摘要:

黑洞事件视界的突破性图像在2019年4月引起了公众的注意和想象力,它是利用干涉测量的力量捕获的:许多独立的望远镜共同努力,以令人难以置信的细节观察宇宙。许多最近的天体物理学发现已经彻底改变了科学界对宇宙的理解,这些发现都是由LIGO,ALMA和事件视界望远镜等干涉仪完成的。天文学101的导师希望他们的学生学习这些发现背后的科学,必须教授干涉测量学。几十年的研究表明,使用主动学习策略可以显着提高学生的学习,并减少不同人口群体之间的成就差距,而不是传统的基于讲座的教学。作为创建干涉测量积极学习材料的努力的一部分,我们开发并测试了一个新的讲座,以帮助天文101学生了解天文干涉仪的关键属性。本文介绍了这一新的讲座,并提出证据,其有效性进行了一项研究,266天文101学生在北卡罗来纳大学教堂山。

英文摘要:

The ground-breaking image of a black hole's event horizon, which captured the public's attention and imagination in April 2019, was captured using the power of interferometry: many separate telescopes working together to observe the cosmos in incredible detail. Many recent astrophysical discoveries that have revolutionized the scientific community's understanding of the cosmos were made by interferometers such as LIGO, ALMA, and the Event Horizon Telescope. Astro 101 instructors who want their students to learn the science behind these discoveries must teach about interferometry. Decades of research show that using active learning strategies can significantly increase students' learning and reduces achievement gaps between different demographic groups over what is achieved from traditional lecture-based instruction. As part of an effort to create active learning materials on interferometry, we developed and tested a new Lecture-Tutorial to help Astro 101 students learn about key properties of astronomical interferometers. This paper describes this new Lecture-Tutorial and presents evidence for its effectiveness from a study conducted with 266 Astro 101 students at the University of North Carolina at Chapel Hill.
