Last weekend, I spoke at the Debating Education event, at Michaela School, opposing mixed ability teaching. Hopefully the video of the event will appear in the next week or so. The following is a rough summary of what I said (i.e. it’s me going back over my notes and reconstructing my argument but nothing like my exact words). Obviously, it is in no way intended as a research article on mixed ability teaching or a summary of the evidence, just an explanation of my views. This is continued from Part 1.
Like a lot of trainee teachers, I was told on my PGCE course that the empirical evidence strongly supported mixed ability. It was a bit of a shock to look at this evidence and see how poor much of it is. A number of studies consist of tiny trials, where two schools (one with ability grouping, one without) are compared and the results of those schools reported back. Or in the case of Jo Boaler’s research, the actual results are ignored and mixed ability is reported to be better regardless. Even when you look at meta-analyses which include small trials like this, the outcome tends to show either virtually no impact, or a negative effect, for mixed ability. One of the few meta-analyses that suggests ability grouping is marginally harmful is Slavin (1990) though this was after including some remarkable outliers that others might well have ignored. Overall, Hattie combined the meta-analyses to find ability grouping to have an effect size of 0.12. Much of the so-called research in this area is little better than propaganda, declaring mixed ability to be right and attempting to shift the burden of evidence to its critics. Slavin, above, springs to mind as an example of this, his meta-analysis declared, a priori, that ability grouping was “anti-democratic” and “anti-egalitarian”. Betts et al (2000) also identified a tendency for research to compare progress for high and low ability sets with entire mixed ability sets (i.e. not just the high or low ability students in that set), and declare that this showed that while high ability students might do better in ability groups, low ability groups did worse. A trivial outcome that results from not comparing like with like. If there is any good research on setting, it is the randomised control trial conducted in Kenya by Duflo et al (2008) and it found a positive effect for ability grouping for students of all abilities.
It is sometimes claimed that ability grouping leads to stigma and labelling, i.e. that students in the bottom set will feel worse about themselves as a result. On the one hand I doubt this, because students are often even more acutely aware of their lack of ability when in the same class as their more able peers. But I would also look at what’s happened in the years since ability grouping became less popular. Far from refusing to identify the highest attainers as better, they have been listed as “gifted and talented”. Rather than ceasing to single out low attainers we now have 1 in five children identified as having SEN, often for nothing more than low academic attainment. This is not removing stigma; it’s ensuring that differences that could have been accommodated within the curriculum are now seen as problems that require more labelling and more treating students as fundamentally different.
Finally, it is often claimed that if education is focussed on equity, then that would give us reason to avoid ability grouping. It is claimed that it enables us to help the students who are most behind to make the most progress. But if we do want to help the least able, ability grouping favours that aim and mixed ability hinders . With ability grouping, schools can make conscious decisions to make the bottom sets smaller, or provide them with more resources, if they so choose. Mixed ability actually hinders support for the least able as they are split between different classes and dependent on different teachers. If we want to help the weakest, then ability grouping helps us meet their needs. You wouldn’t send everyone to hospital in order to avoid letting the ill and injured feel excluded. You wouldn’t send everyone to court or to prison, so that those who are actually accused or convicted of a crime can avoid stigma. If you set up a food bank, you would put it where the hungry could get to it, you wouldn’t just go from door to door in the nearest street giving everybody a sandwich. You don’t meet needs by ignoring them. Identifying what students need, and providing it, is the aim and ability grouping helps us achieve that.
Learning Styles Strike Back
November 30, 2015One of the few signs of progress in changing the debate in education had been a concerted rejection of the most obviously pseudo-scientific parts of the education climate, namely Brain Gym and learning styles. The greater involvement of cognitive psychologists in education, (e.g. Dweck and Willingham), challenges from outside education (e.g. Goldacre) , the creation of ResearchED and the opening up of debate on social media had helped create a climate where these most obvious frauds could not hope to flourish. Even those conducting and promoting rotten research would use opposition to learning styles and Brain Gym to signal that they were not complete charlatans.
Sometimes the picture of progress was mixed, particularly for learning styles. Evidence suggested teachers still believed in them. University PGCEs continued to recommend books that encouraged their use, but a growing number would also include a lecture denouncing them. Some would even show Dan Willingham’s video on the subject:
Textbooks used in teacher training still mentioned learning styles, but they might at least signal that there was some debate around them. There were frequent stories of schools and colleges still using VAK tests or putting VAK boxes on lesson planning forms but they were no longer ubiquitous. I did highlight some cases of the continued promotion of learning styles here. I can add to this. When the College of Teaching announced its trustees, one was described in the TES as having “enjoyed carrying out research into learning styles”. A recent OFSTED report for Bedford Academy contained the following comment:
So the myth was not dead, but it was at least something that turned up unexpectedly, rather than being all over the place. At the very least, where people were familiar with the debate, there seemed little dispute about which side was supported by evidence and which side was, either accidentally or deliberately, spreading lies.
However, over the weekend, a concerted backlash to the rejection of learning styles appeared on Twitter and in blogs. Most of it followed the standard ploys used against scientific evidence (and involved the usual fallacies):
I’m not going to explain why each of these fallacies is a fallacy; that can be found online or in any good book about pseudo-science or valid and invalid arguments. But I will make a simple point about why this matters. Learning styles are not simply a misconception, like discovery learning, that spread before people had a chance to check the evidence. They are not a hypothesis, like Bloom’s Taxonomy, that was proposed with the absence of evidence admitted. The dominant ideas about learning styles stem from a well-known body of fraudulent theory (Neuro-Linguistic Programming) and from rewriting the ideas of Howard Gardner without his agreement. Learning styles tools have been invented and sold by people who had no reason to claim they work. Therefore, it is fair to say that the claims about learning styles are not simply wrong, they are lies. I don’t hesitate to claim that most of what teachers have been told about learning styles is simply a pack of lies. In education it is a given that we might disagree; that we might think other people are wrong. But this is different. This is about whether it is okay for people to spread lies in education, whether deliberately or through having been fooled themselves. It is worth asking what future we have as a profession if teachers or educationalists are complacent – or indifferent – about lying.
Update: I posted this just now, without adding the following important point. If any of the people who denied that learning styles were bogus, were actually right then they need to explain why they haven’t attempted to claim the prize offered to anyone who can demonstrate a useable system of learning styles. It currently stands at $5000. Details here.
