Carol Dweck's TED Talk - The power of believing that you can improve

Carol Dweck researches “growth mindset” — the idea that we can grow our brain's capacity to learn and to solve problems. In this talk, she describes two ways to think about a problem that’s slightly too hard for you to solve. Are you not smart enough to solve it … or have you just not solved it yet? A great introduction to this influential field.

Students learn better when they think they're going to have to teach the material




Researchers say they've uncovered a simple technique that improves students' memory for passages of text. All that's required is to tell the students that they're going to have to teach the material to someone else.

Fifty-six undergrads were split into two groups. One group were told that they had 10 minutes to study a 1500-word passage about fictional depictions of The Charge of The Light Brigade, and that they would be tested on it afterwards. The other group were similarly given 10 minutes to study the text, but they were told that afterwards they would have to teach the content to another student. Neither group was allowed to take notes.

In fact, 25 minutes after the study period was over, both groups were tested on the passage. Specifically they had to recall as much information as possible from the article, and then they faced specific questions about the content. The students who thought they were going to teach the material recalled more facts from the text, and they did so more quickly. They showed a specific advantage for the main points in the text, and their recall was also better organised, tending to reflect the structure of the original text. 

A second study was similar but this time two groups of students studied an article about neurobiology and the test that followed took the form of "fill in the blank" questions based on verbatim quotes from the article. This time the students who thought they were going to have to teach the article showed a slight advantage for recalling the main points, although they didn't recall more information overall.

John Nestojko and his colleagues acknowledge that more research is needed to confirm and expand on these results (especially given the more equivocal second study), but they said their findings hint at a simple strategy for improving students' learning. They think that cultivating in learners the expectation of having to teach the material leads them to adopt strategies "such as organising and weighing the importance of different concepts in the to-be-taught material, focusing on main points, and thinking about how information fits together" that are known to boost memory performance.

In a school situation it probably wouldn't be practical for every student to go through the process of teaching learned material, but the expectation of having to teach the material could easily be fostered by announcing that one or more randomly chosen students will play the teaching role. "We hope the present findings encourage future researchers to discover other such potentially easy-to-implement ways of leading students to adopt more effective learning strategies," the researchers said.

Why teens should have their music and sports lessons in the evening?


While you sleep your brain learns. Research with rats has shown how they rehearse maze-routes in their brains whilst they're dozing. And human research has demonstrated that learned material is better recalled after a sound sleep as opposed to a disturbed night. But what hasn't been looked at before now is the optimum time to leave between learning and sleeping.

A team led by Johannes Holz has done just that, finding that "procedural learning" (practice at the kind of skill that you do, rather than talk about) is more effective right before sleep. Learning factual material, by contrast, (dependent on "declarative memory"), was found to be more effective when done in the afternoon, seven and a half hours before sleep, although the evidence for this was less convincing and should be treated with caution.

The researchers recruited 50 teenage girls (aged 16-17) to learn a series of word pairs and a finger-tapping task, either at 3pm in the afternoon or 9pm at night. The performance level of the afternoon and night groups was equivalent at the end of these initial learning tasks.

With the tapping task, it was the girls who learned right before sleep who showed the greatest gains in performance when they were re-tested after 24 hours and again 7 days later. Holz and his colleagues can't be sure why procedural learning is more effective just before sleep, but they think it probably has to do with the effect of sleep on protein synthesis and gene expression.

In contrast to the tapping task, performance on the word pairs after 24 hours was better in the afternoon-learning group. At the 7 day word-pairs test there was no difference in afternoon or evening learners. The fact that declarative learning was more effective in the afternoon suggests that this type of hippocampus-dependent memory has a different time course from procedural learning.

The findings, though preliminary, have obvious practical implications. "We propose that declarative memories, such as vocabulary words, should be studied in the afternoon and motor skills, like playing soccer or piano, should be trained in the late evening," the researchers said. "Most parents among us would have preferred the opposite results."
