Back to campus for the fall semester 8/17/2013
It is that time of the year. The final weekend before classes start. Saw this article online, although a bit of hand wringing about the state of governmental oversight of education ... there are some interesting tidbits to glean about the state of "teach to the test".
Warnings from the Trenches A high school teacher tells college educators what they can expect in the wake of No Child Left Behind and Race to the Top. By Kenneth Bernstein Academe, the journal of the American Association of University Professors.
Brilliant Blog article on an academic article from Roediger and Pyc in the December 2012 issue of the Journal of Applied Research in Memory and Cognition. Asks the question: Why are we spending millions upon millions of dollars on unproven technologies, when there are so many empirically-proven techniques from cognitive science and psychology that are going virtually unused?

Excel Spreadsheet errors
At this point, JP Morgan’s legal compliance and top executives, as well as a slew of government officials and executives around the world, may wish they’d never heard of Excel. It has been linked to a series of missteps and blowups, including:
The “London Whale” trade - Due to an error in an Excel spreadsheet used to model risk, JP Morgan seriously underestimated the downside of its synthetic credit portfolio, which ultimately led to the bank to declare $6 billion in losses and could lead to another $600 million in fines. As James Kwak explains on Baseline Scenario, the errors stemmed from a combination of copy-paste mistakes and a faulty equation created to crunch the numbers.
Good to see that control and governance is part of the danger described: #5: Limited governance with spreadsheets -- Kugel's last point concerned control. He explained that while spreadsheets offer users a lot of freedom, it might be too much in the world of corporate finance. "Individuals can immediately translate their thoughts about what to present and how to present it in a format that makes sense to them; they can update and modify it whenever they wish, and the change is instantaneous," he said. "[But] the downside is it's just this thing that drives parallel data stores with inconsistent and inaccurate data."

- Researchers Finally Replicated Reinhart-Rogoff, and There Are Serious Problems. Spreadsheet issues discovered by Herndon, Ash, and Pollin: They find that three main issues stand out. First, Reinhart and Rogoff selectively exclude years of high debt and average growth. Second, they use a debatable method to weight the countries. Third, there also appears to be a coding error that excludes high-debt and average-growth countries. All three bias in favor of their result, and without them you don't get their controversial result.
