Building Identity and Community for Early Career Professionals in the Emerging Field of Astrobiology.

To support training and foster retention in the emerging field of astrobiology, NASA has funded opportunities for graduate students and early career scientists to develop a community, foster interdisciplinarity, increase confidence, and showcase career options. The design of these opportunities builds on research on factors that increase retention, including feeling competent, having autonomy and a sense of purpose, having a sense of identity, and being connected to others in the field. Findings are reported from retrospective studies of two NASA career-building opportunities, the Astrobiology Graduate Conference and the International Astrobiology Summer School held in Santander, Spain. We present evidence that attendees gain confidence by presenting to, and working with, their peers, and feel competent to express their ideas and interests and build relationships in the field that continue after the experiences. Many say that they feel less isolated and go on to present or publish with colleagues they meet. Their career options also expand by meeting potential colleagues from different disciplines. Based on the findings, participating in either of these long-running programs shows clear positive impact on early career astrobiology professionals.

Chapter 1: The Astrobiology Primer 3.0.

The Astrobiology Primer 3.0 (ABP3.0) is a concise introduction to the field of astrobiology for students and others who are new to the field of astrobiology. It provides an entry into the broader materials in this supplementary issue of Astrobiology and an overview of the investigations and driving hypotheses that make up this interdisciplinary field. The content of this chapter was adapted from the other 10 articles in this supplementary issue and thus represents the contribution of all the authors who worked on these introductory articles. The content of this chapter is not exhaustive and represents the topics that the authors found to be the most important and compelling in a dynamic and changing field.

Chapter 11: Astrobiology Education, Engagement, and Resources.

Although astrobiology is a relatively new field of science, the questions it seeks to answer (e.g., "What is life?" "What does life require?") have been investigated for millennia. In recent decades, formal programs dedicated specifically to the science of astrobiology have been organized at academic, governmental, and institutional scales. Constructing educational programs around this emerging science relies on input from broad expertise and backgrounds. Because of the interdisciplinary nature of this field, career pathways in astrobiology often begin in more specific fields such as astronomy, geology, or biology, and unlike many other sciences, typically involve substantial training outside one's primary discipline. The recent origin of astrobiology as a field of science has led to strong collaborations with education research in the development of astrobiology courses and offers a unique instructional laboratory for further pedagogical studies. This chapter is intended to support students, educators, and early career scientists by connecting them to materials and opportunities that the authors and colleagues have found advantageous. Annotated lists of relevant programs and resources are included as a series of appendices in the supplementary material.

Astrobiology-Related Virtual Field Trips in Higher Education Settings: A Six-Year Study.

Abstract Astrobiology-related laptop-delivered 360-degree immersive Virtual Field Trips (VFTs) are increasingly used in higher education. However, the literature remains sparse on the experiences in approach to pedagogy and what works and what does not in attaining the intended outcomes. Part of the reason for that has been the limitation on the cost of making this educationally promising type of VFT in terms of time and money, but various initiatives are addressing these two limiting factors. Thus, the pedagogical aspects underpinning making this type of VFT remain largely unexplored. We experimented with the 360-degree VFTs for an astrobiological field site that attracts global researcher interest-the Pilbara Craton of Western Australia, where the world's best preserved and most convincing evidence of early life on Earth exists, from 3.48 billion years ago. Our challenge was to engage final-year undergraduate science students-with little to no geology background-with this field site without visiting it, because of the remote location, safety considerations, and cost. Another consideration was that the astrobiology course in which the VFT resides is fully online, so students not currently residing in Australia can enroll, adding to practical logistical problems for field work. We present our experiences over six years of data in which one pedagogical change stood out above all others-introducing a handwritten field notebook for a VFT-suggesting that it is a key pedagogical consideration for field-related VFTs.

A Method to Increase and Document the Impact of Astrobiology Education and Public Outreach.

Astrobiology education and public outreach (E/PO) efforts vary widely in terms of audience, content focus, duration, intensity, and numerous other characteristics. To identify best practices and gauge impact, an evaluation model is needed that functions across a variety of activities. In 2013, the NASA Astrobiology Institute (NAI) convened 19 astrobiology E/PO specialists for 2 days in Phoenix, AZ, with a professional evaluator to develop an evaluation model. The resulting model, termed the impact analysis method (IAM), is a series of evaluation-based practices that are tied to each phase in the "life cycle" of an E/PO project: beginning with needs assessment, which leads to the articulation of clear measurable objectives, from which design criteria for the project are developed, followed by examining the fidelity of the implementation and measuring the impacts. Data from those measurements were then used by astrobiology E/PO specialists to refine future implementation, collect evidence of impact, and support subsequent program decisions. A rubric was developed to show increasing levels of rigor of the evaluation practices in each phase of the project. Eleven astrobiology E/PO specialists who used the IAM reported increases in their understanding of evaluation and improvements in their programs.

Hidden in the Figures: What Students Are Telling Us About the Effectiveness of Astrobiology Outreach.

