任务类型对意义协商质量影响的实证研究

通过实验探讨了四种任务类型对非英语专业学生意义协商质量的影响。实验结果表明，任务类型对意义协商的准确度、复杂度和流利度有着显著的影响。研究发现，认知难度低的任务，意义协商的准确度和流利度较高；而认知难度高的任务，则降低了意义协商的流利度和准确度，获得了较高的复杂度。最后，文章提出了在任务教学中提高意义协商质量的建议。

The Effects of Task Types on the Quality and Quantity of Meaning Negotiation

This paper examines how task types give effects on meaning negotiation. Results show that task types have significant influence on accuracy, complexity and fluency of meaning negotiation. Low cognitive demands achieve higher accuracy and fluency, while high cognitive demands receive higher complexity at cost of accuracy and fluency. Finally, some tips are put forward for the task-based language teaching.
