Parents have all sorts of concerns about their children when it comes to technology. Duke Professor Candice Odgers tells us which concerns her research shows are valid. 

Since the late 1990s, the academic performance of many students in London has risen dramatically – so much so, it now exceeds national averages. The improvement is due largely to big gains in the 13 districts of Inner London – places with the greatest concentrations of low-income and minority students. Sanford professor Helen “Sunny” Ladd spent a month in two of those boroughs, Tower Hamlets and Hackney, in order to identify what policies are driving the change.

How should we determine whether children are actually learning in school? The U.S. has standardized testing, but some other countries have followed a different approach known as "inspection and review". Sanford professor Helen "Sunny" Ladd thinks such an approach shows great promise.
