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.

Claims (9)

1. A method for scoring user responses to a test question, comprising:

receiving a user response wherein the response is a collection of objects with one or more attributes;

binding one or more variables identified in a binding tree based on the collection of objects;

evaluating at least one named assertion associated with an element;

assigning a value to each node of the binding tree based on the named assertion;

storing the named assertion; and

scoring the binding tree based on each value of the nodes, wherein the scoring determines the range of scores.

2. The method of claim 1 , further comprising commencing the evaluation of a scoring tree by starting with a full credit integer score.

3. The method of claim 2 , wherein the evaluation of the scoring tree is stopped when a subtree associated with a score evaluates to true.
