“There are other issues that need to be included, even if there are no problems with erasures. States report scaled scores. They can and do change the conversion rate from raw to scaled in order to show “improvement” year to year. The year before I taught in Virginia the school in which I taught had a 58% pass rate on the Middle School American History test. The year I was there the pass rate was 81%, my own was 89%. Sounds great, right? Except they had lowered the cut score and changed the conversion. If the previous year’s raw scores had been converted using the same matrix, the score would have been 71% or so. Thus we showed “improvement” but not that much.”

Here is a good account of the plans that Bill Gates and Rupert Murdoch have for your child’s personal information.

Hey, the data will generate a $20 billion industry. Not for you, of course.

I got to this article in the WSJ through the Naked Capitalism blog I read daily:

The Naked Capitalism blog also included a link to this article from 2006 on the same topic:

I forward these because I think they explain why school boards and politicians are hoodwinked by VAM. I know enough about statistics to know that VAM is junk science… but most people (and especially businessmen) want to believe everything can be reduced to a mathematical model and so we find ourselves in VAM-land.

When I worked in the federal Department of Education twenty years ago, I recall getting blizzards of postcards and letters from individuals and groups that were worried that the government was collecting too much information about them or their children. I pointed out repeatedly that the National Assessment of Educational Progress, which was in my tiny domain, did not collect information about individual students or their families. There was no vast federal storehouse of information about people.

Now I am no so sure. A reader just sent this announcement in a comment.

Here is the full comment:

In October, while announcing a series of actions to lower student loan payments, President Obama tasked the US Chief Technology Officer with further leveraging data and technology to help provide students and parents with more comparative information about college costs and college aid, so they can make more informed decisions about where to enroll.

This morning, the Administration announced several public- and private-sector initiatives—including the launch of education.data.gov, the latest in a growing number of data.gov communities—that respond to and even reach beyond the President’s call, in order to unlock the power of education data to make it accessible and useful for all Americans.http://www.whitehouse.gov/sites/default/files/microsites/ostp/ed_data_commitments_1-19-12.pdf

MAKE SURE YOU LOOK AT THE WHITE HOUSE COMMITMENTS TO:
The California Department of Education
The New York State Department of Education
The Michigan and Florida Departments of Education
Houghton Mifflin Harcourt
Pearson
JISC/UK, a technology branch of the UK Government
ETS, in cooperation with StraighterLine

How have we managed to survive all these years without a “Learning Registry” or  ”MyData” button?

The data-gathering seems to have no end point. I recently asked someone who works for a higher education association why the federal government was pressuring independent colleges to join the data hunt, and he said that the goal was to ascertain whether a grade in University A was the same as a grade in University B. I wondered why the federal government wanted to know this. He had no answer.
