Since modern math instruction consists of showing students how to operate a calculator, this really isn't a mystery.

So when will Christie and his big dumb failure Schundler be arrested for attempting to defraud the government?

This sounds like me and my friends in college, when we were still engineering majors, trying to settle a check after dinner. We pretty much forgot how to do math without letters in it.

I'm sorry, I don't buy the fact that they can pass Calculus and not do simpler math.

Upon review of the article, there is indeed bullshiat afoot.

UNLIKELY TAG EXPLODES


I also firmly believe that not every person can grasp Calculus when they're in high school. Parents are often to blame here, they think their snowflakes can do anything (and a lot of times, the kids aren't dumb, they just can't grasp high math at a young age) so they pressure the teacher, and the kid still gets a good grade and goes to college underprepared.

That said, most high school graduates are even dumber than they used to be ten years ago. There's hope though, some are even smarter than the smartest of ten years ago.

I was in high school from '93-'97. My freshman year Algebra class was unleveled, meaning that those of us who could understand the material after simple instruction had to wait on those who needed a week to figure out 5x + 10 = 200, what does X equal.

Test scores in that class counted for a whopping 20% of the grade, the same amount that having a neat notebook did. Homework counted as 40% of the grade, meaning that if you could do all your homework and have your notebook organized in the way the teacher wanted it, you had a D to start with.

Needless to say, I'm not suprised by anything in TFA.

# Require remedial services beginning in 9th grade for students not proficient in the 8th grade test. Currently, remedial classes are mandated starting in the junior year.

No. Fail them and make them retake the year. Refuse to issue driver licenses or occupational/business licenses to anyone not proficient in 8th grade math, for God's sake. Require parents of failing kids to come in before/after work WITH THEIR KIDS for math tutoring.

# Establish district-level portfolios for each student to record all information about that student, including results of diagnostic tests administered at the beginning of the school year.

Absolutely. And begin moving those at the very bottom off into vocational programs. This "everyone can go to college" crap is not only incorrect, it's incredibly wasteful of time and energy, and it ends up increasing human misery rather than decreasing it.

# Allow local districts to choose intervention programs, off of a list provided by the state.


No. Allow local districts to hold students back without ANY fear of litigation or negative consequences from the state.

# Continue reviewing whether to provide high school diplomas to students in the United States for less than three years who haven't mastered English but appear to be making rapid progress.

No. Nothing else. Just no. Here and want a diploma? Learn the language.

Oh, and also do the following:

Bring back public recognition of superior student performance. Too many schools have gotten rid of the dean's/principal's list because of the widdle snowflakes feelings that are hurt when they don't make it. Screw that. Provide privileges to all students who EXCEL at grade level or higher math (and science, and...hell, everything). Make the rewards not just long-term (scholarships, etc.), but short-term as well (parties, on-campus parking, tickets to concerts/games/etc). Base it on tests that are graded equally and fairly across all students.

Scale back privileges based on sub-par performance. If you can't pass your math/science/english/reading classes, you don't get electives, and can't play sports or participate in any other school programs. Stay on grade level, and you get the good stuff.

As noted above, absolutely zero driving privileges or work permits for students who are under 18 unless they are on grade level. If you're failing to meet minimal standards, you don't need to be working or driving around -- you need to be studying.

Allow students to drop out at 16 (but, of course, not drive or work until 18 -- laziness should hurt). MAKE students drop out who consistently present a threat to other students, or who are disruptive to the learning process. Provide a public-funded vocational track to any student who wishes to learn a trade AFTER they have demonstrated 8th grade ability in the basics.

Test and track. There is absolutely no reason that the top quintile of students needs to be taught at the speed of the middle or lower quintiles. As long as there is the ability for students to mobilize across the levels, teaching students in ability-level tracks allows teachers to maximize student learning without losing the slowest or boring the brightest. Again, maximizing effort and minimizing misery.

Teachers should be evaluated based on the difference between the student's skills on day 1 of class and on day 180. If your class of kids makes progress (regardless of where they started) then you're doing the job. NO progress, no job. Seriously.

Make student misbehavior painful to both child and parent. Have the kid and parent assigned to trash duty on the campus as punishment. Make it sometime really inconvenient for the parent, so that they "encourage" their child to make appropriate choices of behavior. If a child engages in seriously problematic behavior during school, require the parent to pick the child up within one hour or face a $1 per minute daycare fee. Suspensions? No in-school-suspension at all. You're either at school learning or out of school doing community service. With your parent.

