Why evidence-based teaching methods are a bad idea
By Frank Furedi
At a time when society finds it hard to provide
compelling answers to the problems that people face, the realm of science is
being plundered in search of moral authority. The exhaustion of the old
taken-for-granted ideals, values and ideologies has led to a search for new
ways for validating views and opinions. Instead of trying to give meaning to
the problems we face through reflection and debate, governments now embrace
science as the unique source of truth.
This is giving rise to ‘policy-led science’ - that is,
science that has a tendency to mould itself around the needs of policymakers.
This strengthens the dogma of scientism, which aims to spread scientific
discourse into our personal, cultural and social experiences, where actually
other modes of non-scientific reflection are really needed. This is why, today,
we have everything from the ‘science of parenting’ to the ‘science of
happiness’ and the ‘science of the spiritual life’.
Scientism is now used to legitimate various policies
and claims made by all sorts of institutions. Consequently, evidence, or rather
evidence-based policy, which enjoys the authority of science, dominates the
modern political landscape. Today, policies are judged not on the grounds of
whether they are good or bad, but on the question of whether they are evidence-based.
Scientific evidence is, of course, a useful resource
for decision-makers. But not every research finding adds up to ‘evidence’ that
can directly be used to forge a new policy. Evidence needs to be tested,
interpreted and given meaning before it can become a reliable source of action.
The use of scientific evidence for political ends is particularly troublesome
in the sphere of social policy, where the problems facing people are
context-specific and mediated through various different influences and factors.
That is why, historically, so-called evidence-based policy has proven to be no
more or no less effective than policies driven by a more explicitly political
agenda.
Despite the undistinguished record of ‘evidence’-based
policy, governments desperate to legitimise their authority have embraced it
with unprecedented enthusiasm in recent years. An area where this is most
apparent is education. The growth of scientism in education is illustrated by
recent calls to introduce randomised control trials (RCTs) into schooling.
These calls, outlined by the science writer Ben Goldacre in a paper called
Building Evidence into Education, are supported by the UK’s Department of
Education.
A demand to have RCTs in relation to schools, in order
to work out which forms of education work best for children, is usually
justified through reference to the use of RCTs in the arena of health. In the
world of healthcare, RCTs have proven to be an invaluable resource for testing
the efficacy of different forms of medical interventions. Goldacre’s paper puts
forward an eloquent case for the role of RCTs in medical science. But exporting
a methodology from one discipline to another, in this case from health to
schooling, is always fraught with difficulties. Research methods that are
useful in medicine can be entirely inappropriate in the sphere of education.
Indeed, ideally methodologies for exploring the usefulness or otherwise of
certain approaches should emerge from within the specific disciplinary field
itself rather than being imported from other disciplines.
The pro-RCT lobby’s drawing of an analogy between
schooling and medical research is unhelpful, not least because it implies some
kind of equivalence between a child and a patient. Goldacre says: ‘Every child is
different, of course, and every patient is different, too; but we are all
similar enough that research can help find out which interventions will work
best overall, and which strategies should be tried first, second or third, to
help everyone achieve the best outcome.’
The problem with this drawing of a relationship of
equivalence between a child and a patient should be obvious to objectively
grounded researchers. The importing of a medical model into the discussion
about schooling is likely to distract educators from thinking freshly about the
challenges that they face. It is critical not to confuse teaching and education
with a so-called intervention,
in the medical sense. Why? Because to represent schooling as a form of
intervention is to undermine, and indeed violate, the integrity of the
educational enterprise
The medical definition of an intervention is ‘any
measure whose purpose is to improve health or alter the course of disease’. In
short, the narrative of intervention in the medical sphere takes as its
starting point the idea that there is a prior illness or deficit that needs to
be tackled. Such a concept is very unhelpful in education, since it treats
schools as the functional equivalents of hospitals. Yet where medical
interventions are about curing and healing and preventing, education is
principally about teaching - which is a very different thing.
Sadly, the use of the term ‘intervention’ in relation
to education is not arbitrary. Rather, it communicates a currently strongly
held dogma – the idea that children are afflicted by various emotional and
intellectual deficits that educationalists must ‘fix’ through an intervention.
The use of the term intervention reveals how much today’s cultural elite
believes in the existence of educational pathology – that is, great numbers of
children suffering from some form of quasi-medical educational deficit. This
pathological view was expressed in an extreme form by arecent report from the Centre
for Social Justice, which warned that there is an army of underclass children
starting school while still wearing nappies and behaving like toddlers.
From this medicalised outlook, children’s deficits are
seen to have logical priority over the other things that education is supposed
to be about. Just as doctors treat the sick and prevent illnesses from getting
worse, so teachers are being turned into educational healers who cure children
who are allegedly suffering from some pedagogically validated deficit.
