Since technologies since hit the market, there has been a continual procession of improved and new products each and every year. While new technologies have fallen off recently, the quality of technology continues to advance. Schools have found that, in their attempt to try and access the most recently technology that technology itself has deeply added to the cost of education. Unfortunately, this isn't necessary because schools do not need the most advanced technology to teach children.
Spending money on technology generally does not improve education as effectively as customized instruction, school choice, and other flexibility. Technology would be better implemented, if market forces were brought to bear tech acquisitions. Meanwhile, it lets instructors off the hook for a while, then the tech does not show vast improvements in scores, and school syst,es are back spending more money.
