Clustering Students to help Evaluate Learning
In this paper we show how clustering techniques can be applied to student answers generated from a web-based tutoring tool. In particular we are interested in extracting clusters of students based on the mistakes they made using the tool, with the aim of obtaining pedagogically relevant information and providing this feedback to the teacher. The data we used comes from the Logic-ITA, a web-based tutoring tool to practice formal proofs currently in use in the School of Information Technologies at

Platon-1 : quelques dimensions pour l'analyse des travaux de recherche en conception d'EIAH
Le travail présenté dans ce document est centré sur la problématique de la conception des EIAH (Environnements Informatiques pour l'Apprentissage Humain). Dans une première partie, nous proposons une réflexion sur la nature, les objectifs et les difficultés de cette problématique de recherche. Cette analyse conduit à identifier une difficulté centrale, la multiplicité des points de vue qui peuvent intervenir dans un travail lié à la conception d'un EIAH et les incompréhensions prof
Computational Representation of Collaborative Learning Flow Patterns Using IMS Learning Desing
The identification and integration of reusable and customizable CSCL (Computer Supported Collaborative Learning) may benefit from the capture of best practices in collaborative learning structuring. The authors have proposed CLFPs (Collaborative Learning Flow Patterns) as a way of collecting these best practices. To facilitate the process of CLFPs by software systems, the paper proposes to specify these patterns using IMS Learning Design (IMS-LD). Thus, teachers without technical knowledge can p
Usage Analysis Driven by Models in a Pedagogical Context
In the context of distance learning and teaching, the re-engineering process needs a feedback on the learners' usage of the learning system. The feedback is given by interviews, questionnaires, but in the majority of systems, it is given by log files. We consider that it is important to interpret tracks in order to compare the designer's intentions with the learners' activities during a session. In this paper, we present the usage tracking language – UTL. This language was designed to be gener
Semantic Learning Model and Extended Student model: towards an AHAM-based adaptive system
In adaptive hypermedia systems, we distinguish AHAM as the most popular reference model which is based on the Dexter model. Our work consists on building an adaptive system following this model. In this paper, we deal both with the domain and the user's model. On one hand, the domain model called Semantic Learning Model (SLM) is described taking into account the pedagogical structure resulting from our pedagogical segmentation process. On the other hand, our user's model called eXtended Student
Grounding is not shared understanding : distinguishing grounding at an utterance and knowledge leve
This paper argues that for the study and facilitation of collaborative learning, existing theories of grounding such as that of Clark and Shaefer  cannot be applied without adjustments. When comparing collaborative learning and conversation, four dimensions can be identified where grounding at a knowledge level differs from the grounding at an utterance level. Firstly, the indirect access and the existence of a range of manifest meanings, poses the need for a notion of groundedness'. Second
Collaborative Ontological Engineering of Instructional Design Knowledge for an ITS Authoring Environ
Intelligence in an ITS authoring system could rely on content-based engineering of instructional design (ID) knowledge, i.e. based on principles such as conceptualization, standardization and theory -awareness. An ontology - based architecture with appropriate ontologies has been proposed for a theoryaware ITS authoring system. Ontological engineering (OE) as a collaborative process jointly conducted by an OE expert and an ID expert is presented as a step on a roadmap towards a theory-aware ITS
Size and Scale
Another good lesson plan from DiscoverySchool.com, the Size and Scale Web site gives teachers a well conceived and thorough activity on the physics of size and scale. Objectives of the lesson include: understanding the relative sizes of bodies in our solar system and the problem of making a scale model of the entire solar system (because the distances in space are so great that even a very small scale model would be too large to be practical). The site contains all the information needed to comp
Liquid Chromatography Books
This site provides a list of books related to liquid chromatography and its applications. While not immediately pedagogically useful, it may be useful to those seeking texts about LC for their own research interests or to provide as references to students.

Basics of Fluid Mechanics
This book describes the fundamentals fluid mechanics phenomena for engineers and others. This book is designed to replace all introductory textbook(s) or instructor's notes for the fluid mechanics in undergraduate classes for engineering/science students but also for technical peoples. It is hoped that the book could be used as a reference book for people who have at least some basics knowledge of science areas such as calculus, physics, etc.
Architecture and Interior Design for 20th Century America: Samuel Gottscho and William Schleisner
The Gottscho-Schleisner Collection is comprised of over 29,000 images primarily of architectural subjects, including interiors and exteriors of homes, stores, offices, factories, historic buildings, and other structures. Subjects are concentrated chiefly in the northeastern United States, especially the New York City area, and Florida. Included are the homes of notable Americans, such as Raymond Loewy, and of several U.S. presidents, as well as color images of the 1939-40 New York World's Fair.

How To Make A Digi-Brick
This project examines a non-traditional method of construction generated through a digital design process that leverages digital fabrication techniques related to masonry construction. Where as architects? use of computers first affected shape and structure, it is now additionally affecting material, construction, and craft. This design proposal explores these concepts through the production of a wall using simple configuration and reconfiguration of a repeated module adaptable to differing and
Case study of a professional development program: meaningful technology integration in secondary edu
This case study investigated the effects of the design, development, implementation, and evaluation of a professional development program to facilitate the meaningful integration of technology into the curriculum for secondary teachers at a large suburban school. This study addressed the problem of the high cost of technology for a district that had yielded disappointing levels of meaningful technology integration in the teaching and learning process. The professional development program was bas

Exploring Semantic Description and
Matching Technologies for Enhancing the
Automatic Composition of
In the implementation of e-learning frameworks, a problem still unsolved is how to use and integrate low-level learning services to compose more complex high-level services or tools that make sense to both tutors and learners. In that sense semantic description of Grid learning Services appears like a powerful tool to be used for discovering and matching learning services depending of a set of parameters inside the learning framework. These parameters must represent significant functional charac
