With the growing role of online multi-participant collaborations in shaping the academic, professional, and civic spheres, incorporating collaborative online practices in educational settings has become imperative. As more educators include such practices in their curricula, they are faced with new challenges. Assessment of collaborations, especially in larger groups, is particularly challenging. Assessing the quality of the collaborative “thought process” and its product is essential for both pedagogical and evaluative purposes. While traditional quantitative quality measures were designed for individual work or the aggregated work of individuals, capturing the complexity and the integrative nature of high-quality collaborative learning requires novel methodologies. Network analysis provides methods and tools that can identify, describe, and quantify non-linear and complex phenomena. This paper applies network analysis to the content created by students through large-scale online collaborative concept-mapping and explores how these can be applied for the assessment of the quality of a collective product. Quantitative network structure measures are introduced for this purpose. The application and the affordances of these metrics are demonstrated on data from six large-group online collaborative discussions from academic settings. The metrics presented here address the organization and the integration of the content and enable a comparison of collaborative discussions.

Background:. The use of social media is growing tremendously along with its impact on the practice of plastic surgery, for better or for worse. Patients are increasingly using social media to obtain information about either the procedure or the surgeon. Objectives:. The aims of this study were to examine social media posting regarding plastic surgery and to analyze successful online communication methods of the plastic surgeons with the public. Methods:. A prospective analysis of 3 popular, global social media networks was performed, using the English language key phrases “plastic surgery” and “#plastic_surgery.” Three hundred posts related to plastic surgery published on Instagram, YouTube, and Facebook in November 2017 were assessed by the following parameters: author identity, subject (self-promotion, educational, commercial, and personal posts), “social media currency” (likes, shares, comments, and views), and if special effects (videos, photos, etc.) or viral subjects such as reality stars or shaming were utilized. Results:. Sixty-three percentage of the posts on Instagram originated with plastic surgeons, compared with 18% on Facebook and only 13% on YouTube (P < 0.01); together, the plastic surgeons’ posts comprise 31% of the total posts, whereas 49% of posts published by commercial companies (P < 0.01). Most of the posts on Instagram were self-promotional (83%), in comparison to Facebook (29%) or YouTube (6%); P < 0.01. YouTube posts are more personal in nature compared with Instagram and Facebook [39%, 7%, 9%, respectively (P < 0.01)]. Educational content in the posts accounts for only 16% of them, P < 0.01. Shaming is seen in 21% of the posts, especially in Facebook (39%), and mainly related to famous public figures (25%); P < 0.05. Celebrity endorsed posts received more attention in every aspect of social media currency (likes, comments, shares, and views). The use of images of women attracts attention and is widely used in social media posts of plastic surgery (68%). Posts that chose to include videos (22%) are generously rewarded. Online shaming also attracts attention, mostly found in Facebook (39%), and mainly of a public figure (25%). The 10 most powerful attention drawing motives were jokes, attractive female plastic surgeons, celebrities, personal stories, provocative surgeries, videos or photos of surgeries, sex, shaming, and patient education. Conclusion:. Social media have become an important tool for self-promotion and a means to providing better customer service. This trend applies to the plastic surgeon as well. The study’s main insights were to use Instagram, personal stories, educational post, videos and other unique inputs, and involve celebrities in the posts. In general, it would be wise to invest and understand these communication platforms, as they have become the path to dominate the field.
