TRANSCRIPT
The education approach that has been successfully implemented in a number of Israeli high schools and yielded remarkable results.
The students are first taught the graph representations, their properties and interrelations
Only then, on the basis of the representations they are taught specific engineering fields.
Such as: mechanisms
Such as: trusses
Such as: Stewart platforms
Such as: Microsystems
~
Such as: Electronics circuits
Such as: Beams

Applying the methodology for Integrated Systems
Transferring the system, containing both mechanical and electronic elements into a unified graph
representation
Now, the graph is interpreted as a representation of a single electronic circuit, which enables the electrical engineer to deal
with the whole integrated system, by himself.
