The General Education Astronomy Source (GEAS) project is an astronomy education program based at New Mexico State University (NMSU). We have developed a set of resources for traditional and distance-learning undergraduate introductory astronomy courses. These materials aim to increase success for underrepresented students in New Mexico and throughout the nation by addressing two key needs. They provide a mechanism for students to review basic math and science and explore current astronomy topics at an adjustable pace, and they allow students whose work and family commitments complicate in-class, on-campus attendance to successfully pursue an accredited laboratory-based science course, mandatory in statewide graduation requirements.
The demand for higher education distance learning laboratory science courses is high in New Mexico, but offerings are limited. There is a strong unmet need, as a substantial fraction of students find it challenging to migrate to university campuses rather than remaining in the surrounding areas, and another fraction have work and family responsibilities which make it difficult for them to attend afternoon and evening class sessions. Astronomy laboratory sections fill to only 40% when held in the late afternoon or evening at NMSU, while the demand for sections which meet earlier in the day overwhelms the supply. Due to the limited availability of laboratory-appropriate space on campus, we are already at capacity during early time slots, and thus students who need these courses to graduate are turned away every semester.
By increasing access to laboratory science courses through distance learning, we can remove a significant barrier to completion of the bachelor's degree in New Mexico. Our program aids in integrating promising New Mexico students with an incipient interest in STEM fields into the college environment, a particularly crucial aid for the large fraction who form the first generation of high school graduates within their families. It can improve retention rates for at-risk students with limited math and science backgrounds, while stimulating interest in the pursuit of Science, Technology, Engineering, and Mathematics (STEM) careers for STEM-field majors. Our materials can also deepen the scientific training for pre-service teachers and thus improve the K-12 educational experience locally.
Our program comprises four primary components, based on 26 lecture modules starting with exploration of the solar system and ending with the cosmology of the early universe.
An extensive, interactive self-review library covering all 26 lecture modules provides students with instruction tailored to their rate of learning and mathematical abilities, with personal feedback, as they integrate new knowledge into their existing view of the universe. Students each complete roughly 1,600 problems over a semester, drawing from an archive of over 12,000 questions presenting both conceptual and mathematically-focused challenges.
An instructor analysis tool for reviewing student work archives copies of each exercise completed by every student, including the details of incorrect answers, and reveals trends with topic and time for individuals and groups. Instructors are able to monitor individual and group progress, tracking every facet of student action and the global response to individual topics of study.
A set of laboratory exercises suitable for in-class or distance learning introduces the scientific method of experimentation and presents key experiments in observational astronomy tied to the lecture topics. Students perform experiments, analyze data, and write laboratory reports using an interactive system which provides continuous feedback from instructors and peers through online document-sharing.
Experiments are divided between hands-on projects that allow students to plan and execute their own experiments and exploration of modern astronomical data based on images and spectra of planets, stars, and galaxies.
Audio recordings for each lecture module are synced to lecture slides, allowing students to interweave written and audio materials and to listen to (and review) podcasts of lectures while exercising or traveling.
A series of short films highlights diverse members of underrepresented groups with careers in astronomy-related STEM fields, reinforcing a message of inclusion for underrepresented students in the future STEM generation. Our stars are astronomers, engineers, librarians, and even museum directors, all of whom have productive careers in astronomy-related areas.
Our staff invites you to learn more about our astronomy education program. We are interested in collaborating with science instructors at four-year institutions and community colleges and in dual-credit high school programs, to extend the reach of astronomy education in the Southwest Border Region and beyond. If you think that you would benefit from using our resources in an educational or outreach setting, or would like to learn more about our program, please contact us.
