This study examined the impact of computer simulation and supported science learning on a teacher’s understanding and conceptual
knowledge of current electricity. Pre/Post tests were used to measure the teachers’ concept attainment. Overall, there was
a significant and large knowledge difference effect from Pre to Post test. Two interesting interactions were observed during
the data analysis. The first was the difference between Elementary and Secondary teachers. Both groups had significant gains,
with large effect sizes, but the Elementary teachers (Pre-Mean = 3.70, Post-Mean = 7.51) started lower and ended higher exhibiting
a significantly larger gain than the Secondary teachers (Pre-Mean = 4.96, Post-Mean = 6.71). The second interaction was the
impact of gender. Both groups showed significant gains, with large effect sizes, but females (Pre-Mean = 3.90, Post-Mean = 7.21)
gained significantly more than males (Pre-Mean = 5.13, Post-Mean = 7.01). These results confirm that computer simulation supported
science learning can have a positive effect on concept attainment in teachers. 相似文献

Systemic action and learning in public services 总被引:1,自引:1,他引:0
Clare Rigg 《Action Learning: Research and Practice》2011,8(1):15-26
Complex, systemic issues continue to challenge public services without respect for organisational and professional boundaries. In practice, collaborative working with others who have differing professional cultural norms and systems confront members with the need to learn about each other's values, priorities and practices. This paper explores the potential of action learning for the development of systemic leadership capabilities within public services. Starting from core principles it is argued that action learning be seen not simply as a small group process for problem-solving or individual development, but as a collective process for inquiring into and taking action on projects and practices within their complex, multi-agent contexts. 相似文献

The use of "interactive storybooks" in the primary classroom may facilitate small group and individual reading with minimal teacher intervention. This small-scale study examines whether small groups of Year 5 pupils, without teacher supervision, progress linearly through an "interactive storybook" and whether such diversions as cued animations affect pupil comprehension. The study finds that more intensive choice of diversions affects some pupils' comprehension. 相似文献

This introductory essay reviews the key contributions of David Teece's landmark paper “Profiting from Innovation” published in research policy in 1986. It summarises the contributions of each of the papers in the special issue. It then offers some perspectives on the key themes emerging from these papers, and on the broader challenges facing researchers, strategists and policymakers in the field of technology innovation today. 相似文献

This paper presents an evolutionary framework for horizontal technology policies (HTPs) especially market-friendly ones involving project-based incentives (e.g. R&D project based grants rather than tax-based incentives to yearly expenditures on R&D). HTPs are a category of technological policies whose objective is to promote technological development per se, and associated management and organizational routines, irrespective of industrial branch or technological area. They are being increasingly adopted by both advanced countries and newly industrialized countries in response to the new opportunities and threats opened up by the technological revolution and by the processes of liberalization and globalization; and they complement the more specific and well-known selective and vertical policies aimed at individual sectors and technologies. The analysis is conducted within a learning-to-innovate framework with emphasis on collective, organizational learning; search; and market-building. The outcome is a technology policy cycle with distinct infant, growth, and mature phases. Proactive ‘generation’ of a critical mass of projects for efficient learning and diffusion of innovation routines becomes the aim of the infant phase; while the mature phase of the policy should focus on policy restructuring including drastic reductions in the support of routi projects and enhanced support of more complex types of innovation. The paper also emphasizes the importance of a neutrality component in incentives in the infant phase of increasing selectivity; and of building policy capabilities for efficient policy design and implementation. 相似文献

Income is not enough: incorporating material hardship into models of income associations with parenting and child development 总被引:2,自引:0,他引:2
Although research has clearly established that low family income has negative impacts on children's cognitive skills and social-emotional competence, less often is a family's experience of material hardship considered. Using the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (N=21,255), this study examined dual components of family income and material hardship along with parent mediators of stress, positive parenting, and investment as predictors of 6-year-old children's cognitive skills and social-emotional competence. Support was found for a model that identified unique parent-mediated paths from income to cognitive skills and from income and material hardship to social-emotional competence. The findings have implications for future study of family income and child development and for identification of promising targets for policy intervention. 相似文献
