This document discusses how educators can enhance classroom instruction through sensory-filled and brain-based teaching strategies supported by research. It argues that while theorists have long supported these approaches, classrooms have changed little. Negative stressors in the learning environment must be removed before implementing positive changes. The document provides examples of how visual elements like movement, color, lighting can be manipulated to engage the brain's processing of visual information and enhance memory and learning.

The following paper addresses the responses that the learner has
to changes in the learning environment that enhance instruction.
While theorists have supported the notion that instruction
embedded in sensory-filled, brain-based and hands-on activities,
classrooms remain unchanged in many, if not most interactions.
What can we do to wake up teachers and administrators to make
these modifications? We believe as educators we must "come to
our senses" to bring about best quality learning environments.
The following section of this paper supports why we have come
to the conclusion that sensory and brain based teaching strategies
can no longer be left behind.
For many years scientists viewed the supporting notions of the increased role of
