Politico reports this morning:

 

 

PARCC says many states with Common Core-based assessments will use automated scoring for student essays this year. A spokesman says that in these states, about two-thirds of all student essays will be scored automatically, while one-third will be human-scored. As in the past, a spokesman said about 10 percent of all responses will be randomly selected to receive a second score as part of a general check. States can still opt to have all essays hand-scored.

 

This is another reason to opt out of the state testing.

 

Do you think that PARCC is unaware of the studies by Les Perelman at MIT that show the inadequacy of computer-graded scoring of essays?

 

Here is a quote from an interview with Professor Perelman, conducted by Steve Kolowich of the Chronicle of Higher Education:

 

 

“Les Perelman, a former director of undergraduate writing at the Massachusetts Institute of Technology, sits in his wife’s office and reads aloud from his latest essay.

 

“Privateness has not been and undoubtedly never will be lauded, precarious, and decent,” he reads. “Humankind will always subjugate privateness.”

 

Not exactly E.B. White. Then again, Mr. Perelman wrote the essay in less than one second, using the Basic Automatic B.S. Essay Language Generator, or Babel, a new piece of weaponry in his continuing war on automated essay-grading software.

 

“The Babel generator, which Mr. Perelman built with a team of students from MIT and Harvard University, can generate essays from scratch using as many as three keywords.

 

“For this essay, Mr. Perelman has entered only one keyword: “privacy.” With the click of a button, the program produced a string of bloated sentences that, though grammatically correct and structurally sound, have no coherent meaning. Not to humans, anyway. But Mr. Perelman is not trying to impress humans. He is trying to fool machines.

 

“Software vs. Software

 

“Critics of automated essay scoring are a small but lively band, and Mr. Perelman is perhaps the most theatrical. He has claimed to be able to guess, from across a room, the scores awarded to SAT essays, judging solely on the basis of length. (It’s a skill he happily demonstrated to a New York Times reporter in 2005.) In presentations, he likes to show how the Gettysburg Address would have scored poorly on the SAT writing test. (That test is graded by human readers, but Mr. Perelman says the rubric is so rigid, and time so short, that they may as well be robots.)

 

“In 2012 he published an essay that employed an obscenity (used as a technical term) 46 times, including in the title.

 

“Mr. Perelman’s fundamental problem with essay-grading automatons, he explains, is that they “are not measuring any of the real constructs that have to do with writing.” They cannot read meaning, and they cannot check facts. More to the point, they cannot tell gibberish from lucid writing.”

A Korean grandmaster of the game Go finally beat a computer designed by Google. 

 

After losing three times in a row, Lee Sedol finally found weaknesses in the computer that beat him.

 

Lee had said earlier in the series, which began last week, that he was unable to beat AlphaGo because he could not find any weaknesses in the software’s strategy.

 

But after Sunday’s match, the 33-year-old South Korean Go grandmaster, who has won 18 international championships, said he found two weaknesses in the artificial intelligence program.

 

Lee said that when he made an unexpected move, AlphaGo responded with a move as if the program had a bug, indicating that the machine lacked the ability to deal with surprises.

 

AlphaGo also had more difficulty when it played with a black stone, according to Lee. In Go, two players take turns putting black or white stones on a 19-by-19-line grid, with a goal of putting more territory under one’s control. A player with a black stone plays first and a white-stone player gets extra points to compensate.

 

Lee played with a white stone on Sunday. For the final match of the series, scheduled for Tuesday, Lee has offered to play with a black stone, saying it would make a victory more meaningful.

 

South Korean commentators could not hide their excitement three hours into Sunday’s match, when it became clear that Lee would finally notch a win. AlphaGo narrowed the gap with Lee, but could not overtake him, resigning nearly five hours into the game.

 

I am for the human. Let the machines cheer for the machine.

Peter Greene eviscerates an article advocating competency based education for teacher education.

The claim for technology starts with the assertion that traditional teacher education is worthless, which explains why there are so many bad teachers. But you don’t have to be a fan of such programs to object to a technological fix.

Greene writes:

“Let me step aside for a moment to note that I am not the person you want to defend traditional teacher prep programs. I was trained in a non-traditional program with far fewer hours of education courses before student teaching and far more support and coursework while I was getting my classroom practice on. I happily await the day that some college education department calls me up and invites me to re-configure their system, because I have more than a few ideas.

“I should also note that debating study versus practice in teacher prep strikes me as just as useful as endlessly arguing about whether there should be more hugging or kissing with your romantic partner. If you are arguing violently for mostly one at the exclusion of the other, you’ve lost sight of the point.”

