Teacher support,instructional practices,student motivation,and mathematics achievement in high school

The authors examined the relationships among teacher classroom practices, student motivation, and mathematics achievement in high school. The data for this study was drawn from the base-year data of High School Longitudinal Study of 2009. Structural equation modeling method was used to estimate the relationships among variables. The results indicate that conceptual teaching positively affected student mathematics achievement, whereas procedural emphasis in mathematics instruction had a negative effect. Teacher support influenced student mathematics achievement indirectly through students' mathematics self-efficacy, and also influenced students' interest in mathematics courses. Finally, students with higher levels of family socioeconomic status and prior achievement were more likely to have teachers who use conceptual teaching strategies. Students with higher prior achievement were also more likely to perceive higher levels of teacher support. The findings have theoretical and practical implications.     

Empirical Study of the Role of Government Support and Success Factors in Industry-University-Institute Cooperation

Abstract

Empirical research methods were used to study the state of industry-university-institute collaboration in China and the factors influencing the results of cooperation between members of technological innovation alliances, from the dual perspectives of enterprises and universities/research institutes On the basis of questionnaire surveys of 100 universities/research institutes and 100 enterprises across the country, through factor analysis, correlation analysis, regression analysis, and other methods, we conducted a thorough study of the impact of success factors and government support on the results of cooperation; we found that the format of an alliance has a significant promotional effect on the results of industry-university-institute cooperation, but universities/research institutes have not given this sufficient attention. Among the success factors for industry-university-institute cooperation, enterprises give equal weight to the factors of “ability” and “mechanisms,” while universities/research institutes emphasize “ability.” The government must strengthen policy support for enterprises and guiding support for universities/research institutes.

教师合作：教师发展的一个重要路径

20世纪80年代以来，教师合作作为教师发展的一种方式获得广泛的关注，成为国际教师教育研究领域中一大热点问题。本文认为，所谓教师合作，就是教师们为了改善学校教育实践，以自愿、平等的方式就共同感兴趣的问题，共同探讨解决的办法，从而形成的一种批判性互动关系；教师合作有助于激发与强化教师发展意愿、提高教师个体反思能力、促进学校组织学习。     

浅议信息技术对综合课程实施的支持作用

A New Autonomy-Supportive Way of Teaching That Increases Conceptual Learning: Teaching in Students' Preferred Ways

We tested the educational utility of “teaching in students' preferred ways” as a new autonomy-supportive way of teaching to enhance students' autonomy and conceptual learning. A pilot test first differentiated preferred versus nonpreferred ways of teaching. In the main study, a hired teacher who was blind to the purpose of the study taught 63 college-age participants in small groups the same 48-minute lesson in one of these two different ways, and we assessed participants' perceived autonomy support, autonomy-need satisfaction, engagement (self-report and rater scored), and conceptual learning (self-report and rater scored). Multilevel analyses showed that participants randomly assigned to receive a preferred way of teaching perceived the teacher as more autonomy supportive and showed significantly greater autonomy-need satisfaction, engagement, and conceptual learning. Mediation analyses using multilevel modeling for clustered data showed that this way of teaching enhanced conceptual learning because it first increased students' autonomy. We conclude that “teaching in students' preferred ways” represents a way of teaching that increases students' autonomy, engagement, and conceptual learning.     

基于几何特征和支持向量机的人脸检测

针对人脸检测中的非线性和降维问题提出了一种有效的人脸检测方法。首先基于人脸的肤色和几何特征．通过局部自适应门限方法提取图象边缘，用几何规则和颜色特征筛选出候选眼睛块。然后采用改进的四边界sobel算子对眼睛精确定位。最后使用训练好的支撑向量机来验证。该方法可以实现多尺度多角度的彩色图像中的正面人脸检测，实验结果令人满意。
