Question: How do raters of compositions respond to mistakes in grammar?
Answer: “Respondents assigned more importance to overall quality, organization and development than to the conventions of edited American English.” C Ehlen, 1983, 211.
Comment: Composition and grammar are two different focuses in writing. The one is evaluated for organization and development. The other is focused on sentence structure. Unless you are focused specifically on issues of grammar, you will note the overall organization and development in a first impression. RayS.
