基于Rasch模型的生物学科职前教师错误分析能力研究

Study on the Error Analysis Ability of Pre-service Teachers in Biology Based on Rasch Model

为了调查生物学科职前教师对学生错误进行合理分析处理的能力,本研究基于Rasch模型,构建了职前教师错误分析能力发展模型.通过对99名中学生和125名职前教师进行问卷测试,展开对生物学科职前教师错误分析能力的研究.研究显示70.00%受试者对学生错误分析的能力仅处于初阶水平,表明本研究中生物学科职前教师对学生的错误分析能力亟需提高.

In order to investigate the ability of pre-service biology teachers to analyze students′errors reasonably,this study uses Rasch model to construct the developing progression of this important ability.By carrying out a paper-and-pen test on 99 middle school students and 125 pre-service teachers,the research on the error analysis ability of pre-service biology teachers was conducted.Results have shown that 70.00%respondents ability to analyze students′errors are only at an early level.Their ability to analyze students′errors need to be improved.
