Abstract:Learning strategy is a series of effective learning rules, approaches, skills and regulative ways. Using learning strategies properly can help learners acquire language effectively. Vocabulary learning is prominent for English learning, because vocabulary constitutes the basic building blocks of English sentences. In the process of vocabulary learning, effective use of vocabulary learning strategies increases not only the vocabulary learning efficiency, but the quality of English leaning. So it is necessary to explore vocabulary learning strategies to help students learn English vocabulary more effectively. This study made a survey on 150 junior middle school students in Mengzi NO.2 middle school, Yunnan province. It aims at finding the students’ attitude towards English vocabulary learning and the present situation of using vocabulary learning strategies. Based on the results, the writer found that there were some problems existing in the process of leaning English vocabulary, for example, the students were not highly motivated in vocabulary learning; they did not use vocabulary learning strategies widely; they learned vocabulary without context; and they did not make use of English learning resources. This study emphasizes that using constructivism to guide English vocabulary learning is necessary. From the perspective of constructivism, the writer put forward three vocabulary learning strategies to promote the development of individualized vocabulary methods and the vocabulary learning ability on the part of students. 

Keywords: English vocabulary learning; constructivism; learning strategies
