Ebonics
Note the subtle switch from "may" to "will be." Evidence? Dr. Texeira thinks so. A couple of her more liberal colleagues think so too.
Ebonics, a dialect of American English that is spoken by many blacks throughout the country, was recognized as a separate language in 1996 by the Oakland school board.
So a school board is qualified to decide what is or is not a separate language? Wow! Those guys are really good out there in Oakland. But maybe they should have deferred to the folks at the Linguistic Society of America, who disagree with them. An article which took a very balanced view of the Oakland decision can be found here. It (and other articles I have seen on this decision) ignore the question of whether Ebonics should be called or language or a dialect, since this is only a matter of semantics anyway. However, it disagrees with almost everything else in the 1996 resolution. Quite an interesting read.
Len Cooper, who is coordinating the pilot program at the two city schools, said San Bernardino district officials do not plan to incorporate Ebonics into the program. "Because Ebonics can have a negative stigma, we're not focusing on that,' Cooper said. "We are affirming and recognizing Ebonics through supplemental reading books (for students).'
Translation: Because Ebonics can have a negative stigma, district officials plan to incorporate Ebonics into the program WHILE CALLING IT SOMETHING ELSE.
"At every step we will see positive results,' [Board member Danny] Tillman said.
Only in education do we make such conclusions BEFORE the results are out. Hey, Danny, why don't we wait until the END of the year and then objectively analyze whether or not the results were positive?
[Texeira] said a child's self confidence is tied to his or her cultural identity.
Huh? It is? Why? Because she says so? What's the basis for such an absurd position?
She compared the low performance of black students to starvation. "How can you be angry when you feed a family of starving children?'
I disagreed with the previously quoted sentence, but I was at least able to discern some actual meaning in it. But here I am at a complete loss. What does this mean? Can anyone tell me what either the tortured metaphor or surreal question means? This is the kind of obtuse thinking that I've come to expect from the edu-left. Sentences like this do not betray an inability to communicate as is often suggested; they betray an inability to think.

Calculus I
Calculus II
Probability & Statistics
Each course awards 3 semester hours of graduate credit (500 level or higher) from the School of Graduate Studies.
Can someone explain to me why a course in high school algebra merits 3 graduate credits?

Computer Education Research
http://www.csmonitor.com/2004/1206/p11s01-legn.html
From a sample of 175,000 15-year-old students in 31 countries, researchers at the University of Munich announced that performance in math and reading had suffered significantly among students who have more than one computer at home. And while students seemed to benefit from limited use of computers at school, those who used them several times per week at school saw their academic performance decline significantly as well.
Computer technology "is used too much and very unwisely in the younger years, and not wisely enough in the older years," says Todd Oppenheimer.

Big Surprise!
Boosting people's sense of self-worth has become a national preoccupation. Yet surprisingly, research shows that such efforts are of little value in fostering academic progress.
"Surprisingly"? I don't see what's so surprising. I'm not surprised. Are you surprised? The entire article is worth a read and can be found here.

Teachers Who Fail
[Thanks to DVD for the link.]More than half a million Florida students sat in classrooms last year in front of teachers who failed the state's basic skills tests for teachers. Many of those students got teachers who struggled to solve high school math problems or whose English skills were so poor they flunked reading tests designed to measure the very same skills students must master before they can graduate.
A Herald-Tribune investigation has found that fully a third of teachers, teachers' aides and substitutes failed their certification tests at least once. The Herald-Tribune found teachers who had failed in nearly every school in each of the state's 67 counties.
Nine percent of teachers failed portions of the tests at least four times, according to the Herald-Tribune study.

