Framing Mathematics

We had a numeracy PD day a few weeks ago.  This filled me with trepidation having barely survived high school mathematics.  It began with a warning about how we frame the subject:



Fair enough.  Evidently I'm not the only one who treats mathematics with caution, but I can see the point about how negatively framing maths with students can cause problems.  If you don't think maths are a useful tool that can help you solve real world problems then you've been living under a rock.  Everyone should develop basic numeracy.  I'll try and do better with how I'm framing it, but that doesn't mean maths gets a free pass on how it's delivered.

We then did a maths based online escape room exercise with Edtechteam.  This was an engaging process, but it cast a bright light on what was for me one of the problems with trying to learn maths: parsing poorly written word problems.

When one of our group (a published playwright with a Masters in English) suggested that the questions were vague to the point of being misleading the math teacher in our group said, "yeah, but any language based question is going to be somewhat unclear."  The English teacher looked at her quizzically and said, "no it isn't."

Therein lies the problem.  If a teacher who has never focused on developing strong language skills gets lost in creating nuanced word problems to get at complex mathematics, you can see where this might go wrong for everyone.


From the point of view of someone who doesn't pick up maths easily, confusing language doesn't engage me, it does the opposite.  I'd rather (and I speak as an English major) have the maths served straight up without any confusing or misleading language in the mix, but maths teachers seem determined to lean on language skills they don't have in order to confuse the numeracy they do have.

This problem appeared again when we got out to an exercise where we (again, in groups) were supposed to find factors in an array of numbers, but rather than simply explaining the logic involved, the activity was dressed up in a tax avoidance theme that made no sense to me or the science and history teachers I was working on it with.  So far this morning both maths activities had demanded that we embrace confusing and contradictory language in order to get at the logic below.

In this activity, if you selected a number to get paid the 'tax man' got all the factors of that choice.  So if you picked twelve, the tax man got 1  2, 3, 4 and 6 dollars.  When I asked how I was being taxed $16 on the $12 I made I was told that the taxes don't actually come out of the money I was making, which isn't helpful.  When I suggested that people should pay taxes in order to support all the  benefits of society they enjoy and shouldn't be trying to dodge paying them, I was told that I was putting too much thought into this.  At least someone is.  This has always been the way with me and mathematics, especially when it dresses itself up in confusing language in a desperate attempt to appear more interesting.

I think I'm a pretty sharp fellow.  I've been able to calculate binary subnets in order to build networks and I've never had trouble doing the maths needed to be a mechanic or a technician.  When the maths are immediate and real I'm able to get a handle on it, but the bubble gum world of high school mathematics has always alienated and confused me.  It seems arbitrary and nonsensical because it often is.

Maybe the best way we can frame mathematics is to stop trying to make it into something it isn't.  If we treated it like the tool it can be instead of trying to turn it into some kind of spy based action adventure or libertarian tax dodging daydream, we wouldn't have so many people feeling alienated by it.


Of course, the solution is obvious but how we solve it is prevented by how we organize education into departments.  If we collaborated on word problems with the English department, we'd remove a lot of that confusion.  If we applied our mathematics through science, business and technology we wouldn't get lost in the confusion of maths for maths' sake.  We could be applying mathematics in the statistics we use in social sciences or  the ratios we use in art, but we separate numeracy off in high school and let it atrophy in a maths classroom that struggles to connect to the real. 


Ironically, our PD followed these two engaging but ultimately confusing activities up with two teachers telling us about their experimental manufacturing technology-mathematics combined course which encourages applied maths students to work through manufacturing technology in solving real-world problems.  No imaginary tax schemes.  No escape rooms.  Just applying maths to real world problems in an unobstructed and meaningful way that leads to outcomes that are transparent and obvious.

This would mean combining mathematics with other courses and then working to integrate numeracy into those subjects in a constructive and transparent way.  There could still be an academic/abstracted mathematics stream for the tiny percentage of students who would need it, but for those of us who aren't aiming to be theoretical physicists or academic mathematicians, we need our math served up without the garnishes.  Knowing what we're doing it and why we're doing it would go a long way to alleviating the maths anxiety so many of us have.

Forcing An Apple To Become An Orange

We emigrated to Canada in 1977.  Unfortunately, my parents weren't really paying attention and moved us (an English speaking family from England) into Lasalle in Montreal, Quebec.  If you don't know what was going on in Quebec in 1977, it wasn't good for an eight year old English kid.  While we were struggling to adapt to a new country we'd also wandered into a nationalist revolution.  Bill 101 made it illegal for immigrants to learn in English.  Since that was my native language and I had no background in French, the provincial government told my parents I'd have to attend a french school and get dropped back two grades to accommodate my lack of language skills.

While that was going on, the kids in our predominantly French neighborhood had overheard me talking with my lovely Norfolk accent while walking home from school and had decided that I would be a great opportunity to express their Quebecois pride. Getting beaten up by half a dozen kids at once wasn't any fun, but when they started bringing their german shepherd along to help, it was even less fun.  You'll have to excuse me if I'm not enthusiastic about Quebec's very singular approach to immigration.

Government letters arrived telling my parents that they had to move me out of English school or they would be charged and jailed.  My dad's new job did backflips, opened up a branch office in Toronto and we escaped to free Canada in 1980.  I've had a soft spot for Ontario's open arms approach to immigrants ever since.


