Featured Speaker Presentation: 'Who Owns the Learning?'
Who should be working harder during class? The teacher or the students?  In the "Age of the Empowered Learner" we can equip our students to take responsibility to manage a large proportion of their learning.  We can also empower our students to create content that contributes to the learning of their peers.   Research indicates that one of the most powerful strategies to improve learning is to provide students with self assessment strategies.  This talk will provide step-by-step strategies that creates a culture of the empowered self directed and collaborative learner.

Am I a frequentist or a Bayesian or a likelihoodist? The big inference debate explained.
The last century has seen a lot of discussion about how statistical inference should be conducted. The three main contenders today are Frequentism (the prevailing champion), Bayesianism (the hot contender), and Likelihoodism (the longshot with a powerful one-two!). Some recent academic buzz suggests that the times may be ripe for an upset. In this session I will try not to play favorites, but only provide commentary: who are the players and what do they stand for? What are their chances?

Folded Quadratics
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 three 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. Part 3 (newly minted): We may finally have a proof of the Nirenberg Conjecture! You won't find this anywhere else!

Quadratic Models without Quad Reg
When we want to find quadratic or exponential models for data, we have the option of having our calculator perform QuadReg or ExpReg. Neither of these regression techniques helps students deepen their understanding of transformations or sheds light on the graphs of the resulting models. We will use linear regression to find both quadratic and exponential models; the process can help students see how parabolas or exponential curves have been transformed to fit a particular data set.

What lawyers, doctors, and the MLB don't know: digging deeper with probability
Conditional probability is the probability that some event A happens, given event B happens (conditional upon event B) fools the experts every day, and often with dire consequences. What are some examples where we have seen this go very wrong? What makes conditional probability so anti-intuitive? How can we teach students to think about it differently so that they don't make the same mistakes? These are the kind of questions that we will investigate using some interesting real world examples (assuming no prior knowledge of probability rules and topics).

Bring American History Into The Math Classroom: Teach Probability With Punchboards
Gambling takes on many forms. A fascinating part of American gambling history is the Punchboard. Though now illegal for gambling, punchboards can be brought into math class to enhance an introduction to probability. A typical punchboard is made of pressed cardboard, anywhere from 3 by 5 inches up to 11 by 17 inches and about an inch thick. It has lots of small holes drilled in it, perhaps as many as 2000. Each hole contains a tiny piece of folded paper with a number on it and each hole would be covered with paper or foil. The rules for each board would be printed on the board along with a colorful theme/story about something that was popular in America at the time. Between 1910 and 1960, in states where they were legal, punchboards were commonly found in stores and bars. A customer would pay money for the opportunity to punch out one of the papers hidden in the holes. If the number on the hidden paper matched a winning number as described on the board, the patron wins. Winnings often were money, candy, or cigarettes. Because the winning numbers and their payouts are stated on the board, probabilities and expected values are relatively easy to calculate. This makes punchboards an excellent way to introduce probability to our students. It's hard to get students excited when we use contrived data out of a textbook. But when I take my colorful punchboards out of the cupboard and let them punch out a few of the hidden papers, all my students are motivated, curious, and attentive.

Reading Ancient Mathematics
Does your school have a classics department? Have you ever considered collaborating? I will follow Sir Thomas Little Heath in arguing that reading Euclid in Greek (or pseudo-Archimedes in Latin) is not piling inutility upon inutility, but exposing the student (or yourself) to classically precise mathematical exposition which is surprisingly accessible in its original tongue. I will give you a flavor of the experience of reading the ancient mathematics in its original form and present (in English) the arguments from short snippets of Euclid and Archimedes. Like me, you may be surprised at how modern and elegant this ancient mathematics seems when read on its own terms.

Learning Styles in the Math Classroom
We know that everyone has a different learning style such as left brain, right brain, auditory, visual, and kinesthetic. To connect more effectively with all of our students we need to be able to teach in all of these modes. 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.

