One of the disadvantages of not reacting immediately is that something online might go offline. In this case it was a tweet of a slide from a self-proclaimed expert.

The slide was a rehash of the so-called learning pyramid. I hate how much it has been misrepresented that I refuse to show an example of it now.

But I only have to describe what has become common knowledge among new teachers and trainers — we supposedly only learn 5 or 10% from lectures, 10% from reading, 20% from audio-visual, and all that jazz. This is a bastardisation of Dale’s original Cone of Experience.

Dale's (1946) original Cone of Experience.

A few years ago, I shared how the learning pyramid with percentages has been debunked. But here is the short version.

  • Edgar Dale suggested in 1946 that media had effects on imparting information, and suggested a hierarchy of media effects.
  • This hierarchy was dubbed Dale’s Cone of Experience.
  • Dale did not suggest percentages to his theoretical model.
  • The hierarchy was about media effects, not retention or learning.

Despite this, Dale’s Cone was misused. Michael Molenda, someone I studied under, suggested that someone named Paul John Phillips, an instructor working at a military training methods branch, might have added retention rates without any backing from research. An early form of the learning pyramid was first published in 1967 by D. G. Treichler, again without any evidence.

It is easy to challenge the learning pyramid without mentioning the lack of research. Just ask the seller of snake oil how the percentages are in exact percentages of fives or tens. For example, how does a lecture ensure 5% of retention or learning? Why 5%? How was this measured? Why not deliver just that 5%?

Some things bear repeating. No, not the mythical percentages in the learning pyramid, but the fact that it was spread as a lie.

Most people would read the tweet above and agree. But first they must agree on the premise that the foolish thing is foolish in the first place.

If something is wrong, no amount of saying that it is right can make it right, right?

Not by today’s standards. While misinformation is not new, the speed at which it spreads and the frequency at which it can be delivered might allow falsehoods to anchor and normalise.

We also have fallacies in schooling and education, but these were not spread by quickness. Instead, they persisted by slow repetition, unquestioned practice, and uncritical thinking.

Fallacies like the rhetoric of engagement instead of empowerment, the confusion of choice with agency, gamification is game-based learning, schooling is education, enhancing lessons with technology instead of enabling learners and learning. Learning styles. Digital natives.

There is so much more and they have either normalised or are quickly cementing. As this happens, they only foolish ones seem to be those that question, critique, and berate. I am one of those latter fools.

For the second time in as many years, my son asked for a printout of our latest home utility bill. It was for a geography topic.

I have no objections to sharing how energy and water efficient we are, but I took care to block out personal information like our account number and address.

Perhaps teachers or designers of curricula think that an example from real life will connect with learners. It might. Then again, it might not. Kids do not normally worry about utility bills.

There is a more serious disconnect — the hardcopy. I asked my son why he could not share a digital copy on his phone. He replied that the instructions were to bring a printout.

A printout. This means that someone realised that we rely on e-bills now. The utility companies offer this as a cost-saving and timely measure, and customers are already on the bandwagon.

Why is a class disconnected from the new normal? Students will learn from teachers how not to question, to stick blindly with tradition, and to be prepared for the past.

Students will learn to play the game that is school. They will be schooled, but they may not be educated.
