Evolutionary+Technologies

Evolutionary technology occurs when a demand that has already been met can become improved upon. The original technology of the chalkboard had a great impact on education because a teacher could instruct several students at one time. The chalkboard was improved upon by introducing white boards to classrooms with dry erase markers. However, if a teacher wanted to really show their students how to answer something on a worksheet there was no way to show everyone at once. Teachers had to walk around the room showing each students how to do their work. This need was met by the introduction of the overhead projector. The overhead projector was an evolutionary technology that was extreamly useful to teachers because they could now copy a worksheet onto a transparency and project it on the wall for their class to see. Textbook companies still include transparencies for teachers to use today because of the resoursefulness of them. As time moved forward just as teachers had a need to show worksheets to the class they began to have a desire to show PowerPoint presentations, videos, and a need to have more interactive lessons. As great as the overhead projector was when it was introduced there is always room for improvement and that improvement came in the form of the Activboard. The Activboard made the overhead projector virtually obsolete (in fact I ridded myself of mine the minute I received my Activboard). This is actually a good thing though because the Activboard allows users to do so much more than just write on a board or project worksheets. It allows users to use interactive flipcharts, games, watch videos, and PowerPoint presentations and therefore allows more student interaction with technology and an opportunity to further learning. However, my activboard has a mounted projector on it so it is an evolution of the overhead projector.
