Step-by-step explanation:
A rubric is a predetermined set of criteria used to assess an artwork and assign a letter grade. It is used by instructors to evaluate the quality and effectiveness of the artwork based on specific criteria. The rubric typically includes different categories or elements that contribute to the overall assessment, such as composition, technique, creativity, and concept.
Each letter grade is defined by specific criteria within these categories. For example, in the category of technique, an artwork may be assessed based on the use of color, brushwork, and precision. The rubric provides a clear framework for evaluating artworks objectively and consistently.
To decide which set of criteria best fits each individual artwork, the instructor will review the artwork and compare it to the criteria outlined in the rubric. They will determine which criteria align closely with the strengths and weaknesses of the artwork. By doing so, they can assign a letter grade that accurately reflects the quality and achievement of the artwork.
