Tile "mixed-initiative" system-design rationale is explored in the context of networked discourse, in particular in the context of a collaboration model, called DisNet. The frame-based system allows to make contextual relations explicit, but in typical group-projects users can not be expected to formalize the project-context so that it can be used by agents to participate in a collaboration on ...

An important part of “doing” science is engaging in collaborative science practices. To better understand how to support these practices, we need to consider how students collaboratively construct and represent shared understanding in complex, problem-oriented, and authentic learning environments. This research presents a case study centered on the work of four students in a human-centered robo...

The purpose of the research was to identify the ways that narrative accounts were discursively structured to enact, confirm, legitimate, reproduce, or challenge the concept...

The present study is inserted in the scope of discursive practices of students in high school in the context of mathematical education, supported by information and communication technologies. The few opportunities of dialogic interactions offered to these students led the research teacher to propose and analyze a didactic experiment using the internet chats. Therefore, the objective of this st...

For this purpose, this paper takes a critical perspective on information, considers structural characteristics of examination dialog, and ar...
