Can you draw a picture of the stars on an American flag?
This online activity offers students a chance to analyze possible patterns for the 50 stars on the US flag. Students determine the possible patterns using the clue that each row contains either one more or one less star than the row next to it. The activity is one of 80 mathematical challenges featured on the Figure This! web site, where real-world uses of mathematics are emphasized. The activity features a solution hint and a solution that suggests two ways to think about the problem and shows

Wheel of fortune : who would you guess?
This online activity is based upon the television game show in which contestants try to guess a word or phrase. Students are given a partially completed word puzzle and asked to choose a vowel and three additional consonants. The activity is part of the Figure This! collection of 80 challenges that demonstrate real-world uses of mathematics. This challenge notes the importance of language structure and letter frequency in voice recognition software and cryptography. Students are encouraged to ap
Middle School Portal: Math and Science Pathways (MSP2)
This activity opens with a scenario in which a rack of clothing, originally on sale for thirty percent off the original price, has been discounted by an additional fifty percent. Students are challenged to determine if the new price is actually eighty percent of the original price. The activity, part of the Figure This! collection of 80 real world math challenges, demonstrates that understanding percentages is important for making decisions based upon survey results, interest rates, and medical
Middle School Portal: Math and Science Pathways (MSP2)
This web site contains descriptions and links to more than 60 virtual manipulatives, activities designed to function as concept tutorials. The virtual manipulatives, mostly in the form of Java applets, are designed to facilitate grades 6-8 mathematics learning. By encouraging active student exploration with computers, the virtual manipulatives can help students visualize mathematical relationships. They are organized into five categories based on the National Council of Teachers of Mathematics (
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
California School Garden Network Curriculum
The curriculum section provides over one hundred garden-based lessons to create, expand, and sustain garden-based learning experiences. It offers practical ideas and resources for every level of garden-based learning from sprouting seeds to understanding the food system. This curriculum section was compiled by the University of California Division of Agriculture and Natural Resources Garden-Based Learning Workgroup. The content for this section was borrowed, with permission, from various resour
The ChemWiki project is a new approach toward chemistry education where an Open Access textbook environment is constantly being written and re-written partly by students and partly by faculty members resulting in a free Chemistry textbook to supplement or supplant conventional paper-based books. Anyone can view, although a freely available account is required to edit the site modules.
Logic for Computer Science: Foundations of Automatic Theorem Proving
This book is intended as an introduction to mathematical logic, with an emphasis on proof theory and procedures for constructing formal proofs of formulae algorithmically. This book is designed primarily for computer scientists, and more generally, for mathematically inclined readers interested in the formalization of proofs, and the foundations of automatic theorem-proving. The book is self contained, and the level corresponds to senior undergraduates and first year graduate students. However,
The Adventures of Josie True
The Adventures of Josie True is a web-based historical adventure game for girls. The hero of the game is Chinese-American Josie True, a regular girl who becomes involved in intrigue across time and space as she tries to find her inventor-turned-teacher Ms. Trombone. She time travels with one of Ms. Trombone's inventions, the Intellicat. Includes a guide for teachers and parents with lesson plans. For girls 9-11 years of age. We want to give real girls good content and provide real historical rol
Statistical Methods in Biomedical Imaging
This resource contains the complete materials (syllabus, class notes, assignments, web-based software analysis and visualization tools) for a semester-long upper-division or graduate course on mathematical modeling, statistical analysis and visualization of biomedical imaging data.
Human Rights Lesson Plans for Southeast Asian Schools
This publication is an initial attempt at developing human rights teaching guides for Southeast Asian schools. It is based on the experience of educators in the sub-region in teaching human rights. It is the result of a continuing partnership among educators and institutions in Southeast Asia.
Geography Game: PlaceSpotting
PlaceSpotting is a new geography game based on Google Maps. You get a picture of a place somewhere on earth and some hints and have to find this place on a moveable Google map. You can also create new "map-riddles" for your friends.
It's up to you to provide enough power to meet the energy demands of your city's 3.9 million people while keeping them prosperous, secure, and living in a clean environment. The implications of the energy decisions you make today for your city in 2015 are based on the current lifestyles and the projected energy demands and costs for developed countries throughout North America, Europe and Asia.
Cross Layer Identity Management
This video addresses the problem of today's Internet users who have to pass several authentication and authorization procedures in the usage of Internet services, due to the fact that services consumed require involvement of different service providers. Such a situation exists in a Virtual Organization environment. This video presents the state of the art in federated identity management, the need for cross layer identity management, and approaches followed within the Akogrimo project. This incl

Symptoms of Posttraumatic Stress Disorder in a New Orleans Workforce Following Hurricane Katrina
On August 29, 2005, Hurricane Katrina made landfall resulting in catastrophic damage and flooding to New Orleans, LA, and the Gulf Coast, which may have had significant mental health effects on the population. To determine rates and predictors of symptoms consistent with a diagnosis of posttraumatic stress disorder (PTSD) in New Orleans residents following Hurricane Katrina, we conducted a web-based survey 6 months after Hurricane Katrina made landfall. Participants included 1,542 employees from
Using the Internet to Promote Inquiry-Based Learning
This site is an e-paper that describes a structured approach to inquiry-based learning using the World Wide Web as a primary information resource. Specifically, the paper addresses an 8-step process that begins with an essential question and ends with a product produced by students, typically completed in a cooperative setting. The paper also discusses the skills required by both student and teacher to make inquiry-based learning with the internet a successful endeavor. Finally, the paper discus
