June 22, 2015On behalf of the American Mathematical Association of Two-YearColleges (AMATYC), congratulations to the MathematicalAssociation of America on your Centennial! For 100 years, MAAhas been a leader in advancing the mathematical sciences. having ahuge impact on both teachers and students. The national meetingsthat are held and the publications that have been created by the MAAhave been key to keeping educators abreast with the latest research.The MAA’s Committee on the Undergraduate Program inMathematics (CUPM), has guided undergraduate curriculum inmathematics for many years. The association recognizes thatcurricular changes will occur and be impacted by the adoption of theCommon Core State Standards by many U.S. states. The commoncore will significantly change the preparation of incoming collegestudents and will necessitate changes in the preparation of preserviceteachers.AMATYC and the MAA have partnered on numerous occasions,through both MAA’s own Committee on Two-Year Colleges and itsCommittee on Curriculum Renewal Across the First Two Years(CRAFTY). These committees have provided guidance over theyears on the mathematics of the first two years as well as ondevelopmental courses in the mathematics.AMATYC is pleased to offer its congratulations to the MAA forsuccessfully reaching an important milestone.Nancy J. Sattler, PresidentAMATYC#MAAthFestWashington, DC | August 5–8, 2015 3

MAA MATHFEST 2015Invited AddressesEARLE RAYMOND HEDRICK LECTURE SERIESAlgebra Over Finite FieldsKaren Smith, University of MichiganHedrick Lecture 1Wednesday, August 5, 9:30 AM – 10:20 AMMarriott Wardman Park, Salon 2/3Starting with a little trick I learned inthird grade to check my multiplicationhomework, I’ll share my fascinationwith algebra as it grew through middle school, high school,college and eventually led to research in characteristic p rings.Along the way, I’ll point out the importance of many mentorsand teachers who led me to eventually pursue my career inmathematics.Hedrick Lecture 2Friday, August 7, 9:30 AM – 10:20 AMMarriott Wardman Park, Salon 2/3In the second talk, I will explain how doing algebra over finitefields can deepen our understanding of geometry. Specifically,I’ll discuss how understanding solutions to polynomialsover finite fields can help understand the geometry ofalgebraic varieties defined by real or complex polynomials.Miraculously, rings of characteristic p have some very specialproperties that can be powerful tools in analyzing them, oftenreplacing tools like integration for real manifolds.Hedrick Lecture 3Saturday, August 8, 9:30 AM – 10:20 AMMarriott Wardman Park, Salon 2/3In the third talk, I will explain some of these recent tools in“characteristic p” algebra–specifically Frobenius splitting andrelated tools–which have made an impact on different areasof math, including the minimal model program for complexalgebraic varieties and cluster algebras in combinatorics/representation theory. Some of this work is joint work with myPhD students and post-docs.MAA100 CENTENNIAL LECTURE 1Replicators, Transformers, and Robot Swarms:Science Fiction through Geometric AlgorithmsWednesday, August 5, 8:20 AM – 9:20 AMMarriott Wardman Park, Salon 2/3Erik Demaine, MassachusettsInstitute of TechnologyScience fiction is a great inspiration forscience. How can we build reconfigurablerobots like Transformers or Terminator2? How can we build Star Trek-stylereplicators that duplicate or massproducea given shape at the nano scale?How can we orchestrate the motion ofa large swarm of robots? Recently we’ve been exploring possibleanswers to these questions through computational geometry, in thesettings of reconfigurable robots (both modular and folding robotsthat can become any possible shape), robot swarms (which may beso small and simple that they have no identity), and self-assembly(building computers and replicators out of DNA tiles).MAA100 CENTENNIAL LECTURE 2Network Science: From the Online World toCancer GenomicsWednesday, August 5, 10:30 AM – 11:20 AMMarriott Wardman Park, Salon 2/3Jennifer Chayes, Microsoft ResearchEverywhere we turn these days, we findthat networks can be used to describerelevant interactions. In the high techworld, we see the Internet, the WorldWide Web, mobile phone networks,and a variety of online social networks.In economics, we are increasinglyexperiencing both the positive andnegative effects of a global networkedeconomy. In epidemiology, we find disease spreading over our evergrowingsocial networks, complicated by mutation of the diseaseagents. In biomedical research, we are beginning to understandthe structure of gene regulatory networks, with the prospect ofusing this understanding to manage many human diseases. In thistalk, I look quite generally at some of the models we are usingto describe these networks, processes we are studying on thenetworks, algorithms we have devised for the networks, andfinally, methods we are developing to indirectly infer networkstructure from measured data. I’ll discuss in some detail particularapplications to cancer genomics, applying network algorithmsto suggest possible drug targets for certain kinds of cancer.#MAAthFestWashington, DC | August 5–8, 2015 11

