"The whole people must take upon themselves the education of the whole people and be willing to bear the expenses of it. There should not be a district of one mile square, without a school in it, not founded by a charitable individual, but maintained at the public expense of the people themselves." -- John Adams

"No money shall be drawn from the treasury, for the benefit of any religious or theological institution." -- Indiana Constitution Article 1, Section 6.

"...no man shall be compelled to frequent or support any religious worship, place, or ministry whatsoever, nor shall be enforced, restrained, molested, or burthened in his body or goods, nor shall otherwise suffer on account of his religious opinions or belief; but that all men shall be free to profess, and by argument to maintain, their opinion in matters of religion, and that the same shall in no wise diminish enlarge, or affect their civil capacities." – Thomas Jefferson

THE DISRESPECT OF TEACHERS

Our Public Schools Aren’t Failing; We’re Failing Our Public Schools

As professionals, teachers are disrespected.

Ed reformers blame teachers for "failing schools" but that's because the truth is closer to home. Here we read about Michigan's "failing schools" caused by legislative neglect or, more likely, legislative abuse.
The state’s public schools were once admired across the nation. They were well-funded and supported, and provided an excellent education for children. These schools became “the center of community life” in many places in the state, and still do in many communities.

But our state’s “new landlord”, aided and abetted by the “multi-level marketing robber barons” of West Michigan, stopped funding our schools, allowing too many of them, especially in our largest cities, to fall into neglect and disrepair. Michigan’s last governor took $1 billion from the state’s education fund, while declaring himself the “education governor”, and we wonder why Detroit’s schools don’t have the resources needed to maintain their facilities, or pay their teachers a competitive salary. Our current Secretary of Education suggested the best solution to the problems with Detroit’s schools would be to simply shut down the entire district, and let families find other places to send their children–and this is the person in charge of the nation’s public schools.


Teachers not appointed to governor's teacher compensation commission

As professionals, teachers are disrespected.

The State Board of Accounts includes CPAs...the Native American Indiana Affairs Commission includes members of local Native Americans...

But a commission directly affecting teachers in Indiana has no teacher as a voting member.
Gov. Eric Holcomb followed through Tuesday on his pledge to charge a state commission with finding ways to make Indiana teacher pay more competitive with neighboring states.

However, none of the seven voting members of the Next Level Teacher Compensation Commission is a teacher.

At What Point Do We Stop Blaming Teachers?

As professionals, teachers are disrespected.

State legislatures and policy makers choose how and what teachers must teach. When their choices don't improve achievement, however, the teachers are the ones who are blamed...
As a teacher who has been told to teach a program as it’s written, how the hell is it my fault if the assignments students get are not challenging enough? I’m not the one who designed the assignments.

If you’re requiring me to read from some stupid script written by publishers who’ve never met my students, then how can you fairly evaluate my instruction? It’s not my instruction.

Should we be surprised that students aren’t engaged during a lesson that’s delivered by a teacher who had no hand in creating it and who sees it as the contrived lump that it is? I’m not a terrible actor, but hand me a lemon and I’m going to have trouble convincing even the most eager-to-learn student that I’m giving them lemonade.


THE BENEFIT OF HOME LIBRARIES

Home Libraries Confer Long-Term Benefits

Reading aloud to children is the single most important activity that parents and caregivers can do to help children become readers and achieve success in school. The study linked here reinforces the benefits of living in a book-oriented environment and explains that it has life-long benefits. Unfortunately, not all parents are able to afford the books for a home library or even provide transportation to public libraries.

Fortunately, there are a few sources of free books for children.
We've known for a while that home libraries are strongly linked to children's academic achievement. What's less certain is whether the benefits they bestow have a long-term impact.

A new large-scale study, featuring data from 31 countries, reports they do indeed. It finds the advantages of growing up in a book-filled home can be measured well into adulthood.


MATH IS FOR GIRLS, TOO

No intrinsic gender differences in children’s earliest numerical abilities

It turns out that men don't have any more "natural" inclination for math then do women.
Across all stages of numerical development, analyses consistently revealed that boys and girls do not differ in early quantitative and mathematical ability. These findings indicate that boys and girls are equally equipped to reason about mathematics during early childhood.

LOOKING BACK

Here are two posts from the past which are still relevant to today's educational environment.

