Dont Let Washington Become NJ
A well intentioned, partially informed and very political group of Washington citizens has convinced our Legislature to implement a 19th century mathematics curriculum in our schools. Since they believe that the half-century of work in mathematics education that started when Sputnik went up in 1957 was almost entirely misguided, they undervalue the ideas and research of the people who, in my lifetime, have worked hardest to better our children's learning of mathematics. Conversely, they tout the opinions of some of the louder research mathematicians who share their traditional views.
I am a mathematician with different views. I favor many progressive and reform ideas in mathematics education. But I am well aware that, as in other difficult areas of research and scholarship, mistakes are made, and ideas and opinions have to be abandoned or changed -- including some I once held.
Statements by practicing mathematicians should of course be taken seriously in mathematics education. Any reasonable person who has learned from mathematicians that there are an infinite number of primes would reject out of hand a fourth-grade curriculum built on a finite number of primes. The Washington State Board of Education would be justified in rejecting any curriculum that introduces real numbers in second grade, given that the mathematician it hired to review our state's standards has told them: "The point is that fractions are an essential intermediary step between whole number and real numbers." And since a renowned mathematician on the National Mathematics Advisory Panel recently convened by President Bush tells us that "...one must know what fractions are and how to add fractions before a decimal can be defined," surely no one should consider a curriculum that introduces decimals before fractions.
These two prominent mathematicians are honest, hard working scholars speaking the truth as they see it as a public service. Unfortunately, they often make statements about or in mathematics education and public policy in a manner that suggests these statements are mathematically certain. The two statements just quoted sound as if they are statements in mathematics. But they are not certain. In fact, they are not true.
There is a "naming trick" based on iterated halving with which second graders can understand and use real numbers, which they can call "measuring numbers," as "good names for dots on number lines." A six-year-old, who may or may not know what a tenth is, explains the trick in six minutes at http://www.youtube.com/watch?v=d90wWqYBMOQ
The idea behind this trick can be extended to decimals in third and fourth grades, before students have to face the horrors of fractions.
Mathematicians, it seems to me, have a special responsibility to be careful in how they speak to the lay public. Everybody knows that even the best knowledge in other fields is subject to revision, but that mathematics is different. I was told in high school chemistry 50 years ago that inert elements did not form compounds. Then along came xenon difluoride. I'm sure that our two mathematicians would agree that statements in mathematics education, including their own, have to be viewed and held more tentatively than those in chemistry.

Business leaders in control - please no
Why Business Leaders Should Not Be in the Driver's Seat
Our public schools were never perfect. There was never a golden age when everyone graduated high school and learned to a high standard of excellence. Improving education and expanding equality of opportunity have been the slow, steady work of generations.
Yet now, we live in an age when it is the custom to bash the public schools, not to thank them for helping to build our nation. It has become commonplace for the president, the secretary of education, and the leaders of the business community to lament the terrible state of our schools and to demand radical, one might even say revolutionary, changes. We live in an age of data, and the data (they say) are awful. They look at NAEP test scores, international test scores, graduation rates, and anything else that is measurable, and they demand solutions, now.
Note that they never speak of the state of learning, nor even the state of education, because those words connote many intangibles that cannot be measured and converted into data. The politicians and business leaders do not speak about whether young people read in their spare time, whether their reading consists of good literature and non-fiction, whether they know how to write an engaging essay or a well-constructed research paper, whether they can engage in an informed discussion of history, whether they are knowledgeable about our governmental system, whether they perform volunteer service in their community, whether they leave high school prepared to serve on a jury and vote thoughtfully.
No, instead what we now hear from our business leaders is that the schools must be redesigned to function like business. They conveniently overlook the fact that business practices and the ruthless pursuit of a competitive edge nearly destroyed our national economy a year ago.

