Asilomar #1: What Do We Do With Algebra II

Session Title

Thoughts On Rationalizing Algebra In Ways That Serve Kids, Not Universities

Presenter

Steven Leinwand, Principal Research Analyst, American Institutes for Research

Narrative

The day before CMC-North I was trading notes with our lead counselor, just swapping stories about kids, when she mentioned a student who was at the end of her turn at the local community college. She’d be transferring to a state college to complete a liberal arts degree if it weren’t for a failing grade in Algebra II. Because she can’t yet perform long division on polynomials, she’ll have to postpone her degree in (just guessing here) linguistics a full year.

Leinwand opened his talk: “The great divider of our time is the Algebra II final exam. Algebra II squeezes off options for so many kids. Algebra II is anathema to all but the top 20% of the population. My premise: as currently implemented, high school algebra I and II are not working and not meeting either societal or student needs.”

He described the courses as “focused on increasingly obsolete and useless symbol manipulation at the expense of functions, models, applications, big ideas and statistics.”

He works with schools across North America and when he’s trying to get a feel for the tenor and rigor of their math programs, he asks for:

  • the courses they teach,
  • their course descriptions,
  • the books they use,
  • the balance of course enrollment,
  • last year’s final exams for every class.

He said they give him unrestricted access to the first four but balk at the fifth. He said, “if you want to engage people in discussion, go and get those finals.”

Leinwand asked, why are most Algebra II final exams balanced towards the verbs:

  • Simplify,
  • Solve,
  • Factor,
  • Graph.

… when math is ever so much more about being able to:

  • Find,
  • Display,
  • Represent,
  • Predict,
  • Express,
  • Model,
  • Solve,
  • Demonstrate.

Lynn Steen: As mathematics colonizes diverse fields, it develops dialects that diverge from the “King’s English” of functions, equations, definitions and theorems. These newly important dialects employ the language of search strategies, data structures, confidence intervals and decision trees.

Leinwand: “No one is saying throw out the old dialect, but what about the new dialect.”

This all came across depressingly but he ended on a hopeful note, citing several promising projects. Among them, The Opportunity Equation, which aims to:

… explore the feasibility of offering a mathematics pathway to college for secondary students that is equally rigorous to the calculus pathway and that features deeper study of statistics, data analysis, and related discrete mathematics applications, beginning with a redesigned Algebra II course.

He called the forthcoming Common Core math standards “the last, best hope” for meaningful math reform. He ended with a proposal for Algebra I and Algebra II curricula, paced at one chapter per month.

Algebra I

  1. Patterns.
  2. Equations.
  3. Linear Functional Situations.
  4. Representing Functional Situations.
  5. Direct and Indirect Variation.
  6. Data.
  7. Systems of Equations.
  8. Exponential Functions.
  9. Linear Programming.

Algebra II

  1. Review and Reinforce Big Ideas and Key Skills of Algebra I.
  2. Quadratic Functions.
  3. Polynomials and Polynomial Functions.
  4. Patterns, Series, and Recursion.
  5. Exponential and Logarithmic Functions.
  6. Rational and Radical Functions.
  7. Probability and Statistics.
  8. Optimization, Graph Theory, and Topics in Discrete Mathematics.

Visuals

PowerPoint. Black text on a white field. He introduced his slides with this, “These are terrible slides coming up. You want to read PowerPoint slides that break every rule of PowerPoint these are them.”

I felt sick. Leinwand had attended my PowerPoint: Do No Harm talk last year and I could only hope he hadn’t added that disclaimer on my account. He was wrong anyway. He used his slides as conversation pieces. Doesn’t matter to me that they were monochrome.

Handouts

None.

Homeless

  • There is a gentleman at the table across from me murmuring and nodding agreement at Leinwand’s every line. It would not be inappropriate to describe the atmosphere in this session as something like religious conversion.
  • New rule: “Legislators can’t require a test that they themselves don’t take and publish the results of on their websites.”
  • If you’re looking for an example from Leinwand of the “old dialect,” here’s one: rationalizing roots in the denominator of fractions. Here’s another: the conjugate in the same context. Can anyone make a case for that?
  • One of “the most honest and important documents in our business in the last five years”: the $3.1 billion budget State Superintendent Jack O’Connell submitted in response to Governor Schwarzenegger’s pressure to make Algebra I an eighth-grade standard.

BTW: Fantastic follow-up from Josh G.

All of this just highlights the real problem: universities and colleges want a gatekeeper. They want that extra way to filter admissions, because they have to do it somehow. Worse, they don’t want to be seen as the “easy” school to get into, because this lowers their respectability. (This also drives me crazy.) So they demand gatekeepers, whether or not those gateways are actually a more useful math education for their students.

BTW: I have attached Leinwand’s slidedeck here.

Just a little love where it’s due.


