An interactive or digital whiteboard is........

A interactive or digital whiteboard is like a normal whiteboard but digital and is better. A computer connected to a projector an it focuses to a didactic and digital screen.
Then you installed one program and you can explain and have class correct the exercises, but there are times that begin to roll and to make the things the other way around. it is used with a species of pen, that you handle the mouse and you put notes etc…

Its positive sides are:

there are more things positives for example: that you didn't have to you the traditional blackboard. the works are better because we aren't say pass pas, you take the pen and when you love raisins. when they explain much more we are concentrated instead of watching the spiderwebs, there look better that the normal blackboard.

We have one in ESO1 and I think .........

for my the PDI have positives things and negative things. To my I like but she was not as much as she hoped I think that it would not give so many failures as gives sometimes. is a important and funny invented.
