Un modèle d’élève par l’analyse statistique implicative. Prise en compte du contexte algébri
Le modèle d’élève que nous construisons cherche à donner une représentation fine des compétences cognitives des élèves dans le domaine de l’algèbre. Il se fonde sur les micro-actions enregistrées dans le micromonde Aplusix. Ces actions étant de niveau très fin, nous devons reconstruire les connaissances à un niveau plus abstrait : non pas une action isolée mais un ensemble d’actions « similaires » apparaissant dans un même contexte. Nous utilisons pour cela l’analyse sta
Structuring and merging Distributed Content
A flexible approach for structuring and merging distributed learning object is presented. At the basis of this approach there is a formal representation of a learning object, called attribute structure. Attribute structures are labeled directed graphs representing structured information on the learning objects. When two or more learning objects are merged, the corresponding attribute structures are unified, and the unified structure is attached to the resulting learning object.
Suggestions for including songs into the study of Italian.
Prescribed Novel 2 - Gli Occhiali dOro
Information and headings under which to study Giorgio Bassanis novel "Gli Occhiali dOro", including suggestions for discussion of themes and essay writing. A good knowledge of Italian is required to read the novel in the original.
Derivation of Knowledge Structures for Distributed Learning Objects
Knowledge space theory (Doignon & Falmagne, 1985; Albert & Lukas, 1999; Doignon & Falmagne, 1999) offers a rigorous and efficient formal framework for the construction, validation, and application of e-assessment and e-learning adaptive systems. This theory is at the basis of some existing e-learning and e-assessment adaptive systems in the U.S. and in Europe. Such systems are based on a fixed and local domain of knowledge, where fixed means that the domain does not change in time and local ref
A Woman's Work: Mary Lease Celebrates Women Populists
Women are not often thought of in association with the Populists, but the best-known orator of the movement in the early 1890s was a woman, Mary Elizabeth Lease. Born in Pennsylvania in 1850 to Irish parents, Lease became a school teacher in Kansas in 1870. She and her husband, a pharmacist, spent ten years trying to make a living farming, but finally gave up in 1883 and settled in Wichita. Lease entered political life as a speaker for the Irish National League, and later emerged as a leader of
This lesson introduces the ways that engineers study and harness the wind. Students will learn about the different kinds of winds and how to measure wind direction. In addition, students will learn how air pressure creates winds and how engineers build and test wind turbines to harness energy from wind.
Students explore the impact of changing river volumes and different floodplain terrain in experimental trials with table top-sized riverbed models. The models are made using modeling clay in an aluminum baking pans placed on a slight incline. Water added "upstream" at different flow rates and to different riverbed configurations simulates different potential flood conditions. Students study flood dynamics as they modify the riverbed with blockages or levees to simulate real-world scenarios.
Is That Legal? A Case of Acid Rain
The goal of this activity is to understand how techniques of persuasion (including background, supporting evidence, storytelling and the call to action) are used to develop an argument for or against a topic. Students develop an environmental case study for presentation and understand how a case study is used as an analysis tool.
The Disaster Dynamics project is a learning environment for the study of the unique challenges surrounding natural disasters. By focusing on dynamics, this project emphasizes the complex and emergent interplay between different aspects of the design activities and the extreme event. The website has several educational role-playing simulation games such as decision making under uncertainty, complex systems and emergent properties, understanding design decisions and fostering collaborations.
Collaborative Decision Making: NASA's Deep Impact Mission
The NASA's Deep Impact Mission is used to teach collaborative decision making. This Starting Point Teaching Collection page describes the highly-developed unit plan involving collaborative problem solving using data. The subject is the launch of a probe to investigate the composition of a comet. The students will engage in quantitative risk analysis, role-playing, persuasive writing and speaking, and group decision-making procedures. The students will study the objectives and the risks of the pr
This laboratory activity gives an example of the creativity required when teaching non-native rock types. In order to study igneous and metamorphic rocks in central Florida (a huge area consisting solely of sedimentary rock), geology students examined building stones in downtown St. Petersburg. Each student picked a particular rock type used in a particular way (structure, decorative facade, etc.), performed geologic tests on it, read up on its properties, history, and uses, and prepared a paper
Developmental Signs Testing in Rat Pups
This dataset comes from a study of rats given one of 4 doses of a drug. The resulting pups were tested for developmental signs. Questions from this study refer to the relationship between dosage and developmental response. A text file version of the data is found in the relation link.
Bon Voyage to Bad Boating Habits
Students will learn about common boating-related threats to waterways. They will learn about the problems created in waterways by recreational boaters and discuss ways boaters can change their behaviors to reduce their impact on waterways. Students will also learn about the history of water pollution through a study of the Cuyahoga River. They will create a commercial to raise awareness about boating-related pollution. Exercises will also help students explore the reliability of information on t
Computer - Tool vs. Medium
We have arrived an important juncture in the history of computing in our profession: This history is long enough to reveal clear trends in the use of computing, but not long to institutionalize them. As computers peremate every area of architecture - from design and construction documents to project administration and site supervision - can ?virtual practice? be far behind? In the old days, there were basically two ways of architects working. Under stress. Or under lots more stress. Over time, s
Hot and Cold
What happens to a racquetball when it gets very cold? What happens to neon gas when it gets very hot? In this experiment, liquid nitrogen and Tesla coils are used to study the effects of extreme temperatures on everyday objects.
Thomas Jefferson, Scientist
Thomas Jefferson's passion for politics is rivaled only by his passion for science. Historic Interpreter Bill Barker shares his study of the third president.
An integrated system for computer-aided design and construction of reinforced concrete buildings usi
The study reported in this paper investigates the feasibility of automating the on-site construction of reinforced concrete residential buildings. The basic construction tasks are identified, analyzed and modified with a view towards potential for automation. Emphasis is placed on developing modular forms that facilitate automation. The majority of work in the field of construction robotics has focused on the adaptation of existing industrial robots to automate traditional construction processes
Investigating the evolution of grain scale microstructure during large plastic deformation of polycr
Polycrystalline deformation and its modeling by currently used crystal plasticity models has been investigated by means of experiments involving direct measurement of deformation induced orientation changes. The experiments used a polycrystalline aluminum sample with columnar grains, whose initial lattice orientations were mapped using the Orientation Imaging Microscopy (OIM) technique. The sample was then deformed under (i) simple compression by 40% along the axis of the columnar grains and (ii