MAA MATHFEST 2015Invited Addresses (continued)MAA100 CENTENNIAL LECTURE 3Mathematics for Art InvestigationThursday, August 6, 8:30 AM – 9:20 AMMarriott Wardman Park, Salon 2/3Ingrid Daubechies, Duke UniversityMAA100 CENTENNIAL LECTURE 4Mathematical tools for image analysisincreasingly play a role in helping arthistorians and art conservators assessthe state of conservation of paintings,and probe into the secrets of theirhistory. The talk will review severalcase studies, Van Gogh, Gauguin, VanEyck among others.The Role and Function of Mathematical Models inInterdisciplinary Mentorship through Research:Lessons from the World of EpidemicsThursday, August 6, 10:30 AM – 11:20 AMMarriott Wardman Park, Salon 2/3Carlos Castillo-Chavez, ArizonaState UniversityWe live in an interconnected world inwhich seeking solutions to societalproblems no longer makes sensewithin the confines of single-disciplineorganized institutions. The nation’sability to train 21st century scientistsdepends on systems of learning andthinking that are naturally embedded within interdisciplinaryeducational research/mentorship models. The use of multiplemodes of doing science including the systematic use ofcomputer experiments and data science (Big Data) must be atthe heart of a modern 21st Century STEM education.As Steve Strogatz observes “… cancer will not be cured bybiologists working alone. Its solution will require a meldingof both great discoveries of 1953 [Fermi-Pasta-Ulamintroduction of the computer experiment and Watson & Creekdiscovery of the chemical structure of DNA]. Many cancers,perhaps most of them, involve the derangement of biochemicalnetworks that choreograph the activity of thousands of genesand proteins. As Fermi and his colleagues taught us, a complexsystem like this can’t be understood merely by catalogingits parts and the rules governing their interactions. Thenonlinear logic of cancer will be fathomed only through thecollaborative efforts of molecular biologists — the heirs to Dr.Watson and Dr. Crick —and mathematicians who specialize incomplex systems — the heirs to Fermi, Pasta and Ulam.”In this lecture, I will highlight (1) the role that interdisciplinaryresearch challenges has played in shaping the training andmentorship of students from high school to the postdoctorallevel and (2) the impact that has had on my own researchprogram. The discussion will be centered on questions that arisein the study of disease dynamics (Ebola and Influenza) acrosslevels of organization and over multiple spatiotemporal scales.The examples used are the result of the research carried outwith a myriad of collaborators (undergraduate, graduate,postdoctoral students and colleagues) over the past threedecades.MAA100 CENTENNIAL LECTURE 5CSHPM KENNETH O. MAY LECTURE“We Are Evidently on the Verge of ImportantSteps Forward”: The American MathematicalCommunity, 1915-1950Friday, August 7, 10:30 AM – 11:20 AMMarriott Wardman Park, Salon 2/3Karen Parshall, University of VirginiaThe American mathematicalcommunity experienced remarkablechanges over the course of the thirtyfiveyears from the founding of theMathematical Association of America(MAA) in 1915 to the establishmentof the National Science Foundation in1950. The first fifteen years witnessednot only the evolution of the MAAwith its emphasis on the promotion of mathematics teachingbut also the “corporatization” and “capitalization” of theAmerican Mathematical Society as mathematicians workedto raise money in support of research-level mathematics. Thenext decade, one characterized by the stock market crashand Depression, almost paradoxically saw the building ofmathematics departments nationwide and the absorptioninto those departments of European mathematical refugees.Finally, the 1940s witnessed the mobilization of America’smathematicians in the war effort and their subsequent effortsto insure that mathematics was supported as the Federalgovernment began to open its coffers in the war’s immediateaftermath. This talk will explore this period of optimism inwhich the American mathematical community sensed, asRoland Richardson put it, “we are evidently on the verge ofimportant steps forward.”12 Washington, DC | August 5–8, 2015 #MAAthFest

