This paper considers the teaching aspect in the evolution of mechanisms and
machines drawing with the aim to recognize developments and changes in the
teaching approaches of what we now call Theory of Mechanisms. The evolutio
n of mechanism schemes has been reviewed through significant examples drawn
from a few authors, who have been selected to point out basic historical d
evelopments. It is worth noting that over time mechanism design teaching ha
s been strongly restricted to fundamentals and past methodologies so that g
enerally current schemes for designing have not been and were not included
in regular teaching curricula.
