Almost all teachers believe persistent myths about learning, a new survey finds.
More than three-fourths of teachers think that people are either right-brained (creative) or left-brained (analytical), and that those designations affect how they learn. And nearly all teachers endorsed the idea of 鈥渓earning styles"鈥攎eaning that students learn more when their teachers tailor instruction to their individual styles, such as auditory, visual, or kinesthetic.
But research doesn鈥檛 back up these ideas, said Ulrich Boser, a researcher who leads the firm and conducted the survey.
Prior research has found that of the thousands of articles published on learning styles, most didn鈥檛 test the concept in an experimental setting. Just last year, didn鈥檛 correlate to their teachers鈥� perceptions, which researchers said indicated that the concept is 鈥渉it or miss.鈥� And both hemispheres of the brain are involved in almost all cognitive tasks.
鈥淚t鈥檚 really not the fault of teachers鈥攚e have a system that does not give them enough support in terms of what the research says,鈥� said Boser, who is also a senior fellow at the Center for American Progress, a left-leaning think tank.
The survey was conducted online through , which pays participants to complete polls. The results are based on the responses of 203 educators. A large majority of respondents were classroom teachers from across grade levels, while a few dozen were support staff and a handful were administrators.
The survey asked the educators 11 questions related to the science of learning. Respondents answered fewer than half correctly on average.
For example, research says that retrieval practice鈥攁ctively trying to remember information鈥攊s the way to build long-term knowledge. But just 31 percent of respondents said retrieval practice is more effective for learning than re-reading. However, when given a specific classroom scenario, 59 percent of educators correctly endorsed retrieval practice.
And research establishes that 鈥渋nterleaved鈥� practice鈥攐r mixing up different kinds of problems or materials鈥攊s a more effective way of learning than 鈥渂locked鈥� practice, in which learners solve blocks of questions of the same problem type. But when the survey presented a specific classroom scenario with these two concepts, only 20 percent of respondents said interleaved practice is more effective for long-term learning than block learning. When the survey asked respondents about interleaving more generally, 35 percent said it was the more effective strategy.
There were some bright spots in educators鈥� knowledge. For example, about 60 percent of educators correctly responded that three research-supported learning strategies鈥攅laboration, spacing, and metacognition鈥攚ould be more effective than a strategy shown to be ineffective, regardless of how the question was asked.
Most educators correctly chose elaboration鈥攍inking new information to other information鈥攊nstead of repetition; spacing out practice instead of cramming to promote long-term retention; and the metacognitive strategy of self-explanation (thinking out loud) instead of simply memorizing steps.
The survey also asked respondents to list their top three places to learn about new research and evidence in education. Two-thirds of educators listed conferences, 59 percent said professional development, and 53 percent point to their peers.
Boser said schools should provide accurate information on the science of learning through those channels, in an effort to combat these myths. But it should start in teacher preparation, he said.
鈥淢any schools of education don鈥檛 embrace the cognitive sciences,鈥� Boser said.
Yet they have a responsibility to prepare teachers to stay abreast of the current research in the cognitive sciences: 鈥淚t would be weird if large swathes of American doctors believed in bloodletting,鈥� he said.
