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
"80 Rounds in Our Pants Pockets": Orville Quick Remembers Pearl Harbor
The Japanese attack on Pearl Harbor, Hawaii, stunned virtually everyone in the U.S. military: Japan's carrier-launched bombers found Pearl Harbor totally unprepared. In this 1991 interview, conducted by John Terreo for the Montana Historical Society, serviceman Orville Quick, who was assigned to build airfields and was very near Pearl Harbor on December 6, 1941, remembers the attack. He also provided a vivid, and humorous, account of the chaos from a soldier's point of view.
Good Neighbors and Bad: Religious Differences on the Plains in the Early 20th century
The harmony of rural life is often romanticized, but differences among neighbors, whether ethnic, religious or political, could often lead to tension, especially as new groups emigrated west. Ezra and Dan Miller were born in a sod house in North Dakota but migrated with a group of Amish Mennonites to Montana. In this 1981 interview, conducted by Laurie Mercier for the Montana Historical Society, they described how local cowboys reacted to the influx of Amish farmers.
No Way Out: Two New York City Firemen Testify about the 1911 Triangle Shirtwaist Fire
One of the greatest industrial tragedies in U.S. history occurred on March 26, 1911, when 146 workers, mostly young immigrant women, died in a fire at the Triangle Shirtwaist company in New York City. In this brief excerpt from their testimony before the Factory Investigation Commission, New York City Fire Chief Edward F. Croker and Fire Marshall William Beers commented on the safety lapses--the locking of an exit door, the inadequate fire escapes, and the overcrowded factory floor--that led to
Engineering Design Challenges
This site presents challenges faced by NASA engineers who are developing the next generation of aerospace vehicles. The challenges: thermal protection systems, spacecraft structures, electrodynamic propulsion systems, propellers, and personal satellite assistants. Students design, build, test, re-design, and re-build models that meet specified design criteria, using the same analytical skills as engineers.
Determination of DNA Bases Chemistry: A Discovery-Based Experiment
The paper contains details of an electrochemistry lab where students are given the time to explore and design an experiment to identify the different DNA bases. The paper has a very useful compendium of literature relating to electrochemical techniques.
Flow Injection Analysis in the Undergraduate Laboratory
This paper titled, Flow Injection Analysis in the Undergraduate Laboratory, by Rocha and Nobrega was published in the Chemical Educator. It describes two basic experiments. One is the measurement of copper using PAR reagent as carrier in a single line FIA system. Increasing the reaction coil length results in double peaks. Refractive index effects are demonstrated in the two-line system by adding ethanol. The second experiment is the measurement of phosphate with the molybdenum blue reaction

Mars Exploration and Geology Animations
This collection includes QuickTime, MPEG-1, and GIF animations and interactive images of Martian exploration and geology. These visualizations illustrate Mars' surface geology and historical and current water presence and display information from the Spirit, Opportunity, Pathfinder, and Sojourner rovers and landers. Many of the visualizations have long download times, but are well worth your patience. These resources are suitable for use in lectures, labs, or other teaching activities.
Tonto National Monument: Saving a National Treasure
tells the story of the Salado people, who thrived in the Arizona valley where Tonto Creek joins the Salt River (1050-1450 AD). The Salado culture combined customs of several American Indian groups. They channeled the river to create farmland in the desert. They built Pueblo-style buildings. They left no written records. This monument, established in December 1907, was among the first sites protected under the Antiquities Act of 1906.
The aim of this lesson is to enable students to be aware of how to manage their approach to studying to reduce stress. It is the fifth lesson in the study skills series and is intended to support adult learners who are embarking on a course of study and need to acquire skills which will help them to be successful. The lessons are designed as a package with key skills reinforced in each subsequent lesson so that a study culture is developed over time. They can be delivered sequentially or used in
