Returning to the research problem in Exercise 2, suppose you also want to know if the two methods of teaching French have differential effects for boys and girls. Outline the experimental design that would permit you to answer this question at the same time.

Exercise 2

Consider the following research question: Does teaching the fi rst year of French through an oral–aural approach, rather than the grammar-transformational method, alter pupil performance on a standardized year-end test in grammar, reading, and vocabulary?

a. Identify the ideal experiment to answer this question, assuming that there are no administrative or other restrictions.

b. Identify the experiment that would most likely be required in the typical high school setting.

c. State the relative advantages of the ideal experimental design compared with the design.
