What Assessment and Research Say About the Condition of Education     

Gerald W. Bracey 《Educational Measurement》1992,11(4):5-6

Do students today know less than their parents or grandparents did as students? Are they being academically outclassed by students of other nations? Or have ideologically driven policy makers painted an unnecessarily negative picture of student achievement?  相似文献   

Chaos theory, informational needs, and natural disasters   总被引：2，自引：0，他引：2  

Timothy L. Sellnow  Matthew W. Seeger  Robert R. Ulmer 《Journal of Applied Communication Research》2002,30(4):269-292

This study applies chaos theory to a system-wide analysis of crisis communication in a natural disaster. Specifically, we analyze crisis communication during the 1997 Red River Valley flood in Minnesota and North Dakota. This flood, among the worst in modern American history, consumed entire metropolitan areas, displacing thousands of people. The conditions and decisions leading to the disaster, and the subsequent reactions are retraced. Communication related to river crest predictions (fractals), the shock at the magnitude of the crisis (cosmology episode), novel forms of reorganizing (self-organization), and agencies that aided in establishing a renewed order (strange attractors) are evaluated. Ultimately, we argue that preexisting sensemaking structures favoring rationalized, traditional views of a complex system led officials to make inappropriately unequivocal predictions and ultimately diminished the effectiveness of the region's crisis communication and planning.  相似文献

Cerebral activity prior to motion task performance: an electroencephalographic study     

D Collins  G Powell  I Davies 《Journal of sports sciences》1991,9(3):313-324

Cerebral activity, as reflected by power in the alpha waveband (8-13 Hz), was examined prior to the performance of three tasks with different effort and accuracy requirements. The study aimed to further investigate changes in activity observed in an earlier study in which expert karate performers exhibited significant increases in alpha band power during preparation for a training task. In contrast to the earlier research, the high effort task produced a significant decrease in 'alpha' power prior to performance. 'Alpha' power prior to the high accuracy task showed significant differences mediated by the outcome. Successful performance was preceded by higher levels of 'alpha' power than unsuccessful attempts. The reported use of a cognitive strategy on the first task produced a significant difference in activity, lower alpha power being associated with the use of such a technique.  相似文献

Accommodations for Students Who Are Deaf or Hard of Hearing in Large-Scale, Standardized Assessments: Surveying the Landscape and Charting a New Direction     

Stephanie W. Cawthon  The Online Research Lab 《Educational Measurement》2009,28(2):41-49

Students who are deaf or hard of hearing (SDHH) often use test accommodations when they participate in large-scale, standardized assessments. The purpose of this article is to present findings from the Third Annual Survey of Assessment and Accommodations for Students who are Deaf or Hard of Hearing. The "big five" accommodations were reported by at least two-thirds of the 389 participants: extended time, small group/individual administration, test directions interpreted, test items read aloud, and test items interpreted. In a regression analysis, language used in instruction showed the most significant effects on accommodations use. The article considers these findings in light of a more proactive role for the National Survey in providing evidence for the effectiveness of accommodations with SDHH.  相似文献
