    Some observations from the analysis of an online discussion board
    (IEEE, 2012) Ochoa, Sergio; Pino, José; Baloian, Nelson; Antunes, Pedro; Herskovic Maida, Valeria Paz
    Many educators and educational institutions include an online discussion forum in the content management system supporting their courses, because they think such tool facilitates the instructional process. It could be true if we explicitly design the instructional process to take advantage of this tool, but to do so we have to better understand how users actually use online discussion boards. Trying to answer such a question this paper presents a study of discussions occurring in several undergraduate courses in computer science offered by the University of Chile. More specifically, the study was based on the semantic analysis of a representative set of messages registered in eight different courses occurring in a period of two years. The obtained results indicate that the users do not perceive the forum as a learning tool, but as a communication platform that allows them to socialize and address coordination and operative issues related with the courses.

    Understanding presence awareness information needs among engineering students
    (IEEE, 2012) Herskovic Maida, Valeria Paz; Neyem, Hugo Andrés; Ochoa, Sergio F.; Pino, José A.; Antunes, Pedro
    The flexibility and changing nature of loosely coupled work makes presence awareness crucial to promote interactions among collaborators. Undergraduate students, in their efforts to accomplish coursework-related tasks, must deal with having several available channels to interact with others, accessing and sharing educational material, and the need to optimize their time. Most of them work in a loosely coupled way as the main strategy to reduce the effort spent in the educational process. Presence awareness may help them achieve interactions among potential collaborators in this scenario. This paper aims to identify the most suitable presence awareness information to promote on-demand interactions among college students. A study was conducted for this purpose, involving undergraduate engineering students from two universities in Chile. This article also presents a classification of presence awareness mechanisms for loosely-coupled mobile group work.
