Is college too much to ask?
In countering Murray, Anthony Carnevale (director of Georgetown's Center on Education and the Workforce) attacked his major premise, “that there is something in each of us that is innate and fixed, that doesn’t change over time. … It is true that cognitive ability affects people’s prospect in life, but it’s also true that people’s prospects affect cognitive ability.” In looking at high-scoring first-graders across incomes, Carnevale says 75% of the more affluent kids will still test high in fifth grade, compared to only 45% of the poorer students. That gap is not created by some inherent deficit in the children, he says, but to the quality of the educational opportunities afforded the two groups.

Carnevale (like most researchers looking at similar results) completely miss the point. They are confusing cause and effect. The largest factor influencing the facts that the affluent parents are affluent and the poor parents are poor is the cognitive ability of the parents, which IS hereditary. Therefore, the primary reason that financially disadvantaged students underperform is NOT financial; that is simply a side effect of the fact that they are below average on the cognitive ability scale.

Fake Diploma Mill Degrees
One fact from the article jumped out at me.
"The number of fake doctorates sold each year is in the range of 50,000 to 60,000," states John Bear, author of "Bear's Guide to Earning Degrees by Distance Learning." "The number of real Ph.D.s awarded is around 40,000."
Bear goes on to say "In America right now, more than half of all the Ph.D.s are fake." but that is not correct. I assume he meant more than half of all PhDs issued each year are fake.

Discussion of Physics Education Major
Requirement: A minimum of 25 hours, selected from the following list:
AST 3033 Recent Advances in Astronomy and Cosmology
ISC 3121 Science, Technology, and Society
PHY 2048C General Physics A
PHY 2049C General Physics B
PHY 3101 Intermediate Modern Physics
PHY 3221 Intermediate Mechanics
MAP 2302 Differential Equations or MAP 3305 Engineering Mathematics
PHY 3424 Optics
PHY 3802L Intermediate Laboratory
PHY 4040C Physics of the 20th Century
PHY 4323 Intermediate Electricity and Magnetism
PHZ 3113 Mathematical Physics
Of course, this looks quite reasonable on paper. The somewhat low 25 credit requirement is due to the fact that the major wants to accommodate introductory chemistry and biology sequences. But the first problem is that General Physics eats up 10 of the 25 credits. Then physics ed majors stay away from classes that physics majors take, so you end up with the following very unreasonable collection of courses:
PHY 2048C-2049C General Physics A&B (10)
PHY 3424 Optics (3)
AST 3033 Recent Advances in Astronomy and Cosmology (3)
ISC 3121 Science, Technology, and Society (3)
PHY 3101 Intermediate Modern Physics (3)
PHY 3802L Intermediate Laboratory (3)
Here's how I would toughen this up...
1) Given how often biology, chemistry and physics teachers end up teaching each others' classes, I agree that the 25 credit limit is appropriate and will work within its confines
However...
2) Physics majors have to take General Physics as a lower division prerequisite; I see no reason why physics ed majors could not do the same.
3) Drop the AST and ISC courses. No question. There's simply no room for this. Drop the Physics of the 20th Century course too; it doesn't count for physics majors - too fluffy.
4) This removes the elective nature of the existing list. Modern Physics, Intermediate Mechanics, Differential Equations / Engineering Mathematics, Intermediate Electricity & Magnetism, Mathematical Physics and Optics should all be required. But since this is just six courses, I have actually opened up space for two electives.
So we end up with the following eminently reasonable collection of courses:
PHY 2048C-2049C General Physics A&B (prerequisite)
PHY 3424 Optics (3)
PHY 3101 Intermediate Modern Physics (3)
PHY 3221 Intermediate Mechanics (3)
MAP 2302 Differential Equations or MAP 3305 Engineering Mathematics (3)
PHY 4323 Intermediate Electricity and Magnetism (3)
PHZ 3113 Mathematical Physics (3)
Two electives selected from courses that satisfy physics major requirements (6)
And I've even saved a credit. My proposed program requires 24 credits instead of 25.
Discussion of Math Education Major
When I argue that, at almost every college in the country, the math ed major is unnecessarily weak relative to the math major, the response I get is always that because of all the education courses required, there is not enough space left within the confines of a 120 credit degree to fit in all the courses that a math major usually takes. Fine, I will leave aside my opinion that the education courses are not anywhere near as valuable as the math courses they displace. I will work strictly within the confines of this restriction.
Let's look at one school's BS in math ed...
Subject Matter Specialization: Thirty semester hours of mathematics at the 3000 level or above including 3 semester hours in geometry, 6 semester hours in probability or statistics, and 3 semester hours in linear or abstract algebra.
This sounds rigorous, until you start dissecting it. First of all, the calculus sequence is somewhat oddly numbered 3000-level, so there's 12 credits right there. Then 6 credits of introductory statistics (also numbered 3000-level), 3 credits of linear algebra, 3 credits of geometry and 3 credits of history of mathematics, and you're at 27 credits without taking a single substantive upper-level college math class. One class (introduction to advanced mathematics is customary) and you're done.
Let's see if this can be improved...
1) First of all, math majors are expected to complete Calculus I-II-III and Linear Algebra as part of their lower division preparation. Since the math ed major does not require any lower division prerequisites, it should be possible for them to fit these courses into their first 60 credits the same as math majors. I've just freed up 15 credits.
2) Instead of the introductory statistics sequence designed for social science majors, I would require the Mathematical Statistics sequence that math majors are required to take. No change in the total number of credits, but I've just toughened up this requirement.
3) Geometry is fine as is. History of math is a little fluffy for my taste, but it is required by the state. No changes.
4) I would definitely add differential equations, which is a lower division prerequisite for the math major.
5) I would also require Advanced Calculus and Algebraic Structures. Together with introduction to advanced mathematics and mathematical statistics, this will give all math ed majors exposure to at least the common core required of all math majors.
To summarize, we started with the following course selection...
Calculus I-II-III (12)
Linear Algebra (3)
Introduction to advanced mathematics (3)
Geometry (3)
History of mathematics (3)
Introductory Statistical Methods (6)
And we've ended up with
Calculus I-II-III (prerequisite)
Linear Algebra (prerequisite)
Introduction to advanced mathematics (3)
Geometry (3)
History of mathematics (3)
Mathematical Statistics (6)
Differential Equations (3)
Advanced Calculus (3)
Algebraic Structures (3)
Two electives selected from courses that satisfy math major requirements (6)
Quite a difference, n'est pas? And all without removing a single education class.

