The quality of your grade three teachers matter throughout life

  • The Importance of Teacher Quality – From an interview with he John Bates Clark medal winning economist Raj Chetty: “Much to our surprise, it immediately became evident that students who were assigned to high value-added teachers showed substantially larger gains in terms of earnings, college attendance rates, significantly lower teenage birth rates; they lived in better neighborhoods as adults; they had higher levels of retirement savings. Across a broad spectrum of outcomes, there were quite substantial and meaningful impacts on children’s long-term success, despite seeing the same fade-out pattern for test scores.”
  • Politicians ought to have a pint with their opponents more often – Politics without blind tribal dogma? I’ll drink to that.
  • The more things shuffle, more they stay the same – “Reshuffling the cabinet is like changing who wears which colour skivvy in the Wiggles: it doesn’t make any difference, and they all end up singing the same old tunes, writes Tim Dunlop.”
  • France PM calls for calm after spate of attacks – “French authorities have called for calm after a string of attacks across the country left dozens of people injured, saying there was no evidence to connect the spate of violent acts.”
  • Is Saudi Arabia Trying to Cripple American Fracking? Well, it’s said as much, but the real reason for the flood of new Saudi oil is more complicated. “Saudi Arabia isn’t flooding the oil market to cripple America’s shale revolution, it’s doing it to win favor with Washington by weakening Russia and Iran.”
  • Average temperature in Finland has risen by more than two degrees – “According to a recent University of Eastern Finland and Finnish Meteorological Institute study, the rise in the temperature has been especially fast over the past 40 years, with the temperature rising by more than 0.2 degrees per decade. “The biggest temperature rise has coincided with November, December and January. Temperatures have also risen faster than the annual average in the spring months, i.e., March, April and May. In the summer months, however, the temperature rise has not been as significant,” says Professor Ari Laaksonen of the University of Eastern Finland and the Finnish Meteorological Institute. As a result of the temperature rising, lakes in Finland get their ice cover later than before, and the ice cover also melts away earlier in the spring. “
