A modelling challenge : untangling learner knowledge
For now about three decades, systematic research on students learning of science and mathematics has evidenced a great variety of the possible understanding for a given notion, as well as an important sensitivity of these understandings to contexts. Students' knowing appears as a tangle of local conceptions of which we have a very partial and unorganised picture. We present here the outlines of the modelling tool we have developed, and of its framework, in order to give account of learners' know
Towards a semantic learning model fostering learning object reusability
We try in this paper to propose a domain model for both author's and learner's needs concerning learning objects reuse. First of all, we present four key criteria for an efficient authoring tool: adaptive level of granularity, flexibility, integration and interoperability. Secondly, we introduce and describe our six-level Semantic Learning Model (SLM) designed to facilitate multi-level reuse of learning materials and search by defining a multi-layer model for metadata. Finally, after mapping dif
Quelques méthodes d'intelligence artificielle pour la modélisation de l'élève
This paper presents some of the artificial intelligence techniques which have been used for student modeling : planning, machine learning, diagnosis and belief revision. Each technique is brie y described, then its application to student modeling is presented and illustrated by a few examples. The advantages and drawbacks of these methods are discussed. We end this survey with some directions for further researches.
Groundwater Detectives
Student teams locate a contaminant spill in a hypothetical site by measuring the pH of soil samples. Then they predict the direction of groundwater flow using mathematical modeling. They also use the engineering design process to come up with alternative treatments for the contaminated water.

Remédiation, Simulation, Argumentation : Analyse de productions d'élèves en électricité
Nous nous intéressons à la modélisation des connaissances mises en œuvre par l'apprenant en situation d'apprentissage basé sur un micromonde en électricité. Nous cherchons à déstabiliser et remédier à des misconceptions et modes de raisonnement erronés en électricité. Nous présentons, dans cet article, notre proposition face à ces différentes problématiques. Celle-ci se compose d'un questionnaire dynamique que nous avons conçu et développé. Nos hypothèses de départ furent
State of the art on Interaction and Collaboration Analysis
The document focuses on students-machine or students-students' interactions analysis that could support students & teachers, when students work in stand-alone mode or in collaborative technology based learning environments. The document concerns the State of the art on the interaction analysis dimensions and approaches that are already applied. The appropriateness of these approaches is related to the learning environments features, the user's profile, the learning activities, and the context of
Looking at Learning...Again, Part 2 Workshop 4. Conceptual Change
With Dr. Peter Hewson. In this workshop, we explore the role played by prior knowledge in the learning of new science ideas. Only when a new idea is understood, accepted, and found to be useful does it begin to be exchanged for a previously held scientific belief. The workshop examines how teachers ideas about teaching and learning may be altered as they engage students in strategies designed to promote conceptual change.,In this class, Dr. Peter Hewson explains his thoughts about conceptual c
14.06 Intermediate Macroeconomic Theory (MIT)
This course is a survey of modern macroeconomics at a quite advanced level. Topics include the neoclassical growth model, overlapping generations, endogenous growth models, business cycles, incomplete nominal adjustment, incomplete financial markets, fiscal and monetary policy, consumption and savings, and unemployment. The course is also an introduction to the mathematical tools used in modern macroeconomics, including dynamic systems, optimal control, and dynamic programming.

Private Universe Project in Mathematics: Workshop 1. Following Children's Ideas in Mathematics
An unprecedented long-term study conducted by researchers at Rutgers University followed the development of mathematical thinking in a randomly selected group of students for 12 yearsfrom first grade through high schoolwith surprising results. In an overview of the study, we look at some of the conditions that made the students math achievement possible.,10 min Building Towers Five-High The Kenilworth students in the fourth grade are seen working on the Towers problem (How many different
TALAT Lecture 1601: Process modelling applied to age hardening aluminium alloys
This lecture describes the methodology for physical modelling of materials problems, with particular emphasis on heat treatment and welding of age hardening alloys materials; it establishes mathematical relations between different process variables (e.g. alloy composition, heat treatment procedure, welding conditions) and the alloy strength or hardness, based on sound physical principles (e.g. thermodynamics, kinetic theory, dislocation mechanics); it motivates faster process development, optimi
Computers in Building: Proceedings of the CAADfutures '99 Conference
This is the eight CAADfutures Conference. Each of these bi-annual conferences identifies the state of the art in computer application in architecture. Together, the series provides a good record of the evolving state of research in this area over the last fourteen years. Early conferences, for example, addressed project work, either for real construction or done in academic studios, that approached the teaching or use of CAD tools in innovative ways. By the early 1990s, such project-based exampl
Toward New Wall Systems: Lighter, Stronger, Versatile
Recent developments in digital technologies and smart materials have created new opportunities and are suggesting significant changes in the way we design and build architecture. Traditionally, however, there has always been a gap between the new technologies and their applications into other areas. Even though, most technological innovations hold the promise to transform the building industry and the architecture within, and although, there have been some limited attempts in this area recently;
Computer as an Metaphorisation Machine
Digital media is transforming the practice and teaching of design. Information technologies offer not only better production and rendering tools but also the ability to model, manipulate, and understand design in new ways. A new era in CAAD has started. One of the aspects of this situation is the increase in the number of computers in design offices and architectural schools (many of our students have their own computers, which a re often better than the computers we have at our school). We can
