Authoring Intelligent Tutoring Systems:
An analysis of the state of the art
This paper consists of an in-depth summary and analysis of the research and development state of the art for intelligent tutoring system (ITS) authoring systems. A seven-part categorization of two dozen authoring systems is given, followed by a characterization of the authoring tools and the types of ITSs that are built for each category. An overview of the knowledge acquisition and authoring techniques used in these systems is given. A characterization of the design tradeoffs involved in buildi
A Simulated Student Can Improve Collaborative Learning
This paper describes a Simulated Student architecture designed to detect and avoid three situations that decrease the benefits of learning in collaboration. These are off-topic conversations, students with passive behaviour and problems related to students learning. In order to check the efficiency of the model in a real case a Simulated Student, which has the features described in the model, was added to a collaborative, synchronous system for learning programming. This paper describes the ex
Google Glass in the Gobi: Prospecting
Last summer, a team led by the Museum's Provost of Science Mike Novacek and Paleontology Division Chair Mark Norell headed to the Gobi for the joint American Museum of Natural History/Mongolian Academy of Sciences expedition. The group included Aki Watanabe, one of Mark Norell's students at the Museum's Richard Gilder Graduate School, who was recently chosen as a beta-tester for Google Glass and who recorded video on Glass throughout the trip. In this video, Watanabe takes us out into the Gobi
Internet Scout Project
Antarctic monthly mean sea surface temperature and pressure data are accessible online from the Carbon Dioxide Information Analysis Center (CDIAC) of Oak Ridge, TN. Compiled by the Climatic Research Unit of the University of East Anglia, UK, this data is an update of temperature. and pressure data collected between 1957-1990 from 29 stations over Antarctica. CDIAC's Web page of this climatic research project displays a map of sampling localities and a table of contents, guiding readers to figure

Navigation interactive pour l'apprentissage en linguistique textuelle
Cet article présente un langage de modélisation des connaissances de visualisation et de navigation et leur implémentation dans une plate-forme logicielle NaviTexte. Nous montrons que cette implémentation nécessite de disposer d' un modèle de texte que nous décrivons. Une application à la linguistique textuelle qui permette à un étudiant de voir et de naviguer dans un texte entre des unités textuelles qui en assurent la cohérence est ensuite présentée.,Preprint
Science in Focus: Force in Motion: Workshop 6: "Force Against Force"
Magnets stick to other magnets and to metal objects made of iron or steel. How much force is required to break the attraction between two magnets? In this workshop, fourth-grade students explore ways to balance the force of magnetism against the force of gravity. A magnet placed in a cup on one side of a pan-balance is stuck to a stationary magnet beneath the cup. When enough washers are placed on the opposite side of the balance, the magnets will separate. Graphical analysis shows some unexpect
RobertNiles.com: Statistics Every Writer Should Know
Robert Niles, a journalist and producer for the LA Times, created this site to help other writers learn the basics of statistics. He explains many key concepts that are essential to report accurate, meaningful numbers and facts. After starting with the fundamentals of mean, median, and percent, Niles goes on to describe more advanced topics like normal distribution, margin of error, and data analysis. For each section, an example or two are provided to demonstrate proper usage of the techniques.
AP U.S. Government & Politics

This course introduces students to the basic concepts, logic, and issues involved in statistical reasoning. Major topics include exploratory data analysis, an introduction to research methods, probability, and statistical inference. The objectives of this course are to give students confidence in manipulating and drawing conclusions from data and provide them with a critical framework for evaluating study designs and results. An important feature of the course is the use of an intelligent tutori
Empirical Research Methods
Regression analysis is an enormously popular and powerful tool, used ubiquitously in the social and behavioral sciences. Most courses on the subject immediately dive into the mathematical aspects of the subject and illustrate the technique on problems that are already highly structured. As a result, most students come away with little idea of the wide range of problems to which regression analysis can be applied and how to represent those problems in a way that cleverly utilizes readily availabl
Does excessive exposure to violent video games cause violent behavior? Does increased gun availability cause more crime or less? Causal claims permeate everyday life and are constantly the subject of "studies" reported in the newspaper. The material in Causal and Statistical Reasoning examines the nature of causal claims and the statistical sorts of evidence used to support them. The material is contained in: approximately 20 content modules, a repository of over 100 short case studies, and a "C
