Passing on an Oldie About NCLB...

Found this somewhere long ago and just found it again while looking for old info on NCLB. Cute.

Reacting to Federal Guidelines, the state of Connecticut, which has been highlighted as a role model for student testing by the two U.S. Senators from this State, released the following memo:

In response to the Federal No Child Left Behind Act, students will have to pass a new grade-level exam to be promoted to the next grade level. In the hopes that it will be uniformly adopted by all the states, thus illuminating Connecticut to a glorious front runner position in education, it will be called: the Federal Arithmetic and Reading Test (FART).

All students who cannot pass a FART in the second grade will be retested in each of the grades 3-5 until such a time as they are capable of achieving a FART score of 80% proficiency. If a student does not succesfully FART by grade 5, that student shall be placed in a separate mentor program, the Special Mentoring Elective for Learning Language (SMELL).

If, with this increased SMELL program, the student cannot pass the required FART, he or she can graduate to middle school only by taking a one-semester course in Comprehensive Reading and Arithmetic Preparation (CRAP).

If, by age fourteen, the student cannot FART, SMELL or CRAP, he or she will earn a placement to an intensive one-week seminar. This is the Preparatory Reading for Unprepared Nationally Exempted Students (PRUNES).

It is the opinion of the Connecticut Dept. of Education that an intensvie week of PRUNES will enable any student to FART, SMELL and CRAP.

Hallelujah! Kinda... NCLB Whittled Down Again.

Well, now. Good news for a change. The horribly structured and absolutely Draconian NCLB (No Child Left Behind, or as I like too call it, Never Create Legislation Backwards) Law, GW's educational legacy, has lost a few more teeth. According to New York Times today, two more states are receiving waivers exempting them from the guts of the Law. This brings the total number of states exempt from this fiasco too 26! Now, my math ain't that good, but isn't that more than half the country?

Quote from the article:

“The more waivers there are, the less there really is a law, right?” said Andy Porter, dean of the University of Pennsylvania’s Graduate School of Education.
While I applaud the waivers as a signal that the Administration is finally waking up to the Dr Seussian world depicted by NCLB, it is sort of looking at things like a band-aid is all you need after being trampled by a herd of rabid buffalo. Another quote:
“It is another example to me of how we’re not focused on the right things in the American education conversation today,” Mr. Starr [Joshua Starr, superintendent of the Montgomery County schools in Maryland] said. “I have a lot of respect for Arne Duncan,” he added, referring to the secretary of education, “but it’s just sort of moving around the chairs on the Titanic.”

HIGGS! FINALLY!

Well, it finally popped up; the elusive Higgs Boson. Just reported from CERN by two independent research teams comprised of a total of 3000 scientists and engineers! See: Science Daily and Science Magazine Online for details. The Official CERN Press Release is also cool reading.

For those of you not too terribly familiar with the importance of this find, or for my AP Kids who fell asleep in May, allow me some Fizzix Pontification. There is a model (sorta full set of theories and such that works) that explains the way matter is built, how it behaves, what it's made of, and all that particle physics stuff. It's called the Standard Model of Matter (or SM of Particle Physics if you want to sound more imposing at a party...). It's basically a large set of relationships between all those subatomic particles that make up everything we see, touch, feel, or otherwise can detect and we call matter. You can think of it as a recipe for matter and the Universe. A great place to start learning about this stuff is Berkeley Labs The Particle Adventure. A laymen's outline? Sure.

  • All regular matter is made of only 12 Fermions (6 quarks and 6 leptons) and 4 Bosons (Force carriers). The Fermions are 3 "pairs" of each quarks and leptons. You may have heard of the quark somewhere along the line if you were paying attention in class. They make up what used to be called the Protons and Neutrons and a "zoo" of other subatomic particle. A proton is simply an AREA of space where 3 quarks, 2 "ups" and one "down" exist. The neutron is made of 3 quarks also, but 2 "downs" and one "up". The quark "pairs" are whimsically called 'up & down', 'charm & strange', and 'top & bottom'. Leptons? Some of them are strange named things, but you have heard of the electron. It's one of the 6 leptons. Leptons are the electron, tau, and muon and their associated neutrinos (electron neutrino, tau neutrino, & the muon neutrino). [NOTE: This does not include Dark Matter! We have no frikkin' clue on what that stuff is yet...]