“I’m a little nervous that Riccards is dreaming of an EdTPA type of program, with videos and a set of standard behaviors that can be evaluated at a distance. That idea is a snare and a delusion. It does not work. It will never work.

“This also feels like one of those attempts to remove subjective personal judgment from the process. That is also a snare and a delusion.

“Teachers have to be educated by other teachers. That is why student teaching works– daily constant supervision and feedback by a master teacher who knows what she’s doing. That experience is best when it rests on a foundation of subject matter, child development, and pedagogical knowledge. It also works best when the student teacher is helped to find her own teacher voice; co-operating teachers who try to mold mini-me’s are not helpful.

“The computer era has led to the resurrection of CBE because computing capacities promise the capability of an enormously complicated Choose Your Own Adventure individualized approach to learning– but that capacity is still not enough for any sort of learning that goes beyond fairly simple, tightly focused tasks. Sure– creating a CBE teacher prep program would be super easy– all you have to do is write out a response for every possible combination of teacher, students and content in the world. And then link it all together in a tagged and sequenced program. And then come up with a clear, objective way to measure every conceivable competency, from “Teacher makes six year old who’s sad about his sick dog comfortable with solving a two-digit addition problem when he didn’t actually raise his hand” to “Teacher is able to engage two burly sixteen-year-old males who are close to having a fist fight over the one guy’s sister to discuss tonal implications of Shakespeare’s use of prose interludes in Romeo and Juliet.”

We count on Peter to be the voice of common sense and experience.

Caitlin Emma reports in Politico from the SXSW conference in Austin, Texas, where thousands of ed tech entrepreneurs meet and greet:

 

 

DISPATCH FROM SXSWedu: Thousands of students have indicated that they’re interested in getting credit since Arizona State University and edX announced [http://politico.pro/1UbIAgi ] a partnership last year to make freshman year available to students entirely online, allowing students to complete the courses and then decide later whether they want to pay for academic credit. edX CEO Anant Agarwal told our own Caitlin Emma at SXSWedu in Austin that while just 323 learners were actually eligible for credit in the Global Freshman Academy’s first year, he expects that to grow. Having online courses deliver real credit has rocketed edX into an era of “MOOCS 2.0,” he said. Thinking ahead, Agarwal said he’s also focused on a recent announcement [http://bit.ly/1U28unX ] to pilot “MicroMaster’s,” which will allow learners to take a semester of courses online and then spend a single semester on campus. The pilot now offers only the courses in “supply chain management,” but Agarwal said he hopes to expand it to dozens of subject areas in the coming years.

 

 

ARIZONA’S APPETITE FOR A MENU OF TESTS: There’s a good chance that Republican Arizona Gov. Doug Ducey will sign a bill that would make the state the first in the nation to offer schools a menu of assessment options. The legislation doesn’t let parents opt children out of tests, but would comes as the opt-out movement warns of another strong showing this spring. The state board would have to approve alternative tests. State lawmakers envision a scenario where schools use the ACT instead of the state standardized test, for example. The Obama administration has supported some states that wanted to move from the state test to the ACT or SAT in high school for accountability. And the Every Student Succeeds Act provides states with the flexibility to pursue this option. But federal officials might take issue with individual schools using different tests for accountability because it could become difficult to measure student learning across the state and hold all schools accountable to a similar standard. More in The Republic: http://bit.ly/1UcaNng.

 

 

As I have said many times on this blog, standardized tests should never be used as a graduation requirement or for accountability. An accountability test should be akin to a test for a driver’s license, not norm-referenced. This is called a criterion-referenced test. Everyone who is able to meet the agreed-upon requirements should be able to do so. A norm-referenced test guarantees that a certain proportion must fail.

As we have seen again and again, in the rhetoric  of the Gates Foundation, Mark Zuckerberg, and assorted tech entrepreneurs, “personalized learning” means learning on a machine. In typical corporate reform talk, where up means down and reform means destruction, personalized means impersonalized.

 

And here it comes, as described by Politico Education:

 

“DISPATCH FROM SXSWedu: “Who here has ever complained about No Child Left Behind?” iNACOL President and CEO Susan Patrick asked a room full of people during a panel discussion at SXSWedu in Austin. The vast majority of hands shot up, our own Caitlin Emma reports. “The future is now,” she said. The Every Student Succeeds Act represents an “incredible opportunity,” Lillian Pace of KnowledgeWorks said: States couldn’t fully implement personalized learning systems under No Child Left Behind, but now there’s an opportunity to do something different. That’s particularly true when it comes to testing, she said. And there’s been a lot of discussion at SXSWedu about what New Hampshire is already doing with its Performance Assessment for Competency Education pilot. It took a while to get federal officials on board, New Hampshire Deputy Education Commissioner Paul Leather said. Leather said he first pitched former Education Secretary Arne Duncan on the idea just six months into the Obama administration. But Duncan told Leather to come back when the idea was more fully formed. So Leather did and blew Duncan away with his presentation: New Hampshire’s assessment pilot received federal approval last year.

