The effects of college students’ positive thinking,learning motivation and self-regulation through a self-reflection intervention in Taiwan

This quasi-experimental study examined the effects of a self-reflection intervention on college (college in this article refers to university-level education) students’ positive thinking, learning motivation and self-regulation in Taiwan. One hundred and two college students were selected to participate in an 18-week intervention forming the experimental group (EG) which emphasized providing main lecture, role-play, self-reflection activity, group discussion and group work. Another 179 college students from two other courses were selected as a comparison group. This study showed that supportive, resourced discussion with peers and instructor, self-reflection activities and assignment as a facilitative agent improved the EG students’ positive thinking, learning motivation and self-regulation. In addition, three structural equation models revealed that positive thinking had a strong and direct relation to Taiwanese college students’ pretest learning motivation (β?=?.85) and self-regulation (β?=?.77); learning motivation had a strong and direct relation to students’ pretest positive thinking (β?=?.86) and self-regulation (β?=?.81); and self-regulation had a strong and direct relation to students’ pretest positive thinking (β?=?.83) and learning motivation (β?=?.86). Instructional implications and research recommendations are discussed.

大学生心态状况调查及其积极心态培养对策研究

文章利用一般自我效能感量表和简易应对方式量表，对某校大学生作抽样调查，结果显示：不同性别和专业的大学生在自我效能感和应对方式上无显著差异；大学生自我效能感的来源存在偏差，主导性的应对方式也有错位。这表明当代大学生的心态并非都是积极的。因此，高校思想政治工作者要高度关注和研究大学生的心态问题。要培养大学生基于能力的自我效能感，要形成以行动为主导的应对方式，要建立起积极心态培训机制。

一类三阶n点边值问题的正解的存在性

令ai≥0,i=1,…,m-3且am-2>0.再令ξi满足0<ξ1<ξ2<…<ξm-2<1且∑m-2i=1aiξi<1.我们研究下面边值问题正解的存在性u?(t)+a(t)f(t)=0,t∈(0,1),u(0)=u′(0)=0,u′(1)=∑m-2i=1aiu′(ξi)其中a(t)∈C([0,1],[0,∞]),f(t)∈C([0,1],[0,∞]).通过锥上的不动点定理证明了在f满足超线性或次线性条件下,上述问题至少存在一个正解.     

Vagueness in Teachers' Spoken Language

Politeness symbolizes human civilization,and is one of conduct codes of human beings.As a social activity,language use is subject to this code as well.Pragmatic vagueness is a common phenomenon in spoken discourse.Furthermore,it is an important strategy widely used in teachers’ spoken language.Based on the politeness principle,this thesis explores the pragmatic vagueness by analyzing teachers’ spoken discourse.Employing pragmatic vagueness in teacher’s spoken language can smooth the relationship between teachers and students,and help teachers gain foremost effect on the education to their students.     

消费主义与高校课程的文化际遇

消费主义进入高校,对高校课程的影响是全面而深远的。消费主义把课程仅仅作为一个消费的对象,课程被＂物化＂了,学生对课程的参与度降低,而且课程扁平化,师生关系异化。其积极影响有：课程效率提升与产业发展的距离拉近;消极影响有：课程中易出现短期行为,学生对课程体验的消解,以及＂单面人＂的出现和课程批判功能的消失。
