Quote: R.B. Sipe: “While literacy is a complex topic in which individuals ponder questions, seek out information to find answers, and craft a meaningful essay or other kind of writing, including creating a final draft, writing tests are typically more like first-draft writing using none of the tools students learn. In addition, these tests measure discrete items, like semicolons, whereas many aspects of literacy are integrated and interrelated.”
