Higher education institutions are trying to provide more flexibility and individualization, which is mainly realized through the use of new technologies and implemented in online or blended learning designs. This systematic review aims to investigate the impact of replacing classroom time with an online learning environment. The meta-analysis (k = 21 effect sizes) applied strict inclusion criteria concerning research design, measurement of learning outcomes and implementation of blended learning. The estimated effect size (Hedge's g) was positive, although not significantly different from zero and the confidence interval [-0.13, 0.25], suggesting that overall differences between blended and conventional classroom learning are small, and, at best, very small negative or moderate positive effects are plausible. This means that despite a reduction in classroom time between 30 and 79 per cent, equivalent learning outcomes were found. Consequently, blended learning with reduced classroom time is not systematically more or less effective than conventional classroom learning. 相似文献

This article reports on a UK study identifying innovative practice in the use of ICT to link home and school and its potential for enhancing learning. It is set in the context of recent political tensions and the mismatch between ICT use in the home and traditional educational systems. The theoretical framework draws upon curriculum theories and reviews what is already known about home use of ICT. A survey was administered to schools identified for innovative models of practice in both teaching and learning, and management and administration. From the 115 responses, eight contrasting case-study schools were selected. Three exemplars highlight a shift in practices: a move towards self-directed learning; greater flexibility and autonomy for students; and improved communication between home and school. We argue that technology could support a broader access to the curriculum, but that policy-makers should be aware of the digital divide issues. Young people's home use of technology suggests a rich experience involving exploratory activities, access to knowledge and the opportunity to publish their views. Curriculum reform is essential in order to maximize the potential of technology. It demands a shift away from current curriculum and pedagogy towards critical thinking and knowledge construction. 相似文献

大多数图书馆图书的借阅期限是以读者类型为依据所确定的,这种借阅制度忽略了图书有效性所带来的读者需求的变化,不能充分利用图书的效用。本文结合文献老化理论,提出了以图书时效性为依据的弹性借阅制度,这种新的借阅制度可以充分利用图书的时效性,满足尽可能多的读者需求,真正实现书尽其用的图书馆思想。 相似文献

The main idea of the original parallel distributed compensation (PDC) method is to partition the dynamics of a nonlinear system into a number of linear subsystems, design a number of state feedback gains for each linear subsystem, and finally generate the overall state feedback gain by fuzzy blending of such gains. A new modification to the original PDC method is proposed here, so that, besides the stability issue, the closed-loop performance of the system can be considered at the design stage. For this purpose, the state feedback gains are not considered constant through the linearized subsystems, rather, based on some prescribed performance criteria, several feedback gains are associated to every subsystem, and the final gain for every subsystem is obtained by fuzzy blending of such gains. The advantage is that, for example, a faster response can be obtained, for a given bound on the control input. Asymptotic stability of the closed loop system is also guaranteed by using the Lyapunov method. To illustrate the effectiveness of the new method, control of a flexible joint robot (FJR) is investigated and superiority of the designed controller over other existing methods is demonstrated. 相似文献

The purpose of this study was to build a flexible mechanical system with a hydrostatic skeleton. The main components of this system are two type flexible bags. One is a structural bag with constant inner pressure. The other is an actuator bag with controlled inner pressure. To design the system, it was necessary to estimate both structural deformation and driving force. Nu- merical analysis of flexible bags, however, is difficult because of large nonlinear deformation. This study analyzed structural strength and driving force of flexible bags with the nonlinear finite element analysis （FEA） software ABAQUS. The stress con- centration dependency on the bag shape is described and the driving force is calculated to include the large deformation. From the analytical results, this study derives an empirical equation of driving force. The validity of the equation was confirmed by condition-changed analyses and experimental results. 相似文献

《故事新编》文体文类的复杂性,与鲁迅自觉追求荒诞感的营造是分不开的。其荒诞感主要通过古今杂糅的时空塑造,否定式的小说情节、结构模式,“油滑”的笔法表现出来,我们从《起死》篇的个案分析中,可以见出荒诞书写的深层意蕴：对庄子“无是非观”思想的解构式审视;指刺现实并加以批判;对启蒙的反省和追问。 相似文献
