“Opinions don’t affect facts.
But facts should affect opinions, and do, if you are rational.” (Ricky Gervais)
I thought I would not have to blog about these fads again but it seems they have the strange ability to be reborn every single year and surface in professional development courses as well as in tweets, blog posts, and conversations within the education community. The reasons are different, ranging from ignorance to vested interests, but the effect is the same: poorer teaching. And no, you are not a bad teacher because you used them but you are a less effective one. We need to learn to dissociate our practice (which can have flaws) from our beliefs formed in the background of consistent bad professional development provided by schools.
Let’s see these monsters in their entire splendor:
- The Cone of Learning / The Learning Pyramid
- Learning Styles
- Right-Left Brain
- Brain Gym
- Brain-Based Learning
- Multiple Intelligences
The Learning Pyramid – a complete bogus
Where does it originate? Edgar Dale’s Cone of Experience (1946) was an exclusively theoretical model for audio-visual media, it did NOT include any percentages, and Dale himself insisted that the classifications should NOT be regarded as “any sort of hierarchy or rank order”.
Where did the percentages come from? Don’t laugh. They were first published by an employee of Mobil Oil Company in 1967, writing in the magazine Film and Audio-Visual Communications. This employee, D.G. Threichler, provided NO evidence for the figures but the education community accepted the percentages nonetheless.

I could go on and on with evidence – just type “cone of learning debunked” and you’ll see hundreds of papers on the topic.
Learning Styles – no, really, they do not exist
I am sure you came across this numerous times and some of you, more unfortunate, had to design lesson plans accordingly and meet the “various learning styles of students”. Well, they were debunked over and over again by experts, from psychologists to educationalists and research.
The studies that purport to provide evidence for learning styles “fail to satisfy key criteria for scientific validity.” (Hal Pasher et al, Psychological Science in the Public Interest, 2009)
“VAK (n.n. visual, auditory, kinesthetic styles) might, if it has any effect at all, be actually harming the academic prospects of children.” (Professor John Geake, Neuormythologies in Education, 2008)
Many blogs were written and research evidence piled up for more than a decade yet this myth continues to be embraced by schools and, consequently, teachers.

Left-Right Brain – no such thing
“The myth probably took root in the 1800s, when scientists discovered that an injury to one side of the brain often caused a loss of specific abilities. The myth gained ground in the 1960s, when scientists studied epilepsy patients who had surgery to sever the connection between the two hemispheres.
But more recently, brain scan technology has revealed that (…) the two hemispheres are in fact highly complementary.” Brain Myths, BrainHQ
” The application of this notion to educational practice seems, therefore, overly simplistic and even dubious.
The notion of different hemispheric thinking styles is based on an erroneous premise: each brain hemisphere is specialized and therefore each must function independently with a different thinking style. Furthermore, there is no direct scientific evidence supporting the idea that different thinking styles lie within each hemisphere. Indeed, deriving different hemispheric thinking styles from functional asymmetries is quite a bold venture, which oversimplifies and misinterprets scientific findings.” Neuromyth 6, Center for Research and Innovation, OECD

Brain Gym® – more snake oil in education
This was one of the most entertaining nonsensical claims sold to and, unfortunately bought by educators. Did I tell you it is used in 80 countries?
The website is riddled with hilarious statements backed by zero evidence. We learn about “crawling, drawing, tracing symbols in the air, yawning, and drinking water” as efficient methods to enhance learning…except they do not.
“Brain Gym was created in the 1980’s by Dr. Paul Dennison and Gail E. Dennison, who ‘were seeking more effective ways to help children and adults who had been identified as ‘learning disabled.’ They drew from a large body of research by developmental specialists who had been experimenting with using physical movement to enhance learning ability.” They called their work Educational Kinesiology or Edu-K for short. Paul worked with chiropractor Richard Tyler,* a friend of Arnold Schwarzenegger’s and a proponent of “alternative chiropractic.”
Go figure. But there is more.
“Unfortunately, the research they drew on has been widely discredited (Bruer 2004; Hyatt 2007; Novella 1996) and the follow-up research on the program itself is laughably inadequate. There have been only a few published studies on Brain Gym. One involved four participants, one of whom was the author of the study. Three were published in a journal that requires the authors to pay for publication. Another study has serious methodological flaws.”

