Interview with Arne Duncan
Meet Arne Duncan on YouTube

Thank you readers for having patience waiting for this blog entry. I have had an interesting time learning about Secretary of Education Arne (pronounced Ar-nee) Duncan and a challenging time processing it all.

The Lowdown

  1. Duncan grew up in Chicago & played basketball through college
  2. His dad was a professor & mom ran a tutoring center
  3. Duncan graduated from Harvard in 1987 with a degree in sociology
  4. Duncan & Obama have known each other for over 20 years
  5. Duncan’s 2 kids attend public school
  6. Prior to his current position, Duncan was CEO of Chicago Public Schools
  7. Many improvements to schools & teachers, as well as remarkable test score gains were made during his tenure as CEO
  8. Duncan’s policies on education are primarily what is shaping the direction of education today
  9. Duncan says preparing kids for success is and “economic imperative.”
  10. Duncan believes in a punishment & reward system for teachers

As many of you are aware, once a person steps into the political limelight, the general public tears them apart, criticizes their actions and opinions and are quick to judge. The main reason for this of course is that it’s a political game and everybody is scrambling for attention and power.

There is definitely some criticism out there. Some postulate that Duncan’s success improving the statistics of Chicago’s education system is just another Rod Paige scandal (Paige was appointed Secretary of Education by former President G.W. Bush and vacated the office after it was discovered he had taken unethical action to get his results). I don’t buy into unfounded assertions like this.

Some too, criticize Duncan’s exuberant support of Charter Schools. What will happen to our public schools if all the economically advantaged choose private, alternative and charter schools? Duncan says of charter schools that the good ones are part of the solution and the bad ones are part of the problem. He believes that all families should have choices for where there kids are educated. Right now it is limited to those with economic advantage. Duncan maintains that education is a civil rights issue. I would love to see him expand on this statement.

I appreciate that the education goals of the Obama Administration including Secretary Duncan, are focused on bringing low-income kids up out of poverty through education though I’m not convinced it would be a priority if not for our failing economy. It seems like a good plan for the economy, but is it the best way forward for education? I do believe, given Duncan’s upbringing in his mom’s tutoring center in Chicago serving under-privileged kids and his statement on ED.gov that education is also a “moral obligation,” as well as a “civil rights issue,” that Duncan really has genuinely positive intentions, despite his recent remarks about Hurricane Katrina being the best thing that happened to the education system in New Orleans. I know it is an easy thing to jump on and it was a political blunder on Duncan’s part but to me, it is obvious that he is trying to focus on the positive, something we all need to do just to get by sometimes. I highly doubt that Duncan was glad that Hurricane Katrina devastated New Orleans.

I am absolutely against a punishment and reward system for teachers. Duncan says we need to reward good teachers with financial incentives and get rid of teachers who are ineffective. His saving grace for me is that he says we need to get rid of them after we try to help them and if then they still are ineffective. This is another one of those issues that may sound great in theory, but in practice it is going to be a giant, painful belly flop. Being an effective teacher is a skill that is developed over many, many years. We already have a teacher pay scale that increases with time and experience. Given the average teacher salary, we all know that teacher’s aren’t in it for the money. What will be the system that decides which teachers get merit pay and based on what results? Most of us have figured out by now that judging a student based on a single, multiple choice test can have misleading results to say the least. The most horrendous consequence of all is that the punishment/reward system will scare off new teachers and (possibly) attract teachers who want to get in on the merit pay. Speaking from experience, new teachers already have such unrealistic expectations placed on them and for the most part they are going to naturally be the ones who don’t have lots of success with their students in the first couple of years because they have yet to find their path and to gain the experience they need. Fear of inadequacy and the possibility of having to make a career change mid-life if someone deems you unworthy of being a teacher will drive off teacher candidates.

What does need to happen instead is high quality, useful, meaningful professional development for teachers at differing levels of the trade. Teachers, especially early career ones, are not given sufficient time for collaboration, reflection and learning new content and skills. Early career teachers should have more time for professional development, working with mentor teachers and co-teaching experiences. Late career teachers should be sharing their knowledge and skills through mentoring, conducting research and publishing. School Districts should provide high quality substitute teachers who are familiar with the school to give classroom teachers the time they need to learn and improve. The money for the substitute teachers should come from a tiny portion of the $4 billion dollars from the federal government for education without compromising state rights in education.

For me, watching Secretary Duncan is a wait and see game.

