This qualitative study examined how different aged Chinese and Czech students constitute the meaning of teacher by the phenomenological approach MCA which is invented by R.Sages. Particular attention was paid to the findings which was iterated on the virtue forming rather than the knowledge apprehension. However, bad impression of teachers was constantly emerged during the whole process of meaning constitution, both in China and Czech. While they all held the beliefs of positivewill in future. The analysis implied that students were fuzzy with the relationship within the context of teaching and learning,while for teachers, there existed the discrepancy in aligning beliefs with practice. 展开更多

The task-based approach has been gaining more and more popularity in recent years. Unlike the traditional language teaching approach, which puts much emphasis on the teaching and learning of language forms and skills, it regards the language process as one of learning through doing, emphasizes the central role of meaning in language use and insists that students should learn more effectively if they are fully engaged in a language task. However, due to the lack of an appropriate language environment and limited time for English study, Chinese students may not make as much progress as expected in the unconscious internalization of authentic language by focusing primarily on meaning. In fact the meaning of a language can not be separated from its form. The accurate expression of meaning depends on the proper use of language form. Therefore, in the application of the taskbased approach, we should not neglect the study of language form. This paper analyses the causes for Chinese students' low spoken English proficiency, describes the theoretical foundation and actual practice of the task-based approach, discusses its implications for teaching oral English and makes some proposals for its appropriate application. 展开更多

Cognitive models must be able to adapt the students learning behaviors dynamically.In our point of view,the processes of learning and understanding are,in nature,the procedure that gains the meaning of the object to be learned.So,ICAI cognitive models should reflect the meaning structure of the domain knowledge in students mind.According to this view,we developed the meaning theory of Ludwig Wittgenstein,and proposed the concept of meaning conjoinism.On the basis of the meaning conjoinism we proposed a meaning oriented ICAI cognitive model and its corresponding teaching tactics.Furthermore,we developed an ICAI system named Thinking and the efficiency of our proposal has been demonstrated. 展开更多

This study proposes a teaching system environment for the training of English guides of stone inscription relics based on analysis and describes the roles played by each element in this system environment. The elements listed in the system environment can contribute themselves only under the support of the whole system environment.
