Take it into a passage
Testing a proposal
A student editorial asserted that moving all homework online would make school more accessible. Its premise was that every student had a reliable device and internet connection at home. Before accepting that claim, Noor decided to scrutinize it. A school survey showed that some families shared one device, and several students relied on library internet. These findings did not refute every benefit of online work, but they gave a counterargument to making it the only option. Noor qualified the proposal: teachers could offer digital materials while keeping printed copies available. She also asked for a trial period to evaluate the results. Her conclusion remained tentative because the survey did not describe every family's circumstances.
Explain your thinking
How does Noor qualify the original proposal, and why is that different from rejecting all digital homework?
See a sample response
She changes an all-digital proposal into a choice between digital and printed materials. This addresses uneven access while preserving potential benefits of digital work. She limits the proposal instead of claiming digital homework has no value.
Write with the words
Write 5–7 sentences about whether students should choose some of their own reading assignments. State a premise, consider a counterargument, and qualify your conclusion. Use those three terms accurately, and name evidence you would need to evaluate the idea.
