Math Education Reform and Critical Thinking


When I was a kid, my life was mathematics.  When I was little, my mom would hand me sheets of addition and subtraction problems that did not involve carrying or borrowing, and I would fill them out for her, and she would give me more.  That’s my earliest memory.  Second earliest is the procession for President Kennedy after his death.  Third earliest might be my Dad changing my brother’s diaper.  My mother once said, “You must have remembered it because of uniqueness.”

Anyway, when I was a kid, before I went into first grade, my mom taught me multiplication and division.  My Dad taught me some heuristic rules around percentages.

So when I came into first grade at age six, I was shocked that no one else could do math.  I was good enough with math and reading that the special education teacher took note of me, and helped give me my unusual education 1967-1969.  Though I was in a normal classroom, I was a “group of one.”  I had my own special reading and math books.  The teachers pushed a variety of enrichment materials to me, but it was like subpar homeschooling.  I was on my own, and no one would correct my work.  For a little kid, I was pretty motivated, but it would have helped a lot to have more adult interaction.

SRA helped on the reading side, and there were later SRA attempts at math though I don’t think that did much.

In third grade, they gave me a programmed instruction curriculum in math, in addition to the ordinary class.  At some points, I acted as a tutor to other students.  The programmed instruction was modeled after the “new math” fad.  I could get it, but at the time, I realized that I was so different from my peers, that I knew that if I could get it, that did not mean that others my age could get it.

Then in fourth grade, they mainstreamed me.  I spent time playing around with how to do square and cube roots by hand.  Tedious, but not that hard to do.

In fifth grade, my Father brought me an algebra book that used programmed instruction.  I puzzled over it, and didn’t get it until I talked to an older friend about it who told that “x’ is a number that we do not know, but are trying to calculate.

There’s more to this story, but I will drop it, lest I bore you…

What I experienced as a child affected me.  I could see the abstraction of math while young, and it amazed me.  But now look through my eyes as I find out that I am unusual.  There is a normal track for math, and a normal way to teach it.  As I tried to tutor my classmates, I realized math was not intuitive for almost everyone else as it was for me.

I became a good math tutor.  Parents would hire me , and ask me what my rates were.  I don’t know how I thought of this, but I said, “Five dollars per sitting.  A sitting could be five minutes or two hours. If I lose their attention span the sitting ends.”  That motivated the parents to motivate the kid.  After one short sitting, future sittings got longer.

As an adult, I married a math teacher.  She admits that I am the better with math, and that I often come up with creative ways to teach concepts that she could not.  She is still quite good with teaching math such that all of our biological and adopted children made progress in their percentile scores in math and other topics as they grew.

I think that I know math, and how to teach math.  I have done it while young, and older with my older children.  I have never taken a course in education, and thus my views of pedagogy have never been sabotaged by what is taught in most colleges regarding teaching children.

Some may think this assessment too harsh, but remember, we had the “New Math” in the Sixties.  It was a disaster.  For me, a math prodigy, thinking about math through the lens of set theory, it was challenging and interesting.  To most students, it was deadening.

So now we have the evil “Common Core Math Standards.” [CCMS] When I was a kid we joked about Communist plots to destroy America.  Well, I think the Communists are pretty weak in general — they don’t understand the nature of man.  But here we are trying to make kids try to make adult judgments regarding math.  That’s just plain stupid, because it doesn’t get the way children develop.

The Holy Grail of Critical Thinking

I don’t think critical thinking can be taught.  If you are smart enough, you will think critically. If not, no.

I say this as one where my wife and I have homeschooled our eight children for 18 years, and as my children get older they disagree with us to varying degrees.  We taught them well.  Sadly, some disagree with our premises.  But, they are all smart and the seven that have gone through standardized testing have all shown significant progress, moving 25% or more in the percentile rankings from elementary school to high school.  My wife teaches very well, and I support her. Please also note that five of the children were adopted, and the same effects happened with them.

But the CCMS flips things on its head.  Children need to learn facts.  They can absorb facts because they are easy for the young  to absorb.  Drill on math facts is a very good thing because it eliminates a hurdle to learning more in math.  Once you know the basics, the mind is capable of absorbing more abstract reasoning.

