The Anatomy of an Education Myth

The Ten Percent Solution: Anatomy of an Education Myth

I came across this article the other day and think that it is worth re-posting on this blog. It has numerous applications undermining some of the assumptions people hold in churches and schools.

FOR MANY YEARS, VERSIONS OF A CLAIM that students remember "10% of what they read, 20% of what they hear, 30% of what they see, 50% of what they see and hear, and 90% of what they do" have been widely circulated among educators. The source of this claim, however, is unknown and its validity is questionable. It is an educational urban legend that suggests a willingness to accept assertions about instructional strategies without empirical support.

The Claim

In a popular book on children with ADHD, the author makes the following claim:

According to statistics, students retain:

10% of what they read;

26% of what they hear;

30% of what they see;

50% of what see and hear;

70% of what they say; and

90% of what they say and do." (1)

The claim is startling. Any instructional method that could deliver on a promise of 90% retention would revolutionize education. Moreover the claim is framed with impressive exactitude. The reader would like to know more but, alas, no source is given other than "statistics." The figures are passed along like memes. A book on accelerated learning, for example, claims:

It has been said that on average, we remember:

20% of what we read

30% of what we hear

40% of what we see

50% of what we say

60% of what we do

90% of what we see, hear, say, and do" (2)

But no source is acknowledged and no evidence is given. A slightly different version of the claim is presented in a recent issue of the Stanford Business Review: "Some research on learning indicates that we may retain only about 10% of what we read, maybe 20% of what we see and hear in a lecture, and perhaps 80% of what we experience
personally. Learning may increase even more to the extent that we take what we have experienced, put it into our own words, and then explain it to others." (3) But just what is this research and who conducted it? On this point the article is silent.

An Internet search reveals dozens of versions of this claim. While they are all essentially similar, they often differ in the specific percentages they assign to the various instructional modalities. For example "20% of what they read" is far more common than "26% of what they read." Some versions add the final claim that students retain "95% of what they teach to someone else." What is the origin of this claim and why have educators accepted it uncritically?

The Source

To date, all efforts to locate the source of this claim have failed because all trails have led to dead ends. For example, a 1988 paper by Felder and Silverman repeats the claim and cites a 1987 paper by Stice as their source. (4) The Stice paper in turn speaks of "some data from the old Socony-Vacuum Oil Company. (The source indicates the data are from the 1930s or 1940s, but I have no other information)." (5)

A 1997 paper by Lee and Bowers, however, sets out on an alternative trail. These authors indirectly cite White (sic) from a 1992 paper by Hapeshi and Jones. (6) The passage in Hapeshi and Jones actually reads:

Bayard-White (1990) quotes the British Audio Visual Society, which claimed that we remember about:

10% of what we read

20% of what we hear

30% of what we see

50% of what we see and hear

80% of what we say

90% The evidence of what we say and do at the same time

The evidence for these statements is not given ..." (7)

Thus Lee and Bowers cited Hapeshi and Jones, who in turn cited Bayard-White who, they acknowledge, had no evidence for the claim. An Internet search for the "British Audio Visual Society" yielded a total of 9 hits, all of them repeating the claim and citing this organization as its source. But no record of the existence of a British Audio Visual Society has been found. It appears that once a claim has been published subsequent authors do not bother much about the actual supporting evidence.

A third source frequently cited for the claim is Edgar Dale. In fact, many on-line versions label the claim "Dale's Cone of Experience," or "Dale's Cone of Learning." In his 1946 book, Audio Visual Methods in Teaching, Dale did present a concept called the "Cone of Experience." described as "merely a visual aid to explain the interrelationship of the various types of audio-visual materials, as well as their
individual positions in the learning process." (8) In the 1969 edition of Audio Visual Methods in Teaching Dale tells us:


In addition, we have suggested the narrowing
upward shape of the Cone does not
imply an increasing difficulty of learning.
Both verbal and visual symbols are used by
little children, Demonstrations may be complex
and quite involved--much more a)
than a map (a visual symbol) of Alaska.
The basis of the classification is not difficulty
but degree of abstraction--the amount of
immediate sensory participation that is
involved. Thus, a still photograph of a tree
is not more difficult to understand than the
dramatization of Hamlet. It is simply in itself
a less concrete teaching material than the
dramatization. (9)

Dale's Cone is really a classification of audiovisual material on a scale of abstractness and bears only slight resemblance to the claim. Indeed, it could be argued that Dale's Cone presents a much more complex model that is trivialized when associated with the claim. All citations of Dale as the source of the claim are simply mistaken.

