We tested the educational effectiveness of an inquiry-guided approach (Lee et al., 2004; Prince & Felder in "Journal of Engineering Education, 95," 123-138, 2006) to teaching a possible outcome of statistical hypothesis testing known as type 1 error. The approach consisted of showing participants an animated space exploration video.…

Hurricane and galaxy tidal effect are routine teaching topics in community college first year science courses, but there is a knowledge gap without a quantitative discussion of the physics of non-inertia frame. A survey of YouTube videos posted by Education Centers and professors showed that the hand-waving conceptual explanation is the most…

The evolving landscape of higher education demands integrating advanced technologies to foster engaging and inclusive learning environments. This paper examines the practical integration of Stellarium, a virtual planetarium software, and ChatGPT, an AI conversational agent, in an asynchronous online undergraduate astronomy course. Stellarium…

Due to the COVID-19 pandemic and adapting the classes urgently to distance learning, directing students' interest in the course content became challenging. The solution to this challenge emerges through creative pedagogies that integrate the instructional methods with new technologies like augmented reality (AR). Although the use of AR in science…

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…

Most students have interacted with scientific representations that are used as teaching resources in schools. Often these external representations present challenges for understanding. By utilizing a framework based on an inferential, epistemic approach to scientific representations, we have analyzed students' representational constructions of the…

Investigating stars can be difficult. The five-day unit presented in this article is designed for fifth graders to work toward Next Generation Science Standard (NGSS) performance expectation 5-ESS1-1, with each lesson lasting about 30 minutes. Students investigate the relationship between the brightness of light and distance, apply their…

Background: In learning astronomy, students need to shift between 3D and 2D representations involving complex interactions between the body and material environment. Little attention has been paid to the iconic nature of this astronomical diagramming. Purpose: This research explored the value for students of diagramming to reveal the structural…

This dissertation is composed of three studies linking general education astronomy to student performance, course-taking, graduation, and identity. The first study examined demographic and academic predictors of astronomy performance among a cohort of N=1,909 community college students enrolled in astronomy courses in a large suburban community…

The theory of the Big Bang is accepted nearly universally among the scientific community. However, there is a small cadre of individuals who dispute this consensus and they point to a handful of datums that don't fit into the picture. One such datum is the existence of a star with an age reported to be older than the cosmos itself. This star is…

At a conference on educational physics, someone described a series of multiple-choice problems to test students' ideas about various mechanical phenomena. One of the problems questioned students' conceptions about the shape of the Earth's orbit in the solar system. The question was as follows: "Which of the following schematic illustrations…

The Sun is a central feature to the human experience. It is found in many familiar idioms like "nothing new under the Sun." It defines our days, makes our planet habitable, and is the ultimate origin of your last meal. Yet how do we understand how it works?

Stellar aberration is the phenomenon whereby the observed angular position of a star depends on the relative motion between the star and Earth. Specifically, a telescope must be tilted slightly into the direction of motion of Earth relative to the star. There are in fact three different angular positions of interest: the observed position of the…

Using Indigenous Astronomy and the arts, I respond to Wayfinding with a conceptual image that represents my cultural understanding of the idea of navigation.

Massive open online courses (MOOCs) experienced a resurgence in popularity due to the COVID-19 pandemic. In this work, we studied participants in an astrobiology MOOC offered on Coursera since April 2019. Using a modified version of the Science Motivation Questionnaire II, we examined the primary motivational factors of the participants, how those…
