Very colorful textbooks with lots of illustrations may also not increase learning.

Imagine a kindergarten classroom. Picture the vividly colored scalloped borders on the walls, the dancing letters, maybe some charming cartoon barnyard animals holding up “Welcome to School!” signs.
That bright, cheery look has become a familiar sight in classrooms across the country, one that has only grown over the last few decades, fed by the proliferation of educational supply stores. But to what effect?
A new study looked at whether such classrooms encourage, or actually distract from, learning. The study, one of the first to examine how the look of these walls affects young students, found that when kindergartners were taught in a highly decorated classroom, they were more distracted, their gazes more likely to wander off task, and their test scores lower than when they were taught in a room that was comparatively spartan.
The researchers, from Carnegie Mellon University, did not conclude that kindergartners, who spend most of the day in one room, should be taught in an austere environment. But they urged educators to establish standards.
“So many things affect academic outcomes that are not under our control,” said Anna V. Fisher, an associate professor of psychology at Carnegie Mellon and the lead author of the study, which was published in Psychological Science. “But the classroom’s visual environment is under the direct control of the teachers. They’re trying their best in the absence of empirically validated guidelines.”
