What are the aims of a high school curriculum? Getting to a clear answer is the necessary first step in rethinking a school’s curriculum. But to commit oneself, as Essential Schools do, to the idea that the goal of education is to get students to use their minds well is to take the deceptively simple first step in rethinking our entire system of education.
Evidence of how difficult this proves is apparent even among the Coalition of Essential Schools. The governing metaphor of student as worker is accepted among all Essential Schools. But few are taking the necessary and frightening next step–to redesign the entire curriculum around thorough coverage of fewer areas, rather than offering an array of courses aimed to attract students for whom vastly different expectations are held. Why this should be so is a fascinating and deeply political question, best explored by looking, in theory and in practice, at what that studentworker is doing in the Essential School classroom.
Authentic Work
What, for instance, does it mean for a student to “work” in such a class? Clearly it does not mean to take assiduous notes as a teacher delivers instruction from the front of the room. The fifth of the common principles Coalition schools embrace suggests that teachers, instead, act as coaches–“to provoke students to learn how to learn, and thus to teach themselves.” This kind of “authentic” student work is active and collaborative; it has evident value and clear goals, and it generates more ideas, connections, and challenges the more it is pursued.
Authentic work, says Coalition research scholar Grant Wiggins, who has studied the pedagogy of Essential Schools, meets these and other very specific standards. When students are really workers, Wiggins says, they can always answer certain questions–about the task’s purpose, about the resources needed to carry it out, about what it means to do the task well. They can grasp what is essential about the task, set priorities, make intelligent judgments. Ideally, this is true not only at the level of a particular assignment, but also when applied to all the courses in a curriculum, taken together. Students should emerge from their high school career with an integrated vision of how to think within the culture, which implies a broad understanding, not just narrow or rote expertise.
This way of looking at work contrasts directly with the traditional pedagogy of American secondary education. For a century high schools have asked students to memorize facts and answers in carefully distinct fields of study; and teachers have been under pressure to design courses that cover a specific chronological sequence of material. This emphasis on coverage in the curriculum inevitably focuses attention not on how to learn or think, but on what facts one “needs” to know, presented once only in a linear “run” through four years of school. But what one “needs” to know depends, as David Cohen forcefully argues in The Shopping Mall High School, on what one’s future role in the social structure is seen to be. The fragmentation of the curriculum into subjects, levels, and purposes that will appeal to every student reflects the historical role of American high schools less as centers of learning than as holding places for people whose place in the social and economic structure is not yet ready for them. Except for a few at the top, whether or not our students learn to think has not been the point at all.
Questions, Not Answers
The alternative, to adopt thoroughness in place of coverage as the guiding principle of a curriculum, rests on the Coalition’s conviction that every student can come to think critically. But where might an individual teacher begin? The starting point, as Grant Wiggins argues, is to “organize courses not around ‘answers’ but around questions and problems to which ‘content’ represents answers.” Such “essential questions,” as they are known, are an important ingredient of curriculum reform as the Coalition of Essential Schools sees it. On every level–from the most encompassing, schoolwide questions to the specific question posed in a particular unit of a particular course–the “essential question” should shape the way students learn to think critically for themselves.
At Central Park East Secondary School in New York City, for example, the entire curriculum is focused on getting students to ask and answer questions like these: “From whose viewpoint are we seeing or reading or hearing? How do we know what we know? How are things, events, and people connected to each other? What in this idea is new and what old? Why does this matter?” (See Figure 1.) When they are applied at the course level, such questions consistently engage students in what Benjamin Bloom calls “higher order thinking”–analyzing, synthesizing, and evaluating evidence they gather themselves.
For example, a Central Park East U.S. history class focusing on immigration centers around a more specific “higherlevel” essential question: “Whose country is this, anyway?” That question shapes the materials and activities that will guide student research into smaller, unitlevel questions, like “What factors motivated people to uproot themselves and come to this country?” or “Are there ethnic differences in these factors?” By exploring the political, economic, and social forces that shaped American immigration from its beginning–and by asking at every point the guiding “schoolwide” questions–students gain a critical understanding of the content of U.S. history, rather than memorizing a set of facts or someone else’s interpretation of what those facts mean.
Unitlevel questions serve as what Grant Wiggins calls “entry points” to larger questions that can go to the heart of a discipline. Because they take shape as projects, case studies, or simulations, they get students under way quickly, making inquiries that lead to the essential facts and theories the course will cover. And they evoke these abstract and complex issues in a concrete setting with which students are already familiar.
