Abstract
The invention generally concerns a method of generating a real number score for a response, such as a written essay response. The method comprises providing a scoring model having one or more concepts; determining for each concept a probability that the concept is present in the response; creating a scoring rule or scoring rule function; determining an expected value function for the scoring rule; and generating a real number score for the response based on the scoring rule, the expected value function, and the probabilities that the concepts are present in the response (or a combination thereof). The real number score for the response may then be displayed or output, for instance, where the method is implemented as a computer system or application. Concept-based scoring provides improved scoring accuracy and individualized feedback for students and reports for teachers and parents.
