In my next post, I will go into more detail about NPR’s approach to content modularity and why our approach is more than just data normalization.

Every interview subject conducted some sort of a literature review as part of any research project

Every researcher described some strategies for keeping up with new developments in their area of expertise, all of which involved some scanning of new publications and some personal contact with individuals exploring the same territory.

For most, presenting research at conferences was a common part of bringing their research to completion. For all, writing up results for publication was an important final step, and they seemed acutely aware of the pecking order for publication venues in their field.

(In contrast, undergraduates mostly encounter articles within databases, called up by key words, not as artifacts within a particular journal which carries clout.)

One thing the students all gained through these interviews was an appreciation that research is not a matter of finding answers in other people’s publications. Every scholar interviewed described how they had asked a question that nobody had asked before, a question they couldn’t answer themselves until they had completed the research. It struck me that so much of what undergraduates experience as “research” is very nearly the opposite, a process of uncovering answers others have already arrived at.

I’m also thinking about what these interviews said collectively about how real research is conducted. It makes me a little crazy when students abandon a truly interesting question because they can’t find sources to quote that provide the answer, or when they change their topic based on what they can find easily. Or (shudder) when they say they've written their paper, but need help finding five sources to cite. Clearly, they are not learning how to do research; they aren't even learning what research is.  What I would really, really like is to figure out how to give every student the experience of not worrying so much about getting the right answers, but learning how to ask a really good question. The kind they won't find answered in the library.

He proposes what he calls the “page a year” solution: in first grade, a one-page paper using one source; by fifth grade, five pages and five sources.

The National Survey of Student Engagement found that in 2011, 82 percent of first-year college students and more than half of seniors weren’t asked to do a single paper of 20 pages or more, while the bulk of writing assignments were for papers of one to five pages.

“Writing term papers is a dying art, but those who do write them have a dramatic leg up in terms of critical thinking, argumentation and the sort of expression required not only in college, but in the job market,” says Douglas B. Reeves, a columnist for the American School Board Journal and founder of the Leadership and Learning Center, the school-consulting division of Houghton Mifflin Harcourt. “It doesn’t mean there aren’t interesting blogs. But nobody would conflate interesting writing with premise, evidence, argument and conclusion.”

The debate about academic writing has given rise to new terminology: “old literacy” refers to more traditional forms of discourse and training; “new literacy” stretches from the blog and tweet to multimedia presentation with PowerPoint and audio essay.

Reviewing the test of conceptual understanding, Mazur twice tried to explain one of its questions to the class, but the students remained obstinately confused. “Then I did something I had never done in my teaching career,” he recalls. “I said, ‘Why don’t you discuss it with each other?’” Immediately, the lecture hall was abuzz as 150 students started talking to each other in one-on-one conversations about the puzzling question. “It was complete chaos,” says Mazur. “But within three minutes, they had figured it out. That was very surprising to me—I had just spent 10 minutes trying to explain this. But the class said, ‘OK, We’ve got it, let’s move on.’

Interactive pedagogy, for example, turns passive, note-taking students into active, de facto teachers who explain their ideas to each other and contend for their points of view.

Interactive learning triples students’ gains in knowledge as measured by the kinds of conceptual tests that had once deflated Mazur’s spirits, and by many other assessments as well.

Peer-instructed students who’ve actively argued for and explained their understanding of scientific concepts hold onto their knowledge longer.

This innovative style of learning grew into “peer instruction” or “interactive learning,”

“Now, think of how you became good at it,” he says next. Audience members, supplied with wireless clickers, can choose from several alternatives: trial and error, apprenticeship, lectures, family and friends, practicing. Data from thousands of subjects make “two things stand out,” Mazur says. “The first is that there is a huge spike at practicing—around 60 percent of the people select ‘practicing.’” The other thing is that for many audiences, which often number in the hundreds, “there is absolutely zero percent for lectures. Nobody cites lectures.”

The active-learning approach challenges lecturers to re-evaluate what they can accomplish during class that offers the greatest value for students. Mazur cites a quip to the effect that lectures are a way of transferring the instructor’s lecture notes to students’ notebooks without passing through the brains of either.

So I began to ask my students to read my lecture notes before class, and then tell me what questions they have [ordinarily, using the course’s website], and when we meet, we discuss those questions.”

Students find a neighbor with a different answer and make a case for their own response. Each tries to convince the other. During the ensuing chaos, Mazur circulates through the room, eavesdropping on the conversations. He listens especially to incorrect reasoning, so “I can re-sensitize myself to the difficulties beginning learners face.” After two or three minutes, the students vote again, and typically the percentage of correct answers dramatically improves. Then the cycle repeats.

‘We’ve never done a problem of this kind.’ I tell them, ‘If you had done a problem of this kind, then by definition, this would not be a problem.’ We have to train people to tackle situations they have not encountered before.

“It’s not easy. You get a lot of student resistance,” he continues. “You should see some of the vitriolic e-mails I get. The generic complaint is that they have to do all the learning themselves. Rather than lecturing, I’m making them prepare themselves for class—and in class, rather than telling them things, I’m asking them questions. They’d much rather sit there and listen and take notes.

In addition to student resistance, there is architectural resistance. “Most classrooms—more like 99.9 percent—on campus are auditoriums,”
