Enhancing Education Using Constraint Graph-based
Knowledge Representations Cowan et al.
Initial results with high school physics class
Students using constraint graphs did 70 better
I believe that this process will be helpful to
others because I have been doing the same thing
in my head to organize and understand the
different equations and to help me solve the
problems successfully. student comment

ME 8813 Modeling Simulation in DesignCourse
Topics

• Context
• Knowledge and Information in Product Development
• How this course fits into big picture of product
  development
• Information Modeling
• Structure of Information concepts and
  (semantic) relationships
• Spring 2005 ½ lecture on SysML ... more under
  consideration in future offerings
• Discrete Event Simulation
• Model in which variables change values only at
  discrete moments in time
• Modeling of Energy-based systems
• Models of physical systems in which the energy
  exchange is captured as a function of time
• Uncertainty in Models
• Representing and computing with uncertain
  knowledge and information
• Model validation

  Parametrics Work

Note The SysML notation used in these slides
roughly corresponds to SysML draft v0.9 plus more
recent updates and experimental variations. We
intend to update these examples with the final
official notation when v1.0 that becomes
available.
