Disruptive+Technology

Teachers have been using chalk boards and white boards for a long time to provide instruction. When the overhead projector was introduced to the classroom teachers now could use them to project copies of papers that they may have wanted to show the class, but overall most classroom teachers still used the white board for everyday instruction. White boards are easy to clean and dry erase markers come in various colors so why keep having to wipe off an overhead projector all the time. However, when the Activboard came into play teachers could now write on a board in not only various colors, but also could adjust the width of the mark they make, use thousands of resources such as shapes, grid backgrounds, and you can write over anything that is on a computer screen. Since the Activboard is a vast improvement over the chalk/white board most teachers with Activboards do not even use their chalk/white boards anymore. Therefore, overhead projectors were not a disruptive technology for chalk/white boards since instructors still used them but Activboards are a disruptive technology for both the white board and overhead projector because the majority of teachers with an Activboard will no longer need to use the overhead projector anymore.
