A posting from Steven Downes OL weekly made me revisit one of my hobby horses:
teaching is not a profession, it is a service industry with some professionals working in it.
In support of this is the blind following of "myths of learning" that are still followed even though they have been proven to be poor scholarship. In Donald Taylor's presentation he resurrects:

"There's an old maxim in training:
You remember 10% of what you read
You remember 20% of what you hear
You remember 30% of what you see
You remember 90% of what you do
It's easily remembered. It's widely repeated.
It's easily remembered. It's widely repeated.
It's completely wrong." LINK
This was proven by Will Thalheimer (2006) to be very poor scholarship by a number of writers who misinterpreted and misrepresented earlier work. The full discussion is well worth reading.
"People do NOT remember 10% of what they read, 20% of what they see, 30% of what they hear, etc. That information, and similar pronouncements are fraudulent. Moreover, general statements on the effectiveness of learning methods are not credible---learning results depend on too many variables to enable such precision. Unfortunately, this bogus information has been floating around our field for decades, crafted by many different authors and presented in many different configurations, including bastardizations of Dale's Cone. The rest of this article offers more detail." LINK
This in itself is a strong indicator of the need for a greater emphasis on scholarship amongst teachers and the need to develop evidence based practice.
