'The Necessity of the Cultural Education in a Second Language Class' was written to prove the necessity and importance of introducing culture in a second language class. Why a second language? And why a cultural education in a second language class? The answers to these questions are, I believe, that the main goal of teaching a second language is to help each student (1)to have the clear recognition of the difference between his or her own culture and other cultures (2)to create a new value judgement by having that recognition (3)to love and respect other cultures as well as his or her own culture. Since we are very familiar with the language of English, I chose English as my target language for this paper. There are 6 chapters besides Introduction and Conclusion in 'The Necessity of the Cultural Education in a Second Language Class' Chap.1: The Propose of English Education Chap.2: The Definition of Culture Chap.3: The Meaning of Teaching Culture in a Second Language Class Chap.4: The Analysis of TOTAL Chap.5: The Necessity of Cooperation with Other Subjects Chap.6: The 8 Main Methods of Teaching English as a Second Language I will be very happy if this paper can be a help for the second language learners as well as the second language teachers.
