直辖市“双一流”高校专利合作与知识流动研究

考察我国直辖市"双一流"高校的专利合作网络演化,为提升直辖市的科技创新合作效率,提升科技创新能力和城市创新综合竞争力,为技术创新主体选择技术合作伙伴、探究地区间、高校间知识流动提供经验、启示。本文运用合作强度Salton指数、专利引用、绝对合作频次等,以Patentics和国家知识产权局专利数据库为工具,获取直辖市"双一流"高校合作专利数据,构建高校间的专利合作矩阵,采用合作网络可视化分析,梳理直辖市"双一流"高校专利合作网络,揭示网络环境下高校科技创新和知识流动的特征及趋势,给出提升高校专利合作的建议。结果表明:直辖市"双一流"高校校际专利合作的强同城倾向,清华大学、北京大学、复旦大学是京沪两地的专利合作核心高校。清华大学、上海交通大学、天津大学专利申请量居前三,清华大学、上海交通大学的专利被引量居前,清华大学、上海交通大学、天津大学为专利合作的核心高校,对知识流动影响深刻。不足之处在于专利只能部分反映高校间的技术创新合作,合作申请只是技术合作的一部分,还包括科技论文合作和成果转化。

Teacher e-mail message strategies and students' willingness to communicate online

In light of the prevalent use of e-mail between teachers and students, researchers have highlighted the need to assess its uses and effects. Relying on the research and thinking of teacher immediacy and extra-class communication, we developed a scale that measures those e-mail message strategies that influence students' willingness to communicate online with their teachers. Next, we isolated those reasons that students use e-mail to interact with their teachers: (1) to clarify course material and procedures, (2) as a means of efficient communication, and (3) for personal/social reasons. Finally, we examined student characteristics such as gender and ethnicity, and history of e-mail use that may (or may not) influence their attitudes toward e-mail exchanges with teachers.

The Greek elementary “What Is Happening In this Class?” (G-EWIHIC): A three-phase multi-sample mixed-methods study

Students’ perceptions of their classroom psycho-social climate (CPSC) have been found to relate significantly to students’ learning outcomes. The What Is Happening In this Class? (WIHIC) being one of most prominent instruments in measuring these perceptions. The purpose of the present study was to thoroughly examine the structure of preadolescents’ perceptions of the CPSC, through an elaborate mixed-methods three-phase design, in the Greek elementary school context. The study included semi-structured interviews with students and teachers, and two large-scale administrations of the qualitatively adapted WIHIC version. Both qualitative and quantitative results supported the seven-subscale structure of the instrument and identified potential issues with the conceptual content of two of the subscales. Quantitative findings also supported the theoretical second-order factorial structure of the instrument, but with different subscale allocation. The advantages of mixed-methodology in the cross-cultural examination of student’s perceptions of the learning environment and implications for research are discussed.     

Does class-size reduction close the achievement gap? Evidence from TIMSS 2011

Policies about reducing class size have been implemented in the US and Europe in the past decades. Only a few studies have discussed the effects of class size at different levels of student achievement, and their findings have been mixed. We employ quantile regression analysis, coupled with instrumental variables, to examine the causal effects of class size on 4th-grade mathematics achievement at various quantiles. We use data from 14 European countries from the 2011 sample of the Trends in International Mathematics and Science Study (TIMSS). Overall, there are no systematic patterns of class-size effects across quantiles. Class-size effects are generally non-significant and uniform at different achievement levels, which suggests that in most European countries class-size reduction does not have an impact on student achievement and does not close the achievement gap. However, combined estimates across countries indicate that high achievers may benefit more from class-size reduction.
