Blog Post on Emerging Technologies Tetrad
There is an expectation for leaders
in educational technology to be aware of new emerging technologies. Thornburg
(2013e) examines Marshall McLuhan’s Laws of Media, which seek to answer
questions that form a tetrad of the four laws of media. The first law extends
or amplifies a technology to do something new (Laureate Education, 2014f;
Thornburg, 2013e). The second law demonstrates obsolescence, where a new
technology will drive and supersede an old technology (Laureate Education,
2014f; Thornburg, 2013e). The third law is retrieval which rekindles something
from the past (Laureate Education, 2014f; Thornburg, 2013e). The fourth law is
reversal to help set the stage for a technology replacement (Laureate
Education, 2014f; Thornburg, 2013e).
Holography is an emerging technology
which enables users to make three-dimensional images. Holograms use a laser,
diffraction, light intensity recording and illumination. The image appears three-dimensional
as the viewing system changes the position and orientation of the image. Walsh
(2012, November) projects holograms as being the next step forward towards the
evolution of technology. There is a projection that the use of holographic
telepresence will bring digital participants and remote location to classrooms
with the use of three-dimensional technology.
synchronously to students anywhere in the country. Holograms will allow educators to bring their content to life. Learners can experience sites and sounds during instruction that can enhance their classroom learning (Walsh, 2012 November).

Emerging Technology – Holograms
Enhances –
Allows experts and facilitators the ability to illustrate processes live, and in person
Allows instructors to deliver lectures to multiple classrooms, anywhere, simultaneously
Allows experts to deliver a new dimension to instructional content.
Obsoletes –
Need to use overhead projectors, whiteboards, chalkboards, filming projectors, digital and video tape players, and possibly interactive whiteboards
Retrieves/Rekindles –
Ability for teachers to promote teacher to student discourse
Ability to rekindle pedagogical practices that promote cognitive learning
Ability for teachers to facilitate rich classroom discussions and clarification
Reverses –
Into three-dimensional simulations to for teaching physical world concepts to students
As an emerging technology, holograms allow experts such as facilitators to model and demonstrate a strategy without having to be in a classroom. The instructors deliver instruction
Holograms obsolete the need for overhead projectors, whiteboards, chalkboards, filming projectors, digital and video tape players. Holograms may eventually replace interactive whiteboards. A three-dimensional presence can enhance the learner’s instructional experience.
Holograms retrieve the ability to promote learner engagement. Teachers can use the three-dimensional models to promote teacher to student discourse. Modeling the features from three-dimensional objects allows teachers to rekindle pedagogical practices that promote cognitive learning. Holograms will allow students to demonstrate and also model what they know. The features allow teachers to facilitate rich classroom discussions and clarification.
Holograms may reverse into three-dimensional simulations. Two-dimensional computer simulations already exist to support students in focusing on a particular task. Imagine being able to provide holographic simulations where students can interact with three-dimensional objects that models a real world environment.
In the medical field holography is providing the world with the first
3D holographic display and interface system, initially for medical imaging
applications.