Probably varies from school to school but I was in high school around that time (graduated in 98) and tests were basically everything. Mrs. Yancovich (no relation to Weird Al, who I believe does not use the h) that I know of), I hated you at the time but you did teach me math. If you're still alive that is... and reading Fark. neither are too likely.

Wow that is exactly like my freshman Algebra class, but I was in school from 88 - 92. Attendance and quizzes accounted for the other 20%. I never understood why so much emphasis was put on the notebook. I also spent half of the class daydreaming while the teacher explained the same thing for the fifth time to some people.

Swear to God, when I was at PC, the Calc 2 "professor" I had freshman year actually turned to us at one point while working on a problem on the board and told us she couldn't remember basic math sometimes.

The girl in front of me almost broke her neck trying to check with me to make sure she heard right.

Programmer Shuman bowed his head along with the rest of them but remained unmoved. The Technician had done his share and was no longer needed, after all. He might have started graphitics, but now that it had started, it would carry on by itself overwhelmingly, triumphantly, until manned missiles were possible with who knew what else.

Nine times seven, thought Shuman with deep satisfaction, is sixty-three, and I don't need a computer to tell me so. The computer is in my own head.

And it was amazing the feeling of power that gave him.

SpaceLord: Hey, this makes sense. Calculus is just adding, an infinite number of times.

Not adding an infinite number of times, just finding the limit of finite sums.

I think we really need to have our high school calculus classes hit harder on the fundamentals of calculus that I didn't see until my fourth year in college.

If you can find the limit of a sequence, then you can find the limit of a series. Ex: 1/2, 1/4, 1/8, 1/16, ... goes to 0 in the limit. You apply the exact same method to show that the sums 1/2, 1/2 + 1/4, 1/2 + 1/4 + 1/8, ... converges to 1.14 or something about there.

After you've got series you can do Riemann sums. Find the area under a curve using any estimation method you want. That's the first value of your series- find another, more precise estimate and you've got a second value in your series. Continue refining the estimates, find the limit as they go to infinity and BAM you've got integrals.

To me, integration was hand-waving until I really understood what was going on.

I wouldn't be surprised. Our pedagogy is so screwed up that you can get an A in a physics class without knowing a damn thing about physics. High school, and to some extent undergraduate college, just teaches you how to read a question and find the right formula.

If you can do that in physics, you can do it in calculus. I got straight A's in IB/AP high school calculus, but even at the time I couldn't tell you what a limit, a derivative, or an integral actually were, or how they worked. I sure knew how to memorize the formula for integration by parts, though, and I knew enough algebra to be able to look at an equation and figure out how to arrange it to fit one of my formulas. But as far as I was concerned, I was just playing Sudoku with different symbols.

After reading most of the "Deliberate Dumbing Down of America" and "The Underground History of American Education" (both available free online) this should get the "OBVIOUS" tag. Students that can't do basic math while faking the records is just what the system is designed for.

The education system devolved to the point to where people who are good at school can essentially get any degree they want. They don't need to have any understanding or knack for the subject to get very high grades and graduate. Doing what the educational institutions value is the skill now, not the subject at hand. Do the homework, pass the tests. Don't challenge the teachers. Don't make waves. Be like everyone else.

I have encountered these people who got the degree they got because they were good at taking tests and writing reports. They are horrible. I'd rather work with someone with no degree that learned his profession the hard way.

If it's leaning against the wall, isn't it already on the ground?

Go Fast Turn Left: Test scores in that class counted for a whopping 20% of the grade, the same amount that having a neat notebook did. Homework counted as 40% of the grade, meaning that if you could do all your homework and have your notebook organized in the way the teacher wanted it, you had a D to start with.

My algebra teacher had this rule.

It was pointless. A neat binder does not do anything to help a student learn algebra.

You either need to clarify what you mean by "a 6 foot ladder leaning against a 10 foot wall" or you need to specify the angle that the ladder makes with the wall/floor.


The static angle that the moving ladder is making? I'm thinking it starts out somewhere between 0 and π/2, and decreases to 0.

I think that what you really need to ask in order to make this a solvable problem is "which end of the ladder is moving at 6 in/sec?"
