Silly Charter School Debate

I am becoming more and more weary of silly education debates. A case in point is the ongoing criticism of most charter school studies.

First, jumping from a study confined to KIPP to charter schools in general is quite the over-generalization (sorry for the tautology).

Second, if the charter school outperforms their neighborhood traditional school, parents who can, will naturally choose the charter school. Silly to criticize parents for a perfectly rational decision.

Third, everyone agrees that parent involvement is key. To criticize a charter for requiring parental involvement is also silly. (My only beef is the over-rigidity of some charters. I once tried to enroll my children in a certain charter while I worked in a boarding school. The local traditional school did not want my high-achieving kids. Of course, I could have enrolled them anyway, but why would I want to force a school to take them. That sounds like a recipe for disaster. The charter required every parent to volunteer one day per week, which of course, I could not do. I offered a number of service alternatives, all of which were rejected. The school lost exactly the type of involved parent they hoped to attract).

Fourth, if charter schools use their freedom to act to pursue policies they hope will improve academic achievement, it is useless to criticize charter schools for their success in raising academic achievement.

Most criticism of charter schools boils down to, “if charter schools were just like traditional schools, they would be just like traditional schools.” Beyond silly. In the case of lottery-determined enrollment we should expect lottery winners to outperform lottery losers. After all, out-performance is precisely the hope that motivated parents to apply in the first place. To call the out-performance “contaminated,” a word with strong negative connotation, belies quite a negative bias. We should not put charters in a damned-if-you-do-and-damned-if-you-don't position. If a particular charter tries an experiment and fails, it is silly to criticize charters in general. If a particular charter succeeds, it is silly to dismiss their achievement as non-comparable.

We should applaud successful charters, especially those who operate in low SES areas. It is counterproductive to dismiss the strong performance of any particular charter school. It would be far better for traditional schools to make themselves worthy to be parents' school of choice as they were when I was a kid (gosh over half a century ago). Finally, if we teachers cannot conduct our public education discussions with more logic and less bias, how do we hope to be able to teach our students critical thinking? The problem is succinctly represented by a comment from a teacher in an EdWeek article about charter schools, "Obviously as a public school teacher, I do feel a bias against charter schools." Why should a public school obviously be biased against charter schools just because you are a public school teacher? If we are critical thinkers able to teach critical thinking to students, we should know how to evaluate a question on its merits, regardless of our own personal status. I challenge you to put aside everything the union is telling you, and do your own INDEPENDENT research, which is, of course, the hallmark of critical thinking.

Common Core—Cart Before Horse

“You know the Tasmanians, who never committed adultery are now extinct.” ----W. Somerset Maugham

Reading over most of the back and forth on common core feels like a massive waste of time. The subtext seems to be that we need common core to raise academic achievement. Those against common core point to poverty as the real issue, and lament handing out a lucrative opportunity to those poised to profit. Those for common core point out that high-achieving countries have common core. However, as we all know, correlation is not causation.

You might as well call for more chocolate in schools. After all, the higher a country's chocolate consumption, the more Nobel laureates it spawns per capita, according to a now famous study. I suggest that although it is true that high-performing countries have national standards, those standards are more a function of the political culture than a thoughtful education decision. The US education system was once upon a time world-class long before common core was a twinkle in someones' eye. I personally benefited from the education panic that ensued after Sputnik, when school districts all over the US implemented many wonderful curricular programs without bothering to worry about whether there were national standards.

The problem with common core is not the idea of a nationally agreed upon set of learning objectives. I have worked with so many predetermined sets of objectives, standards, curriculum, whatever, that long ago I learned quality teaching does not depend on them. So go ahead, approve and publish a common core. It will make no difference.

What irks me is that proponents seem to believe that teachers NEED a written set of standards in order to teach well. Or that administrators NEED a written set of standards to give orders to supposedly autonomous professional practitioners with professional judgment. The very push for common core is a national admission that either our teachers are not competent professionals (regardless of certification), or that we believe our teachers are not competent professionals.

Recent articles on Ed Week lend support to the notion that the real problem is not lack of standards, but teacher quality. One teacher writes that the standards improved her practice. Great, but she should not have needed the standards to chide her into implementing the improvements she writes about. She should have done it on her own long before.

