3D Projection Technology in the Classroom

The BETT show was the perfect occasion for makers to show new3Dprojection-0112 3D DLP models combining cost effective, lamp-free illumination with 3D teaching.

Texas Instruments DLP announced at BETT Show 2012 the availability of all new, lamp-free projection solutions from BenQ and Optoma, each powered by DLP technology. With lamp-free illumination versus traditional bulbs, the BenQ LW61ST (WXGA)/LX60ST (XGA) and Optoma ZW210ST (WXGA)/ZX210ST (XGA) projectors can each offer approximately 2000 lumens to light up today’s classrooms, while increasing the lifespan of the projectors and reducing long-term maintenance costs.

These new models join exciting solid state illumination projector models from Casio, incorporating other in-demand features, such as 3D-readiness, connectivity and interactivity to best fit current as well as future teaching demands.

In addition to being lamp-free, the new BenQ and Optoma are also part of the group of DLP projectors that are 3D-ready. Known for its use in today’s movie theaters, video games and elsewhere, now 3D has been demonstrated to have a positive impact on students’ potential at school.

Recently Professor Anne Bamford, director of the International Research Agency, released findings from the LiFE research project, which aimed to measure the value and impact of 3D experiences on student learning and achievement and determine the most effective types of 3D experiences.

The study was undertaken between Oct. 2010 and May 2011 across seven European countries and revealed that students’ comprehension, information retention and overall behavior all improved with the addition of 3D projection in the teaching/learning environment.

Measured by comparing the pre- and post-test results of 2D and 3D sample groups, the study found that:

• On average 86 percent of students improved from the pre-test to the post-test in the 3D classes, compared to 52 percent who improved in the 2D classes.
• Individuals improved test scores by an average of 17 percent in the 3D classes, compared to an 8 percent improvement in the 2D classes between pre-test and post-test.
• 92 percent of students on average were attentive during 3D lessons, while only 46 percent were actively paying attention during non-3D lessons.

Whatever criticism 3D faces from cinema and residential markets, this research gives 3D a passing grade in education markets.
