A Comprehensive Evaluation on Chinas EFL Learners' Interlanguage Fossilization Based on Fuzzy Sets

The term fossilization first appeared almost 40 years ago. But the previous studies remains to be lack of the overall scientific and systematic evaluation on fossilization. This study intends to construct the evaluation index system and evaluation model on fossilization more completely, systematically, scientifically and practically, based on the theory of fuzzy sets and fossilization theory. Firstly, a seminar is held with Chinas 90 college English teachers to evaluate the importance of each index. Then, the quantified evaluation model based on the fuzzy sets is constructed and developed to test the Chinas EFL Learners Interlanguage Fossilization and the scores of evaluation on fossilization are calculated and the tests of speaking and writing have been administered. In order to test the effectiveness of the evaluation model, the study investigated 370 college students Chinas EFL Learners Interlanguage Fossilization in China. With the test results, the correlation coefficient has been done among them. There is a strong relationship among Chinas EFL Learners Interlanguage Fossilization, their speaking and writing. The findings of the study demonstrate that the evaluation model is highly applicable and valuable.
