This paper describes the SIGGS Theory Model as it applies to educational systems. This model, designed to simulate a wide variety of systems, uses sets (S), information (I), graph theory (G), and general systems (GS). The educational system is viewed as a set; in one example this set consists of teacher, student, curriculum, and setting. This…

Computer-based information search services (ISSs) of the type that provide online literature searches are analyzed from a systems viewpoint using a continuous simulation model. The methodology applied is "system dynamics," and the system language is DYNAMO. The analysis reveals that the observed growth and stagnation of a typical ISS can…

An analysis of computer-based search services (ISSs) from a system's viewpoint, using a continuous simulation model to reveal growth and stagnation of a typical system is presented, as well as an analysis of decision making for an ISS. (Author/MBR)

Two types of questions may be asked in educational inquiry: educological ones--those seeking descriptions of educational events, and programmatic ones--those seeking prescriptions for educational interventions. Quantitative educology is described as consisting of three branches: the philosophy, science, and praxiology of education. The SIGGS…
