They do what they do.
Thinking about schools and peers and parent-child attachments....I came across one of my favorite posts .
THE CLASSICAL LIBERAL ARTS included logic, grammar, rhetoric, and geometry. Just as today's liberal arts, they were not for the purpose of learning a trade. They served the purpose of education, which, as Albert Einstein once observed, "is not the learning of many facts but the training of the mind to think."
Geometry, moreover, embraced logic, grammar and rhetoric, because it was approached purely verbally. There was no algebra, no symbols for "angle" or "equals." What the student saw, he explained. For geometry is based on looking, and the sensitivity it develops is the essence of science.
In the 4th century B.C., Alexandria in Egypt was the center of culture and learning, and it was there that the Greek mathematician Euclid assembled the most remarkable textbook the world has ever seen: the Elements of geometry and arithmetic. Written in simple, straightforward language, the Elements has been translated the world over, and through the centuries it has been the model for clear and eloquent reasoning. It was the first written work to introduce what is called rigor into mathematics. That same rigor -- What gives us the right to say that we really know? -- is part of the culture of mathematics today, and it is the model followed in theoretical physics. Anyone truly interested in what mathematics is, can have no firmer foundation than Euclid.
Efforts have always been made to express the Elements in the language of each time and place. The pages that follow are adapted from the translation by Sir Thomas Heath (Dover) as well as the edition of Isaac Todhunter (Elibron Classics)...

Why is it hard to start and stick to a SAT self-preparation program?Simple answer! Because there is so much “stuff” to read, and most of it is boring and sounds silly. Most of us have been there … Mom and Dad announced that they had a surprise for us. After a successful trip to Barnes and Noble, they slowly unveil the goods: a collection of fat and colorful books printed on cheap paper. Faking some enthusiasm, we grab the books and retreat to our room, hoping to find some peace. However, it is usually short lived as Mom and Dad announce that they expect us to take test Numero Uno on Saturday at 8AM. But, why? Our strong objections are simply rebutted by a stern, “Because so and so told us at the bookstore that it was important to take the test just like they do at the center. Oh well, let’s see what the books contain. Very soon, we are reading about strategies and tricks that ALL sound so simple. After a few pages, battling the desire to fall asleep, we decide to just take one of those simple tests. After all, we are not like Joe Blogg, that bumbling fool who gets tripped so easily. We work our way through the test finding as sole motivation the promise of a great score. Yeah, I’ll show Mom and Dad that I know all this stuff.
A few hours later, despite having gone well over the time limits, we announce to our unsuspecting parents that we may very well be done with the SAT. We give them our test and tell them, “Yep, go ahead, score it”. Mom, knowing better, passes the fat book to dear hubby. To your great surprise, you witness the fatidic apparition of more crosses than check marks. No, no, that can’t be. I am not Joe Blogg. How could I miss the third question? A level 2 question! The verdict comes in at around 550 for the math and verbal sections. Smartly enough, you did skip that stupid writing component. Dad does not seem too surprised and simply whispers, “Better luck next time,” A short week later, after many unsuccessful attempts to read more than twenty pages, the second test yields a similar result. While you avoided the same mistakes, other problems surfaced. That silly Reading Comprehension section just killed you.
Dad, as usual, does not say much, but Mom has a great idea. “Tomorrow, I’ll call those nice people at Prince Something Review or Kal Plan.” You accept this outcome with a degree of relief and are now doomed to sit through thirty to forty hours of organized torture. At least, if you fail, you could blame Mom and Dad.

People don't usually analyze the reasons for success, but they do analyze the reasons for failure. The company I work for has a thing we do called "root cause analysis" and "the five whys" where we dig and dig and dig to try to find the real reason for failure. We don't usually do this for successes. Maybe we should.
- The customer reported a primary key violation on table FOO.
- Why is the customer getting a PK violation on FOO? Because the software is trying to insert two records for the same thing.
- Why is the software trying to insert duplicate records? Because two threads are trying to do the same work.
