About the Author

I, Emma Tatum, am a teacher who loves to use technology in my les-sons. Some people are still skeptical when it comes to incorporating tech-nology into the classroom on a regu-lar basis; I understand this skepti-cism because I used to be one of those people but I remained open-minded. I believe that technology is the direction our world is moving in

and that the education system needs to keep up with the rest of the world.
