We present the analysis of the planetarium usage survey (PLUS), a two-part, mixed-methods initial study investigating planetarium use in the U.S. by undergraduate learners. Seventy-seven planetariums situated on college or university campuses within the U.S. completed an online survey during the fall of 2018 with 11 of those participating in online or phone interviews during the summer of 2019. Planetarium representatives described how their facilities were being used, types of subject materials that were being taught, what content styles are used, and how often learners are attending lessons in the planetarium. Results suggest that undergraduate learners in a planetarium environment are primarily novice, non-STEM (science, technology, engineering, and mathematics) majoring students, learning principally astronomy content, receiving instruction from a live presenter approximately once per month within a given course, for the purpose of receiving visualization-based scaffolding. Audience response systems like iClickers do not appear to be in widespread use in collegiate planetariums, and presented subject matter shows greater variety in planetariums with digital projector capacity as opposed to those with only analog projectors. Refinements to PLUS and future research plans are described.

天文馆在大学教育中的学术用途调查

我们介绍了天文馆使用情况调查（PLUS）的分析，这是一个由两部分组成的混合方法初步研究，旨在调查本科生在美国的天文馆使用情况。美国大学或大学校园内的77个天文馆在2018年秋季完成了一项在线调查，其中11人在2019年夏季参加了在线或电话采访。天文馆代表介绍了他们的设施如何使用，正在教授的主题材料，使用的内容风格以及学习者在天文馆上课的频率。结果表明，在天文馆环境中的本科生主要是新手，非STEM（科学，技术，工程和数学）专业的学生，​​主要学习天文学的内容，在给定的课程中，大约每月一次从实时演示者那里接收指令，以接收基于可视化的脚手架。像iClicker这样的听众响应系统似乎并未在大学天文馆中得到广泛使用，并且呈现的主题显示，具有数字投影仪容量的天文馆与仅具有模拟投影仪的天文馆相比，种类更多。描述了对PLUS的改进和未来的研究计划。所展示的主题显示，具有数字投影仪容量的天文馆与仅具有模拟投影仪的天文馆相比，种类更多。描述了对PLUS的改进和未来的研究计划。所展示的主题显示，具有数字投影仪容量的天文馆与仅具有模拟投影仪的天文馆相比，种类更多。描述了对PLUS的改进和未来的研究计划。