MAA MATHFEST 2015Invited AddressesMAA100 CENTENNIAL LECTURE 6Recent Results Toward the Birch and Swinnerton-Dyer ConjectureSaturday, August 8, 10:30 AM – 11:20 AMMarriott Wardman Park, Salon 2/3Manjul Bhargava, PrincetonUniversityOver the past half-century, the Birchand Swinnerton-Dyer Conjecture hasbecome one of the most notoriouslydifficult unsolved problems inmathematics, and has been listedas one of the seven million-dollar“Millennium Prize Problems” ofthe Clay Mathematics Institute. In this talk, we describe theproblem in elementary terms, and the surprising and beautifulways in which it is related to several well-known openproblems in number theory. Despite the difficulties in solving it,there is actually quite a bit known now towards the conjecture.We will give a survey of what is known – including severalrecent advances – and, finally, what remains to be done!AMS-MAA JOINT INVITED ADDRESSThe Arithmetic of the SpheresThursday, August 6, 9:30 AM – 10:20 AMMarriott Wardman Park, Salon 2/3Jeffrey Lagarias, University ofMichiganBeginning with historical remarks onthe harmony of the spheres, this talktours two topics at the interface ofnumber theory and dynamical systems.The first concerns the Farey tree, Fordcircles and the Minkowski questionmarkfunction. The second concernsFarey fractions, radix expansions and the Riemann zetafunction.MAA JAMES R. C. LEITZEL LECTURECalculus at CrisisSaturday, August 8, 8:30 AM – 9:20 AMMarriott Wardman Park, Salon 2/3David Bressoud, MacalesterCollegeThe predominance of calculus in highschool, recognition of the importanceof modeling dynamical systems—especially in the biosciences, andexistence of sophisticated onlineresources have changed what studentsneed from college calculus. Despiterecent insights into what it means to understand calculusand how students achieve this knowledge, failure rates areunacceptably high, and passing is no guarantee of abilityto use the ideas of calculus. Together, these forces confrontdepartments with a series of decision points around what toteach and how to teach it.AWM-MAA ETTA Z. FALCONER LECTURE“A Multiplicity All At Once”: Mathematics forEveryone, EverywhereFriday, August 7, 8:30 AM – 9:20 AMMarriott Wardman Park, Salon 2/3Erica Walker, Columbia UniversityWhat does it mean to learnmathematics? What does it meanto say that some people are “mathpeople”? In this talk, I draw upon20 years of research and teachingto describe multiple contextsfor mathematics learning andsocialization across the lifespan. Ishare findings from studies with elementary students, highschool youth, teachers, and mathematicians to describe howthey engage in mathematical practice, develop mathematicsidentities, and craft meaningful spaces for rich mathematicslearning. I discuss implications of this work for reframingteaching and learning, both within and outside of schools,to better foster people’s success, interest, and creativity inmathematics.#MAAthFestWashington, DC | August 5–8, 2015 13

It is common to associate number theory and discretemathematics with cryptography. However, problems tackledby NSA mathematicians actually draw upon a much broadervariety of fields including statistics, geometry, analysis,topology, graph theory, neuroscience, big data analytics,theoretical computer science, and computational linguistics.As a result, the research community at NSA includes experts ina wide range of mathematics and math-related subjects.The purpose of this session is to highlight both usual andunusual problems applied to national security, with all talksbeing at the general non-expert level. NSA mathematicianshave produced fascinating and significant results over theyears, however much of the work is not published. This sessionis a great opportunity for the MAA community to be exposedto some of NSA’s leading mathematicians and learn about theimportant role mathematics plays in a variety of problems.Carla D.