- Why are two threads trying to do the same work? Because there's a bug that wasn't caught.
- Why wasn't the bug caught before release? Because we didn't test the multi-thread scenario.
- Why didn't we test the multi-thread scenario? We were going to test it, but we ran out of time. (Or, you could branch off in a different direction here and go with "Because we didn't know the software needed to support multiple threads of execution.")
- Why did we run out of time? Because "just a small feature request" was added to the schedule after we did the planning and estimation.
- And so on...
A girl rides her bicycle to school at an average speed of 8 mph. She returns to her house using the same route at an average speed of 12 mph. If the round trip took 1 hour, how many miles is the round trip.
A. 8
B. 9 3/5
C. 10
D. 11 1/5
E. 12
Use a simple formula for average rates ....How did he derive this formula?
(2 x speed1 x speed2) ÷ (speed1 + speed2) or in this case: (2 x 8 x 12) ÷ (8 + 12).
Most everyone will notice that the answer is 2*96/20 or simply 96/10. This yields 9.6 or 9 3/5. The total time to do this, probably 20-45 seconds. Not a bad method to know!
Up in my area of NY, folks (mainy blue collar [people who] work in NYC gov't agencies and came here for the 'good schools') could care less about charters. They see that concept as a waste of resources that would be better devoted to fixing public school. Essentially, they want the district to be the charter by having the state stop forcing full inclusion and go back to grouping by academic instructional need. Allow test out, allow honors courses, allow slow learner courses, have alternative school, but do not allow the inclusion of violent children, druggies, gang members, emotionally disturbed, mentally ill and severe needs to be an excuse not to offer a year or more's worth of curriculum to each unclassified child each year. They propose that unclassified disruptors/nonparticipants pay the difference in cost between the alternative school and the regular setting.
Additionally, they'd like to fire the teachers who are presenting rather than teaching or are incompetent or abusive. It's been six years since the middle school failed AYP and the taxpayers stopped the 'blame the student' game and funded 'extra help' and rTi. They want to cut costs by having the unclassified students learn the material in the classroom, not from the extra help/resource teacher.
On the other hand, some parents view this proposal as racist or elitist. They work behind the scenes rather than engage in debate at board meetings for continuing full inclusion. Homeschool, homebound, alternative, and private school numbers continue to increase as does the number of hours of 1:1 aides for the emotionally disturbed and behaviorally challenged, and the security guards to remove the violent and disruptive.
Our school committee has come out publicly against allowing our kids to go to charter schools because our public (town) schools are rated so well on the state tests. They want it to be a state law. Of course, these tests only indicate the percentage of kids who get over a minimal proficiency cutoff point. They claim that this means they provide a quality education, so kids should not be allowed to go anywhere else.
They see it as their money that they are losing. It's not an argument of marginal costs. They have experience with laying off teachers. It may not be a continuous function, but their argument is more fundamental than that. It's about control. Charter schools challenge that control.
When our son was at a private school (grades 2-5), one parent seemed quite satisfied that it wasn't a charter school that siphoned money away from her daughter's school. However, charter school money is not part of our town's school budget calculations. It's a separate budget category. School funding is primarily driven by the number of kids per class.
We got a certain amount of negative (elitist) reaction when our son was in a private school in the early grades. Now that he is back in the public schools and is headed to high school next year, everybody asks where he is going (because he is a top student). Apparently, it's elitist in K-8, but quite understandable for high school. When we tell them that he is going to the public high school, we get a lot of happy reactions. Perhaps it's a vote of confidence for where they are sending their kids.
"College readiness" is not a binary but a continuous measure, as Pondiscio says. Why doesn't New York state have all high school students take the SAT I (reasoning) and three SAT II (subject) tests, report the results on transcripts (including percentile equivalents), and let students, parents, employers, and colleges use the results as they see fit?
State universities should create online calculators predicting a student's chance of graduating based on his SAT scores and high school grades, based on their experience with past students, so that potential students can make informed decisions before enrolling in college.
Disasters teach more than successes.
