当探究性活动遭遇学生的功利性思维     

吴希成 《现代教育论丛》2011,(1)

学生参与探究性活动是探究性学习的外在表现形式。在根深蒂固的功利性思维驱使下,学生的探究性活动常常迷失核心目标指向。规范和激励学生的探究行为,既需要建立适合探究性活动的评价机制,也需要教育者的理性引导。  相似文献   

淡化“分数场”强化数学核心价值     

吴维煊 《现代教育论丛》2011,(4)

以分数为基本属性的分数聚集体——分数场,对教育的制约,越来越为人们所诟病,特别是以培养人的思维能力为教学目的的数学教学,若也以分数场为导向,师生们整日围着分数转,势必造成以能力培养为目的的数学教学变成以解题技术训练为目的的解题教学,教学目的的异化导致数学核心价值被遮蔽。淡化分数场,挖掘数学核心价值,在动态均衡中实现数学教育的优质发展,是学生长远发展对数学教学的迫切需要。  相似文献

Delay-dependent cluster synchronization of time-varying complex dynamical networks with noise via delayed pinning impulsive control     

Guang Ling  Xinzhi Liu  Ming-Feng Ge  Yonghong Wu 《Journal of The Franklin Institute》2021,358(6):3193-3214

This paper investigates the problem of cluster synchronization of complex dynamical networks with noise and time-varying delays by using a delayed pinning impulsive control scheme. Different from the traditional impulsive control schemes without the effects of input delays, it designs a pinning impulsive control scheme to successfully address the aforementioned problem subject to impulsive input delays. By employing a time-dependent Lyapunov function and the mathematical induction, some novel criteria are established to guarantee the cluster synchronization of the noisy complex networks, revealing the closed relationship between the synchronization performance and the related factors, including the impulsive input delays, the number of the pinned nodes, the frequency and strength of the impulsive control, and the noisy perturbations. Some numerical examples and computer simulations are presented to illustrate the effectiveness of the theoretical results.  相似文献   

Novel delay-partitioning approaches to stability analysis for uncertain Lur’e systems with time-varying delays     

Liang-Dong Guo  Sheng-Juan Huang  Li-Bing Wu 《Journal of The Franklin Institute》2021,358(7):3884-3900

This work deals with the problem of absolute stability analysis for a class of uncertain Lur’e systems with time-varying delays. Novel delay-partitioning approaches are presented, which are dividing the variation interval of the delay into three subintervals. Some new augment Lyapunov–Krasovskii functionals (LKFs) are defined on each of the obtained subintervals which can efficiently make use of the information of the delay and relate to the reciprocally convex combination technique and the Wirtinger-based integral inequality method. Several improved delay-dependent criteria are derived in terms of the linear matrix inequalities (LMIs). The merit of the proposed criteria lies in their less conservativeness and lower numerical complexity than relative literature. Two numerical examples are included to illustrate the effectiveness and the improvement of the proposed method.  相似文献   

Adaptive fuzzy output feedback fault-tolerant tracking control of switched uncertain nonlinear systems with sensor faults     

Yu Xiong  Yifei Wu  Shi Li  Zhengrong Xiang 《Journal of The Franklin Institute》2021,358(11):5771-5794

This paper investigates the adaptive fuzzy output feedback fault-tolerant tracking control problem for a class of switched uncertain nonlinear systems with unknown sensor faults. In this paper, since the sensor may suffer from an unknown constant loss scaling failure, only actual output can be used for feedback design. A failure factor is employed to represent the loss of effectiveness faults. Then, an adaptive estimation coefficient is introduced to estimate the failure factor, and a state observer based on the actual output is constructed to estimate the system states. Fuzzy logic systems are used to approximate the unknown nonlinear functions. Based on the Lyapunov function method and the backstepping technique, the proposed control scheme with average dwell time constraints can guarantee that all states of the closed-loop system are bounded and the tracking error can converge to a small neighborhood of zero. Finally, two simulation examples are given to illustrate the effectiveness of the proposed scheme.  相似文献
