The Effect of Cooperative Learning on the Word-building Task Abstract Recently, cooperative learning has been the hot spot of people’s attention。 As one of the mainstreams of today’s learning theories, more and more social psychologists and educationalists advocate cooperation in students’ learning。 The purpose of this study is to investigate the effect of cooperative learning on the word-building task in EFL classes。 One hundred and fifty students, pided into experimental group and control group, participated in this study。 In the experiment, the participants in the experimental group completed the word-building tasks of different degrees in pairs, whereas the participants in the control group accomplish the same tasks by inpidual。 Before this experiment, students in experimental group did similar tasks inpidually。 Then they did the tasks for four weeks and three times a week as how they did in the former experiment。 After four weeks, the students in experimental group did the similar tasks by inpidual again。 The results showed that participants in the experimental group achieved significantly higher scores than the participants in the control group。 And compared the tasks of low level and high level, the participants in the experimental group had more obvious superiority on tasks at medium level。 These reveals that cooperative learning helps EFL learners achieve better in co-construction of morphological knowledge。 And the effect of cooperative learning do varies with the difficulty of tasks。  73641

探究合作学习对构词任务的影响

摘要近来，合作学习已经成为人们关注的热点。作为当今国内呼声最高的学习理论之一，越来越多的教育学家和社会心理学家提倡学生在学习过程中进行合作。本文所要研究的目的是为了探究在非母语英语课堂中，合作学习对重构形态学知识的影响。共有150个学生参与了此次研究，分别被分到实验组和对照组。实验一中实验组的同学两人一组合作完成由不同难度题目构成的任务，而相同的任务，对照组的同学则需要单独完成。此外，在实验一前实验组的同学先进行一次独立完成任务的实验，然后每周进行和实验一相同的实验三次，共四周。四周结束后，实验组的同学再进行一次独立完成任务的实验。实验结果表明实验组的同学的得分比对照组的同学更高。中等难度的任务在短期合作学习中比低难度和高难度的任务更能体现优越性。而在长期的合作学习中，低难度和中等难度的任务都能体现优越性，而合作学习对高难度的任务似乎不起作用。
