The <u>correct answer</u> is:
Experiment
Explanation:
In an experiment, one group is given a treatment while at least one other group is not. After the treatment is finished, the results of the group that receive the treatment are compared with the results of the group (or groups) that do not receive the treatment, to determine if the treatment had any effect on the group.
In this problem, the different groups are the classes. Some classes use the new method, which is the treatment, while other classes do not. At the end of the year, the reading results of each class are compared to see if the treatment (new method) had any effect.
