Technology in the Classroom

I'm teaching 8th grade Math at FBLG for the past 13 years and I was probably one of the first teachers who introduced powerpoint in the classroom. At first the kids were very attentive, but I found out that even visual kids have certain saturation points, so I will always make it a point to show powerpoint lessons only for about five minutes, followed by discussions, then another five minutes of ppt, then discussions. The only thing that really gets in the way? The lighting in the classroom- we only have one switch and everytime I have to use ppt, I have to turn off the light and that's when trouble always happen- in the dark. Preparation is another thing. It takes hours to prepare a lesson in ppt. I tried other online lessons, but our internet service doesn't allow for a smooth operation, just like what we're experiencing here at UOG. If GDOE wants technology in the classroom, then they should be able to provide us with a better, faster internet service and electronic equipments that can cope with all the technological advancements teachers are supposed to acquire and learn.
