任务构思条件对汉语二语口语产出中词汇丰富性的影响

The Effects of Task Planning on the Lexical Richness of Foreign Students’Chinese Oral Production

本文以任务构思条件为变量,探索在任务前构思(有准备时间)和在线构思(无准备时间)两种情况下,汉语二语口语产出中词汇丰富性的具体表现和历时三个月的发展变化。研究结果显示,任务构思条件对汉语二语口语词汇丰富性各项测量指标产生的影响不均衡、差异较大,最显著的影响表现在词汇变化度方面,同时对口语表达质量也有比较明显的影响;从纵向发展来看,经过一学期的学习,两种任务构思条件下学习者的口语产出长度、词汇准确性和口语表达质量均有显著提高。
