Answer:
In essay grading, Purpose/Structure and Development are two categories that are assessed by examiners. The difference between a four and three in these categories is that a four essay has a clear and logical structure, with a thesis that is fully developed and supported by evidence and analysis. The essay also has effective transitions between paragraphs and ideas. On the other hand, a three essay may have a somewhat clear structure, but the thesis may be underdeveloped or not fully supported by evidence.
The difference between a two and one in these categories is more significant. A two essay may have an unclear or illogical structure, with a thesis that is weak or missing altogether. The essay may have little to no supporting evidence or analysis, and transitions may be ineffective. In contrast, a one essay may lack any discernible structure or organization, with a thesis that is absent or completely unsupported. The essay may also have little or no evidence or analysis, and transitions may be absent or ineffective.
Therefore, it is important for students to understand the importance of Purpose/Structure and Development in essay writing and to strive for a clear and logical structure with a well-developed thesis supported by evidence and analysis. This will help them to achieve a higher grade in their essays.
