This use, however, has generally been limited to “business” classes that focus specifically on teaching students how to type
  • Overhead Projector

    Overhead Projector
    In the 1930’s the overhead projector was widely used by the U. S. Military to train forces during World War II and eventually the device spread to schools.
  • Videotape

    videotapes were introduced in 1951 after radio broadcasting. It was expensive and only for wealt people around the world, but it was a great step to learn lessons.
  • Teaching Machine

    Teaching Machine
    The premise behind teaching machines was that objectives must be defined in advance and the extent to which these objectives are achieved must be measured. Students operated the machines themselves and followed instructions on a screen similar to a television. Typically, individual student cubicles were set up to block the noise made by the machines. This format minimized the amount of interaction among students and between students and the teacher.
  • Television

    Some programs are primarily aimed at entertainment, but may contain an incidental amount of educational content. Educational content may be inherent to the design of the show, such as with medical dramas where the plot invariably explores anatomical and biological issues.
  • Computers

    . Computers were first used in education in the 1960s in a way that was intended to individualize instruction. This method became known as computer assisted instruction (CAI).CAI was intended to teach students a specific content area. Initially, the only difference between CAI and teaching machines was the type of technology used to deliver the material. Drill and practice techniques were common.
  • Video Conferencing

    Video Conferencing
    video conferencing was first introduced and packaged as a commercial solution at the World’s Fair in New York. The technology introduced was called the Picturephone from AT&T. Participants were able to sit down and communicate “via video” with the person on the other end for 10 minutes at a time to experience the first video telephone device designed for the masses. Unfortunately, this particular machine was ridiculously expensive, clunky and difficult to set up, so it didn’t exactly take off.
  • The Internet

    The Internet
    The Internet allows learning to take place on a many-to-many rather than one-to-many basis, thereby supporting socio-constructivist modes of learning and cognitive development that are profoundly social and cultural in nature. Many educators would consider learners to benefit from the socially rich environments that the Internet can support.
  • Online Courses
