  1. Re:Stop passing on the hate on The Case Against Algebra · · Score: 1

    More specifically: U.S. elementary-school teachers are the weakest at math, and the most hateful about math, of our entire college-going population. This suggests that we really need math-specialist elementary teachers like every other modernized country.

    I agree with everything you wrote there, except for the claim "the problem is the focus on grades".

    Thought experiment: Let's remove grades and just replace it with an honest pass/fail system about whether you've mastered the skills or not. Now the education majors are all flat-out failing all their math courses. And now they're surely even more upset, right? The problem is not really the grades per se, it's that the math/science courses are where there's an unavoidable demonstration that U.S. education majors are perennially the dumbest people going to college. And those people are then the ones in charge of teaching broken math to our elementary-school students, in a repetitive cycle. If anything, the grades (polite C's and D's to the weak students) are serving to mask how completely broken at math the education majors are; the fact that those same students are so confused as to think it's a GPA-number issue is just a Dunning-Kruger type effect.

    No, CUNY administration right now actually wants to get rid of even the most basic elementary algebra -- and even arithmetic! Check out the bottom of this page here for CUNY's current "List of Learning Objectives" required for all students: exponents, radicals, scientific notation, variables.... This is what they want to get rid of. Because only about 50% of open-admissions graduates from NYC high schools can pass a test on those subjects. See the sample tests on that page for the specific questions currently tested.

  5. Put This in Context on The Case Against Algebra · · Score: 1

    Hacker is a professor emeritus from CUNY in Political Science. He has a new book coming out right now, his second on the subject. He personally gets a lot of publicity for the "Man Bites Dog" headlines that can be written about the professor-who's-against math. (Also, he's a regular book reviewer for the New York Times, who usually start off his PR tours by publishing an op-ed from him.) On the other hand, CUNY administrators have plans to get rid of even the most basic math requirements (7th-grade level) for any of their degrees, so as to boost retention/graduation rates in the face of a tidal wave of unqualified open-admissions students from NYC high schools. Hacker gives them political cover for that project by writing stuff like this. Journalists don't know any better... heck, the writer of the Slate article actually thinks that pi is 3.14!

  9. Figure Out What Happened on April 7th on The Sad Graph of Software Death (tinyletter.com) · · Score: 3, Insightful

    Looking at the graph in the article, there's on obvious inflection point that occurs on 7-Apr. Prior to that, the two lines (opened and closed items) are basically tracking each other. After that point, the opened items (red) retains the same slope; but the closed items (green) switches to a different, shallower (but thereafter basically constant) slope. And thus the two curves veer away from each other from that point.

    So: What happened on 7-Apr? Did one or more developers quit, burnout, take a long vacation? Maybe they haven't been replaced yet?

    After that I'd try real hard to stop new features from coming in, and start thumbing through a Brooks book to look for suggestions in an emergency like this.

    I always think the same at the college where I teach; the single biggest attack surface, and the easiest to reach, is the large packed line outside the school on days when they decide to do universal ID checks.

It seems much safer on the days where a security guard is just alert and actually watching the people walking in, instead of doing mindless heads-down busy work checking ID cards.

  20. Re:Somebody's on the Pearson payroll on University Reprimands Professor For Assigning Cheaper Textbook (slate.com) · · Score: 1

    I actually do this in my classes. My department has an in-house written College Algebra text, but I recommend to my students as an "alternative" that they get Sullivan College Algebra, 8th edition, for about $5 online.

    Two things with this: One is that potentially I could, like the professor in the story, get in trouble with my department for this arrangement (it's a bit of a gray zone). Second is that the college bookstore can't stock old editions from the publisher. So it's a one-by-one acquisition process. You can't depend that students have it on day one; therefore I have to provide handouts for the first few weeks before they get books. And if you did this across the institution, you would likely deplete available sources of the old editions (e.g., I allow one edition back of Weiss Introductory Statistics, and I'm pretty sure that I've single-handedly caused the depletion of it at Amazon -- I already need to keep exercise lists two editions back, which is a maintenance problem when I adjust my assignments, and further back than that and certain exercises have values changed or don't exist at all). Online homework is chimerical, IMO; college students students should have the maturity to do their own homework and then verify with odd-numbered answers at the back of the book; when I tried online homework in the past, it just threw up more technical barriers for students to say they couldn't do it.

    So I agree with the GP that open textbooks are the way to go. OpenStax at Rice University recently upped their offerings quite a bit; not perfect, but finally over the threshold where I could work with them. I'm currently trying to puzzle out how I could switch to using their College Algebra and Introductory Statistics books, in the face of officially required in-house texts from my department.

    For published research. I have multiple acquaintances who are new professors who don't even write their own lectures (they are given canned PowerPoint presentations and tests from the department), and this is considered roundly to be a good thing by all parties, because it frees up time for the research by which all promotions and advancements are judged. Professors' primary job is research; teaching is a secondary side-issue.

    But other than that I agree with your observation on textbooks; they should have more authority.

    "Also known as the fucking reason chairs and vice chairs exist."

    Common misconception.

    The primary goal of university faculty is published research. Faculty are promoted for that, and effectively nothing else.

    The side-goal of university faculty is teaching students. This generally does not effect promotions or salary. I had a dean at a prior school laugh in my face when I said I thought I was valuable because I was an excellent teacher. "We don't care about that...", he said, "We can get any body off the street in to teach a class."

    My current school is better, and I do now have a position which focuses on teaching, but it is by nature non-tenure-track, and for significantly lower salary. I wish this could be changed, but the corporatized environment is making it even less likely over time.

    The "point" of having separate states in the U.S. was not remotely to provide different choices for where people could live. The "point" was that the various state leaders were simply going to refuse to join any union that didn't mostly keep their existing little fiefdoms -- most notably in the case of the slave-owning states. For an excellent read on how the sausage was made, consider Robertson's "The Original Compromise: What the Constitution's Framers Were Really Thinking".
