The majority of science learning occurs in informal environments such as museums or aquaria, but also in online spaces such as forums or social media (Falk & Storksdieck, 2010). In a design-based effort, we report here on the examination of the behavioral engagement of a community of followers with social media messages that were systematically produced by researchers on the FOSSIL Project, an NSF-funded project focused on building knowledge and relationships that center on paleontology (I.e. the study of fossils). Focusing Twitter and Facebook, we investigated the following research question: what messaging elements lead to increased behavioral engagement? In this presentation, we concentrate specifically on quantifying behavioral engagement with social media messaging and refining Falk and Dierking's (2013) Contextual Model of Learning (CMoL) as it applies to the social media landscape. We find that community engagement varies dependent on platform, messaging elements such as hashtags, URLs, mentions, and post type. In particular, the use of hashtags without the inclusion of other messaging elements on Twitter showed significantly lower engagement than when used on Facebook. While these findings are significant in and of themselves, we argue that our study provides empirical evidence for use of CMoL with social media.
Paleontology captivates people in the physical spaces of museum exhibits and fossil hunting field trips yet also extends to audiences in online spaces such as Twitter and Facebook via a social media practice known as social paleontology. The FOSSIL Project, a National Science Foundation-funded initiative in the United States (NSF-DRL #1322725), uses social paleontology to bring together paleontologists from across the spectrum of expertise, from novice to expert, as a more formal community. The project includes a public-private partnership between researchers at the University of Florida and a private software development firm, Atmosphere Apps. This case, which illustrates how these two entities worked together to identify, develop, and implement an innovative social media campaign is presented as the result of a three-year (November 2013-December 2016) study which included three iterative cycles of design-based research. The study's scope includes the development of an evidence-based, educative social media messaging campaign and through follower engagement delimits the people and institutions that constitute the community as it exists social ecosystem niches. Aside from a basic understanding that followers engage with photo posts and posts with intriguing headlines, limited research exists involving the use of formal learning as a framework for examining the effectiveness of messaging. Using marketing materials produced by Atmosphere Apps that were based on an assessment of the interests and needs of community members, including color schemes and branded fonts, researchers created separate social messaging campaigns for Twitter and Facebook. Best practices from various fields were merged to create quality messages including: graphic design principles, use of marketing-centric messaging strategies, and use of educative strategies for sustaining engagement in science learning. The results of this study, including the public-private partnership between Atmosphere Apps and the FOSSIL Project serves as an example for others who seek to create educative social media engagement.
The FOSSIL Project, an NSF-funded initiative, seeks to unite amateur and professional paleontologists in the practice of social paleontology —an inclusive form of computer-supported collaborative inquiry of the natural world through the collection, preparation, curation, and study of fossils (Authors, 2016). Social paleontology is enacted across a digital habitat of technologies (Wenger, White, & Smith, 2009) that includes Facebook, Twitter, as well as an online social space of our design. Wenger's (1998, 2000) construct of community of practice serves as the theoretical framework for our design. The purpose of this study was to explore the relationship between potential community members' social media personas and their mental model of social paleontology. We examine the responses of citizens, amateurs, and professional paleontologists who completed a survey, a mental model task concerning the meaning of social paleontology and a follow-up interview. In addition to building our capacity to successfully design a community-centered social space, the results inform our understanding of contemporary science learning, that which is inherently social, technology-mediated, occurs outside of formal schooling, involves people from across the lifespan , and recognizes the value of situated practice.
Considerable interest exists among lifelong learners in the USA about fossils and the science of paleontology. Unlike some other science-related groups, e.g., astronomy and ornithology, interest in fossils among amateur paleontologists is primarily focused within local clubs and societies with little national coordination. This paper presents the results of formative evaluation of the FOSSIL project, conducted after the project “Kickoff” meeting held at the NAPC (North American Paleontological Convention) in 2014. FOSSIL is developing a national networked community of practice that includes amateur and professional paleontologists. Our research indicates that more than 60 amateur fossil clubs and societies exist in the USA, of which almost 40 have elected to be part of the FOSSIL network. Overarching goals of this program include enhanced collaborations between amateurs and professionals, knowledge-building about paleontology, access to resources for lifelong learning, and development a viable learning community of practice focused on topics of common and societal interest, such as collections (including digitization), evolution, climate change, and K-12 outreach. In addition to more traditional means such as list-serves and newsletters, FOSSIL is developing an online community (myFOSSIL) and using social media (Facebook and Twitter) to foster communication and interactions among stakeholders, and thus promoting the concept of “social paleontology”.