Teachers throughout the Coalition are coming up with questions like this, to serve as entry points in every discipline. CES’s Assistant Director for Schools, Amy Gerstein, has a file full of examples teachers have developed, often in the summer workshops the Coalition sponsors. Teacher Priscilla Winn Barlow, for instance, asks students in a botany unit the essential question, “What is life, growth, ‘natural’ development? What factors most influence healthy development?” (See Figure 2.) Her entrypoint questions are more specific, such as: “Do stems of germinating seedlings always grow upwards and roots downwards?” To answer this last, students must devise an experiment, and eventually come on their own to a definition of what tropism is. The unit continues with questions designed to evaluate what environmental factors plants respond to, and how.
In the example above, the “essential question” about growth is undeniably a higherlevel question. To answer it, students must combine information they find in books with information they acquire through their own experimentation. Because they must come up with their own hypotheses to test, they also gain important skills in creating experimental situations that allow them to reason from observation.
Such entry points can lead directly towards key unifying theories at the very center of math or science. For instance, firstyear algebra students could learn to factor polynomials by discovering the relationship between multiplication and factorization through a series of entrypoint questions. (See Figure 3.) “Given a quadratic polynomial,” workshop participant Robert Cornell asks, “can you find whether it can be rewritten in factored form by actually finding the factored form?” After students come up with techniques to do this, Cornell asks an even more pointed question: “When a polynomial is rewritten into factored form, what facts do you know about the polynomial that you didn’t know before?” At its essence, this question leads to what mathematicians and scientists must struggle with at the highest level: whether or not two apparently different phenomena reflect the same deep fact about the world.
Asking questions as a way of organizing content also serves to strengthen students’ sense of their own authority over the content. Through their work they become experts on one aspect of a problem, and learn to collaborate with other students in the exchange of important facts. This “jigsaw approach” is described in the unit on AIDS developed by Grace Taylor at Brown University (see Figure 4). Noteworthy in this assignment is the extent to which discipline lines must be crossed to master the material, and the fact that different kinds of intellectual skills are developed. In the process of doing their research the students will learn about social studies issues, and also about important biology matters like contagion and the nature of viruses. But they will also be mastering the more general skill of critically analyzing the various texts they use.
To do well in a unit called “HomoInsectivorous and the Dilemma of World Hunger” developed at one summer workshop by teachers Sandy Ohlerich, Dana Minoya, and Kent Vierot (Figure 5), students must also master such collaborative skills. As well, while they research whether eating insects could be a solution to world hunger students must become familiar with content in a range of disciplines from political economics to biology, entomology, and human nutrition. Finally, they must learn something about speech and rhetoric to prepare a persuasive presentation to the class.
Each entry point question will have its own specific ways it encourages students to use their minds well. Some questions will tilt in the direction of content mastery, others towards the development of higherorder thinking skills like deductive reasoning. By actively carrying out such assignments students are learning different kinds and levels of intellectual skills all at once.
The Teacher’s Role
It’s easy to see how a questioncentered approach could radically change the way a teacher designs a particular course. Rather than moving from point A to point Z, the teacher encourages students to learn key skills through which content can be revealed. “Instead of merely ‘covering’ material, students UNcover and REcover important ideas in context,” says Grant Wiggins. “No essential idea, fact, theory, or application can be learned by doing something ONCE.” Wiggins compares such learning to the ways in which ball players or musicians master their skills–they learn new rules and strategies as they need them, not in “logical” order; and they make such essential skills habitual by practicing them again and again.
If the analogy is carried further, the teacher’s role as coach becomes even clearer–to make herself gradually obsolete as students learn to solve problems for themselves. This attitude extends also to the textbook, which the student learns to use as an intellectual resource for research, not a program to be rigidly followed in sequence.
Most Essential Schools, CES’s Director for Schools Bob McCarthy says, are already well on their way to shaping course work around such essential questions. In the classroom with the door shut, an individual teacher can often make these fundamental changes in approach without anyone even noticing. But it isn’t long before new pedagogy begins to rub up against the structure of the traditionally designed curriculum. Specialtopic coursestrigonometry, for instance, or economics, or American literaturemay be too confining for the questioncentered logic of Essential School pedagogy; if essential questions are posed within them, what students need to learn will necessarily reach far beyond the conventional limits of the course. At this point, if teachers are not actively sharing this approach among themselves and if the overall school curriculum does not reflect it, trouble can start to brew.
What About Assessment?
The matter of assessment is the first to present itself. The conventional curriculum is closely tied to standard measures of what it means to do well in our society–competency tests, SAT scores, college acceptance, and more. If a school is in desperate academic straits–low scores, high dropout rates, few going on to college–it might well consider a wholesale shift in its curriculum to reflect more thorough coverage of fewer areas. A school like this has little to lose and everything to gain by teaching students to use their minds well.
But what of a more conventionally successful school, where “all the tests” show that students are doing just fine, and whose students often gain admission to the most prestigious colleges? What incentive does such a school have to reexamine its curriculum and methods? The problem here, Coalition chairman Ted Sizer points out, is that few of those tests are designed to measure critical thinking. “The fact is that most ‘successful’ students can’t stand up to two Socratic questions in a row,” he says. And it is common knowledge among professors at even the “best colleges” that students coming into them have serious weaknesses in their ability to think critically or creatively.
