Research on Compatible Mode of Self-directed Learning and Cooperative Learning in Blended Teaching of Basic English Course

In the information age,blended teaching,no matter online or offline,has become the mainstream of college teaching reform.In this teaching model,self-directed learning and cooperative learning are the two main learning approaches.On the online teaching platform,students mainly learn knowledge-based content by self-directed learning,while practising their language skills by cooperative learning in flipped classroom activities.On one hand,it advocates student-centered strategy so as to improve students autonomous learning ability;on the other hand,teachers serve as a guide to organize the classroom activities;meanwhile,they give timely feedback to students in order to promote students’learning ability.In blended teaching model,this mutually compatible and reinforcing model of self-directed learning and cooperative learning is undoubtedly helpful to improve the teaching efficiency.

Power allocation and mode selection methods for cooperative communication in the rectangular tunnel

For the multipath fading on electromagnetic waves of wireless communication in the confined areas,the rectangular tunnel cooperative communication system was established based on the multimode channel model and the channel capacity formula derivation was obtained.On the optimal criterion of the channel capacity,the power allocation methods of both amplifying and forwarding(AF) and decoding and forwarding(DF) cooperative communication systems were proposed in the limitation of the total power to maximize the channel capacity.The mode selection methods of single input single output(SISO) and single input multiple output(SIMO) models in the rectangular tunnel,through which the higher channel capacity can be obtained,were put forward as well.The theoretical analysis and simulation comparison show that,channel capacity of the wireless communication system in the rectangular tunnel can be effectively enhanced through the cooperative technology;channel capacity of the rectangular tunnel under complicated conditions is maximized through the proposed power allocation methods,and the optimal cooperative mode of the channel capacity can be chosen according to the cooperative mode selection methods given in the paper.

Research on the autonomous cooperative teaching mode in higher Vocational colleges

The traditional teaching mode belittles practice and emphasis theory, regardless of the students’ enthusiasm and interest in learning. However, the educational objective of the higher vocational colleges is to cultivate practical talents. Therefore, the reformation and innovation of the higher vocational education teaching mode must be carried out. This research analyses the effect of autonomous cooperative teaching mode in higher vocational colleges. The reformation of teaching mode consists of the following three parts first, the autonomous cooperative teaching needs to improve the existing education system, to lay the foundation for the work of education. Secondly, to strengthen the capacity of building and promote the full implementation of the project is essential. Finally, strengthen the construction of educational resources, and enrich the connotation of the carrier. Proved by practice, the independent collaborative teaching mode can not only improve the learning atmosphere, but also improve student achievement, but also do well to students’ all-round development and enhance their comprehensive quality. It is worthwhile to promote and implement this mode in higher education institutions.

Multiple mode cooperation based software engineering talents training

The main problems of the traditional software talent training are that the knowledge learned is out of touch of the industry,weak ability to solve complex engineering problems and the comprehensive quality cannot meet the requirements of enterprises.Taking the course of digital image processing as an example,this paper analyzes the key steps in the training process in details,and proposes a multiple mode collaborative based software engineering talent training mechanism,which brings the key subjects of teaching materials,teachers,students,enterprises,subjects into a unified training mechanism,so as to provide a new ideas for software talent teaching.
