中美高校理科教师两种科学认识论内在关系的实证研究

Empirical Research on Relationships between Two Kinds of Scientific Epistemology Held by Chinese and United States Science Teachers in the University

科学认识论是国外科学教育领域的热点问题,其中教师对科学本质和科学探究的认识作为两个核心议题成为研究的主体,对科学课程的理论和实践产生重要的影响。本研究考察和比较中美高校理科教师两种科学认识论之间的关系,利用混合研究并行法,通过科学本质问卷VNOS-D和科学探究问卷VOSI-S以及随后的深度访谈,对中美来自于上海和芝加哥各100位大学理科教师展开调查。研究结果表明,中美高校理科教师两种认识论处于不同的阶段和类型,其因果性不同,类型之间也存在国别内部的相关性,因此我国高校教师教育也有相对应的特征。