While that idea may sound paradoxical, it is widely accepted among engineers. They say grim lessons arise because the reasons for triumph in matters of technology are often arbitrary and invisible, whereas the cause of a particular failure can frequently be uncovered, documented and reworked to make improvements.
Disaster, in short, can become a spur to innovation.
There is no question that the trial-and-error process of building machines and industries has, over the centuries, resulted in the loss of much blood and many thousands of lives. It is not that failure is desirable, or that anyone hopes for or aims for a disaster. But failures, sometimes appalling, are inevitable, and given this fact, engineers say it pays to make good use of them to prevent future mistakes.
The result is that the technological feats that define the modern world are sometimes the result of events that some might wish to forget.
“It’s a great source of knowledge — and humbling, too — sometimes that’s necessary,” said Henry Petroski, a historian of engineering at Duke University and author of “Success Through Failure,” a 2006 book.
Taking Lessons From What Went Wrong
By WILLIAM J. BROAD
Published: July 19, 2010
It seems to me that there is an obvious and probably unresolvable tension at work here. Tie a high school diploma to a high and meaningful standard and you will have boxcar numbers of children who will not measure up now or in the foreseeable future. Keep it low and you're essentially misleading a similar number to believe they have achieved a level of preparedness they have not. Advocate for a two-tier system, and you risk (as others have noted) a return to the bad old days.
At present, "college ready" is little more than a bumper sticker. The fact that only one in four kids (as based on the most recent ACT results) are prepared to do c-level college work in all tested subjects is ample proof that it's not an operative goal for high schools anywhere. Given the range of colleges, it's a slippery concept. Harvard ready is not the same as Hostos ready. The only possible solution of which I can conceive is for state assessments to give families meaningful feedback not on the equally ephemeral concept of "on grade level" but whether or not a child is on track for acceptance within that state's university system--and guarantee a seat if so. New York can't say I'm Harvard material. But they certainly should be able to say if I'm SUNY material.
Regents Approve Scoring Changes to Grade 3-8 Math and English Tests
July 19, 2010
To help inform the Regents deliberations, the Department – together with testing experts Daniel Koretz and Howard Everson (both are members of the State’s Technical Advisory Group) and CTB/McGraw-Hill, the state’s assessment contractor – conducted a series of studies and surveys concerning student cut scores and student proficiency. Among their findings were the following:
- Nearly a quarter of students in all New York State two and four-year institutions of higher education take remedial coursework;
- Students taking more remedial courses in their first year of college are less likely to persist in higher education;
- Students who score below an 80 on their math Regents exam have a much greater likelihood of being placed in a remedial college course;
- Students who score above an 80 on their math Regents exam have a good chance of earning at least a C in college-level math;
- Students who score at least a 75 on their English Regents exam have a good chance of earning at least a C in Freshman Composition;
- Institutions of higher education around the state consider a score of 75-85 on Regents exams to be the bare minimum for college readiness;
- Students at the current Level 3 proficiency standard on their 8th grade math exam have less than a 1 in 3 chance of earning an 80 on their math Regents;
- Students in high need districts at the current Level 3 proficiency standard on their 8th grade ELA exam have about a 50-50 chance of earning a 75 on the English Regents;
- Students scoring below 80 on their math regents and below 75 on their English Regents exams have a high likelihood of scoring below 500 on the SAT.
The technique proposed by Malcom McCallum to encourage discussion of scientific papers is one of the many creative ideas that ecology teachers have developed to engage our students. While Malcom was able to use some creative assessments as well as his observations of students to support his conclusions, I would encourage everyone to consider how we could measure learning gains before we implement new or novel teaching techniques.
Dr. William Bromer
editor of Ecology 101
Dr McCallum describes a common classroom situation: trying to get the students to actually read a scientific paper. You'd be surprised to learn that this is not as easy as it sounds, because reading and understanding a scientific paper is difficult. In these classes, the professor would assign a paper or series of papers and one student would act as the presentor of the paper while the others were the student "presentees." To ensure that the "presentees" also read the paper instead of passively sitting in the classroom or texting their friends, the professor would either reward or force student questions and discussion. To do this, some faculty awarded points for each question asked. Others asked questions about the paper on exams. Frequently, "participation points" would be awarded to force individual participation.
