The deepest learning experiences come from extended intermitted interaction with the subject material. ChemVantage provides free quizzes, homework assignments and practice exams that keep students engaged by allowing multiple submissions until students succeed. Randomized quizzes are designed to be completed before the lecture, to promote discussion. Challenging homework problems focus on application skills. Parameterized questions ensure that students cannot share answers, but can teach each other the algorithms for solving the problems.

You may obtain a free set of LTI credentials at https://www.chemvantage.org/lti/registration.

Research conducted at a flagship research university shows that students who earn at least 50% of the points on ChemVantage assignments pass General Chemistry (C- or better) with 97% probability.

We do not share any user information with anyone except instructors and the user's LMS through a secure LTI interface. Personally identifiable information - Except for LMS administrators and people who contact ChemVantage directly via email (e.g., to establish an account), Chemvantage does not store any user PII. No names, no passwords, no addresses, no phone numbers. Because ChemVantage is a free service, we do not process, collect or store any user credit card or financial information whatsoever.

We do not collect information about IP addresses, locations, or browser information of our users. We do not display any advertisements or enter into any service agreements with third party advertisers. User IDs - During each user's session, ChemVantage issues a cryptographically signed token containing an opaque user ID to ensure both privacy and security. For LTI users, this ID is provided by the learning management system (LMS). LTI is a secure messaging and communications standard developed by the IMS Global Learning Consortium. LTI connects students and instructors with educational service providers. ChemVantage is a certified LTI provider.

We also use timestamps to automatically delete LTI accounts after one year of inactivity.
