Abstract

This paper describes the methods and results of an effort to alleviate work loads associated with large class sizes in the Computer Science Department at Southeastern Louisiana University. One of the most laborious tasks for a computer science instructor is to grade exams from a large class. A typical quiz in Data Structures is 5 to 7 pages, with several of those having questions in which the student writes a pseudo code answer. With a class size of 40, the instructor could be grading anywhere from 120 to 200 pages of pseudo code for one quiz. This paper describes a first attempt to automatically grade in a syntax independent manner the pseudo code using a sliding correlation based method. The algorithm is described along with a test in which the algorithm was fed student's answers. The algorithms results compare favorably with the graders.
