“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.
