Intelligence and Education
There are numerous ways to measure intelligence in education. Each methodology provides a glimpse into whether a student could be considered intelligent; however, it is only a glimpse. For each intelligence measurement, there are numerous arguments about what is NOT measured. This post discusses three intelligence measurements and attempts to show the relationship among them.
The first measurement is the Intelligence Quotient (IQ) and how it is distributed along a traditional bell curve. The next measurement is Emotional Intelligence (EI) and how it is complementary to IQ. Finally, Multiple Intelligences (MI) and how there is more than one way to measure intelligence are presented. According to Herrnstein and Murray, “In everyday language, people who are called very smart tend to have high IQs” (1994, p. 21). Because this is such a common way to determine intelligence, this post begins with IQ.
Finding a Place on the Bell Curve
When it comes to measuring intelligence, researchers are looking for a way to distinguish smart people from not-smart people. Herrnstein and Murray believe that “…high intelligence has earmarks that correspond to a first approximation of the commonly understood meaning of smart” (1994, p. 21). Based on this belief, IQ, as a measure of analytical intelligence, can be distributed among the general population along a traditional bell curve.
In Herrnstein and Murray’s book The Bell Curve (1994), the authors define cognitive classes of IQs along a normal distribution. Those who are in Category I are considered very bright and fall above +2 standard deviations. Those who are in Category II are considered bright and fall between +1 and +2 standard deviations. Those who are in Category III are considered normal and fall between -1 and +1 standard deviations. Those who are in Category IV are considered dull and fall between -1 and -2 standard deviations. Finally, those who are in Category V are considered very dull (a term preferred by the authors as being “less damning than the standard ‘retarded’” (p. 122)) and fall below -2 standard deviations. This would seem quite tidy if it were not for several glaring oversights.
While it is difficult for any researcher to exhaust a single topic, Herrnstein and Murray missed several important elements. Franz Samelson (1997) points out that at least three major historical references are not addressed in The Bell Curve. Those missing references would provide valuable supporting information for the reader. From these omissions (as well as from other oversights), Samelson believes that Herrnstein and Murray’s scientific objectivity “turns out to be an illusion” (1997, p. 132). Other researchers tend also to support this belief.
Robert J. Sternberg is one such researcher. Using a variety of references as evidence, Sternberg refutes seven of the book’s major claims (1996). One of his biggest arguments is that much of the study is merely an exercise in statistics. He writes, “Thus, the existence of a general factor [i.e., IQ] tells more about the statistical technique than it does about the mind” (p. 47). Sternberg is also correct in refuting many of the correlations in the book because correlation does not necessarily mean causation.
With as much controversy that surrounds the ideas presented in The Bell Curve, it is not surprising that other measurements of intelligence have emerged. One such measurement is Emotional Intelligence, which is presented in the next section.
A Curve Ball for the Bell Curve
If IQ measures cognitive intelligence, then Emotional Intelligence (EI) measures affective intelligence. Affective intelligence deals with feelings and sensations, both of an individual and of others. Emotional Intelligence is a way to determine if a person is smart about feelings.
Emotional Intelligence (EI) comprises five main domains (Goleman, 1995). The first is knowing one’s own emotions. The second is managing those emotions. Next is motivating oneself. The fourth domain is recognizing others’ emotions. Finally, the fifth domain is handling relationships. More recently, Goleman has split EI into two elements: Emotional Intelligence and Social Intelligence (2006). Goleman states, “…simply lumping social intelligence within the emotional sort stunts fresh thinking about the aptitude for relationship, ignoring what transpires as we interact”(p. 83). Both Emotional and Social Intelligence relate to the affective domain, and it is important to determine how to educate the affective domain.
There is value in educating the affective domain. Addressing the emotions of others is beneficial to society. According to Sherlock (2002), “The thinking-feeling-doing model is an educational process that would lead to greater understanding of others in the global community” (p. 146). Not everyone holds this same view. At the very least, not everyone believes that EI can be a predictor of success.
