To support teachers to implement Computer Science curricula into classrooms from the very first year of school, teachers, schools and organisations seek quality curriculum resources to support implementation and teacher professional development. Until now, many Computer Science resources and outreach initiatives have targeted K-12 school-age children, with the intention to engage children and increase interest, rather than to formally teach concepts and skills. What is the educational quality of existing Computer Science resources and to what extent are they suitable for classroom learning and teaching? In this paper, an assessment framework is presented to evaluate the quality of online Computer Science resources. Further, a semi-systematic review of available online Computer Science resources was conducted to evaluate resources available for classroom learning and teaching and to identify gaps in resource availability, using the Australian curriculum as a case study analysis. The findings reveal a predominance of quality resources, however, a number of critical gaps were identified. This paper provides recommendations and guidance for the development of new and supplementary resources and future research. 相似文献

Using micro-level public opinion data from the Pew Global Attitudes Project 2005, this study investigates the effect of educational attainment and income on support for democracy in five predominantly Muslim countries: Indonesia, Jordan, Lebanon, Pakistan, and Turkey. Holding all else constant and compared to not finishing primary education, this study finds that secondary education and higher education encourage support for democracy in Jordan, Lebanon and Pakistan. The results therefore suggest that support for democracy is a social benefit of education in Jordan, Lebanon, and Pakistan. Regarding income, the results indicate that relative to the poor, those belonging to middle-income groups are more supportive of democracy in Lebanon and Turkey. Curiously, there is no statistical relationship between belonging to the richest groups and supporting democracy. 相似文献

As university involvement in technology transfer and entrepreneurship has increased, concerns over the patenting and licensing of scientific discoveries have grown. This paper examines the effect that the licensing of academic patents has on journal citations to academic publications covering the same scientific research. We analyze data on invention disclosures, patents, and licenses from the University of California, a leading U.S. academic patenter and licensor, between 1997 and 2007. We also develop a novel “inventor-based” maximum-likelihood matching technique to automate and generalize Murray's (2002) “patent-paper pairs” methodology. We use this methodology to identify the scientific publications associated with University of California patents and licenses.Based on a “difference-in-differences” analysis, we find that within our sample of patented academic discoveries, citations to licensed patent-linked publications are higher in the three years after the license, although this difference is not statistically significant. We then disaggregate our sample into (a) patented discoveries that are likely to be used as “research tools” by other researchers (based on the presence of material transfer agreements (MTAs) that cover them) and (b) patented discoveries not covered by MTAs. Citations to publications linked to licensed patents in the latter subset (not covered by MTAs) are higher for publications linked to licensed patents, and this difference is statistically significant. In contrast, licensing of patented discoveries that are also research tools is associated with a reduction in citations to papers linked to these research advances, raising the possibility that licensing may restrict the flow of inputs to “follow-on” scientific research. 相似文献

This paper contributes to the debate on the energy efficiency paradox according to which consumers fail to adopt cost-effective, energy efficient technologies over less efficient technologies and therefore fail to reduce energy consumption. Both traditional and behavioural theories are used to investigate the decision-making process of residential consumers with empirical evidence based upon a specially designed quasi-experimental survey of 784 households on the decision to connect to a district-heating system, a more energy efficient alternative to individual heating systems. The results suggest an internal discount rate of around 36 per cent for homeowners, a signal that consumers undervalue future energy costs. We also find the household’s decision to be negatively affected by years of payback up to around 7–8 years. Our findings suggest that neglecting consumer inattention and heuristics can lead to biases which cast doubt on the existence of the energy efficiency paradox. We believe that these results help to explain why some consumers are unlikely to invest in energy efficient technology, particularly those on low incomes. 相似文献

Improving K-12 pedagogy via a Cloud designed for education 总被引:1,自引:0,他引:1

Cloud computing offers an opportunity to improve K-12 pedagogy with services tailored to teachers’ needs in individual classrooms. The Cloud can deliver services such as remote access to learning tools in a cost effective manner to school systems struggling with reductions in local and state funding. This article explores the distinct ways that a Cloud designed specifically for education can be applied to K-12 education's academic mission. It uses observations from a case study in North Carolina rural high schools using an educational Cloud called the Virtual Computing Lab to access dynamic geometry and algebra software. 相似文献

The reform of K-12 math and science education will require a national, multisector, bipartisan effort sustained for at least two decades. The effort will involve all levels of government, communities, local businesses, and schools. The federal government has a pivotal role to play. 相似文献
