If you attended school between 1900-1920, there would sure be a different feel—you’d likely be in a one-room schoolhouse. In 1923, the learning environment became more sophisticated as classrooms began incorporating radios into penmanship, accounting history, and arithmetic lessons. A decade later, overhead projectors—initially used for US military training—quickly spread to schools. By 1933, 52 percent of schools were using silent films and three percent were using films with sound. A major breakthrough took place in 1939 when the first TV appeared in a classroom in LA.

Fast forward to the late 1960s and early 1970s. In 1967, Texas Instruments developed the handheld calculator. Five years later, scantrons were used to automatically grade multiple choice tests. The year after, the Minnesota Educational Consortium was founded, and the organization popularized such software as Oregon Trail (1974) and Lemonade Stand (1973). Did you grow up playing Oregon Trail in school? A major breakthrough took place in 1984 when Apple Macintosh computer was introduced.

Technology in schools is extremely advanced these days. In 2012, 1.5 million iPads were used in schools. Right now, 90 percent of students under the age of 18 have access to mobile technology.