As a result of this reimagining of what education is
for, imperceptibly the idea that children are ready to learn has given way to
the contrary assumption that they require some kind of intervention if they are
ever going to progress. Such an outlook has a big impact on how education is
carried out – it becomes more about damage limitation within the classroom
rather than having a commitment to teaching children what they need to know.
Indeed, the promotion of the ethos of intervention is
paralleled by the proliferation of therapeutic initiatives in the sphere of
education. Such therapy-based interventions are usually geared towards raising
pupils’ self-esteem or improving their ‘emotional literacy’ or ‘emotional
intelligence’. In their most caricatured form, these educational interventions
are delivered through wellbeing and happiness classes.
Of course, we should all be open to different and
often conflicting beliefs about how education and teaching should be carried
out. But whatever approach we choose to adopt, we need to understand that
education becomes warped, and alien to its very spirit, when it is reinvented
as a form of treatment. This tendency to medicalise education has many drivers,
most of which are independent of the schooling question. But one of its main
drivers is the one-sided emphasis of modern pedagogy on motivation, which
always leads inexorably to the question ofwhat works. This is also what
underpins the demand for evidence-based or RCT-fuelled education.
This point is stressed in a report published by
the Alliance for Useful Evidence. Titled Evidence
for the Frontline, the report says it wants to assist educators who want to
‘know what works’. Teachers’ preoccupation with ‘what works’ is understandable,
of course. But if the question of ‘what works’ becomes the central focus of
educational research and schooling practice, then we will see the privileging
of the means of education and the subordination of
the ends of education to the ethos of technical
instrumentalism. The key question asked by educators should be, ‘What do
children need to know?’. But unfortunately, the current obsession with what
works distracts us from thinking about the intellectual and knowledge content
of the curriculum. Moreover, the ‘what works’ culture leads inevitably to the
continual overhauling of the curriculum. So if the communication of a
particular field of knowledge does not work easily in schools, and proves
difficult for students, then it might be dispensed with by curriculum engineers
obsessed with ‘what works’. Such acts of philistinism are often justified on
the grounds that education should be relevant.
Evidence-based education, which is intimately linked
to the ‘what works’ culture, leads to a form of processed education. Processed
education is dominated by an instrumentalism that threatens to reduce education
to a technique and teaching to a technical intervention. As the French
sociologist Pierre Bourdieu explained, all ‘institutionalised learning
presupposes a degree of rationalisation’. However, when the ‘what works’
culture prevails, we end up with a pedagogy of hyper-rationalisation. Its main
accomplishment is to reorganise the curriculum around what works, which is
often very different to what children need to know. The proliferation of
anti-intellectual and anti-academic faddish subjects in modern schools is a
symptom of this trend.
Not only does the quest for an evidence base distract educators
from teaching and from confronting challenges - it also doesn’t work, even in
its own terms. The evidence generated through research has only a limited
applicability in the classroom situation. In education, randomised control
trials can only create or manufacture evidence that necessarily remains
external to the empirical reality of the classroom and its distinct contexts.
The classroom experience is constantly subject to fluctuation and change; what
occurs in a ‘trial’ is very distinctive and is very rarely reproduced in a real
school. An RCT carried out in a school only provides insights into how one
group fared against another. But the numerous variables – many of which are
actually external to the school – mean that such trials have at best a heuristic
value.
As many educators understand, what works for some
teachers may not work for others. For example, some research has conclusively
demonstrated that teaching reading through phonemic awareness is the most
effective form of instruction; other researchers insist that actually phonics
is the best way of teaching. The reality is that teaching reading through
phonemic awareness works for some, while phonics works for others. This seems
to be a secret to the Department of Education, which is splashing out money on
research into the work of effective teachers, in the hope that RCTs might help
to reproduce these teachers’ effectiveness in other classrooms.
My argument is not with educational research but with
the imperative of evidence-based education policy. At its best, educational
research can provide important insights into the relationship between various
social and cultural variables and pedagogic outcomes. These ideas are often
garnered through experience and reflection. Educational research can also
provide critically important ideas about teaching and learning. In this way,
the experience of the teaching profession can be distilled, communicated and
sometimes integrated into the work of the classroom.
But the principal problem educators face today is not
the dearth of educational research or a lack of evidence about ‘what works’,
but rather the increasing absence of any opportunity for them to exercise
professional judgment and to learn the value of what Aristotle call phronesis – the virtue of judgment.
Experimentation in education should be part of a teacher’s everyday life. What
we need is a pedagogy that is integral to the experience of the classroom, not
procedures inappropriately imported from the field of health.
