| Vocabulary is one of the three major elements of language.Learning a kind of foreign language must have a good foundation of vacabulary.The memory of English vocabulary plays an important role in learning English,especially in the middle school stage.The English vocabulary teaching in China is mainly faced with the problems of "de-contextualization","ignoring the connection and use of vocabulary" and "ignoring the student’s principal parts in learning".Elaboration is a process in which people consciously link the target information with the memorized information.The special clue information generated by elaboration can help to enhance memory.The elaboration of vocabulary can improve the vocabulary memory effect,and the vocabulary teaching method that elaborates words into context has been advocated.Multimedia teaching is an inevitable trend of the development of the times.Through multimedia,vocabulary context can be displayed more intuitively,and different multimedia teaching materials can have an effect on the effect of elaboration.Based on elaboration theory,this paper proposes two different vocabulary elaboration methods which are"student elaborating context by themselves" and "teacher guiding students to elaborate context" and two different level of elaboration which are "elaboration of sentence context " and "elaboration of short text context" in the view of current situation of English vacabulary teaching.This paper will apply the four teaching methods into practice teaching and compare the memory effect pruduced by them through two experiments using forward-backward mutimedia teaching materials.The experiment 1 data shows that the effect of "teacher guiding students to elaborate context" is better than that of "student elaborating context by themselves",and forward design is better than reverse design.In addition,in the case of “student elaborating” context by themselves,forward design has a relative advantage over backward design;and under the conditon of backward design,"teacher guiding the effect of "elaboration of short text context" is better than "elaboration of sentence context " and forward design is better than backward design.In addition,at the two levels of elaborative level,forward design has a relative advantage over backward design;at the two levels of multimedia information design elements,"elaboration of short text context" has a relative advantage over "elaboration of sentence context ".The final conclusion of this study is: the deeper the level of elaboration,the deeper the memory,and establishing a semantic association between vocabulary and vocabulary can enhance the memory effect of the vocabulary.That students passively learn the knowledge of vacabulary is not the only way of vocabulary learning.It should also be advocated that developing the students’ strategies of independent learning of vocabulary which combine the “teaching” and “learning” perfectly.Therefore,teachers should make full use of the advantages of multimedia vocabulary teaching and take students as the principal parts of learning,guiding students to use a variety of learning strategies,improving their activity of vocabulary learning,developing and cultivating the ability of using vocabulary,and finally maximizing the effect of vocabulary memory. |
