The real challenge is managing classrooms with wide-ranging student needs, from special education to language barriers

By Michael Zwaagstra

Teachers’ unions have long pushed for smaller class sizes, but the real challenge in schools isn’t how many students are in the room—it’s how complex those classrooms have become. A class with a high proportion of special needs students, a wide range of academic levels or several students learning English as a second language can be far more difficult to teach than a larger class where students are functioning at a similar level.

Earlier this year, for example, the Elementary Teachers’ Federation of Ontario announced that smaller class sizes would be its top bargaining priority in this fall’s negotiations.

It’s not hard to see why unions want smaller classes. Teaching fewer students is generally easier than teaching more students, which reduces the workload of teachers. In addition, smaller classes require hiring more teachers, and this amounts to a significant financial gain for teachers’ unions. Each teacher pays union dues as part of membership.

However, there are good reasons to question the emphasis on class size. To begin with, reducing class size is prohibitively expensive. Teacher salaries make up the largest percentage of education spending, and hiring more teachers will significantly increase the amount of money spent on salaries.

Now, this money could be well spent if it led to a dramatic increase in student learning. But it likely wouldn’t. That’s because while research shows that smaller class sizes have a moderately beneficial impact on the academic performance of early years students, there is little evidence of a similar benefit for older students. Plus, to get a significant academic benefit, class sizes need to be reduced to 17 students or fewer, and this is simply not financially feasible.

In addition, not only does reducing class sizes mean spending more money on teacher compensation (including salaries, pensions and benefits), but it also leads to a decline in average teacher experience and qualifications, particularly during teacher shortages.

As a case in point, when the state of California implemented a K-3 class-size reduction program in 1996, inexperienced or uncertified teachers were hired to fill many of the new teaching positions. In the end, California spent a large amount of money for little measurable improvement in academic performance. Ontario, or any other province, would risk repeating California’s costly experience.

Besides, anyone with a reasonable amount of teaching experience knows that classroom complexity is a much more important issue than class size. Smaller classes with a high percentage of special needs students are considerably more difficult to teach than larger classes where students all function at a similar academic level.

The good news is that some teachers’ unions have shifted their focus from class size to classroom complexity. For example, during the recent labour dispute between the Saskatchewan Teachers’ Federation (STF) and the Saskatchewan government, the STF demanded that a classroom complexity article be included in the provincial collective agreement. After the dispute went to binding arbitration, the arbitrator agreed with the STF’s request.

Consequently, Saskatchewan’s new collective agreement states, among other things, that schools with 150 or more students will receive an additional full-time teacher who can be used to provide extra support to students with complex needs. This means that an extra 500 teachers will be hired across Saskatchewan.

While this is obviously a significant expenditure, it is considerably more affordable than arbitrarily reducing class sizes across the province. By making classroom complexity its primary focus, the STF has taken an important first step because the issue of classroom complexity isn’t going away.

Obviously, Saskatchewan’s new collective agreement is far from a panacea, because there is no guarantee that principals will make the most efficient use of these additional teachers.

Nevertheless, there are potential benefits that could come from this new collective agreement. By getting classroom complexity into the collective agreement, the STF has ensured that this issue will be on the table for the next round of bargaining. This could lead to policy changes that go beyond hiring a few additional teachers.

Specifically, it might be time to re-examine the wholesale adoption of placing most students, including those with special needs, in regular classrooms, since this policy is largely driving the increase in diverse student needs. While every child has the right to an education, there’s no need for this education to look the same for everyone. Although most students benefit from being part of regular academic classes, some students would learn better in a different setting that takes their individual needs into consideration.

Teachers across Canada should be grateful that the STF has taken a step in the right direction by moving beyond the simplistic demand for smaller class sizes by focusing instead on the more important issue of diverse student needs.
