Science in Focus: Force and Motion: Workshop 8. Bend and Stretch
We all expect a spring to stretch or compress when a force is applied, but forces can even deform solid objects like the floor or the top of a table. In this workshop, students in a high school classroom explore ideas about tension and normal force. By applying a force to a spring and measuring the distance the spring is stretched, the students calculate the force constant or stretchiness of the spring. Lecture demonstrations using student volunteers help to illustrate that even rigid objects be
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.
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
