The reflective pracitioner: how professionals think in action
By Donald Schon
preface
– exploration of professional knowledge stems directly from my working life as an industrial consultant, technology manager, urban planner, policy analyst, and teacher in a professional school.
– universities are not devoted to the production and distribution of fundamental knowledge that fosters selective inattention to practical competence and professional artistry
– many use the term “academic” in its pejorative sense
– complaints about the elitism or obscurantism of the universities tend to be associated with a mystique of practical competence
– university’s familiar dichotomy between the “hard” knowledge of science and scholarship and the “soft” knowledge of artistry and unvarnished opinion.
– gain better understanding of the practical uses and limits of research-based knowledge or to help scholars who wish to take a new view on professional action
– practitioners themselves often reveal a capacity for reflection on their intuitive known in the midst of actions and sometimes use this capacity to cope with the unique and conflicted
– heart of this study is an analysis of the distinctive structure of reflection-in- action
the origins of technical rationality
– technical rationality is the heritage of positivism, the powerful philosophical doctrine that grew up in the nineteenth century as an account of the rise of science and technology and as a social movement aimed at applying the achievements of science and technology to the well-being of mankind
– institutionalized in the modern university, founded in the late 19th century when Positivism was at its height
– scientific world-view gained dominance so did he ideas that human progresses would be achieved by harnessing science to create technology for the achievement of human ends
– the scientific movement, industrialism, ad the technological program became dominant in western society, a philosophy emerged which sought both to give an account of the triumphs of science and technology and to purge mankind of the residues of religion, mysticism and metaphysics which still prevented scientific thought
– late 19th century, positivism had become a dominant philosophy
– early 20th century, in theories of the Vienna Circle, its epistemological program took on a beguiling clarity
– 2 kinds of propositions ; analytic and essentially tautological propositions of logic and mathematics or the empirical propositions which express knowledge of the world
– empirical observation, all disagreements about the world could be resolved, in principle, by reference to observable facts
– positivists became increasingly sophisticated in their efforts to explain and justify the exclusivity of scientific knowledge; empirical knowledge in irreducible elements of sensory experience
– began to see laws of nature not as facts inherent in nature but as constructs created to explain observed phenomena and science became hypothetico-deductive system.
– the success of the medical and engineering models a great attraction for social sciences (education, social work, planning and policy making, social scientists attempted to do research and apply it
– between 1963 and 1982, both the general public and the professionals have become aware of the flaws and limitations in the profession
the importance of problem setting
– technical rationality, professional practice is a process of problem solving
– must be constructed from materials of problematic situations which are puzzling, troubling and uncertain
– a conflicts of ends cannot be solved by the use of techniques derived from supplied research
– when someone reflects in action, he becomes a researcher in the practice context, non-dependent on the categories of established theory and technique
– reflection in action can proceed, even in situations of uncertainty or uniqueness, because it is not bound by the dichotomies of technical rationality
– the dilemma of rigor or relevance may be dissolved if we can develop an epistemology of practice which places technical problem solving within a boarder context of reflective inquiry; may be rigorous in its own right
Semiotics: a primer for designers
By challis hodge
– “semiotics is important for designers as it allows us to understand the relationship between signs, what they stand for, and the people who must interpret them – the people we design for.”
Overview
– semiotics can be described as the study of signs
– not signs as we normally think, instead signs in a much broader context that includes anything capable of standing for or representing a separate meaning
– “semiotics tells us things we already know in a language we will never understand”
– semiotics is important for designers as it allows us to gain insight into the relationships between signs and people who must interpret them, the people we design for.
– science of semiology seeks to investigate and understand the nature of signs and the law governing them
– semiotics adopted by disciplines such as philosophy, psychology, sociology, anthropology, literature, aesthetic and media theory, psychoanalysis and education
origins of semiotics
– Swiss linguist Ferdinand de Saussure is considered to be the founder of linguistics and semiotics
– American mathematician derived similar theories at the same time, first to use the word semiotics
– semiology therefore aims to take in any system of signs, substance or limits; images, gestures, musical sounds, objects and the complex associations of all these contents
language of language
– structuralism is an analytical method used by many semioticians
– structuralists seek to describe the overall organization of sign systems as language, search for the deep and complex structures
– social semiotics has taken the structuralist concern with the internal relations of parts within a self-contained system to the next level
– semiotics is a branch of linguistics known as semantics; common concern with the meaning of signs
– semantics focuses on what words, semiotics concerned on how signs
other traditional branches are:
– semantics: the relationships of signs to what they stand for
– syntactics (or syntax): the formal or structural relations between signs
– pragmatics: the relations of signs interpreters
– a text is an assemblage of signs (words, images, sounds or gestures)
– text usually refers to a message; has been recorded in some way
– Saussure made what is now a famous distinction between language (langue) and speech (parole)
– Language refers to the system of rules and conventions which is independent individual users
– Speech refers to its use in “particular instance”
– meaning of a sign is not in its relationship to other signs within the language system but in the social context of its use
– a synchronic system of language may be to exist only from the point of view of the subjective consciousness of an individual speaker belonging to some particular language group
– the study of semiotics needs to account for the relationships of the symbols and the social context or context of use
understanding design as a dialogue
“ the study of signs is the study of the construction and maintenance of reality. To decline such a study is to leave to others the control of the world of meanings.”
– the deeper our understanding and awareness of these factors, the better our control over the success of the work products we create
– becoming aware of these systems and rules and learning to master them is the true power of visual communication and design