But the picture of mathematicalmodeling that applied mathematics researchers have is verydifferent from the word problems provided in textbooks forteachers. This session is dedicated to closing the gap betweenapplied mathematics research, mathematics educationresearch, and what goes on in classrooms around the UnitedStates. With an eye to creating environment(s) that supportstudents and teachers in mathematical modeling throughoutthe United States, at all mathematical and economic levels:How can we improve teacher’s and students understanding ofmodeling research, and improve access to the experience ofmathematical modeling research to populations that do nottypically receive graduate training in the field?Carlos Castillo-Chavez, Arizona State UniversityCarlos Castillo-Garsow, Eastern Washington UniversitySpeakersSara Del Valle, Los Alamos National LaboratorySherry Towers, Arizona State UniversityPatrick W.

Most recent advances rely on the connections betweenalgebra, homological algebra and knot theory. Examplesinclude the Jones polynomial, topological quantum fieldtheories, skein modules of links in 3-manifolds, Khovanov linkand Heegard-Floer homologies, homology of distributivestructures (i.e. quandles, racks, distributive lattices) andYang-Baxter operators, as well as categorifications of knotpolynomials and other appropriate combinatorial structures.These new developments relate knot theory to other branchesof mathematics including number theory, Lie theory, statisticalphysics, etc, and employ tools far beyond the traditional onesfrom algebraic topology. These ideas mark the beginningof a new era in knot theory that includes relationships withfour-dimensional problems and the creation of new forms ofalgebraic topology relevant to knot theory. Moreover, knottheory has numerous results and open problems requiring onlyknowledge of linear algebra, and are therefore accessible toundergraduates. We propose to bring together students andfaculty active in these areas to share them with the broadermathematical community and encourage future collaborationand investigation.Alissa Crans, Loyola Marymount UniversitySpeakersLou Kauffman, University of Illinois at ChicagoHeather Russell, Washington CollegeErica Flapan, Pomona CollegeAlissa Crans, Loyola Marymount UniversitySam Nelson, Claremont McKenna CollegeJ.

MAA MATHFEST 2015Themed Contributed Paper Sessions (continued)TCPS#9: What Can a Mathematician Do with a 3DPrinter?Saturday afternoonThis session is dedicated to the intersection of 3D printingand mathematics: the creation of objects through theapplication of college-level mathematics or research-levelmathematics, or the incorporation of 3D printing into theteaching of mathematics. In terms of the creation of objectson a 3D printer, of particular interest are those works thatanswer the question, “What can a mathematician do with a3D printer?” This may include fractal images, knots, smoothmanifolds, polyhedra, and demonstrations of theoretic orhistorical constructs. For teaching, of particular interest is theincorporation of 3D printing into college-level courses likegeometry, topology, or multivariable calculus.Edward Aboufadel, Grand Valley State UniversityLaura Taalman, James Madison UniversityTCPS#10: The Scholarship of Teaching andLearning in Collegiate MathematicsWednesday afternoonIn the Scholarship of Teaching and Learning (SoTL), facultybring disciplinary knowledge to bear on questions ofteaching and learning and systematically gather evidence tosupport their conclusions. Scholarly work in this area includesinvestigations of the effectiveness of pedagogical methods,assignments, or technology, as well as probes of studentunderstanding. The goals of this session are to: (1) featurescholarly work focused on the teaching of postsecondarymathematics, (2) provide a venue for teaching mathematiciansto make public their scholarly investigations into teaching/learning and (3) highlight evidence-based arguments for thevalue of teaching innovations or in support of new insightsinto student learning. Appropriate for this session arepreliminary or final reports of post-secondary classroombasedinvestigations of teaching methods, student learningdifficulties, curricular assessment, or insights into student (mis-)understandings. Abstract submissions should have a clearlystated question that was (or is) under investigation and shouldgive some indication of the type of evidence that has been (oris being) gathered and will be presented.

