Many sources attribute William Glasser with research that shows that
students retain: 10 percent of what is read; 20 percent of what is
heard; 30 percent of what is seen; 50 percent of what is heard and
seen; 70 percent of what is said; and 90 percent of what is said and
done.
I'm looking for the full citation for the published article or book in
which Glasser, or an earlier author(s), published a study supporting
the above result - as well as the passage(s) from the article or book
that states this result. |

I've found numerous references attributing this to Glasser, but none
of them specify an exact source or date. There is a very similar quote
by Sandra Rief which does have a known source:
"Students retain:
10% of what they read
20% of what they hear
30% of what they see
50% of what they see and hear
70% of what they say
90% of what they say and do
Source: Rief, Sandra F., How to Reach and Teach ADD/ADHD Children:
Practical Techniques, Strategies, and Interventions for Helping
Children with Attention Problems and Hyperactivity. The Center for
Applied Research in Education, 1993. p.53."

"According to the noted educator Sandra Rief(1), students retain
10% of what they read
20% of what they hear
30% of what they see
50% of what they see and hear
70% of what they say
90% of what they say and do.

Is the Rief quote satisfactory, or should I release the question to
see whether another Researcher can pin down a Glasser quote along
these lines?

I found the Rief attribution earlier, but need a source that includes
an actual study. One source attributed a 1988 pre-Glasser study on
this subject to the authors Ekwall and Shanker. This source would
actually be better than the Glasser one, which purportedly adds "and
95 percent of what they teach someone else".
I need the actual article containing a study, either by Glasser,
Ekwall / Shanker, or earlier.

Here's a reference to a 1987 study that might be of use:
"A point no educational psychologist would
dispute is that students learn more when information
is presented in a variety of modes
than when only a single mode is used. The
point is supported by a research study carried
out several decades ago, which concluded that
students retain 10 percent of what they read, 26
percent of what they hear, 30 percent of what
they see, 50 percent of what they see and hear,
70 percent of what they say, and 90 percent of
what they say as they do something (Stice
1987)
Stice, J.E. 1987. 'Using Kolb?s Learning Cycle
To Improve Student Learning.' Engineering
Education 77: 29 1-296."

Pinkfreud-ga,
I will accept this as an answer because you have provided a citable
source for the study and because this source leads to other citable
material.
Thank you!
