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…

Data are used from the individualized math component of an operating educational system to validate the basic assumptions underlying EDSIM 1, a computer simulation model that traces the interaction of three probabilistic elements in an educational program and produces synthetic output regarding this interaction in terms of student time in the…
