Interactive Lecture Demonstrations (ILDs) are designed to enhance conceptual learning in physics lectures through active engagement of students in the learning process. Real physics demonstrations are shown to students, who then make predictions about the outcomes and collaborate with fellow students by discussing their predictions in small groups. Students then observe the results of the live demonstration, compare these results with their predictions, and attempt to explain the observed phenomena. ILDs have been demonstrated through physics education research to enhance student learning of physics concepts. ILDs can be used within the traditional structure of an introductory physics course.
