Math is Uplifting

Screen Shot 2017-08-11 at 12.52.14 PM

Last week as teachers returned to school for faculty in-service, the school where I teach (Regents School of Austin) offered several talks/presentations that were broadly labeled as “Classical Christian Development.” There was a talk on western civilization, a talk on the importance of story, a talk on the centrality of theology, and a talk on math. I was asked to give the talk on math and this post is acting as a summary/recap. You can click the image above to download the slides I used in the presentation.

The title of my talk was “Math is _________ .” In introducing the talk I let that title just linger there for a while, asking the audience to consider what words or phrases come to their mind for filling in the blank. As the speaker I also enjoy soaking in the facial reactions of each member of the audience when it is announced that this next 45 minute talk will be about math. I contend that 100% of people (and as a statistics teacher, it means something when I say 100%) have a memorable, visceral experience from a math class. There are no neutral expressions on the faces of audience members. The sad thing from my perspective as a math teacher is that the majority of those memorable experiences are negative. My hope in giving this talk was to encourage people to consider some new words for the blank that they maybe had not thought of before.

I start by offering some familiar suggestions for the blank (familiar at least to our Classical Christian context where we teach). Here is the mission statement of Regents School of Austin:

The mission of Regents School is to provide a classical and Christian education, founded upon and informed by a Christian worldview, that equips students to know, love and practice that which is true, good and beautiful, and challenges them to strive for excellence as they live purposefully and intelligently in the service of God and man.

The bold emphasis is mine to point out a few words that might fit in the blank.

Math is TRUE.  This isn’t something I need to sell people on. I mean, 2 + 2 = 4 every time, amirite? To take it a step further though, I encouraged people to consider some ideas I put forward in another post: God, Math, and Order.

“To all of us who hold the Christian belief that God is truth, anything that is true is a fact about God, and mathematics is a branch of theology.”

~ Hilda Phoebe Hudson

When discussing mathematics from a Christian perspective, one statement that always seem to bubble to the top of the conversation is that mathematics reveals God as a God of order. This is true. This is also way underselling the connection between God and math.

Does God use mathematics because He is a God of order or does math have order because God uses it? I would argue that order is not a characteristic God displays but a quality that He defines by His nature and math gives us a glimpse into that nature. “Our God is a God of order” – By this claim we shouldn’t merely mean that God acts in an orderly fashion. We should mean God defines what an orderly fashion is. Order is not a quality God decided to portray, rather order flows from His nature.

If this can become our perspective, then when we speak of mathematics portraying God as a God of order, that description will carry so much more meaning. Instead of just correlating our mathematical results with some quality that God displays, we can realize those results are better understood as a manifestation of God’s nature. In a way we are communing with Him in our work as mathematicians, gaining deeper insight into His character.

Math is BEAUTIFUL. This is another category that I don’t have to do much convincing on. So many people have put together so many amazing presentations on the beauty of mathematics that any rational person could be convinced of math being beautiful after a quick Google search. Here is one my favorite videos in this regard and a few quotes.

“The mathematician’s patterns, like the painter’s or the poet’s, must be beautiful; the ideas, like the colors or the words, must fit together in a harmonious way. Beauty is the first test: there is no permanent place in the world for ugly mathematics.”

~ G.H. Hardy, A Mathematician’s Apology

“The mathematical sciences particularly exhibit order, symmetry, and limitation; these are the greatest forms of the beautiful.”

~ Aristotle

Math is GOOD

Here is where the sell gets a little harder. As I mentioned above, a lot of people associate very negative things with math class. When asked to complete the phrase “Math is _________” they may think of words like “stressful,” “confusing,” “too abstract,” “not applicable to me,” or “the exact opposite of all that is good and holy.” Here is where I focused the remainder of my talk in an attempt to get anyone who fell into this boat to start seeing math in a different way.

Whenever I am presenting at conferences I like to do the following exercise: I ask people what the number one question asked in math class is, and without fail I always hear back “when am I ever going to use this?” The reality is that this is not a question, it is a statement. It is a statement of confusion and frustration. In other words the answer to “when am I ever going to use this?” has already formed in the student’s mind as “I am never going to use this” and then they withdraw from the mental activity at hand.

