Gates Bracelets

[GeoDerek]

Educators remain critical of Microsoft founder's contributions to the education system. Bill Gate's foundation has been mining classroom data for years in an effort to determine how effective certain teaching methods are with students, but critics insist, rather than investigate teachers methods, they should focus more resources on improving, "the substance of what is being taught," in schools today.

Microsoft founder Bill Gates is funding research into using controversial bracelets to measure how engaged students are in a classroom.
About $US1.4 million ($1.4 million) from the Bill & Melinda Gates Foundation has been given to US university researchers,* who plan to use the "Q Sensors".
The sensors detect excitement, stress, fear, engagement, boredom and relaxation through the skin... The bracelets send a small current across the skin and measure changes in electrical charges as the sympathetic nervous system responds to stimuli.
