3-DIMENSIONALMATERIALS

At the end of the report, you will be able to:

define what 3D is.

know the benefits/advantages of bringing 3D in the classroom

know the effects of 3D in education

identify some 3D materials used in teaching-learning environment

OBJECTIVES

In the broadest definition of the term, "3D“ (three dimensional) would describe any object that occurs on a three-axis Cartesian coordinate system.

3D is any object that can be represented on a three-axis system.

WHAT IS 3D?

As educators grapple with school reform, many agree that schools must update their practices and technology to better engage students and prepare them for 21st-century careers.

3D IN THE CLASSROOM

Studies have shown that the educational benefits of presenting teaching materials in 3D are promising, generating a significant improvement in comprehension and retention over the more traditional non-3D style of presentation.

3D IN THE CLASSROOM

When deployed strategically, 3D has been shown to not only increase test scores, but also foster an increased understanding of abstract, more difficult to grasp concepts.

3D technology also has been shown to command student’s attention, while enabling them to explore and experience key concepts on a more detailed, personal level.

3D IN THE CLASSROOM

There are neurons in our brains, a specific type of mirror neuron, which encode information according to the viewer’s perceived distance from an object. When objects are perceived to be within our “haptic envelope” that is, the immediate space around us where we feel we can reach out and touch any given object, these neurons are activated, thus engaging more of our neural pathways and resulting in a stronger memory. 

WHY 3D FOR EDUCATION?

If an object can be brought closer to a student, their retention will increase.

3D images bring projected objects within

each viewer’s haptic envelope, resulting in each viewer having the same experience at the same time.

WHY 3D FOR EDUCATION?

An illusion of touch, thereby activating your spatially selective mirror neurons is giving you a richer experience.

The more of our senses engaged in a particular activity, the more neural activity, the more we remember and retain.

WHY 3D FOR EDUCATION?

One such study, completed back in 2000 by the National Research Council of Canada, did a comparison of a standard 2D classroom experience vs. a 3D virtual training session for students engaged in wood harvesting. The findings were amazing.

The students involved in 3D virtual training increased the volume of wood harvested by 23% while reducing mistakes as well vehicle repair and maintenance costs by 26%.

THE 3D EDUCATIONAL EFFECT

Another study tested NASA employees in object recognition.

The 3D virtual training participants had a decrease in errors by 40% and 12% faster recognition than their 2D training counterparts.

THE 3D EDUCATIONAL EFFECT

3D has a powerful effect on students understanding, awareness and retention.

One reason could be that we are engaging mirror neurons by bringing objects and videos within our haptic envelope. Research has shown that students are more attentive and perform better academically when taught with 3D technology. The American Optometric Association has even endorsed educational 3D as both an instructional aid and a diagnostic tool.

3D technology is an easy way to make learning more personal and more productive than ever before.

AOA ENDORSEMENT

1. Provide upfront and ongoing faculty training.

2. Create a 3D-friendly environment. 

3. Keep Track of the Equipment. 

4. Take the time to manage your 3D content. 

4 TIPS FOR USING 3D IN THE CLASSROOM

3D-Enabled DLP Projector

DLP ("Digital Light Processing") is a proprietary technology developed by Texas Instruments. It works quite differently than LCD. Instead of having glass panels through which light is passed, the DLP chip is a reflective surface made up of thousands of tiny mirrors. Each mirror represents a single pixel.

In a DLP projector, light from the projector's lamp is directed onto the surface of the DLP chip. The mirrors wobble back and forth, directing light either into the lens path to turn the pixel on, or away from the lens path to turn it off.

3D MATERIALS

3D Glasses - enable the viewing of objects as three-dimensional.

3D MATERIALS

3D PrinterBringing a 3D printer into a school or classroom needs to be first and foremost about pedagogy and opportunity. As with any other technology, it will do little good to spend valuable budget money on technology that you haven’t got a solid plan to use. Shiny gadgets that sit in the corners of rooms and are not used do little to enhance learning.

When you are deciding to buy a 3D printer for your school or classroom, make sure that you first take pedagogical and learning goals into account. These printers are no different than any other gadget and you must ensure that you have a solid plan in place for their use. After this, there are a number of other factors that you need to think about: budget, supplies, models, suppliers, reliability, time you want to spend on the machine itself, etc. These are all factors to consider. 3D printing is a powerful concept