@dougpete shared an article on Quebec's math prowess this morning.  I have some strongly held beliefs about how they've managed this result that the article itself goes to great lengths to ignore.  While Ontario has what is described by many people as too many public school systems, Quebec has one, and it's one that caters aggressively and exclusively to a single language supporting a single culture.  They don't enjoy immigration and their provincial politics have backed that up since I was an eight year old way back in 1977.  If you're looking  for a province that struggles to embrace multiculturalism, Quebec's a fine example:

"Among the provinces, the greatest increase in the absolute number of police-reported hate crimes was observed in Quebec, where incidents rose from 270 in 2015 to 327 in 2016. This increase was mostly attributable to more hate crimes targeting Arabs and West Asians, the Jewish population and sexual orientation."  
- Stats Canada Daily: Police reported hate crime, 2016


With the exception of New Zealand (which is significantly less
multi-cultural than Canada
anyway), there are few other countries
in the top 20 that sport a significant immigrant population.
I would argue that if you're dealing with a less diverse population you're dealing with an easier education process.  In addition to removing hard barriers like language and the various qualities of education in home countries, you're also bypassing many of the less tangible complexities like cultural expectations around gender and religion.  These benefits are clearly seen in international education rankings where monocultural societies are much more willing and able to force compliance and efficiently produce results for standardized tests; standardized populations feed strong standardized results.  With no language barriers or cultural confusion, it pays to be monocultural in standardized testing.  Canada is exceptional in those results, especially considering how it's a country built on immigration.  That we are able to produce these results even while working with diverse often ELL populations is astonishing.  Statistics show just how challenging trying to cover curriculum while also teaching the language of instruction is.  Stretching your education system to provide support for such a diverse population means you aren't going to score as well on a standardized test because your students aren't standard.

Quebec students pay a third what Ontario university students do.
They can afford to stay in four year programs for teacher training
while Ontario teachers would end up paying tens of thousands of dollars
more for that privilege.  You can encourage extended teacher
training when you know it isn't going to bankrupt your citizens.
In addition to the diversity of their students, there are a number of assumptions made in that article that ignore the cultural landscape that has allowed Quebec to produce this outstanding mathematical outcome that is out of step with the rest of the country.  Under more extensive teacher training is this:

Teacher preparation programs in Quebec universities are four years long, providing students with double the amount of time to master mathematics as part of their teaching repertoire, a particular advantage for elementary teachers. In Quebec faculties of education, elementary school math teachers must take as many as 225 hours of university courses in math education; in some provinces, the instructional time can be as little as 39 hours.

That Quebec students receive much more support for post secondary than Ontario students is a matter of fact.  Quebec looks after its teachers in training by not financially crippling them with this long term training.  Expecting Ontario teachers in training to foot an Ontario sized bill for their Quebec length training only goes to highlight the fundamental differences between the provinces.  Quebec students pay more than a third less what Ontario students do for that university training, and so they are able to extend their training.  It's little wonder that they are producing better results on this standardized test.

The article kicks off rather hyperbolically sounding an alarm for Ontario's math's results:  
"That populist election cry resonated with Ontarians because Ontario students continue to lag in mathematics and were the only ones in the country to show no significant improvement on national tests from 2010 to 2016."
Saskatchewan also has a dip in results and most of the other provinces were all within a couple of percentage points of their previous scores.  More importantly, Ontario led the results for English speaking Canada in 2010, 2013 and 2016, and even managed to slightly improve on it.  So this emergency in Ontario is based on the fact that we've always been leading in mathematics scores in multicultural Canada?  I hope everyone else catches up with us one day, but with the provincial government about to pull one of the top performing English Canada education systems to bits, I wouldn't bet on it.

In researching this I came across some evidence that the Quebec of today isn't as totalitarian as the Quebec I emigrated to in 1977.  This research on current Quebec schools summarized it this way:

"Quebec’s traditionally homogeneous French-language education system has undergone some radical changes over the past 30 years and continues to be shaped by public policies geared toward promoting French and openness to ethno-cultural diversity. The province has come a long way and now compares favourably with other immigrant-receiving societies. Nevertheless, many challenges lie ahead. Among other things, the marginalization of some ethnic groups, and most especially that of the Black community, must be better understood and actively prevented."

Perhaps Quebec is a bit less mono-cultural than I remember, but it still enjoys all the benefits of encouraging only primary language speakers into their system.  With that language of instruction time and energy freed up and with government subsidized education that allows their teachers to enjoy extended training without financially crippling them, Quebec is enjoying the results it deserves.  I'd rather Ontario didn't try to copy them though.  As an immigrant myself, Ontario made me feel welcome in a way that Quebec didn't, and I hope we'll continue to do that for the people across the world, regardless of the language they speak, who come here to find a home.

The article ends up questioning its own bias on Quebecois superiority in math as it wraps up:

Quebec is markedly different when it comes to mathematics. Immersed in a French educational milieu, the Quebec mathematics curriculum has been, and continues to be, more driven by mastery of subject knowledge, didactic pedagogy and a more focused, less fragmented approach to student intellectual development. Socio-historical and cultural factors weigh heavily in explaining why Quebec continues to set the pace in mathematics achievement. A challenging curriculum produces higher math scores, but it also means living with lower graduation rates.

Perhaps the Ontario panic over mathematics could do with a bit of context, but I fear that won't happen in the populist, reactionist times we live in.  It's better to invent an emergency, compare ourselves to a system that couldn't be more different and then try to imitate their results than it is to continue to lead English speaking Canada in mathematics?  I sincerely hope not.
