Abstract
We describe Oliver, the Online inference and verification system for
propositional logic. It provides a web-based interface for teaching
propositional logic proofs, and accepts any valid direct proof. Oliver
provides instant feedback to students as to whether each step is
correct or not, encourages experimentation by students and is
integrated within the WeBWorK system for online grading and
support. Oliver randomizes problems for students to reduce plagiarism
and cheating. It has been successfully used to teach propositional
logic to several thousand students at SUNY Stony Brook, and is very
popular among students and faculty.