I would argue that what a student is really asking is “why should I value this?” It is not a question of finding application but of finding meaning. Maybe another rephrasing would be “why is this worth learning?” As Christian educators this deep longing should be familiar. If we believe Augustine in the Confessions that “Thou hast made us for thyself, O Lord, and our heart is restless until it finds its rest in thee,” then that doesn’t stop when students walk into math class. The most fundamental thing that is happening in math class is that students are seeking value (something we as teachers need to address in our curriculum) and are seeking to be valued (something we as teachers need to address in our pedagogy). In other words, the foundational issue of math class is an affective one as opposed to a cognitive one.

Affective issues are just present for students but for teachers as well. Another exercise I do at conference presentations: I ask people to close their eyes an imagine their best/ideal teaching moments (the O Captain My Captain moments). I then ask volunteers to share a word or phrase that describes that moment. Not once in all my years of doing this has a teacher mentioned anything about content. The language that is used is always affective – “engaging,” “curious,” “joyful.” Don’t get me wrong – I know the content was still there in the lesson and probably operating at a high level to produce those affective moments. The point of the exercise is simply to illuminate how central issues of affect are to the math classroom.

This is not just an anecdotal observation, but it is also affirmed in educational research:

When teachers talk about their mathematics classes, they seem just as likely to mention their students’ enthusiasm or hostility toward mathematics as to report their cognitive achievements.

Similarly, inquiries of students are just as likely to produce affective as cognitive responses, comments about liking (or hating) mathematics are as common as reports of instructional activities.

Affective issues play a central role in mathematics learning and instruction.

~ Douglas McLeod in Handbook of research on mathematics teaching and learning (1992)

It is also affirmed in national policy documents on math education (even though those documents never really develop how to go about obtaining these stated results – hence the motivation for my dissertation).

“Being mathematically literate includes having an appreciation of the value and beauty of mathematics as well as being able and inclined to appraise and use quantitative information.”

~ NCTM Standards for Teaching Mathematics

“Mathematical proficiency has five strands: conceptual understanding, procedural fluency, strategic competence, adaptive reasoning, and productive disposition. Productive disposition is the habitual inclination to see mathematics as sensible, useful, and worthwhile.”

~ Adding it Up: Helping Children Learn Mathematics (National Research Council)

OK – so students and teachers both would admit that affect plays an important role in math education, this is supported by research, and it is affirmed in national policy documents and recommendations. With all of this motivation how are we (math teachers) doing?

As it stands our current methods of teaching mathematics are producing untold numbers of students who see mathematics more about natural ability rather than effort, who are willing to accept poor performance in mathematics, who often openly proclaim their ignorance of math without embarrassment, and who treat their lack of accomplishment in mathematics as permanent state over which they have little control.

~ McLeod (1992)

This quote may seem a little dated as far as research goes but I think it perfectly sums up the situation. No matter how dated the quote is, I know this is still true today because… well, I’m a math teacher. Plus I introduce myself to people in social situations. Other math teachers will quickly confirm this: whenever you meet someone and they ask “what do you do?” and you respond “I teach math” the next response will typically be something like “I was never any good at math.”

Math teachers are probably second only to priests in terms of the number of confessions we take from people.

Also, through these conversations it gets revealed that what these people really didn’t like about math were more factors of the math classroom schooling environment than the discipline of math itself. To me though, these actions are very foreign to the actual discipline of mathematics. For instance, people might say “I hated memorizing all of those formulas.” No mathematician would describe math as memorizing formulas. In essence what these people are doing is gossiping about math.

It as if they are saying “My friend’s cousin’s roommate’s teacher said that math is a jerk. He saw math behind the bleachers making out with history behind science’s back. No thank you – I want no part of math.”

To which I’d have to say “First, math is everywhere so math is probably making out with all of the subjects. Second, have you actually met math? Maybe you should talk to math face to face to sort this out.”

I think people have this false perception of what mathematics is because their experience of the math classroom was through forced, awkward, artificial “relevance” of math topics. For example:

Screen Shot 2017-08-11 at 2.25.10 PM

The previous day another teacher had shared a story of how he actually jumped a cow in his car and miraculously survived – so I turned it into a word problem. Like most word problems it successfully takes and interesting event/story and kills it dead by now making it a chore for students to slog through. The artificial relevance of this problem makes it seem as if Mr. Williams was in the car doing this:

alan-blackjack-o

(NOTE: prior to this example coming up, I had planned to share an example I saw in a textbook of calculating parabolic motion on Steph Curry’s jump shot – this is clearly mathematical but we have to be careful not to oversell relevance as if Steph Curry makes his shots because he knows the math).

