Teachers in this country have generally been trained either to approach mathematics like a creative activity or that they should force students to memorize rules and principles without truly understanding how to apply them.
a) to approach mathematics like a creative activity or that they should force students to memorize rules and principles
b) to approach mathematics like a creative activity or to force students to memorize rules and principles
c) to approach mathematics as a creative activity or to force students to memorize rules and principles
d) that they should approach mathematics as a creative activity or to force students to memorize rules and principles
e) that they should approach mathematics like a creative activity or that they should force students to memorize rules and principles
Between b and c (like vs as), why don't we use the word "like" when it is comparing to nouns (mathematics and creative activity). Also for "as", isn't there suppose to be two verbs in the comparison?
Thanks!
