As an editorial to this special issue, we pinpoint some ways on how visual representations of educational processes can help analyzing these processes, and in turn lead to designing of new tools informed by interdisciplinary research.

The development of argumentative writing skills is necessary and expected in secondary and higher education to foster critical thinking, but they are difficult to master. A computer-supported argumentative writing application, C-SAW, was designed to support this process. In its development and testing, scripts were written to record the use of embedded scaffolding devices and textual changes made. For research purposes, a concept mapping and visualization software (VUE) was used to manipulate and code recorded data to visualize writing process stages for each participant. Further analyses using transitional probability matrices revealed what types of aid were consulted during different stages of writing and which aids and actions were involved in effectively regulating writing processes and strategies. In addition to being useful in analyzing the usability and effectiveness of the technology-enhanced environment, this type of analysis also gave insight into individuals’ writing processes and difficulties and could be used by instructors wishing to provide feedback or adapt their instructional designs.

This paper presents our methodology to capture and model multimodal interactions in Intelligent Tutoring Systems (ITS). We are specifically interested in perceptual-gestural interactions combining perceptions, gestures and other types of actions. Traces of such interactions are multisource and heterogeneous. The challenge is to foster their representation into sequences that render their multimodal nature. In this work, we want to show how the proposed representation yields the analysis of the influence of visual perceptions on learners’ performance. Our case study is the ITS TELEOS, a simulation based Intelligent Tutoring System dedicated to percutaneous orthopedic surgery. We also conducted an experiment on PILOTE 2, a flight simulation environment, to give a proof of concept of the genericity of our propositions.