Article: Hands-on, Minds-on, authentic learning in math

What I read
http://wheresthemathbellingham.blogspot.com/2010/02/penn-state-math-professors-oppose.html#comment-form

http://ies.ed.gov/ncee/pubs/20094052/pdf/20094052.pdf

There are three issues to address: How Investigations is taught, the meaning of constructing ones own learning, and being mindful of how to move forward in a solutions-oriented way. I hope that members of your group can run some focus groups and invite members of the school community to participate.

Let me begin by saying that I am neither for nor against Investigations as the best math curriculum to teach. However, it is important to understand how Investigations works. Its authors intended it to be a resource as well as a textbook for teachers so they could get professional development in along with preparing for class. This is important to note, because many elementary school teachers find math to be their most challenging subject. In theory this is a great idea, but to teach Investigations well, you have to read the entire book unit you will be teaching, figure out the main concepts and then adapt it to your methods. Then, as with any subject textbook, supplemental materials are a must. Who has the time?! The problem with Investigations as I see it, is the practice ends up being very different from the theory.

My second item of contention is the misuse and misunderstanding of what it means to construct ones own knowledge. In the open letter from the PSU professors you reference in your blog, it states: “This program is based on the highly controversial idea that one bypass basic techniques when teaching mathematics, that the students will themselves discover mathematical truth, while the teacher only plays the role of a facilitator.” Well, yes, it is a highly controversial idea because educators understand it in different ways. We as an education community must come up with a “standard” definition or we will continually argue about issues we later discover we actually agree upon. To me, constructing knowledge is based on the idea that when the brain receives new input, it attempts to understand it by processing it against all the other information it already has. We sometimes call these “making connections.” A teacher, when guiding a classroom of learners will activate background knowledge, create an environment where students do activities, journal, discuss, compare, reflect and defend. In such an environment though the teacher leads them all the way up to the new concept, the “ah-ha” moment will be something they own. A true success that builds self-confidence.

Finally, I have read the study you refer to and Investigations falls neither at the top nor at the bottom of the program studies (Please see comment below). This does nothing to convince me that it is a poor or unreasonable math program as you infer. Furthermore, the study was done only with 1st graders. In the Investigations program, a strong conceptual foundation is built first and in later grades more efficient methods are learned. It doesn’t surprise me that, based on one test to assess their learning, that the first graders learning Investigations didn’t score at the top. In my opinion, the open-minded and solutions-oriented way to move forward, is to work on finding studies, facts, etc. on a program that is worthwhile. Instead of urging the school district to abandon what is already in place, why don’t you take advantage of this opportunity to get a professional research organization in your schools and have them conduct studies. Any of you who are teachers have most likely had training like I did on research methods and you could, working together, conduct your own study so long as its results are uncompromised. I think it’s time that we all step up and take more action in regards to our local schools as well as our school districts and school boards. I sure don’t see anyone else out there who is more capable of improving our schools than you, teachers, parents, staff, principals and concerned citizens. So, my advice, find a better alternative and present it to your school board and the mayor and your school district. Do the work for them and compare the curriculum, show the data and they will have no choice.

All the best, -Tia-

What I read:
http://mathforum.org/

The Math Forum is a web site from Drexel University in Pennsylvania. Their slogan is “People Learning Math Together.” This site is intended for all people interested in math to come together to enrich and support the learning, sharing, teaching and communication of math topics. My immediate as well as overall impression of the site was that it is extremely professional as well as warm and inviting. I appreciate that very much since many people (myself included) can be scared off from a site if it seems to belong to people who know more than I. This site is welcoming to students, teachers, parents, researchers and interested citizens. So go forth fearlessly!

The LowDown

  1. Fun games, puzzles, math problems & tutoring for students
  2. Resources, homework help, math library & answers questions for parents
  3. Lesson plans by grade level, discussion forums, education policy topics & professional development for teachers
  4. Weekly newsletter that includes sites to visit, key issues in math education and tips
  5. 6-week online continuing education courses on multiple topics for only $149 (1.5 CEU certificate)
  6. Ask Dr. Math forum and books
  7. 2010 Math Games your class can participate in (Make 1-100 using only #’s 2010 using operations)
  8. Free 21 day trial class membership for Problem of the Week (PoW)- individual available too
  9. Links to interactive math tools
  10. Active, interesting, focused and timely discussion forum