Lame Duck Commissioner Acts
New Jersey's lame duck education commissioner, Lucille Davy, released the following statement this week:
In May 2010, all students enrolled in an Algebra I course will take the Algebra I End of Course (EOC) Assessment. This administration will act as a formative assessment in preparation for the spring 2011 administration when passing the Algebra I EOC will be a graduation requirement. We have examined the results of the May, 2009 administration and are very concerned about the performance of the students on this assessment.
Thus she has single handedly confused the entire NJ mathematics education community and the students of NJ as on one hand she has committed the state to the Achieve Benchmarks and the Algebra I exam and on the other hand she has committed to the Common Core Standards. Thus, schools will have to change curricula now to meet the first and then change again later to meet the second.

Race to the Top
With the Race to the Top (federal education stimulus money) about to begin. It is interesting to see the huge contrast between Pennsylvania (who will compete for the funds) and New Jersey (who needs to read it). Quotes (Philadelphia Inquirer - Nov 13th) from each top education official are below.
Pennsylvania Education Secretary Gerald Zahorchak said he welcomed the competition.
The availability of Race to the Top funds presents a tremendous opportunity for all Pennsylvania's schools to build on our academic gains, and we are poised to compete vigorously for these funds," Zahorchak said in a statement. Zahorchak said Pennsylvania was on track to be "one of the first" states to apply for Race to the Top money, he said. The deadline for the first round of applications is in January.
In contrast, New Jersey Education Secretary Lucille Davy said her department had just received the 200-page application and wanted to review it before commenting.

2009 NAEP
Highlights of the national results show that gains in overall average scores seen in earlier years did not continue at grade 4 but did continue at grade 8. While still higher than the scores in the six assessment years from 1990 to 2005, the overall average score for fourth-graders in 2009 was unchanged from the score in 2007. The upward trend seen in earlier assessments for eighth-graders continued with a 2-point increase from 2007 to 2009. There were no significant changes from 2007 to 2009 in the score gaps between White and Black students or between White and Hispanic students at either grade 4 or grade 8. State results for grade 4 show score increases since 2007 in 8 states and decreases in 4 states and jurisdictions. At grade 8, scores were higher in 2009 than in 2007 in 15 states and jurisdictions, and no states showed a decline. |

Outraged
Jo Boaler, Marie Curie Professor, University of Sussex (England), formerly of Stanford, writes in the Fall 2009 NCSM Newsletter.
Antireformists have worked actively, effectively, and in some cases unethically to oppose any changes to math teaching, but how wide is their influence? I now believe the groups have not only organized campaigns against change, they have also created a fiction around their own importance and they do not well represent the public. Those of us who work as educators and know about children’s learning of mathematics need to question how groups who oppose change have managed to have such influence, we also need to be outraged by what they have done and continue to do.
Dr. Boaler’s sentiments above are very true especially with respect to the current issues in NJ. We have a small group of antireformists that we should be outraged by. I encourage all to read Dr. Boaler’s work and her new book, What’s Math Got to Do with It? I even mailed a copy to the Commissioner to read. I have several copies in my office. If you want one at no cost, just send me an email.

Economic competitiveness
Education Week: Algebra 2 Test Yields Poor Results in Year II
States that voluntarily took part in a demanding test of advanced algebra skills, given for a second straight year, again saw large proportions of their students struggle with that math content. At least 80 percent of students in all 13 states that participated in the exam this spring failed to meet the test’s threshold for being repared for entry-level college math. That poor showing mirrored the results from last year, when the Algebra 2 test was first piloted. Four states also took part in a separate Algebra 1 test this year, and the scores were also weak.

Calculator Ban on NJASK
With this swift ban, there will be open ended (extended constructed response items) that will NOT allow a calculator in all grades. In fact, some ECR will allow a calculator and others will not. Moreover, the majority of items have NEVER been field tested without calculators but still will be operational without calculators this spring.
Instead of a clear strategy that would field test non calculator items and not allow calculator on computational items only, the commissioner has rushed to make a harmful decision to the students of NJ.

