Ítem Acceso Abierto Using social network analysis for analysing online threaded discussions(2015-03) Rodríguez Hidalgo, Roberto Carlos; Zhu, Chang; Questier, Frederik; Torres Alfonso, Aida María; Universidad Central "Marta Abreu" de Las Villas. Centro de Estudios de Informática; Vrije Universiteit Brussel; Vrije Universiteit Brussel; Universidad Central "Marta Abreu" de Las Villas. Centro de Estudios de EducaciónThis study analyses the use of online threaded discussions (OTD) through social network analysis (SNA). The participants involved are university students in a Cuban higher education setting. It was conducted in the Programming Technologies course of the Information Sciences, at the Universidad Central “Marta Abreu” de Las Villas (UCLV). Online discussions are part of the blended learning of this course. The social network analysis shows that online discussions reinforced student peer relationships and network dynamics. Furthermore, it is shown that SNA is a useful approach to analyze students’ peer interactions in the digital space by comparing the peer relations before OTD and those during the OTD.Ítem Acceso Abierto Wikis supporting research workshops in higher education(2011-06-15) Rodríguez Hidalgo, Roberto Carlos; Torres Alfonso, Aida María; Zhu, Chang; Questier, Frederik; Universidad Central "Marta Abreu" de Las Villas. Departamento de Tecnología Educativa; Universidad Central "Marta Abreu" de Las Villas. Departamento de Tecnología Educativa; Vrije Universiteit Brussel; Vrije Universiteit BrusselThis paper reports the results of a pilot study conducted on a Cuban Higher Education setting. A classroom of twenty students of the Sciences of Information career at Central University “Marta Abreu” of Las Villas (UCLV) was inquired during the use of a wiki tool supporting a research workshop in the course of Databases Theory (DBT). The purpose of this study is to test the following hypotheses: (1) the collaboration supported by social software reinforces the peer relationships among the students of the class and (2) improves the time efficiency of the students and instructors (stakeholders) participating in these collaborative activities. A survey and several interviews were conducted to gather data about the social network the students formed for studying DBT, and about the time they spent on that. The results of these instruments were contrasted with the results of an observation conducted during the collaborative activities. The data of the students' achievements and social network state using the wiki tool were compared to similar data from other two precedent, non-wiki-supported research workshops. The use of the wiki tool was found effective to reinforce the peer learning relationships, and consequently, to improve their achievements on the subject. Finally, the time spent for accomplishing the collaborative learning activities did not decrease significantly during the use of the social software.
