FRQ 1: School wants to implement a new policy that teachers must limit homework to a reasonable amount to reduce students stress. The school randomly assigns the teachers into two conditions. Half the teachers were required to decrease the amount of homework they assigned. The other half proceeded to keep the same amount of homework that they usually assign. At the end of the year, the administration assessed students stress levels and concluded that less homework does minimize student stress.

FRQ 2: The administration at Niceville HS believes that high standards have a positive impact on student success and design a study to investigate their hypothesis. They randomly choose half the teachers and tell them to impose strict final deadlines a week after the initial due date, and tell the other half to be more lenient in regards to late work. At the end of the year, they compare students final grades to evaluate different policies. They find that the students held to higher standards had higher overall grades. They release their findings, including student grades, to everyone in the school district in order to justify mandatory changes in district policy for all teachers the following year.
