"Imagine a party of time travellers from an earlier century, among them
one group of surgeons and another of school-teachers, each group eager
to see how much things have changed in their profession a hundred or
more years into the future.  Imagine the bewilderment of the surgeons
finding themselves in the operating room of a modern hospital.  Although
they would know that an operation of some sort was being performed, and
might even be able to guess at the target organ, they would in almost
all cases be unable to figure out what the surgeon was trying to
accomplish or what was the purpose of the many strange devices he and
the surgical staff were employing .  The rituals of antisepsis and
anaesthesia, the beeping electronics, and even the bight lights, all so
familiar to television audiences, would be utterly unfamiliar to them.

 The time travelling teachers  would respond very differently to a
modern elementary school classroom   They might be puzzled by a few
strange objects.  They might notice that some standard techniques had
changes - and would likely disagree amongst themselves about whether the
changes they saw were for the better or the worse - but they would fully
see the point of most of what was being attempted and could quite easily
take over the class"