I would recommend reading the About page first for a good overview. There is an easy to find search button and some of the information is in more than one place for ease of use. The web site is very fluid with two exceptions. First, the site doesn’t have a back button, you have to use your browser’s. Second, the discussion forums don’t seem to take advantage of using threads to post. For example, I found an interesting post but had to search back several pages to find the original one that it was responding to. I love that the site is current. Discussions posts were from today. Pictures of staff were fun to look at, they seem very friendly. The advertisements on the site were math related only which is refreshing. If you are thinking of taking an online workshop, check out the description first. Some of them require you to be a member of the PoW at the class level which means during the class you either need to have just ordered the free trial or you need to spend $119 more. If you are a current teacher however, this seems like a worthwhile expenditure because you and 36 students get access to the PoW archives.

I signed up for Math Forum’s newsletter today and was particularly enticed by the online workshop possibilities given that the cost is extremely affordable compared to other online classes I’ve seen, as well as the discussion forums which I am going to have to go back to and spend an hour or two just reading them. Compared to the A to Z Teacher Forum and other such online teacher discussion boards, this one seemed focused and interesting. Posts were on topic (math) and some shared very interesting information such as the history of math and other out of the ordinary math topics as well as the typical ones. If you are looking for an answer to your math question or feedback on your lessons or ideas, the Math Forum seems like an excellent place to exchange those ideas or just ask Dr. Math. I’ll have to think of a good question for her or him or…actually there are over 300 volunteers who answer these questions. Questions can come from any age learner and will be sent to a Dr. Math who can (hopefully) answer your question.

So, click on Math Forum now or bookmark it for later. You can also find the link to the right of this blog in the Mathematics Links box.

NEXT: Secretary of Education Arne Duncan

Today I read a book entitled Math Lessons for Elementary Grades. Its author is Dorothy Harrer and it is published by the Association of Waldorf Schools of North America (AWSNA). It’s a short little book of 131 pages. After an excerpt from Rudolph Steiner (The founder of Waldorf education) and an introductory chapter on teaching arithmetic in general, the remaining chapters and the bulk of the book are dedicated to sharing mathematics lessons from grades one through six.

I am adding a new section to my posts called The Lowdown. This section will be just the highlights or just a summary of the blog given in a list from 1-10. Given my blog entries tend to be verbose (though clear I hope!), I wanted to give you, the reader, an option of just getting a quick snapshot for when you don’t have the time to read a whole entry. Say no more here it is:

The Lowdown

  1. Cheap ($14), worthwhile book, for stories, games, lesson plans for grades 1-6
  2. Children weak in math should have PE/movement time for counting & stepping forward & backward
  3. Phrasing problems the right way is essential-say what you have or want, not what you add or take away
  4. Teach addition, subtraction, multiplication and division simultaneously & then practice a lot
  5. Reach younger children through their imagination by using pictures & stories
  6. Use rhythmic activities and dramatic acting to improve and solidify memory & memorization
  7. Introduce ideas to older children by giving them sets of numbers (whole, fraction, decimal, etc.) & let them figure out the pattern, then have them identify the rules
  8. Older children like to play and hear stories too
  9. Lessons should begin with an activity, move into counting (or other math) and then end with writing
  10. A mill is 1/10 of a cent

First let me say that I absolutely want to re-read this book in order to actually do the problems presented in the book. Being a teacher, I know how important it is to actually do the problems you are presenting to your students so you can see what sorts of questions or problems they might have. It is also wonderful to challenge yourself to do every problem more than one way (like hopefully you ask of your students).

General ideas to keep in mind
Children who are weak in math should have extra time to do movement exercises that include counting forward and backwards, moving a staff around the body, walking and running. Why?

“What lies at the root of arithmetic is consciously willed movement, the sense of movement (and it) will have the effect of bringing the child’s arithmetical powers to life.”

When phrasing math problems, do say  ”I have 7, how much must I take away to get 3?” Don’t say “What remains over if I take 4 from 7? In the first example you are dealing with concrete things: what you have and what you need to get. This sort of thinking is easier for children to access. In the second example, the phrasing is abstract, making the problem more challenging to access.

Since multiplication is just repeated addition, they could and should be taught together. Not only that, but the the author claims it is much more efficient to teach all four processes at the same time without lingering too long over explanations and then just move into practicing all four. In this way I suppose, children are more likely to see the relationships between numbers and their functions, a skill which tends to be lacking for many students.