And why do teachers “see interdisciplinary opportunities” in common core, as if they never saw them before? Good teachers make cross-curricular connections every day, like this teacher:

As an English teacher, I have taught units on Jacksonian Democracy, math vocabulary, map skills, Jane Goodall and her experience with apes, the Holocaust, the scientific revolution during the Victorian Era...I could go on and on. Each of these units tied to elements from my students' math, science, and social studies classes.
If common core will push mediocre teachers in the right direction, wonderful. Only let us not pretend that it is the common core that improved the teaching quality. The fact is common core is causing a number of teachers angst as they “grapple with” how to implement common core in an environment of little or no guidance. For example,
“In some states and districts, little or no guidance is being offered on the issue for teachers, leaving them to grapple with achieving the right balance of fiction and nonfiction on their own.

Are teachers really wringing their hands and waiting to be told how to put together a great program for their classroom? Apparently they are. They seem to need someone to rewrite the comprehension questions for their basal texts as if they cannot do it themselves.

Not long ago, we wrote about a project to revamp the teacher questions in the country's most popular basal readers. The idea, as you might recall, was to use the existing basal readers—since most districts and states can't cough up the cash for new ones just now—but rewrite the questions so they reflect the expectations of the Common Core State Standards. Many of the questions that the basals suggest for teachers, they noticed, don't actually require students to read the text passages. They solicit students' feelings, or their unsupported opinions. The aim of rewriting the questions was to make them "text dependent"—one of the biggest areas of emphasis in the English/language arts standards—so that students have to grapple with the text in order to supply a solid answer.
For heaven's sake, just simply be a great teacher, common core or no common core. If the questions in your basal text are poorly written, I hope you wrote your own questions long ago, common core or no common core. Good teachers already have. Personally, a road map for every year (we used to call it scope and sequence) is a good thing. I got so sick of my own children studying the Salem witch trials year in and year out. I make my own academic road map for every grade and every subject. I call it my year plan wherein I map the content I want to cover to a calendar. I may allot more time for one content area than another. I mean I do not mindlessly divide the number of book chapters by the number of school weeks. I actually think about content.

Sometimes I get tired of reinventing the wheel all the time. If the states adopt a multi-year plan (call it Common Core if you want), I would take it as my skeleton and modify it as I wish to provide my students with the best quality education I can provide. The US already has a sort of de facto common core. Just look at which textbooks have been widely adopted around the country. For many teachers, the curriculum IS the textbook the administration gives them. Standards generally beget curriculum, just as state standards have done. Depending on your viewpoint, this may or may not be a good thing. Curriculum begets textbook content. For many teachers, curriculum is nothing more than the table of contents in their textbook. Their curriculum was the table of contents before common core, and will be the table of contents after common core is adopted. I really do not expect there will be any changes in the classrooms. The table of contents have never had any power to encourage effective teaching.

Besides the prescriptive assumptions behind common core, a comment by one "MGN" succinctly stated the problem with standards

Standards, for the most part, are not the problem. The problems are a) confusing standards with curriculum; b) coercing states to adopt standards to get Federal funding; c) mandating high-stakes testing based on those standards; d) using test results to evaluate the effectiveness of teachers, principals, schools, or districts; and most especially e) awarding high-value contracts for testing, test grading, or textbooks to anyone who directly or indirectly helped to create those standards.

So, Fine, go ahead and publish a common core. Just do not expect it to make a difference in the absence of a cadre of highly qualified teachers.

College for All Destined to Disappoint

When comparing the education systems of different countries,simply comparing test scores such as PISA or NAEP (or whatever) gives insufficient information to draw conclusions or set policy, but not for the reasons commonly cited. It is not that Norway has a smaller population, or that Japan's system is centrally managed, or whether a society is “homogenous,” or the tested population is comprised of “the best students.” The first step to comparing and evaluating different education systems is to understand the goals of the system.

For example, the goals of the Japanese education system are crystal clear and common knowledge. The main goal is for students to pass the university entrance examination. Passing does not mean exceeding some predetermined cut-off score. It means avoiding elimination. If there are openings in a particular university for, say, 3000 freshman, and 3050 apply, the test eliminates the lowest 50 applicants. The test score of the 51st applicant may be abysmally low, but it will still be a “passing” score. More typically, there may be 3000 slots, but 30,000 applicants. Passing scores will need to be very high, often around 95% correct on a test much harder than any SAT.

