Triadic interaction in clinical task-based interviews with mathematics teachers

A clinical task-based interview can be seen as a situation where the interviewer–interviewee interaction on a task is regulated by a system of explicit and implicit norms, values, and rules. This paper describes how documenting and mapping triadic interaction among the interviewer, the interviewee, and the knowledge negotiated can be used to increase procedural replicability of the interview and accuracy of drawn conclusions about the interviewee’s thinking process. Excerpts from interviews with 25 inservice mathematics teachers working on a task to make up a problem whose solution requires division of two fractions are discussed. The excerpts illustrate the relationship between methodological decisions taken by the interviewer during the interview and the applicability of the interview output to the research questions. A divergent analysis of the interviews with these teachers, which spanned over two years and were conducted by four interviewers, is used to offer a framework for analyzing data collected in clinical task-based interviews.

教师知识分享意愿低落的成因与应对

目前,中小学教师之间互相封闭,缺乏知识分享的情形比较普遍,阻碍了教师的专业发展。本文运用多学科的观点,从不同角度对教师知识分享意愿低落的原因进行分析,并在此基础上提出促进教师知识分享的建议。“毕业一年多,感受最深的就是大学里学的那些教育理论不是很管用……如果老教师能给些指点,或许可以少走些弯路,不过这只是一厢情愿,有时候我甚至觉得他们就在等着我犯错误,他们好看热闹。”我为什么要把这些资料给她们?她们不下功夫,还想白用别人的,哪有这样便宜的事儿?……大家都希望自己教的班级的成绩比别人好,所以互相竞争,彼此提防,哪…
