Program Management System - 21st BCCE - Communicating Chemistry: Demonstrations in the Classroom and Beyond

Symposium Title: Communicating Chemistry: Demonstrations in the Classroom and Beyond
Descrption: The purpose of this symposium is to share a range of views regarding the use of chemical demonstrations in classrooms and in other settings and to spark interest in old and new demonstrations. Learner attitudes can be influenced by watching teachers do experiments in classroom settings. Lecture demonstrations help focus students' attention on chemical behavior and properties, and increase students' awareness and knowledge of chemistry. To approach demonstrations simply as a chance to impress students with the "magic" of chemistry is to fail to appreciate the opportunity they provide to teach scientific concepts. Lecture experiments generally involve more student participation through greater reliance on "what if" questions and suggestions from students as the teacher manipulates the chemical system. In principle and in practice, every lecture demonstration conveys the teacher's attitudes about the experimental basis of chemistry, and through them teachers can motivate their students to conduct further experimentation and lead them to understand the interplay between theory and experiment. Lecture demonstrations should not, of course, be considered a substitute for laboratory experiments, where students work directly with chemicals and equipment at their own pace and make their own discoveries. Demonstrations presented in public settings and through print and electronic media will be discussed.