In America, ask a hundred people what the goals of the education system are, and it is like playing Family Feud. There is no real consensus. Society cannot decide what outcomes education should produce. Looking to Japan (or Norway or anywhere) as a model is unhelpful in such an environment. Nevertheless, we should ask whether the system is meeting its own stated goals. In America, with such nebulous goals, the question is hard to answer.

With Japan, the question is easy to state. Do Japanese students in academic high schools pass university entrance exams? First, we must understand there are three mutually exclusive high school systems. The students of two of the systems, vocational, and commercial, have no intention of taking university entrance exams. The students of the third system, the academic high school, are in the academic high schools precisely because they want to go to college. The only measure of learning that counts in Japan is the national university entrance examination.

By this measure, the Japanese marvel that American think the Japanese system is so great. It is true that when certain non-randomizing conditions are controlled, the Japanese still excel Americans on international studies of student achievement. By their own intra-country standards, they worry that so few students succeed. In a typical case, one year 309 students graduated from the Japanese academic high school where I worked. Of these 309 students only 93 thought themselves ready for the entrance exams and applied. Of those 93 only five passed. 304 students chose to continue studying for the entrance exams, attend a less-selective private university, or go to work. Of those who continued to study, only seventeen eventually passed the entrance exam. Thus 287 (or 93%) had to settle for less ambitious life goals.

The results indicate that even though Japanese students are learning, the Japanese education system fails to meet its express goals. The conundrum is that success would actually be a societal disaster. If entrance exams were a matter of exceeding a cut-off score, the universities would be swamped. Secondly, if all these university students graduated, they would expect to attain jobs commensurate with their education. Society does not have enough such jobs. No society does. No matter what the ideals, no society can absorb the success such ideals desire. Not Japan and not America and not anywhere. America's ideal of college for all is destined to disappoint.

The Success of Substitutes...

...is the school administration's responsibility. Fact is, if first-year teachers have to sink or swim, the waters are even more dangerous for subs. However, administrators are not there with the life-saving buoy for their first years,and they are even less there for subs. So subs need to help themselves.

We Teach Our Students to Misbehave...

… and then complain when they do exactly as we expect. A certain student came home from school reporting on a substitute teacher the class did not like. She began her report by asking me, “Doesn't a teacher have to let a student go to the bathroom if it is an emergency?” I did not answer; I asked what happened. The class in question took place after just after lunch. A girl came in, saw there was a sub, and began “dancing” near the classroom door. The teacher asked her to sit down. She continued to loudly make a scene. The teacher continued to ask her to sit down. The girl never did sit down, and continued to interrupt as the teacher tried to finish taking role. Then the teacher let her go.

After she left, several members of the class began asking the teacher out loud, “Why didn't you let her go? You have to let people go to the bathroom. What if it's an emergency?” The teacher explained that he would have let her go a lot sooner if she had just sat done when she was asked and allowed him to finish taking attendance.

Typical of many classes with a sub, there was a video which the teacher showed using the TV monitor. The students demanded out loud that the teacher put the video on the powerpoint projector instead of the TV monitor. The teacher refused. The students insisted their regular teacher always puts videos on the powerpoint projector. The teacher still refused. (an aside: students are really spoiled by all the technology available in classrooms these days. When I started teaching, we handed out purple, smelly mimeographs and showed filmstrips on a reel-to-reel. Some people reading this post may not have any idea what I am talking about. LOL)

My little friend came home complaining about what a mean teacher the substitute was. I guess she expected me to commiserate, and she was thoroughly astonished that I had an entirely different take on the incident. I told her the fault was with the students, not the the sub. First, the girl created a public scene when she could have walked respectfully to the teacher and quietly made her request. But no. She engaged in melodramatic, loud theatrics and essentially set a trap for the sub. She probably did not have to go to the bathroom at all.

