What is mathematics and why do we teach it?
The three required readings for this week, raises the questions of what mathematics is and why do, should, or would we teach it?
The first reading The Theory of Embodied Mathematics from the book Where Mathematics Comes From by Lakeoff and Nunez, discusses how some have a world view that is a part of their identity in believing what the authors have called Romance of Mathematics. Some points of the Romance are that mathematical truth is universal, absolute, and certain; that mathematics would be the same even if there were no human beings; and that mathematicians are the ultimate scientists. The authors state that beliefs like these intimidates people and leads many students to give up on mathematics as simply beyond them. The author’s goal is to make mathematics more accessible and give a more realistic picture of the nature of mathematics.
The second reading What Kind Of Thing Is A Number? Is an interview between John Brockman and Reuben Hersh. Hersh believes that mathematics is “ neither physical nor mental, it’s social. It’s part of culture, it’s part of history. It’s like law, like religion, like money, like all those other things which are real, but only as part of collective human consciousness” (Hersh, 1997). Hersh separates philosophers of mathematics into two groups which he calls Mainstream and Humanists and Mavericks. He states that Mainstream sees mathematics as inhuman or superhuman but Humanists see it as human activity. Hersh believes that “math is something human. There’s no math without people” (Hersh, 1997). He lists three possible philosophical attitudes towards mathematics. These are:
1) Formalism- math is calculations, has no meaning, follow rules to come up with the right answer, is connected with rote- your given an algorithm; practice it for a while; now here’s another one.
2) Platonism- math is about abstract entities which are independent of humanity, helps to make mathematics intimidating and remote.
3) Humanism- math is a part of human culture and human history, brings mathematics down to earth, makes it accessible psychologically, and increases the likelihood that someone can learn it.
Hersh believes that interaction, communication is essential and that students should interact not sit passively.
The third reading Why Teach Mathematics to All Students by Brent Davis addresses three questions. These questions each fall into a different question category. Question one is a teacherly question: Why do we teach mathematics to all students? Question two is a rhetorical question: Why would we teach mathematics to all students? Question three is a hermeneutic question: Why should we teach mathematics to all students? A teacherly question already has a determined answer; a rhetorical question expects no answer whereas a hermeneutic question allows for interpretation of an answer and can be expanded on. Davis believes that the first two cannot be questions at all because they either already have an answer or no answer can be given. The answer to all three questions however seem to come down to we teach mathematics because we have to.
After reading these three articles I believe my stance on mathematics is humanistic with a hint of formalism. I believe that math is social, cultural, historical but also physical and mental. This view comes out in the way I teach my students. I try to involve them in their own learning, always encouraging and prompting them to try different ways to approach and find a solution to a problem. I consistently use peer tutoring and small groupings allowing students to explore and discuss what they think with others. However, there is a touch of Formalism in that I believe that math does involve calculations and it is possible to come out with the right answer sometimes by following certain mathematical rules. This is one area that as teachers we have been changing our methods of teaching over the last few years. I learned long division in school by following rules. Now, I teach my students that the algorithm is just a method of showing your calculations not how to solve the problem.
Math needs to be connected to the real world for students. It has to have meaning to their lives. I had a student in my class one year who had absolutely no interest in any subject in school. He wanted to be outside, especially on the long liner with his family. Whenever I could, I used problems with him on calculating crab catches or payroll for the workers on his boat and he would have no difficulty digging in and finding a solution. This made sense to him whereas how much would it cost to buy 20 apples at the price of .35 cents each didn’t interest him. He didn’t like apples and had no intention of buying them. Math does have a humanistic philosophy for me. By making math interesting and relevant to the students’ real life wouldn’t we make it less intimidating and therefore more attainable for them?