"In fact, the many different angles used by professors in my many classes all ended the same way," writes Dr McCallum in his paper. "Inevitably, a growing number of students did not read the papers unless they were the presenter."
To engage all his students, Dr McCallum devised and tested an innovative method in the two-hour lab section for his senior-level environmental physiology class. The design worked like this: Dr McCallum brought two copies of 10 different manuscripts on critical thermal maxima. In this case, almost all of these manuscripts were by Victor Hutchison, and they were very similar except for the organism involved. Only one of the manuscripts was a review paper. In a classroom of 20 students or less, each student was given a different manuscript. Only a few students had a duplicate paper, so almost everyone was responsible for their own article. Then, the students were given roughly 15 minutes to read their paper in class. At the end of that time, Dr McCallum asked if everyone was done. If anyone was not done reading, they were given a little more time to finish.
After everyone had finished reading their paper, Dr McCallum randomly asked one student to briefly describe what their paper was about. After they had done this, Dr McCallum asked the other student who had that same paper if the first student's iteration followed their understanding. Invariably, the second student had things to add or ask. Then Dr McCallum randomly asked a student with a different paper to compare what they read in their manuscript to what the other two students presented. If a second student had read the same paper, Dr McCallum then asked that individual if s/he had anything to add. Then, Dr McCallum asked the presenters of the first paper if they felt that the comparison was accurate and to explain why (or why not). Dr McCallum found that continuing this scenario through approximately four papers led to a fluid discussion where only an occasional question from the professor was necessary to stimulate further participation Figure 1:
The result of this model was not only to circumvent many lazy student behaviors, but also to improve reading comprehension by familiarizing students with how to read, process, and evaluate complex scientific manuscripts in a short period of time. To test this hypothesis, Dr McCallum included a 10-point short-answer question on an exam that asked students to discuss the topic of the papers that were discussed in class. He found that almost all of his students had at least a working knowledge of the topic and 65% earned at least 7 points on this question. When compared to the more traditional "presenter-presentee" scenario used during the previous semester, only 33% of the students earned at least 7 points on a similar question.
But even more interesting was that Dr McCallum's students' GRE, MCAT, and ETS major field exam scores increased significantly. For example, the class averages for raw section scores in the ETS major field test in biology increased 12% from the previous year and 50% relative to students taking the same classes with other instructors within one year of introducing this technique. Additionally, the number of students entering graduate and medical school also rose.

Actually there is political opposition to charter schools from other than the public school officials. In my town, there is one of the best public charter high schools in the country (probably the best lottery-admission charter high school). The demand for the education it provides is high, with the chance of winning the lottery and getting it varying from 0 to 15%, depending on which grade you are trying to enter at.
It is continually being attacked as being "elitist" (despite the lottery admission).
I've seen political opposition to charter schools from parents who feel that any school choice (whether charter or magnet) diminishes the local neighborhood school. They want those families to stay and devote their time and energy to improving the neighborhood school. There are plenty of people who feel that any school other than the neighborhood school is inherently elitist.Glen:
Yes, it does: the teachers' unions, the politicians whose elections are paid for by the teachers' unions, and throngs of "progressives" who believe that progress means closing loopholes of liberty that threaten to grow and weaken state control over education.
Here in the San Francisco Bay Area, we have no shortage of "activists" who tell me that this "charter school business" is just the latest right-wing attempt to "destroy public education," "undo all the progress we've fought for for so long," "go backwards from a social justice curriculum to a right-wing traditional curriculum," and "maintain the status quo of oppression."
In an enlightened, progressive area like the Bay Area, a lot of people see any reversion of decision-making power from the state back to individuals, such as choice in any form in public schools, as the opposite of what they mean by progress.
