Do not contain bright colors or posters in the room. They do not contain any type of material that can help the student become interested in learning. All the lessons I teach do not contain bright colors or posters to indicate what the lesson is about. Some classes don't emphasize the right subject. For example, I have a math class that has objects on the wall, but the classroom objects don't go well with the topic I'm learning. Instead of having posters about math or equations like a normal math lesson would, there are dead animals and the periodic table. When I first walked in I thought I was in the wrong class, I thought I walked into a science class. Some teachers don't have a room, so they have to move around during the day and don't have a room that is suitable for the subject they teach. University classrooms do not have any kind of materials that would interest students in learning because they look boring and are empty. The classrooms look like they don't belong to a professor for the same reason they contain nothing on or around the wall