Second, the students thought it was okay to question the teacher's response out loud, but worse, the teacher thought he had to answer their objections. Third, the students whined about the powerpoint projector. I told my young friend that no sub with a speck of common sense will do anything just because the students say the teacher does it. That is exactly the way to guarantee a whole period of one piece of nonsense after another. My little friend thought that perhaps her teacher forgot to write the part about the powerpoint projector in the lesson plans she left. Maybe so, I said, but the class will just have to do without, and they should never have been disrespectful to the sub about it.

She countered, “If we like the sub, we behave.” Wrong answer. Students behave because they are expected to behave whether they like the sub or not. Students have not the power, responsibility or authority to decide that they will behave “if we like the sub.” Liking the sub is irrelevant. Shame on our society for even giving such a wrong-headed notion any positive attention.

Then my little friend asked, “But what if the sub doesn't like kids?” What was she really saying, that kids have the right to punish a sub they decide does not like them? Wrong again. It is irrelevant whether “the sub likes kids” or not. Students are expected to behave, period. The problem in our society is that students did not get these wrong-headed ideas from nowhere. They have been socialized to them their whole lives. As a society, we do not really expect students to behave, the obligatory first day “expectations” lectures notwithstanding. In fact, I would suggest if we are still giving these first-day lectures to students older than about ten, both students and teachers have already conceded that students are expected to misbehave, regardless of our actual words. Furthermore, maybe we need to think a lot more deeply about what we mean by “student-centered.” In addition, there is tremendous pressure on teachers to avoid sending unruly students to the office.

As a junior high and high school teacher, I also gave the first-day lecture. I told the students I was doing so because I knew they were expecting one. I told them they had heard all the same expectations every first day since kindergarten, and now that they are secondary students, they get to hear the same expectations multiple times in one day. I listed the expectations anyway “on the off-chance there is even one person here who has not heard them,” and I explained the consequences of misbehavior. Faddish and wrong implementation of “democratic discipline” models leads to specious student “empowerment.” (Oh, I do hate buzzwords).

Up until this point, the students have basically tuned out what they have already judged to be merely a stricter sounding version of the usual first-day yadayada. But then, they all perk up when I say, “Here's the catch. There are no warnings. You guys are way too old for childish warnings. And I don't do second chances, and I do not negotiate.” About the third day, a student (usually a boy) will test me. I apply the consequence immediately and shut down the inevitable attempt to negotiate. Normally, I have no more problems during the year, because the thing is, students actually know how to behave. They just need teachers who genuinely expect them to. It is the Pygmalion Effect. When I had laryngitis while teaching in a school for "troubled" (read: disruptive) students, I learned that the students really do know how to behave. I learned to raise my expectations instead of my voice.

Japanese and Chinese students have a reputation for being well-behaved. I directly observed that overall, the expectation that students will behave is a Japanese societal given that does not require an annual review. Interestingly, a study found that “Chinese teachers appear less punitive and aggressive than do those in Israel or Australia and more inclusive and supportive of students’ voices,” and this in a country stereotyped to be just the opposite.

If you doubt that we encourage the very misbehavior we decry, check out this actual example from curriculum purporting to teach “critical thinking.” Really gotta watch for that “invisible curriculum.”

Do Not Use Baby Talk to Teach Math

Number sense is like a mighty oak rooted in the subconscious. Beginning in infancy, it is little more than a humble acorn. Misconceptions are weeds that also root in the subconscious and stunt the acorn's growth. The language we use to express number sense can nurture the acorn or plant the seeds of misconceptions. The resulting weeds are pulled only with great difficulty.

The baby talk some teachers use to teach addition can plant misconceptions that prevent students from properly developing the concept of mixed numbers. We should never, ever say, “2 and 3 makes 5.” Even a good quality text like Singapore Math talks baby talk, but that is because something was lost in the translation to English. We should say properly, “2 plus 3 equals 5.” Children are perfectly capable of learning correct language, and it saves them the trouble of unlearning it later. After all, we do not expect them to say “2 and 3 makes 5” forever. We expect them to transition to adult math expressions sooner or later.

So what is wrong with “and” anyway?

AND means something mathematically, and it is not “plus.” For example, 2½ does not mean 2 + ½. You do not believe me? How about -2½? Does that mean -2 + ½? Of course not, but that is not obvious to kids. The mixed number -2½ means “minus 2 and ½,” not “minus 2 plus ½.” more technically, it means “minus 2 and minus 1/2” or -(2 + ½). Subtracting a mixed number is often the child's first exposure to the distributive property, however I have never seen a textbook make it clear. Instead, we routinely plant misconceptions and then wonder why kids sometimes have so much difficulty with math.