Students Teaching Parents
In my algebra and precalculus classes I help students learn to apply the mathematics they study and learn to use technology appropriately. Since parents often purchase calculators, or iPads, or laptops to help their students with schoolwork, I like to give the parents the opportunity to see one example of how the students use technology in math. To accomplish this, I assign a "parent project" in which the student teaches one of his or her parents (or another adult relative if that is more appropriate) one of the applied projects we have done during the course. In this session, I will describe the components of the parent project, suggest some problems that students have used with their parents in the past, and share student and parent reactions to the activity.

How to Find a Spouse
You are seeking a life-partner and, obviously, want to find the best match possible. As you meet and date "candidates", you have the opportunity to determine how well matched you are as a couple. There are several rules to this dating game: 1) It is generally considered bad form to date seriously two different people simultaneously, so you consider each person one at a time. 2) You can date someone for any length of time, but eventually, you must either "select" them or say "no", and move on to another candidate. 3) No is forever. Once someone has been passed over, you cannot go back. Given that one must make their selection before seeing all the "candidates", how can you maximize the probability that you select your best match? This problem combines ideas of probability, discrete optimization, and calculus.

Classical mathematics (calculus/differential equations/statistics) has been the cornerstone of our understanding of the physical world for the last 250 years.  But there are many areas of life in which our classical models have not been able to penetrate.  New models are needed to understand such phenomena as traffic flow, the spread of forest fires, the fragility of communications networks, the spread of infectious disease within a social network, the origin of cooperation in a society of insects or of people and many other problems in the biological and social sciences.  In this talk we will look at new mathematical models of the world that have emerged in the last 15 years and get a glimpse of the mathematical methods our students will use in their careers.

It's impossible to know exact values for both the circumference and diameter of a circle, but that hasn't stopped us from trying. From before the time Archimedes squeezed a circle between polygons, we've tried to find PI by cutting circles up to make them rectangles or triangles, dropping needles onto grids, and even legislating exact ratios. This CWIC will be a 45 minute historical tour that brings unusual applications of algebra, geometry, probability, and politics all together for a common goal.

Reading Ancient Mathematics
Does your school have a classics department? Have you ever considered collaborating? I will follow Sir Thomas Little Heath in arguing that reading Euclid in Greek (or pseudo-Archimedes in Latin) is not piling inutility upon inutility, but exposing the student (or yourself) to classically precise mathematical exposition which is surprisingly accessible in its original tongue. I will give you a flavor of the experience of reading the ancient mathematics in its original form and present (in English) the arguments from short snippets of Euclid and Archimedes. Like me, you may be surprised at how modern and elegant this ancient mathematics seems when read on its own terms.

The Gini Index for Income Inequity
The Gini Index, a commonly used index for income inequality, is a real-world application of the area of a region bounded by a curve. The index uses basic concepts from data analysis and integral calculus to arrive at a measure for the relative degree of inequity of income distribution in a society. The Gini Index also can be applied to measuring the inequity of the distribution of other resources as well.

Am I a frequentist or a Bayesian or a likelihoodist? The big inference debate explained.
The last century has seen a lot of discussion about how statistical inference should be conducted. The three main contenders today are Frequentism (the prevailing champion), Bayesianism (the hot contender), and Likelihoodism (the longshot with a powerful one-two!). Some recent academic buzz suggests that the times may be ripe for an upset. In this session I will try not to play favorites, but only provide commentary: who are the players and what do they stand for? What are their chances?

Vectors and Regression

Most of us know that the regression line minimizes the sum of squared residuals, but most of us don’t know how our calculators actually produce a slope and intercept for a regression line. This session will provide an answer to the question “How did my calculator do that?” It turns out that our calculators and other software use vectors to compute regression equations. We will look at the vector basis of regression; a certain level of comfort with vectors will be assumed.

What are some examples where we have seen this go very wrong? What makes conditional probability so anti-intuitive? How can we teach students to think about it differently so that they don't make the same mistakes?
