Conventional approaches to early assessment and intervention for young school children focus primarily upon notions of general intelligence, academic readiness, personality, and perceptual integrity. However, such concepts are grounded largely in hypothetical constructs that provide little information to those carrying out enrichment and remediation programs. Alternatively, the concept of learning style focuses upon the phenomenology of potentially changeable or teachable behaviors manifested in common learning situations. The 16-item Study of Children's Learning Styles rating scale was completed by teachers for 1,513 kindergarten children from diverse community, racial, socioeconomic, and religious backgrounds. Principal components factor analysis with varimax rotation revealed three distinct styles of learning-related behavior; i.e., Avoidant, Inattentive, and Overly Independent. These dimensions were found to retain substantial internal consistency, as well as retest and interobserver reliability. Learning styles were validated against the criteria of teacher-assigned grades and standardized achievement scores gathered one year later, and were compared to a concurrent measure of general intelligence. Each style was related to other behavioral dimensions not devoted exclusively to the learning process. 相似文献

This paper describes an applied document filtering system embedded in an operational watch center that monitors disease outbreaks worldwide. At the initial time of this writing, the system effectively supported monitoring of 23 geographic regions by filtering documents in several thousand daily news sources in 11 different languages. This paper describes the filtering algorithm, statistical procedures for estimating Precision and Recall in an operational environment, summarizes operational performance data and suggests lessons learned for other applications of document filtering technology. Overall, these results are interpreted as supporting the general utility of document filtering and information retrieval technology and offers recommendations for future applications of this technology. 相似文献
