“…Instructors can enhance social interactions through choice of online platform-for example, discussion board versus social media (Clarke & Kinne, 2012;Hou, Wang, Lin, & Chang, 2015;Salmon, Ross, Pechenkina, & Chase, 2015)-and type of discussion question posed (Ke, 2010), as well as by incorporating structured collaborative activities and assessments of collaboration (Collazos, Gonzalez, & Garcia, 2014) and focusing on life experience or case-study analysis (Liu & Yang, 2014). Jeong et al (2017) developed a framework for interactions more broadly in online knowledge communities focused on learning and knowledge co-construction, including Wikipedia, citizen science projects, and cMOOCs. As xMOOCs incorporate social learning and knowledge co-construction and, thus, become slMOOCs, such a framework may be helpful in understanding types of interactions and in designing courses consistent with social learning pedagogy.…”
