    Implementing collaborative learning activities in the classroom supported by one-to-one mobile computing: A design-based process
    (ELSEVIER SCIENCE INC, 2011) Alvarez, Claudio; Alarcon, Rosa; Nussbaum, Miguel
    Mobile devices such as PDAs, smartphones and tablet computers are becoming increasingly popular, setting out opportunities for new ways of communicating and collaborating. Research initiatives have ascertained the potential of mobile devices in education, and particularly, the benefits of incorporating them in the classroom for eliciting collaborative learning and active student participation. However, the development of technology-supported learning environments poses challenges to education researchers, practitioners, and software technologists in creating educational tools that respond to real needs of instructors and learners, meet clearly defined didactic purposes, and are practical for the intended audience. This article reports on a technology for facilitating the implementation of collaborative learning environments in the classroom supported by one-to-one mobile computing. The approach encompasses a framework supporting the design and implementation of the mobile software, and a design-based process that guides interdisciplinary efforts utilizing the framework, towards creating effective pedagogical models based on collaborative learning. The proposed design-based process allowed us to develop pedagogical models that respond to real needs of learners and instructors, where development is grounded on rigorous scientific research, allowing to reuse both knowledge and software, and showing an improvement of the mobile software built based on continuous experimentation and evaluation. A case study illustrating the application of the technology is presented and plans for future research are discussed. (C) 2011 Elsevier Inc. All rights reserved.

    Multiple Mice based collaborative one-to-one learning
    (PERGAMON-ELSEVIER SCIENCE LTD, 2009) Infante, Cristian; Hidalgo, Pedro; Nussbaum, Miguel; Alarcon, Rosa; Gottlieb, Andres
    Exchange is a collaborative learning application, originally developed for wirelessly interconnected Pocket PCs, that provides support for students and a teacher performing a face-to-face computer supported collaborative learning (CSCL) activity in a Single Input/Single Display (SISD) mode. We extend the application to support a single display groupware (SDG) mode. In this new version, named Exchange-MM, three users each with their own mouse (Multiple Mice) interact on a single display with mediation by a technological network. The original collaborative interaction is maintained. We describe a collaborative learning activity and the software architecture that supports both interaction modes, and also present a usability analysis of the activity conducted with second-grade schoolchildren. The results show that as in SISD mode, in SDG with Multiple Mice (MM) the technological network improves communication, negotiation, interactivity, coordination and appropriability between members of collaborative learning groups.
