"Writing is essential to success in school and the workplace. Yet writing is a skill that cannot be learned on the spot; it is complex and challenging. Through NWP's professional development programs, teachers in all subject areas and all grade levels learn new strategies to help their students become accomplished writers and learners. "

OpenSimulator is an open source multi-platform, multi-user 3D application server. It can be used to create a virtual environment (or world) which can be accessed through a variety of clients, on multiple protocols. OpenSimulator allows virtual world developers to customize their worlds using the technologies they feel work best - we've designed the framework to be easily extensible. OpenSimulator is written in C#, running both on Windows over the .NET framework and on *ix machines over the Mono framework. The source code is released under a BSD License, a commercially friendly license to embed OpenSimulator in products. Out of the box, OpenSimulator can be used to simulate virtual environments similar to Second Life™, given that it supports the core of SL's messaging protocol. As such, these virtual worlds can be accessed with the regular SL viewers. However, OpenSimulator is neither a clone of Second Life's server nor does it aim at becoming such a clone. On the contrary, OpenSimulator lacks support for many of the game-specific features of Second Life (on purpose), while pursuing innovative directions towards becoming the bare bones, but extensible, server of the 3D Web. OpenSimulator is getting more stable as it approaches release 1.0, but we still consider it alpha software; so should you. Features * Supports online, multi-user 3D environments as small as 1 simulator or as large as thousands of simulators. * Supports 3D virtual spaces of variable size within one single instance. * Supports multiple clients and protocols - access the same world at the same time via multiple protocols. * Supports realtime Physics Simulation, with multiple engine options including ODE. * Supports clients that create 3D content in real time. * Supports inworld scripting using a number of different languages, including LSL/OSSL, C#, JScript and VB.NET * Provides unlimited ability to customize virtual world applications through the use of scene plugin

Very good article
