In education circles, testing has become the villain of the day. Kids declare exams to be a waste of time while educators argue that the anxiety around tests produces a “toxic environment.” Families loathe exams, too, as I learned when doing some research on assessments, with parents often viewing tests as either a distraction from more valuable activities or as “testing for testing’s sake.”
But when it comes to learning, it turns out, the best research shows that exams serve learning rather than harm it, and most schools and universities actually should be doing more testing, not less of it. A large and growing body of studies indicates that assessments serve students learn. More — and better — testing programs can also serve teachers teach.
Cutting against the grain of total the negative chatter approximately tests, some cognitive psychologists, including Yana Weinstein at University of Massachusetts Lowell, own declared themselves to be “champions” of testing.
The catch is that the tests own to be the right kinds of tests. The exams that spark learning typically tend to own lower stakes, they own more open-ended questions, and they are given often enough to supply clear feedback to teachers and students. But whether they’re well designed, tests own been proven to serve students achieve mastery of the subject fabric — not just evaluate progress.
To be certain, there are first-rate reasons that tests own a tarnished brand. For years, assessment programs own been weak. Many schools and universities own relied heavily on multiple-choice exams, which often finish diminutive to degree (or instill) richer forms of understanding. Up until a few years ago, a few states, including North Carolina, gave English exams that didn’t include any writing tasks, which is a bit like administering a driving test without the student ever driving a car.
For many years, testing programs also didn’t provide enough feedback. For instance, final exams often serve to determine a student’s grade. But that kind of assessment happens too infrequently — and, nearly by definition, too late — to supply useful information. The high-stakes nature of such tests is also total but guaranteed to spark unproductive anxiety.
The exams that some students own to pass to collect a high school diploma are the epitome of a high-stakes test. Not surprisingly, these exams can cause cheating and stress. Many of these formal, high-stakes exams also consume weeks — whether not months — to grade. While the exams might construct a high school diploma appear more meaningful to colleges and employers, the results typically approach far too late to shape what happens in specific classrooms in specific years.
Quizzes provide instant feedback, allowing teachers to fine-tune their lessons
This total stands in stark contrast to the kinds of tests most firmly backed by the evidence. These research-supported exams, of various kinds, finish a few different things. First, they can provide frequent checks on student understanding. By using them, educators can fine-tune their lessons to match the learning pace of the students in a classroom.
I saw an instructor consume this sort of quiz-based approach to teaching in a large physics lesson, course at the University of Maryland College Park. It was the first day after spring crash, and the professor, Ben Dreyfus, gave a diminutive quiz approximately electrical charges. The students responded using hand-held “clickers.” Many students had forgotten the fabric Dreyfus asked them approximately, and on a few questions, half the lesson, course gave the wrong response.
So Dreyfus spent the rest of the lesson, course time reviewing the fabric, to ensure that they’d absorbed it before moving on to unusual fabric that built on that knowledge.
A recent academic article on the exercise of clicker-based quizzes in large lectures drives domestic just how useful such temperature-taking can be. One biology instructor quoted in it recalled being amazed that while 90 percent of students recalled a certain rule in genetics, only 48 percent could apply it accurately:
This was a moment of revelation. … for the first time in over 20 years of lecturing I knew… that over half the lesson, course didn’t ‘collect it’…. Because I had already explained the phenomenon as clearly as I could, I simply asked the students to debate briefly with their neighbors and see who could convince whom approximately which reply was right. The lesson, course erupted into lively conversation. After a few minutes, I asked for a revote, and now over 90 percent gave the right reply.
How tests teach: the “retrieval practice effect”
Even more exciting, whether counterintuitive, low-stakes quizzes and exams finish not just test mastery, they serve create it. When we’re quizzed, the act of attempting to express what we know approximately a subject helps to solidify our understanding of the subject at hand. Psychologists call this mechanism the “retrieval practice effect,” or, more simply, the “testing effect.” (Students can exercise a version of this technique by quizzing themselves when studying for bigger tests.)
Researchers Jeffrey Karpicke and Janell Blunt, of Purdue University, own shown that quizzing promotes conceptual knowledge more than some other approaches once thought to be promising — like concept mapping, which involves summarizing what you know by graphical means, on paper or a whiteboard, and connecting related ideas with lines and arrows. On its own, it appears, quizzing helps students systematize their ideas and create a rich “structure” of knowledge.
These insights apply to lengthier tests, too — whether in math or English or social studies. As Logan Fiorella of the University of Georgia, and Richard Mayer of the University of California Santa Barbara argue in their book Learning as a Generative Activity, “students will learn more deeply whether they are able to effectively select main ideas, organize them, and then restate them in their own words.”
In sum, testing “shouldn’t be a white-knuckle finale to a semester’s work,” writes the University of Washington psychologist Henry L. Roediger III, “but the means by which students progress from the start of a semester to its finish, locking in learning along the way.”
Still skeptical approximately the power of testing in learning? Consider a paper released earlier this year. The authors evaluated more than 250 experiments with more than 10,000 participants, in which students had prepared for exams by either rereading fabric they’d been exposed to — a classic approach — or being quizzed approximately it. The researchers found that quizzing sparked far better outcomes than rereading. They concluded: “An overwhelming amount of evidence reviewed in this meta-analysis suggests that [quizzing] increases achievement.”
whether you are out of school, you can still construct exercise of these insights. Whenever you’re trying to grasp a unusual subject, experts recommend that you query yourself a lot of “why” questions. Yes, the Fed tends to raise interest rates when inflation rises — but why?
There’s been progress on the ground: a shift from despicable tests to research-backed exams
In recent years, America’s schools own taken some valuable steps forward when it comes to tests. In K-12 schools, the exams associated with the unusual Common Core standards are better than preceding ones, including a lot more open-ended and essay items.
Policymakers at the state and federal level own also been lowering the stakes on exams. Fewer states exercise a single exam to determine whether a student should collect a diploma, for instance. As the result of a unusual federal education law, states are taking a broader approach to evaluating schools, moving beyond the results of a single test-score to assess school performance.
increasingly educators are using “exit slips,” a type of conclude-of-the lesson, course quiz to test student knowledge — the K-12 equivalent of those college clicker quizzes.
No doubt, a lot of despicable testing still goes on in high-school and college classrooms, and even well-constructed, research-based tests are never going to inspire admire letters. But in the conclude, the proof is in the outcomes, and students who experience more regular quizzing conclude up posting higher grades on their final exams.
Some students own approach to this realization on their own. On the day that I visited Ben Dreyfus’s physics classrooms at the University of Maryland, I sat next to a junior named Brandon Fish. As he pressed the buttons to reply Dreyfus’s questions, he was sometimes surprised by what he remembered, or had forgotten. It could be distressing to discover holes in his knowledge, Fish said, but “it’s helpful to know what you don’t know.”
Near the conclude of our interview, Fish said something that I thought that I’d never hear from a college student, particularly from a generation that has supposedly been tested to death. “I like the quizzes,” he said.
