4.1  Results 

The  results of this experiment include two parts. The first part was the results of three vocabulary tests (target word test,  immediate-test, and delayed-test) on the 4th, 8th, and 12th week separately. The scores in the target words test, immediate-test and delayed-test were compared with each other to see if the subjects acquire more words after watching video. Besides, comparisons were made between Group A and Group B about their tests scores with the help of Independent Sample T-test. The second part in is the result of the interview, which was con cluded by asking the subjects some relative questions about this teaching method.    In order to supervise the experim ent process and investigate the research questions. The results of the pre-test we re analyzed by an independent sample t-test. Similarly, the results of the target words test, immediate-test and delayed-test on the 4th, 8th, 12th week and also the result of post-test were listed and analyzed here separately. All the test results are collected and analyzed by SPSS 17.0. Following are the com parisons between those tests.

Besides, most of  the subjects get a progress in vocabul ary  size after a sem ester’s  study,  which illustrates this is an efficient way for learning vocabulary.Second,  tasks with different involvement load have different effects on students’ incidental vocabulary acquisition in audio-visual context. Students with higher task involvement load learn better than student  with lower task involvem ent load, which testified  the Involvem ent  Load hypothesis.  In addition, students with higher tas k involvement load also retain better than lower ones本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