Quotation
"If a doctor, lawyer, or dentist had 40 people in his/her office at one time, all of whom had different needs, and some of whom didn't want to be there and were causing trouble, and the doctor, lawyer, or dentist, without assistance, had to treat them all with professional excellence for nine months, then he might have some conception of the classroom teacher's job."

Incorrect facts
Very interesting article by Cognitive psychologist Gordon H. Bower of Stanford University who looks at: Why is it hard to "unlearn" an incorrect fact?
Building on the correct information can help you learn new associations to it: add something to change how you retrieve the item from your memory. You might replace your question “Name of John’s wife?” with “Name of John’s second wife?”; or use an elaboration that contains the accurate information, such as “We are weird” or “My niece is nice”; or convert 7 X 9 into 7 X (10 – 1) = 70 – 7 = 63. As you practice the elaborated association, the simpler direct association (7 X 9 = 63) eventually replaces the earlier one, which weakens without rehearsals. Labeling and rehearsing the wrong association (for example, saying to yourself, “7 X 9 is not 63”), however, are distinctly counterproductive.

Common Core & Federal Dollars LInked?
An interesting editorial in the NY Times (July 30th). It clearly linked states' adoption of the Common Core Standards to Federal Government funds. See below:
The president and the secretary are rightly interested in replacing a wild patchwork of standards with coherent common standards and tests that would allow parents to compare their schools with others. The government cannot and should not write those standards. But states that have committed to joining, say, the standards consortium started by the National Governors Association will be favored in the funding competition over states that have not. More consideration will eventually be given to states that develop plans for adopting internationally benchmarked K-through-12 standards that build toward college and career readiness.

Common Core, the anti-reformists, and Connected Mathematics
Those using CMP2 and those using another curriculum scored comparably on standardized mathematics assessments, however, less conservative tests comparing CMP2 and non-CMP2 students indicated that CMP2 students significantly outperformed control students on the Balanced Assessment that reflects mathematical reasoning, problem solving and communication. In this study, it is clear that implementation of the CMP2 curriculum varied greatly across study sites and teachers despite the extensive professional development teachers received prior to implementing the program in their classrooms. However, we suspect that the level of implementation in the classroom, and consequently, teachers’ efficacy, may play a role in the extent to which students might be successful in using CMP2. A second year study will be conducted to investigate this hypothesis and determine more precisely whet her or not t he CMP2 curriculum is superior for students in comparison to alternative mathematics curricula. Student attitudes and achievement are better for those student s in CMP2 classrooms with higher levels of implementation, and consequently, it is expected that teachers implementing CMP2 for a second year would have greater fidelity of implementation as compared to their first year of using the curriculum. Comparing performance of students and teachers in a second year of implementation is a fairer test of the efficacy of the curriculum than the model used in the current study.

More on Common Standards
We're getting a peek at the draft academic standards that a work group is putting together.
Core Knowledge, an advocacy group that calls for giving students deep grounding in content across subjects, has posted a draft copy of the common, multistate standards on its Web site—and it argues that the document completely misses the mark.
The draft document represents the first step in an effort being led by the National Governors Association and the Council of Chief State School Officers to create common academic standards across states. Achieve, the ACT, and the College Board are also working on the project. The first set of standards, which the organizations have said they hoped to have completed by the end of this month, focuses on the standards for college and career readiness in language arts and math. Copies of the draft document had been circulating among some organizations for review, Robert Pondiscio, the communications director at Core Knowledge, wrote on the blog entry. His group decided to post them, because they saw no restrictions on doing so, he said.
The organization's view of the draft document is highly negative. Here's a piece from the online blog entry:
"The draft insists that the voluntary standards be 'coherent' but defines coherence to mean they 'should convey a unified vision of the big ideas and supporting concepts within a discipline and reflect a progression of learning that is meaningful and appropriate.' Framed as a series of benchmarks students must reach 'to be college and career ready,' the draft enumerates standards such as the ability to 'determine what text says explicitly and use evidence within text to infer what is implied by or follows logically from the text.'
"To put this as blandly as possible, this is neither a revelatory insight nor a meaningful standard. Educators hoping for guidance on what particular texts are expected to be taught, or how to get students to reach the bland and obvious standards will be disappointed."
Obviously, Core Knowledge has its own view of what should go into academic standards, and others reviewing the document will have their own. After you've had a look, give me your opinion.
UPDATE from guest blogger Catherine Gewertz: Gene Wilhoit of the CCSSO and Dane Linn of the NGA said it's too early to draw conclusions about the draft, since it lacks the feedback from working groups tasked to review it, and from governors and state chiefs. Once all that feedback is in, a revised draft—with evidence supporting each standard—will be available online, in mid-August, for further public comment. Wilhoit and Linn's overall message? That this draft represents just the first step in a much longer process.
Common Core Standards

