This paper examines the relationship between political change and epistemologies and methodologies employed at doctorate level.
It does so by analysing the range of topics, questions and methodologies used by doctoral students at the University of Pretoria’s
Faculty of Education between 1985 and 2005—a time-frame that covers the decade before and the decade after South Africa’s
historical transition to democracy in 1994. During this period the composition of doctoral students at that faculty changed
from being largely white and male to a more diverse population in terms of gender and race. A crucial shift took place after
2000 with the arrival of a Black dean who sought to introduce a transformational shift. The paper makes use of Karmon’s notion
of epistemic environment, which refers to the way knowledge is conceptualised at institutional level. The data shows how the
authoritarian and regulated epistemic environment that shaped the conception of knowledge at the faculty until 2000 created
doctoral dissertations that aimed to correct and guide the society but lacked critical discourse and relevance to South Africa’s
political, social and educational context. While the transition to democracy in 1994 produced merely semantic changes, if
any, the strong internal initiative to change the research culture from 2000 onwards has managed to shift basic notions of
truth and knowledge and the understanding of the role and nature of research. This movement was, however, constrained by the
institution’s long-established epistemic environment. 相似文献

For some 5-year-olds, delayed kindergarten enrollment may result in long-term academic benefits. Although waiting an additional year allows for further development prior to the start of formal education, the economic costs of the next best alternatives can be significant. This study examines the impact of short-term economic fluctuations on a household's kindergarten enrollment decision. I find that during economic downturns kindergarten enrollment increases. To explore a potential mechanism through which this effect may arise, I propose an instrumental variables approach to identify the causal effect of fluctuations in household resources due to the business cycle on the timing of kindergarten enrollment. 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

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
