RT Journal Article SR Electronic T1 A Framework for Theory Applicable to the Education of Landscape Architects (and Other Environmental Design Professionals) JF Landscape Journal FD University of Wisconsin Press SP 136 OP 143 DO 10.3368/lj.9.2.136 VO 9 IS 2 A1 Carl Steinitz YR 1990 UL http://lj.uwpress.org/content/9/2/136.abstract AB This paper presents a six-level framework that organizes questions associated with a landscape design problem. Each has an associated modeling type. The framework can be used to integrate applicable knowledge and also to identify areas where contributions of theory are needed. It is proposed that an appropriate project method can result (in large part) from the articulation of the six levels of models in reverse order from, and prior to, the actual carrying out of a project. It can be further argued that both effectiveness and efficiency are dependent upon the progression of the project through all six levels. Finally, if the linking of question and model is useful, the framework can be the basis of a strategy of professional education.
