Spaced practice is a feasible and cost-effective way to improve the effectiveness and efficiency of learning, and has tremendous potential to improve educational outcomes.

Perhaps the most important discoveries are those which relate to the appropriate distribution of the periods of study...Acts of revision should be spaced in gradually increasing intervals, roughly intervals of one day, two days, four days, eight days, and so on.

The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it.

From 1880 to 1885, Hermann Ebbinghaus ran a study about the memorisation of nonsense syllables, such as "WID" and "ZOF" by repeatedly testing himself after various time periods and recording the results. He plotted these results on a graph creating what is now known as the "forgetting curve".

Murre and Dros present a successful replication of Ebbinghaus’ classic forgetting curve from 1880 based on the method of savings. The forgetting curve has indeed been replicated and that it is not completely smooth but most probably shows a jump upwards starting at the 24 hour data point.

The speed of forgetting depends on a number of factors such as the difficulty of the learned material (e.g. how meaningful it is), its representation and physiological factors such as stress and sleep. Furthermore higher original learning also reduces forgetting. The rate differs little between individuals.

Spitzer tested 1939 the effects of a type of spaced repetition with over 3600 students who were learning science facts and showed that spaced repetition was effective.

Memory formation becomes more effective with longer inter-stimulus intervals between training sessions because of decreasing temporal overlap between successive, short-lived learning traces.

I hardly ever missed school, and I always got my work in on time. I was a good student and always got top grades.

Rule one: Write about settings you're familiar with.

I love being a woman and I was not one of these women who rose through professional life by wearing men's clothes or looking masculine. I loved wearing bright colors and being who I am.

Movie directors who have filmed F. Scott Fitzgerald's 'The Great Gatsby' believe it's a big book looming inside a small one, and they aren't altogether wrong.

As educators and policy makers, it is important to demonstrate for parents the connection between high levels of student participation in assessment and system accountability - ensuring the success of every student.

Take care of your body and your body will take care of you.

I don't listen to people who say my dreams are impossible; I just work to prove them wrong.

If age someday grounds my feet and wilts my port de bras, what vestige of the old life will be left? The signs that I was a dancer will gradually fade like stripes on a beach towel. Even my knowledge of the art form, reaped in sweat over decades, could be lost over time.

I grew up being taught, 'Do unto others as they would do unto you.' I would get scolded for not being polite.

I didn't come to Washington to fight against my Republican colleagues, or even against my colleagues on the other side of the aisle. I came to Washington to fight for the values that make our country unique - for the economic freedom that gives life to the American Dream.

And Louis Freeh was a completely dysfunctional FBI Director, who was actually waging his own private war against the Clinton Administration.

I'm not a food critic, and I'm not really an authority to write anything on food.

My first workshop was in Rome, and that was the start of House of Waris. In a little magical atelier, a goldsmith, his apprentice, his stone setter - and that was where it began.

Do I race motorcycles? I do. I use the word 'race' because, I admit, what I do on a motocross bike is different than riding a Harley down the street.

If I had my way, I wouldn't do annual reviews, if I felt that everybody would be more honest about positive and negative feedback along the way. I think the annual review process is so antiquated.

Family preparedness has been a long-established welfare principle.

I like clothes that are easy to wear. I like to be comfortable and confident. When people have an inner sense of confidence, they're more beautiful.

Climbing the economic ladder has been very hard for me I still feel a great deal of guilt towards those I left behind.

I've always saved. I believe in keeping money back for a rainy day and living within my means. I don't buy expensive clothes; I have a 10-year-old car I'm hoping to replace when a big job comes in. I suppose when we do go on family holidays, I am quite happy to spend when we are there.

I know, because I tried all sorts of ways of being in character, and the best way is to be totally straight.

Activists can get very preachy about things. It's more about understanding people's own experiences and tapping into them.

In philosophy, it is not the attainment of the goal that matters, it is the things that are met with by the way.

We immerse ourselves in escapist mass entertainment, such as 'reality T.V.' programs. We support fanatical politicians and preachers. Our politicians, in turn, support dictators and tyrants in other countries, all in the name of 'security' and 'stability'. And we arm ourselves to the teeth, and pray to God to be saved.

At WhatsApp, our engineers spend all their time fixing bugs, adding new features and ironing out all the little intricacies in our task of bringing rich, affordable, reliable messaging to every phone in the world. That's our product, and that's our passion. Your data isn't even in the picture. We are simply not interested in any of it.
