The Effects of Standardized Testing on Teaching and Schools 总被引:1,自引:0,他引:1
How much influence does standardized testing exert on teaching and learning in upper elementary classrooms? Is there any difference between the impact of testing on low-SES and high-SES classrooms? How much impact does “teaching to the test” appear to have on test scores? 相似文献

A Fery radiation pyrometer was used in relative radiation measurements during a total eclipse of the sun.The experimental curve shows that the radiation is not uniform over the sun's disc.The ratio of the energy received during full sunlight to the energy received from the corona was found to he 13,000. 相似文献

The Bureau of the Census initiated the American Community Survey (ACS) in 2005. It will revolutionize the use of census data by providing annual updates to statistics that in the past were collected only every 10 years. Statistics will be published for areas of 65,000 people or more every year. The Bureau of the Census will distribute data for areas of between 20,000 and 64,999 in "3-year period averages." The first 3 year average will appear in 2008 covering 2005–2007. Subsequent data will be issued annually for the following three year periods. (e.g., 2006–2008, 2007–2009) Statistics for areas smaller than 19,999 will be published in 5-year period averages, the first to be published in 2010 covering 2005–2009. Subsequent data to be issued annually will cover 2006–2010, 2007–20011, … This paper provides background information about ACS, similarities and differences between it and the decennial census, the interpretation of statistics based upon period averages, relationships among ACS and other Bureau of the Census Surveys, and the expected future of the survey. 相似文献

Only a limited number of species have been found capable of generalized matching-to-sample (MTS) after exposure to relatively few training exemplars. We trained a juvenile, experimentally naive California sea lion (Zalophus californianus) in MTS, using a pair of three-dimensional objects as samples. Successful matching to a criterion of 90% correct or better over 2 successive sessions was attained in 12 sessions (269 trials and 70 errors). Two subsequent “partial” transfer tests, in which each of the two training objects was paired with a novel test object, and four additional transfer tests, all with novel objects, were presented following training. An 80% performance criterion over 2 successive sessions was reached, or closely approximated, in from 2 to 4 transfer sessions for all transfer tests; errors to criterion tended to be reduced across the successive novel transfer tests and were as few as five during the final two tests; and performance on the first 48 trials of the last two novel transfers was not significantly different from a near-ceiling level baseline performance measure. Neophobic responses of the sea lion to new objects precluded an unbiased evaluation of immediate (Trial 1) transfer. The sea lion’s short-term memory for sample objects was also measured. Matching performance was maintained at a level of 78% correct responses or better for delays through to 45 sec after removal of the sample object. At a 58-sec delay, the longest tested, performance declined to 69% correct responses. These retention levels are only somewhat below levels reported for dolphins and nonhuman primates tested on visual delayed MTS, but they are above levels typically reported for pigeon subjects. 相似文献

Quietly, at least beyond the awareness of many psychologists, a relatively new technology based on school‐wide behavior management strategies has emerged in special education to answer the call to build healthy communities. The success of these strategies in changing the practices of school systems and creating positive school climates may offer insights for school psychologists interested in preventing mental disorders and promoting health on a broader scale. Spreading the influence of school‐wide behavior supports to ensure that all schools provide the nurturing environment needed to promote academic and life success for all children is an important and immediate goal. Beyond the school, the challenge will be to implement and evaluate the impact of positive behavior supports in other connected communities. The present article reviews the history and present state of school‐wide behavior supports and prevention research, limitations of current practice, and opportunities for integrating school‐wide programs with psychological science and practice. © 2006 Wiley Periodicals, Inc.

Presents findings from a study into the attitudes and practices of pandemic-era early career researchers (ECRs) in regard to obtaining access to the formally published scholarly literature, which focused on alternative providers, notably ResearchGate and Sci-Hub. The study is a part of the Harbingers project that has been exploring the work lives and scholarly communication practices of ECRs in pre-pandemic times and during the pandemic, and utilizes data from two rounds of interviews with around 170 ECRs from the sciences and social sciences in eight countries. Findings show that alternative providers, as represented by ResearchGate and Sci-Hub, have become established and appear to be gaining ground. However, there are considerable country- and discipline-associated differences. ECRs' country-specific level of usage of the alternative providers is partly traceable to the adequacy of library provisions, although there are other factors at play in shaping ECRs' attitudes and practices, most notably convenience and time saving, as well as the fact that these platforms have become embedded in the scholarly dashboard. There is a dearth of evidence of the impact of the pandemic on ECRs' ways of obtaining scholarly papers. 相似文献