Children, especially 6-7 year olds are quite imaginative and active. As a teacher, you should reach the child using these same ideas. Use pictorial lessons for helping students access their thinking powers and rhythmic activity for memory. Dramatic acting out also helps set things to memory.

1st grade- Lessons include rhymes for numbers, shapes, a Gnomes and Jewels math story and pictorial representations of the four processes (+,-,x,/) using gnomes.
2nd grade- Story to introduce factors, active arithmetic for learning about even and odd, fill in the blank stories with math problems, a game where kids act out characters such as “Treasure Hunter,” stories for various times tables, skip counting rhythm exercises and pattern making.
3rd grade- Story about math in our lives, finding patterns in number tables, practice in written and oral skip counting, measurement stories discussing liquid and dry measurements, weights and time.
4th grade- Story introducing carrying and borrowing, traditional algorithms, area measurements, fraction tree, four processes with fractions, expanding fractions, active studies in squares, ten as a helper number, order of operations.
5th grade- History of numbers, story Pythagoras,  square, triangular and oblong numbers, chart of equivalent fractions, extend and reduce fractions, “secret” divisor, manipulating numbers when dividing and multiplying fractions, decimal practice, fraction to decimal conversion list for memorization.
6th grade- Convert fractions to decimals, percents, mills, interest, principals, rates (of loans, rent and fares) , time, simple and compound interest, commission (retail & wholesale), net proceeds, special sales & discounts, taxes (city, state and federal and why we have them), ratio equivalents

I am so impressed with what Waldorf students must be doing in 6th grade math. I didn’t learn most of this stuff until much later and some of it like rates of payment, interest and loans I don’t remember ever being taught in school….though I do remember they were problems I couldn’t do on some of the tests I took. Although I don’t agree with all of Rudolph Steiner’s philosophies, it is apparent from this book that the teaching content and methods within this book are written to be developmentally appropriate. In constructivist teaching, a teacher is there to guide each student through their own process of learning. Put another way, the teacher helps students construct their own learning as opposed to telling them what to do and often how to do it. I may have to do a whole blog on constructivism given there is a lot of semantic disagreement among educators and critics.

I read once that mathematics is the true language that can explain our Universe. My first reaction was, “Cool, so how does it work?” Most of the people who surround me have incredible math anxiety so trying to get people to even enter into a creative and abstract conversation about mathematics proves to be extremely difficult. So, since my friends who are mathematicians are extremely busy teaching or running for public office, I decided to investigate this one on my own. (If any of my mathematician friends reads this and would like to chime in with your perspective, please do so!)

Normally, we describe the world around us by using our senses. They sky is grey and blue. The air smells of sod and rainwater. The sun is setting atop the mountain in the horizon. Well, that last one we know that the sun isn’t the sphere setting, it is our earthly sphere that spins. In addition to describing the world using our senses, we also describe it with reason, that is, what we know to be mathematically true. If you were to ask ten different people to describe the sunset, you would likely get ten different answers. That is because people have different perspectives, they notice different things and they disagree on many ideas and descriptions as a result. All of these ideas and descriptions are based on differently people’s perspectives and can therefore be called “variables,” or, things that change. In order to be sure we communicate exactly what we intend to and in order for everyone to describe something the same way over great expanses of space and time, we need to use “constants,” or things that don’t change. Almost everything in our world changes except mathematics. 7+4 has always been 11 and in 1,000 years it will still be 11. For a clearer understanding, here is a quote from a most intriguing and thought-provoking book I’m reading by Jostein Gaarder called Sophie’s World: A Novel About the History of Philosophy:

“Plato found mathematics very absorbing because mathematical states never change. They are therefore states we can have true knowledge of. But here we need an example.
Imagine you find a round pinecone out in the woods. Perhaps you say you “think” it looks completely round, whereas Joanna insists it is a bit flattened on one side. (Then you start arguing about it!) But you cannot have true knowledge of anything you can perceive with your eyes. On the other hand, you can say with absolute certainty that the sum of the angles in a circle is 360 degrees.” (pp 86-87).

