Criteria Feedback
- The student sustains a clear and relevant line of argument throughout the essay.
- The student uses appropriate examples from both natural science and history to support their points.
- The student shows awareness that doubt can be productive in some contexts and obstructive in others.
- The student returns to the title in the conclusion and maintains a balanced, qualified judgment.
- Some examples are discussed more broadly than analytically, so the evaluation is not always fully developed.
- A few claims about history would be stronger with more precise evidence and clearer explanation.
- At times the distinction between doubt as a method and doubt as a result could be sharpened.
- The conclusion could be slightly more conceptually precise in explaining how the student's argument answers the title.
