A number of classroom-based teaching approaches have been developed to enhance children's learning. Many of these approaches follow structured and clearly defined teaching methods, are individualized according to the learning needs and progress of each child, and incorporate data-based decision making. This includes the Training and Education of Autistic and other Communication Handicapped Children (TEACCH) structured teaching program, precision teaching, and direct instruction. The primary purpose of this chapter is to provide you with an overview of the TEACCH approach to structured teaching. However, other structured, classroom-based teaching approaches including precision teaching and direct instruction, will also be described. This will include a description of the historical and theoretical foundation of these approaches, the principles that underpin these approaches, strategies for implementing programs within the classroom context, and an evaluation of the underlying evidence base.