It is not all that hard to teach either, especially if using money to illustrate. “If I have three dollars, and I spend two and a half dollars, how much do I left left?” I spent 2 dollars AND I spent ½ dollar. A seventh grade teacher mentioned in this blog the difficulty his own students were having.
I saw this post about a week after it appeared, and so I was prepared to prove MY 7th grade pre-algebra students would not make such mistakes. Equation-solving did them in, with this as a solution: -5¼ + 2½ = -3¾. I had previously showed them how illogical such a thing was, and how it didn't make "number sense", yet the method error persisted.

Break it out the way students do, and the thinking error emerges: -5 + ¼ + 2 + ½ = -3 + ¾ = -3¾. Our long custom of misrepresenting “plus” as “and” has led them to the idea that all you have to do is take out the plus sign and shove the fraction up against the whole number. If it is already shoved together, pull it apart, put the plus sign back in, and voila! The problem is solvable.

Because the root of the misconception is in the subconscious, even if they get some number sense training and even understand the training, they will fail to see the error of their thinking, and so the error persists. The teacher will probably have to name this misconception directly and explain to students how they were mis-taught in the past. They may then be able to pull it into their conscious mind and deal with it.

Decimal numbers might help. 37.2 is not “thirty-seven point two.” It is “thirty-seven AND two- tenths.” The function of the decimal point and the meaning of “and” is to differentiate the wholes from the part, whether in decimal numbers or mixed numbers (which brings me to another pet peeve. It is not that we are “converting” from decimal numbers to mixed numbers. Both forms are essentially the same: a whole number with a fraction). The decimal point does NOT mean “perform the operation of addition.”

AND is a mathematical operation called “union.” The performance of AND yields a result similar to addition only when the sets contain entirely discreet members. Otherwise, the result of the AND operation is a smaller number than the result of ADD. It used to be that AND (and OR) could be tough to teach. Nowadays, with Internet searches, lots of kids readily understand that search terms with OR between them will get you a bazillion, mostly useless hits, while search terms with AND between them will get you a smaller number of hits than each search term alone. Set theory using sets of hits makes sense, and a great way to exploit technology such that technology actually increases learning, instead of being the usual monumental distraction.

True, Authentic, Real Life Math Problem of an Eighth Grader

A certain student had recently missed much of the first quarter, so her band teacher did not count those weeks when figuring the credit for the weekly practice logs. Therefore, the student had only five weeks worth of practice log grades for the quarter whereas her classmates had ten weeks worth. She got 100% for each of the first three weeks she was back. When her report card came, she was shocked that she had a C. She thought she had an A in the bag.

Looking back at her practice log grades, she saw 100, 100, 100, 70, 0. “I forgot to turn in last week's practice log,” she explained. BUT, she knew how to figure averages, and when she did, she got 74%. “Ah, so there's the C,” she said.

Then she asked me, “How many minutes will I have to practice to bring my grade back to an A by next week?” True to form, I irritated her by telling her to figure it out. A real life math problem was staring her in the face. She had been wondering if there was such a thing as a real life math problem. “How do I do that?” she wailed. I told her to think about what she already knows and what she needs to know.

Her train of reasoning: One more week means I will have six total weeks of practice log grades. To average 100%, I will need 600 total minutes. I have 370 minutes. So I need 230 more minutes. I will need to practice 230 minutes this week. (An aside: I wonder if my teacher will give credit for so many minutes in one week). My practice log is due on Friday, so I have six days to practice 230 minutes.

So far, so good, but then her reasoning began to go awry. She divided 230 by 60, and got 5.5 on a calculator. She did not question the result. We need to teach students to determine the neighborhood of the result before doing any actual computation. I do not like to call this process “estimation,” because almost all kids have reduced estimation to mere rounding, and nothing more. Most kids tolerate estimation lessons at school, but basically tune them out because they have been socialized to value answer-getting techniques. Estimation does not, in their minds, yield “answers.”

