Featured Speaker Presentation: Heron, Newton, Euler and Barney

Heron's formula, giving the area of a triangle in terms of the lengths of its sides, is one of the great, peculiar results of plane geometry.  It is thus to be expected that, over the years, there have been multiple demonstrations of this remarkable formula.  Here, I consider four such proofs.  Heron's original was a clever if convoluted exercise in Euclidean geometry.  Centuries later, Isaac Newton gave a demonstration whose heavy lifting was done by algebra rather than geometry.  Leonhard Euler's proof was geometric and exhibited his characteristic flair.  Then in 1990 Barney Oliver, a former recipient of the National Medal of Science, shared with me an elegant trigonometric argument where the symmetry of the formula was mirrored by the symmetry of the proof itself.  The first two of these – Heron's and Newton's – I'll mention only briefly.  The second pair – Euler's and Barney's –  I'll prove in detail.  Taken together, these should remind us why the history of our discipline is such a fine source for wonderful mathematics.

Is f increasing at x=3?
Many folks assert that functions cannot increase "at a point". However, we calculus teachers continue to ask a variation of the question, "Is f increasing at 3?" without talking about what we mean. How can we assert that a function cannot increase at a point and then ask our students that very question. For some examples of calculus teachers asking such questions, see the 2013 Free Response questions which can be found at AP Central. This year questions AB/BC 12 and AB 2d asked if a function was increasing or decreasing at a point. I will posit a definition of "increasing at a point"and explore its ramifications.

Repeating decimals, magic squares and conic sections
We will begin by using technology to examine the period of the decimal expansion of fractions of the form 1/n, where n is a positive integer. We will establish some rules that can be used to predict the period without having to convert the fraction to decimal form. Our analysis will lead to a natural connection between certain fractions of the form 1/n and magic squares. We will end our exploration with a seemingly bizarre and stunning appearance of an ellipse and a hyperbola created from certain fractions.

Folded Quadratics: The Poor Person's Fermat's last Theorem?
First of all, you're folding the quadratic algebraically, not geometrically. If that's not enough to whet your appetite, then you are clearly not the kid who stood in a corner at a school dance. But come anyway, you could probably use the rest after all that dancing. The talk is divided into two parts: Part 1: A concrete, very specific example, of what we're doing and what will get (some) kids saying: NO WAY! Part 2: We generalize the concrete example in order to see why it works. To which everyone says: No way. You won't find this anywhere else!

Featured Speaker Presentation: Are we seeing the end of school, as we know it?

If ever there was a time to question the value of formal education, as we have traditionally called it, then surely that time has come. We are facing a critical time when we have to decide how much we want to hang onto the institution of school that we have traditionally known, and how much to let go of. Now is the time for us to determine what alternatives might not just be superficially appealing, but importantly they must be sustainable and impactful, and even more critically, to what extent any genuinely transformative shift might only be possible through disruption from external sources.

Many teachers teach in different modes, but presenting ideas to students becomes so much more powerful when the teacher choses the mode more deliberately based on the student's learning style. But... how do we recognize the learning style of an individual student? How can we present material more effectively by addressing each of these modalities? What is the result when a teacher is not aware of his/her own learning style? Drawing from his experience in the classroom, Nils will share his answers to these questions. He will also "teach"mini-lessons with the same content, addressing drastically different modalities of learning.

Scaffolding and PBL: Making the Most of Problems for Your Students
In what ways do students need support in a PBL curriculum? Whether project or problem-based, some students think they require the structure of direct instruction no matter what you say. Convince them otherwise by providing the right scaffolding "behind-the-scenes." Research shows that being exposed to problems that engage students at the right level allow them to advance in their knowledge securely. See examples of problems that allow for that advance and that don't and come hear of other ways in which you can provide for added structure that students can give for themselves.

Is f increasing at x=3?
Many folks assert that functions cannot increase "at a point". However, we calculus teachers continue to ask a variation of the question, "Is f increasing at 3?" without talking about what we mean. How can we assert that a function cannot increase at a point and then ask our students that very question. For some examples of calculus teachers asking such questions, see the 2013 Free Response questions which can be found at AP Central. This year questions AB/BC 12 and AB 2d asked if a function was increasing or decreasing at a point. I will posit a definition of "increasing at a point"and explore its ramifications.

With that in mind, the presenter will describe "perplexity," one of the scarcest resources in the classroom, and how to pick tools and technology to maximize it.

Visualizations, Animations, and Simulations
Helping students to experience mathematics through dynamic applications is a game changer for your classroom. Technology allows for powerful mathematical learning and connections to occur through statistical simulations, interesting animations, and helpful visualizations of abstract concepts. This session will show several examples of each from algebra, geometry, trigonometry, calculus, probability, and statistics. You will see a number of demos (using free software) that have really helped our students visualize why things work.

An Alternative to Precalculus
What to do with students who struggle in Algebra II? In this CwiC session Nils will share highlights of a year-long course he has written, designed specifically to meet the needs of these students. This course focuses on rich applications to explore the follow topics: transformations of functions, trigonometry, sequences, exponential and logarithmic functions, probability and simulation, and statistics. The course includes problem sets and solutions, PowerPoints and Excel files, data files in Fathom format, and instructional movies. The course is being used by a number of schools, is on-line, and free (http://www.ahbel.com/alternative-to-precalculus/).

Gerrymandering and Geometry
Every 10 years the US congress re-apportions the House of Representatives. Once the House is re-apportioned then state legislatures re-draw the districts. The shapes of these districts can be very controversial and sometimes law suits are filed arguing that there has been gerrymandering. In this session we will talk about some of the geometry of determining if a district has been gerrymandered. Typically students can develop some of the standard methods on their own. We will look at some ideas that my students have proposed and compare those with what have been used in the courts.

Repeating decimals, magic squares and conic sections
We will begin by using technology to examine the period of the decimal expansion of fractions of the form 1/n, where n is a positive integer. We will establish some rules that can be used to predict the period without having to convert the fraction to decimal form. Our analysis will lead to a natural connection between certain fractions of the form 1/n and magic squares. We will end our exploration with a seemingly bizarre and stunning appearance of an ellipse and a hyperbola created from certain fractions.
