About the Author & Resources
About the Author I, Emma Tatum, am a teacher who loves to use technology in my lessons. Some people are still skeptical when it comes to incorporating technology into the classroom on a regular basis; I understand this skepticism because I used to be one of those people but I remained openminded. 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. ________________________________________
