What WeBWorK is
WeBWorK is a free, open-source online assessment and homework system for math and science courses. It delivers individualized problems over the web, gives students immediate feedback on answer correctness, and allows multiple attempts. Instructors can review real-time statistics to adjust lesson plans. Its Open Problem Library contains more than 35,000 shared problems across mathematics and other STEM subjects. The problem-authoring interface works with Perl and accepts commands from R. WeBWorK supports LTI 1.1 and 1.3 connections with learning management systems including Moodle, Canvas, Brightspace, and Blackboard. Authentication options include LTI, SAML2, or WeBWorK-managed accounts. Hosting can run on an institution's own server, use a free Runestone-hosted course, or be arranged through Rationarium; hosting options and prices vary. Institutional administrators may be responsible for installation and updates. The project points users to forums and Slack for questions. Its SOAP handler is disabled by default; a forum post describes it as unmaintained and potentially vulnerable if enabled.
