Obsolete & Emerging Technologies: Overhead Projectors & Interactive Whiteboards

Heather Page

Obsolete Technology: Overhead ProjectorDevice that allows users to project slides or transparencies onto a board or screenTo edit any of the information that was on the transparency the teacher had to use special pens that were made for use on overhead transparenciesInability to support the features that more modern technology users requireDo not allow for much student interaction with a lesson nor do they offer the ability to offer multimedia experiences within a lessonTeachers are required to stay with the device during teaching; therefore, reducing teacher interaction with students

Emerging Technology: Interactive WhiteboardA large interactive board that is hung from the wall and attached to a computer and projectorIncreased students ability to interact with a lesson because the students can manipulate information that is on the screenAllows teachers to move around the room as they teach which increases the teachers ability to interact with the studentsAllows the teacher to incorporate more effective multimedia instructional experiencesRequires less mess due to not having to use specialty ink pens or transparencies

Decision Maker Interviews Tammy Allison: Greenwood District 52 Technology Specialist

Interview Questions:

In your opinion, what factors do you believe contribute to a schools decision on what emerging technology they are going to integrate into the school?

In your opinion, what factors do believe contributed to the schools reasoning on integrating the overhead projector?

In your opinion, what factors do believe contributed to the schools reasoning on integrating Interactive Whiteboards?

What new technology do you believe would be integrated in the school when the Interactive Whiteboards become obsolete?

End User Interview 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?

Science FictionScience 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.

Disruptive TechnologiesA 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.

Increasing ReturnsIncreasing 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.

Red QueensRed 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.

Future of Emerging TechnologyI 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 be 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 use 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.

Holographic Technology Tetrad

SummaryThere 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.