So how do we avoid this artificial relevance? How do we teach math differently at Regents? Because we teach at a Christian school, does that mean 2 + 2 = Jesus now? Here I had to share some thoughts from another previous post: 2+2=Jesus? Ultimately this type of question fails to see math as anything more than calculations. Math has calculations, but it is more than that. The question also sees Christianity as simply a new way of thinking (Jesus is now the answer to everything). As a pastor of mine would always say:

Christianity is always more than thinking, but never less.

~ Neil Tomba, Senior Pastor, Northwest Bible Church, Dallas, TX

A better understanding of how Regents approaches math differently can be summed up in the following quote:

“If you want to build a ship, don’t drum up people to collect wood and don’t assign them tasks and work, but rather teach them to long for the endless immensity of the sea.”

~ Antoine de Saint-Exupery

I pulled this from the first page of A Mathematician’s Lament, by Paul Lockhart, and it hits on the deeply affective aspect of what we do as teachers. I also proceed to read the opening imagery of Lockhart’s initial paper to communicate to everyone in the audience how we as math teachers feel about what often is described as math teaching.

So how do we go about cultivating mathematical affections? Well, I’ve written a lot about that here, but to quickly summarize:

Education is not primarily a heady project concerned with providing information; rather, education is most fundamentally a matter of formation, a task of shaping and creating a certain kind of people…. What makes them a distinctive kind of people is what they love or desire or value….. An education, then, is a constellation of practices, rituals, and routines that inculcates a particular vision of the good life by inscribing or infusing that vision into the heart (the gut) by means of material, embodied practices…. There is no neutral, nonformative education.

~ James K.A. Smith, Desiring the Kingdom (2009)

And also:

Mathematics educators who set out to modify existing, strongly-held belief structures of their students are not likely to be successful addressing only the content of their students’ beliefs…it will be important to provide experiences that are sufficiently rich, varied, and powerful in their emotional content.

~ G.A. Goldin in Beliefs: A hidden variable in mathematics education? (2002)

In other words, it is the practices of the math classrooms that shape mathematical affections. So I challenged the teachers in the audience to consider:

  • Students want to know your story…
  • What are the touchstone moments you can recall from a math classroom?
  • What would you say are the “thick” practices/routines/liturgies of a math classroom?
  • How has your experience of those practices shaped your perspective of mathematics?
  • In light of our own experience of mathematics how do we work to shape our students’ experience of mathematics? How do we cultivate their mathematical affections?

To help answer these questions, I closed by offering three new words to fill in the blank of “Math is ____________ .”

Math is INVITING

Here I got to share about my role as an ambassador for the Global Math Project. First, an introductory video:

I challenged people to tell me how this math problem was different than the cow-jumping math problem above. A couple of different responses: this one makes you curious – you want to solve it. This problem has no words only images. This problem makes you ask questions rather than asking them for you.

Often our invitation into mathematics is already excluding some students. The words or terminology we use to introduce the problem may already shut people down. I’m not saying we shouldn’t use proper terminology, I am just asking to consider if it is always necessary. For instance, this example is teaching binary numbers but that term is never used. We don’t start by telling students “Ok, let’s learn the properties of binary numbers.” We have this interesting video instead. I would rather students understand the underlying concepts and connections (which this video very clearly portrays) than parrot terminology without understanding.

Math is ANALOGY.

I have written elsewhere about Flatland: A project of many dimensions. I love Flatland, and occasionally you’ll even see it’s title referenced as a parable. I love taking students through the though process of what would it look like for a sphere to enter into the 2D world of Flatland. In Flatland the inhabitants would only see the sphere as a circular cross section, completely unaware of the concept of a 3D sphere outside their literal plane of existence.

In this way the concept of dimension in mathematics offers a great analogy for issues of faith. How can Jesus be both fully God and fully man? Well, maybe it is kinda like the sphere still being a sphere but also a circle. I also love the illustration put forward in the chapter on dimension in Mathematics Through the Eyes of Faith about what if a hand entered Flatland. As your fingers went into Flatland the inhabitants would see cross sectional circles, none of which are connected. But if they could zoom out to 3D space then they could see fingers all connected to one hand. Maybe this can help us understand how the church is composed of many separate members but is still referred to as one body.