(Now I have to explain that during this whole process, I was busy with my own work, so I was only seeing pieces intermittently, as she showed them to me. She showed me the calculator with the 5.5 in the display, which at this point was all I knew. I reconstructed her train of reasoning later from her comments).

I asked, “What does 5.5 mean?” She said, “5 hours and 50 minutes.” Remember, this student has all As in math, but as I have explained before, much of math in schools is misnamed. It is really non-math, but since schools call it math, students believe it is math, and if they get good grades in non-math, they believe they are good at math.

I probed, “How did you get that?” She looked at me like, well duh, isn't it obvious and said a little too loudly, “5.5 is 5 hours and 50 minutes.” Then turning away, she poked something into her calculator.

“How do I round this?” she asked. The display showed 0.9166666.

“You have asked the question wrong. No one can answer your question the way you asked it. You need to specify what place you want to round it to.”

“The thousandth's place. So 0.917.”

“That's right. But what are you counting?”

She pondered a moment and wrote 0.92.

“And what is that?” “Minutes,” she said, and wrote 92.

“How did you get that?”

“I need minutes, so I moved the decimal point.”

“'I moved the decimal point' is never a mathematical explanation for anything. You need to give a mathematical reason for the math you do. What did you do to get 0.92 in the first place?”

“I divided 5.5 by 6 to get the number of minutes I need to practice everyday. 0.92 minutes doesn't make sense so I need to move the decimal to get a number that makes sense.” (With this kind of reasoning, is it any wonder our students are so poor at math? And if they use the same faulty reasoning for any of life's other problems, no wonder decision-making ability is also poor. When they become adults, they are easily scammed by poor reasoning that sounds good to them).

She has three main problems:

1. Using disembodied numbers

Teachers have allowed her and her classmates to disembody numbers since first grade. What I mean is students have been trained to compute with only the numbers and attach the units to the result later. When students do that, they attach the unit they want, not the unit their computation produces. What she should have done is written 5.5 hours = 0.92 hours/day. Her unit was “hours/day.” However, since she was looking for minutes, she did the math the way so many students (and adults) do: 5.5/6 = 0.92 minutes.

2. Mixing bases

She did not realize that decimals numbers are base 10, and clock numbers are NOT base 10. I set up some place value columns for decimal numbers, and another set of columns for clock numbers. Then we did some counting so that she could see how numbers end up in the columns they do. First, we counted decimally, that is, in base ten. Then we counted time. As our paper time clock ticked over 59 in the minutes column to 1 in the hour column and 0 in the minutes column, she exclaimed, “Oh, base 60, like the Incas.” She could tell me that 0.5 = 50/100 = 50%, but still insisted that 5.5 hours = 5 hours and 50 minutes. She realized that she was looking for 50% of 60 minutes, but insisted she should divide 50% by 60. Eventually, understanding dawned. She realized that since 50% means half, then half of an hour is 30 minutes, so 5.5 hours means 5 hours 30 minutes. (My own work had come to a complete standstill long before). “So 'of' means multiply, right?”

3. Misunderstanding “Decimal Number”

She thinks, like so many kids do, that a decimal number is a number with a decimal point. Just take out the decimal point and presto, changeo, it is not a decimal number anymore. What else do we expect when we teach kids tricks,shortcuts and blind procedures,and call this strange conglomerate "math?"

In quite East Asian style, we had spent over an hour on this one problem. Eventually, she determined that (leaving aside the original calculator error), she actually had gotten her answer way back at 0.92 hours/day. She realized that the math had “spoken” to her if she had only thought about it correctly. What the math said was that she would need to practice a little less than an hour a day. She never noticed the calculator error, and I did not point it out.

Epilogue:

She practiced 60 minutes (in 30 minute increments) three days in a row. Then it occurred to her that if she practiced 60 minutes per day for 6 days, her total would be 360 minutes, not the 240 minutes she was expecting. She has not practiced for two days, but plans to practice 60 minutes on the sixth day. She got a real-life lesson in checking the math by plugging the solution back into the original problem, a step her teacher requires, but she resents as a time waster. We talked about that maybe her teacher really does have some wisdom in her requirements. She also admitted that her goal is to do the minimum necessary to secure an A. Excellence and doing one's best is just adult yadayada. At least her bar is set at A.
