Mathematical Modeling Using Real Radioactivity Data
In this lab, you can explore how radioactive radiation changes as a function of distance. This curriculum sets the Radioactivity iLab in the context of mathematics curriculum, asking you to consider: What type of mathematical function governs the intensity of radiation over distance?
Policy Analysis of Multi-Actor Systems
This course is about solving complex problems. Our favorite problems are not just technically complex but also characterized by the presence of many different social actors that hold conflicting interests, objectives, and perceptions and act strategically to get the best out of a problem situation. This course offers guidance for policy analysts who want to assess if and how their analysis could be of help, based on the premise that problem formulation is the cornerstone in addressing complex pr
What is the Right Answer
The purpose of this resource is to introduce students to the concept that sometimes there is no one "right" answer to a question or measurement. Students learn to be careful when searching for a right answer to questions such as 'What time is it?' by comparing multiple measurements of the time of day. Students gain an intuitive understanding of the characteristics of imperfect measurements. Using different clocks, students simultaneously record the displayed times. The resulting time measurement
15 year old from Malawi builds windmill using spare parts William Kamkwamba, a school drop-out (his family couldn't afford the fees) who lives in a remote village with no electricity, built his family a windmill using bicycle parts and scrap materials. The young inventor only had a photograph in a primary school textbook on energy to guide him.

ICT use in school: vision and performance measures
The implementation of ICT in schools requires a vision on ICT use in school, the formulation of clear strategic goals, and the planning and organisation of the use of ICT in school. The pursued goals are those points we want to reach for the learner by setting up ICT use in school. At the same time the pursued goals are the results of using ICT as expected by the stakeholders, being the learner, the teacher, the ICT coordinator, and on an indirect way the parents, the environment and the funding
Changes in education: implications for teacher education.
This communication present the implication of the introducing of ICT in teacher training education, at the IUFM of Grenoble.

A Logo-based Task for Arithmetical Activity
Young children attend to answer-getting readings of arithmetical notation. This is evidenced by many childrens exclusive acceptance of a + b = c syntaxes that lend themselves to computational readings (e.g. Behr et al., 1976; Carpenter & Levi, 2000; Knuth, Stephens, McNeil & Alibali 2006). Even those children who do accept a wider variety of syntaxes, such as a + b = b + a and c = a + b , adhere to a computational view involving getting answers to both sides of the equals sign and checking the
Air Bag Design
Do you need proof that driving is a dangerous activity? More Americans have died in car crashes over the past 100 years than in all the wars the U.S. has ever fought combined. More than 40,000 Americans die each year on the nation's highways, most as the result of high-speed collisions. In this video segment adapted from NOVA, learn how engineers developed the air bag, an important automobile-safety device now found in most cars. Recommended for: Grades 3-12
Introduction to Economic Analysis
This book presents introductory economics ("principles") material using standard mathematical tools, including calculus. It is designed for a relatively sophisticated undergraduate who has not taken a basic university course in economics. It also contains the standard intermediate microeconomics material. 328 page pdf.
"A Sop to the Public at Large": Contestant Herbert Stempel Exposes Contrivances in a 1950s Televisio
Television had become the nation's largest medium for advertising by the mid-1950s, when the Revlon cosmetics corporation agreed to sponsor The $64,000 Question, the first prime-time network quiz show to offer contestants fabulous sums of money. As Revlon's average net profit rose in the next four years from $1.2 million to $11 million, a plethora of quiz shows tried to replicate its success. At the height of their popularity, in 1958, 24 network quiz shows--relatively easy and inexpensive to pr
Energy Balance Climate Model
Students explore a Global Energy Balance Climate Model Using Stella II. This Stella model focuses on global energy balance and creating a useful climate model. Students can explore how the model planetary surface and atmospheric temperatures respond to variations in solar input, atmospheric and surface albedo, atmospheric water vapor and carbon dioxide, volcanic eruptions, and mixed layer ocean depth. Climate feedbacks such as water vapor or ice-albedo can be turned on or off. The activity provi
Daisy World Model
The Daisy World model is intended to illustrate a mechanism through which biota might optimize their environment by means of negative feedback. The model offers a very simplified approach to a feedback system and can provide an introductory lesson in how models work. The aim of the model is to implement and test a mathematical model describing possible influence of biota on an abiotic (climatic) system using GAWK and GNUPLOT. The model tests the hypothesis that biota can influence the planetary
Crossroads in Mathematics: Standards for introductory college mathematics before calculus.
Crossroads in Mathematics: Standards for Introductory College Mathematics Before Calculus has two major goals: to improve mathematics education at two-year colleges and at the lower division of four-year colleges and universities and to encourage more students to study mathematics. The document presents standards that are intended to revitalize the mathematics curriculum preceding calculus and to stimulate changes in instructional methods so that students will be engaged as active learners in wo
