Bite-sized Learning and Spaced Repetition

Bite-sized Learning and Spaced Repetition

Just like leading a healthy lifestyle, word learning is a matter of habit formation. The key to success is consistency and perseverance, or learning ‘little and often’.

Bite-sized learning

Learning a few words often is more effective than learning more words less frequently. Various research studies have found that learning a few words thoroughly and frequently has been shown to work better than teaching many units in one go, once in a while.[1],[2] 

  • Specifically, the little and often method was found to be 90% more effective than cramming many words in one go.[3]
  • Moreover, children who learned words in this way were found to remember 35% more words than those who were taught the same vocabulary in a crammed manner.[4] 

A possible explanation for this result is that words learned in this way are more likely to be stored in the long-term memory. 

Spaced repetition

According to research, a child needs several encounters with a word in order to learn it - a minimum of six encounters is often recommended, but sometimes it could take up to 12 repetitions for the word to really stick. This will depend on the amount of information relevant to the new word that the child is exposed to.
  • Repeated exposures are most effective when they appear over an extended period of time.[5]

Our Epic Word Adventure algorithm ensures that children encounter each word enough times and with the right amount of time between each encounter in order to maximise learning effectiveness.

    Mrs Wordsmith products are designed to help you make word learning a part of your daily routine. Whether it’s one word at breakfast every day or a couple on the way home from school, if it’s fun, kids will want to keep it up. Just remember, little and often is the key to success!