Another enlightening book I found is a mystical, historical and scientific view of mathematics. It is a fascinating book authored by Michael S. Schneider called A Beginner’s Guide to Constructing the Universe: The mathematical archetypes of nature, art, and science- A Voyage from 1 to 10. Schneider takes the reader on a journey through each of the numbers 1-10. For example, chapter five is entitled “Pentad” the Greek philosophers term for the number five. The reader discovers connections from the number five to Fibonacci numbers, the golden mean, pentagonal symmetry in architecture, religion, ritual and more. Slice open an apple and you will see five seeds in the shape of a star. More living things from nature have pentagonal designs such as a sand dollar, starfish, sea cucumber, human body and a microscopic radiolarian skeleton. This book is stuffed to the brim with information that aids the reader in thinking about mathematics in a whole new light and understand in a deeper way, how mathematics describes the universe (and vice versa!).

One of the popular debates about mathematics is which came first, mathematics itself and then humans “discovered” it, or was it non-existent until a human thought it up and developed from that idea into what it is today?

What I Read:
http://www2.ed.gov/programs/racetothetop/index.html

On November 18, 2009, the U.S. Department of Education and President Obama invited state applicants (Governor’s only) to apply for part of a $4 billion grant, with the applications due on January 19, 2010. This news sent many on a mad scramble for their slice of the pie, including state governors, school districts & programs, the American Library Association and  the Bureau of Indian Education Schools (the latter two were not invited to submit grant applications).

This “Race to the Top” grant is a result of the American Recovery and Reinvestment Act of 2009 (ARRA) Sect. 14005-6, Title XIV (public law 111-5). There will be 2 rounds of funding. The first deadline has already passed (January 19, 2010). The grants will be awarded to states who advance education reform by:

1. Adopting career-ready standards (The Common Core State Standards Initiative is the main one)
2. Building data assessment systems and using them
3. “Recruiting, developing, rewarding and retaining effective teachers and principals.” (ed.gov)
4. Reversing trends in lowest-achieving schools

ED.gov states that the states who will win these competitive grants are those who have “ambitious yet achievable plans for implementing coherent, compelling, and comprehensive education reform.”

Two states, Texas and Alaska have declined to submit applications for any of the grant money. Texas Governor Rick Perry is quoted in a NY Times article:

“We would be foolish and irresponsible,” Mr. Perry said, “to place our children’s future in the hands of unelected bureaucrats and special-interest groups thousands of miles away in Washington.”

Texas State Education Commissioner Robert Scott says, “Even if we won the full amount, it would only run our schools for two days, so for that we weren’t going to cede control over our curriculum standards.”

Texas stands to gain up to $700 million. Alaska stands to gain up to $75 million (grant amounts are dependent on state populations). It is unclear to me why Alaska is declining this money as I was unable to find any press releases or news statements on the issue. I have emailed Governor Parnell with my questions.

However, it is not to late for any state to still apply in the phase 2 portion of grant dollar releases. If a state failed to meet the phase 1 deadline or if a state’s application is turned down, that state may re-apply (or apply for the first time) by a June 1, 2010 deadline with winners announced in September. Current applicant winners will be announced in April 2010.

Chinese Abacus

The Abacus is an ancient calculator and the world’s first computing system made simply of wooden beads in a rectangular frame. Back when the Babylonians, Egyptians and Romans were carving out numbers into stone tablets and using pebbles in the sand, somebody out there was inventing abaci, the plural of abacus. Most historians believe the abacus was invented in Central Asia and only later traveled to China (which embraced it and improved on it) and to Europe (which preferred pencil and paper and therefore ignored it).

While there is a Japanese version of the abacus, the soroban, the modern chinese abacus, the suan pan, is to me, more useful given a crossbar that runs horizontally across the abacus dividing the “one” beads or “earth” beads from the 5, 10, 50, etc. beads or the “heaven” beads. If you look carefully at the photograph at the beginning on this blog, you can read the number 628. In the far right (ones) column, one heaven bead and three earth beads are represented. In the column second from the right (tens) you can see that two earth beads are represented which means twenty. Finally, in the third to the right column (hundreds), one heaven and one earth bead are shown giving 500 + 100 or 600 altogether.

There are few books and resources available in the west on how to use an abacus, let alone how to teach mathematics with it. Sluggishly however, the abacus is cropping up in various schools and educational organizations. For example, in Beaverton, Oregon (outside Portland), the Japanese Abacus Math School (JAMS) opened its doors in 2001. JAMS teaches children abaci functions and mental math. Their web site, http://www.jamsportland.com/index.html, says of using the abacus in education:

“Learning the abacus provides all of these skills and abilities. Children who learn the abacus generally achieve higher academic performance in all subjects because of the concentration skills the Abacus teaches them. They are simply more capable of looking at a problem and working it out mentally, before diving in. When this happens they become more confident and successful in all areas.”

