Book excerpt: Active learning occurs when a learning task can be related in a non-arbitrary manner to what the learner already knows and when there is a personal recognition of the links between concepts. The most important element of active learning is not so much in how information is presented, but how new information is integrated into an existing knowledge base. In order to successfully implement active learning into higher education, its effect on student engagement must be studied and considered. The Handbook of Research on Active Learning and Student Engagement in Higher Education focuses on assessing the effectiveness of active learning and constructivist teaching to promote student engagement and provides a wide range of strategies and frameworks to help educators and other practitioners examine the benefits, challenges, and opportunities for using active learning approaches to maximize student learning. Covering topics such as online learning environments and engagement approaches, this major reference work is ideal for academicians, practitioners, researchers, librarians, industry professionals, educators, and students.