Poverty Limits Student Achievement

Poverty and Potential: Out-of-School Factors and School Success

David C. Berliner's 2009 report explains the ways that poverty impacts student achievement. We must address poverty at the same time as we address school achievement or we're doomed to fail. Legislators who blame teachers or students for "failing schools" must take responsibility for their own failure to create an equitable society. They must provide high-poverty schools with the resources needed to counteract the out-of-school factors impacting student achievement.
Because America’s schools are so highly segregated by income, race, and ethnicity, problems related to poverty occur simultaneously, with greater frequency, and act cumulatively in schools serving disadvantaged communities. These schools, therefore, face significantly greater challenges than schools serving wealthier children, and their limited resources are often overwhelmed. Efforts to improve educational outcomes in these schools, attempting to drive change through test-based accountability, are thus unlikely to succeed unless accompanied by policies to address the OSFs that negatively affect large numbers of our nations’ students. Poverty limits student potential; inputs to schools affect outputs from them.


The Schools All Children Deserve

A Bill of Rights for School Children

Russ Walsh's 2016 book, A Parent's Guide to Public Education in the 21st Century, contains this gem, a Bill of Rights for School Children, first published on his blog.

Fulfilling the items on this list would go a long way to providing equitable educational opportunities for all children.
As we look to future, it may be useful to consider some principles about public education that, for me at least, seem immutable. A Bill of Rights for the school child if you will.

1. Every child has a right to a free, high quality, public education.

2. Every child has a right to attend a well-staffed, well-resourced, clean and safe local neighborhood school.

3. Every child has the right to be taught by well-informed, fully certified, fully engaged teachers who care about the child as a learner and as a person.

4. Every child has the right to a school that provides a rich and varied curriculum that includes the visual and performing arts, integrated technology, and physical education.

5. Every child has a right to a school that provides a rich and varied extra-curricular program including athletics, clubs, and service learning opportunities.

6. Every child has a right to instruction that is well-planned, engaging, and collaborative.

7. Every child has a right to instruction that is developmentally appropriate.

8. Every elementary school child has a right to daily recess.

9. Every child has the right to go to a school with adequate support personnel including librarians, nurses, guidance counselors, and learning support specialists.

10. Every child has a right to an element of choice in the educational program, including the right to choose to take advanced level courses.

Pi Day, 2014

Happy Pi Day


Just wait till next year!

March 14 is chosen as the day to celebrate pi, because the numerical date, 3/14, represents the first 3 digits of pi. Hardcore Pi Day celebrants are planning special events for 9:26:53 a.m. on March 14, 2015, as the numerical date 3/14/15 9:26:53 represents the first 7 digits of pi, 3.141592653.


A Brief History of π from San Francisco's Exploratorium

Pi has been known for almost 4000 years—but even if we calculated the number of seconds in those 4000 years and calculated pi to that number of places, we would still only be approximating its actual value. Here’s a brief history of finding pi:

The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. One Babylonian tablet (ca. 1900–1680 BC) indicates a value of 3.125 for pi, which is a closer approximation.

The Rhind Papyrus (ca.1650 BC) gives us insight into the mathematics of ancient Egypt. The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for pi.

The first calculation of pi was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world. Archimedes approximated the area of a circle by using the Pythagorean Theorem to find the areas of two regular polygons: the polygon inscribed within the circle and the polygon within which the circle was circumscribed. Since the actual area of the circle lies between the areas of the inscribed and circumscribed polygons, the areas of the polygons gave upper and lower bounds for the area of the circle. Archimedes knew that he had not found the value of pi but only an approximation within those limits. In this way, Archimedes showed that pi is between 3 1/7 and 3 10/71.

A similar approach was used by Zu Chongzhi (429–501), a brilliant Chinese mathematician and astronomer. Zu Chongzhi would not have been familiar with Archimedes’ method—but because his book has been lost, little is known of his work. He calculated the value of the ratio of the circumference of a circle to its diameter to be 355/113. To compute this accuracy for pi, he must have started with an inscribed regular 24,576-gon and performed lengthy calculations involving hundreds of square roots carried out to 9 decimal places.

Mathematicians began using the Greek letter π in the 1700s. Introduced by William Jones in 1706, use of the symbol was popularized by Leonhard Euler, who adopted it in 1737.

An Eighteenth century French mathematician named Georges Buffon devised a way to calculate pi based on probability. You can try it yourself at the Exploratorium's Pi Toss exhibit.

All who envision a more just, progressive and fair society cannot ignore the battle for our nation’s educational future. Principals fighting for better schools, teachers fighting for better classrooms, students fighting for greater opportunities, parents fighting for a future worthy of their child’s promise: their fight is our fight. We must all join in.

Are Our Children Failing Math and Science?