The Truth

I was only able to locate one paper that explicitly tested the claim, the research by Lee and Bowers who found:


These results do not support White's(sic) percentages
for the contribution of the different components
of multimedia (as quoted in Hapeshi & Jones,
1992). For example, audio did not have a larger
impact on learning than text, nor did graphics and
animation alone have a larger impact than audio
(unless one is comparing "what we see" as text and
graphics together. Actually, audio had much less of
an impact and audio plus graphics and text plus
graphics had an equivalent impact. (10)

Nor does the claim agree with other empirical studies of the relative
effectiveness of various teaching techniques. (11)

The Meaning

In his investigation of the myth that people use only 10% of their brains, Barry Beyerstein noted a similarity to urban legends because "attempts to verify them invariably lead to an infinite regress." He also argued that there is a connection between numerology and the 10% brain myth: "I suspect that the lucky choice of the number 10 for the denominator in our fictitious fraction has served to enhance the
attractiveness of" the one-tenth myth. Among magical thinkers, numerology--the belief in the magical power of numbers--is rarely far from the surface, and 10 is a perennial favorite in this camp. Probably because nature equipped us with 10 fingers and 10 toes, our ancestors developed a primitive reverence for them." (12)

Beyerstein goes on to give examples of how arbitrary increments of 10 are often given special significance such as the Ten Commandments, the 10 best dressed list, and the characterization of historical periods in terms of decades. The educational claim investigated in this paper is typically flamed in increments of 10, and thus fits neatly into this pattern.

A recent paper by Simkin and Roychowdhury estimated that a large percentage of authors do not actually read the papers they cite. (13) As worrisome as their findings are, the multiple iterations of the claim reveal an even more distressing pattern. Not only do people often fail to read the research they cite, they sometimes fail to see if the research was ever actually conducted!

Above all this suggests a staggering lack of curiosity and a willingness to accept findings that agree with superficial preconceptions. Perhaps the real world effects of the claim examined here are relatively benign. After all, who would quarrel with the idea that instructors need to use a variety of teaching techniques? But the
larger implication is troubling. Instructional techniques affect real children, and education have a responsibility to ground their practice in actual research, not unsupportable cliches.

Miraculous . . . or Marvelous?

Epiphany II
John 2:1-11

(An audio version of this can be found here and clicking on "Stream.")

On the third day there was a wedding at Cana in Galilee, and the mother of Jesus was there. Jesus also was invited to the wedding with his disciples. When the wine ran out, the mother of Jesus said to him, “They have no wine.” And Jesus said to her, “Woman, what does this have to do with me? My hour has not yet come.” His mother said to the servants, “Do whatever he tells you.” Now there were six stone water jars there for the Jewish rites of purification, each holding twenty or thirty gallons. Jesus said to the servants, “Fill the jars with water.” And they filled them up to the brim. And he said to them, “Now draw some out and take it to the master of the feast.” So they took it. When the master of the feast tasted the water now become wine, and did not know where it came from (though the servants who had drawn the water knew), the master of the feast called the bridegroom and said to him, “Everyone serves the good wine first, and when people have drunk freely, then the poor wine. But you have kept the good wine until now.” This, the first of his signs, Jesus did at Cana in Galilee, and manifested his glory. And his disciples believed in him.

The apostle Paul writes: “For Jews demand signs and Greeks seek wisdom, but we preach Christ crucified . . .” (1Cor. 1:22-23). The Gospel appointed for today seems to have a little something for everyone. For Jews demanding signs we have Jesus changing water into wine. For Greeks seeking wisdom, we have a little moral of the story: “Save the best for last.” But what’s in it for those who are looking for Christ crucified? What’s in it for those who are not merely looking for miraculous manifestations or for a revelation of common sense?

It is really no big deal for Jesus Christ, true God and true man ,to be changing water into wine. What could be more simple for the One by whom and through whom all things were made? Why, if He wanted to, He could turn YOU into a stone jar of fine wine — or a pillar of salt.

The marvelous epiphany in this text is not that Jesus did a miracle, but rather that the Lord God Almighty should have anything to do with the cares and concerns of sinners. When His mother expressed a need, Jesus replied, “Woman, what does this have to do with Me?”

