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.
