Scaffolding for ELs
Scaffolding...when I hear this word, I think of the small trees that were planted in my front yard. Around them, the gardeners placed metal tree stakes as supports. Scaffolds in teaching are like the stakes around the tree.
Interestingly enough, it is suggested that the sooner the stakes are removed, the sooner the plant can develop a strong trunk and root system. And staking a tree that does not need it can do more harm than good. So in essence, though stakes in general seem like a good thing, if implemented incorrectly, they can harm the tree.