Are you looking for Jesus to do something for you — something miraculous perhaps? Do you call on the Lord God Almighty to get you out of a jam, to make you feel better when you are in pain, to grant you success in the face of failure? What does that have to do with Him? Why should He care? As the Psalmist wrote, “What is man that you are mindful of him, and the son of man that you care for him?” (Ps 8:4) Or as the prophet Isaiah wrote (Is. 40:17), “All the nations are as nothing before Him, they are accounted by Him as less than nothing and emptiness.” By comparison, if you went to the mayor and said, “I’m broke,” what would that mean to him? If you went to the state rep or governor or president on up the line to the Lord God Almighty, what makes you think they would care?

Jesus shows that the Almighty God has something to do with us. Ultimately, it isn’t what is miraculous. It’s what is marvelous. It isn’t changing water into wine. It’s when His hour comes. When in this text Jesus says, “My hour has not come,” He is pointing to what lies ahead. That something is noted later in the Gospel of John (17:1), in Christ’s prayer in the Garden of Gethsemane, “Father, the hour has come; glorify your Son that the Son may glorify you.” And again in the Gospel of Mark, “The hour has come. The Son of Man is betrayed into the hands of sinners.” (Mark 14:41)

God didn’t send His Son into the world to do miracles. He gave His Son for the forgiveness of sins. If the Church were about doing miracles every Sunday . . . but no. He forgives sins every Sunday. And we act as though that were boring.

Like a teenage daughter who wants an expensive prom dress and is told “No.” She throws a fit and accuses her parents of not loving her. She doesn’t consider the fact that she has a roof over her head, food to eat, clothes to wear, free taxi service, an ATM machine that looks like her mother’s purse or her father’s wallet. All of that is boring.

Christ crucified is the ultimate epiphany in which God reveals that He has something to do with us. There is no miracle on the cross; only what is marvelous. On the cross Jesus says, “I have something to do with you. Your sins I atone for with My own blood. Your lying and your self-centeredness and your disrespect I atone for with My innocent suffering and death.” If God has not spared His only begotten Son, will He not give you all good things?

Jesus shows that He has something to do with us today where He joins His body and His blood to bread and wine according to His word. At this Lord’s Table this morning, there is no miracle going on. As Lutherans, we categorically deny both transubstantiation and consubstantiation, that the bread is changed into Christ’s body or that the wine is changed into His blood. That would seem miraculous. In fact, the magical term “hocus pocus” comes from a misunderstanding of the Lord’s Supper. The Latin, which few could understand, was “Hoc est corpus meum” or “This is My body.”

We do not practice miracles here in this sanctuary. We are stewards of what is marvelous. Jesus unites Himself with us, meets us, cares about us in this blessed communion. Whether we run out of food or money, and when it seems as though we are of no concern to Him, we live by faith not by sight. “Lord, it seems like You’re not going to have anything to do with me. But I know better. You took on this flesh. You suffered and died for my sins.” Cast all your cares upon Him, for He cares for you. Worries, anger, sins. Bring them here. He has something to do with them. Another Krueger child . . . Amanda . . . Alexandra, Annabel, Abigail, Cast cares.

Confident of this marvelous fact, knowing that the Lord God Almighty has something to do with us in a gracious way, we in turn may ask others “What have I to do with you?” Whether it be to tsunami victims or our military abroad or children in the school, we are a concern to each other. We are no longer anxious for ourselves. We are anxious for each other. Jesus has something to do with you. Now you have something to do for others.

We have not gathered here this morning for Jesus to do miracles. We are not gathered here to get some interesting perspectives on life or Ben Franklinesque helpful advice for living. We are here because it is marvelous in our eyes that the Lord God Almighty should have anything to do with us. Therefore, do not look for a miracle as proof of God’s love for you. Look to what is marvelous, the innocent suffering and death of God’s Son, our Lord Jesus Christ. Amen.

Christmas Gifts


"And when we give each other gifts in His name, let us remember that He has given us the sun and the moon and the stars, and the earth with its forests and mountains and oceans--and all that lives and move upon them. He has given us all green things and everything that blossoms and bears fruit and all that we quarrel about and all that we have misused--and to save us from our foolishness, from all our sins, He came down to earth and gave us Himself."

The Origins of the Name Noel

I had heard that people weren't certain of the origins of NOEL - and the explanation on Wikipedia seems a bit convoluted.

The thought occurred to me that it could be a simple abbreviation of the last four letters in IMMANUEL.

The WAW (a Hebrew letter) can express both "U" and "O". A little child or someone not entirely familiar with Hebrew or Biblical pronunciations might certainly shorten it this way.

Immanuel: Born is the King of Israel.
