Supporting self-evaluation in local government via Knowledge Discovery and Data mining     

Hye-Chung Kum  Dean F. Duncan  C. Joy Stewart 《Government Information Quarterly》2009

The business sector has already recognized the importance of information flow for good management, with many businesses adopting new technology in data mining and data warehousing for intelligent operation based on free flow of information. Free flow of information in government agencies is just as important. For example, in child welfare, entities that fund social services programs have increasingly demanded improved outcomes for clients in return for continued financial support. To this end, most child welfare agencies are paying more attention to the outcomes of children in their care. In North Carolina, many county departments of social services have successfully adopted the self-evaluation model to monitor the effects of their programs on the outcomes of children. Such efforts in self-evaluation require good information flow from state division of social services to county departments of social services. In this paper, we propose a comprehensive KDD (Knowledge Discovery and Data mining) information system that could upgrade information flow in government agencies. We present the key elements of the information system and demonstrate how such a system could be successfully implemented via a case study in North Carolina. The next generation infrastructure in digital government must incorporate such information system to enable effective information flow in government agencies without compromising individual privacy.  相似文献

Monitoring Classroom Behavior in Early Childhood: Using Group Observation Data to Make Decisions     

Delilah Krasch  Deborah Russell Carter 《Early Childhood Education Journal》2009,36(6):475-482

Monitoring and evaluating classroom behavior in early childhood for the purpose of improving teaching and learning is critical. There is a clear link between social behavior and academic learning. Classrooms where students are following expectations, engaging academically, and transitioning effectively between activities are classrooms where students spend more time accessing instruction. In order to make efficient and effective decisions for class-wide supports, data should be collected on the class as a whole. With accurate data, interventions can be implemented for the whole group that will increase instructional time. In this paper we propose quick and efficient data collection methods for three key behaviors: following expectations, engaging academically, and transitioning amongst activities. With minimal disruption and effort, teachers can collect data that will enable them to support appropriate behaviors, ensure that students understand behavioral expectations, maintain an organized environment, improve positive interactions, and decrease the number of students needing intensive, individualized supports.  相似文献
