'Palpable excitement' of 3D school lessons revealed
Following Texas Instruments' BETT demonstration of its single-beam 3D projector system designed especially for schools, more details have emerged of the US experiment that tested the effects of 3D learning and uncovered jumps of up to 35 per cent in students' grades.
Thousands of students in Illinois experienced lessons based on 3D simulations - including a science class featuring a 3D human ear that was "disassembled" by the teacher - thanks to grant funding.
"The first comment from the teachers was that there wasn't one discipline issue - which amazed them," says Tracey Masamoto, director for 3D content at the firm which carried out the tests.
A "palpable" excitement was brought to the classroom by the 3D lessons, she adds: "[The children are] all paying attention, not talking about their lunches or after-school activities. They're engaged and reaching into the air to grab objects."
Many more students can be reached with 3D lessons with different - visual - learning styles, she concludes.
Texas Instruments' projector system, which works by beaming left-eye and right-eye images alternately from the same DLP chip, is to be used in upcoming devices from manufacturers including Optoma, Vivitek, Acer, BenQ, NEC, Sharp and Vivitek.
