ArtifactsThere are five primary types of content (artifacts of knowledge): facts, concepts, processes, procedures, and principles.FactsSpecific and unique data or instance.ConceptsA class of items, words, or ideas that are known by a common name, includes multiple specific examples, shares common features. There are two types of concepts: concrete and abstract.ProcessesA flow of events or activities that describe how things work rather than how to do things. There are normally two types: business processes that describe work flows and technical processes that describe how things work in equipment or nature. They can be thought of as the big picture, of how something works.ProceduresA series of step-by-step actions and decisions that result in the achievement of a task. There are two types of actions: linear and branched.PrinciplesGuidelines, rules, and parameters that govern. It includes not only what should be done, but also what should not be done. Principles allow one to make predictions and draw implications. Given an effect, one can infer the cause of a phenomena. Principles are the basic building blocks of causal models or theoretical models (theories).The above artifacts (content) are then, in turn, used in the knowledge creation process to create two types of knowledge: declarative and procedural. Declarative KnowledgeDeclarative models refers to representations of objects and events and how these knowledge and events are related to other objects and events. They focus on the why rather than the how. It allows us to think and talk about the world. Declarative models include propositions and schemata.
Propositions can, in turn, become propositional networks that contain a number of interrelated facts, such as, "Don is reading a reference book while writing this article on a computer." Such propositions and propositional networks would look something like this:
Schemata are composed of conceptional knowledge, plan-like knowledge, and causal knowledge.
For example, the concept "car" can be linked to "tires" and "engines." Thus, a instance can be classified as a car or not a car.
Experts possess more powerful concepts in their domain than novices that help them to solve problems. These concepts give them patterns for labeling various memory states, which allow them to classify problems according to their solution mode or deep structure. Where as novices typically classify problems according to their surface structure or superficial feature.
Procedural KnowledgeProcedural models focus on tasks that must be performed to reach a particular objective or goal. It is characterized as knowing how. Procedural knowledge is often difficult to verbalize and articulate (tacit knowledge) than declarative knowledge.
Procedural knowledge emphasizes hierarchial or information processing approaches based upon productions. A combination of productions create production systems.