  • For all of the details included in the Standard Model to work, there HAD TO BE a reason for mass to exist. Believe it or not, even though we've known about all these particles and how they interact, we've never really had a good explanation of what actually caused a particle, and thereby a group of particles that make up an object, to have mass! Why do I have a mass of 110kg? Why is a quark more massive than an electron even though they are the same "size"? Well? WHY?

    Enter English physicist, Peter Higgs. In 1964, he, along with a few others, devised a strange sounding things called "broken symmetry of the electroweak theory". Yeah, just saying that hurts, don't it? In it, he proposed this thing, a field, an invisible force field type thing, that had to permate all of space in order for a particle to actually have mass; otherwise, there was no reason for a particle like an electron to even have mass. Without this Higgs Field, an electron could just fly around at the speed of light and have no mass and be weird like. The Standard Model (which didn't really exist like it does today...) at the time had no explanation of why mass was mass. He further proposed that the Standard Model would be fine if there were a particle that "exuded" this invisible field, called the Higgs Field", and this predicted particle was dubbed the "Higgs Particle".

    So, what does all this mean?

    By the 80's this Higgs Particle had been mathematically shown to be a boson. Boson, besides being what I've called some of my bosses in the past, is the name given to a group of particles called the "force-carrier" particles. They include photons (EM carrier like light), gluons (hold quarks, therefore nuclei, together), and the Z and W Bosons. "Boson" is named after the Indian mathematical physicist, Satyendra Nath Bose, a contemporary of Einstein. Put these two names together and you get the familiar, but very misunderstood, Bose-Einstein Condensate; a topic for a later and much longer post. Bosons obey Bose-Einstein Statistics; meaning they CAN violate the Pauli Explusion Principle and occupy the same place at the same time and even have the exact same properties as each other; the same quantum state. "Regular" particles like the leptons and the protons and neutrons made from quarks must obey Fermi–Dirac Statistics where the Pauli Exclusion Principle holds power; they cannot ever occupy the same quantum states at the same time.

    Here is a great simple physical analogy from Dr. Matthew Bobrowsky, Physics Professor at University of Maryland:

    In the 1960s, Peter Higgs and a few other scientists proposed that there’s an energy field throughout the universe. This energy field is now called the “Higgs field.” The reason Higgs proposed this field is that no one yet understood why some particles have more mass than others.

    The energy field that Peter Higgs proposed would interact with particles to give them their mass. The idea is that massive particles interact strongly with the field, low-mass particles interact with the field only weakly, and massless particles don’t interact with the field at all.

    A good analogy for this is to consider things moving through water. The water represents the Higgs field. Some things (like fish) move through water very easily. These would be like low-mass particles. Other things (like me) don’t move through the water easily; so these are like high-mass particles — high-mass because they interact a lot with the water (Higgs field).

    The lightest sub-atomic particle is the electron, and the most massive is the top quark. Its mass is about 350,000 times the mass of the electron — about the mass of a tungston atom. Interestingly, the top quark is not more massive because it’s bigger. It’s actually believed to be the same (infinitesimal) size as the electron. What makes the top quark more massive than the electron is simply that it interacts more strongly with the Higgs field. Now, what you’ve been hearing about is not the Higgs field, but the Higgs boson. What’s the connection? The Higgs boson is the tiniest piece of the Higgs field, just like a single H2O molecule is the tiniest piece of water. So in our previous water analogy, the Higgs boson is to the Higgs field as a single water molecule is to a large ocean of water. Just as water is made of countless individual molecules, the Higgs field is made of countless Higgs bosons.

    CONCLUSION? So, this Higgs Field is an "invisible" energy field that permeates all of space that is caused by the presence of Higgs Bosons (the force carrier) and causes particles in it to have "heft" or mass. With it, the Standard Model is all happy and fuzzy... Yea...
