Multimedia Presentation Obsolete and Emerging Technology
- 2. Obsolete Technology: Overhead Projector ▪ Device that allows users to project slides or transparencies onto a board, screen, or wallet point here ▪ To edit any of the information that was on the transparency the teacher had to use special pens that were made for use on overhead transparencies ▪ Inability to support the features that more modern technology users require ▪ Do not allow for much student interaction with a lesson nor do they offer the ability to offer multimedia experiences within a lesson ▪ Teachers are required to stay with the device during teaching; therefore, reducing teacher interaction with students
- 3. Emerging Technology: Interactive Whiteboard ▪ A large interactive board that is hung from the wall and attached to a computer and projector ▪ Increased student’s ability to interact with a lesson because the students can manipulate information that is on the screen ▪ Allows teachers to move around the room as they teach which increases the teacher’s ability to interact with the students ▪ Allows the teacher to incorporate more effective multimedia instructional experiences ▪ Requires less mess due to not having to use specialty ink pins or transparencies
- 4. Overhead Projector Tetrad Enhances * Allows larger groups to view images and documents. * Allows notes to be used over without rewriting them. * Allows teachers to display information and images to a class quickly. * Allows users to project slides or transparencies onto a board, screen, or wall. * Allows users to accommodate for different learning styles and multiple intelligences Reversal * Systems that will project from other devices. * Projection devices that will not require special pens or sheets Obsoletes * Reduces the amount of paper used for photocopies * Chalkboard * Slide Projectors Retrieval * Movies and Filmstrips * Opaque Projectors
- 5. Interactive Whiteboard Tetrad Enhances * Increased student’s ability to interact with a lesson because the students can manipulate information that is on the screen * Allows teachers to move around the room as they teach which increases the teacher’s ability to interact with the students * provide the teacher to incorporate more effective multimedia instructional experiences Obsoletes * Overhead Projector * DocumentCamera Retrieval *Whiteboards * Flipcharts *Video/media Systems Reversal * Holographic Images * 3D Images
- 6. Decision Maker Interviews Tammy Allison: Greenwood District 52 Technology Specialist Interview Questions: In your opinion, what factors do you believe contribute to a school’s decision on what emerging technology they are going to integrate into the school? In your opinion, what factors do believe contributed to the school’s reasoning on integrating the overhead projector? In your opinion, what factors do believe contributed to the school’s reasoning on integrating Interactive Whiteboards? What new technology do you believe would be integrated in the school when the Interactive Whiteboards become obsolete?
- 7. Teacher Interviews Tyler Larkins: Edgewood Middle School Pre-Algebra/Algebra 1 Teacher Interview Questions: Did you ever use an overhead projector? Did you ever use an Interactive Whiteboard? In your opinion, how does an overhead projectors differ from interactive whiteboards? Would you prefer to use an overhead projector or an interactive whiteboards? Why? In your opinion, why do you think we see less use of overhead projectors?
- 8. Science Fiction Science fiction provides a vehicle that allows innovators to imagine and grow. Dr. Thornburg (Laureate Education, 2014i) describes science fiction as the stories that trigger the imaginations of investors. Overhead Projector This type of technology was never seen in movies before it was invented. Interactive Whiteboard Science fiction movies were filled with touch screen devices before the interactive whiteboard was invented. The Sci-fi movie Minority Report (2002), introduced touchscreen devices before they emerged.
- 9. Disruptive Technologies A disruptive technology is a technology that displaces another technology. Thornburg (Laureate Education, 2014a) defines a disruptive technology as new technology with the same functionality of an existing technology. The new technology functions more efficiently, and will obsolete the previous technology. Interactive whiteboards changed the way teachers taught in schools. They replaced the overhead projectors, that had limited capability. This new and exciting equipment changed the ways that students were presented information.
- 10. Increasing Returns Increasing returns is when two technologies emerge at around the same time and one drives the other to extinction. Overhead Projector There was not another technology tool that emerged at the same time of the overhead projector. Interactive Whiteboard Interactive whiteboards have consistently driven out the use of overhead projectors to the point that all they do is gather dust on shelves in the back of media center closets.
- 11. Red Queens Red queens is when there is a competition between technologies and one is left behind. Overhead Projector When the overhead projector emerged into classrooms they were in competition with slide projectors. Interactive Whiteboard There is presently competition between the interactive whiteboard and the document camera.
- 12. Future of Emerging Technology I believe that there will soon be a projector that will allow for 3D and/or holographic images to be projected into the classroom. According to Kelly Walsh (2012), holographic technology is the next step in this evolution – the use of holographic telepresence to bring digital participants and remote location into the class in 3D. This type of technology is still many years in our future; therefore, the interactive whiteboard will around for at least 5-10 more years. Holograms will allow teachers to model and demonstrate a strategy without having to be in a classroom. Holograms will allow educators to bring their content to life. Holograms will make the for overhead projectors, whiteboards, chalkboards, filming projectors, digital and video tape players obsolete. Holograms may eventually replace interactive whiteboards. A three-dimensional presence can enhance the learner instructional experience.
- 13. Holographic Technology Enhances Allows experts and facilitators the ability to illustrate processes live, and in person. Allows instructors to deliver lectures to multiple classrooms, any where, simultaneously. Allows experts to deliver a new dimension to instructional content. Rekindle Ability to rekindle pedagogical practices that promote cognitive Obsoletes Need to use overhead projectors, whiteboards, chalkboards, filming projectors, digital and video tape players, and possibly interactive whiteboards Reversal Ability for teachers to promote teacher to student discourse Holographic Technology Tetrad
- 14. Summary There is an expectation for leaders in educational technology to be aware of emerging technologies. Creating a tetrad shows how new technologies emerge and how other technologies become obsolete. Dr. Thornburg (Laureate Education, 2014f) points out that creating a tetrad supports practitioners in being aware of how new technologies incorporate creative processes into everyday life. New technologies support learners and facilitates learning. As a futurist, it is important to be aware, explain, and be able to demonstrate the significance of using an emerging technology.
