psychologist Hermann EbbinghausHermann Ebbinghaus discovered in 1885 that people forget 80% of the newly learned material with 24 hours.

Who came up with spaced repetition?

The basis for spaced repetition research was laid by Hermann Ebbinghaus, who suggested that information loss over time follows a forgetting curve, but that forgetting could be reset with repetition based on active recall.

What is spacing in psychology?

The spacing effect is the observation that repetitions spaced in time tend to produce stronger memories than repetitions massed closer together in time. Research on the spacing effect dates back to Ebbinghaus (1885) and his book, Memory: A Contribution to Experimental Psychology.

What is Hermann Ebbinghaus known for?

Hermann Ebbinghaus, (born January 24, 1850, Barmen, Rhenish Prussia [Germany]—died February 26, 1909, Halle, Germany), German psychologist who pioneered in the development of experimental methods for the measurement of rote learning and memory.

What did Ebbinghaus discover?

Hermann Ebbinghaus (24 January 1850 – 26 February 1909) was a German psychologist who pioneered the experimental study of memory, and is known for his discovery of the forgetting curve and the spacing effect.

Who invented spaced learning?

A German psychologist and researcher in quantitative memory, Hermann Ebbinghaus, was the first to demonstrate the spacing effect. According to him, one can maximize learning retention by repeating instructions at regular intervals.

When was spaced repetition invented?

Answer. Spaced repetition was invented by Piotr Wozniak in Poland in 1985. It was first implemented in software in 1987, and described in Optimization of learning (1990). It was first published in a peer reviewed journal in 1994 (see: Optimization of repetition spacing in the practice of learning).

Is the spacing effect real?

Applying the spacing effect in the classroom



We may not know why the spacing effect happens, but centuries of research shows it’s real and can help students learn.

What is an example of spacing effect?

For example, studying a vocabulary list for 10 minutes every day for a week may result in permanent memorization of the vocabulary where studying the list for 70 minutes consecutively may only result in short term memorization of the list.

What is the spacing effect AP Psychology?

Spacing effect: The tendency for distributed study to result in better, longer-term retention than other methods.

Is spaced repetition scientifically proven?

Spaced Repetition has been proven by science to help you retain much more information than traditional learning techniques, such as cramming for a test or lengthy classroom sessions.

Does Khan Academy Use spaced repetition?

As you all may be aware, spaced repetition has been shown by cognitive science to be one of the best ways for retaining information over the long term. The beauty of Khan Academy is that one can easily do that on her own volition.

Who was the famous memory researcher that first proposed spacing effects?

Herman Ebbinghaus is known as a pioneer in the field of quantitative memory research, with his most important findings in areas of forgetting and learning curves. Herman Ebbinghaus first detailed the spacing effect in his published book Memory: A Contribution to Experimental Psychology in 1885.

What is spaced repetition algorithm?

Spaced repetition is a technique for efficient memorization which uses repeated review of content following a schedule determined by a spaced repetition algorithm to improve long-term retention. However, current spaced repetition algorithms are simple rule-based heuristics with a few hard-coded parameters.

Why is spaced repetition so effective?

Spaced repetition is simple, but highly effective because it deliberately hacks the way your brain works. It forces learning to be effortful, and like muscles, the brain responds to that stimulus by strengthening the connections between nerve cells.

What is spaced learning method?

Spaced learning is a learning method in which highly condensed learning content is repeated three times, with two 10-minute breaks during which distractor activities such as physical activities are performed by the students.
