Panel 1: As Miss Edwards drones on about the wing of an aircraft, one of her charges throws a paper airplane at the blackboard while other children laugh because of course they do.
Panel 2: Her response is to turn writing anything into a punishment to be feared and avoided by informing some kid named James that he's just volunteered to write a six-page essay on the principle of flight. Given that she tells him to see her after school, I guess we know when she wants to see it.
Panel 3: She tells Chris and Dana to stop talking, Jeff to put his feet down and for Lesley to save the apple for lunch. When she has their attention, she'll continue.
Panel 4: She then impotently thought-bubbles that she could teach better if she didn't have to discipline.
Summary: We've just seen an example of poor human resource management. They don't take her seriously because she probably makes a pet of one discipline problem while leaving them out to dry.
