More often now than ever before teachers are using to tecnology as teaching aids, and teachin ‘crutches’ so to speak. In just about every classroom you will certainly find a computer, or a bunch of computers for students and teachers to utilize for various activities. You will also find teachers using programs such as Microsoft Power Point in order to help them teach and give lecture notes. In a classroom, if it is a mathematics course, you will find students using TI-84 graphing calculators instead of doing the mathematical operations by hand. You will also find television sets and dvd players within a classroom to use for teaching various lesson plans. You will also find music players and projectors within many classrooms as well.
