从知识创造能力、知识获取能力、企业的创新能力等5个构成要素出发,构建创新能力评价指标体系。首先对八大经济区进行综合评价并对构成要素进行横向比较,然后对其2005—2012年的创新能力进行纵向分析。结果表明,东部和北部沿海的创新能力较其他区域有明显优势,南部沿海、东北地区、长江中游和西南地区分别居于第3—6位,黄河中游和西北地区较落后。近年来东北地区提升较快,而西南地区面临较快下滑。最后就提升各区域创新能力提出建议。  相似文献

Considerable effort has been made over the past decade to address the needs of learners in large urban districts through scaleable reform initiatives. We examine the effects of a multifaceted scaling reform that focuses on supporting standards based science teaching in urban middle schools. The effort was one component of a systemic reform effort in the Detroit Public Schools, and was centered on highly specified and developed project‐based inquiry science units supported by aligned professional development and learning technologies. Two cohorts of 7th and 8th graders that participated in the project units are compared with the remainder of the district population, using results from the high‐stakes state standardized test in science. Both the initial and scaled up cohorts show increases in science content understanding and process skills over their peers, and significantly higher pass rates on the statewide test. The relative gains occur up to a year and a half after participation in the curriculum, and show little attenuation with in the second cohort when scaling occurred and the number of teachers involved increased. The effect of participation in units at different grade levels is independent and cumulative, with higher levels of participation associated with similarly higher achievement scores. Examination of results by gender reveals that the curriculum effort succeeds in reducing the gender gap in achievement experienced by urban African‐American boys. These findings demonstrate that standards‐based, inquiry science curriculum can lead to standardized achievement test gains in historically underserved urban students, when the curriculum is highly specified, developed, and aligned with professional development and administrative support. © 2008 Wiley Periodicals, Inc.

This paper describes two studies that explore students' beliefs about critical and creative learning at two universities, and considers the implications of those beliefs in comparison to the universities' stated education goals. One is a mixed method study of students at a top university in Korea, and the second is a comparative study between the Korean university and a United States (US) university. The first study found that both high-achievers and the general population at a top Korean university perceived their critical and creative abilities as lower than their receptive learning abilities, and that higher achievers were neither more critical nor creative than lower achievers. The second study finds that the Korean university students, compared to US students, were more likely to rate their receptive learning ability as higher than their critical and creative learning abilities. Comparisons across year of higher education (HE) suggest that Korean students' perceptions did not significantly change with respect to year in school, while US students' perceptions of critical learning abilities significantly increased across school years. Results are discussed with respect to the impact of culture, epistemological beliefs, and HE instruction on critical and creative learning.  相似文献

This study examined relations among preschoolers' sibling-directed internal state language, perspective-taking abilities, and sibling-directed affective behaviors in 32 sibling dyads (aged 14 months and 3-4 years) during naturalistic home observations. Preschooler references about internal states (emotions, wants, abilities) were significantly more likely to be (a) about the toddler than the self, and (b) made in the mother's absence and during sibling conflict and play. Relative to poor perspective takers, skillful perspective takers (a) engaged in more instances of internal state discourse and (b) talked more frequently about both the toddler and themselves. Preschoolers engaging in high levels of positive affective behavior also spoke more frequently about internal states than children engaging in low levels of positive affective behavior. Discussion of results highlights the notion that internal state language may be one way of regulating sibling interaction and also a potential means for siblings to construct shared meanings about their world.  相似文献

This article explores the progression of one child’s literacy from 4 months to 38 months. The emergence of literate behaviour is interpreted in the light of current theories such as those of Halliday and Dyson. One of the most significant aspects of this emergence is shown to be interaction with others in authentic literacy activities, a feature which has a number of implications for teachers and researchers alike.  相似文献