Astrobiology is an ideal context to engage students with the processes of science. However, there is a problem in measuring the effectiveness of engaging students with astrobiology where the learning outcome is aimed at improving student views of science. Most studies suggest little to no change in students' views of science, especially in short experiences of hours or days. These studies mostly use quantitative methods, such as numerical scores derived from survey rating scales and responses. We propose that hidden in those figures, the words of students in written survey responses are telling us about the effectiveness of astrobiology outreach at improving understanding of science. We sampled 483 students from multiple high schools involved in an established astrobiology outreach program in Australia, using pre- and postintervention data collected from an open- and closed-form survey to identify the impacts of the program on students' views of science. We applied both conventional quantitative score analysis methods and computer-based qualitative analysis methods-NVivo and Linguistic Inquiry and Word Count (LIWC) programs. While there was little difference in postsurvey scores, there is evidence in the qualitative data that the astrobiology program creates cognitive conflict in students, a trigger to the learning process that can open students to the first steps in understanding the creative, subjective, and tentative nature of science.

An Integrated Approach for Delivering Current Astrobiology Research to the General Public.

This article describes a multifaceted approach to delivering results from current research in astrobiology to visitors at Pacific Science Center, along with the evaluated results of the impact of the work. Content was delivered by (1) training scientists to communicate effectively with the public, (2) providing the trained scientists with venues to engage with the public, and (3) creating two Science on Sphere shows that highlight key tenants scientists are investigating, a hands-on activity to facilitate interactive learning, and a temporary exhibit that highlights current research on the topic. Evaluation of visitors who engaged with each element demonstrates that the content had a large impact on both the increase in knowledge of the visitors and the increase of interest in the topic.

The UK Centre for Astrobiology: A Virtual Astrobiology Centre. Accomplishments and Lessons Learned, 2011-2016.

The UK Centre for Astrobiology (UKCA) was set up in 2011 as a virtual center to contribute to astrobiology research, education, and outreach. After 5 years, we describe this center and its work in each of these areas. Its research has focused on studying life in extreme environments, the limits of life on Earth, and implications for habitability elsewhere. Among its research infrastructure projects, UKCA has assembled an underground astrobiology laboratory that has hosted a deep subsurface planetary analog program, and it has developed new flow-through systems to study extraterrestrial aqueous environments. UKCA has used this research backdrop to develop education programs in astrobiology, including a massive open online course in astrobiology that has attracted over 120,000 students, a teacher training program, and an initiative to take astrobiology into prisons. In this paper, we review these activities and others with a particular focus on providing lessons to others who may consider setting up an astrobiology center, institute, or science facility. We discuss experience in integrating astrobiology research into teaching and education activities. Key Words: Astrobiology-Centre-Education-Subsurface-Analog research. Astrobiology 18, 224-243.

Habitable Worlds: Delivering on the Promises of Online Education.

Critical thinking and scientific reasoning are central to higher education in the United States, but many courses (in-person and online) teach students information about science much more than they teach the actual process of science and its associated knowledge and skills. In the online arena specifically, the tools available for course construction exacerbate this problem by making it difficult to build the types of active learning activities that research shows to be the most effective. Here, we present a report on Habitable Worlds, offered by Arizona State University for 12 semesters over the past 6 years. This is a unique online course that uses an array of novel technologies to deliver an active, inquiry-driven learning experience. Learning outcomes and quantitative data from more than 3000 students demonstrate the success of our approach but also identify several remaining challenges. The design and development of this course offers valuable lessons for instructional designers and educators who are interested in fully capitalizing on the capabilities of 21st-century technology to achieve educational goals.

Secondary School Students' Knowledge and Opinions on Astrobiology Topics and Related Social Issues.

Astrobiology is the study of the origin of life on Earth and the distribution of life in the Universe. Its multidisciplinary approach, social and philosophical implications, and appeal within the discipline and beyond make astrobiology a uniquely qualified subject for general science education. In this study, student knowledge and opinions on astrobiology topics were investigated. Eighty-nine students in their last year of compulsory education (age 15) completed a written questionnaire that consisted of 10 open questions on the topic of astrobiology. The results indicate that students have significant difficulties understanding the origin of life on Earth, despite exposure to the topic by way of the assigned textbooks. The students were often unaware of past or present achievements in the search for life within the Solar System and beyond, topics that are far less commonly seen in textbooks. Student questionnaire answers also indicated that students had problems in reasoning and critical thinking when asked for their opinions on issues such as the potential for life beyond Earth, the question of whether UFOs exist, or what our place is in the Universe. Astrobiology might help initiate student awareness as to current thinking on these matters and should be considered for general science education.

Developing the critical thinking skills of astrobiology students through creative and scientific inquiry.

Scientific inquiry represents a multifaceted approach to explore and understand the natural world. Training students in the principles of scientific inquiry can help promote the scientific learning process as well as help students enhance their understanding of scientific research. Here, we report on the development and implementation of a learning module that introduces astrobiology students to the concepts of creative and scientific inquiry, as well as provide practical exercises to build critical thinking skills. The module contained three distinct components: (1) a creative inquiry activity designed to introduce concepts regarding the role of creativity in scientific inquiry; (2) guidelines to help astrobiology students formulate and self-assess questions regarding various scientific content and imagery; and (3) a practical exercise where students were allowed to watch a scientific presentation and practice their analytical skills. Pre- and post-course surveys were used to assess the students' perceptions regarding creative and scientific inquiry and whether this activity impacted their understanding of the scientific process. Survey results indicate that the exercise helped improve students' science skills by promoting awareness regarding the role of creativity in scientific inquiry and building their confidence in formulating and assessing scientific questions. Together, the module and survey results confirm the need to include such inquiry-based activities into the higher education classroom, thereby helping students hone their critical thinking and question asking skill set and facilitating their professional development in astrobiology.