 

“- Leather said his state has been working on competency education for about two decades. “It’s not a Johnny come lately” idea for the state and it shouldn’t be one for other states, he said. Seven states will have the opportunity to pilot [http://politico.pro/1QCPQAx ] innovative assessment systems under ESSA. But New Hampshire is a pioneer and for most states that are considering applying for the pilot, it’s their only frame of reference for an innovative assessment system, Pace said. States considering these systems should think carefully about what works best for them, Leather said – because what works for New Hampshire won’t necessarily work everywhere.”

 

Mate Wierdl is a professor of mathematical sciences at the University of Memphis and a frequent commenter on the blog.

 

 

He writes:

 

 

“In math education, there’s not a single thing computers do that is necessary for a great math class. Not one. Occasional calculations? A $5 calculator does everything needed, and even at the university, a $30 Casio can even do symbolic calculations so it does more than needed. But of course, all calculations can be done by hand.

 

“There’s a free software called Sagemath. It does all possible math and statistics (and chemistry, etc) related calculations, visualizations. It can be used online or can be installed on any computer. At the university, I show it to the kids where it can be accessed. That’s all they need. It’s simple to use, and it has a freely available user guide. At home or library or computer lab, kids can use it as much as they want to. They can use it to check the solutions to all their home work, or they can do experiments with it.

 

“But whatever Sagemath can do has nothing to do with great math teaching. Great teaching is done by great teachers, so there is no choice between tablets and teachers when it comes to students’ need.

 

“If teachers’ pay doesn’t keep up with inflation, the quality of teaching will decline. If you don’t use computers in classes, quality of teaching doesn’t decline.

 

“So that’s where my priorities are: in great teaching. I believe, that’s very much in the interest of students, isn’t it?

 

“Before making yet more assumptions about my motives or state of mind, also consider the fact that I maintain computers, email and web servers, various free software, and each year I evaluate the newest software offerings that are supposed to help teachers in their work.

 

“Without exception, they are designed to take over a teachers’ job by distorting what math education is supposed to be. Kids, and that includes my daughter in 10th grade and my college freshman son, learn to press buttons, do calculations, enter solutions online with cumbersome interfaces instead of learning real math—math that would be useful and interesting for them.

 

“My daughter comes home every day and demands me to explain what she really learned in math because in class she just “learned which buttons to push to get the answers.”

 

“This pragmatic push to perceive math as a subject to get correct answers via calculations truly destroys math education.”

Superintendents in Connecticut (CAPSS) have endorsed the idea of putting children in front of machines and calling it “personalized learning.” As Wendy Lecker shows in this post, this machine work is neither “personalized” nor is it “learning.”

 

How can a machine be more “personal” than a human?

 

 

Lecker writes:

 

 

In CAPSS’ incoherent version, schools will no longer be age-graded, students will design their own curricula and progress when they develop “competencies” rather than completing a school year. Rather than being grouped according to age, students will be grouped according to “mastery.” In order to progress to the next level, children will have to undergo four standardized tests a year.
Of course, any system that depends on standardized tests for advancement cannot be “personalized.” In addition, the CAPSS plan institutionalizes tracking; a harmful educational practice rejected by the Connecticut State Board of Education. Worse still, CAPSS’ version of tracking, where there is no age-grading, would humiliate a student who fares poorly on standardized tests by grouping her with children years younger than she.
The CAPSS muddled vision also proposes students not necessarily learn in school, meaning that much learning will be conducted online; a method with little evidence of success.

 

What should school look like?

 

 

If we are concerned with our children’s development into healthy responsible citizens, then personalization should mean that schools should focus on relationships — with humans, not computers. Relationships with teachers and other students are the key to keeping students engaged and in school. A longitudinal study of diverse California high schools confirmed previous research that students who feel connected to their teachers improve academically, engage in less risky behavior, and are more likely to complete high school.

 

Another recent study comparing “personalized learning” to a control group in traditional schools found that students in the control group “reported greater enjoyment and comfort in school, and felt their out-of-school work was more useful and connected to their in-school learning.” As Harvard economics professor N. Gregory Mankiw recently observed in the New York Times, “after 30 years as an educator, I am convinced that the ideal experience for a student is a small class that fosters personal interaction with a dedicated instructor.”
The need for human interaction to promote effective learning is rooted in brain development. As neuroscience expert Adele Diamond has written, the brain does not recognize a sharp division between cognitive, motor and emotional functioning. Thus, research has shown that feelings of social isolation impair reasoning, decision-making, selective attention in the face of distraction and decreases persistence on difficult problems….

