That’s a very valid question. It is obvious to forget or miss out of information if it is coming in loads and lumps. The organisation of data won’t be enough especially in case of learning a whole new language where every letter and word is vital to remember.

What we’ve chosen as an ideal technique to maximise memorisation is spaced repetition.

Spaced repetition is commonly applied in contexts in which a learner must acquire a large number of items and retain them indefinitely in memory. It is, therefore, well suited for the problem of vocabulary acquisition in the course of second language learning, due to the size of the target language’s inventory of open-class words.


By introducing time intervals between study sessions, one can remember more. This is called spaced repetition. Spaced repetition leverages a memory phenomenon called the spacing effect, which describes how our brains learn more effectively when we space out our learning over time.

You can think of learning as being kind of like building a brick wall; if you stack the bricks up too quickly without letting the mortar between each layer solidify, you’re not going to end up with a very good wall. Spacing your learning allows that “mental mortar” time to dry.

Time intervals that have been scientifically proven to help you remember the most information. The question is, what are the optimal time intervals?

Piotr Wozniak spent a ton of time researching this question. Here’s a simplified, nutshell-version of some of his first optimal intervals:

  • First repetition: 1 day
  • Second repetition: 7 days
  • Third repetition: 16 days
  • Fourth repetition: 35 days

Chitrangda Chauhan is a psychology teacher at Jayshree Periwal High School, Jaipur. She has been associated with teaching for more than 3 years now and is also a counsellor. She explains, “A follow up is a must whenever we teach something new to a child because of their distracted attention. For example, if a child learns something from your app, shuts down the app after a while and is by chance offered an ice-cream. The entire attention of the child is now focused on the new temptation which might be more reinforcing for the child. Hence, the parents/guardians should make sure they give the child’s brain a good amount of time to register the content in their sub-conscience after they are done with the day’s lesson.

Following the same technique, Hello English Kids App has been designed to reinforce previously learned things at correct intervals by automatically suggesting daily activities and homework as a comprehensive set of old and new activities.
