The Parrot's Theorem

Parents and teachers should urge their high school to include The Parrot's Theorem by Denis Guedj in their high school summer reading programs and if possible, into the secondary math curriculum.  The book, through an interesting story and a survey of the history of mathematics, could help students become more engaged with a topic that can be hard to access for some people.  This book could help students think more about math through the context of history and make emotional connections to characters in the story.  These connections could make material taught during the school year more interesting and meaningful.  The book could be used as an introduction to high school math for rising freshmen, or could be used as an ongoing reference point for students as they learn about the mathematical topics over their educational career.  Developing mathematical literacy and interest outside of the traditional classroom setting and through different modes of representation could prove valuable for students in their high school career and beyond.  The book demonstrates learning in fun and novel settings, and even includes a number of techniques that can help teachers in their work.

The book follows a family after the arrival of a mysterious letter from a long lost friend, and, a few days later, his extensive library of mathematical texts.  The characters explore the library and search for clues to the origin and meaning of the letter.  The Parrot’s Theorem presents this history in three distinct eras, divided by time period and geographic area.  The three periods given are Ancient Greece 700BC-700AD, the Arab world from 800-1400AD, and in Western Civilization from 1400- present (p. 49).  Within these broad eras, the book explores the work of a number of mathematicians from each era, as part of a growing continuum of knowledge.  The narrative, linear presentation of the history of math in The Parrot’s Theorem acts as a survey of math history.  The nature of a historical survey is that topics are covered with less depth than may be desired, but The Parrot’s Theorem, primarily a novel, does not attempt to portray all of math’s history.  The book can be considered as an introduction to history rather than an exhaustive source.  The narrative structure of the book does, however, provide some insight on the teaching of math from a historical viewpoint.

One of the largest challenges teachers face, especially in mathematics, is student engagement.  Student engagement is demonstrated through excitement, curiosity and passion for the work students do in the classroom.  Engaged students work harder and excel in their studies.  There are many techniques that can be used to foster student engagement, and specific examples can be seen within the text of The Parrot’s Theorem, and even more techniques can be extrapolated from the book.  In addition to the teaching styles and techniques used by the characters in The Parrot’s Theorem, the book itself could provide students with additional access points and personal connections to the study of mathematics.  Using a blend of history and narrative, the book could be beneficial for students and teachers if used in a proper context.

The book can be used as a way to better engage students.  Math can present different challenges for student as compared to other subjects.  In the sciences, students are formally learning about the rules that govern the world they live in.  They understand and can observe different concepts they learn in biology or chemistry.  In history class, students can understand the connection between their own lives and the subjects they studied.  Often times, they can visit the locations of the important moments of history.  There can be an emotional connection to characters from the great works studied in an English class.  Math can present a challenge for teachers looking to improve their student’s engagement in class, because at times, the material can seem disconnected from the lives of students.  It can lack an emotional, personal or observable connection for students, leading to a disinterested approach in class.  In order to forge this type of connection, The Parrot’s Theorem could be used by teachers as part of their curriculum.  The book presents a mysterious story centered on characters that are high school aged, and the core of the book concerns the history of mathematics.  In a way, the book uses a story about a mysterious letter and a library of books as a “Trojan Horse” for teaching some diverse mathematical concepts.  There are a few reasons using this book as part of a classroom curriculum could be effective.  First, for students who excel at other subjects, but who may do worse in math, this could present a different method of taking in a lesson on math.  Students have a variety of learning styles, and presenting math in an original way could connect them to material they had struggled with in the past.  The novelty of reading a book about math and discussing mathematical ideas, rather than another lecture or worksheet, could really work for students.  Additionally, students reading the book may benefit from the dynamic nature of mathematics presented in the story.  Throughout the book, Mr. Ruche and his students discuss the three big questions that had stumped mathematicians since ancient Greece: Squaring the Circle, Duplicating the Cube, and Trisecting an Angle.  Mr. Ruche discusses numerous men and women who tried to solve these problems over the years.  Eventually, we find that these problems cannot be solved geometrically.  While all these mathematicians all eventually failed to solve these particular problems, each had a different mathematical perspective that would change how later mathematicians would view the same problems.  Students may emotionally connect with this idea of mathematical tradition and how even the greatest minds in history, like Pierre de Fermat and Blaise Pascal, had math problems they could not solve.  Students could come to understand that learning math is a process that includes failure, even for the most brilliant minds.

