Nuthmann, Conrad F., "The Public School System: A Dynamic Model of Community Standards, Students, Teachers, and Resources", 1994

ua435

Problem Public school systems have server problems that are rooted in the fundamental dynamics of the system. A list of problems include: -Declining performances -Diminished Standards -Relativistic performance assistance -Student motivation -Confused objectives and curicula -Teaching fads -Cultural heterogeneity -non-educational responsibilities of schools -Social pathology -Administrative confusion -Disenchantment with public school Purpose/Objective The objective of the effort was to reduce the public education system to its basic elements: standards, students, teachers and resources; and then to analyze the dynamics of such a system as it responded to three fundamental kinds of disruption: resources waste, teacher diversion, and student distraction. Method/Approach A system dynamics model of a public education system was constructed using STELLA II. It was exercised according to a 5X4 factorial experimental design that examined the behavior of 12 dependent variables under the 20 conditions specified by the factorial design. Findings Results were summarized as a series of parametric plots. For example, plotting Performance X Cost per Performance point gained across all conditions of degradation revealed a significant interaction effect. That is, performance cost at high standards are much less per unit of performance gained, (and much less sensitive to disruption) than those at low standards. Eight major findings are discussed, and a discussion of each of the major identified problems is offered.
