Digital video fulldome has long been heralded as a revolutionary educational technology; yet the discipline-based astronomy education research literature showing planetarium effectiveness has been sparse. In order to help understand to what extent immersion impacts learning and the effect of the "narrative journey" model of presentation,…

A common challenge among university professors is how to best design undergraduate courses to successfully enhance students' attitudes. To compare which curriculum was more efficient at fostering a positive attitude towards science in general, I studied the impact of two different general education science courses on the attitudes of college…

As discipline-based astronomy education researchers become more interested in experimentally testing innovative teaching strategies to enhance learning in undergraduate introductory astronomy survey courses ("ASTRO 101"), scholars are placing increased attention toward better understanding factors impacting student gain scores on the…

When considering the variety of questions that can be used to measure students' learning, instructors may choose to use multiple-choice questions, which are easier to score than responses to open-ended questions. However, by design, analyses of multiple-choice responses cannot describe all of students' understanding. One method that can…

We compare student learning and perception data from astronomy, physics, and geology courses taught in a traditional classroom with individual desks to the same classes taught in a large auditorium. In a large student sample (1,593 students), there is no clear difference between rooms in measures of failure rates or average final grades. However,…

A mixed-method quasi-experimental study was designed to determine how 130 undergraduates in an introductory astronomy survey course laboratory changed their understanding of scientific inquiry working as individuals in relative isolation compared to working in small, collaborative learning groups when using specially designed astronomy curricula…

Although traditional lectures are still the dominant form of undergraduate instruction, there have been relatively few studies comparing various learner-centered and active learning teaching strategies to one another in order to guide professors in making informed instructional decisions. To study the impact of different active learning…

Neurological research has demonstrated that pre-test verbal preparation improves performance. The well-tested Tower of London puzzle can assess cognitive skills of a wide age range of participants. Preschoolers who talked to themselves about future puzzle moves had greatly improved Tower of London performance over those without such preparation.…

A comparison study between two different methods of conducting online discussions in an introductory astronomy course was performed to determine if the use of Facebook as an online discussion tool has an impact on student participation as well as student response time. This study shows that students using Facebook for their online discussions…

The online writing software Calibrated Peer Review (CPR) is a useful tool for assigning writing assignments in large college classes. In this system, students submit essays online and are guided in how to rate essays using criteria written by the instructor. The instructor does not have to grade the essays, and CPR has educational benefits that…

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…

The topic of Newtonian gravity offers a unique vantage point from which to investigate and encourage conceptual change because it is something with which everyone has daily experience, and because it is taught in two courses that reach a wide variety of students--introductory-level college astronomy ("Astro 101") and physics ("Phys…

This is the final paper in a five-paper series describing our national study of the teaching and learning of cosmology in general education astronomy college-level courses. A significant portion of this work was dedicated to the development of five new "Lecture-Tutorials" that focus on addressing the conceptual and reasoning difficulties that our…

We present results of a two-semester study to determine whether the inclusion of basic animation techniques in PowerPoint presentations provides an additional learning aid, inhibits learning, or has no effect on student learning for students in an introductory astronomy course. We found that (1) students perceive that animated slides are…

In this paper a simplified two-parameter model of the greenhouse effect on the Earth is developed, starting from the well known two-layer model. It allows both the analysis of the temperatures of the inner planets, by focusing on the role of the greenhouse effect, and a comparison between the temperatures the planets should have in the absence of…
