In this method, an improved Comm Net network based on a communication mechanism is introduced into a deep reinforcement learning algorithm to solve the multi-agent problem. A layer of gated recurrent unit(GRU) is added to the actor-network structure to remember historical environmental states. Subsequently,another GRU is designed as a communication channel in the Comm Net core network layer to refine communication information between UAVs. Finally, the simulation results of the algorithm in two sets of scenarios are given, and the results show that the method has good effectiveness and applicability.展开更多

Therefore, listening is an important skill of English learning and listening training is an indispensible part of language learning. However, listening can easily be affected by anxiety. Anxiety, an obvious psychological phenomenon in listening and speaking, has negative effect on language input, process and output. Although anxiety has negative influence on English listening, it can be overcome by Cooperative Learning (CL). CL can reduce anxiety, improve communication ability and strengthen learners' confidence, etc.展开更多

Cooperative learning is recognized as a well-known student-centered teaching method in the mainstream educational approaches ranging from kindergarten to tertiary education in other parts of the world. However, it is still not seen as an important method to use in China today. This paper briefly reviews and summarizes the major achievements as well as setbacks of FLT research in the past 60 years since the founding of the People's Republic of China. It also addresses some important issues in the history of the development and the prospect of FLT, and the career development of FL teachers in China. Moreover, it presents argumentations in the remarkable exploratory process of educational theories of FLT with Chinese characteristics. It concludes that more and more Chinese FL teachers will implement cooperative learning in their classroom activities and enrich the connotations of this approach.展开更多

An important part of the paper is on the definitions of CL, second language acquisition(SLA) and relative literature by scholars or educators home and abroad, such as historical and contemporary views of CL, its development and application in a variety of classrooms, esp. in multi-lingual settings, in UMA. It also puts much emphasis on sociocultural aspects of CL. Besides, this paper compares the application of CL with that in SWUST,one public university in Southwest China. In views of current problems and awkward situations in the application of CL, the paper argues that the qualified teachers and quality monitoring systems are the two major decisive factors that affect the achievement of CL in Spanish institutions. This paper also analyzes the main characteristics of the classroom teaching in Mediterranean European Cultural Settings. Thus, the paper suggests that CL may be one of the most efficient approaches to improving the quality of education in UMA. Finally, the paper concludes with recommendations and suggestions that Spanish institutions train more wellqualified teachers to meet the increasing demand of CL approach in multi-contextual or multi-lingual settings.展开更多
