Communication skills play a prominent role in the primary school curriculum. Children are first expected to acquire these skills within a supervised group environment in which the teacher guides and sets the pace for the discussion, and later transfer them to a less dependent setting. This paper describes BetterBlether 1 , a computer mediated educational(More)
Learner-centred design (LCD) is a nebulous concept. It can range from attempts to design with the needs of the learner at the forefront, to involving the learner at various stages of the design process, sometimes throughout the whole process. In addition, learner-centred design involving children implies additional issues which do not present themselves(More)
This paper looks at the particular role which diagrammatic representations, and external representations more generally, play within an educational context. In particular, it considers the way in which the demands on diagrammatic representational systems in educational settings differ with respect to other settings (e.g. professional): in some instances,(More)

This paper describes the Subtle Stone, a tangible handheld tool which supports the communication of emotional experience in the classroom. The results of an initial evaluation suggest that this novel interface is easy to use within a busy working context, and renders the concept of emotion more accessible to young learners. The highly adaptable nature of(More)
This paper describes an analysis scheme which was developed to probe the comprehension of computer programming languages by students learning to program. The scheme operates on free-form program summaries, i.e. textual descriptions of a program which are produced in response to minimal instructions by the researcher/experimenter. The scheme has been applied(More)
