2. OBJECTIVES
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
3. WHAT IS 3D?
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.
4. 3D IN THE CLASSROOM
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.
5. 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.

7. 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.
8. WHY 3D FOR EDUCATION?
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.
9. 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.
10. 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.
11. THE 3D EDUCATIONAL EFFECT
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%.
12. 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.
13. AOA ENDORSEMENT
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.
14. 4 TIPS FOR USING 3D IN THE CLASSROOM
1. Provide
training.

and
ongoing
faculty
2. Create a 3D-friendly environment.
3. Keep Track of the Equipment.
4. Take the time to manage your 3D content.
15. 3D MATERIALS
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.
17. 3D MATERIALS
3D Printer
Bringing 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
