There are many variables that contribute in different ways to the effectiveness of instruction. One variable is seldom examined in detail even though it has a major influence upon learning. That variable is the physical arrangement of learners. Expert teaching can be distinguished from novice teaching by the strategic use of a variety of classroom arrangements. Which arrangement is used depends upon the purpose of the lesson.
Many lessons utilize more than one type of arrangement.