Some Interesting Questions
Some interesting questions appear at the EduWonk Blog below. As the common standards are about to be released, please keep these questions in mind.
When people talk about “what (students) know and are able to do” they seem to mean: what they learn in school. Does anyone study the knowledge and skills young people actually have; look at what’s been learned outside school? Have a look at this to get a sense for how much more there is.
Are there to be consequences, ‘high stakes’, for a student not meeting standards? If so, then the standards will be fairly low, won’t they? The politics of this public institution mean that K-12 realistically can’t deny success to more than a small proportion of students. (Probably this explains the interest now in ‘benchmarking’, which lets everyone see performance compared to others while imposing no sanction.)
Is there a concept of achievement, then, above the standards? Surely high achievement (as in the STEM areas) must be important, especially for the country’s economic success. Where and how is that assessed? Who works to encourage high achievement?
Beyond a ‘basic’ level is it essential that all students achieve the same thing? Why are standards set in terms of exit from high school rather than in terms of entrance into what a young person wants to do next? Would it be OK to differentiate ‘achievement’ for different groups of students; for individual students? Might that diversification better serve to produce the breadth of accomplishment the country needs?
Is it really important for all students to master algebra? What fraction of the occupations actually require knowledge of Algebra II? Might it be better to try to get students to understand something of statistics: probability, risk, rates, proportions and such?
Do schools achieve — or is it only students who achieve? Is the students’ achievement the school’s achievement? Or is Professor Raudenbush correct that one cannot properly use measures of student proficiency to draw conclusions about school performance?
Should achievement be treated as something adults do? That seems implied when we talk of education being ‘delivered’. But in the end who does determine what a student knows and is able to do?

NJDOE Math Task Force Update
Nearly two months after the last NJDOE math task force meeting, NJDOE has found the time to issue the following statement:
TO: Members of the Math Standards Task Force
FROM: Willa Spicer, Deputy Commissioner & Sandra M. Alberti, Director, Office of Math and Science Education
DATE: July 10, 2009
RE: Update on New Jersey Math Standards
It has been well over a month since the last time we all formally gathered as a task force. Certainly, a lot has happened during that time. Attached please find a document that captures the products of our discussions and work together as a task force as well as a brief update regarding the common core initiative. Our intention in bringing this group together was to address many of the issues being debated regarding the math standards. We are very pleased with the commitment of task force members to grapple with these issues as a group. We believe that this experience was valuable to our staff as well as to many of the participants.
In moving forward, we will first consider the documents that come from the common core initiative. We look forward to sharing the drafts with you as well as larger stakeholder groups throughout the state. Our collective work that is represented in this packet, as well as the resources that each of you brought to this work, will certainly help to inform this process. Please accept our sincere gratitude and appreciation for your dedication and commitment to mathematics education in New Jersey. We look forward to more opportunities to work together in the future as we continue our work.
Notice, in particular, the words "we will first consider the documents that come from the common core initiative". I will share some insight about the common core initiative in the next post. Full memo from the NJDOE.