Social media - in particular microblogging - is fast becoming important in today's world. A good example is Twitter, which is a rich source of readily-available information by, and about, people. Real-life happenings are constantly reported on Twitter; thus, it functions as a 'mirror' to the real world. These happenings range from the banal (individual thoughts, opinions, and observations), to the dramatic (celebrity announcements, scandals, and Internet memes), to real-world events with serious consequences (riots, coordination during natural disasters, response to terrorism, and political dissent). Most extant literature treats the message and user domains on Twitter independently of one another. Current research focuses only on a single domain, but rarely on both. Research consists mostly of specialized techniques, such as opinion and sentiment mining, community detection, social network analysis, and trend mining which are merely applied to Twitter data. Rarely are metadata from both the user and message domains analyzed in tandem with each other. My thesis combines metadata from both domains and transforms them into useful inferences for detecting hidden patterns. The basis of my research is the use of metadata from both Twitter users and messages as the raw material, from which we can discover hidden patterns and inferences. Such patterns and inferences, in turn, can be combined with data mining techniques to unearth a wealth of knowledge about Twitter users in particular, and people in general. In this thesis, I investigate two aspects. First, I introduce a new framework for the large-scale gathering and collation of Twitter user and message metadata. Secondly, I introduce and investigate new inference algorithms that combines metadata from both domains, inspired by current literature, which are hitherto absent in research. In doing so, I contributed to the development of novel inference algorithms, and frameworks to harvest raw metadata from Twitter for the provision of ample data for the evaluation of my algorithms. From the wealth of metadata from the two domains on Twitter, my new algorithms produce three categories of inferences - social demographics, exhibition of online presence by users, and messaging (tweeting) behavior of users. Using these new inference algorithms, I tested my findings on a large-scale real-world dataset, collected from Twitter using data gathering frameworks I have developed. Consequently I was able to draw conclusions of the current 'state of the Twitterverse'. Following that, I introduced a novel application of pattern detection and clustering on inferences generated from my algorithms. This is for the detection of latent traits and identification of non-obvious patterns, with respect to the three categories of inferences that are generated from my algorithms. To conclude my thesis, I showed that my approaches provide useful insights about serious real-world phenomena captured on Twitter pertaining to - environmental activism, terrorism events, and public disorder - all of which are of interest to researchers, governments, and the media alike. Using the approaches proposed throughout my thesis, I was able to discover the behavior of people in the real world, and illustrated how such real-life behavior is translated into expression and social communication in the online realm. The results from these studies covered in my thesis led to a better understanding of who social media consumers are, how they communicate online, and how behavioral patterns from these users 'mirror' the real-world.
In this paper, we review Twitter and microblog research from 2009–2010 including but not limited to fields such as visualization, HCI, machine learning, computer-supported collaborative work, online social networks, media and social studies. We also propose a categorization scheme for the different aspects of research in microblogging, while improving on the categorization scheme found in earlier surveys.
This study investigated the effects of Internet slang use (inclusive of slang, initialisms, abbreviations, emoji, and hashtags) on perceptions of source credibility among constituents of nonprofit organizations. The author hypothesized that a user’s level of comfort/fluency with digital media would impact how they perceive organizations that use non-standard language online. This study used a content analysis of social media posts from 2 national organizations to analyze patterns of non-standard language use, and applied the engagement index (EI) to quantify constituent engagement actions with those posts on 3 social media channels (Facebook, Twitter, and Instagram). An accompanying survey revealed correlations between digital acculturation and comfort with/willingness to use Internet slang. Results of both investigations support the “moderate and appropriate” use hypothesis. Findings reveal, in part, that “accommodative codeswitching” (in the study, using non-standard language) in online communication is an effective, yet powerful and often unwieldy tool for building credibility and fostering engagement with constituents.
