The flexible and convenient mobile learning conforms to the characteristics of adult students, which has attracted the attention of adult educators. In view of the fact that there are more theoretical studies and less empirical studies, this study, based on the open mode, adopts the experimental method to conduct an empirical study on mobile learning of Public English course in Open University of China for two years. The results show that the test marks of mobile learning teaching class are significantly better than those of conventional teaching class. This study expands the sample level of mobile learning, and provides an empirical basis for mobile learning research in adult education.展开更多

From the perspective of front-line teachers and based on the OPEN mode of English, this study takes Humanistic English 3, a series of workplace English textbooks, as an example, and proposes that online teaching design should pay attention to online teaching strategy design, learning resources and media design, online learning task design and online learning evaluation design, so as to provide reference for online teaching design of Public English.展开更多

The lead introduces mode coupling with bound states in the cavity which contributes to Fano resonant line shapes in conductance. By examining the resonant states in the cavity, the effects of state mixing and annular probability distribution of wave function due to the presence of leads are found. The results have been compared with the transport properties of other systems. The finite leads result in two effects, i.e. the evanescent mode contribution and additional oscillations, to the conductance.展开更多
