Since the start of the early 1990s, an increasing number of people are interest in supporting the complex tasks of the curriculum development process with computer-based tools. "Curriculum development" refers to an intentional process or activity directed at (re)designing, developing, and implementing curricular interventions in schools, colleges, or corporate education. The term "curricular intervention" serves as a common denominator for curricular products, programs, materials (varying from teacher and student/trainee materials), procedures, scenarios, processes, and the like. A key issue and major challenge in curriculum development is how curricular interventions should be developed in order to achieve a satisfying balance between the ideals of a curriculum change and their realization in practice. This paper provides background information on the roots of computer-based tools for curriculum developers, provides an overview of those tools currently available in the United States and abroad (especially Australia and The Netherlands) and describes probable future trends.
