When middle school math teachers completed an online professional development program that uses artificial intelligence to improve their math knowledge and teaching skills, their students’ math performance improved.My colleagues and I developed this online professional development program, which relies on a virtual facilitator that can – among other things – present problems to the teacher around teaching math and provide feedback on the teacher’s answers.Our goal was to enhance teachers ...read more
The sore throat. The packed and painful sinuses. The fatigue. Sure, it’s “just a cold,” but it can feel miserable.

In 2017, Jim Webster began going out at night near his New Jersey home to take pictures of our galaxy. With a 14-millimeter lens and a DSLR, he would capture long exposures of the Milky Way galaxy, revealing the delicate filaments of nebulae and countless clusters of stars hidden within the band of the galaxy’s arm.It was a rekindling of a childhood passion for science and astronomy, first sparked by learning about the Apollo program at school. At home, Webster would stick his telescope out of ...read more
When it comes to the great mathematical problems of the 21st century, the conundrums of jigsaws have been unjustly overlooked for too long. All that now changes thanks to the work of Madeleine Bonsma-Fisher, a data scientist at the University of Toronto and Kent Bonsma-Fisher, a quantum physicist, who have settled a problem that has bedeviled puzzlers the world over.The question at the heart of their endeavor is this: if you have a jigsaw of N pieces that once assembled, fills an area equal to A ...read more
