"Modeling Dynamics Systems: Lessons for a First Course" provides a set of tools that enable educators at the secondary and college levels to teach a one-semester or one-year course in System Dynamics. These lessons are also useful for trainers in a business environment. Developed for beginning modelers, the lessons contained in this book can be used for a core curriculum or for independent study. A set of student lessons, a teacherís guide with all the answers to the student lessons (and additional comments to the instructor), as well as a CD containing all of the models, is provided with the book. Participants in the workshop will have a chance to build some simple models and gain a sense of the progression leading to a more sophisticated model. Student work will be demonstrated and a CD containing samples of student work and their technical papers will be provided to all participants.
