Notes:
A process is knowledge about how something works. It answers the question, "What happens?" Processes are often taught at an information-about level. The process is sometimes demonstrated but the learner frequently has an incomplete or inaccurate mental model of the process.
The components of a process include its name and description, a consequence that is defined as a change in a property value with the corresponding change in the portrayal of the entity (what happens?), and a set of conditions that is defined as values on properties (when?). A knowledge structure for a processes causal network is illustrated in Figure 1. This structure is called a PEAnet for Process, Entity, Activity Network. This structure is a very generic knowledge structure that can be used to represent almost any process. Processes are defined in terms of properties. A condition for a process is some value on a property. A consequence for a process is a change in the value of a property. When the value of a property of an entity changes the portrayal, either its appearance or its behavior, also changes in a corresponding way.