National Test of Student Math Skills
http://www.cnn.com/2004/EDUCATION/11/18/math.test.ap/index.html
The national test of student math skills is filled with easy questions, raising doubts about recent gains in achievement tests, a study contends. On the eighth-grade version of the test, almost 40% of the questions address skills taught in first or second grade, according to the report by Tom Loveless, director of the Brown Center on Education Policy at The Brookings Institution.
So, is the test flawed? Maybe...
The study analyzed questions from the 2003 math tests, and then determined a grade level for those questions based on the Singapore math textbook program. Loveless said he chose that program because of its clarity and strong international reputation, and he said it compared well to the math-class sequences used in states such as California and North Carolina. But using Singapore as a model presents skewed results, said Sharif Shakrani, deputy executive director of the National Assessment Governing Board. Math is taught differently in that country, with heavy concentration on computation early before other topics are introduced. U.S. schools go for breadth, he said, with more math skills to cover each year. Overall, he said, the questions on the national in fourth grade and eighth grade are commensurate with what's being taught in those grades.
I think I understand. If Mr. Shakrani is to be believed, it's not the TEST that's flawed; it's the instruction. Math is taught "differently" (meaning "well") in Singapore...
"I contend that if we do what he suggests, moving to much more complex skills, it would be akin to giving a test in Russian," Shakrani said. "We already are not doing well. If you increase the cognitive function of the math concepts and the way you test them, you will end up with scores so low you will not be able to make sense of the results."
OK, I guess I don't understand after all. WTH does this mean? Don't test at the appropriate level because the scores would be "too" low?? Then what are the exams measuring . . . and what are they supposed to measure???

Number of foreign graduate students down
A new survey indicates the number of foreign graduate students enrolling for the first time at American universities is down 6 percent this year -- the third straight decline after a decade of growth. Educators worry the trend is eroding America's position as the world's leader in higher education.
But the results of the survey, of 122 member institutions by the Council of Graduate Schools, are still alarming to educators. American universities are highly dependent on foreign students for teaching and research help, particularly in the sciences and in engineering, a field in which foreigners comprise 50 percent of graduate enrollment.
How did we allow ourselves to get into a situation where if foreign students do not arrive at our graduate schools in sufficient numbers, these institutions can't function properly ("alarming" is the word used in the article)? Surely, policies should be enacted to ensure that we have sufficient home-grown talent to fill these slots?

California Mathematics Draft Framework
http://www.cde.ca.gov/ci/ma/cf/index.asp
I’ll go over all the standards in more detail later, but for now I’ll make a few quick observations on the chapter on geometry.
- Students demonstrate understanding by identifying and giving examples of undefined terms, axioms, theorems, and inductive and deductive reasoning
- Students construct, and judge the validity of, a logical argument and give counterexamples to disprove a statement.
- Students perform basic constructions with a straightedge and compass, such as angle bisectors, perpendicular bisectors, and the line parallel to a given line through a point off the line.
- Students write geometric proofs, including proofs by contradiction.
- Students prove basic theorems involving congruence and similarity.
- Students prove and use theorems involving the properties of parallel lines cut by a transversal, the properties of quadrilaterals, and the properties of circles.
- Students find and use measures of sides and of interior and exterior angles of triangles and polygons to classify figures and solve problems.
- Students prove theorems and solve problems regarding relationships among chords, secants, tangents, inscribed angles, and inscribed and circumscribed polygons of circles.
- Students prove the Pythagorean theorem.
- Students know the definitions of the basic trigonometric functions defined by the angles of a right triangle.
- Students prove theorems by using coordinate geometry, including the midpoint of a line segment, the distance formula, and various forms of equations of lines and circles.
- Students know the effect of rigid motions on figures in the coordinate plane and space, including rotations, translations, and reflections.