MAA MATHFEST 2015Themed Contributed Paper SessionsTCPS#11: Cultivating Critical Thinking throughActive Learning in MathematicsThursday morning and afternoonCritical thinking is self-directed, self-disciplined, selfmonitored,and self-corrective thinking. It entails effectivecommunication and problem solving abilities. “We thinkcritically when we have at least one problem to solve. Oneis not doing good critical thinking, therefore, if one is notsolving any problems.” (Richard Paul, Think Magazine, 1992).Mathematics is solving problems. The session will focus onthe role of active learning in mathematics, and how a teachercan use it to cultivate critical thinking. We invite instructorsto share their experiences and provide useful tips and trickson implementing active learning strategies and overcomingobstacles to active learning in general. Examples and ideascan come from any type of course, from undergraduate nonmajorservice courses and early-major mathematics coursesto late-major and even graduate-level classes. Speakers areencouraged to include assessment data on the effectivenessof their active learning strategies or empirical feedback fromstudents and/or faculty about their strategies.David Taylor, Roanoke CollegeRobert Allen, University of Wisconsin, La CrosseLorena Bociu, North Carolina State UniversityTCPS#12: Improving Undergraduate Math WritingWednesday afternoonFrom the simplest modeling equations to the most complex proofs,students often lack the writing abilities to properly communicatetheir solutions. In order to help students achieve coherentarguments that are both logical and sequential, math-writingskills need to be developed. Students in introductory math classesmust be able to find the solution to a problem by writing downall the necessary steps and reasons for each step leading up tothe answer. Students in advanced math classes must be able todelineate hypothesis from conclusion in proving statements andbe able to use the definitions, assumptions, and related resultsaccurately in justifying their proofs. In this session, we inviteparticipants to share useful approaches to teaching students notonly how to reason critically, but also to communicate in writingin a way that fully demonstrates conceptual understanding. Weencourage instructors that actively practice mathematical writingWe areTwo Sigma.We find connections in all the world’s data.

MAA MATHFEST 2015Themed Contributed Paper Sessionsacross all levels of the curriculum to share best practices forstudent writing objectives. We are interested in hearing aboutspecific problems and/or projects, as well as the assessmenttools for these projects, which have been used to address theissue of writing mathematics.Kerry M. Luse, Trinity Washington UniversitySita Ramamurti, Trinity Washington UniversityTCPS#13: Successful STEM Programs forElementary Education MajorsThursday afternoonAs President Obama stated regarding STEM, “We need tomake this a priority to train an army of new teachers in thesesubject areas.” In response to this need, many institutions havedeveloped programs that provide STEM certification or othercredentialing for pre-service elementary education majors.This session solicits presentations regarding programs thathave been developed to provide this type of credentialing. Asmathematics plays a significant role in these programs, themathematical aspects of these programs should be highlighted.Presentations about programs under development are alsoencouraged.Timothy W. Flood, Pittsburg State UniversityKarla Childs, Pittsburg State UniversityAaron Flood, Missouri University of Science and TechnologyTCPS#15: Democratizing Access to AuthenticMathematical ActivityFriday afternoonEssential to the learning of mathematics is that students engagein “authentic” mathematical activity, or what mathematicianswould recognize as “doing math.” However, too often deficitexplanations (i.e., students’ lack of background knowledge,lack of math ability, lack of motivation) have been used todeny students access to authentic experiences. This sessionis a vehicle to promote a more equitable orientation to thelearning of mathematics for all students in a range of learningsituations (not just the “top” kids in ideal situations). We invitetalks illustrating viable, evidence-based strategies that promoteaccess to authentic mathematical activity through inquiry thathonors the diversity of students’ mathematical knowledge.Topics may include 1) innovative, equity- and inquiry-orientedmethods of teaching and learning in remedial, developmental, orintroductory courses and courses for non-majors; 2) lessons thatallow students to use mathematics to address important equityand social justice issues in their communities; and 3) programsthat provide students with opportunities to engage in the kindsof authentic mathematical activities and research projects thatembrace the knowledge and experiences they bring to school.Catherine Buell, Fitchburg State UniversitySteven Greenstein, Montclair State UniversityZahava Wilstein, Berry CollegeTCPS#14: Projects, Applications andDemonstrations to Enhance a Numerical Analysisor Computational Mathematics CourseSaturday afternoonComputational mathematics is an important subject that is eitheran independent course or a component across multiple courses.This session seeks to gather ideas and further the scholarlydiscussion regarding the delivery of a course in: numerical analysis,numerical methods, modeling, and the use of Computer AlgebraSystems to solve problems. All applicable ideas are welcome, butwe would like to encourage presentations in areas like:• New techniques for presenting numerical methods to anundergraduate audience• New resources or tools that can be incorporated into acourse• Applications that illustrate the power of computationalmathematics• Contemporary research that is accessible toundergraduate students• Assessment tools that could be used in this type of courseKyle Riley, South Dakota School of Mines & Technology#MAAthFestWashington, DC | August 5–8, 2015 23

