模态试验分析在教学中的应用和实践

模态试验分析是了解结构动态特性的有效手段.通过模态试验,可以计算出结构的固有频率、模态振型、阻尼比等参数,为结构设计与优化打下坚实的基础.在实验教学中,通过对模态试验的基本原理、主要步骤和试验中注意事项的介绍和分析,可以指导学生完成模态实验,加深学生对理论知识的理解和掌握,提高学生的动手能力、独立思考能力和分析解决问题的能力.     

反思性教学在Java程序设计实验教学中的应用研究

反思性教学是反思在教学活动中的运用和体现,是指在教学实践过程中教师对自身的教学行为不断进行反思的一种行为.在Java程序设计实验教学中,教师应当掌握反思性教学理论,在实验教学前、实验教学中、实验教学后不断反思自己的教学行为,提高教学能力.

以社会主义核心价值体系引领大学校园社会思潮的探索

伴随着中国共产党建党九十周年取得了伟大的成就,各种社会思潮也进入当代大学校园,而且表现出空前的多样性、多变性、复杂性。对此,我们要坚持用马克思主义基本原理进行客观辩证的分析,不能简单地予以否定;要在坚持尊重差异、包容多样的基础上,旗帜鲜明地做到坚持大学校园文化指导思想的一元化,用社会主义核心价值体系引领当代大学校园中多元化的社会思潮,最大限度地形成大学校园思想共识,做到贴近学生、贴近校园、贴近生活。     

Resistance partial factor and reliability of cast ball-and-socket support joint

Considering the uncertainty of material performance, geometric characteristic and analysis method, the analysis of statistical parameters of the resistance of cast ball-and-socket support joints and the reliability analysis are carried out by JC method (improved first-order second-moment method) based on the relevant experimental data. Results show that the resistance partial factor of the joint increases with the increase of the reliability index. The resistance partial factors are suggested corresponding to the reliability index under different load combinations. Moreover, the suggested resistance partial factor is adopted in reliability design, and it is found that the reliability index of the joint is larger than the target reliability index. The optimal load combination is the one in which live load plays an important control role. Finally, based on the suggested resistance partial factors, the reliability analysis of cast ball-and-socket support joints of a project is conducted.     

基于VAR模型通货膨胀影响因素的实证分析

分析了十年我国两次比较严重的通货膨胀的成因,使用2001年1月—2010年9月的季度数据,在构建稳定的VAR模型基础上,通过建立协整方程,运用格兰杰因果检验以及脉冲响应函数的方法,对其进行分析。结果表明：经济增长、广义货币供给量、房地产销售价格指数、外汇储备与CPI之间存在长期的协整关系;长期内以房地产为代表的资产价格对CPI的冲击较大,短期内外汇储备推高CPI的效果最为显著。     

高校教学团队建设评价标准初探

高校教学团队的建设是高等院校提高教学质量的重要措施之一,也是师资队伍建设的重要环节。但是目前,关于高校教学团队的评价标准机制还不很完善。通过对现有高校教学团队建设的分析,旨从团队组成、团队带头人、教学工作、教学研究、教材建设、运行和管理机制6个方面以量的形式给出了高校优秀教学团队建设相应的评价标准。即团队组建具有合理性,团队成员具有较高的学术和科研水平,管理运行机制具有示范性。     

Understanding students’ engagement in MOOCs: An integration of self-determination theory and theory of relationship quality

Although Massive Open Online Courses (MOOCs) attract millions of people to enroll in their courses, the completion rate for most courses is very low. A majority of MOOCs students are not fully engaged in MOOCs, thus leading them to quit in the early stage of the courses. Therefore, it is important to investigate students’ engagement in MOOCs. Drawing on self-determination theory and the theory of relationship quality, this study proposes a model that conceptualizes the MOOCs engagement as consisting of psychological engagement and behavioral engagement and explores the antecedents of students’ engagement in MOOCs. The research model is tested using data collected from 374 students of Chinese University MOOC. The results show that fulfillment of three basic psychological needs for autonomy, competence and relatedness have significant positive effects on intrinsic motivation, increasing students’ psychological engagement in MOOCs. Relationship quality significantly predicts students’ psychological engagement, and psychological engagement promotes behavioral engagement in MOOCs. Implications for research and practice as well as limitations of this study are discussed finally.     

Building a just world: the effects of service-learning on social justice beliefs of Chinese college students

This study aimed to examine the effects of different service experiences on the social justice beliefs of 60 Chinese college students with mixed methods. The quantitative results indicated that the participants in two service groups (i.e. for at-risk adolescents and adolescents with cerebral palsy) demonstrated a more significant promotion of social justice beliefs than their peers in non-service group. A qualitative analysis provided evidence of the mechanism underlying service-learning, as well as different service experiences affecting on students’ social justice beliefs. Finally, the implications for implementing service-learning and realizing social justice goals in China were discussed.
