Reality versus Simulation 总被引：1，自引：1，他引：1

A systematic study of the implementation of simulation hardware (TIMS) replacing software (MATLAB) was undertaken for advanced undergraduate and early graduate courses in electrical engineering. One outcome of the qualitative component of the study was remarkable: most students interviewed (4/4 and 6/9) perceived the software simulations as “fake”. Professionals, on the other hand, find such simulations as essentially perfectly replacing data from “real” systems. The implications of this large difference in perception between advanced undergraduate/early graduate students and professionals are discussed. At present, suitable theoretical frameworks related to motivation do not afford satisfactory explanation for this observation.Work done at the Department of Electrical Engineering, University of Nebraska-Lincoln 相似文献

Using international data on child well-being and educational attainment, this article compares child well-being in the United States to member countries in the Organisation for Economic Co-operation and Development (OECD). Multiple measures of child well-being are analyzed, such as material well-being (including poverty, unemployment, and income inequality), child health and safety (birth weight, infant mortality, health care, and childcare), educational attainment, and family and peer relationships (including generational cleavages). Using Bronfenbrenner's ecological systems theory as an organizational framework, the impact and interrelatedness of these systems on educational attainment are examined, with parallels drawn between a nation's social policies, child well-being, and educational attainment. The author asserts that social policy in the United States is more comprehensive than is commonly believed, although the redistributive benefits of social policies are allocated much differently compared to OECD countries. Explanations for comparative differences in social policy include differences in political culture and political development as well as racial and class conflict. The author concludes that it is difficult to ignore the role of race and socioeconomic class in explaining differences in social welfare expenditures between the United States and European countries because the pattern of social welfare distribution (broadly conceived—including programs, tax breaks, and incentives) falls largely along racial and class lines. 相似文献
