A short introduction to blogs - how they work and why they matter.
NASA CONNECT Team Extreme: The Statistics of Success
In NASA CONNECT, Team Extreme: The Statistics of Success, focuses on NASA's Space Operations Mission Directorate and the teamwork required to produce a successful space mission. Students will learn about the numerous systems, skills and capabilities involved in a mission and how NASA manages and integrates these systems. Students will draw a parallel between the teamwork used in a NASA mission and find out how teamwork energizes the popular sport of auto racing. Grades 6-8.
Ethno-linguistic Fragmentation, Discrimination, and Access to Clean Water in Mexico
Access to water is very unequal in Mexico and indigenous municipalities are particularly disadvantaged. The paper analyzes empirically the unequal access to water across Mexican municipalities and across individuals for the period of 2000-2005 using regression analysis. The contributions of this paper are two-fold. First, it expands the focus of the literature of ethnic fragmentation and public good provisions from level to distribution; and second, it presents an ethnic fractionalizat
"They Have Largely Destroyed The Pride Of Craft:" Helen Zalph Describes Automation in the Printing I
The introduction of new technologies has always altered the relationship between managers and workers, often by eliminating the need for skilled laborers. Helen Zalph and her colleagues in the printing division of the New York Daily News discovered this fact for themselves when computers revolutionized ...
Union Men Competing Against Each Other: Anne and Al Filardo Describe the Construction Industry in Ne
House building came to a virtual standstill during the depression and war years, a lull that gave way to a massive construction boom that reached far into the postwar period. By that time, however, the nature of the construction industry was undergoing rapid changes. The introduction of new technologies ...
"I Would Like to See Them Outlawed": Citizens Complain to Congress about Sweepstakes Promotions
In the 1960s, lottery-like contests designed to publicize products through sweepstakes competitions spread rapidly. In the 19th century, every state banned lotteries--defined as competitions in which chances to win prizes were sold÷to protect citizens. In 1868, Congress prohibited the distribution of lottery materials through the mail. The mid-20th century sweepstakes, however, did not require contestants to purchase tickets or products to win prizes and were thus considered legal. In 1966, the
Kinetic connections: Bloom's taxonomy in action
An introduction to strategies for using the web to push your students to higher levels of thinking.
Information literacy: not just for students
Good Internet research skills are important for teachers, too. This article provides an introduction to "information literacy" concepts and a list of references for teachers and media specialists.
This page of Statistical Java describes 11 different probability distributions including the Binomial, Poisson, Negative Binomial, Geometric, T, Chi-squared, Gamma, Weibull, Log-Normal, Beta, and F. Each distribution has its own applet.
This is a collection of applets regarding various topics in statistics. Topics include Central Limit Theorem, Probability Distributions, Hypothesis Testing, Power, Confidence Intervals, Correlation, Control Charts, Experimental Design, and Data Analysis.
The Weibull Distribution
This applet allows the user to adjust the alpha (rate) and the beta (scale) parameters of the Gamma distribution with a slider or manual input. The user can also indicate a model (density, hazard, or reliability).
Math in a Sustainable Society

The Changing Workplace
The 20th century ushered in a change from handcrafting to machine tooling. Henry Ford introduced one of the first moving assembly lines as a way to turn out more cars more quickly, and the emerging auto industry popularized this mode. A photo of the Doble Steam Motors Corporation factory shows a line of workers and car chassis in production. This new technology, and the spread of industrialization, changed forever the way that work was completed. A wide variety of industries all across the count
The simulation program Logistic Growth provides the user with a number of ways to graphically analyze, interpret, and understand the behavior of the logistic growth equation and minimum density limited logistic growth equation. The second simulation program allows users to generate a binomial distribution model of blending inheritance.
Sampling is a computer tool designed to help biology students obtain a qualitative understanding of basic concepts related to estimation and statistics. Sampling presents the user with a group of hypothetical populations distributed throughout an area, and with tools for sampling these populations to estimate characteristics such as population size and density, the nature of each population's spatial patterning, and spatial correlations in abundance between populations. By manipulating the numb
