Low-stakes assignments are usually done overnight with no revision. Their purpose is to help students engage with and learn course content and/or to practice skills needed for higher-stakes assignments. They are not supposed to be examples of beautifully finished writing.
Individual assignments are worth a very small percentage of the course grade, though taken together, a series of low-stakes writings may comprise a larger percentage of the total course grade.
Examples of low-stakes assignment forms: note cards with questions or brief summaries/analyses, maps/visuals, journals, letters (including the famous “letter to your grandma”), dialogues, emails, entrance and exit slips.