Finally there is Salvador Dali’s Crucifixion (Corpus Hypercubus). Just as a 3D cube can unfold into a 2D net that appears like a cross, a 4D hypercube can unfold into the 3D net seen above. Dali is speaking of the mystery of the crucifixion – of something that originated in a higher plane of existence unfolding itself into our world. These moments of insight for our students are made richer by the use of math as an analogy for faith.

Math is SERVING.

I have written a lot here about service-learning in mathematics. I won’t expand here, I’ll just summarize why I think teacher’s should consider service-learning:

  • Affective learning objective is primary
  • Cognitive learning objective is still present and operating at a high level
  • Opportunity to communicate the value of affective learning outcomes through assessment
    • “It is through our assessment that we communicate most clearly to students which activities and learning outcomes we value.”
    • David J. Clarke, NCTM Assessment Standards for School Mathematics
  • Reflection is key
  • Moves toward inculcating a servant’s heart

Here is a quote from a student who would adamantly describe themselves as “not a math person” at the end of the year after going through a service learning project. When asked if they think their attitude towards math has become more positive:

“Yeah, definitely, much more positive. It was hard, don’t get me wrong and I’m not saying the ‘I’m no good at math thing’ didn’t change, but I do think … I am sure that I can learn it, because I am sure I can learn it. It just will take longer and when you don’t feel so completely discouraged about it … When you do feel that you do have shot to understand it and learn it, for me at least it really raises my attitude towards it. It doesn’t feel like it’s this hopeless thing that I just have to suffer through. It is kind-of just a hill you climb, right?”

I like this quote because it is honest. The point of cultivating mathematical affection is not to have every student now love math and have it be their favorite subject. The hope is that students who once saw math as this hopeless thing to be endured now see value in working hard at it. They start to see why they should value math.

Finally, returning to the Global Math Project as the inspiration for my talk in the first place:

Math is UPLIFTING.

I love that the motivation behind the Global Math Project is to change people’s experience of mathematics. I would love to see the students who would say that math is “confusing” and “stressful” now start to use words like “uplifting” to describe mathematics.

Returning to the Regents mission statement:

The mission of Regents School is to provide a classical and Christian education, founded upon and informed by a Christian worldview, that equips students to know, love and practice that which is true, good and beautiful, and challenges them to strive for excellence (inviting) as they live purposefully and intelligently in the service of God and man.

Notice the new points of emphasis. Sometimes focusing on math as true, good, and beautiful can still be an abstract exercise. Let’s start looking for math after the comma. Let’s look at the experience students are having of mathematics. Let’s care about the practices and liturgies of the math classroom so we can impact the mathematical affections of students.

If you are interested in starting the conversation with math (and leaving gossiping about math behind) I ended but sharing two great talks given by Francis Su, former president of the Mathematical Association of America:

Using Math to Fight Homelessness

(From Arches, a magazine published by Regents School of Austin)

AP Statistics student Vanessa Aguirre shares how their class harnessed the power of surveying, statistics and service to help the Mobile Loaves & Fishes ministry in their efforts to combat homelessness in Austin.

On a rainy Tuesday morning, the thirty-six AP Statistics students walked through the Community First! Village of Mobile Loaves and Fishes, a local Austin non-profit focusing on the needs and betterment of the homeless community. The community village this organization founded is a beautiful, solitary sanctuary, with mini-homes right out of a housekeeping magazine and gardens dotting the landscape. Weaving through the clusters of houses and RVs, the high school students knocked on doors and waited with baited breaths, holding copies of a survey they helped design for the residents of the village.

“I was pretty nervous,” senior Lydia Strickland said.

Over the course of the morning, the students went from door to door, talking to the residents and sharing their stories, working to fill the survey as their school project that would help Mobile Loaves and Fishes (also known as MLF) in its aim to fight homelessness. The math students worked in tandem with MLF to, ultimately, answer the question: Does a lack of community cause homelessness? The high school students used ideas and concepts learned throughout the year to edit, carry out, and analyze a survey given to the residents living in the community village the non-profit has made.

