Abstract: 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.

Keywords: Visualization, Simulation, Educational, Cognitive processes, Technology-Enhanced Learning

Abstract: The complexity of mathematics textbooks’ layout has been increasing due to technical advances since the 1960s. Whereas teachers used to be the only authors of textbooks, layout and graphic designers now play a central role in the transmission of knowledge. Design choices in a layout may however confuse learners if the general, didactic, and mathematical meanings interfere. We conducted a semiotic analysis of six textbooks from the 1960s to the 2010s, and built an interactive web-based visualization tool around our observations. The MTTM tool (Math Textbook Time Machine) displays the same mathematics lesson in the design style of six different decades, and allows a user to explore them as if travelling through time. We propose possible uses of this tool in teacher education to raise awareness of the possible confusion induced by design choices.

Abstract: 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.

Abstract: Instant messenger (chat) is one of the means of Computer Supported Collaborative Learning, which may foster students' inter-animation towards joint knowledge construction. However, the analysis and grading of such chats is an extremely time-consuming activity, therefore (semi-)automatic analytics tools are needed. Discourse threads in a chat may become very complex and intertwined, becoming like voices in a polyphonic musical piece. Starting from the polyphonic model, several learning analytics systems were implemented, in which voices and their inter-animation visualization have a central role. This paper tries to analyze the classes of implemented visualizations, from an interdisciplinary perspective.

Abstract: 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 type 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.
