With the vertices of these graphs representing learning activities and the edges capturing the pedagogical relationship between activities, individual, team, and class-wide activities are integrated into a consistent whole.
The workflow mechanisms modeled in the graphs enable the construction of scenarios that are richer than those currently implemented in MOOCs. The cognitive states of learners
in two consecutive activities feed a transition matrix, which encapsulates the probability of succeeding in the second activity, based on success in the former. This transition matrix is summarized by a numerical value, which is used as the weight of the edge.
This pedagogical framework is connected to stochastic models, with the goal of making learning analytics more appealing for data scientists. However, the proposed modeling language
is not only useful in learning technologies, it also allows researchers in learning sciences to formally describe the structure of any lesson, from an elementary school lesson with 20 students to an online course with 20,000 participants.

In a previous article, we reported that learning scores were higher for dyads of an 'animations' condition than for dyads of a 'static pictures' condition. Results also showed that offering a persistent display of one snapshot of each animated sequence hindered collaborative learning.

Design problems are proposed by teachers as a way to address theoretical concepts in a practical context. The difficulties encountered by apprentices while creating paper based sketches motivated the development of a tabletop warehouse simulation providing apprentices with a Tangible User Interface in the form of a small-scale model.

We hypothesize that animation promotes the understanding of dynamic systems if delivery features decrease the perceptual and cognitive load of processing the animation. We therefore report an experimental study investigating the effects of two delivery features: the continuity of the information flow (animation vs.

The table, Reflect, addresses the issue of unbalanced participation during group discussions. By displaying on its surface, a shared visualization of member participation, Reflect, is meant to encourage participants to avoid the extremes of over and underparticipation. We report on a user study that validates some of our hypotheses on the effect the table would have on its users.

Even more confusing are systems such as Belvedere for instance in which the task space mediates the construction of an argument, ie a discourse structure.

This generic overview is complemented by a number of small-scale studies, which focus on a specific technology, approach or pedagogical model.

A learning environment is a category of educational software where the learner's task is not to answer a predefined serie of questions but to explore a complex world with the assistance of computational agents. We implemented MEMOLAB as an instance of such a learning environment. In MEMOLAB, the learner creates a psychology experiment and then asks the system to simulate the results.

Whereas personal computers' input devices (keyboard and mouse) and displays (individual screen) are adapted to a single user, interpersonal computers enable distributed control by multiple inputs and are equipped with public displays, where the result of a computation can be shared by a group of users.

The task of the ILE designer is to analyse the structure of this interaction space. In this chapter, we propose to structure it as a sequence of hierarchically integrated sub-spaces. Each interaction sub-space associates a command language with a description language according to a simple chaining principle: the description language of each sub-space corresponds to the command language of the next sub-space.

This new form of management is often referred to as 'orchestration'. In former times, learning technologies were mostly self-‐contained environments, running on a single device. In the last decade, integrated pedagogical scenarios have emerged. They integrate activities at multiple social planes such as individual reading, team argumentation and plenary sessions.

The ambition of such a research is to offer a seamless integration of notes taken on printed paper in our daily interactions with digital documents. Existing studies propose a classification of annotations based on their form and function.

The series was part of a research program entitled'Learning in Humans and Machines'(LHM), launched by Peter Reimann and Hans Spada, and funded by the European Science Foundation.

Computer-supported collaboration scripts generally suffer from the problem of being restrained to a specific learning platform. A standardization of collaboration scripts first requires a specification of collaboration scripts that integrates multiple perspectives from computer science, education and psychology.

The reconfiguration is done using dynamic connection/disconnection of modules and rotations of the degrees of freedom. This paper introduces a new approach to self-reconfiguration planning for modular robots based on the graph signature and the graph edit-distance. The method has been tested in simulation on two type of modules: YaMoR and M-TRAN.

TICCIT et PLATO (Morisson, 1975; Murphy et Appel, 1977) sont deux exemples sur une grande échelle de ce que peuvent être des projets dont le but explicite est de promouvoir un enseignement plus efficace et à un moindre coût.

With the vertices of these graphs representing learning activities and the edges capturing the pedagogical relationship between activities, individual, team, and class-wide activities are integrated into a consistent whole.
The workflow mechanisms modeled in the graphs enable the construction of scenarios that are richer than those currently implemented in MOOCs. The cognitive states of learners
in two consecutive activities feed a transition matrix, which encapsulates the probability of succeeding in the second activity, based on success in the former. This transition matrix is summarized by a numerical value, which is used as the weight of the edge.
This pedagogical framework is connected to stochastic models, with the goal of making learning analytics more appealing for data scientists. However, the proposed modeling language
is not only useful in learning technologies, it also allows researchers in learning sciences to formally describe the structure of any lesson, from an elementary school lesson with 20 students to an online course with 20,000 participants.
