According to this hypothesis, teachers should be aware that certain structures of a language are easier to acquire than others and therefore language structures should be taught in an order that is conducive to learning. Teachers should start by introducing language concepts that are relatively easy for learners to acquire and then use scaffolding to introduce more difficult concepts.
Scaffolding is the teaching technique that involves providing students with the supports needed to complete a task or facilitate their learning of new concepts. Some students need more scaffolding than others, but those who don’t need the supports do not need to use them. As the students develop and their abilities in a particular area improve, the supports related to that area can be gradually removed. Tasks and activities can be broken down into achievable chunks for the students so they are able to gain confidence in their abilities without feeling too much stress or anxiety.
