A video-analysis software tool has been employed in order to measure the steady-state values of the kinematics variables describing the longitudinal behaviour of a radio-controlled model aircraft during take-off, climbing and gliding. These experimental results have been compared with the theoretical steady-state configurations predicted by the…

This paper presents an ecological model of developing researcher competence, with a particular focus on doctoral students' use of research software. The model extends on theoretical work done by Young et al. ("Instructional Science 30"(1): 47-63, 2002), modelling the intentional dynamics of technological learning contexts. The development of the…

Monitoring the learning process in computer supported collaborative learning (CSCL) environments is a key element for supporting the efficacy of tutor actions. This article proposes an approach for analysing learning processes in a CSCL environment to support tutors in their monitoring tasks. The approach entails tracking the interactions within…

Describes developments in multilevel modeling of educational and other social data. Suggests that such a technique be used for school effectiveness studies, political opinion surveys, and area-based studies. Recommends that the inherent hierarchical structure of social science data be reflected in statistical models. Argues that multilevel…
