Online instruction is quickly gaining in importance in U.S. higher education, but little rigorous evidence exists as to its effect on student learning. We measure the effect on learning outcomes of a prototypical interactive learning online statistics course by randomly assigning students on six public university campuses to take the course in a hybrid format (with machine‐guided instruction accompanied by one hour of face‐to‐face instruction each week) or a traditional format (as it is usually offered by their campus, typically with about three hours of face‐to‐face instruction each week). We find that learning outcomes are essentially the same—that students in the hybrid format are not harmed by this mode of instruction in terms of pass rates, final exam scores, and performance on a standardized assessment of statistical literacy. We also conduct speculative cost simulations and find that adopting hybrid models of instruction in large introductory courses has the potential to significantly reduce instructor compensation costs in the long run. 相似文献

Scholars debate the relative strength of economic and ‘socio-psychological’ sources of anti-immigrant sentiment. However, the literature often fails to distinguish legal from illegal immigration and therefore overlooks a major instance in which this debate is moot. To address this issue, we develop a theory that recognizes two different modes of evaluating immigrants: “attribute-based” judgment, in which respondents weigh immigrants’ desirability based on individual characteristics—human capital, race, language ability, and so on—and “categorical” judgment, which disregards these altogether. Categorical judgments arise when a policy issue triggers blanket considerations of justice or principle that obviate considerations about putative beneficiaries’ individual merits, instead evoking overriding beliefs about the desirability of the policy as a whole or casting the entire category as uniformly deserving or undeserving. We use experimental evidence from two national surveys to show that the principal distinction between attitudes toward legal and illegal immigration is not in the relative weight of immigrants’ attributes but the much greater prevalence of categorical assessments of illegal immigration policy, much of it rooted in rigid moralistic convictions about the importance of strict adherence to rules and laws. 相似文献

We use matched employee–employer records from the teacher labor market to explore the effects of late teacher hiring on student achievement. Hiring teachers after the school year starts reduces student achievement by 0.042 SD in mathematics and 0.026 SD in reading. This reflects, in part, a temporary disruption effect in the first year. In mathematics, but not in reading, late‐hired teachers remain persistently less effective, evidence of negative selection in the teacher labor market. Late hiring concentrates in schools that disproportionately serve disadvantaged student populations, contributing to challenges in ensuring an equitable distribution of educational resources for all students. 相似文献

This special issue was written to reflect on the current role of human rights in the United Kingdom, seventy years after the United Nations General Assembly voted in favour of the Universal Declaration of Human Rights. Human rights are explored by the authors in this issue from a wide variety of perspectives. Some authors are critical of the failure of the state to implement human rights principles in practice; others lament how human rights often appear of little relevance to most people’s lives in the UK. The overall message, however, remains consistent: a human rights framework brings many positive elements to our country, ensuring it is a society where individuals, no matter their actions or characteristics, are treated with dignity. 相似文献

While Soviet oil output peaked in the early 1980s, natural gas output grew rapidly. As a result the Soviets have sought to use more natural gas as a boiler fuel, freeing petroleum for the higher priority mobile and chemical uses. Lack of depth in Soviet oil refining and lack of gas storage capacity are the two key constraints in this gas-for-oil substitution strategy. This paper considers the prospects for easing these constraints by restructuring the petroleum refining industry, and providing enough gas storage capacity to supply all gas demand during the winter.

There is an ongoing debate within the economic voting literature about whether the economy's salience systematically fluctuates over time or is constant. The recent global economic slowdown provides leverage to test the proposition that voters give greater weight to economic performance when it is weak. Data on voters' issue priorities from 2000 to 2011 shows that voters were more likely to consider the economy an important issue during periods of bad or volatile economic performance. A weak economy also focuses voter attention on corruption and crime while reducing attention to social policy and foreign affairs. Crime rates, terrorist attacks, globalization, and the level of development also affect the economy's place on the electoral agenda. Thus one impact of the recent financial downturn was a shift toward economic voting in countries where it was deepest. 相似文献
