我们需要什么样的现代学校制度

教育市场化不能成为建构现代学校制度的指导性原则,更不能将现代企业制度直接移植到现代学校制度中来。现代学校制度是一种"教育制度"而不是"经济制度",它所应关注的不是产权归属、产权明晰等经济学问题,而应是本真的教育问题,即学生的发展问题。现代学校制度包括核心制度和外围制度。建立现代学校制度要求转变政府的教育职能,落实学校的办学自主权。

试论康德艺术论中的"天才"思想

康德从先验的唯心主义哲学体系出发，在前人“天才”论的基础上，结合德国古典美学的时代特征，在艺术论中阐发了自己的“天才”思想，并用它沟通了自然与艺术。因此，理解其“天才”思想是理解其艺术论的关键。他的“天才”思想中既含有真理性的内容，也含有非科学的内容，对后代的哲学、美学产生深远的影响。     

基于LabVIEW的血糖浓度检测系统设计

目前人体血糖浓度检测方法往往需要取血测量,不仅费时费力,更加重了糖尿病患者痛苦。为减轻患者痛苦,实现人体血糖浓度快速检测,基于LabVIEW平台设计一种无创血糖浓度检测系统。该系统选用3个固定波长的LED光源生成近红外信号,采用USB-6008数据采集卡进行数据接收与处理,并通过软件设计完成人体血糖浓度检测与显示。实验结果表明,该检测系统可以有效测量、保存人体血糖浓度数据,并实现人体血糖浓度实时监测。     

An innovative consensus map-embedded collaborative learning system for ER diagram learning: sequential analysis of students’ learning achievements

Although computer-supported collaborative learning has been successfully applied in educational settings to improve group learning performance, most such systems still lack effective strategies for knowledge representation which could help reduce discussion time. In this study, concept mapping, already applied as a tool to help visualize and organize existing or newly learned knowledge, is incorporated to address this problem in a newly developed concept map and computer-supported collaborative learning system (CMCLS). It was designed as a quasi-experiment study and was carried out with 77 university students. The system was first used by the groups of students to illustrate their knowledge and achieve consensus during a learning activity, after which their performance and feelings of satisfaction with this innovative approach were evaluated. Patterns of learning within the proposed framework were explored. The learning behaviors, including the actions and interactions with peers of the participants during the learning activity were recorded. Finally, lag-sequential analysis was used to compare the interactions and the differences in the behavior patterns of the two groups, one using the newly developed CMCLS consensus map-embedded approach and a control group which did not use this approach. The results showed significant improvement in the learning achievement of students using the novel approach, as well as a higher degree of perceived usefulness and satisfaction. The novel consensus map-embedded approach was useful for knowledge construction and for assisting with integration of the team members’ results to produce the final ER diagram.     

主体性教育需把握的几个要点

教育是引导学生认识世界、认识自己、提高素质的过程 ,在本质上是对受教育者主体性的培育过程。因此 ,教师必须冲破传统教育观念的束缚 ,以学生为本 ,把主体性发展作为教学首要目标 ,通过培养学生的主体意识、主体能力和主体人格 ,发展和提高学生在教育活动中的能动性、自主性和创造性 ,建构学生丰富和全面的主体性 ,让学生真正成为“学习和发展的主人”。

Nonlinear dynamics analysis of a new autonomous chaotic system

In this paper,a new nonlinear autonomous system introduced by Chlouverakis and Sprott is studied further,to present very rich and complex nonlinear dynamical behaviors. Some basic dynamical properties are studied either analytically or nu-merically,such as Poincaré map,Lyapunov exponents and Lyapunov dimension. Based on this flow,a new almost-Hamilton chaotic system with very high Lyapunov dimensions is constructed and investigated. Two new nonlinear autonomous systems can be changed into one another by adding or omitting some constant coefficients.

Detection of gross errors using mixed integer optimization approach in process industry

A novel mixed integer linear programming （NMILP） model for detection of gross errors is presented in this paper. Yamamura et al.（1988） designed a model for detection of gross errors and data reconciliation based on Akaike information criterion （AIC）. But much computational cost is needed due to its combinational nature. A mixed integer linear programming （MILP） approach was performed to reduce the computational cost and enhance the robustness. But it loses the super performance of maximum likelihood estimation. To reduce the computational cost and have the merit of maximum likelihood estimation, the simultaneous data reconciliation method in an MILP framework is decomposed and replaced by an NMILP subproblem and a quadratic programming （QP） or a least squares estimation （LSE） subproblem. Simulation result of an industrial case shows the high efficiency of the method.
