Understanding Equilibrium: The Study of Complex Systems. Final Project Report.
Duckworth, Eleanor; And Others
The Educational Technology Center (ETC) Complex Systems Project was initiated to explore ways of using computers to help students understand systems which have often proven too complex for most high school students to understand. Preliminary work concentrated on the cognitive processes involved in modeling simple systems. This paper describes an experiment involving an actual system of helium-filled balloons and a computer simulation of the same system with which students practiced changing equilibrium states and collected information about various aspects of the system that affected the equilibrium of the balloon. Researchers used observation and interview techniques to learn how the students perceived which elements in the system were critical to equilibrium. Included are: (1) experimental procedures; (2) a discussion of the student experiment; (3) transcripts of student problem solving; (4) a description of a computer simulation of the balloon problem; and (5) a discussion of experimental results.
