本文报告了一项关于十年级学生在正式教学之前对三个矢量概念：位置、位移和速度的理解的研究。本文对研究的三个方面进行了讨论和报道。第一个方面是对主题的概念分析，用来设计合适的采访问题；第二方面是对访谈数据进行压缩时使用的规则评估方法，第三方面是对参与访谈的学生所获得的实质性结果。概念分析产生了十个“隐式向量特征”，访谈围绕这些特征构建。从这些访谈中，使用类似于siegler报告的技术开发了许多推断规则。1如此导出的规则表明，虽然大多数受访者似乎在使用与物理学家模型相似的规则来处理一些矢量特征，但对于大多数特征，他们使用的规则只是从物理学家的角度对现象的部分描述。但这些规则只是对学生框架的初步描述，需要在随后的研究中进行测试，以检验它们在涉及这些向量概念的其他上下文中的有效性和普遍性。
This article reports on a study of grade ten students' understanding, prior to formal instruction, of three vector concepts: position, displacement, and velocity. Three aspects of the study are discussed and reported. The first aspect is the conceptual analysis of the subject matter which was used to devise appropriate interview questions; the second aspect is the rule assessment methodology which was used in the compression of the interview data, and the third aspect is the substantive results obtained from interviews with the participating students. The conceptual analysis yielded ten “implicit vector characteristics” around which interviews were constructed. From these interviews a number of inferred rules were developed using a technique similar to that reported by Siegler.1 The rules so derived suggest that while a majority of respondents appeared to be using rules similar to the physicists' model for a few vector characteristics, for most characteristics they used rules which are only a partial description of the phenomena from a physicist's point of view. But these rules are only tentative descriptions of students' frameworks and need to be tested in subsequent studies to examine both their validity and generality in other contexts involving these vector concepts.
