Epistemology is the branch of philosophy concerned with knowledge. Epistemologists study the nature, origin, and scope of knowledge, epistemic justification, the rationality of belief, and various related issues. Debates in (contemporary) epistemology are generally clustered around four core areas:
- The philosophical analysis of the nature of knowledge and the conditions required for a belief to constitute knowledge, such as truth and justification
- Potential sources of knowledge and justified belief, such as perception, reason, memory, and testimony
- The structure of a body of knowledge or justified belief, including whether all justified beliefs must be derived from justified foundational beliefs or whether justification requires only a coherent set of beliefs
- Philosophical skepticism, which questions the possibility of knowledge, and related problems, such as whether skepticism poses a threat to our ordinary knowledge claims and whether it is possible to refute skeptical arguments
Learning theory describes how students receive, process, and retain knowledge during learning. Cognitive, emotional, and environmental influences, as well as prior experience, all play a part in how understanding, or a worldview, is acquired or changed and knowledge and skills retained.
In the interdisciplinary fields of sociology, social ontology, and communication theory, social constructionism serves as a theoretical framework that suggests various facets of social reality—such as concepts, beliefs, norms, and values—are formed through continuous interactions and negotiations among society's members, instead of the pure objective observation of physical reality. The theory of social constructionism posits that much of what individuals perceive as 'reality' is actually the outcome of a dynamic process of construction influenced by social conventions and structures.
Social constructivism is a sociological theory of knowledge according to which human development is socially situated, and knowledge is constructed through interaction with others. Like social constructionism, social constructivism states that people work together to actively construct artifacts. While social constructivism focuses on the artifacts (constructs) that are created through social interactions, social constructionism focuses on social constructions as active processes, rather than outcomes.
Constructivism is a theory in education which posits that individuals or learners do not acquire knowledge and understanding by passively perceiving it within a direct process of knowledge transmission, rather they construct new understandings and knowledge through experience and social discourse, integrating new information with what they already know. For children, this includes knowledge gained prior to entering school. It is associated with various philosophical positions, particularly in epistemology as well as ontology, politics, and ethics. The origin of the theory is also linked to Swiss developmental psychologist Jean Piaget's theory of cognitive development.
Ernst von Glasersfeld was a philosopher, and emeritus professor of psychology at the University of Georgia, research associate at the Scientific Reasoning Research Institute, and adjunct professor in the Department of Psychology at the University of Massachusetts Amherst. He was a member of the board of trustees of the American Society for Cybernetics, from which he received the McCulloch Memorial Award in 1991. He was a member of the scientific board of the Instituto Piaget, Lisbon. Glasersfeld is known for the development of radical constructivism.
Radical constructivism is an approach to epistemology that situates knowledge in terms of knowers' experience. It looks to break with the conception of knowledge as a correspondence between a knower's understanding of their experience and the world beyond that experience. Adopting a skeptical position towards correspondence as in principle impossible to verify because one cannot access the world beyond one's experience in order to test the relation, radical constructivists look to redefine epistemology in terms of the viability of knowledge within knowers' experience. This break from the traditional framing of epistemology differentiates it from "trivial" forms of constructivism that emphasise the role of the knower in constructing knowledge while maintaining the traditional perspective of knowledge in terms of correspondence. Radical constructivism has been described as a "post-epistemological" position.
Second-order cybernetics, also known as the cybernetics of cybernetics, is the recursive application of cybernetics to itself and the reflexive practice of cybernetics according to such a critique. It is cybernetics where "the role of the observer is appreciated and acknowledged rather than disguised, as had become traditional in western science". Second-order cybernetics was developed between the late 1960s and mid 1970s by Heinz von Foerster and others, with key inspiration coming from Margaret Mead. Foerster referred to it as "the control of control and the communication of communication" and differentiated first order cybernetics as "the cybernetics of observed systems" and second-order cybernetics as "the cybernetics of observing systems".
Constructionist learning is the creation by learners of mental models to understand the world around them. Constructionism advocates student-centered, discovery learning where students use what they already know, to acquire more knowledge. Students learn through participation in project-based learning where they make connections between different ideas and areas of knowledge facilitated by the teacher through coaching rather than using lectures or step-by-step guidance. Further, constructionism holds that learning can happen most effectively when people are active in making tangible objects in the real world. In this sense, constructionism is connected with experiential learning and builds on Jean Piaget's epistemological theory of constructivism.
