Sam Wineburg & Jack Schneider: Why Benjamin Bloom Got it Wrong When it Comes to History
The magic of Bloom’s Taxonomy, that familiar classification system for levels of thinking (and hence learning objectives), was that teachers could close their eyes and picture it. And with a little help from entrepreneurial consultants, they didn’t need to close their eyes at all—posters of color-coded pyramids became a standard part of classroom decor. The taxonomy was lean and intuitive, but the image of the pyramid gave it staying power. “Knowledge” formed the wide and stable base. “Evaluation” was the terrain of intellectual mountaineers.
Never mind the fact that Benjamin Bloom, the influential University of Chicago education professor who died in 1999, never used a pyramid to illustrate his taxonomy, much less for the purpose of teacher professional development. What mattered was the taxonomy in practice. In a postwar world marked by increasing specialization and fragmentation, the taxonomy was an antidote to chaos. Thinking, despite the many disciplines it came in, could be assayed and rank-ordered according to Bloom’s levels. And there were only six categories, not 60. The taxonomy was easy to remember and easy to use, even more so when it was reduced to a pyramid.
There was only one problem. The pyramid was upside down—at least for the history classroom.
Knowledge of history, as those taxonomic pyramids imply, can function as a platform upon which students can stand to make judgments. But just as math is about more than learning theorems, history is about more than collecting facts. It is also a discipline that requires piecing together an accurate story from incomplete fragments. Historical thinkers begin by asking questions, evaluating what they don’t know in pursuit of their ultimate aim: knowledge. And then they repeat the process.
But in thousands of history classrooms across the United States, that isn’t what happens. Students work to learn the names of people, places, and events. Only then, once they’ve built up a storehouse of knowledge, are they asked to think about it. When asked about such practice, many teachers find succor in Bloom’s Taxonomy. As one we interviewed noted: “I want kids to engage in critical thinking, but you can’t think about nothing. You need a data base to get to all those higher-order places—analysis, synthesis, evaluation.”
Without question, plugging up gaping holes in students’ background knowledge is how many savvy history teachers begin each new unit. But many teachers we interviewed assumed that learning the kind of information found in worksheets paves the way to higher-order thinking. That isn’t what we’ve observed.
One particular case is instructive. Over the course of 2½ years, our research team followed 17-year-old Jacob, an Advanced Placement student at a private high school. In one interview after the AP U.S. history exam (on which he scored a 4 out of a possible 5), we gave Jacob a document and asked him to read it “historically,” articulating what he thought the piece was about, raising questions about its historical circumstances, and sharing insights about the text.
In history, as in other disciplines, the aim is not merely to collect what is known, but to learn how to think about problems in a new way.
The document was a proclamation by President Benjamin Harrison in 1892. “Discovery Day,” as Harrison called it, honored Christopher Columbus as a “pioneer of progress and enlightenment.” In the schools, in the churches, and in “the other places of assembly of the people,” Harrison wrote, “let there be expressions of gratitude to Divine Providence for the devout faith of the discoverer.”
Jacob’s response to the document was deeply revealing. “The first thing that jumps out,” he noted, “is that Columbus is a pioneer of ‘progress and enlightenment.’ ” But Jacob had his own opinion: “From what I’ve learned, his goals were not entirely noble. Just get rich, whatever; … he claimed to be a true Christian, but he also captured and tortured Indians, so he wasn’t maybe as noble as this is having him be.”
This response, typical among the group of AP students we interviewed, is in many ways ideal. Jacob marshaled background knowledge about Columbus and worked his way toward the Bloomian peak, eventually challenging President Harrison’s praise for Columbus with his own critical alternative. His response, though unpolished and in need of elaboration, seems like critical thinking. And that’s how the teachers we interviewed generally saw it. Nice job, Jacob.
But then we asked a group of history graduate students what they saw in the document. And they saw something totally different. To them, the document wasn’t about 1492—or even Columbus. To them, it was about immigration and voting. That threw us for a loop. Then we got it....
