  • Patent number: 10643489
    Abstract: A system, method, and related techniques are disclosed for scoring user responses to constructed response test items. The system includes a scoring engine for receiving a user response to a test question and evaluating the response against a scoring rubric. The scoring rubric may include a binding stage, an assertion stage, and a scoring stage. Furthermore, the system includes a database for referencing elements used by the scoring engine which may comprise objects, object sets, attributes of objects, and transformations of any elements.
    Type: Grant

  • Patent number: 8270725
    Abstract: A method for creating a page template corresponding to a form for use in a mark recognition system includes identifying at least one path of traversal across a form, detecting edge transitions along each such path, and creating page template using the detected edge transitions.

  • Publication number: 20120150328
    Abstract: A method for scoring constructed responses is provided. The method includes: establishing a question that requires a constructed response; determining at least one attribute parameter that defines the format of the constructed response; binding at least one variable to the at least one attribute parameter; defining at least one assertion rule, each setting forth a condition that the at least one variable will either satisfy or not satisfy; and creating a scoring system that includes at least full scoring credit if all of the at least one assertion rule is satisfied and partial scoring credit if some but not all of the at least one assertion rule is met; wherein when the question is presented and a constructed response received, the corresponding at least one variable is compared against the at least one assertion rule to identify which assertion rule is satisfied or not, and a score is provided based on the number and/or combination of satisfied at least one assertion rule.