Blog Post by Joanne Jacobs
Forty to sixty percent of students who start California schools as “English Learners” never reach full English proficiency; many won’t graduate from high school.
My article How Good is Good Enough? Moving California’s English Learners to English Proficiency is up on the Lexington Institute web site.
California schools lose funding when students are reclassified as “fluent English proficient,” an obviously perverse incentive. Many set high standards for reclassification: ELs have to do as well or better than the average native English speaker to qualify as proficient.
But the larger issue is that many ELs go to schools that don’t do a very good job teaching reading and writing to anyone. They’re not reclassified as proficient because they score below-average in English Language Arts on the state exam, even though they may speak “playground English” as their preferred language. ELs become proficient in English more quickly if they attend schools that focus on building the reading and writing skills of all students.
This isn’t really about teaching in English (more than 90% of ELs are in mainstream English classes) or teaching in Spanish. It’s about teaching well.

Dean at M.I.T. Resigns, Ending a 28-Year Lie
I continue to be amazed at the attitudes that come out when something like this happens.
"something she did long ago came back and trumped [the good she did]” said Leslie Perelman, director of the program in writing and humanistic studies
No, it's not someTHING she did "long ago." It's a pattern of lies stretching across 28 years. Every time she signed a letter with her "degrees" (which is quite common for directors of admissions) she was committing fraud. I am sure the back cover of the book she co-authored prominently features her "degrees."
I am not normally pro-litigation, but I hope every student who got turned down from MIT since she became dean in 1997 sues the school.

Software Has No Effect on K-12 Performance
Researchers looked at elementary and secondary classes in 132 schools. The teachers that participated used more than a dozen software products to help deliver their lessons. Nearly all the teachers received training on the products and believed they were well prepared to use the technology in their classrooms. When asked whether they would use the products again, nearly all teachers indicated that they would. The report was based on schools and teachers not using the products in the previous school year. Whether products are more effective when teachers have more experience using them is being examined in a follow-up study. The report detailed the effectiveness of the products as a group and did not review the performance of particular programs.

He has compiled a 2.9 grade-point average
He has 242 credits (that's 20/year - noticeably less than full-time)
He has accumulated $30,000 in student loans
He has majors in theater, communications, and liberal studies; his minors are in pre-school education, health education, and women's studies. (One could not get a more useless collection of majors by throwing darts randomly at a school catalog.)
UW-Whitewater is not even a national university; it's ranked as a master's university by USN&WR.

One comment stuck in my mind:
[...] Many teachers lack the skills to design homework assignments that help kids learn and don’t turn them off to learning. Today, schools of education provide varying levels of training in the art of designing homework assignments that are more than busywork, usually imbedded in courses about curriculum. Many, however, offer none [...]

Fox News Story on College
The most appalling error was a comparison of (a) lifetime earnings of college graduates minus tuition versus (b) lifetime earnings of high school graduates. So many errors permeated this story that it is impossible to explain them all, but here are the biggest (and keep in mind we're talking about a one minute clip here). Let's look at the smaller items before I point out the most egregious of the errors.
- The story used the earnings of an average college graduate, but tuition from an elite private institution (whose graduates will earn more than the average college graduate).
- The use of the average earnings of college graduates was incorrect, since the earnings of those who have MORE than a college education would have also needed to be taken into account.
- The calculation did not account for time value of money (interest, inflation).
Each of these errors changes the magnitude of the difference between the high-school number and the college number but does not have a huge impact. What most shocked me about this calculation was that it double-counted the effect of college tuition, and this DOES have a huge impact on the calculation - to the extent that it makes the decision come out the opposite of what they were saying in the story.
What they did was subtract tuition from the college graduates's earnings - fair enough. But then they also took the tuition money and projected it at (an unreasonably high) interest over the working lifetime of the high school graduate. You can't have it both ways! ARGH!

Interesting
It is dangerous show your students that you are wasting your precious time teaching these ignorant fools.
Note the choice of words. It doesn't say "have your students think that"; it says "show."
Repeat to your students, colleagues and to yourself that you like to teach.
And maybe you will even start to believe it.
No wonder the really high-end departments have such a reputation for bad teaching.
