Abstract

The viscous behavior of fluids can be observed in numerous everyday situations. Therefore, it is reasonable to assume that people, since they are usually not specialists in fluids’ flow behavior, possess naïve conceptions about the viscous behavior of fluids. These conceptions more or less deviate from corresponding scientific explanations. Qualitative studies with preschool children and secondary school students from Germany have already identified various naïve conceptions about the viscous behavior of fluids (e.g. that the density or stickiness of a substance explains its viscous behavior). Within the present study, we explore the question of whether similar naïve conceptions can also be found among adults around the globe. To this end, based on previous research, an online questionnaire was developed to survey adults worldwide regarding their naïve conceptions about the viscous behavior of fluids. The survey was conducted anonymously, online, and voluntarily in spring 2023; participants were recruited via SurveySwap. A total of 406 adults from all regions of the world (primarily Europe and North America) participated in the survey. In this paper, we report and discuss the main findings of this online survey.

成人眼中液体的粘性行为：全球调查

流体的粘性行为在日常生活中随处可见。因此，我们有理由认为，由于人们通常不是流体流动行为方面的专家，他们对流体的粘性行为有着天真的概念。这些概念或多或少地偏离了相应的科学解释。对德国学龄前儿童和中学生进行的定性研究已经发现了关于流体粘性行为的各种幼稚观念（例如，物质的密度或粘性可以解释其粘性行为）。在本研究中，我们将探讨全球成年人中是否也存在类似的幼稚观念。为此，我们在以往研究的基础上，编制了一份在线问卷，调查全球成年人对流体粘性行为的幼稚观念。调查于 2023 年春季以匿名、在线和自愿的方式进行，参与者通过 SurveySwap 征集。共有来自世界各地（主要是欧洲和北美）的 406 名成年人参与了调查。在本文中，我们将报告并讨论此次在线调查的主要结果。
