This one is a powerful tip from a friend: foreshadow.
The idea is really simple, before you introduce something new to the children, you give them passive or receptive exposure to it.
One of the examples my friend gave me was that, before he’d give the demo class for the language centre, he’d play some of the songs (sometimes more than once) that the children would be exposed to during the demo. When it comes time to learn the song during the demo with their parents, they’d already have heard it twice before. So, they have some familiarity with it, already.
You can do the same thing with classes you teach. For example, in the week before you introduce new vocabulary, you can play songs or videos at the break time (or before or after class) that expose the children to the new vocabulary.
Foreshadowing is a powerful way to support your student’s learning.
