Developing Insight in Engineering
Education and Practice
CHALLENGES
EXAMPLE:
Domains are unfamiliar to the user
materials &
processes
Often no hands-on physical
experience
Unfamiliar length and time scales
semiconductor chips
transistors & chips
Principles are abstract
Subtle until experienced
Ultimately must be understood in
mathematical terms
people
equipment
Systems-level behavior enlarges
complexity
Multi-level metrics
Heterogeneous, hierarchical models
Dynamic & stochastic behavior
Environments and tools for
engineering insight are limited
Education and training
Broad engineering practice
factory costs and
operations/ logistics

Learning Historian
1. Do a simulation
2. Record and save the simulation history
3. Replay the simulation history
4. Review, revise, & annotate the history
5. Share the history with peers & instructor
