The shortcomings of current research on student attrition are reviewed, and ways are described in which multiple regression, path analysis, and a recursive causal model can be used to better understand attrition. A review of the research shows that past theoretical models lack an adequate definition of variables which have resulted in their being…

This paper explores the fault-tree analysis approach to isolating failure modes within a system. Fault tree investigates potentially undesirable events and then looks for failures in sequence that would lead to their occurring. Relationships among these events are symbolized by AND or OR logic gates, AND used when single events must coexist to…

The procedures and techniques developed to evaluate a project to implement media in elementary schools are discussed. To describe the decision-making setting, two necessary conditions--understanding (high or low) and amount of change (large or small)--were paired against each other resulting in four possible evaluation settings. The situation in…

The UCLA Center for Healthier Children, Families and Communities (CHCFC) has developed the School Readiness Critical Pathways (SRCPs) as an evidence-based conceptual model that links related outcomes and strategies. This helps to organize an array of broad and diffuse evidence regarding the strategies that produce school readiness outcomes for…