MAA MATHFEST 2015Themed Contributed Paper Sessions (continued)TCPS#16: Curriculum Development to Support FirstYear General Education Mathematics StudentsWednesday afternoonA common focus of university administration is studentretention and graduation. First year mathematics coursesremedialand general education- have relatively high drop/fail/withdraw rates, which place them under scrutiny byadministration. In this session, we would like to hear whatyou have been doing to improve pass rates and studentpersistence in first year courses with traditionally high DFWrates. We hope to focus on department efforts (rather thanspecific classroom approaches) to support students in thesefirst year Mathematics courses. Presentations could includecomplete multi-section redesign, restructure of curriculum,efforts to standardize. We would like to hear about successful,in progress, and unsuccessful efforts. Presentations with adescription of the initiative along with data supporting thesuccess or failure are encouraged.Donna Flint, South Dakota State UniversityCharles Bingen, University of Wisconsin Eau ClaireTCPS#17: Curriculum and Course Development toSupport First Year STEM StudentsFriday afternoonPoor retention in the STEM fields is often tied to students’ initialdifficulties and/or lack of motivation in mathematics coursesearly in their academic career. In this session, we would liketo hear about efforts to help struggling students in first yearmathematics courses for STEM students or to help motivatestudents in these courses. We are particularly interested indepartmental efforts, rather than specific classroom teachingactivities. We would like to hear about successful, in progress,and unsuccessful efforts. Presentations with a description ofthe initiative along with data supporting the success or failureare encouraged.Donna Flint, South Dakota State UniversityDan Kemp, South Dakota State UniversityCharles Bingen, University of Wisconsin Eau ClaireTCPS#18: Using Modeling for Teaching DifferentialEquations: Before, During, AfterSaturday afternoonOften modeling is associated with differential equationscourses as a motivator for learning and as a way of showinghow mathematics is applied in other disciplines such asphysics, biology, and economics. Modeling can be used (1)as a way of leading up to the mathematics being taught, (2)during the instruction on the mathematics and techniques,and/or (3) after the mathematics has been taught. These threetimes—before, during, or after—for using modeling have thepotential to support students and motivate their learning. Weinvite colleagues who use modeling, especially with real data,to share their experiences with special attention paid to thetiming of the modeling activities with respect to associateddifferential equations concepts and techniques. This sessionis sponsored by SIMIODE - Systemic Initiative for ModelingInvestigations and Opportunities with Differential Equationsand presenters will be invited to submit their modelingscenarios for peer-reviewed publication at www.simiode.org.Brian Winkel, United States Military AcademyKaren Bliss, Quinnipiac UniversityJessica Libertini, Virginia Military InstituteNakeya Williams, United States Military AcademyTCPS#19: Innovative Approaches in the CalculusSequenceFriday and Saturday afternoonsThere has been a significant amount of investigation intothe flaws of traditional calculus courses and possibleimprovements, from the Calculus Reform movement beginningin the late 1980s to the recent MAA study finding significantattrition during the calculus sequence. This session shinesa spotlight on recent efforts from instructors to make aproductive change. In this session, we ask instructors to sharecreative ideas for instruction from the calculus sequence.We are interested in general approaches and/or specificactivities that a) help students engage in the mathematics ofcalculus in innovative ways and/or b) promote group workand conversation about the mathematical content. Submittedabstracts should include a description of the approach/activity, how it meets these objectives, and observed strengthsand weaknesses compared with the traditional approach. Weencourage presentations in which the audience can experiencethe innovative teaching and learning.Aaron Wangberg, Winona State UniversityBrian Fisher, Lubbock Christian UniversityJason Samuels, City University of New York24 Washington, DC | August 5–8, 2015 #MAAthFest