NJDOE Math Task Force Dies without DOE Action
Now that the Math Standards Task Force has completed its work, a number of us want to address the issue of what will happen next. For the Department of Education to develop a set of math standards that will provide teachers, schools, and districts with the guidance that they need to enable our students to achieve high expectations in mathematics, it is critical that the next steps, following the efforts of the Department’s Task Force, build on the good work already done and involve people who are best able to craft the standards New Jersey deserves.
There are many people who can examine and critique individual indicators in the standards, including many of the members of the Task Force. But only those with a more intimate knowledge of the curriculum, such as math supervisors and curriculum specialists, are able to see the standards as a whole, so that an individual indicator is not only analyzed in itself, but also in regard to how it fits in the K-12 flow within its standard and how it fits it with indicators in other standards at its and nearby grade levels. Those are the people who should be called upon to provide advice on the content of the standards.
Writing standards requires a team whose members:
ª have a deep understanding of mathematics and of the PreK-12 mathematics curriculum
ª understand the curricular consequences of what might appear to be a modest change of language
ª can write concisely and clearly
ª understand assessment and have experience with a wide range of types of questions including multiple-choice and extended response
ª have knowledge of a wide variety of curricula in order to ensure that appropriate, high-quality instructional materials are available
ª have knowledge of the psychology of learning mathematics so that content is developmentally appropriate.
Even those who have experience with the content cannot necessarily translate their recommendations into the language of standards. The people in New Jersey who have the greatest experience and expertise in doing that are Janet Caldwell, Warren Crown, Bob Riehs, Joe Rosenstein, and Bill Smith (Crown and Smith are now retired and may therefore not be available). In addition to and because of their qualifications, they have the trust of their colleagues across the state. They should be key players in the further development of math standards which are both credible to the field and of the highest quality.

Big News at Rowan
With the stroke of a pen, Gov. Jon S. Corzine Thursday changed the landscape of higher education and health care in South Jersey. Through an executive reorganization plan submitted by the governor to the state Legislature on Thursday, Corzine requested the creation of a four-year allopathic medical school on Broadway in Camden that would combine the resources of Cooper University Hospital and Rowan University. The result would be the fourth medical school in New Jersey, and the only one not to be affiliated with the University of Medicine and Dentistry of New Jersey.

The Structure of Educational Revolutions
Mathematics education, particularly in the United States , has been a subject of controversy for some 40 years now since the time of the New Math in the 1960s. Indeed, the New Math has been called the first of three "revolutions" in mathematics education [2], the other two being the back-to-basics reaction to the New Math and the changes wrought by the NCTM Standards (hereafter the Standards) [10]. The first two of these, however, whatever you may think of either, were not revolutions in the Kuhnian sense and the last, whatever the long term impact of the Standards, proposed only a modernization of school mathematics education rather than anything revolutionary.
One thing the Standards did do, however, was to spark the so-called Math Wars which for nearly 20 years now have pitted mainly research mathematicians but also some parents, business groups and teachers and others (Traditional Math Warriors - TMWs) against mainly mathematics educators but with significant support from some parents, teachers and others (Reform Math Warriors - RMWs) [5, 12]. At times these wars have led to acrimonious exchanges between the two sides; at other times the exchanges have been more genteel. There have even been recent attempts at truces [3] and fudges [9]. But an end to the Math Wars is not in sight nor, I believe, should it be because the essential issues are too important and the essential positions of the two sides are so far from each other that what is needed is victory for one side, not a pale compromise that, in the long run, would not be good for anyone.
Calculator technology has been the catalyst for almost all the disputation in the Math Wars. Since this technology almost wholly diminishes the practical value of PPA, it is essential to answer the question above about whether these algorithms are the best way, even an effective way to prepare students for further study of mathematics. In one sense, the answer to this question is clearly, yes, since there is no alternative to these algorithms that has ever been tried in schools anywhere.
It is only reasonable to conclude this paper by asking the question: If the computer revolution presages a paradigm shift in elementary school mathematics education, will there also be paradigm shifts in other aspects of mathematics education?

