15 washback hypothesis raised by Alderson and Wall have been used as the theoretical basis,and the students taking part in the exams in 2005,2006,2007 and 2008 respectively were selected as the subjects.
为了解人文测试这项改革对学生的影响,笔者以Alderson and Wall提出的15条后效假设为理论基础,对2005、2006、2007及2008年参加改革后专八部分考生做了定量定性相结合的调查分析,研究发现:人文测试的增加总体上对学生学习存在着很强的后效作用,但后效作用在学生学习时间和重视度上却在逐年减弱;人文测试的新增对学生产生的后效作用有差异,学生知识面越广此改革后效作用反而越小;此外,笔者还发现人文测试的题型——多项选择,是制约该测试积极后效作用发挥的一个重要因素,由此笔者对人文测试进一步改革提出了建议。
