Answer:

No. His independent variable is not controlled

Explanation:

Independent variables are those that the researcher can control and that influence, affect or determine other variables.

This type of variable is a determining factor, condition or cause for a given result, effect or consequence. It is the factor manipulated by the researcher in order to determine the relationship of the factor with the observed phenomenon, to see what influence it has on a possible result.

As we can see in the question above, it is not possible to control the independent variable in the student's experiment, for this reason his experiment cannot be considered well designed. In this experiment, it is even difficult to recognize which is the independent variable, since we have nothing to influence students' feelings about the school.