The inadequacy and even harm of testbased criteria of educational success is further borne out, Sizer notes, by the epidemic of cheating most high schools nationwide are experiencing. If to succeed in school means to do well on such tests, a student can succeed on everyone’s agreed terms not by thinking well but by outsmarting the tests–by either memorization or cheating, or both. The entire curriculum is designed to meet the standards measured by those tests–so a student can progress through four years of high school and go on to college without ever being required to demonstrate that he can use his mind well.
In fact, most schools remain wedded to the assumption that the mere passage of four years’ time is the governing principle behind the curriculum. That assumption, Sizer says, is “bureaucratically useful,” but illdefined and indefensible. The ideal curriculum, he says, is like a trip the student takes, going at different speeds during different periods. Students leave school only when they arrive at the end of the trip–by demonstrating mastery in the form of a final exhibition.
It is worth looking at what goals the standard high school curriculum does serve. Historically, as The Shopping Mall High School points out, thinking well has almost never been one of high school’s aims. Our current curriculum, instead, results directly from explicit social and economic policies over the past hundred years, aimed to keep young people out of the job market and off the streets. Based on a deep cynicism about who CAN learn to think, our educational system defines success in different ways depending on who you are. For some, success in high school will simply equal not getting into trouble before they finish.
The standard curriculum is perfectly matched to those often unarticulated goals. Courses form a kind of checklist–two years of math, three years of English, one year of history–that students tick off as time goes by. A wide range of course options is available to “shop” from, and students are tracked into the ones that will fit their future station in life. Teachers and students agree implicitly that subject mastery is less important than getting through one course and on to another, so course expectations are set accordingly low. Not by coincidence, teacher training reflects the same values–potential teachers rarely have true mastery of their subjects, and the methods they learn rely heavily on textbookdriven pedagogy.
For a school to decide it wants to abandon these goals, and move instead to another vision of teaching all its students to use their minds well, has deep political consequences. It is threatening to teachers, who must give up thinking of themselves as deliverers of information; and it threatens the assumptions that underpin the socioeconomic stratification of our society. Little wonder that to move towards a schoolwide curriculum reflecting the belief that “Less is more” is a step so hard to take. In the Coalition, the schools that have attempted it are almost without exception the ones directly seeking to empower students who might not otherwise succeed.
Needed: New Assessments
It may be too early to tell whether teaching all students to think critically can also result in higher scores on the standardized tests by which we currently measure success. The sense at the Coalition is that it will, even if only because students will be able to analyze the test questions. But more important than living up to current, inadequate assessment instruments is designing new kinds of assessments that can show students actually working to solve problems on their own.
In this light, the final exhibitions of mastery the Coalition advocates –examples of which Grant Wiggins has spent the year collecting–are integral to the redesign of a curriculum around essential questions. A school must make its alternate vision of success quite explicit–by saying clearly what students should be able to know and do by the time they graduate, and by holding to its exhibition as a test of a student’s success. “The shadow cast backwards from that finding should be the curriculum,” Ted Sizer says.
Any consideration of curriculum change, therefore, must begin with an essential question for educators: “What do we really want?” What would it be to imagine a curriculum based on mastery of knowledge rather than chronological coverage of facts? What if questions were encouraged to be asked that linked several subjects together in a larger context, rather than making arbitrary divisions between areas of study? What if teachers were to communicate with each other, sharing their goals and methods freely and integrating them into each other’s courses? What if we held to the vision that all students can learn to think well? When a school’s curriculum manages to respond to these questions, we will have before us a true exhibition of mastery, and its benefits will be possible at last to chart.

Figure 3: A Project in Factoring for FirstYear Algebra Students1. The factoring process is the inverse of the multiplying process, yet many students see the two processes as separate from one another. Many algebra texts have one chapter called Multiplying and another called Factoring; many teachers present polynomial multiplication, test that, and then present polynomial factorization. Through this separation, many students often miss concepts such as what it means for a polynomial to be in factored form and what the relationship is between multiplication and factorization. Finally, much of a student’s time is taken up with the mechanics of factorization. This time focuses on the fringe of the topic rather than the essence of factorization. This section will concentrate on quadratic expressions. 2. The essential question is “Given a quadratic polynomial can you find whether it can be rewritten into factored form by actually finding the factored form?” 3. When students can multiply binomials with ease, have them write the results of multiplications such as the following:
Erase the original multiplication problem leaving just the correct answers. Now ask the students to see if they can recreate the original problem. They should be able to find a multiplication problem that yields the answer. 4. How many techniques can a class come up with to find the original factored form of the polynomial?
