A formative approach to establishing work requirements for a future C2 system
Developing concepts to support cognitive work in a future complex sociotechnical system requires an approach, and supporting analytical tools, with the power to provide design insights for first-of-a-kind systems. This work explored using a work-centred, constraint-based design framework to identify design requirements and propose design concepts for a future, optimized Joint Fires Coordination (JFC) capability for the Canadian Forces. The approach builds on adapting techniques from Cognitive Systems Engineering to model the work constraints of the JFC system and on using the information to systematically identify several hundred design concepts related to its process, technology and organizational structure.
Summary. This paper presents some results of a case study about the characteristics of the interactions between pupils in groupworks, in the context of an innovative teaching experience of Physics at university level. Videorecordings were carried ou t during classes of the unit on Thermodynamics and some pupils from a focal group were interviewed. Analysis focused on group processes from the linguistic, social and cognitive perspectives. Results suggest that sharing cognitive processes by a group o f student, through reasoning and argumentation, may be an answer to the challenges of teaching practice at university level.
