In This Documentary
For decades psychologists cautioned against raising children bilingual. They warned parents and teachers that learning a second language as a child was bad for brain development. But recent studies have found exactly the opposite.
If there's consensus on anything in education, it's this: Tests are awful. But maybe we've been thinking about tests all wrong. Research shows that tests can actually be powerful tools for learning -- but only if teachers use them right.
Humans obviously learn a lot of things through trial-and-error. A level of "desirable difficulty" built into a learning and exam process appears to boost the overall retention of new skills or knowledge.
