本研究以质性研究探讨化学系学生如何利用黏土模型来表现甲醛分子的亚微观概念。共有56名学生参加了一个开放式的，长达一小时的定性访谈。志愿者从第一学期的普通化学，有机化学，无机化学和物理化学课程。结果表明，当学生被允许建立自己的模型，而不受传统的模型套件的限制，学生建立创造性和非传统的模型。结果表明，学生的亚微观表征是抗拒改变，尽管采取更多的化学课。
A qualitative investigation of how undergraduate chemistry students used modeling clay to represent their submicroscopic conceptions of a formaldehyde molecule was undertaken. A total of 56 students participated in an open-ended, hour-long qualitative interview. Volunteers from the study were solicited from first-semester general chemistry, organic chemistry, inorganic chemistry, and physical chemistry courses. Results indicated that when students were allowed to build their own models without the restrictions imposed by conventional model kits, students built creative and unconventional models. The results indicated that students' submicroscopic representations are resistant to change, despite taking more chemistry classes.
