this research study investigated the development of listening proficiency level by the aid of different media- tional artifacts in systemic theoretical instruction (sti). the study considered whether exposing learners to different types and various numbers of mediating artefacts would increase their awareness towards listen- ing concepts after two months, and consequently promote their listenin...

We reflect upon the LADIE project’s experience of migrating a concept of user requirements from the teaching practitioner community to the technical developer community in the light of literature on ‘mediating representations’ and ‘mediating artefacts’. We show that the practical operation of mediating representations is far more complex than previously acknowledged. We suggest that communities...

We present the results of an experiment designed to investigate the mediating role of artefacts in syllogistic reasoning. The aim of the experiment is to compare a new form of representation of the premises, designed according to the Models Theory, with two “classical” representations (Euler circles and Propositions). The results provide preliminary empirical evidence for both hypothesis of the...

Research on collaboration and collaborative learning (CL) has a much longer history than ICT use for learning and collaboration. The emergence of CSCL has brought new possibilities and practices to CL, and facilitated advances in theories of socially constituted learning. The first CSCL tools were products from academic research, often underpinned by theories of collaborative learning. However,...

In spite of high expectations and the support given by prestigious funding and educational institutions, Open Educational Resources (OER) have not been adopted widely by teachers and learners in practice. From a cultural historical activity theory perspective, we argue that Mediating Artefacts (MA) such as OER learning design visual representations and rich narrative pedagogical patterns may en...

this paper presented a multimodal discourse analysis of some visual images in the political rally discourse of 2011 electioneering campaigns in southwestern nigeria. the data comprised purposively selected political visual artefacts from political rallies across the six southwestern states in nigeria (osun, oyo, ondo, ekiti, ogun, and lagos). the data were analyzed using halliday’s (1985) syste...
