Light, optics and lenses
Physical Science Content Standard B of the National Science Education Standards encompasses transfer of energy and specifically states, Light interacts with matter by transmission (including refraction), absorption, or scattering (including reflection). We begin with early investigations into the nature of light that culminated in the current understanding of the nature of light, both visible and invisible as the same physical laws apply to the entire electromagnetic spectrum. From there student

Avaliação da Qualidade em Conteúdos Digitais
No âmbito educacional, os conteúdos didácticos são concebidos com a finalidade de levar o aluno a construir determinado conhecimento. A diversidade de soluções tecnológicas educacionais abre novas perspectivas na melhoria da qualidade dos sistemas educativos e simultaneamente vem dando origem a maiores níveis de exigência no que se refere à qualidade dos conteúdos digitais de carácter educativo, tornando cada vez mais necessário desenvolver metodologias e métodos de análise e aval
Every month we will give you a math/statistics brain teaser that lets you test your knowledge with a fun problem.Many of the ideas in these Teasers come from thoughts formed by some of the great mathematical/statistical geniuses in history.
Liberty, Equality, Fraternity: Exploring the French Revolution
This accessible and lively introduction to the French Revolution presents an extraordinary archive of some of the most important documentary evidence from the Revolution, including 338 texts, 245 images, and a number of maps and songs
Four Easy Pieces: Development Systems for Knowledge-Based Generative Instruction
The Experimental Advanced Design Advisor (XAIDA) is a system for the development of computer-based maintenance training. XAIDA acquires knowledge of a device from a subject matter expert and applies common maintenance-training procedures to generate interactive training from the description. XAIDA provides maintenance training in four areas: the physical characteristics of a device, its theory of operation, operating and maintenance procedures, and troubleshooting. XAIDA relies on an instruction
Cancer Statistics, 2003
This Web site contains a recent report on cancer statistics prepared by the American Cancer Society (ACS) that uses incidence data from the National Cancer Institute and mortality data from the National Center for Health Statistics. The report offers "an up-to-date perspective on the occurrence of cancer" in the United States, including cancer frequency, incidence, mortality, and survival statistics for 2003. The Web site provides links to similar articles, the PubMed citation for the report and
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

Mathematics for Computer Science
A basic introduction to Calculus and Linear Algebra. The goal is to make students mathematically literate in preparation for studying a scientific/engineering discipline. The first week covers differential calculus: graphing functions, limits, derivatives, and applying differentiation to real-world problems, such as maximization and rates of change. The second week covers integral calculus: sums, integration, areas under curves and computing volumes. This is not meant to be a comprehensive calcu
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.
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
Vers une nouvelle interface de lecture pour des forums de discussion dédiés à des élaborations c
Dans le cadre de l'apprentissage collaboratif assisté par ordinateur (ACAO ou CSCL), les forums de discussion occupent une place centrale. Si de multiples recherches leur sont consacrées, elles se centrent pour l'essentiel soit sur des méthodes d'analyse a posteriori du contenu, de la dynamique des échanges et des réseaux sociaux, soit sur le calcul d'indices de participation, éventuellement présentés aux participants en cours d'activité. Suite à un symposium de recherche, organisé à
Logic and Proofs is an introduction to modern symbolic logic. It provides a rigorous presentation of the syntax and semantics of sentential and predicate logic. However, the distinctive emphasis is on strategic argumentation. Students learn effective strategies for constructing natural deduction proofs. This learning is supported by the Carnegie Proof Lab: it provides a sophisticated interface, in which students can give arguments by strategically guided forward and backward steps.
Introduction to Stoichiometry
Our on-line Chemistry course covers stoichiometry and demonstrates our scenario based approach to teaching chemistry. Traditional courses tend to follow a bottom-up approach to learning chemistry. This traditional approach teaches abstract concepts and tools before discussing their practical application, which results in students learning bits of unconnected knowledge that are rarely usable let alone memorable. In our approach, scenarios are used both to motivate the material and provide a frame
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
Doris Chase: Artist in Motion
In this 1991 program, the late Doris Chase discusses her work as a painter, sculpter, and video artist. Chase is best remembered as a pioneer in using computer imaging to manipulate video images to create dreamlike, colorful works. Examples of her work, including the acclaimed "Circles II" and snippets from the "By Herself: Table for One" series are shown, with artist commentary.
Risk Management for Enterprises and Individuals
This book is intended for the Risk Management and Insurance course where Risk Management is emphasized. When we think of large risks, we often think in terms of natural hazards such as hurricanes, earthquakes or tornadoes Perhaps man-made disasters come to mind such as the terrorist attacks in the U.S. on September 11, 2001. Typically we have overlooked financial crises, such as the credit crisis of 2008. However, these types of man-made disasters have the potential to devastate the global mark
