An Online Tutor for Astronomy: The GEAS Self-Review Library
We introduce an interactive online resource for use by students and college
instructors in introductory astronomy courses. The General Education Astronomy
Source (GEAS) online tutor guides students developing mastery of core
astronomical concepts and mathematical applications of general astronomy
material. It contains over 12,000 questions, with linked hints and solutions.
Students who master the material quickly can advance through the topics, while
under-prepared or hesitant students can focus on questions on a certain topic
for as long as needed, with minimal repetition. Students receive individual
accounts for study and course instructors are provided with overview tracking
information, by time and by topic, for entire cohorts of students. Diagnostic
tools support self-evaluation and close collaboration between instructor and
student, even for distance learners. An initial usage study shows clear trends
in performance which increase with study time, and indicates that distance
learners using these materials perform as well as or better than a comparison
cohort of on-campus astronomy students. We are actively seeking new
collaborators to use this resource in astronomy courses and other educational
venues.Comment: 15 pages, 9 figures; Vogt, N. P., and A. S. Muise. 2015. An online

Online social networking and psychological experiences:the perceptions of young people with mental health difficulties
Objectives This study explores the interaction between online social networking experiences and wellbeing in 12 young people accessing mental health services. Methods Data from semi-structured interviews was analysed using Grounded Theory methodology. Results “Threats and judgement” and “connection and support” were experienced by adolescents, facilitated by having continuous access to a vast social network. These experiences influenced adolescents' psychological wellbeing, mediated by their responses to threat and judgement and maintaining “safe sharing” with their network. Social network use was conceived as a gamble of balancing its potentially positive and negative impact in a culture in which social network use appears to be unavoidable. Conclusions The findings indicate the importance of routine assessment and formulation of social networking use in understanding adolescents' psychological distress. Furthermore, a range of opportunities exist for clinicians to utilise the anonymity and peer support that social networks offer to broaden the range of mental health services offered to young people
The General Education Astronomy Source (GEAS) Project: Extending the Reach of Astronomy Education
We present a set of NASA and NSF sponsored resources to aid in teaching astronomy remotely and in the classroom at the college level, with usage results for pilot groups of students. Our goal is to increase the accessibility of general education science coursework to underserved populations nationwide. Our materials are available for use without charge, and we are actively looking for pilot instructors. Primary components of our program include an interactive online tutorial program with over 12,000 questions, an instructor review interface, a set of hands-on and imaging- and spectra-driven laboratory exercises, including video tutorials, and interviews with diverse individuals working in STEM fields to help combat stereotypes. We discuss learning strategies often employed by students without substantial scientific
training and suggest ways to incorporate them into a framework based on the scientific method and techniques for data analysis, and we compare cohorts of in-class and
distance-education students