Best Group Blog

Sup Teach?
http://supteach.blogspot.com/

I shared a bus ride with Ian Garrovillas at CMC-North and then a table at a conference session with him, Scott Farrar, their friend Joe, and some young genial guy named Dallas and, man – you just want to staff a school full of people your own age like that. And that’d be a terrible school and no good whatsoever for kids but you couldn’t mistake the loose-limbed, hyperkinetic vibe at that table, a vibe that I lack at a school where the next math teacher up the seniority ladder from me is in his 40s.

SupTeach? brings that vibe post after post.


Best New Blog

Sean Sweeney
http://sweeneymath.blogspot.com/

Sean opened huge with a month’s worth of killer multimedia resources but his blog’s been dark since early November. Consider this my encouragement to keep at it.


Best Teacher/Individual Blog

Kate Nowak
http://function-of-time.blogspot.com/

Kate’s second year blogging has been a blast to watch. I don’t know if I just imagined a surge in self-confidence, but her wit has never been sharper and she hasn’t hesitated to hip-check some of the biggest names in edublogging. Toss in a post count that belies how hard she works on a full-time teaching schedule and my nomination is locked.


Best Individual Tweeter

Elissa Miller
http://twitter.com/misscalcul8

If you missed it, Elissa became a teacher on Twitter. Starting last summer and continuing into her preservice year, she badgered her followers relentlessly for advice on classroom management and for help with lesson development. Incredibly, her persistence only scored her more followers, which has weird implications for teacher preparation in the 21st century.


Best Educational Use Of Video / Visual

Rhett Allain
http://scienceblogs.com/dotphysics/

Rhett pairs diagrams in Keynote with LaTeX equations to explain the physics behind the punkin chunkin and other frivolities. I’m not sure there’s anything in his life he wouldn’t film with a FlipCam and analyze with Tracker if it meant a better (or at least more amusing) understanding of physics for his readership. I’m particularly fond of the running, one-sided dialogue he has with various TV personalities who fudge their physics computation even a little. Mythbusters’ Adam Savage will rue the day.


Most Influential Blog Post

Weird Kipp Op-Ed, Tom Hoffman
http://www.tuttlesvc.org/2009/01/weird-kipp-op-ed.html

Tom’s recent coverage of the Common Core ELA Standards was exemplary and some of the best eduwonkery you’d find last year inside or outside of a funded think tank. But that was a Tom Hoffman pasteurized and bottled for transport as far outside his blog as he could get it. Tom’s best piece last year, for my money, was his withering takedown of an op-ed by KIPP’s Feinberg and Levin, the kind of excoriation that reminds me to pause that extra second before I hit “publish” just to ask myself: “Is Tom Hoffman gonna punch a hole in my chest for this or what?”

What’s Wrong With This Picture?

I’m still compiling my notes from a very strange and very cool CMC-North. Until then, consider this graphic, ripped from children’s television by Bill Farren as a visual assessment for engineering students:

I have underrated the assessment question, “what’s wrong here?” I need to do more of that. It isn’t that tricky, though it is tricky to deliver that assessment visually, as Bill has done here. It’s trickier still to rip that visual from a kid’s show, packaging the whole assessment in the sort of scientific put-down of children’s entertainment that appeals directly to the inner misanthrope I keep loosely tethered on a fraying leash.

Comments are closed here. Tell Bill what’s wrong over there.

CMC – North 2009: My Playlist

a/k/a Asilomar 2009

I’m at CMC – North this weekend. CMC has cut itself back quite a bit in light of these Tough Economic Times. Nevertheless, past experience has set my expectations pretty high for this conference. My slate is particularly strong this year, also, with two sessions from Steven Leinwand (engaging presenter with an interesting approach to problem-based learning), one from Michael Serra (author of the least helpful Geometry curriculum I have ever used), and one from Allan Bellman (my teaching mentor at UC Davis). In the middle of all that I’ll be presenting my own material.

If you’ll be there, tweet at me (#cmcn09), drop a comment here, say hi. I’ll be blogging most sessions and I’ll update this post with links later.

  1. Thoughts On Rationalizing Algebra In Ways That Serve Kids, Not Universities, Steven Leinwand.
  2. What Do We Do With The Seniors?, Robert Loew.
  3. Don’t Just Cover Geometry, Discover Geometry, Michael Serra.
  4. Be Less Helpful, Dan Meyer.
  5. Lights, Camera, Action! Fun And Success For All In Algebra, Allan Bellman.
  6. Intriguing Lessons About How Math Is Taught And Assessed In High Performing Asian Countries, Steven Leinwand. Sick. Left the conference early.

Score One For The Forces Of Innumeracy

In these exponential times, I admit that even I find it easy to nod my head credulously at a passage like this:

When it comes to [Facebook’s] online chat function, 1.6 billion messages are sent every single day and 1.4 million photos are uploaded a second.

Not so Nat Friedman who crunched some numbers in an utterly classroom-appropriate exercise in unit conversion and calculated that this means everyone on Earth is uploading approximately 20 photos per day.

Which means I had better hurry up and get a Facebook account.
