OWLv2 is an all-in-one online teaching solution for Chemistry instructors that delivers an eTextbook, multimedia learning activities, auto-graded assessments, and analytics through an easy-to-use platform. It supports you whether you teach synchronous or asynchronous courses and whether you teach in-person, hybrid, or fully online. You can integrate it into your Learning Management System with automatic grade return. OWLv2 elevates thinking through Mastery Learning, empowering students to work at their own pace to understand each concept. It does this better than other Chemistry products through algorithmic question randomization, high-quality question authoring, instant feedback, and powerful analytics. The randomization of three factors: chemical, numerical, and contextual, creates unique question variants, ensuring that no two students get the same question, and neither does a single student on subsequent attempts.
