ABSTRACT
As an obligatory course, English is of great importance to individual
development in China. In reality, however, many learners of English have poor
language abilities due to lack of study strategies. How to help students become
independent and efficient learners and how to train them to use learning strategies
have been a research project for years. In English learning process, vocabulary
learning bears great importance. Inadequate vocabulary not only causes
communication failure, but also limits one’s thinking power. This dissertation probes
into the background, definition and classification of language learning strategies as
well as efficacy of learning strategies by using such instruments as a questionnaire
and a vocabulary test.
Due to the disagreement on the classification and definition of language learning
strategies, this dissertation only introduces some typical and widely accepted
classifications and definitions. 50 vocabulary learning strategies are selected based on
O’Malley and Chamot’s viewpoints and are used to design survey questions for the
questionnaire.
This dissertation tries to investigate the differences of English vocabulary
learning strategies employed by successful and unsuccessful high school students. It
hypothesizes that there is a positive correlation between the strategies the students
employ and their vocabulary learning achievements. If it is proved true, what coping
strategies should the teachers possibly take to help the students to enrich their strategy
repertoire?
The subjects of this study are 100 high school students of Grade Three in
Suzhou No. 1 Middle School, 96 of whose questionnaires and test papers are valid. In
order to estimate the test validity, a questionnaire was handed out to the students and
their teachers to get their opinions to the test paper and their responses show that the
test paper can reflect their vocabulary power. The distributions of vocabulary scores
and strategy scores are also conducted with the help of SPSS. The result shows that
the two sets of scores are in normal distribution.
The students are divided into three groups based on the ranking of the vocabulary
test scores: the top 32 students are represented by G1, the bottom 32 students are
represented by G3, and the middle 32 students are represented by G2. For
