Researchers Want to Test a New Method of Studying High-School

Essay

Researchers want to test a new method of studying high-school course material that they hope to implement at a national level. A large group of students will be taught strategies that aid studying, and be instructed to implement the strategies on 3 separate days during 1-hour study breaks. A second group of students will also study for 3 separate days for 1-hour breaks, but without being taught memory strategies. That is, the researchers will only include half of the enrolled class in the group taught the new strategies and the other half of the class will study without any specific instruction. Then researchers will test students on their learning at the end of the study. What kind of study design does this represent? How should the sample population be selected and how generalizable would this study be?
