Fact Families
Students learn to write fact family problems. Fact families all use the same number.  Using a whole, part, part mat, students use cube trains to write two different addition problems using the same numbers- 2, 8 and 10 (2+8=10, 8+2=10). For the subtraction problems, students use the same cube trains but start with the whole (10) and then break it down into the two parts (2, 8). Write the subtraction sentences with the same numbers- 2, 8 and 10 (10-8=2, 10-2=8).  Â
New Learning Methodologies and Tools for Corporate
E-Learning
While e-learning has become accepted in large companies as a standard option for training, most corporate e-learning has not produced the hoped-for performance improvement. Yet elearning has a tremendous amount of unrealized potential to provide high-quality, educationally-sound, engaging training that improves employeesÂ’ performance. Corporate elearningÂ’s lack of success seems to be due to the dearth of widely-publicized methods to teach skills needed by corporate employees, and by the percei
A Parallel Grid-based Implementation for Real Time Processing of Event Log Data in Collaborative App
Collaborative applications usually register user interaction in the form of semi-structured plain text event log data. Extracting and structuring this data is a prerequisite for later key processes such as the analysis of interactions, assessment of group activity, or the provision of awareness and feedback. Yet, in real situations of online collaborative activity the processing of log data is usually done offline since structuring event log data is, in general, a computationally costly process
Semantic Description of Grid Based Learning Services
Grid technology has emerged as a powerful tool to increase the
capabilities of e-learning frameworks. Learning services are fundamental
components representing functionalities that can be easily reused without
knowing the details of how services have been implemented. On the one hand, a
problem that still remains unsolved is how to use and integrate low-level
learning services to compose more complex high-level services or tools that
make sense to both tutors and learners. On the other hand, the
Gardening and Landscaping
As the presence of spring grows stronger, many people's thoughts drift towards their yards and gardens. The websites assembled below provide resources for, and information about, different aspects of gardening and landscaping. Although the pop-up ads are a little intense at the first site (1), persistent navigating will pay off because The Gardener's Network website offers a wealth of information about a variety of subjects including extensive sections on Flowers, Vegetables, House plants, Lawn
Internet Scout Project
This is an article appearing in the January 2002 issue of Scientific American detailing what Advanced Cell Technology (ACT) claims is the first human cloned embryo. This online version describes the research that ACT calls the "dawn of a new age in medicine" and includes links to further information, covering ethical and legal considerations surrounding cloning and the difference between reproductive and therapeutic cloning.
Internet Scout Project
As a free public service, the Emergency Email and Wireless Network provides citizens with email, cell phone, or pager notifications from your local, regional, and national government sources. Users can choose to receive information about severe weather in their area; electric, gas, and water outages; daily weather forecasts; national disaster news; and more. On the registration page, visitors input their email address, home county, zip code, and the type of notification they would like, and can
Internet Scout Project
This website on the Natural History of the Northwoods was created by Boundary Waters Canoe Area Wilderness (BWCAW) enthusiast Earl J.S. Rook. The Flora and Fauna sections are the main features of the site as the Earth and Sky sections are awaiting future development. The Flora section of the site is well organized and extensive, including subsections on Ferns and Fern Allies, Aquatic Plants, Trees, Terrestrial Herbs, and others. Many of the individual flora species link to great photos and detai

Tracking Sunspots
You are about ready to start observing and tracking sunspots across the Sun using real images. You can then use this information to determine the rate of the Sun’s rotation.
Analytical Chemistry
Lecture notes for 1st semester are on titrations, gravimetry, kinetics and electrochemistry (redox). Potentiometry, coulometry, voltammetry, spectroscopic and separation methods are presented during 2nd semester, illustrated with QuickTime animations.

ICED - I Can End Deportation Game
ICED – I Can End Deportation teaches players about current immigration laws on detention and deportation that affect all immigrants: legal permanent residents, asylum seekers, students and undocumented people by violating human rights and denying due process. In the game, players can inhabit one of five immigrant youth, each of a different ethnicity and immigration status. The youth are being chased by immigration officers, while making moral decisions and answering myth and fact questions abo
Lafayette Boulder on Capitol Grounds, Montgomery, Alabama
This image is a black and white photograph of the Lafayette Boulder on the Alabama State Capitol Grounds in Montgomery, Ala. Postcard text: (back) Stone boulder on the Capitol grounds, Montogomery, erected by the Francis Marion Chapter, Daughters of the American Revolution to commemorate the visit of Gen. Lafayette to Alabama in 1825.
DNA Microarray
DNA microarray analysis is one of the fastest-growing new technologies in the field of genetic research. Scientists are using DNA microarrays to investigate everything from cancer to pest control. Now you can do your own DNA microarray experiment! Here you will use a DNA microarray to investigate the differences between a healthy cell and a cancer cell.
Be an Ocean Helper
This OLogy activity shows kids that there are simple, but very helpful things they can do to protect the ocean -- even if they live nowhere near the water. The activity opens by introducing kids to Gabby, a future marine biologist who wants to study dolphins. Then it has a checklist of 14 ways kids can be ocean helpers that includes asking for tap water instead of bottled water and leaving plants and animals where they find them.
Wear a Chimp on Your Wrist
The OLogy activity offers an interesting twist on the study of DNA. Students use colored beads (or gumdrops) to create a bracelet that's based on a section of DNA code. The two strands of the bracelet are then twisted together into a double helix. They can choose to recreate DNA code from a list of favorite plants and animals that includes a monarch butterfly, a chimpanzee, a sunflower, and a brown trout. The activity includes illustrated step-by-step directions.
