Orphan date September 2008 The Livingtheory approach is an approach to explaining educational influences in a person s learning. Educational and other researchers are always faced with issues of validating their claims to knowledge . In the UK and elsewhere there is much interest in developing appropriate standards of judgement for assessing the quality of the knowledge generated by educational researchers. In 1995 Donald Schon advocated the development of a new epistemology for the new scholarship by Boyer and explained that this new epistemology would be generated from action research and would be a challenge to the epistemology of the modern research university Boyer, 1990 . The idea that individuals can generate their own unique explanations for their educational influences in their own learning, in the learning of others and in the learning of social formations, as their living educational theory has been gaining credibility since the establishment of the http s step.wikispaces.com Self Study of Teacher Education Practices Special Interest Group of the American Educational Research Association in 1993 S STEP, 1993 .

About systemstheory Open system disambiguation File Basic Open System Model.gif 320px thumb right Open System Model basics An open system is a system which continuously interacts with its environment. The interaction can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the concept see below . An open system should be contrasted with the concept of an isolated system which exchanges neither energy, matter, or information with its environment. The concept of an open system was formalized within a framework that enabled one to interrelate the Organismic theorytheory of the organism , thermodynamics , and Theory of Evolution evolutionary theory . ref Luhmann, Niklas.

Flatness in systemstheory is a system property that extends the notion of Controllability from LTI system theory linear systems to Nonlinearity nonlinear dynamical system s. A system that has the flatness property is called a flat system . Flat systems have a fictituous flat output , which can be used to explicitly express all states and inputs in terms of the flat output and a finite number of its derivatives. Flatness in systemstheory is based on the mathematical notion of Flat morphism flatness in commutative algebra and is applied in control theory .

Theory of functional systems is a model that describes the structure of conduct , which was established by russian and soviet biologist and physiologist Pyotr Anokhin . The principle of functional systems association of private mechanisms of the body in a holistic system of adaptive behavioral act, the establishment of integrative unity . There are two types of functional systems System of the first type provide homeostasis due to internal existing resources of the body, inside its boundaries eg blood pressure . System of a second type supports homeostasis due to a change of behavior, interaction with the outside world and are the basis of different types of behavior. Stage of the behavioral act Afferent synthesis Any excitement in the central nervous system there is in interaction with other excitations the brain analyzes these excitations. Synthesis determines the following factors Motivation Pad afferentation excitation caused by conditioned and unconditioned stimuli Situational afferentation arousal from familiar surroundings, causing a reflex, and dynamic stereotypes Memory of species and individual Decision making The formation of action result acceptor creating the ideal image and its retention goals, presumably, at the physiological level is circulating in the ring interneuron excitation Efferent synthesis or the stage of the program, integration of somatic and autonomic excitations in a single behavioral act. The action is formed, but is not manifested externally Action theory philosophy Action program execution behavior Evaluation result of the action At this stage, comparison of the actual running of the ideal image created during the formation of acceptor result of the action the reverse occurs afferentation based on a comparison of the action, or adjusted, or terminated. Meeting the needs authorizing termination of stage Choice of targets and methods of achieving them are the key factors that regulate behavior. According to Anokhin, in the structure of the behavioral ... more details
Grammar systemstheory is a field of theoretical computer science that studies system s of finite collections of formal grammar formal grammars generating a formal language . Each grammar works on a string, a so called sequential form that represents an environment. Grammar systems can thus be used as a formalization of decentralized or distributed systems of Intelligent agent agents in artificial intelligence . ref name gramsysdis cite paper first Judit last Csima title Investigations on Simple Eco Grammar Systems date 2002 url http www.cs.bme.hu csima phd1 phd1.html format HTML accessdate 2009 02 01 ref Let math mathbb A math be a simple reactive agent moving on the table and trying not to fall down from the table with two reactions, t for turning and &fnof for moving forward.
