9/25/14 Today's Inquiries

Original flavor. No sugar added.

Sometimes people write terrible headlines: Can brain based learning change the classroom? As opposed to what other kind of learning?

Also from EdSurge: Where does automated essay scoring belong in K-12 education? I'm deeply skeptical of it as an actual grating tool (see what I did there). However, I like what the author suggests about giving the kids access to the scoring tool as a kind of proof reading guide. So long as it gives decent feedback and helps with the mechanics of writing, it could be very valuable and frees up the teacher to perform other tasks.

It looks like we're getting gifted education all wrong. If you don't want to read the whole .pdf read Libby Nelson's take here.
We use data from a large urban school district to study the impacts of assignment to separate gifted classrooms on three distinct groups of fourth grade students: non-disadvantaged students with IQ scores ≥130; subsidized lunch participants and English language learners with IQ scores ≥116; and students who miss the IQ thresholds but scored highest among their school/grade cohort in state-wide achievement tests in the previous year. Regression discontinuity estimates based on the IQ thresholds for the first two groups show no effects on reading or math achievement at the end of fourth grade. In contrast, estimates based on test score ranks for the third group show significant gains in reading and math, concentrated among lower-income and black and Hispanic students. The math gains persist to fifth grade and are also reflected in fifth grade science scores. Our findings suggest that a separate classroom environment is more effective for students selected on past achievement – particularly disadvantaged students who are often excluded from gifted and talented programs. 
A study of MIT's physical vs online physics course shows that "unprepared" online students have the highest test score growth.

Good on these kids for protesting stupid right wing changes to their history curriculum.

Lots of data about childhood hunger but I don't necessarily agree with the poster's conclusion. While helping poor parents make better decisions is a good thing, the language of responsibility is often a back door to victim blaming and calls for cutting aid to the "undeserving."

Whites who drop out of high school have more wealth than blacks or hispanics who graduate. From college.

The police killed a black man for walking around Walmart with an airsoft gun he bought from the sporting goods section at Walmart. Oh, and he dropped the gun and surrendered to police when they shot him. Local authorities decided no to investigate so the Feds have stepped in.

How does the rise of urban living affect human sexual selection?

A recent history of moral hazard and the 1998 bailout of Longterm Capital Management. Really setting the stage for 2008.
Still, the lesson learned was that in the event of troubles, the Fed could be counted on to lend a hand to a) avoid disruption; b) add liquidity and; c) protect the Street against catastrophic losses. In hindsight, it looks like the lessons learned were the wrong ones.
A libertarian interviews Piketty, auto of the podcast included in the link. I haven't listened yet but I've enjoyed past podcasts by Mr. Roberts and have every expectation of quality.

In case you were worried, a pentagon spokesperson confirmed that attacks against Eurasia ISIS could last for years. Thank goodness, I was thinking this might be a short war.

Is the profession of science broken? Does Space Pope have scales?

And, how to manage privilege.
