Assuming the dual roles of a teacher and a researcher, the writer of this paper has implemented three models of classroom instructions for the Viewing, Listening ＆ Speaking Class. From the students＇ report, teacher＇s log and classroom observation, it is concluded that the three models meet the needs of different students. The key to a successful Viewing, Listening＆ Speaking Class is to set reasonable goals and analyze students＇ needs.展开更多

This paper presents a research in which the interactive web-based college English teaching model intends to reshape the teacher＇s and learner＇s roles in the classroom. Based on the research, an exploration is made --- within the framework of the interactive web-based model --- on the design of ＂teaching model＂ and ＂learning model＂, its application and related potential problems.展开更多

It is a key for popularizing this technology on a large scale to design and make an impactor with excellent performance. This paper presents a suit of method to design the percussive parameters for the oil or gas field by introducing the working principle of back-pressurod impactor, dividing the working periods of impaetor into three phases and establishing the computer emuiational model of percussive parameters. It draws a comparison between the results of model calenlation and experiment on the basis of analyzing the experiment results of impactor. The conclude provides credible foundation for designing and further ameliorating the impactor.展开更多

Making good use of initiative of self- learning is the core element to help students in subjects learning, we constantly improve and perfect teaching concepts and classroom teaching mode to create the space for students to learn and explore actively, make personalized study according to their own characteristics, we make students experience the interest of freedom, autonomy, inquiry learning, enjoy the delight of appearance of personality and vitality of the burst of life vigor. Combining personal teaching experience, we should explore the way to led art students to learn with initiative in principle theoretical classes of their major.展开更多
