Systems thinking has been likened to a science of organizing complexity. Few problems in education have the elements of complexity as that of curriculum. Indeed, within the educational system, the subsystem, curriculum, presents us with a designor problem solvingchallenge that requires tools and approaches that have yet to be fully explored. This paper discusses the basic systems elements of curriculum design and management and highlights the problem underlying the development of curricula that are based on networks of learning standards and benchmarks. Project 2061 Benchmarks for Science Literacy [1] is used as an example of such interconnected learning benchmarks. The first of a suite of tools, TraxLiteracy [2], which tracks benchmarks, curriculum activity blocks and student achievement is used to illustrate the dimensions of the problem and the elements of managing benchmark-based curricula . The implications for education at every level from elementary to university is discussed. 1 Background a systems definition of curriculum The educational literature abounds with definitions of ‘curriculum’. The assortment of contemporary definitions ranges form those of a parent, Mrs. Stephens, “Curriculum is an eclectic framework of learning opportunities, resources, and instructional strategies that empower students to aspire to and to attain national and state standards, learner outcomes, specific teacher-based objectives, while addressing individual abilities.”....

Spector (Editors) to that of a Board of Education [3], “A series of planned instruction that is coordinated and articulated in a manner designed to result in the achievement by students of specific knowledge and skills and the application of this knowledge”, to that of George J. Posner and Alan N. Rudnitsky [4], is not a process. . . . A more precise view of curriculum--and the common understanding of curriculum among lay people--is that it is what is taught in school or what is intended to be learned. It does not refer to what is to be done in school or what is to happen in the learning process. Curriculum represents a set of intentions, a set of intended learning outcomes. The first definition sees curriculum as a set of resources and strategies aimed at empowering students to achieve various standards; the second emphasizes coordination and planning and the third puts the emphasis on the outcomes themselves. It is important that we establish a working definition at the outset. Let’s try viewing curriculum as a subsystem of the education system. There are various definitions of the term system. This paper will consider the definition of Robertshaw, Rerick and Mecca[5], “ A system is a time-varying configuration of people, hardware and procedures organized to accomplish a certain function(s).” Viewing curriculum as a system or (subsystem of education), we can begin with a simple definition, Curriculum is a time-varying configuration of teaching-learning activities organized to accomplish a set of benchmarks for student accomplishment. In this paper we will use the term benchmarks, learning objectives and standards somewhat interchangeably referring to them generally as benchmarks or BMs. Likewise, we will refer to teaching-learning activities as curriculum activity blocks or CABs. CABs involve students, teachers, parents, and other participants in a planned learning activity such as a learning unit, an extended lesson, a group or individual project, etc. The specification of a CAB will be discussed later. For purposes of introduction, as long as we keep the aforementioned agreements in mind, we can use as our definition of curriculum, Curriculum is a time-varying configuration of learning activity blocks (CABs) organized to accomplish a set of benchmarks BMs. © 2004 WIT Press, www.witpress.com, ISBN 1-85312-712-4 The Internet Society: Advances in Learning, Commerce and Security, K.
