The level test and cultivation reaseatch on mathematics reading ability of junior students—Taking X School for Example

阅读是与我们生活息息相关的一项重要活动。随着现代信息技术的不断发展，阅读能力的培养不再仅仅是文科的专项内容。对于数学的学习大多数人认为只要记住公式，定理。通过反复的练习，甚至题海战术，就能够把数学学好。社会在不断地发展，课程标准也在不断地变化，对于数学的学习不再是传统意义上的运算技能。学生只有具备数学阅读的能力，才能够从现实问题中抽象出数学问题，进而用所学的数学方法来分析问题，解决问题。鉴于数学阅读的重要性，本研究以学生的阅读能力水平检测及阅读能力的培养方法探索做为研究内容，以我校初一年的学生为主要研究对象，运用问卷调查，试题检测，实验对照等研究方法，对学生进行阅读现状的调查。采用问卷调查与试...In our lives,reading is very important.

EMBA背景的董事长更擅长投资吗?——基于中国上市公司投资效率视角的检验

本文以2007—2015年沪深A股非金融类上市公司为研究对象,实证检验董事长的EMBA背景和所属企业投资效率间的关系。研究发现:(1)相较于其他企业,拥有EMBA背景的董事长所属企业的投资不足现象明显更少,而投资过度水平却更高,该结论在采用工具变量法、Heckman两阶段模型、倾向得分匹配法和安慰剂检验等控制可能的内生性问题后依然成立。(2)分样本检验发现,董事长EMBA背景对企业投资效率的影响仅存在于缺乏商科知识储备、社会关系网络较弱的董事长所属企业,说明EMBA背景通过改善董事长的知识结构、拓宽社会关系网络作用于企业的投资效率。(3)进一步研究发现,拥有"名校"EMBA背景的董事长更擅长投资决策,其所属企业的投资不足和投资过度现象相对不明显。本文丰富了高层梯队理论的研究内涵,为教育部门制定相关政策及市场对EMBA项目价值的正确认识提供了实证支持。国家自然科学基金面上项目(71572158;71372071

Achieving Efficient Teacher Talk: A Reflective Analysis of Teacher-student Class Communication

In recent years, there has been an increase in the number of studies on “teacher talk” used in TCSL classrooms. Many of these studies are focused on language interactions between the teacher and the students as well as on the individual functions of “the teachers’ classroom talk.” This article examines the current status of, and problems associated with, teachers’ instructional language, i.e., teacher talk. Based on transcripts of audio recordings of teachers’ instructional language, this study analyzes problems ranging from inaccurate to excessive words in the instructional language and the causes of these problems. This article also validates the study findings by analyzing textual data on teachers’ reflections, and also proposes specific solutions such as simplifying vocabulary and grammar of the instructional language, using auxiliary methods, establishing typical linguistic contexts, and implementing graphics and charts to organize thoughts. Finally, fundamental strategies to achieve “efficient instruction” are made that teachers intentionally enhance their Chinese language competence and teaching abilities, and educational institutions place sufficient emphasis on teacher training and instructional guidance and implement best practices
