Scientific and technological literacy (STL) is becoming one of the central planks for development through education on a global scale. Within this global thrust, design and technology in particular are gaining strength as curriculum components either as an individual subject or as contributors to a more broad and inclusive approach to learning. Today, the challenge of providing materials to consolidate a foundation of knowledge in both science and technology reaches into all countries. Development and education are inextricably linked. The key elements that still affect teachers in elementary school situations concern the development of a working subject knowledge and the confidence to deliver this to children. This challenge is being met by a generation of new materials, some with an Internet capability for distributed learning such as TechnoScience2000+. TechnoScience2000+ is a set of electronic materials developed to provide flexible learning options for a variety of potential users. The materials are not presented as a formal course, although with adaptation, they could fulfill this function. The essence of the TechnoScience2000+ materials is that they are a flexible resource in themselves. They are capable of being read online as an informal learning experience, capable of being downloaded as a file for reading as hard copy, and, crucially, capable of being altered, adjusted, and fundamentally rewritten to suit the needs of potential users. TechnoScience2000+ can thus be utilized as a mechanism for professional development with advisors, teachers, and curriculum developers rewriting materials to suit their particular in-service or preservice delivery circumstances. This notion of localized development of resources is central to the "operationalization" of STL. With the use of TechnoScience2000+, such a mechanism enables participants in STL curriculum development initiatives to invent their own "curriculum wheels," but from a basis of existing, appropriately shaped pieces rather than piles of raw materials.
