Affective Polarization or Partisan Disdain?: Untangling a Dislike for the Opposing Party from a Dislike of Partisanship

"Relying on two national experiments, we demonstrate that although some Americans are politically polarized, more simply want to avoid talking about politics. In fact, many people do not want their child to marry someone from their own party if that hypothetical in-law were to discuss politics frequently."

Implementing the flipped classroom: an exploration of study behaviour and student performance

Surprise, surprise: Looks like flipped classroom environments - which swap the venue in which traditional teaching and "homework" are done - are overhyped.

Heat and Learning

"We provide the first evidence that cumulative heat exposure inhibits cognitive skill development and that school air conditioning can mitigate this effect. Student fixed effects models using 10 million PSAT-takers show that hotter school days in the year prior to the test reduce learning, with extreme heat being particularly damaging and larger effects for low income and minority students. ... New data providing the first measures of school-level air conditioning penetration across the US suggest such infrastructure almost entirely offsets these effects."

Did Rwanda’s Paul Kagame trigger the genocide of his own people?

"Millions of lives were lost in the ethnic and political violence that embroiled Rwanda in the 1990s. Rwanda’s current president Paul Kagame was initially hailed as a hero for stopping the genocide, but, as Canadian journalist Judi Rever reveals in her new book, the truth is much darker".