Abolish Paper & Pencil Arithmetic
Let's Abolish Pencil-and-Paper Arithmetic by Anthony Ralston (Imperial College, London). The paper appeared in Volume 18, Number 2, pp. 173-194 (1999) of the Journal of Computers in Mathematics and Science Teaching. (The anti-reformists will love this article!) The article proposes that paper-and-pencil arithmetic no longer be taught in elementary school and that it be replaced by a curriculum which emphasizes mental arithmetic much more than at present and in which calculators are used for instructional purposes in all grades including kindergarten. The article analyzes and refutes the arguments made by "back-to-basics" proponents against the use of calculators and for traditional instruction in the algorithms of pencil-and-paper arithmetic. The value of mental arithmetic in achieving all the aims - and more - of the traditional curriculum is argued. Also considered is the outline of an elementary school mathematics curriculum without pencil-and-paper arithmetic. As well, the impact of such a curriculum on secondary school and college mathematics is discussed. Finally, the barriers to achieving what the article advocates are assessed.

On the shortage of scientists and engineers
While the U.S. is middling in ranks in math and science assessments, the differences among countries in terms of scores are often quite small. The most extreme occurrence of this phenomenon was in the eighth-grade science assessment for the 1995 TIMSS (Third International Mathematics and Science Study). American students got 58% of the items correct, compared to 56% for the international average. This ranked them 19th among the 49 participating nations. Middling performance, no? Had they gotten a mere 5% more correct answers, they would have ranked fifth, and had they gotten 5% fewer correct, they'd have slumped to 30th.
1. The U.S. suffers serious shortfalls or shortages of scientists and engineers, and this bodes ill for both creativity and international competitiveness.
RESPONSE: There is no shortage. Several RAND Corporation studies found surpluses. There might be shortages in some new fields or fields growing explosively, but not overall.
2. The number of newly educated scientists and engineers is insufficient to fulfill employer needs. Thus the need to hire from overseas.
RESPONSE: There are substantially more scientists and engineers graduating from U.S. universities than can find attractive career openings in S & E fields. Indeed, the S & E opportunities seem unattractive to many holders of S & E degrees. "Into the Eye of the Storm" (no doubt a pot shot at the National Academies), a paper by Lindsay Lowell of Georgetown University and Harold Salzman of the Urban Institute, found roughly three S & E graduates for every new S & E job (not counting openings created by retirements). They also found that two years after graduation from S & E programs, 20% of the grads with bachelor's degrees were in school but not in S & E programs and 45% were in the work force but not in S & E jobs. The attrition rate for that time period for those with master's degrees was about 38%. One can only imagine how critics would howl if education lost 65% of its work force in just two years!
Nor are fewer students following S & E paths in universities. From 1977 to 2002, the number of citizens and permanent residents earning bachelor's degrees in S & E grew from about 300,000 to about 400,000, those earning master's degrees increased from about 60,000 to about 70,000, and those earning doctorates held steady at about 20,000.
Other studies have concluded that the decline in the pool of citizens and permanent residents with S & E credentials may reflect a weakening demand, a comparative decline in S & E wages, and market signals to students about low relative wages in S & E. I'm not sure exactly what the "market signals" are, but real wages for S & E workers have declined over a 20-year period. And students can see older scientists spending more time writing grant applications, getting fewer of them funded, and having a tougher time getting tenure. They can see the post-doc headed for what science writer Dan Greenberg calls the newest title: post-doc emeritus. And students, not surprisingly, head to greener fields.
Finally, there is some evidence that the nature of the engineering profession has become less appealing. Lowell and Salzman observe that projects today are often larger team efforts that require more coordination and management. In their interviews, engineers often commented that the field was not as challenging as it once was because it contains less "real" engineering.