It is the opposite of what the experts say.  Math should focus on the concrete with young children, and as they get wiser, on to things that are more abstract.  They should not begin with abstraction, and try to move to the concrete.

Think about it for a moment: would you rather hire a guy who understood the basics of your business, or hire a guy who had a theory about your business, but did not understand the basics?  You would hire the former if you were smart.

Understanding the basics is important, and sadly, we have gotten away from it in the last 60+ years in math.  We did much better in the past, and we paid teachers less in real terms back then.  The colleges that teach teachers should be dismantled, and teacher accreditation should be eliminated, because there is no clear value created by accreditation.

We need education to be more like home schools, where teachers train students for many years in elementary grades K-8, where tutoring plays a large role. Understanding the student, and consistent mentoring makes a far brighter student.  Eliminating credentialing would being in brighter, more motivated teachers that ignore the idiocy to the teaching colleges.

Now maybe there is a home and private-schooling cabal, pushing CCMS in an  effort to destroy the public schools, or at minimum, assure that those who go to public schools will be peons to those who don’t go there.  I really doubt that, because those who don’t send their kids to public schools are more upright than those that don’t.  They are putting forth extra effort for their kids, versus people who don’t care.

Practical Advice

I live in Howard County, one of the richest counties in America.  Unique to Maryland, the counties are the school districts.  We homeschool in a county that is one of the best around.  We are evangelical Christians, but most homeschoolers here are secular. Why?

The school districts adopt a variety of dumb ideas like CCMS that hinder reading and math.  If I could vote to eliminate the public schools I would do so not out of ideology, but raw incompetence.

Most parents that we interact with are either hiring a tutor in math, or doing it themselves.  If that is the case, why not homeschool? It’s a lot easier than it looks, and it doesn’t take a lot of effort to outperform the public schools.

The main reason is the two-earner household.  Most could tighten their belts, and have one parent stay at home to teach the kids.  The second trouble is child control/discipline — my comment is if you are firm with them as parents were prior to 1950, you should have no problem, but consult your local statutes to figure what you have to hide from.

With CCMS many families will have to do one of the following:

  1. Tutor their children in math
  2. Pay someone to tutor their children in math
  3. Homeschool
  4. Start a war against those that set the public educational standards


Children are not capable of absorbing abstraction.  Every real parent knows that.  Fight the educated idiots who are trying to ruin math education with their misbegotten theories that do not understand math or kids.

Updated on

David J. Merkel, CFA, FSA — 2010-present, I am working on setting up my own equity asset management shop, tentatively called Aleph Investments. It is possible that I might do a joint venture with someone else if we can do more together than separately. From 2008-2010, I was the Chief Economist and Director of Research of Finacorp Securities. I did a many things for Finacorp, mainly research and analysis on a wide variety of fixed income and equity securities, and trading strategies. Until 2007, I was a senior investment analyst at Hovde Capital, responsible for analysis and valuation of investment opportunities for the FIP funds, particularly of companies in the insurance industry. I also managed the internal profit sharing and charitable endowment monies of the firm. From 2003-2007, I was a leading commentator at the investment website Back in 2003, after several years of correspondence, James Cramer invited me to write for the site, and I wrote for RealMoney on equity and bond portfolio management, macroeconomics, derivatives, quantitative strategies, insurance issues, corporate governance, etc. My specialty is looking at the interlinkages in the markets in order to understand individual markets better. I no longer contribute to RealMoney; I scaled it back because my work duties have gotten larger, and I began this blog to develop a distinct voice with a wider distribution. After three-plus year of operation, I believe I have achieved that. Prior to joining Hovde in 2003, I managed corporate bonds for Dwight Asset Management. In 1998, I joined the Mount Washington Investment Group as the Mortgage Bond and Asset Liability manager after working with Provident Mutual, AIG and Pacific Standard Life. My background as a life actuary has given me a different perspective on investing. How do you earn money without taking undue risk? How do you convey ideas about investing while showing a proper level of uncertainty on the likelihood of success? How do the various markets fit together, telling us us a broader story than any single piece? These are the themes that I will deal with in this blog. I hold bachelor’s and master’s degrees from Johns Hopkins University. In my spare time, I take care of our eight children with my wonderful wife Ruth.
