adam_text	Againstand for Method Revisiting Architectural Design as Research'” Can design processes constitute genuine forms of research? Of course they can Architects, like natural scientists, con- sider the state of the art and research gaps when developing design proposals They experiment with hypotheses, test theories, and analyse results They rely on procedures which they rigidly bind to their objects of study Like researchers, many architects proceed rationally while including acts of spontaneity Their approaches are systematic and based on an immense amount of training, yet architects sometimes decide to override routines And like scientific laboratories, studios often constitute sites which are characterized as much by systematizing, categorizing, and arranging know- ledge as they are by a desire for knowledge Teaching studios indeed exhibit procedures that can be considered scientific In fact, many studios use approaches which effectively fulfil the requirements of scientific conduct— even though the people involved would likely not make such a claim The edited volume at hand provides examples of such methodologies and demonstrates their necessity The contributions and interviews urge studio teachers to reflect on and enhance the traceability, coherency, and comprehen- sibility of the methods they impart They also offer support 1 Editor: Jan Silberberger 2 Contributions by Bernhard Béhm, Johan De Walsche, Kim Helmersen, Adam Jasper, Monika Kurath, Claudia Mareis, Amy Perkins, Wolf Reuter, Hans-Jörg Rheinberger, Jeremy Waterfield, and Albena Yaneva plus interviews with Adam Caruso, Dietmar Eberle, Momoyo Kaijima, Anne Lacaton, and Elli Mosayebi i
