Think "pull" and "push".

With for-each one pulls nodes from the source tree and the 
instruction supplies the one result tree construction rule used for 
all nodes pulled.

With apply-templates one pushes nodes from the source tree at the 
stylesheet and the processor finds the template rule with the result 
tree construction rule for each individual node pushed.

These characterizations seem to be received well by my students.

I hope this helps.
