适宜高校经济困难学生心理特征的资助体系建设

为使家庭经济困难学生的资助工作更有利于高校以人为本,全面发展的育人目标的实现,针对现行资助体系中物质资助远大于精神资助导致的对经济困难学生心理援助匮乏问题,基于问卷调查结果分析,结合资助工作实践,提出加大经济资助力度、改变奖助学金评比发放方式、完善贫困等级认定和改变资助工作方式等措施,将经济救助与心理援助有效结合,构建适宜高校家庭经济困难学生心理特征的资助体系。     

On the product of rotations

Using the elementary tools of matrix theory, we show that the product of two rotations in the three-dimensional Euclidean space is a rotation again. For this purpose, three types of rotation matrices are identified which are of simple structure. One of them is the identity matrix, and each of the other two types can be uniquely characterized by exactly one vector. The resulting products are investigated by using the basic properties of the vector cross product.

高校家庭经济困难学生认定指标体系的数学模型研究

为构建科学、合理和行之有效的高校家庭经济困难学生认定的量化指标体系,运用层次分析法的原理,先设计出一个多指标的层次结构图,建立数学模型,再计算出各项指标的权重分值,并对指标进行量化.采用分层抽样法,从武汉某高校家庭经济困难学生数据库中随机选取234名学生的资料,进行验证性认定,结果显示符合率达99.57%.该指标体系可靠、可行,具有推广价值和借鉴性.     

Exploring MLD in mathematics education: Ten years of research

Mathematical learning disabilities or difficulties (MLD) are an increasing source of educational inequalities. This article explores research about MLD in Mathematics Education over the past ten years. The methodology focuses on specific, validated keywords. These keywords are used to identify articles in leading journals in mathematics education. Our work makes several new contributions to the field of mathematics education, notably: a reusable methodology and keywords for a literature review; an exhaustive list of articles about MLD in leading mathematics education journals; a discussion of the definitions and features of MLD used in these articles; and a tool to classify research dealing with MLD (categories that characterize students with MLD). We also highlight some unexplored dimensions regarding MLD in Mathematics Education research.