Lifeworld may be conceived as a universe of what is self-evident or given, a world that subjects may experience together. The concept was popularized by Edmund Husserl, who emphasized its role as the ground of all knowledge in lived experience. It has its origin in biology and cultural Protestantism.
Constructivist teaching is based on constructivist learning theory. Constructivist teaching is based on the belief that learning occurs as learners are actively involved in a process of meaning and knowledge construction as opposed to passively receiving information.
Enactivism is a position in cognitive science that argues that cognition arises through a dynamic interaction between an acting organism and its environment. It claims that the environment of an organism is brought about, or enacted, by the active exercise of that organism's sensorimotor processes. "The key point, then, is that the species brings forth and specifies its own domain of problems ...this domain does not exist "out there" in an environment that acts as a landing pad for organisms that somehow drop or parachute into the world. Instead, living beings and their environments stand in relation to each other through mutual specification or codetermination" (p. 198). "Organisms do not passively receive information from their environments, which they then translate into internal representations. Natural cognitive systems...participate in the generation of meaning ...engaging in transformational and not merely informational interactions: they enact a world." These authors suggest that the increasing emphasis upon enactive terminology presages a new era in thinking about cognitive science. How the actions involved in enactivism relate to age-old questions about free will remains a topic of active debate.
Epistemology or theory of knowledge is the branch of philosophy concerned with the nature and scope (limitations) of knowledge. It addresses the questions "What is knowledge?", "How is knowledge acquired?", "What do people know?", "How do we know what we know?", and "Why do we know what we know?". Much of the debate in this field has focused on analyzing the nature of knowledge and how it relates to similar notions such as truth, belief, and justification. It also deals with the means of production of knowledge, as well as skepticism about different knowledge claims.
In psychology, constructivism refers to many schools of thought that, though extraordinarily different in their techniques, are all connected by a common critique of previous standard approaches, and by shared assumptions about the active constructive nature of human knowledge. In particular, the critique is aimed at the "associationist" postulate of empiricism, "by which the mind is conceived as a passive system that gathers its contents from its environment and, through the act of knowing, produces a copy of the order of reality".
Björn Kraus is a German philosopher, who unfolds epistemological theories for social work. He therefore picks up on the doubt about the possibilities of human perception, a topic that has been emphasized over and over in occidental philosophy. He thus stands in tradition of a skepticism as for example defined by Immanuel Kant and Ernst von Glasersfeld.
Constructivism has been considered as a dominant paradigm, or research programme, in the field of science education since the 1980s. The term constructivism is widely used in many fields, and not always with quite the same intention. This entry offers an account of how constructivism is most commonly understood in science education.
Relational constructivism can be perceived as a relational consequence of radical constructivism. In contrary to social constructivism, it picks up the epistemological threads and maintains the radical constructivist idea that humans cannot overcome their limited conditions of reception. Therefore, humans are not able to come to objective conclusions about the world.
Decolonization of knowledge is a concept advanced in decolonial scholarship that critiques the perceived hegemony of Western knowledge systems. It seeks to construct and legitimize other knowledge systems by exploring alternative epistemologies, ontologies and methodologies. It is also an intellectual project that aims to "disinfect" academic activities that are believed to have little connection with the objective pursuit of knowledge and truth. The presumption is that if curricula, theories, and knowledge are colonized, it means they have been partly influenced by political, economic, social and cultural considerations. The decolonial knowledge perspective covers a wide variety of subjects including philosophy, science, history of science, and other fundamental categories in social science.
Pragmatic constructivism (PC) is a philosophical framework of how people create, utilise and share intelligence about the world in which they exist, in order to take successful action. To do so they construct a framework they consider reality to guide their action.
Applied epistemology refers to the study that determines whether the systems of investigation that seek the truth lead to true beliefs about the world. A specific conceptualization cites that it attempts to reveal whether these systems contribute to epistemic aims. It is applied in practices outside of philosophy like science and mathematics.
