这项研究的目的是调查问题的性质，这些问题会以微粒的形式引起回答。海达尔和亚伯拉罕在他们的物理变化概念测试(PCCT)中使用的日常问题和科学问题之间的科学内容分级，开发了另外四个问题。测试的概念是溶解、不溶、饱和、扩散、物质状态和渗出。大约1066名大一化学学生每人通过互联网接受了一份测试表，测试表从日常内容发展到科学内容，随机涵盖了所有六个概念。学生的逻辑推理能力与他们使用的微粒术语之间没有很强的相关性。这项研究中没有一个概念显示出使用微粒理论的完全正确回答的比例很高。然而，这项研究确实发现，无论是在日常生活中还是在科学术语中，学生们都会立即被问题中的词语所暗示。这一发现表明……
The goal of this study was to investigate the nature of questions that elicit responses in particulate terms. Four additional questions were developed with a gradation of scientific content between the everyday and scientific questions used by Haidar and Abraham in their Physical Changes Concepts Test (PCCT). The concepts tested were dissolution, insolubility, saturation, diffusion, states of matter, and effusion. Each of the approximately 1066 freshman chemistry students was administered a test form via the Internet, which progressed from everyday to scientific content and randomly covered all six concepts. No strong correlations were found between the students' logical reasoning ability and their use of particulate terminology. None of the concepts in this study showed a high percentage of completely correct responses using the particulate theory. However, the study did find that students are immediately cued by the words in the questions, whether in everyday or scientific terms. The findings indicate t...
