Expatriate Spaces, Ex-Soviet Places: Narratives of Americans Abroad in Turn-of-the-Millennium Post-C
The arrival of countless young North Americans into post-Cold War Central and Eastern Europe coincided with a U.S. recession, the collapse of Soviet influence in the former Warsaw Pact countries, and the consequential easing of travel restrictions. I show how overlooked narrative representations of sojourning Western twentysomethings carving out a space for themselves and negotiating their role in a newly internationalized place demonstrate a redefining of the American expat identity as a perfor

Moursund Mathematics Lecture Series. Dr. Jacob Lurie, Lecture 2: “Ambidexterity”
In classical algebraic geometry, there is often a stark difference between the behavior offields of characteristic zero (such as the complex numbers) and fields of characteristic p (such as finite fields). For example, the equation x^p = 1 has p distinct solutions over the field of complex numbers, but only one solution over any field [...]

This Topic in Depth explores the science behind predicting the weather. First, the United States Search and Rescue Task Force describe the basic tools and knowledge used to create weather forecasts (1). Students can find concise, clear explanations of weather, fronts and air masses, high and low pressure, precipitation, and water vapor and humidity as well. By performing the activities presented in the second website, fourth grade students can learn about weather instruments and data collection

Physics learning with a computer Algebra systems: Towards a learning environment that promotes enhan
To become proficient problem-solvers, physics students need to form a coherent and flexible understanding of problem situations they are confronted with. This is important both for solving problems and for interpreting solutions. Still, many students have only a limited representation of the problems they are working on. Therefore, we devised an instructional approach to promote students' understanding of these problems, and to support them in forming associations between problem features and so

Functioning in the Wireless Classroom
Code It! fosters mathematics learning environments where pre-algebra students use handheld technologies to explore and learn about functions. The resources developed - server-based and handheld software and paper-based student and teacher texts - were packaged as a 20-session unit on code making and breaking and designed to boost students' understanding of functions and their facility with the multiple representations of tables, graphs and symbols. We field tested the wireless system with two te

On the cognitive effects of learning computer programming
This paper critically examines current thinking about whether learning computer programming promotes the development of general higher mental functions. We show how the available evidence, and the underlying assumptions about the process of learning to program, fail to address this issue adequately. Our analysis is based on a developmental cognitive science perspective on learning program, incorporating developmental and cognitive science considerations of the mental activities involved in progr

Posing a Scenario and "Looping" to Provide Focus in a Cause/Effect Essay
Most of us are familiar with the idea that in narratives a writer chooses a "hot spot" or critical incident to serve as the focus of the work. Teachers of expository writing also must assist students in finding the "hot spot" or focus of their essays. Use this exercise to help student focus on one aspect of the essay.

Determining the Sources of Delay in a Distributed Learning Environment
In the context of LeGE-WG we expect to see the Open Grid Services Architecture (OGSA) being used as a guiding framework for the future deployment of Distributed Learning Environment (DLEs). OGSA is totally service-oriented and it has been known for sometime that Quality of Service (QoS) is key to the success of DLEs. Delay in particular, as experienced by the end user, is one of the key QoS parameters for a DLE. This paper describes techniques for identifying sources of such delay, and a model f
