Can a class of students control a single computer with 30 mice?

Single Display Groupware (SDG) allows multiple people, in the same physical space, to interact simultaneously over a single communal display, through individual input devices that work on the same machine. In this seminar we show how SDG implemented through a computer, a projector, and one mouse per child can be used inside the classroom. We show two experiences. In the first, a participatory approach that makes use of formative assessment for teaching arithmetic’s. Each student must solve a series of mathematical exercises, generated according to their performance through a set of pedagogical rules incorporated into the system. We established statistically relevant results and observed that the software proved most beneficial for the students with the lowest initial results. This happens because the system adapts to the students’ needs, reinforcing the content they most need to work on, thus generating a personalized learning process. In the second experience, making use of the same implementation of SDG, we propose a Computer Supported Collaborative Learning model for big groups within the classroom. The model the work was based on was a Multiple Classification Matrix and the application we built was for learning language (Spanish). The basic collaboration mechanism the model is based on is Silent Collaboration, in which students –through suggestions and exchanges- must compare their ideas to their classmates’. In both approaches the teacher has an active mediating role supported by technology.

Miguel Nussbaum, Doktor der Technischen Wissenschaften, 'Eidgenössische Technische Hochschule' (ETHZ), 1988, is full professor for Computer Science at the School of Engineering of the Pontificia Universidad Catolica Chile. His research is focused in how to transform the classroom experience from the classical teacher oriented to one where students are active learners with projects in Argentina, Brazil, Chile, Guatemala, India, United Kingdom and the United States, and are endorsed by UNESCO. He has published almost 60 journal papers of the ISI catalogue and won the best conference paper award at CSCL 2009.
