Happy Birthday Darwin!
He has changed our lives and world outlook forever, and made medical science more inductive, integrated with survival, and practical than it has ever been. Not that all doctors have grasped his message; far from it: there is still a lot of catching up to do. But each of us, on our own, can improve our thinking about diet and health based on the theory of evolution.
We celebrated his birthday last year, and posted a link to a biographical sketch of Mr. Darwin.

Discovering the Principles and Effects of the Discovering Math Series
In reading Robert Pondiscio’s “Suing Over Curriculum” (February 5, 2010), I was amused to find mention of a math text that I find generally flawed and illogical: Discovering Math. It is a text used locally, too, so I’ve had the stress of having to tutor some students who are subjected to the text’s cognitive torture. I feel sorry for them.
Yes, of course, the texts have some good points, they do give some good or decent explanations of some things and there are a few good diagrams in them; but all texts must say 1 + 1 = 2, or the authors and publishers will be laughed out of society. The texts are so full of irrelevant pictures, it is hard to concentrate on the reading and the exercises. And the exercise sets do not at all allow students to learn, practice, and become proficient at concepts and methods. Very few students, I believe, could figure out what to do in some of the exercises, even if they had had practice in the basic concept being drilled.
In an article about a court case involving the “Discovering” series, “Seattle Schools’ ‘Discovering Math’ curriculum risks a generation of students” (May 29, 2009 at 2:53 PM) by Cliff Mass (Professor of Atmospheric Sciences at the University of Washington), the Seattle Times said:
ON May 6, the Seattle School Board voted on the purchase of high-school math textbooks, and the results were both disappointing and tragic.
In a 4-3 vote, the board adopted the Discovering Math series: “discovery-based” math texts that were found to be mathematically unsound by mathematicians working for the state Board of Education. As noted by Professor Jack Lee of the University of Washington, “definitions, computational algorithms, and formulas seem to be stated vaguely when they are stated at all.”
These books are “discovery-based” or “reform” math texts in which discussion, group projects, manipulation of objects, use of calculators and inefficient “exploration” replace students acquiring of key skills, solving real-world problems and developing a strong mathematical foundation. At the core of this math series is the theory that unless students “discover” math facts themselves, they are unable to master and apply them effectively.
The damage from “Discovering Math” is multiplied by Seattle’s previous selections of similarly weak “discovery” curricula in elementary (”Everyday Math”) and middle school (CMP2). During the roughly 10 years the Seattle Public Schools has used discovery-based math texts, the achievement gap for disadvantaged students has widened.

In “Looking at the decision” (seattle math group Blog, Friday, February 5, 2010, 12:06 AM), Martha McLaren writes:
Judge Julie Spector today announced her finding of “arbitrary and capricious” in the Seattle School Board’s May 6 vote to adopt the Discovering Math series of high school texts despite insufficient evidence of the series’ effectiveness.
Judge Spector’s decision states, “The court finds, based upon a review of the entire administrative record, that there is insufficient evidence for any reasonable Board member to approve the selection of the Discovering series.”
The text itself, and the false theory behind it, should have been declared “arbitrary and capricious” and based on “insufficient evidence.”
The effect of the texts are addressed above: cognitive failure, an inability to do math, and an inability to grasp the essentials of math. The principles behind the text are basically those of John Dewey: truth is a social construct; the “consensus” reigns supreme; “learning” is just verbal behavior; there are no objective absolutes; cognitive hierarchy and context don’t really matter.
Update (9:00 PM): On a related note, check out the site Mathematically Correct. They say about their site:
This web site is devoted to the concerns raised by parents and scientists about the invasion of our schools by the New-New Math and the need to restore basic skills to math education.
Mathematics achievement in America is far below what we would like it to be. Recent “reform” efforts only aggravate the problem. As a result, our children have less and less exposure to rigorous, content-rich mathematics .
The advocates of the new, fuzzy math have practiced their rhetoric well. They speak of higher-order thinking, conceptual understanding and solving problems, but they neglect the systematic mastery of the fundamental building blocks necessary for success in any of these areas. Their focus is on things like calculators, blocks, guesswork, and group activities and they shun things like algorithms and repeated practice. The new programs are shy on fundamentals and they also lack the mathematical depth and rigor that promotes greater achievement.
Concerned parents are in a state of dismay and have begun efforts to restore content, rigor, and genuinely high expectations to mathematics education. This site provides relevant background and information for parents, teachers, board members and the public from around the country.
A Need For Grammar
Students need to learn grammar. Seems like it is not taught anymore. Knowing grammar, being able to parse a sentence, knowing how to diagram a sentence, are extremely valuable in math and science, as well as in reading and writing. I have to help students with this all the time. It makes a difference between understanding, or not understanding; between passing and failing. Contact me if you want some math/SAT/ACT tutoring that is head and shoulders above the rest!

Math & Memorization 2
Of course, there are other reasons to memorize things, besides those I mentioned yesterday, and there are other things in math that should also be memorized, but those reasons and those things are for paying clients only, i.e., people who are willing to make a fair trade of value for value, who want a win-win relationship. I’d love to help improve your or your child’s thinking skills!
Update (10:20 PM): In an episode of “Sport Science,” the NFL quarterback Drew Brees shows us how accurate we can be. (HT: Dr. Diana H) What Mr. Brees is doing is a physical activity, yes, but it is dependent on neural activity, cognitive training and cognitive consistency.

Math & Memorization
In today’s students, I really see a lack of ability to understand math because of (for one thing) a lack of retention of math because of, in turn, a lack of memorization. Memorization is anathema to the philosophically corrupt modern intellectual, to the modern theorist of education. It, along with drill, was attacked vigorously when I was getting my Texas Teacher Credentials, and still is, as such attack is implied by a broader perspective on mind and thought: the perspective of John Dewey. (Ultimately, Dewey and the Deweyans believe, consensus creates reality, nothing abides, so why remember anything when it will become outdated? Dewey even claimed that Aristotle’s logic worked so long, it had to be wrong. So A is no longer A: things do not have a nature or identity; their apparent nature changes; things are what we as a group want them to be.)
I’d highly recommend students memorize and be drilled in, at the least, their multiplication facts, working (adding, subtracting, multiplying, dividing) with fractions, and the perfect squares. Students should memorize definitions and methods, as well. These facts are universal and timeless. A is A.
If knowledge is not ingrained and remembered, then it is not there to utilize and build on. What’s more, memorization and understanding reinforce each other.
Let’s not sell our children out; let’s not be comprachicos distorting their minds and souls.

Getting the Idiom Wrong, And More
In an email from a friend, I received the following list of butchered idioms, historical references, names, and sayings (sometimes the correct word, name or phrase is given after a dash or in parentheses):
In my browsings on the Web (long story) I came across this. (Long story, it’s an offshoot from http://www.livejournal.com/~bcampbell/ if you’re that interested.) I reproduce it here as it appears on the page.

TAKS Practice Material
On the Internet there is a plethora of practice material for the math portion (and science, reading, etc.) of the TAKS test. The Texas Education Agency, TEA, has made available pdf files of some recent tests and also has a number of tests archived. This material would be good for preparing for the TAKS test and for practicing algebra and geometry.
Pearson has made available some pdf files of study guides and has some online, interactive study guides. (If those links do not work, start on the TAKS Study Guides page, then click on “Interactive Study Guides,” or click on “Printed Study Guides” followed by “Study Guide PDFs.”)