Review of "A Core Curriculum"
Page 1: "A need to enlarge the scope of this Newtonian mathematics curriculum began to emerge as mathematics increasingly became a tool in the social sciences."
What exactly do social scientists need from math that is not covered by the standard curriculum? A course in statistics in lieu of pre-calculus or calculus has always been available for students so inclined. Beyond that, the traditional curriculum provides the training to "think mathematically" of which NCTMers are so enamoured. Replacing the "Newtonian" mathematics curriculum with a bunch of vaguely connected statistical concepts dooms students to a lifetime of misunderstanding and misapplying statistics to their daily lives. The unassailable fact is that calculus is still the keystone to understanding all of this allegedly "new" math.
Page 8: Dart Throwing Exercise - "Measure a distance eight feet from the target and place a piece of tape on the floor. Standing behind the tape, the dart thrower throws some number of times at the target."
The purpose of this exercise is basically to do a simulation to discover the percentage of darts that fall within the white area on the target. The mathematical point to take away is that the white area is 78.54% of the square regardless of how many circles are circumscribed in the square. Of course, the number of darts that could reasonably be thrown by the students is not even remotely sufficient to get a reasonable accurate approximation. Even if sufficient accuracy were somehow obtained, statistical fluctuations will ensure that the percentages will never be the same for all the scenarios.
Page 34: "Assessment matters: One approach is to incorporate more student self-assessment. Ask students to write a brief self-assessment after they have completed a written assignment. Writing in a journal is also a good way to get students to reflect on their own performance."
Page 37: "When the instructional emphasis is on concept building through situations reflecting real-world questions and activities, the assessment should be of a similar nature. Open-ended holistically scored questions, interviews, observation of group work, testing with the use of physical models like those used in instruction, and student self-assessment are appropriate approaches."
I will let these monuments of edu-speak stand on their own.
Page 73: "Our axiom is that concepts are more powerful than procedures and more accessible to more students."
Brilliant. Evidence? Experiments? Research? Fuggedaboutit. Assume the very statement you're trying to prove. Then nobody can challenge you. You'd think mathematics educators would be familiar with the meaning of "axiom," but let's go through the motions. "A self-evident or universally recognized truth; A self-evident principle or one that is accepted as true without proof as the basis for argument." Should we really be accepting the statement above as an "axiom"? Come on now.
Page 113: "Old habits inconsistent with the new must be discarded."
Whether or not the old habits were effective and whether or not the new habits are effective.
Page 115: "The half-life of the education of an engineer has been estimated at ten years. In one decade, half of an engineer's training will become obsolete."
This statement is constantly used in support of the plan to replace "Newtonian" mathematics with a statistics-based curriculum. To me, this statement provides support for the diametrically opposite position. If engineers trained with "Newtonian" mathematics can survive the obsolescence of half their knowledge base and continue to function effectively, then this is precisely the training we should give everyone.
Page 117: "Use inductive reasoning to develop ideas where deduction requires too many underpinnings. Consider postulating important chunks of content, then use deductive reasoning from that base of understanding. Conclude coursework with modest deductive systems."
This would destroy the entire logical structure of the deductive system under investigation. As the NCTM should understand, the purpose of introducing deductive systems in high school is not so much to present the material itself but rather to present the concept of a deductive system. Presenting it in the way suggested above would destroy the rationale for doing this and eliminate any educational benefit in doing it at all.
Page 117: "Encourage students to investigate questions of interest to themselves."
Without the teacher controlling this process, most of the questions investigated will be of no value and irrelevant to the content. The uncomfortable (to the ed school powers-that-be) fact is that certain avenues of investigation are fruitful and most others are not; the teacher must provide this direction.
"Reshaping Assessment"
Let's analyze this innocuous looking statement from the preface of A Core Curriculum.Analysis of students' written work remains important. However, single-answer paper-and-pencil tests are often inadequate to assess the development of students' abilities to analyze and solve problems, make connections, reason mathematically, and communicate mathematically. Potentially richer sources of information include student-produced analyses of problem situations, solutions to problems, reports of investigations, and journal entries. Moreover, if calculator and computer technologies are now accepted as part of the environment in which students learn and do mathematics, these tools should also be available to students in most assessment situations.
"Single-answer paper-and-pencil tests are often inadequate." – Why? What's the evidence for this statement?
"Student-produced analyses of problem situations" – What does this mean?
"solutions to problems" – Exactly how is this different from a "single-answer paper-and-pencil test"?
"Reports of investigations" – What exactly is a high school student qualified to "investigate"? Certainly, the occasional research project may be helpful and even desireable, but for the most part traditional techniques are a much more efficient method for imparting mathematical knowledge than student investigations. Of course, the premise of NCTM math is that this statement is not true. Fine, what evidence supports the thesis that student investigations are more efficient? I've never seen any.
"journal entries" – too stupid for words.
Most interesting of all is the last sentence. "IF calculator and computer technologies are now accepted . . . these tools should be available." They are using the very statement for which they are attempting to provide justification as their hypothesis. Nice.
In summary, what evidence supports the counter-intuitive notions that (a) high school students can handle complex, multi-step, open-ended (often ill-posed) investigations and (b) this is the best way to teach basic mathematical concepts?

