In the 1970s and early 1980s, many Westerners wrote enthusiastically about science as practiced in socialist China. They applauded the mobilization of broad sectors of the population for science that truly "served the people." By the mid-1980s, revelations about the many horrors of the Cultural Revolution worked to discredit these early, optimistic accounts. At the same time, the post-Mao privileging of economic development over social revolution (which meshes well with dominant Western attitudes) now strongly colors almost all analyses of science in socialist China. This essay encourages historians to retrieve the largely discarded rosy accounts of earlier years. Such sources provide insight into the goals of historical actors and challenge us to recognize the specificity and contingency of our own values. Used in tandem with the later sources, they can help us achieve a critical understanding of science in both socialist China and our own historical context. 相似文献

Twelve focus groups were conducted with African-American and Latino youth (age 14-19) in Washington, DC to inform the development of a program to postpone sexual involvement among younger teens (age 12-14). The study's objectives were to uncover the prime motivators for early sexual involvement, examine attitudes towards pregnancy and contraception, explore peer and family influences on sexual decision-making, and identify the youth's preferred sources of information and advice on sexual matters. The data suggest that sex is a peer norm for these youth and generally begins by age 15 or before. The prime motivator for early sex among the young women appears to be social pressures from boyfriends, peers and even older siblings. In contrast, young men seem to be more motivated by physical desire, and draw a clear distinction between relationships that are exclusively sexual and those that are more serious and romantic. Early pregnancy was universally viewed as undesirable, but not always as a hindrance to one's future. While motivation to avoid pregnancy appears to be less pronounced among the African-American youth, potential barriers to contraceptive use seem prominent in both groups due to strong negative opinions about the safety and efficacy of various methods. Condoms are viewed as being appropriate for casual sexual encounters, but not for longer, more established relationships. Parents received mixed reviews as sources of information and guidance on sexual matters. Latino youth were more likely than African-Americans to view parents as being influential in their sexual decision-making, but appear less likely to rely on them for information and advice. All youth preferred clinics to schools for sex education and related services. Overall, these data signal the need for interventions that generate peer support for delaying sex and pregnancy, correct misinformation about contraceptives, and encourage frank, open discussions between youth and their parents or other caring adults. 相似文献

During the last 30?years, a new model of transnational educational governance including a specific knowledge production regime has been implemented. Its increasing national impact has caused enormous change within the German educational system. Particularly, the Organisation for Economic Co-operation and Developments statistical reports and benchmarking procedures like the Programme for International Student Assessment have challenged the German system, which has usually been remarkably resistant to reform, and have pushed it towards fast and deep transformation. Demonstrated with the case of Lower Saxony, one of Germany’s largest states, effects of massive political uncertainty in terms of educational principles, rules of governance as well as school practice can be identified. They result in an increasing authorization of so-called agents of change who offer both knowledge production and education service to policy and school practice. In the case of Lower Saxony, the Bertelsmann Foundation has been such an agent of change. It supported school reform while heavily promoting the adoption of a new self-evaluation instrument called self-evaluation in schools, which not only measures school quality, but creates a new certainty by generating knowledge about what is perceived as being real within school practice. In the end, there seems to be evidence that both the teacher profession and the classroom practice are made susceptible – not only to this new reality, but also to a new leadership. 相似文献

This study used data on 2,453 children aged 4–17 from the National Survey of Child and Adolescent Well‐Being and 5 analytic methods that adjust for selection factors to estimate the impact of out‐of‐home placement on children’s cognitive skills and behavior problems. Methods included ordinary least squares (OLS) regressions and residualized change, simple change, difference‐in‐difference, and fixed effects models. Models were estimated using the full sample and a matched sample generated by propensity scoring. Although results from the unmatched OLS and residualized change models suggested that out‐of‐home placement is associated with increased child behavior problems, estimates from models that more rigorously adjust for selection bias indicated that placement has little effect on children’s cognitive skills or behavior problems. 相似文献

ABSTRACTThe study presented in the paper has the following goals. The first is to review and compare teacher competence frameworks developed in Eastern (Chinese) and Western (German) contexts, exemplified for the domain of mathematics. Major similarities of the two contexts could be reconstructed in the conceptualization of teacher competence as a multidimensional construct comprising knowledge, teaching-related skills and beliefs. Distinct differences could be identified as well, with the Chinese frameworks including a wider range of teacher-competence facets and emphasizing more teaching-related competencies than the Western (German) frameworks. The second purpose is to adapt and validate a German framework of the measurement of mathematics teacher competence in a Chinese context. This adaptation and validation uses exemplarily mathematics teacher, in detail follow-up-studies of the international Teacher Education and Development Study: Learning to Teach Mathematics (TEDS-M). With the integration of a qualitative approach (e.g. elemental validity) and a quantitative approach (e.g. construct validity) to validate the framework, the results of both approaches suggest a satisfactory validity for the adaptation. Overall, the results point out that the examined teacher competence framework and its instruments can be used for comparative analyses in Germany and China. 相似文献

The basis of this study is a prognostic model derived from the theory of work and organizational psychology, from research about the selection of college students and from teaching and learning research. The model includes cognitive and psycho-motivational criteria for selecting students as well as objective and subjective indicators for study and job success. In a four-year longitudinal study with three measuring points, the prognostic validity of the selection criteria is tested (n?=?760). The basic hypotheses are that differences in the prognostic validity of the model for teacher training and subject-specific diploma students (both in the area of mathematics) exist, and that it is easier to predict study success than job success. Secondary school exit exam, classes in advanced mathematics, interest in mathematics, subject-specific study motivation and self-efficacy are the predictive indicators taken into account. Evaluative indicators for study success are study duration, intentions of dropping out, stress experiences, the results of university exit exam and students’ second state exam. Evaluative indicators for occupational success are the job status five years after graduation, job satisfaction and stress experiences. Bivariate correlations and regression analyses support the leading hypotheses. 相似文献
