History of Technology in Higher Education
We are living in the time of the information boom. Never before has information been so abundant and easy to find. To many students it seems like a hassle to search for information on a computer. Could you imagine finding all of your information by flipping pages of books, magazines, and news papers in a library? “Technology is treated as a tool to help accomplish a complex task rather than a subject of study for its own sake.

The Magic Lantern The first technological tools use in the classroom was the Magic Lantern in 1870. The magic lantern projected images that were printed on glass plates. The first college

This is the cousin of the motion picture projector. The filmstrip projector was used to show educational films in classrooms before videocassette tapes, DVD’s and MP3s. Teachers could pause filmstrip projectors for class discussions by turning a knob. Thomas Edison predicted that with the advent of projected images" books will soon be obsolete in schools; scholars will soon be instructed through the eye" (Vision of Learning: A History of Classroom Projectors 2013). A filmstrip is a spooled roll of 35 mm positive film with approximately thirty to fifty images arranged in sequential order. Like 16 mm film, a filmstrip was inserted vertically down in front of the projector aperture, rather than horizontally as in a slide projector. Therefore, the frame size is smaller than normal 35 mm film. Two image frames of a filmstrip take up the same amount of space as a single 35mm frame, including its guard band, so that a 25 exposure 35mm film can contain fifty filmstrip …show more content…
The first models were originally used by the police for criminal profiles and in the United States Military for training and lectures. The body of the overhead projector is a large box containing a bright lamp and fan which functions to cool the device. On the top of the box is a clear lens platform that light passes through in order to reach the lenses above the box. Hovering over the fan and box is a long neck with one or two mirror lenses. These lenses catch the light coming from the bottom of the device and project it toward a board or blank canvas resembling a flat map. Many recent models provide a doughnut size plastic wheel for adjusting the lenses of the projector for the preference of the user. The overhead projector was a huge success in education. Notes and lectures could be prepared before the

    There are several different ways to deliver a presentation. You can use a slideshow using software such as Microsoft PowerPoint. This allows you to display text, videos, pictures/photos, music etc. Generally a slide will consist of very short bullet points or minimal information so the audience can keep in mind what is being discussed while the presenter gives more information. Presentations can be delivered verbally as a speech, though these tend not to keep the audience’s attention all of the time especially if it is a long speech. Using a projector is another way of delivering a project. It in essence uses a speech type presentation but allows things to be shown to the audience via the projector to keep interest and attention. This method is used a lot in classrooms and during lectures. Flip charts or white boards can also be used as a means of delivering a presentation particularly during interactive sessions where feedback is required from an audience such as while brainstorming or doing a consultation.…

    As the days go by, things change. For now, technology is slowly replacing those labored hands that has controlled th8ings for many years. In the two essays, "From Learning as Torture to Learning as Fun" by Don Tapscott and "Makes Learning Fun" by Clifford Stoll, the two authors discuss the use of computers in education. Both authors discuss the positive and negative points that new age generation technology has had on today's society. One author leans toward the good in technology and the other author leans toward the bad in technology. While both essays express many strong points about the use of computers, I am leaning towards Clifford Stoll and agree with him. He clearly gives his thoughts of how technology…

    Overhead projectors are for the use of transparencies. Overhead projectors allow the user to place a transparency (clear plastic sheet with writing or pictures) on a reflective lens and project a much larger image onto a wall or screen (Goodall & Hawks, 2004).

    Compared with traditional textbooks, the iPad and other devices for reading digital books have the prospective to save on textbooks costs in the long term, to provide students with more and better information faster, and – no small matter – to lighten the typical college student’s backpack. Santa Clara University student Christopher Paschal, 19, for instance, esteemed the search function in his economics e-textbook, and said the included video clips offered “An alternative method of learning,” and eliminated “The monotony of endless pages of reading.” But eventually, “I feel that I comprehend material better in regular textbooks, “Paschal says. “Textbook publishers haven’t had a chance to modify things for the iPad. If publishers really get behind the iPad, I can see a day where it’s the only thing I would bring to school.” Even then, some evidence recommends students see a downside to 24/7 interactivity when it comes to formulating for exams or doing homework. During visits last fall to libraries, coffee shops and other campus hangouts to scrutinize how students study, a test-prep company noted that, when it was time to study, cellphones, laptops and Kindles were put away. A 2005 review by researchers at Carleton University in Ottawa, Canada, of 38 studies initiate “Very little support” for the idea that all those links to additional information enhance the reader’s experience. The online environment “Promotes cursory reading, hurried and distracted thinking, and superficial learning, “ argues Nicholas Carr, who raises concerns about the long-term implications in The Shallows: What the internet Is Doing to Our Brain, which was published in June.…

    The magic lantern is the predecessor of the modern day projector. It consisted of a translucent oil painting and a simple lamp. When put together in a darkened room, the image would appear larger on a flat surface. Athanasius Kircher spoke about this originating from China in the 16th century but it was developed in the late 1650’s by Christian Huygens. Some slides for the lanterns contained parts that could be mechanically actuated to present limited movement on the screen.…
