On paper, Celia fell somewhere in between. She was good on almost every traditional measure of success but not outstanding on any one. But rather than fall somewhere in the middle of her class at Yale, Celia proved to be a standout. Her talent was adapting well to the demands of her new environment and figuring out what was expected of her. She was, in other words, "street smart,'' Sternberg says.

Most educators know students like Alice, Barbara, and Celia. Sternberg, however, coupled his experiences with these students with extensive readings in psychology and other fields and came up with what he calls his "triarchic theory of intelligence.'' In simple terms, it holds that intellectual ability takes different shapes--not all of which are captured by the traditional means schools use to measure it.

In addition to Alice's analytical kind of intelligence, Sternberg suggests, people also possess creative intelligence, which allows them to cope with novelty, and practical intelligence, which enables them to apply what they know to everyday situations.

Sternberg is neither the first nor the most well-known psychologist to say that intelligence takes on many forms and functions. Harvard psychologist Howard Gardner's "theory of multiple intelligences,'' for example, has met with much more receptive audiences in schools across the country. Both theories, though provocative, are not universally accepted. Together, however, they have opened up broader ways for educators to think about what it means to be smart and how they can help students reach their fullest potential.

The classical view holds that intelligence is an inborn trait that remains fixed over time and can be measured by means of an "intelligence quotient''--or "IQ''--test. Even as a boy, Sternberg questioned this long-held belief. His disenchantment began when the school psychologist administered an IQ test to his 5th grade class. Seeing the other children move quickly from one item to another, Sternberg panicked and fared poorly on the exam. When the test was administered the next year, Sternberg was sent from his 6th grade classroom to take it with a group of 5th graders. Less intimidated by these younger students, he breezed through the test, and his score improved considerably.

"I guess a lot of what I do comes from my own insecurities,'' the 44-year-old psychologist says now. In fact, he has spent the last 20-odd years exploring the subject.

What he has come up with suggests that intelligence is not fixed but, rather, something that is mediated through the environment and can be taught and enhanced. IQ tests, he says, measure only one form of intelligence--a form that is key to success in school but not necessarily key to success in the real world.

"Both Sternberg and Gardner are 'contextualists,' '' says Stephen Ceci, a Cornell University psychologist. "Both believe what we call intelligence isn't all inside the head. Much of it is outside the head, and the environment changes the way people deploy their intelligence.''

Gardner's multiple-intelligence theory holds that intelligence takes seven different forms: linguistic, musical, logical-mathematical, spatial, bodily-kinesthetic, intrapersonal, and interpersonal.

Sternberg, however, suggests that musical ability and other such traits are really talents. He presents a more multilayered approach to the concept. "His theory is the most ambitious of all the theories of intelligence,'' Ceci says, "because he took into consideration a number of different corpora of scientific knowledge--cognitive science, developmental psychology, psychometrics.''

Beyond his three intellectual abilities--analytical, creative, and practical--Sternberg says people have preferences in how they use those skills and how they govern their thought processes. This is what Sternberg calls his theory of "mental self-government.''

Like the different aspects of government, people have different styles of thinking, he says. One individual, for example, might be "legislative'' in that he or she tends to think in terms of creating, formulating, imagining, and planning. Another's tendencies may be more "executive'' or concerned with implementing and doing. Still others may tend toward the "judicial'' and prefer to evaluate and compare.

Sternberg takes the analogy even further, saying that the four major forms of government--monarchic, hierarchic, oligarchic, and anarchic--offer ways to think about how different people govern their thought processes. An individual with "monarchic'' tendencies, for example, focuses on one thing at a time and sticks with it until it's done. The individual who tends toward the "hierarchic'' does well at assigning priorities to multiple tasks. The "oligarchic'' form of mental self-government allows for dealing with multiple goals, all of which are equally important. And, finally, the "anarchic'' thinking style favors multiple, flexible approaches and trying almost anything.

An individual's form of mental self-government can also lean to the "conservative'' or "liberal.'' He or she may be "global'' and focus on the forest, or "local'' and focus on the trees. He or she might prefer to be a "producer'' or "consumer'' of knowledge. A person may also have a combination of thinking styles, and those inclinations may vary over time and in different contexts.

But schools, Sternberg says, tend to reward only one kind of intellectual ability, analytical, and one kind of thinking style, the executive. What's more, he says, teachers tend to reward those students whose intellectual styles best match their own.

