E-Assessment using Latent Semantic Analysis
E-assessment is an important component of e-learning and e-qualification. Formative and summative assessment serve different purposes and both types of evaluation are critical to the pedagogical process. While students are studying, practicing, working, or revising, formative assessment provides direction, focus and guidance. Summative assessment provides the means to evaluate a learner's achievement and communicate that achievement to interested parties. Latent Semantic Analysis (LSA) is a st
"We Sang Rock of Ages": Frances Willard Battles Alcohol in the late 19th century
Among the social movements joined and led by women in the late 19th century, including unionization and women's suffrage, none had either the widespread fervor or success enjoyed by the temperance movement. The Woman's Christian Temperance Union (WCTU), founded in 1873, drew widespread support from labor movements such as the Knights of Labor by linking the fight against liquor with the desire to protect home and family against the ravages of the new industrial order. Frances Willard was one of
The Bum as Con Artist: An Undercover Account of the Great Depression
Middle-class observers reacted to hoboes and tramps of the Great Depression with an array of responses, viewing them with suspicion, empathy, concern, fear, sometimes even a twinge of envy. For some, stolidly holding onto traditional values of work and success, the "bum" was suspect, potentially a con artist. Tom Kromer's "Pity the Poor Panhandler: $2 An Hour Is All He Gets" exemplified this stance, urging readers to resist the appeals of panhandlers and refer them to relief agencies, where prof
"I Always Had Pads with Me": A G.I. Artist's Sketchpad, 1943-1944
In the wake of the attack on Pearl Harbor and the declaration of war, thousands of Americans enlisted in the U.S. armed forces. Among them was twenty-year-old Bronx resident Ben Hurwitz. Like many of the men and women who entered military service, Hurwitz (who changed his name to Brown after the war) kept a record of his experiences. But his "journal" was a sketchpad, and, during his two years in North Africa and Italy, Corporal Hurwitz drew and painted at every opportunity. Hurwitz's pictures a
Bruce Kent, ordained a Catholic minister in 1958, became general secretary of the Campaign for Nuclear Disarmament (CND) in 1980 and chairman in 1987, the year he resigned from the ministry. In this video segment, he challenges the damaging spin that secretary for defense Lord Michael Heseltine used to undermine CND rather than engage in public debate about nuclear policy. Kent also refutes accusations that CND was in support of 'one-sided,' full unilateral disarmament. Instead, he argues for 's
GP-B Educator's Guide
This 52-page booklet provides an overview of the history, science and technology of this mission, including an introduction to Einstein's theory of curved spacetime. The guide also contains 18 pages of hands-on classroom activities related to gyroscopes, curved spacetime, frame-dragging and other concepts related to the GP-B experiment.
This website developed by Preetha Ram at Emory is intended to provide web-based support for a problem-based learning exercise focused on forensics. Students work in teams to solve a crime using data from a variety of sources (victim\'s journal, incident reports, coroner\'s reports). The materials are decidedly unique and the approach is likely to be of interest to a large number of faculty and students because of current popular interest in forensics. It should be noted that there are several b
Paper Chromatography of Stains
A paper chromatography experiment separating dyes. The experiment is targeted toward 8-12 grades, but could be suited to an introductory chem laboratory section.The text of the site contains instructions for setting up and executing the experiment in a large class setting.
The Evolution of a Laboratory Syllabus for Quantitative Analysis
The paper contains a syllabus of a redesigned quantitative analysis lab. In its new form, the lab is almost entirely instrumental. The description has sufficient detail to assist a fellow instructor to adopt the experiments. A rationale for the experiments and the lab protocols has also been provided.
US Environmental Protection Agency site that explains GC for those interested in environmental analysis. Assumes some user background in the field.
Study of Electrode Mechanism by Cyclic Voltammetry
This lab experiment uses cyclic voltammetry to determine the concentration of acetaminophen (active ingredient of Tylenol) in a children\'s pain relief elixir and to study the pH dependent mechanism of its oxidation. The experiment includes theory, pre-lab, write-up instructions and reference article.

Reasonable Basic Algebra
Reasonable Basic Algebra is: * An introduction that appeals to the reader's reason rather than to her/his ability to memorize. * A complete tool for teaching "developmental" students twice a week for 15 weeks. * A way for adults to learn some mathematics—more or less in the same spirit as mathematicians do. * A text, with a story-line, written to be read and reread. * A presentation that pays pedantic attention to the linguistic difficulties the reader is likely to have in
A Problem Course in Mathematical Logic
A Problem Course in Mathematical Logic is intended to serve as the text for an introduction to mathematical logic for undergraduates with some mathematical sophistication. It supplies definitions, statements of results, and problems, along with some explanations, examples, and hints. The idea is for the students, individually or in groups, to learn the material by solving the problems and proving the results for themselves. The book should do as the text for a course taught using the modified Mo

Thinking in Three Dimensions
This OLogy activity uses the traditional Japanese art of paper-folding to help kids understand dimensions. The activity begins with a brief introduction to both dimensions and origami. The kids are then given instructions, included as printable PDFs, for morphing 2D paper into 3D models (a simple box and a water bomb).The activity ends with an illustrated look at dimensions, from the zero dimensions of a point to the fourth dimension of time.
