义务教育学校现代化办学标准的价值转向——兼论省级义务教育学校现代化办学标准的研制     

孙向阳 《教育发展研究》2011,(24)

现代化的办学标准是推进教育现代化的重要举措与保障,均衡发展是制定义务教育现代化办学标准的理论基础与核心思想。现代化办学标准的价值取向应当实现:从强调效率向追求均衡及公平的转向、从单项性办学标准向综合性办学标准的转向、从初步均衡向优质均衡的转向、从单一质量观向全面质量观的转向、从政府管学校向政府办学校的转向、从学校的被动发展向主动发展的转向。这种价值观指导下的省级现代化办学标准应当设有硬件建设、师资队伍、经费保障、办学行为、教育质量、文化建设六大领域四十五个现代化的指标体系。  相似文献

Ain’t nobody got time for dad? Racial-ethnic disproportionalities in child welfare casework practice with nonresident fathers     

《Child abuse & neglect》2019

BackgroundGiven fathers’ potential role in bringing about desired child welfare case outcomes, researchers have begun to identify factors that impact agency efforts to identify and involve fathers. Racial-ethnic inequality and bias are not among factors studied, despite longstanding evidence that racial-ethnic minority children make up a disproportionate share of the child welfare population.ObjectiveWe set out to identify racial-ethnic patterns in initial casework activity with nonresident fathers and explore whether select factors explain racial-ethnic differentials.Participants and SettingCaseworkers of 1,754 children in foster care in four U.S. states were surveyed.MethodsBivariate and multivariate logistic regression models were used to identify factors associated with whether agencies identified, located, and contacted nonresident fathers.ResultsAgencies were less likely to identify nonresident fathers of Black, Latinx, and Multiracial children, relative to those of White children. Among fathers whom agencies identified, Black and Latinx fathers were less likely to be located. Among fathers whom agencies located, Black and Latinx fathers were less likely to be contacted. Whereas greater rates of international mobility among Latinx fathers explained agencies’ disproportionately low rates of contact, no other factor explained racial-ethnic differentials.ConclusionWe find evidence of historical racial-ethnic disproportionalities across the three initial stages of casework practice with nonresident fathers in U.S. child welfare systems. Though more recent data are needed, this research suggests that racial-ethnic minority foster children are more likely than White foster children to be denied the benefits of agency-father contact, whether due to societal or systemic racial inequalities.  相似文献

The exclusive language of science? Comparing knowledge gains and motivation in English-bilingual biology lessons between non-selected and preselected classes     

Nina Meyerhöffer  Daniel C. Dreesmann 《International Journal of Science Education》2019,41(1):1-20

The dominant role of English as the global language of science entails a requirement for science teachers to equip their non-native English-speaking students with receptive and productive language skills for communication in scientific contexts. Although science courses with English elements are part of some schools’ bilingual programmes, they are usually not available to a wider student audience, but are restricted to high achieving or highly motivated students. The present study was to test whether a newly developed biology content and language integrated learning (CLIL) unit could also benefit standard ninth grade classes. The learning gains and motivation of bilingually inexperienced students were compared to those of a preselected group and a comparison group that had been taught solely in their native language. All participating classes achieved similar gains in content knowledge, and the standard students rated their motivation for bilingual science lessons as positive, albeit not as high as the preselected group. We thus provide evidence against concerns that teaching non-selected students bilingually might lead to deficits in content knowledge acquisition. Following this, we conclude that scientific English should be a part of standard science lessons regardless of specific school programmes.  相似文献   

Demystifying blockchain: A critical analysis of challenges,applications and opportunities     

《International Journal of Information Management》2020

The blockchain is considered to be the potential driver of the digital economy. The Blockchain technology outweighs the challenges associated with the traditional transaction business governed and regulated by the third trusted party. There is a growth in the interest among the researchers, the industry, and the academia to study and leverage the potential of Blockchain. Blockchain provides a decentralized and distributed public ledger for all the participating parties. Though it seems that blockchain is a viable choice and solution for all the centralized governed and regulated transactions (in digital online space), it has potential challenges that need to be resolved; opportunities to be explored, and applications to be studied. This paper utilizes a systematic literature review to study several research endeavors made in the domain of blockchain. To further research on blockchain adoption, the paper theoretically constructs an integrated framework of the blockchain innovation adoption process in an organization considering organizational and user acceptance perspectives. This would facilitate its widespread adoption, thereby achieving sustained leadership solutions. The paper offers 23 propositions to information systems (IS)/information management (IM) scholars with respect to innovation characteristics, organizational characteristics, environmental characteristics, and user acceptance characteristics. Further, the paper explores several areas of future research and directions that can provide deep insights for overcoming challenges and for the adoption of blockchain technology.  相似文献
