A researcher reports that a classroom where students received points that could be exchanged for extra recess time whenever they completed math practice problems saw an average increase of five completed homework problems per child per day compared to baseline. In terms of evaluating the effectiveness of this program, the researcher would most likely focus on.

changes in the level of response

Explanation:

The researcher would most likely focus on the changes in the level of response of child, so as to determine where to put new resources or methods to improves the changes in the level of response of the children. During evaluation, the researcher will do the following:

1.  Assess the skills development of the children

2.  Identify where to allocate new resources or methods

3.  Documentation of the level of success or changes in response of the children.

The correct answer is letter "A": changes in the level of response.

Explanation:

Researches can be focused on different aspects of the study but the variable that is to be tested must be considered as the point of reference of the study. While considering changes in the level of response, the researcher must take a sample of the target audience under regular conditions to then compare that information with the input after the variable being tested is introduced.

Thus, in the example the researcher is evaluating effectiveness through changes in the level of response since they took as a reference the number of math problems students would answer in normal conditions and when they are given extra break time if they would answer more questions, thus, receiving more points.