Scary
Dr. Martin Haberman, Distinguished Professor in the School of Education at the University of Wisconsin-Milwaukee, in a talk entitled Can Teacher Education Close the Achievement Gap? given to AERA on April 2, 2002, in New Orleans, said:
I urge you to read his entire speech!The most efficient ways of recruiting and selecting the wrong people at the initial teacher preparation level i.e. those who will never take positions teaching diverse children in poverty or who will quit or fail if they deign to try - are the criteria most commonly used: a composition on why I want to teach, G.P.A., letters of reference, a basic skills test, etc. These irrelevant criteria are frequently used in traditional and alternative certification programs. Actually, undergraduate GPA does predict. If it is extremely high in courses outside of education it predicts quitting and failure.
Response to Comment
You may want to check the real statistics on graduate students in engineering in the US. Graduate students in engineering are more white than anything else, more native [than] foreign and most of the foreign went undergraduate in the US. However, the number have gone down a little.Thanks for the link to this data. It was most enlightening. However, you seem to have completely missed the point of what this data is actually showing. I was talking about mathematics and physics, and you brought up engineering. If you look at the data you provided, you will see that engineering actually has a considerably LARGER percentage of temporary visa holders than either math or physics. In fact, among all the fields represented in your data, engineering is the one with the largest number as well as the largest increase in temporary visa holders, and the percentage in 2002 stood at an alarming 49%! This is exactly what I’m talking about. I’m not sure exactly what you’re debating, unless it's that 51% native - 49% foreign is not a problem.
Your claims that students are more "white than anything else" that "most of the foreign went undergraduate in the US" are absolutely NOT supported by this data.
Edit (9/16/2007): In attempting to create a new graph with more recent NSF data, I accidentally overwrote the graph that was part of this post. Note that on the new graph using data through 2005 the engineering foreign visa student percentage is above 50%. See my blog post dated 9/16/2007 for more details.
Also, probably the total number of high students taking calculus in the US is greater than it has ever been before. Why do you keep claiming that US schools are failing. How many US high students graduate in 1964 were taking calculus?I checked; this is actually correct. The number of students taking calculus has gone up consistently since 1955 (the first year the AP Calculus exam was offered). Even more encouraging, the percent of students taking AP Calculus has increased. But these are absolutely NOT the students about whom I’m concerned. Even now, only about 2% of high school students take calculus. Anybody in this elite group is already a gifted math student who is going to do well regardless of what the school system inflicts on him or her. The students about whom I actually am concerned – and the ones whom US schools are indeed failing – are the ones who could be successful in math, science or engineering, but who are not provided with the skills they need because of the NCTM math idiocy pervading our high school mathematics curriculum.

