The biggest contributor to the length of a student's homework is task switching.

When a student chooses to check their text, respond and then possibly take an extended dive into social media, they lose a percentage of the learning that has already happened. As a result, when they return to the AP essay or honors geometry proof, they need to retrace their learning in order to catch up to where they were. This jump, between homework and social media, is actually extending the time a student spends on an assignment.

it turns out that the one thing present in every successful person is one consistent trait. It’s not a person’s education or lack of it, or their IQ, their upbringing, their financial abundance or lack, their test scores, their birth order or their gender. It’s one odd, rarely mentioned quality: Grit.

But grit is more than just an attitude. It’s about the actions we take when faced with doubt and obstacles. In 2006, Drs. Angela Duckworth and Martin Seligman discovered that the correlation between self-discipline and achievement was twice as large as the correlation between IQ and achievement.

A clear goal Determination despite others’ doubts Self-confidence about figuring things out Humility about knowing it doesn’t come easy Persistence despite fear Patience to handle the small obstacles that obscure the path A code of ethics to live by Flexibility in the face of roadblocks A capacity for human connection and collaboration A recognition that accepting help does not equate to weakness A focus and appreciation of each step in the journey An appreciation of other people’s grit A loyalty that never sacrifices connections along the way An inner strength that helped propel them to their goal

Mazur believes the purpose of education is changing. It used to be about mastering a certain amount of knowledge. But knowledge is growing and changing at such a rapid rate that it's impossible to learn it all. The key now is to find and use information, not remember and repeat it. And Mazur says the goal of educators should be to help students develop the skills to understand all the new information that will be coming at them throughout their lives. In other words, the purpose of education now should be to learn how to learn.
