The High/Scope Preschool Curriculum is an open-framework model derived from Piagetian theory. The curriculum originated from one of the first early childhood intervention programs of the 1960s, the High/Scope Perry Preschool Project, and was further developed with funding as a demonstration project in the First Chance Network for handicapped preschoolers. Through designated key experiences for children, teaching and parenting strategies, and child-observation materials, the curriculum provides a decision-making framework. Within this framework, teachers design a classroom program that reflects the expressed needs and interests of the children being served. This approach emphasizes the identification of the child's status on a developmental continuum by examining his/her strengths and accomplishments. The project views discrepancies in behavior between disabled and nondisabled age peers as developmental delays, not as deficiencies. Basing their tasks on this orientation, teachers initiate developmentally appropriate experiences in the classroom that reflect the basic long-range goals of the project. These goals are to develop children's ability to use a variety of skills in the arts and physical movement; to develop their knowledge of objects as a base of educational concept; to develop their ability to speak, dramatize, and graphically represent their experiences and communicate these experiences to other children and adults; to develop their ability to work with others, make decisions about what to do and how to do it, and plan their use of time and energy; and to develop their ability to apply their newly acquired reasoning capacity in a wide range of naturally occurring situations and with a variety of materials. The plan-do-review sequence encourages children to achieve these goals by involving them in decision-making and problem-solving situations throughout the day. The teacher's role is to support the children's decisions and encourage them to extend learning beyond the original plan. Similarly, teachers rely on a basic room arrangement and daily routine designed to stimulate and support active learning.
