• Q11

What is this study design called? Researchers want to observe how different methods of teaching work for high school students. Since high school students already have assigned classes and times for each class, it would not make sense to separate them. Because of this, each teacher of a certain subject would be instructed to teach in a different way than others to test how well the predetermined methods work.
