Chalk boards were at first just small squares of slate, framed
with wood to keep them from breaking, and marked on with other shards of slate.
In the early 19th century America started using chalkboards because anything
else was too expensive. The first chalk board to actually be on the wall was
invented by a geography teacher in Scotland who decided to get the slates off
the student’s laps and up onto the wall. The earliest record in America shows
instructors using them in academic military schools, such as WestPoint, in
1801. (Wise GEEK) Teachers didn’t have to spend as long as time writing down
individual problems and lessons could be taught on a single student’s slate,
but could speak to an entire class where everyone had the benefit of seeing the
board. The chalk board became a little more modernized by it having a steel
sheet enameled with porcelain. Also some pieces of slate were replaced by
chalk. And the rag erasers they had been using were no more and they started
using block of felt that could erase chalk marks without creating as much
airborne dust. But later in the 1990’s, concern over student’s allergies and
other health risks created by chalk dust prompted the replacement of the chalk
boards with white boards.
The History of the Smart Board is all thanks to 2 people and
their brilliant company. In 1986 David Martin and Nancy Knowlton were driving
through upstate New York when David had described an idea he’d been working on
to Nancy. A year later, SMART was founded. The company originally was the
Canadian distributor for a United States Projector company. The product David
had first been talking about was the SMART Board interactive whiteboard. It was
able to provide touch screen control of computer apps and the ability to write
over standard Microsoft Windows applications. It’s connected to an LCD panel
and a computer, which brought interactive whiteboards to life and put them in
classrooms, meeting rooms, boardrooms, etc… Back when they were first being
invented no one knew about interactive whiteboards. (Smart Technologies) It
took no effort to inform people about the products and its’ benefits. Teachers
who needed to give lectures at a distance were the first to “jump on” these
products. Although, the early operating systems were often unstable, slow and
offered few to no graphics capabilities. But they were able to progress through
and over time educators around the world came to appreciate the new ways that
they could teach by using the SMART board. At first David and Nancy were unsure
on how their product would be able to work and develop. Luckily they made an
intelligent move in 1992 as they formed an alliance with the Intel Corporation,
which resulted in joined product development. With an alliance and many
investments enabled SMART’s hardware and software to develop into something
incredible. The combined forces were able to come up with and interactive
whiteboard that you are able to touch and do a lot more in which we call a Smart
Board.
