Educating Over and Over Again Evidence Based
For teachers to exist like doctors, and base practice on more "scientific" research, might seem similar a good idea. But medical doctors are already questioning the narrow reliance in medicine on randomised controlled trials that Australia seems intent on implementing in didactics.
In randomised controlled trials of new drugs, researchers get 2 groups of comparable people with a specific problem and give one grouping the new drug and the other group the old drug or a placebo. No one knows who gets what. Not the doctor, not the patient and non the person assessing the outcomes. Then statistical analysis of the results informs guidelines for clinical practice.
In education, though, students are very unlike from each other. Unlike those administering placebos and existent drugs in a medical trial, teachers know if they are delivering an intervention. Students know they are getting one matter or some other. The person assessing the state of affairs knows an intervention has taken place. Constructing a reliable educational randomised controlled trial is highly problematic and open up to bias.
As a doctor and instructor thinking, writing and researching together nosotros believe that a more honest agreement of the ambivalences and failures of show-based medicine is essential for education.
Before Australia decides teachers need to be like doctors, nosotros want to tell you what is happening and give you some reasons why testify based medicine itself is said to be in crunch.
1. Randomised controlled trials are just 1 kind of prove
Medicine now recognises a much broader evidence base than only randomised controlled trials. Other kinds of medical evidence include: practical "on-the-job" expertise; professional noesis; insights provided by other research such as case studies; intuition; wisdom gained from listening to patient histories and discussions with patients that let for shared decision-making or negotiation.
Privileging randomised controlled trials allows them to become sticks that beat practitioners into uniformity of practice, no affair what their patients want or demand. Such practitioners go "cookbook" doctors or, in didactics, potentially, "cookbook" teachers. The all-time and most recent forms of evidence based medicine value a broad range of prove and do non create hierarchies of evidence. Education policy needs to consider this advisedly and treat all forms of evidence equally.
2. Medicine tin be used every bit a great
Teaching is a feminised profession, with a much lower status than medicine. It is easy for science to exert a masculinist authority over teachers, who are required to exist ever more scientific to seem professional person. They are chosen on to be phallic teachers, using data, tools, tests, rubrics, standards, benchmarks, probes and scientific trials, rather than "soft" skills of listening, empathising, reflecting and sharing.
A Western scientific evidence-base for practice similarly does not value Ethnic knowledges or philosophies of learning. Externally mandated guidelines also negate the concepts of pupil voice and negotiated curriculum. While confident doctors know the randomised controlled trial-based statistics and issue sizes need to exist read with scepticism, this is not so like shooting fish in a barrel for many teachers. If randomised controlled trial-based guidelines are to rule teaching, teachers volition also potentially be monitored for compliance with guidelines they may non fully understand or accept, and which may potentially harm their students.
3. Evidence based medicine is about populations, not people
While medical randomised controlled trials save lives past demonstrating the broad effects of interventions, they brand individuals and their needs harder to perceive and respect. Randomised controlled trial-based guidelines tin mean that diverse people are forced to conform to simplistic ideals. Rather than starting with the patient, the doctor starts with the rule. Is this what we want for teaching? When medical guidelines are practical in rigid means, patients tin be harmed.
Trials cannot be done on every unmarried kind of person and and then inevitably, many individuals are forced to have treatments that will not benefit them at all, or that are at odds with their wishes and beliefs. Educators demand to ensure that teachers, not bureaucrats or researchers, remain the authority in their classrooms.
5. Scientific prove gives ascension to gurus
Bear witness-based practice tin can give rise to the cult of the guru. Researchers such as John Hattie, and their trademarked programs like "Visible Learning" based on apparently infallible science, tin can rapidly colonise and dominate education. Withal their medicalised glamour disguises the reality that there is no universal and enduring formula for "what works".
In 2009, in his book Visible learning: A synthesis of over 800 meta-analyses relating to accomplishment Hattie advised that, based on prove, all healthy people should take aspirin to prevent heart attacks. Withal also in 2009, new medical evidence "proved" that the harms in salubrious people taking aspirin outweigh the benefits.
In 2009 Hattie said class size does not matter. In 2014, further research found that reducing class size has an important and lasting touch, especially for students from disadvantaged backgrounds.
While medical-style guidelines may seem to have come from God, such guidelines, even in medicine are frequently multiple and contradictory. The "cookbook" teacher will always exist chasing the latest guideline, disempowered by meridian-down interference in the classroom.
In medicine, over five years, fifty percentage of guideline recommendations are overturned by new bear witness. A comparable situation in educational activity would create unimaginable turmoil for teachers.
6. Show-based practice risks conflicts of interest
Educational publishers and platforms are very interested in "scientific" show. If a researcher can "prove" an intervention works and should be applied to all, this means big dollars. Randomised controlled trials in medicine routinely produce outcomes that are to the benefit of industry. Just certain trials become funded. Much unfavourable research is never published. Drug and medical companies set agendas rather than responding to patient needs, in what has been described equally a guideline "mill".
Imagine how this will play out in pedagogy. Do we want what happens in classrooms to be dictated by profit driven companies, or student-centred teachers?
What needs to happen?
Nosotros call for an urgent halt to the imposition of 'evidence-based' education on Australian teachers, until in that location a fuller understanding of the benefits and costs of narrow, statistical evidence-based practice. In item, education needs protection from the likely exploitation of evidence-based guidelines by industries with vested interests.
Rather than removing teacher agency and enforcing subordination to gurus and data-based cults, pedagogy needs to embrace a wide range of evidence and reinstate the teacher as the practiced who decides whether or not a guideline applies to each student.
Pretending teachers are doctors, without acknowledging the risks and costs of this, leaves students consigned to boring, standardised and ineffective cookbook teaching. Do we want teachers to kickoff with a recipe, or the person in front end of them?