With the abacus you can count, add, subtract, multiply and divide. You can also work with square roots and decimals. Lastly, one of the amazing functions you can do with a Chinese abacus is to work with binary numbers since it is separated. For binary applications, only use the top two beads for the (the heaven beads) zero and the one. Using the Chinese abacus for binary functions was invented much later than abaci were, it is merely a delicious by-product. Children in Japan, China, Malaysia and other countries generally begin learning the abacus at age seven (second grade). The abacus is an extremely tactile instrument that can be used in a basic way for young children beginning with counting and in a more sophisticated way as a child grows in his/her understanding of the base ten system and improves upon her/his ability to construct and deconstruct number (i.e. use mental math).

“As in the case of the abacus, a fine grained analysis of the origin and development of instruments may give insight into the dialectic relationship between practice and theory in the construction of mathematical knowledge (Bartolini Bussi & Mariotti, 1999, 1999a), and provide interesting suggestion at the educational level.” (Authored by Maria Alessandra Mariotti in her article, Influence of technologies advances on students’ math learning.”

If you or someone you know currently uses an abacus in the classroom for teaching mathematics to children, please let me know about your experience. If you’d like to begin but don’t know where, check out the links I’ve posted below. There are books and online tutorials for learning how to use an abacus (then it takes consistent practice to be fluid), there are workbooks for children that give them structured practice and there is a link on where to buy a Chinese abacus.

What I read:
http://www.corestandards.org/
http://www.edutopia.org/poll-common-core-state-standards-initiative (comments section)

The Common Core State Standards Initiative (CCSSI) is a joint effort by the National Governor’s Association (NGA) and The Council of Chief State School Officers (CCSSO) to embed common standards of achievement in both mathematics and English language arts (i.e. primarily reading).  Its purpose is to prepare all K-12 students for college and career success. Success in this case seems to be defined as being competitive and making money. The CCSSI is being called the College and Career Readiness Standards.

At the website http://www.corestandards.org/, the authors in charge of explaining and validating this initiative seem to imply that the purpose of education is to mold young children into business men and women ready to compete in the global economy. I cringe at the use of such forceful, economy-centered language and maintain that the ultimate purpose of education is an ethical task that demands we teach the next generation to pursue knowledge and truth (not money and power).

The CCSSI is (an):
“opportunity for states to collectively accelerate and drive education reform toward the ultimate goal of all children graduating from high school ready for college work, and success in the global economy.”

“to maintain America’s competitive edge.”

“to compete with not only their American peers, but with students from around the world.”

Another sort of weird power thing coming out of the CCSSI is that there is a Validation Committee already chosen who will verify that states have “accurately adopted the Common Core State Standards.”

I do have to give credit where credit is due and I have to say I was very much impressed with the CCSSI’s assessment statement. Assessment “will include multiple forms of assessment so that what a student knows and can do, not the form of the assessment, determines performance.” This leads me to hope that, as a nation, we are at long last, steering away from assessing knowledge and skills based on a single, primarily multiple choice, test.

However, the CCSSI is not actually taking on the task of assessment. Instead, it leaves this task to States to implement on their own. It also does not show any clear view of what the common standards are at any given grade level. It claims that the standards are for K-12 and not including pre-K. However the initiative as written, seems to be written for the graduating high school senior. The CCSSI math standards draft includes the following content:

1. Math Practice
2. Numbers
3. Quantity
4. Expressions
5. Equations
6. Functions
7. Modeling
8. Shape
9. Coordinates
10. Probability
11. Statistics

Given that a graduating senior should know both basic and advanced content and skills in statistics, where does that leave a third grade teacher for example? Additionally, I have grave concerns over who is going to give the teachers professional development time and access to this information? Theory and Practice are such very different animals, one doesn’t necessarily follow the other.

Other information I think you ought to know: Participation by states is optional but participants are more likely to receive federal (Race to the Top) money. The CCSSI is flouted as a state initiative but truly the National Governor’s Association is a National Organization based in Washington D.C.. Those declining to participate in the initiative are the states of Alaska and Texas, the territories of Guam and American Samoa, and the Commonwealth of the Northern Mariana Islands. If you know why any of these groups are not participating, I would love to hear from you about what you know.
