Mrs. Kaiser is working with a small group on writing complete sentences while the rest of the class works independently on the day’s journal prompt. She politely excuses herself from the groups, walks over to a student’s desk, lowers herself to the student’s eye level and asks him to put away his cell phone or accept a consequence. Which theorist would likely agree that Mrs. Kaiser’s awareness of the behavior of general class as well as her small group is demonstrative of her “with-it-ness?”
