Rhymes+of+History

Rhymes of history suggests that the evolution of technology sometimes brings us back to where we started with a need that was already met. For instance, teachers had a need to make demonstrations in front of large groups of individuals and this need was met with a slate board. However, the same need was met again with the overhead projector and again with the Activboard. Overhead projectors emerged because of the growing need to demonstrate to students ideas that were on paper. This is the same need as before only with paper handouts in place it made sense that teachers would want a copy for all to see. Again this need was met with the Activboard because now all students can see what is happening on the computer screen at once. Of course this explains why the overhead projector became obsolete with the growing need to deomonstrate what is happening on the computer screen. With the growing demand of teachers wanting an interactive board to use in front of the class the rhymes of history accuratly describes why the Activboard has emerged and why it has obsoleted the overhead projector.
