An Approach to Analyzing the Role and Structure of Reflective Dialogue
Several intelligent tutoring systems contain modules that support reflection after practice exercises. However, there is very little research on reflective dialogue and its relation to dialogue during problem solving that can guide this effort. The approach to analyzing educational dialogue described in this paper was developed to address this problem. Using statistical and machine learning methods, we compared the frequency and structure of speech acts by avionics students and experts during pr
ELM-ART: An Adaptive Versatile System for Web-based Instruction

We argue that versatility is an important feature of successful Web-based education systems. We introduce ELM-ART, an intelligent interactive educational system to support learning programming in LISP. ELM-ART provides all learning material online in the form of an adaptive interactive textbook. Using a combination of an overlay mod
A Generic Platform for the Systematic Construction of Knowledge-based Collaborative Learning Applica
This study aims to explore the importance of efficient management of event information generated from
group activity in collaborative learning practices for its further use in extracting and providing knowledge
on interaction behavior. The essential issue here is how to design a platform that can be used for real,
long-term, complex collaborative problem-solving situations and which enables the instructor to both
analyze group interaction effectively and provide an adequate support when needed.
Simulating Human Tutor Dialog Moves in AutoTutor
This purpose of this paper is to show how prevalent features of successful human tutoring interactions can be integrated into a pedagogical agent, AutoTutor. AutoTutor is a fully automated computer tutor that responds to learner input by simulating the dialog moves of effective, normal human tutors. AutoTutorâs delivery of dialog moves is organized within a 5-step framework that is unique to normal human tutoring interactions. We assessed AutoTutorâs performance as an effective tutor and conve
MArCo: Building an Artificial Conflict Mediator to Support Group Planning Interactions
The emphasis on building co-operative/collaborative environments has brought out the matter of group interactions. This, in its turn, has highlighted the issue of conflicts, inherent to group problem solving. If well employed, conflicts can act as triggers of cognitive changes, and thus help to refine the group's solution to the task. In this paper, we present a computational framework for detecting and mediating Meta-Cognitive conflicts. The theoretical framework presented here enables a comput
Looking Ahead to Select Tutorial Actions: A Decision-Theoretic Approach
We propose and evaluate a decision-theoretic approach for selecting tutorial actions by looking ahead to anticipate their effects on the student and other aspects of the tutorial state. The approach uses a dynamic decision network to consider the tutors uncertain beliefs and objectives in adapting to and managing the changing tutorial state. Prototype action selection engines for diverse domains calculus and elementary reading illustrate the approach. These applications employ a rich mod
Synchronous computer mediated collaborative activities among collocated students: Conditions that ma
Synchronous collaborative activities are usually studied in conditions where teachers and students are physically separated. Is there any possibility to apply these activities when all participants are collocated? Does this collocated collaboration setting seems meaningful and for what reasons? Is the quality of learning and teaching process satisfactory high? Under what conditions? The present research explores the previous questions. More
specifically, it explores synchronous computer mediated
CIEL: setting the stage for integrated inquiry learning
We present an integrated framework for the design, authoring, and evaluation of innovative learning scenarios for Collaborative Inquiry and Experiential Learning (CIEL). This framework has been designed to promote interoperability in environments for productive, open-ended learning, such as inquiry learning, but also learning by design and experiential learning.
The CIEL framework centers around a repository of learner generated learning objects that can be saved, and retrieved in standardized f

Realism in the design process and credibility of a simulation-based virtual laboratory
The credibility of an instructional simulation is a most important issue in distance education, where it may replace hands-on activities. This credibility is based in large part upon verisimilitude, a perception strongly influenced by the simulations realism. This paper presents a case study encompassing the design process of a simulation-based virtual laboratory, which was guided by a realism principle, and an investigation of its credibility among potential users. We found that many characte

We
Changing How and What Children Learn in School with Computer-Based Technologies
Schools today face ever-increasing demands in their attempts to ensure that students are well equipped to enter the workforce and navigate a complex world. Research indicates that computer technology can help support learning, and that it is especially useful in developing the higher-order skills of critical thinking, analysis, and scientific inquiry. But the mere presence of computers in the classroom does not ensure their effective use. Some computer applications have been shown to be more suc
A Grid Approach to Provide Effective Awareness to On-line Collaborative Learning Teams
Providing collaborative learning applications the possibility to offer continuous awareness to on-line collaborative learning teams is a challenging issue since it is essential to keep participants informed of both what is happening and what happened in the learning group.
Moreover, awareness is the basis to enhance collaboration and improve the individual and group performance since it allows to track and assess the collaborative learning process more objectively and to model students' behavio
The Climate Visualizer: Sense-Making Through Scientific Visualization
This paper describes the design of a learning environment, called the Climate Visualizer, intended to facilitate scientific sense-making in high school classrooms by providing students the ability to craft, inspect, and annotate scientific visualizations. The theoretical background for our design presents a view of learning as acquiring and critiquing cultural practices and stresses the need for students to appropriate the social and material aspects of practice when learning an area. This is fo
