二语习得研究是一门新兴学科。学科特性决定了该领域的研究通常都是实证性的。从其中的量化研究采用的数据采集方法看,大致可以分为问卷调查法和语料库研究法两种。后者使用的语料库包括本族语语料库和学习者语料库。这两种方法各有所长,也都有一定局限。合理运用这些方法,实现优势互补,能够使我们更好地考察学习者的语言发展状况,提高研究、教学的效率和效果。
Second language acquisition research is a new discipline. The nature of the subject determines that research in this area is usually empirical. According to the data collection method adopted in quantitative research, there are two kinds of methods: questionnaire survey and corpus research. The latter corpus includes a native language corpus and a learner corpus. These two methods have their own advantages and disadvantages, but also have some limitations. Rational use of these methods to achieve complementary advantages can enable us to better examine the learners’ language development and improve the efficiency and effectiveness of research and teaching.
