The first stanza of the poem you quote seems to indicate that the audience is a student or students.  The use of the second person "your" is unusual in imaginative literature, and indicates that the speaker is addressing a single student, or a group of students, since "your" can also be plural.  The opening stanza also may indicate that the student or students have only a simplistic understanding of poetry, aware of the "rules" and such of poetry, but no more. 

In the third stanza, the "gleefully cheer" suggests younger students.  Even if, for instance, high school students like going outside for class, they wouldn't be expected to gleefully cheer.  Of course, in addition to indicating the young age of the students, the stanza may indicate that the students are more interested in where the class takes place than in what the class is about.  This may be a negative reflection on the students.