Why are our children failing in Math and Science? This is the question that a Scientific American article, Building a Better Science Teacher (login required)
In recent years a mounting stack of research has shown that a good teacher is the single most important variable in boosting student achievement in every subject. A good teacher trumps such factors as socioeconomic status, class size, curriculum design and parents' educational levels. Stanford University's Eric Hanushek showed that students of highly effective teachers make about three times the academic gains of those with less talented teachers, regardless of the students' demographics. That is exactly the trouble with math and science education: there are too few teachers like Bellucci. The teacher dropout rate is high, and the education system rewards the teachers it has for the wrong reasons.
David Berliner, on the other hand, provides research which proves that a good teacher is the greatest in-school factor, but no matter how good the teacher is, out of school factors still account for a greater impact on a child's achievement.

Susan Ohanian deconstructs the article and reminds us that the author, Pat Wingert, was the co-author of the Newsweek piece, Why We Must Fire Failing Teachers in 2010. In that article Wengert and her co-author wrote,
The relative decline of American education at the elementary- and high-school levels has long been a national embarrassment as well as a threat to the nation's future. Once upon a time, American students tested better than any other students in the world. Now, ranked against European schoolchildren, America does about as well as Lithuania, behind at least 10 other nations.
Diane Ravitch tells us, however,
the US was never first on international tests. When the first test was given in 1964 (a test of math), our students came in 11th out of 12.
It seems that Wengert's phrase once upon a time is indicative of a fairly tale, after all.

Newsweek continued,
For much of this time—roughly the last half century—professional educators believed that if they could only find the right pedagogy, the right method of instruction, all would be well. They tried New Math, open classrooms, Whole Language—but nothing seemed to achieve significant or lasting improvements.
Jim Horn at Schools Matter, responded...
Sadly, the group of educational antiquarians who have been in charge of national ed policy for the past 30 years continue to ignore the failure of their own failed and repeatedly failed test and punish policies that have turned American schools toward penal pedagogy as a solution to low test scores that are getting worse as poverty gets worse. The canaries in this deepening and empty mineshaft of the reform schoolers are, of course, the children, the poorest and the most vulnerable.
Newsweek went on...
It is difficult to dislodge the educational establishment. In New Orleans, a hurricane was required: Since Katrina, New Orleans has made more educational progress than any other city, largely because the public-school system was wiped out. Using nonunion charter schools, New Orleans has been able to measure teacher performance in ways that the teachers' unions have long and bitterly resisted.
The method used to "measure teacher performance" is undoubtedly using student test scores and/or VAM to evaluate teachers. We have discussed frequently how student test scores are an invalid measure of teacher effectiveness. Fair, Fairness and Accuracy in Reporting had this to say...
Many of these ideas are the subject of intense debate–research on charter schools has generally not shown substantial improvement over conventional public schooling, for example. Experts and advocates disagree with the notion that New Orleans is a success story. But Newsweek presents little debate–sticking with the right-leaning narrative version of "school reform" that is primarily about bashing teachers.
[Interestingly enough, the Scientific American article discussed teacher education, and said,
Whereas TNTP—like Teach for America—gets criticized by advocates of teacher colleges for their condensed training schedule, alternative programs that recruit people with deep content knowledge are an essential piece of the STEM solution, Daly says. "If you don't offer alternative certification, will anyone volunteer to do this?" he asks. "I would argue that the answer is no—no one will take on midcareer financial hardship when they have a mortgage and a family to go back to school to become a teacher. The number interested in doing that is zero."
The author also emphasized the high turnover rate with beginning teachers. I am especially taken by the phrase, "no one will take on midcareer financial hardship." Going back to school to learn to be an educator isn't worth the money when "anyone" can do it.]

Stephen Krashen has written a letter in response to Scientific American...it was published by Susan Ohanian. There is no indication that it was published by Scientific American. Dr. Krashen wrote,
Scientific American thinks that high science standards are the reason some states do better than others on science tests (Can the US get an ‘A’ in Science? August 2012). There is no evidence this is so. The two top states, in science, as mentioned by Scientific American, are Massachusetts and Minnesota. They also rank near the bottom of the country in percentage of children living in poverty.

Study after study has shown that children who come from high-poverty families do poorly on standardized tests, and the factors related to poverty, insufficient food quality and quantity, lack of health care, and lack of access to books, have been shown to be strongly related to student achievement.

American children from middle class families who attend well-funded schools score at the top of the world on standardized tests, including math and science. Our mediocre overall scores are because of our unacceptably high level of poverty: 23% of our children live in poverty, which ranks us 34th out of 35 economically advanced countries.

The problem is poverty, not lack of high standards.
