Using Ontological Engineering to Overcome Common AI-ED Problems
This paper discusses long-term prospects of AI-ED research with the aim of giving a clear view of what we need for further promotion of the research from both the AI and ED points of view. An analysis of the current status of AI-ED research is done in the light of intelligence, conceptualization, standardization and theory-awareness. Following this, an ontology-based architecture with appropriate ontologies is proposed. Ontological engineering of IS/ID is next discussed followed by a road map to
Mastering by the teacher of the instrumental genesis in CAS environments: necessity of instrumental
In this article, we study didactic phenomena identified in integration experiments within our classes, CAS(implemented in calculators). From this study, we show the interest of an instrumental approach to understand the influence of tools on the mathematical approach and on the building of students' knowledge: through a process - instrumental genesis - a calculator becomes a mathematical work tool; this process depends on the tool's constraints and potentialities, on students' knowledge, and on
Analyse didactique de protocoles obtenus dans un EIAH en algèbre
Le micromonde APLUSIX permet de garder des traces de l'activité des élèves qui l'utilisent. En effet, il enregistre, dans leur totalité, aussi bien les événements du clavier, que les actions de la souris. Il est ensuite possible de suivre à l'aide d'un "magnétoscope" les évolutions des élèves. Nous avons conduit des expérimentations destinées à établir un état des lieux des connaissances des élèves en algèbre en début d'année scolaire, dans des classes de troisième, seconde
Knowledge, the keystone of TEL design
This talk outlines the arguments supporting the claim that knowledge is the keystone of the design of Technology enhanced learning (TEL) environments. First, I consider the meaning we could attach to knowledge and knowing, and I introduce the notion of conception. Second, I explore how far the problématique of validation is central in our research. And to conclude, I introduce a characterisation of conceptions, which could help in addressing the problem of TEL design at a theoretical level.
Learning Imaging Techniques!
During this activity, students will be introduced to the concepts of the challenge. They will generate ideas for solving the grand challenge first independently, then in small groups. Finally, as a class, students will compile their ideas with a visual as a learning supplement.

Segregated Schooling in Alabama
This scrapbook documents conditions in Birmingham's segregated schools in 1963, as well as white resistance to integration.
This learning object describes the moral theories that are used to justify or clarify health care professionals' clinical decisions.
Levels of Measurement
To understand the different levels of measurement including nominal, ration, ordinal and scale measurements and the arithmetic operations that can be performed on them
Examining ionic and covalent between atoms.
Recognising Nominative Categorative data
Learning Object that introduces Social Science students to recognizing and interpreting data contained in a table. The RLO uses data based on the causes of death of Rock and R&B musicians.
Calculate Molar Absorbance Coefficient
This object helps you to be able to convert units from mM-1 to M-1
Integration of Environmental Analytical Chemistry with Environmental Law: The Development of a Probl
This JCE paper is well written, generous referenced and will serve as an excellent reference for anyone interested in adapting and implementing this problem-based approach to an upper-level environmental analysis laboratory that emphasis QC/QA and performance-based analytical methods.
Middle School Portal: Math and Science Pathways (MSP2)
The popular Learning Adventures series at DiscoverySchool.com (last mentioned in the March 8, 2002 NSDL Physical Science Report) has a feature on the International Space Station. Its assembly is one of the most ambitious engineering projects ever, and this site explains a few of the details of the multi-year process. In the Mission Basics section, there are specific facts, discussions about various aspects of the station, and virtual tours of some of the stations modules. Astronaut profiles and
Tissues of Life
This Web site from the Science Museum of Minnesota offers a fun and interactive way to learn about the structure and function of the body's tissues. While some activities provided are designed to complement an on-site visit to the Tissues of Life exhibit, the Web site also includes many stand-alone Web-based features. For example, with Explore Body Tissues, students can take a look at cross-sections of actual human bodies, browse through a gallery of scar photos (and perhaps add a photo of their
Learning to Learn: An Introduction to Capillary Electrophoresis
This article describes a problem based learning approach to analytical chemistry labs using capillary electrophoresis as the instrumental method. The on-line link requires a password for The Chemical Educator to get the full article. The article also describes a lab that is an example of problem based learning. Students, playing the role of lab technicians, learn how to use the instrument in order to perform an analysis.
Middle School Portal: Math and Science Pathways (MSP2)
A Dictionary of Units of Measurement was written by Russ Rowlett, the Director of the Center for Mathematics and Science Education at the University of North Carolina at Chapel Hill. This Web site provides information on everything from the Metric System to Viscosity Grades and many other measurement units in between. A simple but very useful site, visitors can find answers to their basic unit measurement questions or just have fun learning about some of the common and somewhat obscure ways we m
The Electronic Statistics Textbook
This electronic textbook on statistics provides both extensive and in depth coverage of statistics. Although an excellent reference for analytical chemistry students and faculty, the lack of chemistry-related practice problems or exercises may not make it an appropriate substitute for a traditional text.
This page presents material from the University of Tennessee at Chattanooga Instructional Excellence Retreat, May 1996, on applying cooperative learning in a classroom setting. It gives a nice, quick, summary of cooperative learning, defining it and establishing rules and techniques. The site is for faculty, but is general and not specifically geared to analytical science.
