小学数学教学中平面图形面积的教学策略

小学阶段学习的数学平面图形主要包括长方形、正方形、三角形、平行四边形和圆等,学生应该掌握这些基本图形的面积公式,并能运用公式来计算平面图形的面积。其中,数据建模和多媒体技术是很重要的教学工具,它能够很大程度地调动学生的学习热情,理清学生的思绪,提高其学习效率。因此,教师在进行平面图形教学时,要加强教学工具的应用,构建小学数学的高效课堂,培养学生良好的思维模式,促进学生的全面发展。

Automated Design and Visualization System of a House Foundation from Blocks

This article analyzes creation methods of automated design system, presents design system of a house foundation from blocks. The creation methods of automated design system of a house foundation from blocks are discovered with Unified Modeling Language. Analyzed objects-classes： block, specification, model. Graphical system can design foundation, form specification of objects and create 3D model of house foundation. There are several types and different dimensions of concrete blocks. The program optimally arranges selected blocks so that monolithic parts will be minimal volume. Program selects a house foundation blocks from database by using ActiveX Data Objects technology, which by programming method connects drawing and database. Drawing＇s graphical objects have additional data from which exchange of data between graphical system and database is executed. Visualization system and example of house foundation from blocks project with specifications is presented. Creation problems of automated design system are discussed and conclusions are made.

Innovate Triple Constraints Model for Better Construction Project Results

The continuous changing impacts appeared in all solution understanding approaches in the projects management field （especially in the construction field of work） by adopting dynamic solution paths. The paper will define what argue to be a better relational model for project management constraints （time, cost and scope）. This new model will increase the success factors of any complex program/project. This is a qualitative research adopting a new avenue of investigation by following different approach of attributing project activities with social phenomena, and supporting phenomenon with field of observations rather than mathematical method by emerging solution from human, and ants＇ colonies successful practices. The results will show the correct approach of relation between the triple constraints considering the relation as multi agents system having specified communication channels based on agents locations. Information will be transferred between agents, and action would be taken based on constraint agents locations in the project structure allowing immediate changes abilities in order to overcome issues of over budget, behind schedule and additional scope impact. This is complex adaptive system having self organized technique, and cybernetic control. Resulted model can be used for improving existing project management methodologies.

The Probe into the Methods of Implementing General Education in Application-oriented Civilian-run Colleges and Universities

This paper conducts the probe into the methods of implementing the general education in application-oriented civilian-run colleges and universities. As the basic education for the construction of high-quality teachers more and more urgent, how to make application-oriented colleges and universities teacher education in the personnel training level and training mode to meet the basic education development needs. Therefore, accomplishes the counted by the 100 million high quality worker diligently, ten million counts the professional personnel and a large quantities of best pick of the crop innovation talented person, specially raises the considerable amount to stress in the practical work department on the solution actual problem high level. Compared with the state-of-the-art core applications, this paper’s idea is novel and effective.
