Part of apprenticing students into disciplinary thinking is supporting their understanding and use of language. The Useful Language tool offers students models for their own writing. A key feature of the Useful Language tool is that language choices are offered to support writing each component of an argument, helping students understand that there is more than one way to make a claim, present evidence and reasoning, and respond to counterarguments. The Useful Language tool reminds students about and supports them in presenting the important thinking moves that make an argument strong.