MAA MATHFEST 2015Themed Contributed Paper SessionsTCPS#20: Evidence Based Approaches to theMathematical Preparation of Secondary TeachersWednesday afternoonThe mathematical preparation of secondary teachershas received substantial attention by mathematicians andmathematics teacher educators for many years, but how douniversity instructors and program coordinators know theirefforts are making a difference? While the program evaluationprocess, which can include accreditation reports (e.g., CAEP)and teacher candidate surveys, encourages faculty to seriouslyconsider this question, it is tempting to focus program evaluationon outcomes such as: graduation rates, teacher placement rates,and scores on teacher licensure exams or performance-basedteacher assessments (e.g., edTPA). In this session, we invitemathematics content and methods instructors and programcoordinators to share ways they gather and analyze datafor the purpose of making decisions about their programs.Presentations should focus on one or two program goals directlylinked to the mathematical preparation of secondary teachers.Examples include: How do you know that teachers can promotemathematical thinking and learning in ways consistent withthe Common Core Standards for Mathematics (NGA Center& CCSSO, 2010)? How is your program addressing therecommendations in the Mathematical Education of TeachersII document (CBMS, 2012)? How does your program workwith mentor teachers to develop candidates’ use of formativeassessment?Laurie O. Cavey, Boise State UniversityScott A. Courtney, Kent State UniversityTCPS#21: Show Me Geometry: GeometrySoftware and Tablet DemonstrationsWednesday afternoonThis session invites presenters to share demonstrations, usinggeometry software or tablet applications, which help studentsto understand aspects of undergraduate geometry. Thesedemonstrations should be suitable for Euclidean and non-Euclidean geometry courses as well as for courses frequentlyreferred to as “modern” or “higher” geometry but not thoserelated to differential geometry or (low-level) graduate courses.Presenters must perform the full demonstration (or a key portionof it) and discuss the aspects of the demonstration that helpstudents to understand an associated theorem. Informationregarding prerequisite topics and related areas with whichstudents have difficulty should be discussed as should problems,if any, experienced in using the software or tablet application.Presenters are invited to discuss how they have modified thedemonstration over time as well as to share information aboutsoftware or tablet explorations performed with students that havehelped students understand the associated theorem. Abstractsshould include the name of the software or application, theplatform (computer or tablet), and the associated theorem aswell as a brief description of the demonstration. Presenters mustprovide their own laptop or tablet.Sarah L. Mabrouk, Framingham State University#MAAthFestWashington, DC | August 5–8, 2015 25

Welcome toDiscoverMathCircles!Math Students’ Circles and Math Teachers’ Circles bring K-­‐12 students or K-­‐12 mathematics teachers together with mathematically sophisticated leaders in an informal setting, after school or on weekends, to work on interesting problems or topics in mathematics. Math Circles combine significant content with an interactive setting that encourages a sense of discovery and excitement about mathematics through problem solving and exploration.

A Discussion of the MAA/NCTM JointPosition Statement on CalculusWednesday, August 5, 4:10 PM – 5:30 PMMarriott Wardman Park, Delaware AIn 2012, members of the MAA and NCTM released a jointposition statement on calculus. The goal of the statement isto provide a clear vision of how calculus instruction shouldoccur given that is the course most students planning to entermathematically intensive careers take as they exit secondaryschool and/or again as they enter college. The increase instudents taking calculus in secondary schools across the UShas had several unwanted effects including students with aninadequate foundation in algebra, geometry and trigonometryand enrolling in calculus multiple times (secondary school andcollege), basically repeating the course. Although calculus canplay an important role in secondary school, the ultimate goal ofthe K–12 mathematics curriculum should not be to get studentsinto and through a course in calculus by twelfth grade but tohave established the mathematical foundation that will enablestudents to pursue whatever course of study interests them whenthey get to college. The college curriculum should offer studentsan experience that is new and engaging, broadening theirunderstanding of the world of mathematics while strengtheningtheir mastery of tools that they will need if they choose to pursuea mathematically intensive discipline. Representatives from theMAA and NCTM will discuss the statement, the background fordeveloping the statement and recommendations for the design ofcalculus programs at the post-secondary level recognizing thedifferent backgrounds and goals of potential students.Organizer:Jessica Deshler, West Virginia UniversityPanelists:David Bressoud, Macalester CollegeMichael Boardman, Pacific University

