Educational reform and innovation have been diversified by the development ofnetwork technology. Following the trend of Web 2.0 and the concept of the cloud, manyopen resource websites allow teachers and learners to edit contents based on their needs andto share information for collaboration. Platforms such as teaching blogs, forums, Flickr,YouTube, Myspace, and Facebook have enabled different users to interact and cooperateon a virtual social network (McCarthy, 2010). Web 2.0 increases the width and depth ofnetwork applications as it features user interaction and a bottom-up framework, where usersare creators and editors of content (O’Reilly, 2005). Educational technology implementationhas become more learner-centered (Reigeluth, 1999). El-Hmoudova (2014) suggested thatnew technologies and teaching styles can improve the quality of learning, and that it isnecessary to provide explicit instructions and learning opportunities. The arrival of theCloud Era has led to the potential development of a new form of interpersonal relationshipsin the cloud, and it is impossible to escape from this phenomenon. Many studies havefocused on evaluating the online learning status of university students or adults (Cochrane &Bateman, 2010; Lockyer & Patterson, 2008; Xie & Ke, 2011), but very few of them havebeen on interpersonal interactions of younger learners such as elementary students in acloud-based learning environment (CLE). Drawn upon the need to explore the differencesand effects of CLE and offline learning environment, this study, therefore, investigatedpotential factors affecting elementary school students’ learning performance, learningmotivation, and interpersonal relationships in the cloud.
