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.”

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.

(5) etc.
b) Demonstrations (scenarios operating on test case models)
i) Multi-tool interoperability
(1) Homogeneous (exchanges among tools with similar purposes)
(a) Requirements: Artisan-Embedded Plus-Ilogix-Telelogic-UGS ...
(b) Parametrics: Artisan-Embedded Plus-Ilogix-Telelogic-UGS ...

(2) Heterogeneous (exchanges among tools with different purposes)
(a) Solving parametrics
(b) Requirements flow-down to ECAD and MCAD
(c) etc.
2) Evaluations / recommendations for updates / extensions to SysML
(conceptual-level and development-level items based on above experiences)
