本书研究了二语习得领域,不同的任务设计和执行因素(如任务类型,任务执行标准,和任务类型重复)对中国英语学习者口语产出的影响。参与者的语言产出分别从三个方面进行评估,即多样性,准确性和流利性。结果显示任务类型对语言产出的三个方面都产生了显著影响。任务执行标准总体上对语言产出的短语多样性和流利性均产生了显著的正面影响。此外,重复同一类型的任务会显著提高准确性和修正流利性,但却牺牲了语速和停顿流利性。这一研究有助于理解预设的任务执行标准对二语学习者语言产出质量的潜在影响,同时对语言教学提供了有价值的启示。

One hundred and forty-four Chinese learners of English participated in the study. They were randomly paired and assigned to either a map task or a picture-story task. Two exemplars of each task type were used on separate occasions (one week apart). Each task group was further divided into two experimental groupshigh criterion (HC) and low criterion (LC) and a control group. Both the HC and the LC groups were informed at the outset that they would be asked to perform an additional activity upon completion of the baseline task. The HC speakers undertook a more demanding posttask activity, and the LC group a less demanding one. No extra posttask requirement was imposed on the control group. A wide range of measures were employed to evaluate the participants' language production in terms of complexity, accuracy and fluency.