Report on a NASA astrobiology institute-funded workshop without walls: stellar stoichiometry.

We report on the NASA Astrobiology Institute-funded Workshop Without Walls entitled "Stellar Stoichiometry," hosted by the "Follow the Elements" team at Arizona State University in April 2013. We describe several innovative practices we adopted that made effective use of the Workshop Without Walls videoconferencing format, including use of information technologies, assignment of scientific tasks before the workshop, and placement of graduate students in positions of authority. A companion article will describe the scientific results arising from the workshop. Our intention here is to suggest best practices for future Workshops Without Walls.

Mars for Earthlings: an analog approach to Mars in undergraduate education.

Mars for Earthlings (MFE) is a terrestrial Earth analog pedagogical approach to teaching undergraduate geology, planetary science, and astrobiology. MFE utilizes Earth analogs to teach Mars planetary concepts, with a foundational backbone in Earth science principles. The field of planetary science is rapidly changing with new technologies and higher-resolution data sets. Thus, it is increasingly important to understand geological concepts and processes for interpreting Mars data. MFE curriculum is topically driven to facilitate easy integration of content into new or existing courses. The Earth-Mars systems approach explores planetary origins, Mars missions, rocks and minerals, active driving forces/tectonics, surface sculpting processes, astrobiology, future explorations, and hot topics in an inquiry-driven environment. Curriculum leverages heavily upon multimedia resources, software programs such as Google Mars and JMARS, as well as NASA mission data such as THEMIS, HiRISE, CRISM, and rover images. Two years of MFE class evaluation data suggest that science literacy and general interest in Mars geology and astrobiology topics increased after participation in the MFE curriculum. Students also used newly developed skills to create a Mars mission team presentation. The MFE curriculum, learning modules, and resources are available online at http://serc.carleton.edu/marsforearthlings/index.html.

Life, the universe, and everything: an education outreach proposal to build a traveling astrobiology exhibit.

Astrobiology is a transdisciplinary field with extraordinary potential for the scientific community. As such, it is important to educate the community at large about the growing importance of this field to increase awareness and scientific content learning and expose potential future scientists. To this end, we propose the creation of a traveling museum exhibit that focuses exclusively on astrobiology and utilizes modern museum exhibit technology and design. This exhibit (the "Astrobiology Road Show"), organized and evaluated by an international group of astrobiology students and postdocs, is planned to tour throughout the Americas.

Astrobiology outreach and the nature of science: the role of creativity.

There is concern in many developed countries that school students are turning away from science. However, students may be choosing not to study science and dismissing the possibility of a scientific career because, in the junior secondary years, they gain a false view of science and the work of scientists. There is a disparity between science as it is portrayed at school and science as it is practiced. This paper describes a study to explore whether engaging in science through astrobiology outreach activities may improve students' understanding of the nature and processes of science, and how this may influence their interest in a career in science. The results suggest that the students attending these Mars research-related outreach activities are more interested in science than the average student but are lacking in understanding of aspects of the nature of science. A significant difference was detected between pre- and posttest understandings of some concepts of the nature of science.

The Astrobiology in Secondary Classrooms (ASC) curriculum: focusing upon diverse students and teachers.

The Minority Institution Astrobiology Collaborative (MIAC) began working with the NASA Goddard Center for Astrobiology in 2003 to develop curriculum materials for high school chemistry and Earth science classes based on astrobiology concepts. The Astrobiology in Secondary Classrooms (ASC) modules emphasize interdisciplinary connections in astronomy, biology, chemistry, geoscience, physics, mathematics, and ethics through hands-on activities that address national educational standards. Field-testing of the Astrobiology in Secondary Classrooms materials occurred over three years in eight U.S. locations, each with populations that are underrepresented in the career fields of science, technology, engineering, and mathematics. Analysis of the educational research upon the high school students participating in the ASC project showed statistically significant increases in students' perceived knowledge and science reasoning. The curriculum is in its final stages, preparing for review to become a NASA educational product.

Phantasm of Freud: Nandor Fodor and the psychoanalytic approach to the supernatural in interwar Britain.

The paper examines the appearance of "psychoanalytic psychical research" in interwar Britain, notably in the work of Nandor Fodor, Harry Price and others, including R. W. Pickford and Sylvia Payne. The varying responses of Sigmund Freud and Ernest Jones to the area of research are discussed. These researches are placed in the context of the increasingly widespread use of psychoanalytic and psychological interpretations of psychical events in the period, which in turn reflects the penetration of psychoanalysis into popular culture. The saturation of psychical research activity with gender and sexuality and the general fascination with, and embarrassment about, psychical activity is explored.