A Non-Math Example
The following are the requirements for a social studies education major at a well-known and well-respected private school (which falls into the Top National University category in the USN&WR rankings). By the way, if anyone recognizes the school, I am in no way trying to pick on this particular institution; the social studies education major is pretty much the same across the country.
Subject matter:What exactly is a graduate of this program qualified to teach? This "major" consists of courses in a bunch of different fields, many of them 101 survey-type courses with no more than 3 courses in any single field, with the exception of history which boasts 4. But of course, history is the field with the most appalling gap of all, since it doesn't even include introductions to both U.S. History and World History, subjects that all social studies teachers end up teaching at some point! So we are told that someone is qualified to teach a subject when they've never taken even a college survey course in it.
GEOG 101 – Global Environment: Understanding Physical Geography
ECON 101 – Economic Principles and Problems
PSYC 101 – General Psychology
SOC 101 – Introduction to Sociology OR ANTH 101 – Introduction to Anthropology
POL 101 – American Government and Politics
GEOG 130 – Introduction to Human Geography
POL 150 – Comparative Government and Politics
HIST 201, 202 – World Civilization OR HIST 211, 212 – United States History
HIST 364 – History of [State]
One sophomore-level geography course
One sophomore-level economics course
One junior-level psychology course
One junior-level history course
Education:
Educ 276 – Exploration of Teaching
Educ 286 - Instructional Technology in Teaching
Educ 350 - Adolescent Development in an Education Context
Educ 352 - Exceptional Education
Educ 353 - Multicultural Education
Educ 377 - Teaching Methods and Instruction
Educ 378 - Practicum in Secondary Education
Educ 379 - Classroom Management
Educ 476 - Internship
This major is clearly in need of toughening up. It matters not if this major is populated by or avoided by "upper middle class white kids" or "Asian kids." If this major is toughened up and students who would complete it in its current state are scared away after it becomes "too tough," then them's the breaks and that can't be helped. We can not allow candidate supply & demand considerations to affect curriculum decisions.
It has been my experience in discussing this with a wide range of people that this major's deficiencies are immediately obvious to most people. Unfortunately, the same thing can not be said about the deficiencies in college math education majors. Perhaps that is because most people are more comfortable with the subjects above than they are with mathematics. Over the course of the next couple of weeks, I will attempt to make a strong case that the mathematics education major (and by extension, the high school math curriculum) is as deficient as the major described above, even if this is less obvious at first glance.
Response to Comment
Your logic reminds me of the military logic of when they are short of good special ops troops, they always come up with the idea of making training harder. I do not see how making high school math harder is going to encourage more upper middle class white kids to go into it.Your lack of logic (or lack of reading comprehension or interest in arguing for argument's sake -- I'm not really sure what's going on here) boggles my mind. You are completely missing my point; I can not believe that my words are that unclear. I will attempt to elaborate one more time, but I grow seriously weary of this.
- I am NOT saying that we are short of native students who complete mathematics courses. I AM saying that students who complete the pre-calculus curriculum in US high schools are not able to compete in college math courses with students who complete the pre-calculus curriculum in foreign high schools. Further, students who complete an undergraduate math major in US colleges are not able to compete in graduate math courses with students who complete an undergraduate math major in foreign colleges. To extend your special ops analogy, if we had plenty of special ops troops but when we put them against the special ops troops of other countries, they got slaughtered, surely the proper response absolutely would be more training. Do you disagree?
- I DON'T have the slightest interest in encouraging more upper middle class white kids to go into mathematics. I DO have an interest in getting (a) more students who complete US high school mathematics to have the tools to compete in an undergraduate math major and (b) more students who complete an undergraduate math major to have the tools to compete in a graduate math program. How you continue to translate this into "upper middle class white" is something I can not even begin to comprehend. Why upper-middle class? Presumably, mathematical ability is distributed normally with respect to income? I would assume that lower-middle class, upper class and lower class students can be as successful as upper-middle class students in math, science and engineering, so I don't understand your focus on that single group.
- The addition of term "white" just confuses me. I have repeatedly attempted to make clear that my point is NOT a racial or ethnic or cultural one. My point IS about U.S. versus foreign training. U.S. doesn't mean "white"; it could just as well mean black, Asian, Native American, or Latino (not that this last one is actually a race, but I will bow to the common mis-use of the word). How anything that I've said can be construed as referring to "white" only is unclear to me. When I point to a list of names as an example, my point is NOT that the names are not "white", but rather that (based on my experience - more on this below) they are not U.S. citizens. Yes, I understand that the United States are very much a melting pot, but in my fairly extensive observation of this matter, a Lu or Kim or Nguyen or Yagamuchi in a graduate mathematics program is overwhelmingly more likely to be from a foreign academic background than a U.S. academic background.
It will just encourage more of them to go into law so that they can spend their time second guessing and nitpicking people who can do math.The difference between your special ops analogy and the mathematics situation is that there is not a well defined special ops curriculum. Regardless of how much training you've inflicted on special ops troops, you can always choose to train more. With mathematics, there is a well-defined standard to complete (geometry covers topics A, B, C and algebra covers topics X, Y, Z ) and you're done. The curriculum needs to be exactly this hard and no harder (and no easier either). If the curriculum is at this appropriate level and students are "encouraged" to bail and go into law instead, then so be it. Watering down the curriculum to keep them doesn't do anybody any good -- not the students themselves or society at large. If this is truly the situation we're in, then we can train the few who are willing and able to complete this curriculum and continue to fill in the gaps with those trained in foreign institutions. That's not ideal, but it's hardly the end of the world. And it would give those few who are interested the tools to compete against the best that other countries have to offer on an equal footing. Can you imagine if we adjusted the difficulty of the medical curriculum to adjust to the supply of medical candidates? I'd be afraid to go to the doctor! Same thing that's true in medicine is true in mathematics -- there's a specified body of knowledge that needs to be covered, and our schools aren't covering it properly. That's the only point I've ever been trying to make.
PS, in my experience at a large, state university, most of the kids with Asian names are from America. Just look at the enrollment of Thomas Jefferson High School in Fairfax County Virginia (one of the three best public high school in the US). The school is 40% Asian. Also, I doubt that all of the Asian at UCLA or Cal-Berkley are fresh off the boat.Well, that's not MY experience, or the experience of any number of fellow students who did graduate work in numerous types of programs (math, physics, astronomy, engineering) and types of institutions all across the country. Since you don't actually have any facts to contradict this fairly broad experience -- TJHSST may well be a counter-example but I couldn't actually find any numbers to confirm this (not that one example would constitute disproof of my general observation in any case) and your speculation regarding UCLA and Berkley isn't actually proof of anything -- I don't see how we can productively continue this particular line of discussion.