Brain-Based Learning – because learning does not happen in the brain, sic!
I know. You can hardly suppress a smile. Replace “brain” with any number of words you wish. For instance, “nose-based learning”. Or “chocolate-based learning”.
Besides the hilarious linguistic use (it is the brain that coordinates all learning, regardless of the type of stimuli, i.e. visual, and the skills that are being built, i.e. motor), “brain-based learning strategies” seem to be the most dangerous *because* they seem supported by neuroscience and those promoting them intentionally misuse scientific findings. We all know that if there is “evidence” or some statistics thrown in, people are more prone to accepting claims.
“This is a common tactic. Many of these companies have an impressive-looking page of research on their websites. On closer inspection, these turn out to consist of articles only vaguely related to their claims.
Such marketing tactics are not new, and it is hard to get too morally exercised over a group of business people finding a new way of scamming another group. But consider the growth of businesses that target parents, teachers, and schools, using similar language.
Educational neuroscience is a thriving field of research, and there are many excellent and doubtless well-meaning researchers doing rigorous and valuable work in the area. Unfortunately, there are also businesses that want to exploit teachers’ lack of experience and middle-class parental anxieties about school attainment.” (Matt Wal, Researcher in Brain Imaging, Imperial College London)
In many ways, repackaging flawed research and selling it to schools so that they “improve” learning reminds me, sadly, about Dr. Fox lecture where the experimenters proved that even nonsense talk can be easily accepted by listeners since they are not experts in the field.
I recommend that you read Dr. Will Thalheimer’s latest post (Brain-Based Learning and What Neuroscience Says) as he has evidence, interviews, as well as a clear argument as to why these “strategies” can harm education in the long run.
Multiple Intelligences – deceivingly optimistic
All of us know about Gardner’s MI theory. Unfortunately, it has never been supported by research for various reasons.
First, the use of terms was ambiguous and not even later was there an agreement as to what each of them stands for.
Secondly, little empirical research was conducted during this time: something that cannot be isolated and assessed (i.e. “naturalistic intelligence”) cannot claim scientific validity.
Thirdly, the greatest majority of scientists do not really accept the theory.
“Lynn Waterhouse in 2006 found no published studies at all that supported the validity of the theory. Even though Gardner first made his theory public in 1983, the first empirical study to test the theory was not published until 23 years later (Visser, et al., 2006a) and the results were not supportive. Multiple intelligences theory can hardly be described as scientifically generative.
Gardner’s theory of multiple intelligences looks to be a confused and nebulous set of claims that have not been empirically validated. Many of Gardner’s proposed “intelligences” appear to be explainable in terms of existing concepts of personality and general intelligence, so the theory does not really offer anything new. Additionally, some of the proposed “intelligences” are poorly defined (particularly intrapersonal) and others (e.g. musical) may be more usefully thought of as skills or talents. The popularity of Gardner’s theories in educational contexts may reflect its sentimental and intuitive appeal but is not founded on any scientific evidence for the validity of the concept.” (The Illusory Theory of Multiple Intelligences, in Psychology Today, Scott A. McGreal MSc)
Professor John Geake on Multiple Intelligences: “Neuroimaging studies do not support multiple intelligences; in fact, the opposite is true.” (Neuromyths and Why They Persist in the Classroom, Sense About Science)

In conclusion, do not just roll your eyes when one or more of these fads are discussed in your PD meetings. Show the evidence and help discourage bad practice. We owe it to our students to teach better than this. And to our stakeholders to stop wasting money on programs that hardly make any real difference in learning, or worse, may cripple it.
And I leave you with a chart I created two years ago – how to deal with any claims, ed. program, or research (I am @surreallyno on Twitter).
A report on neuromyths and teacher training was released in January (see below) – please read this article prior to the paper – We Need to Rewrite the Textbook on How to Teach
