Answer:
The design can most accurately be classified as experimental.
Explanation:
In educational psychology, experimental design refers to the way in which participants are allocated to the different conditions in order to find results. The most common way to do it is by dividing participants into two different groups, the experimental and the control groups. Change is introduced only to the experimental group so that the results obtained from the two groups can be compared. That is precisely what Ms. Flores does. One of her groups, the control one, keeps on practicing as usual. The experimental group, on the other hand, tries the new conditioning program. After some time, she measures their speed and compares the results to verify if the new conditioning program truly causes improvement.