This question is largely based on Bruce K. Alexander’s “Rat Park” study, where Alexander and other scientists set up a study administering drugs to rats not in isolated cages, but in communities with a positive environment, and found that the drug intake of rats went down dramatically. This shows that environment and community play a significant role in drug use—and leads others to wonder if more than just drug use can be improved. The AP statistics and MLF worked together to explore this train of thought, and to reaffirm MLF’s community-based program.

Homelessness is, after all, a very real problem. According to the National Alliance to End Homelessness, there were 564,708 homeless people in the United States in January of 2015, 15% of which were considered chronically homeless. More pragmatically, each homeless person costs taxpayers around $14,480 a year. When you do the math, that amounts to homelessness costing more than eight billion annually.

Not only does homelessness affect those directly involved, but it impacts society as well. Efforts to curb homelessness will have a positive impact on everyone. As a large and established homeless outreach ministry based in Austin, Mobile Loaves and Fishes attempts to do just that—curb, and ideally eventually end, homelessness and the factors behind it. In partnering with the AP Statistics students of Regents School of Austin, MLF hoped to gain more data on the effectiveness of their Community First! Village and the philosophy that poor environment and lack of community are the root problems of homelessness.

“We believe what we’re seeing anecdotally on the property is being verified through the statistical analysis, so we love this [the AP Statistics project,]” Alan Graham, Mobile Loaves and Fishes co-founder and director, said. “It confirms our model at Community First, that the only model that’s going to move the needle in a significant way is a kingdom-based model that’s all about community. So we need that data.”

Not only has the AP Stats project helped as a service, but it’s also helped as learning tool for the students, giving them a deeper appreciation of the concepts they learned in class.

“I liked the real-world application,” junior Emily Raeder said. “That was great.”

Screen Shot 2017-05-11 at 9.06.53 AM.png

This service-learning model is meant to lead students into developing higher-order critical thinking, in a real-world environment, where service to the community (such as alleviating homelessness) is presented as crucial to the course objectives and larger applications of education. Dr. Wilkerson, the Regents AP Statistics and Calculus teacher, sees service-learning as a valuable tool in math education.

“I think it helps because you get to use statistics in a real-life situation that’s meaningful in an immediate context,” he said. “Students realize that what you learn in math class aren’t things you would just have to do down the road, in the distant foggy future. Students learn the connection between helping people and using statistics, and they learn it on a deeper level.”

The project showed that math and making a difference in the world can go hand in hand. In order to help Mobile Loaves and Fishes and its residents, the AP Statistics students at Regents had to learn exploratory data analysis, data collection, probability, and statistical inference. On top of all this, students also got to practice their speaking skills. Students presented the results to representatives from MLF, the culmination of the class’s hard work.

The high schoolers also got a better appreciation of how even the little things can affect the world around them.

“I talked to this one man who talked about what a difference people who give out bags with goodies at stoplights made, that it made his day,” one junior said. “He said those things made a big difference. But we don’t put much thought into it.”

These math students may just be proof that math really can accomplish anything.

Summer Institute 2017: Service-Learning in Mathematics

Screen Shot 2017-04-21 at 9.13.27 AM

Regents School of Austin, where I teach, will be hosting a summer institute for teachers and I’ll be leading a workshop on implementing service-learning in math courses. The target audience is math teachers at any level K-16 or pre-service math teachers.

Here are the details:

This workshop will assist you in developing successful service-learning projects in mathematics. Service-learning projects engage students in integrating their conceptual understanding of mathematics with the practical functioning of their local community. Ultimately students gain deeper content knowledge and a deeper appreciation for the role math plays in society.

Several examples of service-learning projects will be presented in detail from geometry and statistics, as well implementable ideas for other math courses. You will have the opportunity to brainstorm and work in conjunction with other educators to analyze the key components of a successful project, engage in discussion assessing the feasibility and logistics of implementing service projects in your own curriculum, critique project evaluation rubrics, and begin the design of your own service-learning project.

You will leave this workshop equipped to:

  • Determine the keys to a rewarding service-learning experience (after hearing personal testimony from students and community partners)

  • Modify and implement sample materials from past Regents projects (including project descriptions, calendars, and grading rubrics)

  • Connect the enduring understandings of your course with a community need

  • Evaluate student learning outcomes in keeping with your curriculum

  • Engage students with meaningful applications of math in the personal context of their local community

If you are interested, here is the link to registration page (that contains further details). 

Feel free to contact me if you have any questions and please share with colleagues that you think might be interested.
