AB  - The creation of descriptive models using SysML is a skill-focused discipline; the outcomes of a modeling effort depend upon the abilities of the modelers contributing to it.  Ongoing shortages of skilled modelers are inhibiting the transition of systems engineering to a model-based discipline.
This paper illustrates the use of validation rules to support instruction (both stand-alone modeling exercises and a larger, collaborative modeling project).  Validation rules have proven to be effective in reducing modeler errors when added incrementally in parallel with concepts introduced in class.  The rules simplify grading (since the instructor can focus on value-added content instead of semantic correctness).  In addition, the rules conform to the Seven Keys to Effective Feedback proposed by Grant Wiggins (Seven Keys to Effective Feedback, Educational Leadership, September 2012, Volume 70, Number 1, Pages 10-16):
1.	Goal-Referenced (Error reduction/style conformance)
2.	Tangible and Transparent (Rules clearly explain what is wrong)
3.	Actionable (Error messages direct the modeler how to fix the issue)
4.	User-Friendly (Private and mark elements with errors)
5.	Timely (On demand and rapid feedback eliminates errors before they accumulate)
6.	Ongoing (Available throughout the course of modeling)
7.	Consistent (All students receive the same feedback)
The rules were continuously updated throughout the term in which they were introduced; students corrected new errors and improved their model quality as they executed their term projects.  Extracts from seven team projects will be presented and contrasted with selected past projects (subjected to the same validation rules) to demonstrate the efficacy of the approach.