Twitter conversations around political issues often quickly polarize with people citing different information sources to make their case and clustering around different influencers who drive different points of view. But Polarized Crowds are not the only way that people gather on Twitter. There are at least six distinct types of conversations on Twitter based on the structure of people’s networks, the subjects and content sources that matter to them, and the way they interact. These networks have different structures that reflect the social activity within them: divided, unified, scattered, clustered, and inward and outward hub and spokes.
In this dissertation, I study the network structure and content of a transnational movement against hydraulic fracturing and shale development, Global Frackdown. I apply a relational perspective to the study of role of digital technologies in transnational political organizing. The core question driving this inquiry is: In what ways are environmental activists using new media technologies to challenge socio-political power structures? I examine the structure of the social movement through analysis of hyperlinking patterns and qualitative analysis of the content of the ties of one European strand of the movement. I explicate three actor types: coordinator, broker, and hyper-local. This research intervenes in the paradigm that considers international actors as the key nodes to understanding transnational advocacy networks. I argue this focus on the international scale obscures the role of globally minded local groups in mediating global issues back to the hyper-local scale. While international NGOs play a coordinating role, local groups with a global worldview can connect transnational movements to the hyper-local scale by networking with groups that are too small to appear in a transnational network. I also examine the movement’s messaging on the social media platform Twitter. Findings show that Global Frackdown tweeters engage in framing practices of: movement convergence and solidarity, declarative and targeted engagement, prefabricated messaging, and multilingual tweeting. Global Frackdown tweeters integrate personal action frames with collective action frames, as well as engage in hybrid framing practices, that I describe as transnational frame jumping. The episodic, loosely-coordinated and often personalized, transnational framing practices of Global Frackdown tweeters support core organizers’ goal of promoting the globalness of activism to ban fracking. Global Frackdown activists use Twitter as a tool to advance the movement and to bolster its moral authority, as well as to forge linkages between localized groups on a transnational scale. In order to contextualize the anti-hydraulic fracturing social movement within the wider mediated discourse on the shale industry, I also study the relative prominence of negative messaging about shale development in relation to pro-shale messaging on Twitter across five hashtags (#fracking, #globalfrackdown, #natgas, #shale, and #shalegas). I analyze the top actors tweeting using the #fracking hashtag and receiving @mentions with the hashtag. Results show statistically significant differences in the sentiment about shale development across the five hashtags. Results show the discourse on the main contested hashtag #fracking is dominated by activists, both individual activists and organizations. The highest proportion of tweeters posting messages using the hashtag #fracking were individual activists, while the highest proportion of @mention references went to activist organizations. These results suggest hashtags can act as cohesive mediated public spheres within and of themselves. Thus, hashtags can be thought of as reflective of, and formative of, distinct “hashtag publics.” This study shows that activism against unconventional fossil fuels brings together very localized concerns about environmental risks associated with extractive industries with more abstract global concerns. I conceptualize this type of movement as a translocal environmental movements, which includes the following dimensions: the fusing of material and symbolic concerns, linkages across affected and potentially affected communities in at least two world regions, a sense of shared interests and goals, and the framing of opposition to shale development in terms of both local concerns and global ones.
The development of information and communication technologies (ICTs) has expanded the ways that people communicate and share information with one another. In the context of disaster, this has disrupted and reshaped the nature of the communication of emergency information and public participation in the emergency response process itself. Members of the public have been much quicker at adapting and improvising solutions in this new communication ecology than emergency response organizations. This difference in adoption reflects key differences in the formal constraints and responsibilities faced by emergency responders in comparison to the ability in the public sphere to improvise and organize more fluidly. My research focuses on the design and ongoing development of sociotechnical solutions within a community of emergency responders interested in integrating social media into emergency response practices. I look at both the solutions emerging across this community and the sociotechnical arrangements that support ongoing communication and the evolution of new ideas in a continual process of invention. My research spans four years, starting with an initial case study and progressing over time into a collaborative role that leverages my skills and knowledge of crisis informatics in the joint exploration of data analysis strategies and communication strategies.
