As a significant step in the consolidation of the importance of technology in education, the Flemish Government recently (September 2007) introduced a formal technology curriculum for schools. This compulsory curriculum replaces already existing but non-binding technology guidelines and is an important action in the Flemish policy of educational technology support. The introduction of a technology curriculum brings educational technology in schools to a turning point: Technology is no longer considered as being dependent on teachers' individual efforts or willingness, but is becoming compulsory at the school level. The Flemish educational technology curriculum is written in terms of attainment targets. These targets are minimum objectives concerning the knowledge, insight, skills, and attitudes the government regards as necessary for and attainable by pupils at different educational levels. The formulation of a compulsory technology curriculum opens new perspectives for Flemish schools when working on putting technology into practice. Schools are challenged to translate the technology curriculum into concrete teaching and learning activities. For this purpose, they can use the online tool PICTOS (Planning for ICT on School) to establish their school-based technology plan. This article discusses the five design principles which, at the same time, act as characteristics of PICTOS. (Contains 1 table and 1 figure.)