En Francais (In French)
Filosofia Barata (Cheap Philosophy)
The ability to learn is a skill;
The willingness to learn is a choice.
[original source unknown; I first saw this in Dune: House Harkonnen by Herbert & Anderson]
All of us have our God-given talents, so there's isn't anything I can do about the first sentence. As superdestroyer and allen have commented, there are strong cultural reasons why many students are unwilling to tackle math, science and engineering. While this is a serious problem, it is not one which I am particularly qualified to address. My interest lies mostly (and as far as this blog is concerned, entirely) in the second sentence: the ability to learn is a skill. Our high school (and increasingly, college) math programs need serious attention if they are provide those who are willing and able to tackle these fields the skills they need to be successful.
Response to Comment
How to you where the graduate students at the University of Chicago went to undergraduate let alone high school? Want to bet many of those Asian sounding names are Americans?This is certainly possible. But my experience in graduate school would argue strongly against this. The students in graduate school with me with Asian sounding names almost universally did have foreign undergraduate preparation. And this phenomenom only becomes more pronounced when you climb up the academic food chain from the state schools I attended to the University of Chicago and other top schools.
My guess is that most of them just happen to come from social settings that emphasize hard work and do not look down at being "nerdy" but instead look down at being an "air head."Well, then, that's an additional problem in our culture beyond what I've been discussing. But that is neither here nor there as to whether our high school and undergraduate math preparation is up to snuff. It's not. At the college level, our high school graduates can not compete with students trained in foreign high schools. To see evidence of this, all you have to do is look at the obscene number of remedial courses offered at even our "elite" colleges. And beyond that look at the courses offered which are not labelled remedial but which should be covered at the high school level.
- Introductory Algebra (wth is this anyway?)
- "College" Algebra (this is just a rehash of high school algebra)
- Trigonometry
- Pre-Calculus (I'm willing to cut a little bit of slack with this one, but really it belongs no later than the senior year of high school)
This then becomes a domino effect. At the graduate school level, our college graduates can no longer compete with students trained in foreign colleges.
My argument is that most of the upper middle class white kids who are capable of taking the math prep courses in undergraduate do not want to put in the hard work for majors in math or science because it would interfere with their social lives and their drinking.
I'm not disagreeing with you. I agree completely with this diagnosis. But I see this as a third problem (beyond my original point that U.S. math education is lacking and your earlier point that our culture looks down on "nerdy" behavior). I'm really most interested in the first problem. If as suggested by your comments (and I agree for the most part), cultural attitudes are such that math programs are not well populated by U.S. citizens, then so be it. But those programs at both the HS and undergrad levels need to have a higher level than they presently have!
As a final point, I will mention that you are very much mistaken if you think that if they wanted to, the upper middle class "white" kids (Latinos can be white too, you know) can still do well in a rigorous college math major after the sub-standard math curriculum they complete in high school. A few quick thoughts on this...
- If you're not ready to take at the very least Calculus I (without preparatory "pre-calculus" courses and other such nonsense) your first semester in college, you will most likely never do particularly well in a math or physics major.
- Without prior experience in difficult courses (in whatever field) requiring tons of homework, these students are often unable to handle the amount of work it takes to do even moderately well in college math courses. This is not generally a skill one develops on demand as soon as its need becomes suddenly apparent. Failure is the more common response to this situation.
- Without the sharpening of the intellect that comes from an intellectually stimulating curriculum WAY before these students are even thinking about going to college, most of these students lack the necessary logical thinking abilities to be successful in such programs.
In my opinion, a sub-standard HS preparation in mathematics pretty much dooms these students to failure in undergraduate math, physics and engineering programs. Yes, the super-geniuses can always overcome this handicap and succeed. But the more average (who could have been successful in these programs if equipped with the right tools) will fail miserably.
