This info graphic really displays the change in technology over time as it pertains to teaching. It shows the evolution from older technology (overhead projectors, VCR players, tape recorders, etc.) and newer technology (graphing calculators, smart phones, laptops, etc.). Many schools do not have enough funds to replace all the old technology, so classrooms have a mix between the old and the new. This could be a potential problem because new technology like social media and educational apps have proved very effective as opposed to the outdated technology.
