Aresearcher is exploring the effect of classroom environments on learning. two identical psy230 courses are being taught by the researcher. one is taught in a room with glass walls which allows students to see persons walking past, the other is in a similarly configured room with opaque walls. students' learning is assessed at the end of the semester with a comprehensive examination. the independent variable in this scenario is the:

Class room environment ( i.e the type of wall)

Explanation:

Here, it is given that the two identical courses are being taught to the students that means the course is not varying.

Also, the same researchers are teaching the students that means the researchers are also not variables.

Therefore, the only thing that is varying in the whole research is the class room environment i.e the the walls of the classrooms.

In the glass walls there will be more distractions while in the opaque walls it will not be much.

Therefore, the classroom environment is the independent variable in the research.

they all focused on themes about the inevitability of death.