In one experiment designed to test that theory, Sternberg and his Yale colleague, Elena Grigorenko, selected 28 teachers from four different kinds of schools, ranging from a Catholic high school to a public elementary school. Using a questionnaire, the researchers first assessed the teachers' thinking styles. The survey asked the teachers to indicate the degree to which they agreed with such statements as "I want my students to develop their own ways of solving problems'' or "I like to follow instructions when I am teaching.'' Students' thinking styles were evaluated twice by different teachers using another questionnaire. Finally, students evaluated their own thinking styles using a third questionnaire developed for that purpose.

In classrooms where teachers' styles were more legislative, the most successful students, the researchers found, were those with similar tendencies. Teachers with judicial styles tended to give the highest grades to judicial students, and the highest-achieving students in executive-minded teachers' classes were themselves executive in orientation. "It's important for teachers to understand themselves,'' Sternberg says. "You have to first understand your own take on the world.''

Sternberg and other researchers have also completed preliminary studies looking at intelligence in a different light: Do students learn better when taught to their intellectual strengths?

To tackle that question, they focused on 65 11th and 12th graders from the mid-Atlantic region who were spending the summer at Yale taking a general psychology course. All had been identified as gifted using a test developed with the "triarchic theory'' in mind. In the mornings, the students attended the same general lecture. In the afternoons, however, they went to sections taught in different ways. One section emphasized analytical thinking, another creative thinking, and a third practical thinking. Students were given assessments, however, that equally emphasized all three kinds of abilities.

As Sternberg's hypothesis suggests, students judged to be gifted in creative and practical ways fared better when placed in sections that matched their abilities--even on test items that were not compatible for them. The analytically gifted students, however, did worse in sections suited to their skills. (Sternberg speculates that those students might have been less motivated because they had always done well in school.)

The basic message, Sternberg says, is this: "If you're taught in a style that's not a good fit, the conclusion you draw--and maybe your teacher as well--is that you're not competent.''

Sternberg has continued to mine other aspects of his theory over the years. Working with Gardner, Wendy Williams, and other researchers at Yale and Harvard, he has perfected a program to teach middle school students how to hone their practical intelligence, what Sternberg calls "tacit knowledge.'' The program, known as "Practical Intelligence for Schools,'' is scheduled to be published next year by HarperCollins. "Teachers have a wide array of expectations for students, many of which are never explicitly verbalized,'' he writes in a 1991 paper. "If students cannot figure out what these implicit expectations are, their performance in school may suffer year after year.''

Sternberg's explorations of intelligence and other human qualities have been chronicled in hundreds of articles and books. He was named one of the top 100 scientists in the country in 1984 by Science Digest and was selected as an outstanding American under 40 by Esquire magazine two years later. He headed the American Psychological Association in 1993 and has won 10 other distinguished awards from his peers.

But for all the accolades, Sternberg's is not the household name in schools that Gardner's has become. Ceci, the Cornell psychologist, says that's because Gardner has been more deliberate in translating his theory for teachers and promoting it. "He is most mindful of the needs of educators,'' he says.

Gardner himself says he has less patience for what he calls the ground rules of psychology. "I'm a psychologist but don't identify myself with the sort of intelligence mafia,'' he says. In fact, Gardner eschews intelligence testing of any sort, triarchic or otherwise.

But Gardner doesn't dismiss the work of his colleague Sternberg. "From the point of view of the average teacher, the differences between us are less than the differences between us and the old view,'' he says. "We are united in opposition to a view that is 100 years old.''

Still Sternberg's ideas on intellectual development have begun to reach a number of educators. One is Betsy Ratner, a teacher of gifted elementary students in Milford, Conn., who thinks Sternberg's theory is easier to understand than Gardner's. "When I put it Bob's way, in three parts,'' she says, "it's just more simplistic for me to comprehend how it all comes together.''

But from his vantage point just beyond the educational mainstream, Sternberg is wary of what he calls the "bandwagon approach'' to school reform. "Now there's a big rush to performance assessment, and it really drives me nuts because who are you benefiting now?'' he asks. "You're benefiting the kids who are more legislative, more liberal.''

"What you'd ideally do as a teacher is teach in different ways and help kids understand what they do well,'' he says, "but also understand the things they don't do well and work with students to try to figure out strategies for compensation and remediation.''
