitations. First, they rely on a projected image from a computer. The projector can be behind the board, but it is most commonly in front. Since teachers will stand between the board and the projector, they will cast a shadow on the board. This can make using the board more difficult and students may have a hard time seeing the lesson. Secondly, a mounted projector on the ceiling of the room is usually best, although the boards can work with a projector on a cart or table. If the projector moves, the board must be realigned. This is a simple process and only takes a minute. Third, some boards must be connected to the computer by a USB cable, although wireless technology is also available. Overall, however, the limitations are relatively minor compared to the educational value of the boards.
