Automated Analysis of Students Free-text Answers for Computer-Assisted Assessment
We present an approach to Computer-Assisted Assessment of free-text material based on symbolic analysis of student input. The theory that underlies this approach arises from previous work on DidaLect, a tutorial system for reading comprehension in French as a Second Language. The theory enables processing of a free-text segment for assessment to operate without precoded reference material. A study based on a small collection of student answers to several types of questions has justified our appr
Not So Neutral Views
Students are introduced to acids and bases, and the environmental problem of acid rain. They explore ways to use indicators to distinguish between acids and bases. Students also conduct a simple experiment to model and discuss the harmful effects of acid rain on our living and non-living environment, as well as how engineers address acid rain. In an associated literacy activity, students learn how persuasive techniques are used to develop an argument, and create an environmental case study.
An approach to distance learning curriculum appropriation
The work presented aims at supporting distance learning students in their appropriation of a curriculum. We propose an approach that consists in helping students to construct individual projects. We dissociate different aspects (planning, evaluation and regulation) that can be useful for this purpose, propose a technological approach (epiphyte system, ontology-based model) and example of tools currently provided by the Saafir framework.
Calculus II, Spring 2006
Topics in this course include transcendental functions, techniques of integration, applications of the integral, improper integrals, l'Hospital's rule, sequences, and series.
New tools in Social Practice: Learning, Medical Education and 3D Environments
Learning with different kinds of ICT-based tools is an important issue in todays society. In this article we focus on how design of technology rich environments based on state of the art learning principles can give us new insights about how learning occur, and how we can develop new types of learning environments. Medical education constitutes the subject domain. There has been a considerable effort to develop 3D technologies in this field, and the article provides a careful review of how the
Situational knowledge in physics: The case of electrodynamics
Major difficulties for a novice physics problem solver are how to interpret new problems and how to combine information given in the problem with information already known. A domain expert, by contrast, has the knowledge to take full advantage of problem features at a glance. It takes a long period of practice to acquire such situational knowledge, and it would be desirable for this to be taught more effectively. As a first step, this requires information on how situational knowledge differs acr
Decentralized Service Deployment for Collaborative Environments
In this paper we present the design of a system which allows service deployment in a small-sized group of computers distributed through the Internet. These groups are formed by users who share a common interest, and voluntarily yield their own resources for the achievement of the collaborative activities of the group. Having enough resources contributed by the members of the group, our system guarantees service availability and the fact that the deployment and execution of the services is carrie
The Wellcome Trust Sanger Institute: The Cancer Genome Project
Supported by the Wellcome Trust Sanger Institute, the Cancer Genome Project (CGP) "is using the human genome sequence and high throughput mutation detection techniques to identify somatically acquired sequence variants/mutations and hence identify genes critical in the development of human cancers. This initiative will ultimately provide the paradigm for the detection of germline mutations in non-neoplastic human genetic diseases through genome-wide mutation detection approaches." The CGP websit
Internet Scout Project
The University of Wisconsin at Stevens Point created this website to help "citizens and governments manage the groundwater in Wisconsin wisely, through education, public information, applied research, and technical assistance." Educators and students can find the Wisconsin Groundwater Directory, groundwater factsheets, information on a hands-on groundwater model, and a variety of educational activities. Researchers can learn about the project to develop techniques to monitor and manage groundwat
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
Course 5: Educating for Civil Societies
This final course in the Certificate of Teaching Mastery focuses on the application of teacher training to international development.

Lecture 18 - 11/30/2010
This course covered the mathematical topics most directly related to computer science. Topics included: logic, relations, functions, basic set theory, countability and counting arguments, proof techniques, mathematical induction, graph theory, combinatorics, discrete probability, recursion, recurrence relations, and number theory. Emphasis will be placed on providing a context for the application of the mathematics within computer science. The analysis of algorithms requires the ability to count
Knowledge Convergence in Computer-Supported
Collaborative Learning: The Role of External Representat
This study investigates how two types of graphical representation tools influence the way in which learners use knowledge resources in two different collaboration conditions. In addition, the study explores the extent to which learners share knowledge with respect to individual outcomes under these different conditions. The study also analyzes the relationship between the use of knowledge resources and different types of knowledge. The type of external representation (content-specific vs. conten
The evolution of research on collaborative learning
For many years, theories of collaborative learning tended to focus on how individuals function in a group. More recently, the focus has shifted so that the group itself has become the unit of analysis. In terms of empirical research, the initial goal was to establish whether and under what circumstances collaborative learning was more effective than learning alone. Researchers controlled several independent variables (size of the group, composition of the group, nature of the task, communication
The greenhouse effect visualizer: a tool for the science classroom
The Greenhouse Effect Visualizer (GEV) is designed to help students visualize data sets related to the earth's energy balance. This work was inspired by the benefits scientific visualization have provided to scientists in discovering patterns and presenting the results of their work to broad communities. The hope is that scientific visualization can provide equal assistance to students trying to learn science. The philosophy underlying this approach links learning with practice. Hence, students
Creatures of Habit: A Computational System to Enhance and Illuminate the Development of Scientific T
Creatures of Habit is a computer-based microworld designed to engage middle-to-high school students in the process of scientific inquiry. The system depicts a universe of interacting programmable “creatures” whose individual behavior is guided by simple rules that may model naive psychology, physical laws, chemical affinities, and other domains. Students can create or revise creature rules and explore the resulting (and often surprising) emergent behaviors within “artificial ecosystems”;
Children's mental models of recursive logo programs
Children who had a year of Logo programming experience were asked to think-aloud about what brief Logo recursive programs will do, and then to predict with a hand-simulation of the programs what the Logo graphics turtle will draw when the program is executed. If discrepancies arose in this last phase, children were asked to explain them. A prevaient but misguided "looping" interpretation of Logo recursion was identified, and this robust mental model persisted even in the face of contradiction be