As a measure of intelligence, EI may not be able to predict an individual’s future success. Based on a study conducted by Barchard (2003), “The cognitive ability domain and the personality domain do a far better job at predicting academic success” (p. 856). Much like IQ, EI is a one-dimensional measurement. It cannot be used alone to determine if someone is smart or if that person can be successful. There are arguments against these findings as well.
One key argument for EI is that more recent research does indeed show a connection between EI and success. Much of the research has been done in the workplace environment instead of in the academic environment (Cherniss, Extein, Goleman, & Weissberg, 2006). In addition, there has been clarification about the relationship between IQ and EI: “Goleman proposes that EI abilities, rather than IQ or technical skills, will better discriminate those who will be most capable in top positions” (p. 242). Nevertheless, both intelligences are necessary.
In essence, IQ and EI are opposite sides of the same coin. By measuring both IQ and EI, a more accurate indicator of a person’s being smart could be obtained. Nevertheless, that still does not provide a complete picture. A person can be smart in still other ways. Gardner’s theory of Multiple Intelligences provides yet another way to measure intelligence.
Flattening the Curve with Multiple Intelligences
No one can deny that IQ and EI each provide a way to measure intelligence. Specifically, they measure analytical and affective intelligence. If someone is analytically intelligent, that person is considered smart. Does this mean that those who are not analytically intelligent are not-smart? That depends on the measurement and on the underlying meaning of the measurement. Because of this subjectivity, other measurements of intelligence, including Gardner’s theory of Multiple Intelligences, have emerged in an effort to flatten the curve.
Gardner’s theory of Multiple Intelligences includes seven ways in which intelligence can be measured. Those seven include musical intelligence, bodily-kinesthetic intelligence, logical-mathematical intelligence (similar to analytical intelligence), linguistic intelligence, spatial intelligence, interpersonal intelligence, and intrapersonal intelligence (1983). These last two are similar to affective intelligence. This is far more encompassing than IQ and EI combined. (It is interesting to note that Herrnstein and Murray called Gardner a “radical” (1994, p. 18).)
Since Gardner’s original theory was published, an eighth intelligence has been added. It is naturalist intelligence (Smith, 2008). While other intelligences have been proposed over the years, they have not been added to Gardner’s theory of Multiple Intelligences because of their flaws. Even the eight intelligences that Gardner supports have their own problems.
One of the biggest problems with the theory of Multiple Intelligences is assessment (Gardner & Hatch, 1989). In order to assess students who are taught using MI, it is not enough to construct yet another analytical test. Instead, a means for providing an “intelligence-fair” method for assessment is necessary (p. 6). Even with such assessments, it is unlikely that any one assessment could determine if someone is smart in any one intelligence. Instead, it is more likely that the assessments could show either strength or weakness in the intelligences (Gardner & Hatch, 1989). This problem of assessment has led to numerous critiques of MI.
One major critique of MI is that it is not based on empirical evidence. Gardner refutes this by writing, “This nonsensical view could not be held by anyone who has ever spent more than five minutes skimming through the book” (1996, p. 2). Another common critique of the theory is that it is attractive because of what it opposes, like standard psychometric tests. Instead, Gardner believes that the theory should not be attractive for what it is not, but for what it is: more than a “one-dimensional approach to students” (p. 2).
There are eight intelligences from which to choose. In addition, as these eight intelligences cannot measure if someone is smart, only if he or she has strength or weakness in any of the intelligences, it is conceivable that everyone has his or her own strengths and weaknesses. This is a notion that is far more compelling than simple smart and not-smart labels.
Conclusion
It is evident that there are numerous ways to measure intelligence. Each methodology presents only a small way in which intelligence can be measured, and not one of them can determine whether a person is smart. This post has presented three intelligence measurements and has shown the relationship among them.
First, the Intelligence Quotient (IQ), as plotted on a bell curve, was presented as a very narrowly focused, one-dimensional way to measure intelligence. Next, Emotional Intelligence (EI) was presented as the softer side of IQ, yet it was still one-dimensional. Finally, the theory of Multiple Intelligences (MI) was presented. It is this final theory that seems to encapsulate what should be most important when considering intelligence in education: everyone is smart in his or her own way.
