The Influence Of Unequivalent Amount Of Listening Input On College Learners' Oral English Performance

The relationship between input and output and their relationship with SLA are among the focuses that applied linguists and foreign language teachers all over the world care about all the time. Different linguists hold different views about these problems, especially about the influence of unequivalent amount of listening input on college learners' oral English performance. In this thesis, the author discusses this problem emphatically through an experiment study from the views of SLA and language teaching. The results in this experiment prove that large amount of comprehensible listening input can improve learner's listening ability significantly, but learners' oral performance hasn't changed significantly.On the relationship of input and output, Stephen Krashen(1983) put forward the Input Hypothesis, which is simply stated: 'human acquire language in only one way-by understanding messages or by receiving comprehensible input'. But Swain(1985) expresses her disapproval of it by putting forward the Comprehensible Output Hypothesis, in which she insists that comprehensible input is important, but it is not the only way to acquire a language, learners also need to produce comprehensible output in order to acquire a language. In this thesis, in order to test whether unequivalent amount of comprehensible listening input has influence on collage learners' oral English performance, an experiment lasting for twelve months is carried out. To obtain the experiment data, both the control and experiment groups all receive pre-and post-tests. All the participants are chosen randomly from students who entered Lanzhou University in the year of 2004 (English and art majors excluded). Those of EG are chosen from students whose English courses have network part, and those of CG are chosen from the other part. Before the post-test, the average input and output time per week of them is investigateded by a questionnaire. The data are processed by SPSS 11.0 software. The result shows that the control and experiment groups differ only in comprehensible listening input amount significantly. The listening input amount of experiment group is more than that of control group. When the participants are doing the assigned oral task, recordings are made at the same time. Through analyzing all the participants' transcriptions, data of complexity,...
