Unlike Most Classrooms That Are Filled with Brightly Colored Posters

Unlike most classrooms that are filled with brightly colored posters and bulletin boards, Mrs. Williams keeps at least half the wall space empty. She uses soft, muted colors in her decorating, and prefers to display the children's artwork instead of commercial posters. Which of the following benefits does this approach provide?

A) Using children's art and keeping the walls blank takes less time and money for the teacher.
B) Many children find bright, crowded classrooms visually overstimulating. A more subtle approach is calming and creates a comfortable learning environment.
C) Using the children's artwork impresses parents and administrators.
D) Mrs. Williams doesn't have to worry about storing posters from year to year.