As we see in The Parrot’s Theorem, there are multiple instances of mathematics as a disruptive force.  We see Greeks reject the notion of irrational numbers and negative numbers, both of which are now common parts of our education.  In the historical portions of the book, we see mathematicians as dangerous figures, being exiled and jailed.  In the plot of the novel, we see Mr. Grosrouve, who puts himself in mortal danger to both acquire mathematical texts, and to keep his proofs from being published or stolen.  These examples, where mathematicians may be jailed or worse for presenting ideas may also connect with students.  Defiance and rebellion are ideas rarely discussed in mathematics, and especially for teenagers, acknowledgment of these feelings could change the way they approach mathematics.  The book also has its own rebellious spirit.  Although there is little explicit mention of this, the book seems to have a relatively negative view of modern formal math education.  All the lessons Mr. Ruche gives to his students are outside of a classroom, and instead take place in either the home library, or a number of public libraries in Paris.  The twins, who are secondary school students, mention their schooling only briefly, and casually skip a day’s worth of lessons after a late night in the library.  These characters, as well as the defiant mathematical figures from history, could place the study of mathematics in a different perspective for students who may find their past math classes to be dry or dull.    

In addition to the lessons for students, The Parrot's Theorem provides some lessons for teachers.  If we consider Mr. Ruche, the central figure of the story, to be a teacher, and the family that he lives with his students, we can see numerous teaching methods employed to improve student engagement.  Doug Lemov’s Teach Like a Champion presents a teaching technique idea called “The Hook”.  Lemov describes a hook as “a short introductory moment that captures what’s interesting about the material and puts it out front” (p. 75).  The hook is used as the first step to get students interested in a topic.  In the Parrot’s Theorem, Mr. Ruche employs a few different hooks to interest his students.  For example, on Page 99, he and the youngest child, Max, set up the library to feel like the Great Library of Alexandria using sounds, smells, and props.  Mr. Ruche then further sets the scene by telling the story of how the city came to be the center of the academic world under Ptolemy.  By creating this environment, Mr. Ruche gives a great example of using a hook in a classroom.  He is teaching a lesson on mathematics, but grabs the attention of his students by transporting them to a different time and place.  We can see that using these techniques, Mr. Ruche has engaged his students in the material.  As the story progresses, the older siblings, Jonathan and Lea, start taking over the research that Mr. Ruche has been doing.  In a way, this can be seen as scaffolding.  Mr. Ruche first leads the lessons, telling his class what he did to discover the material for the lesson.  As the students became more and more comfortable, Mr. Ruche allowed the students to take on more of the research and drive the learning, eventually teaching Mr. Ruche about certain topics.    
            
There would be some challenges presented by including the book as part of a secondary mathematics course curriculum.  The book covers nearly all of Western mathematical history, and as such presents a problem in classes that focus exclusively in a given topic, like geometry or calculus.  The novel may cover too much history for a single class to cover.  The book could work better as a culminating project for students who are completing their high school careers, or as a primer for students just entering high school.  The book could alternatively be used as a form of differentiated assessment.  Rather than demonstrate their knowledge through more traditional means, like tests and quizzes, students could be given the option to research a mathematician they find particularly interesting from the book.  Based on the person they select, a teacher could provide an appropriate mathematical assignment related to the work of their subject.  This could work as a long term assignment, like creating a lesson like Mr. Ruche creates, or as an anchor activity students would work on throughout the length of a course.  The book could also be used as a reference across a math department.  Some historically minded students may become more interested and engaged for a lesson when they know where the work falls in time, whether its geometry from the days of Pythagoras or calculus from Newton’s time.
            
The Parrot’s Theorem presents a survey of western mathematical knowledge, and acts as an entry point for further inquiry for more curious learners.  The book presents some alternative teaching techniques, and provides stories and history to spark the curiosity of students.  The book could help both educators and math students in numerous ways at the high school level.  Whether as a summer reading book, or as part of a curriculum, or even as a student career long point of reference, the book provides a new and exciting approach to thinking about math inside and outside of the classroom.
