Proof-of-concept interface design project from MIT Tangible Media Group demonstrates a system combining the use of a smartphone with a desktop computer - video embedded below:
THAW is a novel interaction system that allows a collocated large display and small handheld devices to seamlessly work together. The smartphone acts both as a physical interface and as an additional graphics layer for near-surface interaction on a computer screen. Our system enables accurate position tracking of a smartphone placed on or over any screen by displaying a 2D color pattern that is captured using the smartphone’s back-facing camera. The proposed technique can be implemented on existing devices without the need for additional hardware.
There’s no such thing as a “normal brain.” In fact, there’s a lot of diversity in how different brains process information — a challenge for educators tasked with teaching a diverse group of learners. Dyslexia is a common variation that affects how kids read, but what’s really going inside the brain of someone affected by it? Kelli Sandman-Hurley’s TED-Ed video explains.
When an excellent principal is hired at a high-poverty school, time for teacher training and collaboration increases, student test scores rise by 5 to 10 points annually, and ineffective teachers begin to leave—yes, even under today’s often overly restrictive tenure policies. When a good principal departs, the progress unwinds and student achievement drops. In short, principals have a unique power to multiply the effects of good teaching and help close achievement gaps.
Everything about Teach for America is being subjected to internal debate, from the length of the five-week training and two-year placements to the very language it uses to describe its mission and impact. What does TFA’s evolution mean for a national school reform movement built upon the organization’s ideals?
Female students, for example, are poorly represented in science, technology, engineering, and math courses offered online, just as they are scarce in STEM classes conducted in physical classrooms. Demographic analyses of the students enrolled in much-hyped “massive open online courses” show the depth of the gender gap. “Circuits and Electronics,” the first MOOC developed by the online consortium of universities known as edX, had a student body that was 12 percent female, according to a study published in 2013. Another analysis, posted on the Coursera blog earlier this year, found that female enrollment in the company’s courses was lowest — around 20 percent — in subjects like computer science, engineering, and mathematics.
Instead of lecturing these lost souls, it’s up to educators and mentors to find ways on how to lure them back into learning. It can be through constant motivation and pep talk. Sometimes, it can be a great story that will push them to work harder.
