High school classes cover a wide array of topics through the course of a school year, and students can be proficient in some areas and weak in others.
Having to determine the proficiencies and weaknesses for 120+ students every few
weeks and then providing individualized instruction is a daunting task even for
a seasoned veteran. Asking a novice teacher to do this almost seems cruel.
Collegial planning is a prerequisite,then, for making a differentiated classroom a
success. Novice teachers look forward to this process, while some veteran
teachers think of it as too much....
