I did a college level research paper on technology use in the classroom a couple years ago. Every source I found concluded technology expenditures did not improve core subject learning. The only benefit was exposure to equipment students would later need in the workforce, but that often came at the expense of measured progress on standardized tests. The surprising conclusion I came to was this isn't just an American thing. According to the UN, underdeveloped nations don't see the expected gains by putting laptops in the hands of their students. Some even do worse because the computers become a distraction. Essentially, they quickly learn to look up cat videos on the internet.
