  • Patent number: 8170466
    Abstract: A system and method for automated assessment of constrained constructed responses provides for automatic, e.g., programmatic, assessing of a test subject response to a constrained constructed response item or question. In one embodiment, paper test materials with test subject markings thereon are converted to electronic form. Test subject markings are further isolated, for example, by registration, sizing and removal of markings other than a graphic response. The subject markings are further compared with a baseline response, correctness deviation criteria and incorrectness deviation criteria (e.g., correctness, incorrectness, substantial correctness, substantial incorrectness, and so on) from which one or more of a score, further learning or other assessment results may be determined. Cluster analysis or other post-evaluation or post-assessment processing may also be conducted, or re-evaluation or re-assessment may also be conducted.

  • Patent number: 8086166
    Abstract: The methodology of the present invention is implemented by a system which defines concepts about which a respondent is required to demonstrate knowledge of a relationship. The concepts are represented by respondent-manipulable devices that are uniquely associated with the concepts, and the respondent is able to manipulate attributes of the devices to create an arrangement of the devices representative of the respondent's understanding of the relationship of the concepts with which the devices are associated. The attributes of the manipulated devices are recorded and converted into a response pattern based on the cognitive relationships of the devices as manipulated by the respondent. One or more predefined rubric patterns are associated with the constructed response item and define possible cognitive patterns of the concepts as represented by the devices. The response pattern is compared to the rubric pattern to identify matches between the response pattern and the rubric pattern.

  • Patent number: 7911660
    Abstract: Methods and apparatus are disclosed for locating an area of interest within a digital image of a form captured by an imaging scanner. Specific examples include methods and apparatus for optical mark reading with a digital imaging scanner. In many of the methods, an image of a response form is captured by a scanner, and “target” areas for possible responses are located within the image based upon an expected location being adjusted as necessary for certain error-inducing defects in the forms or scanning process. Also disclosed are steps to normalize the darkness values of pixels captured from an optically scanned form.

  • Patent number: 7606421
    Abstract: In a method and system to extract data from handwritten information when the information is captured as sequences of strokes, vectors, or marks, temporal data is stored within the color or gray-scale encoding of pixel values within a bitmapped image. A bitmapped image is used to create a derived image suitable for data extraction and a method of analyzing the image, including the encoded temporal data, to yield an adjusted image that better reflects the intent of the person who created the handwriting. While the primary application of the invention is in processing handwritten responses to assessment items, the system and method can be advantageously used to extract data from or to improve the presentation of information from an electronic representation of temporal human marks in many applications. Additionally, the system and method can be advantageously used to store and process other types of data within a bitmapped image.

  • Patent number: 7417774
    Abstract: Methods and apparatus are disclosed for identifying intended response marks in an optically scanned image of a response sheet having key marks and response targets printed in the same color. Pixel darkness values assigned by a digital imaging scanner are used to locate key marks and response targets and to identify response marks. Areas of the sheet may be selectively filtered to mask the response targets. Alternatively, a color imaging scanner may be used to produce a set of color values, such as RBG values, for each pixel. Software can act as a virtual filter by using the RBG values to detect or to mask a color in the image.
