WeBWorK is a Perl-based system for delivering individualized homework problems over the web. It was originally developed in 1995 by Profs. Arnold Pizer and Michael Gage at the University of Rochester Department of Mathematics, for use in mathematics instruction. It is now supported by a team of developers from several institutions and is used for a variety of subjects.
WeBWorK enhances the educational process in several ways. By providing students with immediate feedback as to the correctness of their answers, students are encouraged to make multiple attempts until they succeed. By individualizing problems, cheating is discouraged. By providing instructors with real-time statistics, lesson plans can be customized to better serve students.
A library of canned problems is provided, with over 12,000 problems contributed to the National Problem Library (or NPL) at last count. A large collection of macro files which simplify writing new problems is also available. (Use the MathObjects macros provided by Davide Cervone where ever possible to simplify the writing of the problem and to make it easier to maintain.