What Mathematics Do EngineeringStudents Need to Know in the First Two Years?(And What If It Doesn’t Start with Calculus?)Thursday, August 6, 2:35 PM – 3:55 PMMarriott Wardman Park, Salon 1Mathematics is an essential component of the education offuture engineers, but what mathematics do engineers need toknow, when should they learn it, how will they learn it best, andwhat role does mathematics play in attracting and retainingstudents in engineering? A recent longitudinal (10-year)study on the success of Wright State University’s innovativeengineering curriculum, which (gasp!) does not start with thestandard calculus sequence, offers an innovative example ofhow we might re-imagine a modern mathematics/engineeringcurriculum partnership. Panelists will discuss the Wright Statemodel and other trends in engineering education that mightaffect mathematics curricula and will highlight what welearned about the mathematical needs of engineering studentsfrom the MAA’s Curriculum Foundations Project. Given theengineering community’s influence on the calculus curriculum,we all have a vested interest in this conversation – whetheror not we teach future engineers.

Heavenly Mathematics: The Forgotten Art ofSpherical TrigonometryPart A:Wednesday, August 5, 3:30 PM – 5:30 PMOmni Shoreham Hotel, Hampton RoomPart B:Friday, August 7, 3:30 PM – 5:30 PMOmni Shoreham Hotel, Hampton RoomTrigonometry came into being at the birth of science itself,merging Greek geometric models of the motions of celestialbodies with the desire to predict where the planets will go.With the sky as the arena, spherical trigonometry was the “bigbrother” to the ordinary plane trigonometry our children learnin school. We shall explore the surprisingly elegant theorythat emerges, as well as its appropriation into mathematicalgeography motivated by the needs of Muslim religiousritual. The beautiful modern theory of spherical trigonometry(including the pentagramma mirificum), developed by JohnNapier along with his logarithms, leads eventually to anastonishing alternate path to the subject using stereographicprojection discovered only in the early 20th century. Weconclude with a consideration of some of the ingenioustechniques developed by navigators in the 19th century to findtheir locations, using as data only a couple of observations ofstellar altitudes.Glen Van Brummelen, Quest UniversityJoel Silverberg, Roger Williams University#MAAthFestWashington, DC | August 5–8, 2015 33

MAA MATHFEST 2015K-12 ActivitiesIndustrial Math Research in the PICMath ProgramSaturday, August 8, 1:30 PM – 5:00 PMMarriott Wardman Park, Maryland BDuring the spring 2015 semester,mathematics undergraduate students at30 U.S. universities and colleges wereenrolled in a PIC Math (Preparationfor Industrial Careers in MathematicalSciences) research course. Each studentteam worked on its own researchproblem, which came directly fromindustry, and submitted a written reportand video solution to the problem.Several students with exemplarysolutions will discuss their problem andsolution during this session. In addition,other students will give posterpresentations of their work. Finally,a few industrial mathematicians willmake presentations about math in BIG(business, industry, and government).PIC Math is a program of the MAAand SIAM supported by NSF funding(DMS-1345499). See www.maa.org/picmath.Organizers:Linda Braddy, MAAMichael Dorff, Brigham YoungUniversitySuzanne Weekes, WorcesterPolytechnic InstituteReza Malek-Madani, United StatesNaval AcademyThe MAA strives to ensure that sessions at MathFest presentmathematics in a way that is accessible to a broad audience.As a result, K-12 teachers will find all the expository sessionsat MathFest to be informative and enriching. In addition, thefollowing sessions are directed specifically at the professionalinterests of K-12 teachers.Register for the AMC 8 or AMC 10/12 Contest(s), and you’reautomatically enrolled as a K-12 Teacher Member.

He thereby thought he had proventhe existence of God! James Tanton doesn’t claim to be sobold, but he is willing to prove instead that one equals two.And, moreover, just to convince you that he is right, he willdo so a dozen times over, drawing upon a wide spectrumof mathematical techniques: school algebra and arithmetic,probability and mechanics, pure thought and physical action!Will you be able to find fault with any of his “proofs?” Thiswill be a math talk of the like you’ve never seen before.
