SYSTEM AND METHOD FOR USING OPTICAL CHARACTER RECOGNITION TO EVALUATE STUDENT WORKSHEETS

机译:使用光学字符识别来评估学生作业的系统和方法

摘要

A system and method for evaluating worksheets are provided. The method includes accessing by a processor a digitally stored image of a worksheet that was administered to a student, wherein the worksheet includes the presentation of at least one problem for the student to respond to and each problem presentation includes an answer region that the student manually, mechanically, or electronically marked with an answer to the problem using a variety of alphanumeric characters. The method further includes generating expected answer data that provides an expected answer for each answer region; locating each answer region in the image; extracting from each located answer region the student's marks; processing the student's marks extracted from each answer region with character recognition processing; and storing the processed marks as student answer data. The student answer data is evaluated by comparing the student answer data with the expected answer data and generating corresponding evaluation data.
