Moshe Renert (2011) argues that mathematics education must address the difficult global challenges of our time. In particular, teachers have a duty to educate students on the mathematics and science of climate change so that they are prepared to have informed discussions and contribute to the solution. One quote that made me reflect on my own growth as a teacher is this (Renert, 2011):
Mathematics is popularly conceived of as a pure body of knowledge, independent of its environment, and value-free (e.g. Hardy, 1940). From the Platonist perspective, connections between global warming and the topics found in mathematics textbooks, such as fractions or quadratic equations, are not readily apparent. (p. 20)
I would have likely agreed with the "popular conception" at the start of the B. Ed. program and not really cared that fractions and quadratic equations aren't easily relatable to global warming or any "real life" issues. Personally, I still think of mathematics as a mostly "pure body of knowledge" that is fun to study for its own sake. I used to believed that sharing my passion and knowledge is my primary responsibility as a teacher, but as I've been reading on the extent that teachers influence their students, discussing the purpose of schooling and the role of teachers, and studying how and why the curriculum is written the way it is, I've come to value the social aspects of teaching – teachers must prepare students to participate in their society. I believe that Renert is justified in his call to include subjects like climate change in math lessons.
I used to think that the common complaint that school doesn't teach things that are relevant to real life was not really fair and can be addressed by showing passion and demonstrating how learning abstract things can be fun and rewarding. I still think that learning abstract ideas is important and that it can be fun, but I am warming to the idea that the complaint is legitimate and that teachers do have a duty to try to show their students why they are learning the subjects we teach them.
I also really like Renert's (2011) example of a transformative approach to teaching how to think about large numbers:
Most mathematical problem solving in today's classrooms relies on the unchallenged assumptions that each problem has one correct answer and that the teacher knows this answer. Students' creativity is therefore limited to replicating solutions that are already known by an adult. In contrast, the solutions to many problems of sustainability are not known a priori , and in some cases there is no certainty that solutions can be found at all. A different order of ingenuity is required to approach these problems,one that we may call radical creativity. (p. 23)
I think this is still a very common issue at school, even at the undergraduate level and I look forward to designing lessons with this transformative approach in my practicum.