 

A truly “personalized” education would ensure small classes with supports for every need; and a variety of subjects to develop students’ interests as well as their cognitive, motor and social capabilities….

 
Our children are complex, multi-dimensional beings who need deep and rich experiences to develop properly. They are not characters in a video game who just need enough points to jump to the next level. Anyone who cares about healthy child development should reject CAPSS’ narrow and de-personalized vision of learning.

 

 

“Personalized learning” on a machine is an oxymoron.

 

 

 

 

Governor Paul LePage is a Tea Party guy who has twice been elected governor of Maine. He prevailed each time in a three-way split.

As Peter Greene notes, Governor LePage is known for his bizarre statements. Among other things, he refused to attend an event honoring Martin Luther King, Jr. Day:

One of his first acts as governor was to refuse to attend a Martin Luther King Day breakfast and, when called on it, to tell the NAACP to kiss his butt. He also undid decades of environmental reguations, and took down a mural of labor history in the capitol, comparing it to North Korean brainswashing. He sabotaged a $120 million wind power plan.

He has gone through six education commissioners in three years. The last nominee might have had some trouble getting approved by the State Senate because he is a creationist.

Governor LePage is a strong supporter of charter schools, choice, digital learning, and competency based education (nonstop assessment by computers). He views public schools with contempt.

Early on in his first term, he embraced Jeb Bush’s digital learning plan and set about implementing it. One of the best exposes of our time was written by Colin Woodard about “The Profit Motive behind Virtual Schools in Maine.” That’s when many people recognized that the tech companies were giving money to Jeb Bush’s Foundation for Educational Excellence, and FEE was promoting the tech companies’ products. And it was all about profit.

Greene thinks that Governor LePage may crown himself King of Maine. One hopes that he will have only one opponent in the next election. He is an embarrassment to the state of Maine.

The Walton Family Foundation has been a key player in the movement to privatize public education. It recently pledged to pump $200 millions year into new charter schools to compete with public schools and drain away their resources.

Nonetheless, Walton published an editorial in Education Week admitting that online charter schools were a failure. Walton funded the research that showed their negative results.

“The results are, in a word, sobering. The CREDO study found that over the course of a school year, the students in virtual charters learned the equivalent of 180 fewer days in math and 72 fewer days in reading than their peers in traditional charter schools, on average.

“This is stark evidence that most online charters have a negative impact on students’ academic achievement. The results are particularly significant because of the reach and scope of online charters: They currently enroll some 200,000 children in 200 schools operating across 26 states. If virtual charters were grouped together and ranked as a single school district, it would be the ninth-largest in the country and among the worst-performing.

“Funders, educators, policymakers, and parents cannot in good conscience ignore the fact that students are falling a full year behind their peers in math and nearly half a school year in reading, annually. For operators and authorizers of these schools to do nothing would constitute nothing short of educational malpractice.”

Unfortunately, Walton doesn’t promise to stop funding these failed ideas. But it does promise to ask tough questions when the next online charter asks for money.

Fooled me once, shame on you.

Fooled me twice, shame on me.

Roxana Marachi, professor of education at San Jose State University in California, recently testified at a public hearing on ESSA about the dangers to children of excessive exposure to wireless radiation. She also expressed concern about the invalidity of the assessments now in use:

 

She wrote:

 

My letters outline grave concerns regarding unfair test administrations, security and privacy issues related to test data, violations of students’ rights, delivery of the tests on faulty networks and technology, and long-term motivational problems that are likely to result from misdiagnosing students with assessments unfit for use. In the medical community, such practices would constitute fraud.

 

Professor Marachi cites the latest scientific research about the effects of wireless radiation:

 

As of December 1st, two hundred seventeen scientists from forty nations have signed the International EMF Scientist Appeal. All have published peer-reviewed research on electromagnetic fields (EMF) and biology or health. The petition calls on the United Nations, the UN member states, and the World Health Organization (WHO) to adopt more protective exposure guidelines for EMF and wireless technology in the face of increasing evidence of health risks.

 

The scientists cite a 2011 study which documents how the industry-designed process for evaluating microwave radiation from phones results in children absorbing twice the radiation to their heads, up to triple in their brain’s hippocampus and hypothalamus, greater absorption in their eyes, and as much as 10 times more in their bone marrow when compared to adults.
