Ribaudo, Joseph – Physics Teacher, 2016
Without question, one of the most useful tools an astronomer or physicist can employ to study the universe is spectroscopy. However, for students in introductory physics or astronomy classes, spectroscopy is a relatively abstract concept that combines new physics topics such as thermal radiation, atomic physics, and the wave and particle nature of…

Duerden, Amanda; Moon, Nicole; Grubbs, G. S., II – Journal of Chemical Education, 2021
Few laboratory exercises exist that introduce undergraduate students to both the concepts and instrumentation used in rotational spectroscopy. Because of this gap in undergraduate laboratory training, a teaching laboratory for the pure rotational spectroscopy of benzonitrile has been developed and reported. Owing to benzonitrile's recent discovery…

Pfaender, J.; Gratton, L. M.; Rosi, T.; Onorato, P.; Malgieri, M. – Physics Teacher, 2022
In the last decades spectroscopy began to play an essential role in physics education research with the recognition that atomic spectra constitute a good occasion to study the concepts of quantum mechanics. Moreover, activities in which atomic spectra are studied in order to understand star structure and evolution have proved particularly engaging…

Wallace, Colin S.; Chambers, Timothy G.; Prather, Edward E. – Physical Review Physics Education Research, 2018
[This paper is part of the Focused Collection on Astronomy Education Research.] This paper presents the first item response theory (IRT) analysis of the national data set on introductory, general education, college-level astronomy teaching using the Light and Spectroscopy Concept Inventory (LSCI). We used the difference between students' pre- and…

Laci Shea Brock – ProQuest LLC, 2021
Equally as important as growing the body of human knowledge through scientific discoveries and analysis is relaying this information to the general public in a digestible manner to establish a scientifically literate society. This dissertation approaches the multifaceted issue by combining an in-depth study of brown dwarf binary atmospheres with…

Kaltcheva, Nadia; Nenkova, Maia – Physics Education, 2021
Many introductory astronomy courses include concepts related to basic stellar properties. In general, these are concepts that originate from the human perception of starlight. This observational aspect is not easy to incorporate in the classroom. We explore if these concepts could be developed using the built-in data in a planetarium software.…

White, Douglas W. – Physics Teacher, 2022
Laboratory astrophysics and astrochemistry are emerging fields highlighting the importance of laboratory simulations and experiments to benefit remote observations. In particular, ice mixtures found in the outer solar system may offer insight into the early evolution of organic molecules. H[subscript 2]O-ice mixtures containing other species such…

Wallace, Colin S.; Prather, Edward E.; Hornstein, Seth D.; Burns, Jack O.; Schlingman, Wayne M.; Chambers, Timothy G. – Physics Teacher, 2016
Light and spectroscopy are among the most important and frequently taught topics in introductory college-level general education astronomy courses (hereafter Astro 101). This is due to the fact that the vast majority of observational data studied by astronomers arrives at Earth in the form of light. While there are many processes by which matter…

Mowry, Curtis; Milofsky, Rob; Collins, William; Pimentel, Adam S. – Journal of Chemical Education, 2017
This laboratory introduces students to laser-induced breakdown spectroscopy (LIBS) for the analysis of metals in soil and rock samples. LIBS employs a laser-initiated spark to induce electronic excitation of metal atoms. Ensuing atomic emission allows for qualitative and semiquantitative analysis. The students use LIBS to analyze a series of…

Brockington, Guilherme; Testoni, Leonardo André; Pietrocola, Maurício – Physics Education, 2015
The continuing fascination of young people with celestial bodies leads them to pose challenging questions to their science teachers, such as how was the universe born? How were the stars formed? In this paper we present an extremely inexpensive but highly engaging activity to teach the basics of spectroscopy. Guided by the question "how do…

Rudolph, Alexander L. – Astronomy Education Review, 2013
The increasing use of interactive learning [IL] strategies in Astro 101 classrooms has led some instructors to consider the usefulness of a textbook in such classes. These strategies provide students a learning modality very different from the traditional lecture supplemented by reading a textbook and homework and raise the question of whether the…

Bardar, Erin M. – Astronomy Education Review, 2008
This article presents results from a two-semester field test of the Light and Spectroscopy Concept Inventory (LSCI). Statistical analysis indicates that the LSCI has the sensitivity to measure statistically significant changes in students' understanding of light-related topics due to instruction in introductory astronomy courses and to distinguish…

Bardar, Erin M.; Brecher, Kenneth – Astronomy Education Review, 2008
In this article, we present an overview of a suite of light and spectroscopy education materials developed as part of Project LITE (Light Inquiry Through Experiments). We also present an analysis of how introductory college astronomy students using these Project LITE materials performed on the Light and Spectroscopy Concept Inventory (LSCI)…

Rudolph, Alexander L.; Gonzaga, Vicente; Prather, Edward E.; Brissenden, Gina; Consiglio, David – Astronomy Education Review, 2010
This is the second in a series of reports on a national study of the teaching and learning of astronomy in general education, nonscience major, introductory college astronomy courses (hereafter referred to as Astro 101). The analysis reported here was conducted using data from nearly 2000 students enrolled in 69 Astro 101 classes taught across the…
