College students associated with the American Chemical Society and Alpha Chi Sigma student/collegiate chapters reach almost 1 million people every year through their informal chemistry education events (chemistry outreach). Previous work has characterized their goals for chemistry outreach, with the most prevalent goal being audience learning. With such large audiences being impacted every year and the goal of audience learning, investigating how these college students approach teaching in informal environments is needed to further understand chemistry outreach practices. This paper presents the results of inductive coding focused on teaching beliefs expressed by these college students as they discussed elephant toothpaste and making liquid nitrogen ice cream for second graders, eighth graders, and general chemistry students. Results indicate three broad categories of beliefs: (1) beliefs about the audience, (2) beliefs about the teaching process/pedagogy, and (3) beliefs about the scope and sequence of the content. While some beliefs are supported by literature on teaching and learning, some of the expressed beliefs are contrary to learning theories and these outreach practitioners’ goal of audience learning. Implications for outreach education are presented in light of these findings as well as potential future investigations of the teaching and learning in chemistry outreach.

“您精打细算会失去一些准确性”：通过外展活动教授化学的大学生的教与学构想

与美国化学会和Alpha Chi Sigma学生/学院分会相关的大学生，每年通过非正式的化学教育活动（化学推广）将近100万人。先前的工作已经确定了他们在化学方面的目标，最普遍的目标是听众学习。每年都会受到如此众多的受众的影响以及受众学习的目标，因此有必要调查这些大学生如何在非正式环境中进行教学，以进一步了解化学推广实践。本文介绍归纳编码的结果，这些归纳代码的重点是这些大学生在讨论象牙膏并为二年级，八年级和普通化学学生制作液氮冰淇淋时表达的教学信念。结果表明，信仰分为三大类：（1）关于听众的信仰，（2）关于教学过程/教学法的信仰，以及（3）关于内容范围和顺序的信仰。尽管一些信仰得到了有关教与学的文献的支持，但某些表达的信仰却与学习理论背道而驰，这些外展从业者的受众学习目标也与之相反。鉴于这些发现以及未来对化学外展教学的研究，提出了外展教育的含义。其中一些表达的信念与学习理论背道而驰，而这些宣传工作者的目标是受众学习。根据这些发现以及对化学外展教学的潜在未来研究，对外展教育的意义进行了介绍。其中一些表达的信念与学习理论背道而驰，而这些宣传工作者的目标是受众学习。根据这些发现以及对化学外展教学的潜在未来研究，对外展教育的意义进行了介绍。
